President Green suspected that the insect tide did not affect David's plan, and the insect tide was nothing to the current college base.

The academy has enhanced the number of defensive missiles at the base. These defensive missiles alone are enough to kill thousands of level 2 Zergs. In addition, there are three extraordinary people here to defend them, so there is no need to worry about the safety of the base.

The last time the "Stone-Skinned Worm" king triggered a worm tide, which actually consumed a lot of Zerg numbers in this area. It has only been not long since. No matter how terrible the Zerg reproduction is, it cannot restore the Zerg's second-level Zerg count in a short period of time.

This requires a lot of energy, and in the ruling planet, energy is scarce.

The next day, David reported to Kenny Superman, and then returned to Aridia First Academy through the portal.

That is, David is now an important combat power of the college base, so he needs to report to Kenny Superman. If ordinary students return to the college, they only need to explain it to the tutor or student union.

David appeared in the portal. He looked at the surrounding environment and felt the air that was completely different from the ruler planet. The air here made people feel relaxed.

Moist, fresh and energetic, is a world of difference from the air that guardian planets dry enough to be filled with the breath of death.

Maybe David was in a particularly good mood today and he felt more sensitive about the environment.

After coming out of the portal, David did not hesitate for a moment. He turned on the identity bracelet while walking and called out the academy's redemption system.

Sure enough, after he had 50,000 points, the perfectly-level heavy axe technique, "Sheng Spirit Heavy Axe Technique", appeared in the redemption list.

David speeded up his pace. He wanted to return to the villa provided by the academy as soon as possible, and exchange it for the "Spirit-Slaying Heavy Axe Technique" there, and then you can check it out directly.

At this time, the rest of the students in the academy were in class and there were almost no students, so David returned to the villa without being disturbed along the way.

As soon as he entered the villa, David immediately clicked on the redemption in the "Spirit-Slaying Heavy Axe Technique", and instantly, 50,000 points were deducted.

What surprised him was that although the "Spirit-Slaying Heavy Axe Technique" showed that it had been redeemed, there was no electronic document available to download.

Just when he was strange, his identity bracelet rang.

"David, have you purchased the 'Spiritual Heavy Axe Technique'?" The principal Lake's extraordinary surprise came over.

"Yes, Principal!" David replied.

"Come to me now!" Principal Lake Chaofan disconnected after he said that.

David knew that this "Spirit-Slaying Heavy Axe Technique" was probably not as simple as electronic documents. It was necessary for the principal Lake Chaofan to see him personally, which should also be related to the "Spirit-Slaying Heavy Axe Technique".

This is David from the principal's office for the first time, but according to the map on the identity bracelet, he found it quickly.

"Master David, the principal is waiting for you, please come in!" The female secretary immediately recognized the strongest genius of the academy when she saw David, and quickly smiled and said while opening the door of the principal's office.

"Thank you!" David responded with a smile and walked into the principal's office.

The principal's office is very ordinary. Except for the large windows and the sun is very sunny, only Lake Superman sitting behind the desk makes the entire office look different.

"Here, sit down first!" Lake Chaofan looked up at David, pointed to the sofa beside him and said.

David immediately sat on the sofa. At this time, the office door opened, and the female secretary walked in with a glass of water and placed it in front of David, and then left quietly.

After about a minute, Lake Chaofan finished what was happening in his hand, then stood up and walked from behind the desk to the sofa opposite David to sit down.

"Is it worth redeeming the 'Spirit Heavy Axe Technique' for 50,000 points? Have you considered it seriously?" Principal Lake Chaofan asked solemnly.

David heard clearly what Principal Lake Chaofan said was to exchange it once, not a book.

"Principal, isn't the 'Spirit of Crushing the Spirit Heavy Axe' a book?" David asked curiously.

"Who told you that the 'Spirit-Slaying Heavy Axe Technique' is a book?" Principal Lake Chaofan looked at David with a funny look and asked.

"What is the 50,000 points redeemed?" David became even more curious.

"'Spirit-Slaying Heavy Axe Technique' is an insight, which is formed by the consumption of the spirit of the master of the heavy axe who has mastered the 'Spiriting Heavy Axe Technique'. Each insight can only be used ten times. After ten times, this insight formed by the spirit will disappear. The college has not produced a heavy axe master who has mastered the 'Spiriting Heavy Axe Technique' for many years, so there are only one insight of the 'Spiriting Heavy Axe Technique', and there are five chances!" Principal Lake Chaofan explained to David.

The "Spirit-Slaying Heavy Axe Technique" is the top technique in the academy's "Spirit-Spiriting Heavy Axe Master". However, once five chances are used up, this set of "Spirit-Spiriting Heavy Axe Technique" will disappear forever.

Unless someone who has accepted the understanding of the "Spirit-Slaying Heavy Axe Technique" breaks through to the Master of Heavy Axe, the First Academy of Aridia will lose this inheritance forever.

So the principal Lake Chaofan couldn't help but make a careful decision, so he asked David to come over and give him a face-to-face assessment.

"I have heard that your master's mastery has reached the master level. Come with me!" A hidden door opened on the wall of the principal's office, and the principal Lake Chaofan said to David.

David followed the principal Lake Chaofan, passed two electronic doors with identity verification, and then took the elevator down for dozens of meters before he arrived at an underground space.

"You take a heavy axe to practice. I need to make sure that your heavy axe master has reached the level of learning the 'Spiritual Crushing Heavy Axe Technique', so that you can use the 'Spiritual Crushing Heavy Axe Technique' to understand it. If you can't achieve it, you can choose to refund 50,000 points, or come to the assessment after you meet the requirements!" Principal Lake Chaofan pointed to the practice heavy axe beside him and said.

David nodded, he was very confident in his mastery of his heavy axe.

He picked up a practice heavy axe, and he raised it over his head. In an instant, his momentum surged and his spirit entered the practice heavy axe in his hand.

Although it was just a practice heavy axe, David's momentum made Principal Lake superb feel that David could avoid a mountain. This was a difficult-to-understand momentum, with a hint of grandmaster's aura.

It is estimated that only the principal Lake Chaofan can understand what the grand master's aura is.

"The Master of the Half-Step Heavy Axe!" Principal Lake Chaofan almost murmured David's Heavy Axe Mastery.

He had long heard that David's heavy axe master was very strong, but David was also a sniper master, which made him look down on David's heavy axe master.

Because it is distracted from the mastery of multiple weapons, especially two completely different weapons, it is almost impossible to get one of them to the extreme.

People have limited energy, and it is difficult to achieve the ultimate mastery of a weapon, let alone when distracted.

But David in front of him obviously broke this statement. David's mastery of heavy axe reached a half-step perfect level. Without inheritance, this was almost beyond the extreme of the heavy axe armored soldier.

Principal Lake Chaofan thought of the creator of the "Spirit-Slaying Heavy Axe Technique", a monster-level genius who used heavy axes two thousand years ago.

This genius has been fighting on the Battle Star for many years, constantly grinding his own mastery of heavy axes, breaking through the limits of mastery of heavy axes again and again.

When this genius reached the limit that the heavy axe armored man could reach, that is, when he mastered the peak-level heavy axe, he met the strongest man from the great world of the gods. The strongest man guided the genius. This genius broke through his understanding of the master of heavy axe and thus reached the realm of the master of heavy axe.

Many years later, before his death, this genius condensed the "Spirit-Slaying Heavy Axe Technique" he founded into an insight and put it into the First Academy of Aridia, hoping to pass on the perfect heavy axe technique he created.

In the next two thousand years, Aridia's First Academy produced three masters of heavy axe, all of which were broken through by this evil genius' "Slaying Heavy Axe Technique". In the end, only one master of the three masters of heavy axe was able to leave a sense of spiritual condensation, and the other two masters of heavy axe died in the battle star.

Over the years, the college’s insights have been consumed and cannot be supplemented.

What surprised the principal Lake Chaofan was that David's talent seemed to be beyond that evil genius.

The monster-level genius reached the peak of mastering the heavy axe in his forties, and after being guided by the strongest man in the great world of the gods, he broke through to the master of the heavy axe.

The Interstellar Federation specializes in technology and powerful energy weapons can destroy planets, but in the study of personal force, the Interstellar Federation and the God-Original World are much different.

Almost the top weapons and techniques that can be passed down in the Interstellar Federation are more or less related to the great world of the gods.

Some are guided by the strongest people in the God-Original World, and some are guided through special items in the God-Original World. In either way, the God-Original World is consciously strengthening the personal combat power of the Interstellar Federation.

"Principal, have I passed the assessment?" David ended a set of 'basic heavy axe techniques' drill. Seeing that Principal Lake Chaofan had not spoken, he couldn't help but ask.

"Of course, David, you passed!" Principal Lake Chaofan came to his senses and nodded.

Principal Lake Chaofan pressed his identity bracelet, and a cabinet appeared on the ground protruding upwards. The cabinet was transparent around it and there was a piece of crystal inside.

David looked at the crystal. Although the crystal did not emit any external light, in his eyes, the crystal had energy similar to the spirit contained in it. This was related to his strong spirit. Ordinary people with spiritual talents could not see these at all.

This mental energy is very solid and is bound by the crystal shell and cannot be released from it.

"David, this is the insight crystal of the 'Spirit of the Heavy Axe Technique'. It is a shell that is consumed by the top krypton crystal as a carrier. Just put your hands on it!" Principal Lake Chaofan said to David while opening the transparent cabinet door of the cabinet.

David nodded heavily. Although Principal Lake Chaofan didn't ask for anything, David could feel that Principal Lake Chaofan had great expectations for him.

He stretched out his right hand and pressed his right hand on the sensation crystal.

Then David felt his spirit and the crystal of perception were connected, and a picture that seemed to be memory and illusion was transmitted into his mind through the spiritual connection.

This illusory picture is very similar to the knowledge light ball of Shadow Master, but the inheritance method of sensation crystals is much lower than that of the knowledge light ball.

Fortunately, David was very strong in spirit, and these illusory images were completely accepted by his spirit, and then he kept repeating these illusory images in his mind.

In the illusory picture, a figure is practicing heavy axe. The various movements of heavy axe cannot be seen clearly, but this is not important.

Because the core of this set of "Sheng Spirit-Slaying Heavy Axe Technique" is not the action of the heavy axe, David saw the spiritual application of the figure in the illusory picture.

The 'Spirit-Slaying Heavy Axe Technique' is actually to use the spirit to establish a spiritual channel around the body. When facing the enemy, the spiritual channel will automatically connect to the enemy's flaws based on the knowledge you have mastered, and then the heavy axe will be issued, and the acceleration will be doubled through the spiritual channel.

The terrifying thing about the "Spirit-Slaying Heavy Axe Technique" is that the cultivated spiritual channel will automatically find the most fatal flaw as long as the master has a thought, and then the heavy axe will kill the enemy from the flaw at high speed.

Users can use this fatal attack in any posture or state without any preparation.

David didn't know how other top-level techniques attacked, but the "Spirit-Slaying Heavy Axe Technique" was too weird and turned the attack into a semi-automatic one.

When facing the enemy, you only need to determine the enemy and then swing the heavy axe.

David tried to mobilize his spirit and began to try according to the way the figure applied to the spirit in the illusory picture.

However, it was not successful at the beginning, and it seemed that the spirit could not become a spiritual channel through the concentration of both hands.

David took the practice heavy axe on the side, and his spirit entered it. After the special shock of the spirit, his spirit turned into a line and stretched out from the practice heavy axe.

Just as this line appeared, there was a wall in David's mind like it was broken, and the line that the spirit turned into seemed to be an extension of his heavy axe.

He felt that no matter where the spiritual line pointed, his heavy axe could appear there in an instant.

The spiritual line stops in the air, and the target is five meters ahead of the farthest end of the spiritual line.

An impulse arose in David's heart, and he wanted to slash out the axe.

His body was slashed out with an axe without any hesitation as he thought.

Just as he practiced the heavy axe, David discovered that it was different from before. When practicing the heavy axe forward with the spiritual line, the power he cut seemed to have accelerated when passing through this spiritual line, and the power and speed increased accordingly.

The practice of heavy axe was extremely fast, but it was so weird that it didn't make any sound. However, when it finally slashed towards the air, the air made a sound.

After this heavy axe was slashed out, David felt that the heavy axe in his hand seemed to have reached another level. The heavy axe broke through the constraints of air. Within five meters, David could slash out instantly, and his attack speed doubled and his power increased by half.
