"Tsk, it's really the biggest in the world, and there are no surprises. ”

Fengyun looked at the stone in his hand that had become many times larger because it was cut by himself, and couldn't help but show a surprised expression.

He thought for a moment, shoved the stone in his hand into his bosom, and then took another piece from the rock wall and cut it with his knife again.

He wanted to see if the glowing stones, which were tightly bound to the rock wall, had the property of becoming larger when they were cut.

At the same time, he also wanted to see some of the details of the glowing stone in the process of getting bigger.

"Boom!"

With a soft sound that could only be caught by the hearing of Fengyun, the stone in his hand was split in two by the blade, and immediately after, it grew in size many times, and almost exceeded the grasp of his palm.

The glowing stone he had snapped down from the rock wall this time was much larger than the last time.

Even if he had already expected the result, Fengyun still couldn't help but shake his head, after all, such a thing as a stone getting bigger was amazing, if he hadn't seen it with his own eyes, I'm afraid it would be hard to believe.

However, his face soon showed a look of disappointment again, as his attempt to find out the truth about the size of the glowing stone had failed.

Even if he has worked hard, even if his eyesight is extremely outstanding, he just sees the stone getting bigger, and in the whole process, there is something similar to the magnified lens that he has seen in film and television dramas that need to focus on details, except for being faster, there is no other valuable discovery.

The disappointment didn't stay on Fengyun's face for long, and it quickly disappeared.

In fact, he had already expected such a result, after all, it was amazing that the glowing stone would grow out of thin air after being destroyed.

If he could discover its secrets just by looking at it, he would have a hard time accepting it.

In addition, he did not forget that the purpose of his trip was to find out the cause of the abnormal amount of pure qi in the spring water, and he had not yet gained anything.

"Could it have something to do with these glowing stones?"

Because the glowing stone left too much impression on Fengyun, he couldn't help but associate it, but he quickly vetoed it himself.

In order to find out the secret of the glowing stone, Fengyun not only saw it with his eyes in the process of cutting it open with a knife, but also released his perception and wrapped it.

Although the results did not satisfy him, he was able to confirm that nothing was released as the stone grew larger.

If these glowing stones have something to do with the abnormal amount of clear air in the spring water, the most likely property is that they contain clear air, and it is likely that the amount of clear air contained will be quite high.

However, if they contained a large amount of pure qi, then when he cut them open, it would be impossible for a little clear qi to leak out.

"Well, that's not right. It is also not normal for these stones not to release clear air. ”

Fengyun suddenly realized that something was wrong.

Since the content of pure qi in the spring water is so high, and these glowing stones are also in close contact with the water, it is impossible for them not to be infected by the pure qi for a long time.

In other words, under normal circumstances, after the luminous stone was cut open by him with a knife, it was equivalent to destroying its structure, and there should be some clear air leaking out.

He cut open the glowing stone, but he didn't find anything clear, which was obviously abnormal.

To confirm this, Fengyun then conducted two more tests.

At one time, he still grabbed a glowing stone from the rock wall and cut it open, completely indistinguishable from the experiments he had conducted before.

He did this to make sure that the result he had observed before, that the glowing stone had not been released after it had been cut.

The results did not change, and no trace of Qingqi was found during the process of cutting the stone and for some time afterward.

Then he did another experiment, and he also cut the stone, but this time he cut through the ordinary stone that made up the rock wall.

The result was also consistent with his previous speculation, that its structure was destroyed, that is, after it was cut, there was indeed a clear air leaking out. Although the amount was not large, through his perception, he confirmed the existence of Qingqi.

"What's the secret of these glowing stones?"

Fengyun has become more attentive to the stones clinging to the rock face.

In fact, he just doesn't want to pay attention to them, and it's hard to do it.

As he descended deeper, the glowing stones on the rock walls became more and more numerous, even beginning to join in patches, and at the same time, they grew in size.

So far, he'd seen fist-sized individuals, and if nothing else, there should be bigger ones.

The number of stones has increased, the size has increased, and the brightness has naturally increased. So, even though Fengyun is now at a deeper and deeper point under the water, the view is getting better.

Fengyun felt that he had been placed in a light, and even if his eyesight was the same as that of ordinary people, he could see everything around him very clearly.

It was precisely because of this that Fengyun's heart fluctuated, as he found that he had not even reached the bottom of the waterhole, and he had not even been able to see it.

Looking down at the waterhole, Fengyun even had the illusion that he would never reach its bottom.

Of course, Fengyun is not an easy person to give up.

With no view of the bottom of the pool, and without really shaking his resolve to find out, he decided to continue diving.

But as time passed, there was a problem in front of him, and he still had to solve it, and that was the problem of water pressure.

The deeper he dived, the more pressure he encountered.

If he doesn't solve the pressure problem, there is a good chance that he won't be able to make it to the bottom of the pool, because the increasing pressure of the water has put him to the test.

Although his physical fitness is very good, and he will not be bothered by water pressure for the time being, at least it will not hurt him, but his body's endurance is not unlimited, and once it exceeds the limit, his body will not be able to stand it.

At that time, it will be very difficult for him to continue to dive, even to ensure that he does not have problems.

After a while, a blue light came out of Fengyun's body, reflecting the water on him blue, no, the water was not reflected in blue, but really turned blue.

The blue light that emerged from Fengyun's body had merged with the water around his body.

Just as the water around Fengyun's body turned blue, his expression began to lighten, and he could feel that the pressure of the water on him had greatly decreased.
