Theoretically speaking, Han Sanqian should be very disappointed, or almost ready to leave here.

Because it was too deep, Su Yingxia was actually unlikely to go inside anymore. The reason was also very simple. As mentioned earlier, if the inside collapsed, there was a high possibility of being buried alive.

But the problem is, that strange sound appears again...

Da da da.

Compared with before, the sound this time was obviously heavier. Moreover, the frequency is also three, not one.

All this shows that there is indeed something inside.

Therefore, Han Sanqian not only could not leave, but also had to bite the bullet and go deeper.

However, compared to the beginning, Han Sanqian was still on guard, but his speed was significantly faster.

Since there is something inside, it is very necessary to rush in as quickly as possible to see what is going on.

A few minutes later, Han Sanqian had gone several hundred meters deeper inside.

If Han Sanqian had previously felt that there might be several thousand meters of depth here, then as Han Sanqian continued to go deeper, he even began to feel that his initial judgment was actually very wrong.

Judging from the current trend, this depth is very likely to be at least doubled.

Yes, in a straight line, it is impossible for the diameter of this hill to be such a long distance.

Therefore, there are only three possibilities. Either the cave goes all the way deep underground, or the cave takes on an infinite S shape in the hills.

Or the last possibility is an S-shape that can extend the length infinitely deeper and all the way down.

If interlaced in this way, the entire cave may even reach thousands of meters, or even more.

Han Sanqian walked inside for about ten minutes. The further he walked, the colder his heart became, because the chance of the third possibility became greater.

This means that Han Sanqian will need more time if he wants to truly explore the cave.

The key point is that if there is any danger inside, it may become more dangerous and difficult for Han Sanqian.

After all, at that time, Han Sanqian wanted to escape and retreat, but given the terrain, he had to run outside for a long time.

Fortunately, it was not as hot inside the cave as expected, nor was it cold and biting caused by humidity.

Along the way, Han Sanqian at least did not feel any physical discomfort.

Therefore, Han Sanqian was not idle. He began to expand his spiritual consciousness in his body, and after sensing no danger along the way, he could not help but speed up his steps.

After walking inside for about ten minutes, Han Sanqian gradually began to discover a pattern. JrNovels.com
