The next morning, Yisu left the college camp and entered the old battlefield alone. Oh, of course, there were two kittens, one black and one white.

"So, what do you two want to do with me?"

When the Black Cat Doctor forced Yisu's head for the third time, Yisu looked at the two "seniors" with helpless look. He was here to "train" and not to travel! Senior, you are trying to grab monsters like this, how can I swipe my cards?!

"Meow, don't be angry," the doctor licked his paws. "I'm not exercising my muscles and bones. Don't worry, after I move, I will definitely not take action again."

Tess next to him also "meowed" lightly and nodded seriously, but his eyes that were almost crescent-shaped betrayed her heart.

"Looking at the sky."

Yisu covered his face and sighed, stood up with his head tilted for a long time before looking at the doctor again: "So, senior, what do you want to do?"

"Meow, you are so boring."

The doctor shook the beard on his mouth, not hiding his disdain at all, and even admired Yisu's blue veins with a tax-evading look. However, Tess next to him couldn't bear to see it anymore, and arched the doctor's body with his head, and smiled and said, "Meow, stop teasing this child."

"Listen to you."

The doctor turned around and rubbed Tess' head and responded with a smile. Such a warm scene made Yisu feel like he was choking.

"Meow, then I'll just say it. I heard that you are a junior of Sawyer, and that little guy Al also values ​​you very much, so it's like seeing what's special about you. Meow."

The doctor turned his head and added: "Forget it, I have seen it, are there any other means?"

"Will I believe it without you?"

Yisu sighed and waved to the doctor: "Come with me, let's go away before we talk."

"We both?" The doctor's beards were raised: "You can't trust my Tess Meow?"

"Don't bother with the child," Tess arched the doctor's body again and turned to look at Yisu: "I swear in the name of Biyue that I will never reveal your secret to other people, elves and other intelligent creatures, otherwise I will be abandoned by Biyue. Will this reassure you?"

"Okay, but you have to go a little further, at least you have to enter the neutral zone."

Seeing that Tess had brought out the two-month, Yisu naturally had no reason to object, but he still emphasized again that no one was sure whether the academy would set up surveillance measures in its control area. Only when he reached the "neutral zone" outside the control area of ​​the three major forces could he show his abilities with confidence.

"I know, let's go quickly."

The doctor urged, and suddenly turned into a black light and rushed out. He ran towards the neutral zone first. The healing light purified the undead along the way. Tess stepped gracefully on the cat steps, followed Yisu slowly, occasionally taking action to deal with the new undead who suddenly broke out of the ground.

Yisu was also happy to be lazy and happened to avoid throwing cards in the control area of ​​the academy. If it touched the curiosity of those wizards, it would be troublesome. He didn't want to be taken back by the academy to treat it as a new topic for research.

More than an hour later, one person and two cats finally arrived at the so-called neutral area.

The neutral zone is mainly divided into two areas, four areas, part of which is the junction of the three major forces controlled areas, a buffer zone for the three major forces, and a place specially reserved for small forces and three people. Like the three major forces controlled areas, these three areas are also the area most suitable for collecting undead materials on the old battlefield, and are the most active places for small forces and scattered groups.

But Yisu and his friends came to the fourth area, which was the central area of ​​the old battlefield. The black fog transformed from dead energy was shrouded in this land all day long. Few people came here to collect undead materials, which also caused the dead energy here to accumulate more and more, and the undead that spawned became stronger and stronger. Since half a year ago, a team of a college mistakenly entered the central area of ​​the old battlefield and encountered a group of undeads of more than 20 levels, very few people have entered this area.

If the old battlefield is divided into levels, then the outermost area, that is, outside the wooden wall, belongs to the area of ​​the dead energy that affects the dead energy. The dead energy from the old battlefield enters this area with limited access to this area, affecting the vegetation here, but will not give birth to the dead.

Inside the wooden wall, the camp areas of various forces belong to the outer periphery of the old battlefield and are the semi-safe area of ​​the old battlefield. The concentration of dead air here is slightly thicker than the outer periphery. Ordinary green vegetation cannot grow here at all, but as long as there are no corpses, no dead will be born.

Further inwards, it is the periphery of the undead zone, and it is also the periphery of the old battlefield in the true sense. The concentration of dead energy here has exceeded a certain limit. Even if there are no corpses, it will give birth to undead. However, the strength of these undead is very weak, and their general strength is below level ten.

Between the central area and the periphery of the undead area, there is the middle level of the undead area. The undead here is generally above level ten, and occasionally a single undead above level twenty will appear. If you enter this area, you need to lead an awakened master.

As for the central area with the smallest area and the highest level of danger, if there are no more than five awakening masters to form a team, then there will definitely be no life. The undead here is generally above level 20, and there are also groups of people. There are even eyewitness records of undead above level 30. If it weren't for the two masters of doctor and Tess, Yisu would never have chosen to enter this area.

"Are you sure you want to show your abilities here?"

The doctor tilted his head, and a faint halo was shrouded in his body, allowing them to avoid the influence of the dead aura in the central area of ​​the old battlefield.

"Yes, but you need your help."

Yisu said without hesitation. If you don’t hold your thighs, you will be punished by God!

For Yisu now, the couple, the doctor and Tess, are the most standard golden thighs, and there is also a "monster-brushing treasure land" like the central area, which is simply the best opportunity for Yisu to impact the quality of dark steel!

"Meow! For Sawyer's sake..."

The doctor glared at Yisu, as if he had agreed to Yisu's request.

The next action was much simpler. Yisu took two kittens to wander in the central area. Once the figure of the undead was found, the doctor and his wife would go up to solve the problem, and remove the undead's combat ability, leaving only parts such as the skull of a skeleton, the torso of a zombie, the core of the ghost, and handed them over to Yisu's guard Willy for the final blow.

There is no way, Yisu is too bad. Even if the enemy no longer has the ability to counterattack, if he does not use the [Fireball Technique] card, he will not have the ability to kill the enemy. Willy can only take action. After accumulating the killing of twenty-six undeads of more than twenty levels, Yisu finally made his first dark steel card [Armored Skeleton]!

After letting the doctor and Tess look at the cards floating on the dead body for a while, Yisu reached out and grabbed the first dark steel quality card in his life. Just as he touched this [Armored Skeleton], a stream of energy suddenly surged out of the void and poured into Yisu's body unreasonably. Yisu had only time to "ah", then turned his eyes and fell into a coma.

"I always feel like I've seen this situation somewhere."

The doctor rubbed his chin with his claws, and suddenly his eyes lit up: "By the way, it's Sawy! Every time that guy's strength improves, there will be a burst of energy to help him strengthen his body!"

"Don't think about it now, come and see this kid..."
