"No?"

"It stands to reason that there must be a spiritual vein underground, a spiritual vein that extends from the center of the earth, and it just happens that the groundwater flows through the spiritual vein, so it creates a spiritual spring. But there is no groundwater coming up, where does the water come from in this cold pool?"

Liu Shenghan said: "The water in the cold pool flows down from the stone cliff on the water. ”

"In that case, there is no spiritual vein under this mountain, because only groundwater can pour spiritual power into the cold pool, and it will dissipate into the air as soon as it comes out of the ground, so it is impossible for surface water to have spiritual power. Shenghan, we are all wrong about the formation of this cold pool, not because of the underground spiritual veins, there must be another reason. ”

"I'll probe it. ”

Liu Shenghan went to the bottom of the water again and touched the bottom for most of the day.

Liu Shenghan did not let go of any corner, and after several hours of exploration, Liu Shenghan finally found that this cold pool was not naturally formed, it was artificially caused, because the bottom of the cold pool was a large stone slab. Liu Shenghan groped for a long time, and felt that there was a hole under the big stone slab at the bottom of the cold pool. The function of this cold pool must be to hide the hole underneath.

Liu Shenghan immediately drilled a small hole in the bottom of the water.

"Whoa!" With a bang, the water of the cold pool seeped down from the small hole, as if the pool had been released, and the water level on the surface of the cold pool immediately dropped.

"Sure enough, there is a hollow under this cold pool!"

Liu Shenghan immediately drilled down from the hole under the water, and after drilling down, Liu Shenghan covered the stone slab that had just been smashed open, otherwise the water of the entire Hantan would be light, and if the Hantan was out of water, the bottom of the water would be found at once.

"Bang!" Liu Shenghan jumped.

At the bottom of this cold pool, there is a sealed space four meters high.

Liu Shenghan immediately activated the Great Demon Dragon's dark internal strength, and the darkness suddenly became like daytime, and Liu Shenghan could see clearly.

"Wow, it's a sealed space about five meters long and wide, four meters high, and the ceiling is the bottom of that cold pool. Liu Shenghan could hear the sound of running water in the cold pool overhead.

Tongling Baoyu said: "The cold pool above the head is not caused by the spiritual veins, it must be caused by the sealed space underneath." ”

Liu Shenghan glanced at the cold pool, there were sealed stone slabs all around, including the ceiling overhead, but the ceiling had been smashed out of a hole by Liu Shenghan, although the stone slab at the entrance of the cave was moved back to cover it, but there was still a lot of water flowing down.

The entire sealed space was extremely cold, far colder than the cold pool above.

Yanagi touched the stone wall, because there were no items placed in the sealed space.

At this time, Tongling Baoyu said: "Sheng Han, look at the stone wall, the slightest bit of text is regular, not the stone lines, but the enlarged tadpole text." ”

"Ah! it's Tadpole Wen. Liu Shenghan only found out after being reminded by Baoyu.

"Yes, the tadpole text you have seen before is small, so you can distinguish it, but here, a tadpole text is magnified several times, so if you don't look at it carefully, you think it is the texture of the stone wall.

Liu Shenghan immediately read those tadpole texts.

Baoyu said: "This tadpole is a kind of martial arts. It's called "A Knife". ”

Liu Shenghan nodded, Liu Shenghan can understand the tadpole text, nine times out of ten it is because of Baoyu, because Baoyu can see it, Liu Shenghan can naturally understand it.

"Sure enough, it's a kind of martial arts, and the name is very simple, a knife. ”

Soon, Liu Shenghan read all the tadpole texts and memorized them in his mind.

"It's cold, then let's practice!"

"Okay!" Liu Shenghan was also very excited.

The opening text of the tadpole text says: "This exercise is called a knife, and I created it by chance. The so-called one knife is to kill people with one knife and hurt people with one knife. Anything that requires a second sword is not a good exercise. ”

Liu Shenghan not only appreciates the domineering praise of the person who created this exercise, but anyone who needs a second knife is not a good exercise, and the person who can say this must be a person who is awesome and coaxed.

"This exercise is not difficult to say, it is not easy to say that it is simple, it needs to be firm-minded, strong-willed, and mentally strong, because a knife consumes too much mental power, and if you can't practice it, it is easy to hurt yourself. ”

Liu Shenghan immediately closed his eyes and began to practice.

(In order not to divulge the secret, I won't write down the cultivation method specifically here, so as not to learn to hurt people, forgive me.) ）

When Liu Shenghan opened his eyes, it had been more than half a day.

Liu Shenghan looked at the stone wall and tried to do it.

Liu Shenghan's eyes only had the stone wall in front of him, and then, the stone wall gradually shrank in Liu Shenghan's eyes, and kept shrinking, shrinking, and finally, what Liu Shenghan saw in his entire eyes was only one percent of the stone wall, that is to say, Liu Shenghan's visual range was less than 5 centimeters, just like seeing the world through a small hole of five centimeters.

And Liu Shenghan's forehead was already sweating.

When he was able to narrow down the visual range to one point, it meant that "One Knife" was practiced. Liu Shenghan killed with a knife, and hit that point in an instant, remember, it was an instant, and the opponent did not have any time to react at all, that is, a blow must be hit, as long as the knife was struck, it was a knife, so it dared to be called a knife. One knife hurts, one knife kills, and there is absolutely no need for a second knife.

"No, it still can't be condensed to one point. Liu Shenghan shook his head, suddenly relaxed, and his eyes returned to normal.

"Keep working hard, your mental power is very high, and this sword martial art is definitely a very good means of killing the enemy. ”

"Hmm!" Liu Shenghan continued to work hard, and began to focus his gaze again, so that the focus of his eyes was on one point.

Just now, Liu Shenghan could only condense to a point of five centimeters, which is far from enough, how big is the point? No one can say clearly, a point can be infinitely large or infinitely small.

"Come on!"

Two hours later, Liu Shenghan focused his gaze on a three-centimeter point.

"The lowest, it can't be lower. Liu Shenghan said that he had done his best.

At this moment, Liu Shenghan has white hair, yes, it consumes too much mental power, I am afraid that it consumes more mental energy than Gongsun Zhengqi's storm eyes.

The white-haired Liu Shenghan looked a little elegant, and the Tongling Jade instantly made Liu Shenghan's hair black.

Liu Shenghan rested for half an hour, and his spirit was restored.

Compared with internal strength, the speed of spiritual power recovery is much faster, and half an hour is enough to recover.

Liu Shenghan continued, still only condensing three centimeters of points.

Liu Shenghan wanted to test it, because there was no knife, he could only use stone chips instead, Liu Shenghan held a broken stone chip in his hand, and his eyes focused on the three-centimeter point on the stone wall in front of him.

"Huh!" Liu Shenghan shook the stone fragment, and in the blink of an eye, the gravel fragment sank into the stone wall.

"Okay, it seems that with my current ability, I can only condense to this point at most, and it seems that the power is not bad, and the hard stone is instantly submerged. If it is an opponent, I will slaughter it with a knife, and I will be slaughtered within 0.000 seconds, because it is simply a teleportation speed, even my master may not be able to dodge. Liu Shenghan said triumphantly. R1148
