Chapter 4021 (1/2)

”Boom

There was another terrible shock on the ground.

This time, the force of the shock spread further and deeper. Although Tang long had tried his best to sink to the bottom of the earth, he was still affected again.

At this time, he had even suffered some internal injuries, and his heart was more and more frightened: ”the fighting power of the wild ghosts and beasts has reached the advanced level of the emperor of heaven!”

After sinking to more than 200 meters on the ground, Tang long could not feel any danger, so he went to the distance.

Because he was afraid of being found by the wild ghost beast on the ground, Tang Long is also very cautious now.

It's been an hour before I know it.

Tang Long knew that he must have been a long way away from the ghost beast. If he came back to the ground again, he would not see the ghost beast again.

But he didn't come back to the ground.

After all, Tang Long was not familiar with the art of Tu dun. At this time, he continued to use it. He wanted to take advantage of this opportunity to get familiar with it.

And he was still a little worried that he would see the wild ghost again.

The war power of the wild ghost beast is too terrible.

After another hour of watching, Tang Long became more and more proficient in the use of the art of earth hiding. Moreover, under the condition of constantly using the art of earth hiding, his vitality was also greatly consumed.

”It should be absolutely safe now.”

Tang long thought in his mind that he was going to go towards the ground, but suddenly, he felt his front. In the deep of the earth, there was a powerful energy barrier blocking his progress under the ground.

The energy contained in this energy barrier is very strong, which obviously covers a place in front of Tang Long completely.

Under the barrier of this energy barrier, even if Tang long can escape from the earth, it is impossible to get through the energy barrier and reach the other side of the energy barrier.

And the defense power of this energy barrier is obviously very strong.

Even if it is Tang long at this time, it is completely impossible to destroy this energy barrier.

”It's strange that there is an energy barrier deep in the earth. I don't know what is in the energy barrier. Is there any grand building with powerful array on the ground here?”

”I might as well go to the ground and have a look!”

Tang long thought in his mind that he had already made a decision.

At this time, he was more than 200 meters deep under the ground.

Using the skill of earth hiding, he went up to the ground, and after about 150 meters, he could reach the ground. But at this time, there was no energy barrier in front of him!

”This energy barrier is obviously buried deep underground, and it is actually buried 50 meters deep. What is this place?”

”Is it a buried ancient site?”

”However, if it is an ancient site left by a very powerful person, it is unnecessary to bury it in such a deep underground place. Wouldn't it be more convenient to open up a different space directly?”

”If it is not the ruins left by the strong, how can the energy contained in the energy barrier be so powerful that even my strength at this time can not be destroyed!”

”What's going to be in the energy barrier?”

Tang Long curiously thought about it and explored around the energy barrier.

Soon, he found out that this was obviously a circular energy barrier. The circular energy barrier was very large and covered a large part of the deep underground completely.

The diameter of this energy barrier is more than 10000 meters!

”I have to study it carefully!”

Tang long thought in his mind that he was already heading for the ground. He wanted to see where this was.

He was soon above the ground.
