Han Sanqian put away his fists and subconsciously looked at Zhang Tianfeng.
Zhang Tianfeng explained: "The buildings in this underground city have been nourished by evil spirits for thousands of years. They have become extremely strong and cannot be broken even by gods!"
"I see!"
Han Sanqian suddenly realized.
Afterwards, Zhang Tianfeng observed here for a while and then returned to the ground.
This Xuantian Dusha Formation was extremely powerful, not to mention that he did not dare to step into it easily even after it had existed for thousands of years.
Back on the ground, he had a call with the Sheep King, reported the situation here, and waited for the Canglong Guard to make the decision.
Late at night, Zhang Tianfeng was sitting cross-legged in a tent, but a happy smile appeared on the corner of his mouth, because at this moment, three drops of stone marrow had condensed on the lotus petals of the Ten Thousand Years Stone Heart Lotus he was holding in his hand.
With a thought in his mind, he directly threw the stone marrow into his mouth. After the stone marrow entered his abdomen, he went straight to the Yin and Yang Building Platform under his control.
He could feel Yin Yang's desire for these three drops of stone marrow.
Soon, the stone marrow was integrated into the yin and yang foundation.
Then, the entire foundation platform quickly rotated.
The yin-yang foundation-building platform continued to rotate for half an hour before stopping. Then, a strange force emitted from the foundation-building platform and instantly enveloped Zhang Tianfeng's whole body.
In an instant, Zhang Tianfeng felt that his body and soul were undergoing some kind of huge transformation from the inside out!
"This is……?"
Zhang Tianfeng suddenly remembered that it is said that a monk who has achieved a super-level foundation building will have some kind of qualitative change in his whole person at the moment he achieves a super-level foundation building.
During the transformation, Zhang Tianfeng did not feel that his physical body and soul were strengthened.
After about two minutes, the strange force dissipated.
Zhang Tianfeng immediately sensed himself, and suddenly, some doubts appeared on his face. His soul did not strengthen, his spiritual thoughts did not become more refined, and even his physical body and true energy did not change at all.
However, after carefully sensing it, he felt that he had undergone some kind of transformation, but he didn't know what kind of transformation it was, and he was not a super-level foundation builder in his previous life.
With a thought, his spiritual thoughts sank into the Yin-Yang foundation building platform.
The foundation building platform has indeed reached the highest level, and the internal space has been greatly expanded, enough to accommodate nearly ten thousand drops of true energy liquid.
Taking out the Yuan Jing, Zhang Tianfeng began to practice.
Prepare to fill the space inside the foundation platform with Zhenqi liquid.
Foundation building is divided into early stage, middle stage, late stage and peak stage. Each stage requires a transformation of the true energy.
Upon reaching the peak of foundation building, the true energy liquid will transform into true essence.
The stronger the true energy, the easier it is to form pills.
This is also the origin of the foundation level.
Zhang Tianfeng's yin-yang foundation building platform can hold tens of thousands of drops of true energy. Once it transforms into true essence, it will be easy to form a pill.
Back to business.
As he practiced, Zhang Tianfeng immediately felt something strange.
As we all know, when vitality enters the body, it needs to be transformed through exercises before it can be transformed into one's own true energy.
But this transformation also takes time.
Zhang Tianfeng clearly sensed that the speed of energy transformation was significantly increased this time, about three times.
Fast conversion means fast recovery.
For example, two monks with the same level of cultivation and equal means fight.
If the conversion of one's vitality and true energy is three times that of the other, he can basically maintain his peak condition during the battle. In other words, the longer the battle lasts, the greater the advantage he will have.
"It turns out that this is the advantage of super quality transformation!"
Zhang Tianfeng suddenly realized, and he was quite happy in his heart. Now he only reached the super-grade Yin-Yang Foundation Building Platform. If the Five Emperors Foundation-Building Platform also reached the super-grade level and underwent another transformation, his energy transformation speed might be doubled or tripled.
.
At that time, as long as the enemy cannot kill him instantly, he can drag the opponent to death.
Because the conversion rate increases three times.
This time, it only took Zhang Tianfeng more than an hour to fill up the foundation platform.
Now, his state remains unchanged, but his true energy has almost doubled, which can greatly shorten the time it takes for the Ten Thousand Years Stone Heart Lotus to condense the stone marrow again.
"Brother Zhang!"
At this moment, Han Sanqian's voice came from outside the tent.
Zhang Tianfeng quickly put away Wanzai Shi Xinlian, stood up, and walked out of the tent: "Brother Han, what happened?"
Han Sanqian said solemnly: "The number of infiltrating warriors is increasing, and they all want to sneak into the tomb!"
Suddenly, Zhang Tianfeng frowned. These warriors didn't know the depth. If they went down, they would definitely break into the underground city. With their little cultivation, they would definitely die in the ancient underground city.
If blocked, these warriors will definitely think that they will take advantage of it all.
After thinking for a moment, Zhang Tianfeng said: "Send someone to tell those warriors that the underground ancient city is a formation and no one is allowed to break into it. If you have to enter, don't blame others if you die!"
"good!"
Han Sanqian turned around and left, then ordered his men to contact the warriors.
But there are always many self-righteous and smart people in the world. Even if the people in the Northwest Branch try their best to show that the underground ancient city is dangerous, there are still people who insist on breaking into it.
Moreover, there are quite a lot of people.
Then, everyone who entered the underground ancient city was like a drop of water that merged into the sea and disappeared without a trace in an instant.
See this scene.
The other warriors couldn't help but feel a sense of fear and joy.
The way I look at the ancient underground city is different. I feel like this underground city is a monster that eats people without spitting out their bones.
In the blink of an eye, another two days passed.
More and more warriors gathered here.
During this period, some warriors did not believe the horror of the ancient underground city and plunged into it. Naturally, no one survived and no bones were left.
After experiencing a bloody lesson, these warriors no longer dare to rush into the underground ancient city at will.
The Canglong Guard headquarters has also been unable to come up with a solution for the underground ancient city.
finally.
Time has come to the tenth day mentioned by the mysterious courier.
Without any warning, a beam of light shot up from the ground into the sky, condensing a huge sword shadow in the sky. On the hilt of the sword were two clear ancient characters, which were the two characters "Xuan Yuan".
At the same time, as the sword shadow appeared, a cold, powerful aura containing the aura of a king spread crazily around.
"Oh my God, this is the Xuanyuan Sword!"
"It is indeed a divine weapon. It has such great power. Just the shadow of the sword makes my body stiff and I can hardly move!"
"It seems that the rumors are true. Whoever gets this Xuanyuan Sword will be invincible in the world!"
In the open space, Zhang Tianfeng raised his hand and looked up at the huge sword shadow in the sky, and was quite shocked in his heart. He could sense the power of the sword shadow more clearly. If there were no accidents, the Xuanyuan Sword was an immortal weapon.
Immortal weapon, the existence of a super sect that suppresses luck.
There are actually immortal weapons in a mere earth star.
Even though he had learned that there had been a brilliant cultivation civilization on Earth in ancient times, he still felt inexplicably shocked.
The Xuanyuan Sword is in the tomb below, but to get the Xuanyuan Sword, you have to break the Xuantian Dusha Formation.
With his strength, he couldn't do it unless he found the source of the evil spirit.
Also, what are the people behind the scenes doing?
Could it be that because that person knew that Xuantian Dusha Formation could not be broken, he leaked the news about Xuanyuan Sword and attracted various forces to break the formation?
But even after all the forces join forces to break the formation, is he sure that he can obtain the Xuanyuan Sword?
Moreover, how did he know that Xuanyuan Tomb would be born?
How did he know that there was Xuanyuan Sword and the Elixir of Immortality in the tomb?
Zhang Tianfeng always felt that this incident was too coincidental.
It seems to have been designed by someone.
But now, the development of the situation has developed in a direction out of control.
The day Xuanyuan Sword Shadow appeared.
Eleven top aristocratic families, thirteen top sects, as well as aristocratic sects from various provinces and many casual cultivators came to Xuanyuan's Tomb.
The Canglong Guards also realized the seriousness of the situation, and the Tiger King and Snake King escaped and arrived.
In front of the underground ancient city, a large number of warriors gathered.
But no one steps in easily.
"Mr. Zhang, if we gather the power of so many people, can we break this Xuantiandu Evil Formation?"
Tiger King asked.
"No way!"
Zhang Tianfeng shook his head. The formation that has been running for thousands of years, not to mention these people, can't be broken even if the golden elixir cultivators come. Maybe the strong ones in the Nascent Soul realm can barely try.
At this moment, a cluster of golden light suddenly erupted in the center of the underground ancient city. Then, three fist-sized pills appeared in the sky above the ancient city, and a refreshing fragrance emanated.
"The elixir of immortality is mine!"
A warrior's eyes were red, and he turned into an afterimage and rushed towards the underground ancient city.
