His inner yin skill has broken into the second level of the dantian, so he walked into the "dead end hole" of the platform according to the method he thought before, and he wanted to rely on his own skills to turn this "dead end hole" into a "live hu hole" and open up the exit to the outside.

He walked to the bottom of the "dead end hole", mobilized the Yuan Force of his whole body, quickly raised the Inner Yin Gong to the double level of Dantian, and gathered the Yuan Force of his whole body on the small copper sword, and used the small copper sword to slash towards the rock.

Although the rock was hard, because Wang Heng'er gathered the Yuan Force on the tip of the small bronze sword, it was extremely sharp, and the rock was cut into a big hole. But this did not dig down a large chunk of the rock, and he plunged in several times, but still did not pry a single rock off, and if he continued like this, when would he be able to open the exit to the outside?

Wang Heng'er thought about it for a while, and concentrated the Yuan Force on the tip of the small bronze sword, and the contact surface with the rock was too small, which was the fundamental reason why its power was not great enough.

According to the saying of power, the inner yin gong has reached the double weight of the dantian, and its yuan force should have an impact force of 10,000 catties, so he wanted to try its strength of 10,000 catties with his fist.

He once again raised the Inner Yin Gong to the Dantian Double, gathered the Yuan Force in his right hand, and threw a punch at the rock.

His idea really worked, as soon as the fist burst out, there was a "boom" sound, the fire shone brightly, the flying stones splashed everywhere, the earth ash was full of holes, and the power appeared, and it was really shaking the mountain.

This inner yin gong dantian is double, and it does have the power of ten thousand catties, and what he said is true.

He coughed because of the dust in the hole, and he hurriedly retreated, waiting for the dust to be less, and then acted.

He retreated to the platform and saw that some of the dust washed out of the "dead end hole" had fallen on the night pearl, which made the night pearl, which was not very bright, appear even more gray, so he stretched out his hand and wiped off the dust that fell on the night pearl.

Just as he was wiping the ashes, he seemed to feel that the pearl of the night moved slightly, and he was shocked.

He stood up, looked at the Night Pearl again, and then looked at the words on the wall of the cave, and suddenly realized something.

"Speaking of which, I've been here for many days, why haven't I noticed that there is an artificial tacit understanding between the pearl and the cave wall text this night? ”

"The words on the wall of this cave are set opposite to the night pearl, and the light of the night pearl can shine on the words, what is this not artificially placed?"

"There's got to be something wrong with that!"

He seemed to have discovered the secret, and he was excited.

He thought again, when he was wiping the ashes just now, the pearl turned slightly this night, is there any mechanism set up here?

He used his hands to wrench the night pearl left and right, back and forth, trying to find something in it.

But that night, the pearl only shook slightly, and there was no other abnormality.

"The reason why the pearl can shake slightly this night may be that when I hit the 'dead end hole', the impact was too strong, and the rocks around it were cracked, which made the pearl loose this night. ”

He followed his train of thought and looked at the rocks around the Night Pearl, but didn't see any cracks.

"No, the bottom of that 'dead end hole' is a little far away from this night pearl, and the bombardment of this punch is impossible to crack the rocks here. ”

He looked left and right at the night pearl, and always felt that there was some kind of secret in the night pearl.

He no longer shook the Night Pearl back and forth from side to side, but turned it hard to the left and right.

He just gave it a try, and this night pearl can indeed turn left and right at will.

He felt more and more that this night pearl must be some kind of mechanism set up artificially, and he thought that it could break through and a miracle happen on it.

He turned from side to side several times, but saw nothing else unusual, and he was disappointed again.

"Could it be that I am thinking too much, it is due to the formation of many years of natural forces, not some artificial mechanism. ”

Once again, he was in the pang of disappointment.

He looked at the pearl of the night again and was stunned.

At this time, Wang Heng'er saw the bamboo slips on the ground next to the Night Pearl, which were also covered with thick soil ash.

"If I can't find the exit in this cave, I don't know if it's dead or alive, no matter what, this bamboo slip has enabled him to learn the three-grade martial art - Taiyu Sword Technique, and expel the toxins of the Yuan Neng Fruit, which is a great contribution to him. ”

So he squatted down and took away the ash Buddha of the bamboo slips.

"It's a pity that the Taiyu swordsmanship recorded in this bamboo slip is incomplete. Heng'er looked at the bamboo slip that had been brushed off the ashes and said in his heart.

He also arranged the bamboo slips according to their fronts.

"If you can get out of this hole, you will bring out this set of Taiyu swordsmanship and show it to the world, this lost Taiyu swordsmanship many years ago has now been found again. ”

"There is no exit from this hole, how can I go back?"

"It's better to be realistic, this night pearl is nothing special, then forget it, I'll go and bang that 'dead end' with my fist to open up a way out." ”

Just as he walked into the "dead-end hole" again, he inadvertently looked at the freshly lined bamboo slips, and he seemed to realize something, and he stopped his footwork into the "dead-end hole".

He found that the bamboo slips lying on the ground, ignoring the specific words and graphics, generally looked like a round ball, and this ball felt somewhat familiar to him.

He suddenly cried out in amazement, "Isn't this ball the pearl of the night on this platform?"

He was deeply surprised by this discovery.

"Is there a secret here?"

He looked carefully at the looming spherical diagram, and he saw that on the humanoid diagram of the Taiyu swordsmanship on the bamboo slip, the person in the picture had a move, and he happened to stand on the hidden ball, and stabbed the left side of the ball three times with his sword, and then stabbed five times to the right.

"What does that mean? There must be a mystery here. ”

"Could it be that in this picture, stabbing the sword to the left and right of the ball three times and five times respectively, implying that the "Pearl of the Night" is rotated to the left and right for three and five weeks respectively?"

He combed through the front and back of his arrival on the platform from beginning to end.

In the black hole, the night pearl is found, and the words on the cave wall should be discovered by the light of the night pearl. But he didn't do this, because the words on the wall of the cave were covered by Yuan Neng grass blades, and they were too old, a little vague, and he didn't see the words, so he recklessly ate the Yuan Neng fruit. Later, he found the text on the cave wall, so he found the bamboo slip martial arts buried under the text according to the text on the cave wall, and after arranging the bamboo slips, he found the invisible ball diagram and found the secret of the rotation of the night pearl.

He thought of this, and he thought that his reasoning must exist.

"No matter what, what you understand is right or wrong, as long as you do it according to the picture and do it once, everything can be confirmed. ”

So, according to his own understanding, he used his hand to make three circles to the left and five circles to the right of the pearl that night.

But after trying it, nothing happened.

This once again disappointed him deeply.

"Is it a misunderstanding?"

He looked at the ball on the bamboo slip in a daze, and suddenly had a new enlightenment.

"This must be to use this night pearl as a way to practice the Taiyu sword legal person, and when practicing the Taiyu swordsmanship, use the Taiyu sword to stab the night pearl three times on the left and five times on the right. ”

Thinking of this, he practiced a set of Taiyu methods from beginning to end, and used the Night Pearl as his own sword practice. In the process of practicing, he raised the Inner Yin Gong to the dantian double, and concentrated all his Yuan Force on the sword body, and the Taiyu Sword flashed bursts of Yuan Force waves. Every time he stabbed at the Night Pearl, the Night Pearl turned rapidly under the destruction of Yuan Force.

A set of Taiyu swordsmanship came down, and the sword stabbed three times to the left and five times to the right at the night pearl, and the traces really appeared.

He could only hear the sound of "yaa" in the black hole, and he felt that the ground was sinking. He felt a little nervous for a moment, but when he saw the cave wall moving upward, he realized that it was not the ground sinking, but the whole platform sinking.

He slowly descended the platform for some distance, and finally stopped with a "click" with a vibration, and the platform led him to an underground hall.
