Su Ming did a warm up by the waterhole for a while, and tried it a few times before jumping into the waterhole and swimming down.

Swimming is not difficult for Su Ming, he has been able to swim since he was a child, and his water ability is not bad, especially when he cultivates the Rock Heart Method, he can do a good job of kicking the water and hitting the water.

But it was the first time to dive, and as the body dived in the water, the pressure of the water pressure on the eardrum made the eardrum feel a slight pain.

Su Ming went down four or five meters along the mountain wall, the wall of the cave entrance was still not touched, he touched it along the way, but found nothing, just wanted to continue diving, and found that his ear hurt badly, it was really uncomfortable, and even his chest was slightly depressed, as if he was pressing a boulder, he had to float to the surface.

"Whew."

Su Ming sat on the shore, patted his head, patted the water in his ears, and relieved it for a while before his ears became comfortable.

A depth of ten meters is relatively difficult for ordinary people, and when the water reaches less than three meters, the water temperature is unbearably cold, and it is easy to cramp.

Su Ming rested on the shore for a while, poured internal force into his body, especially near his ears, to protect his eardrums, and then took a long breath and jumped down again.

Poof.

Su Ming swam towards the hole in the darkness, this time with the help of internal force, his body was much lighter, and the cold and the pressure on his ears were reduced a lot.

Su Ming groped his way down, not giving up any distance, and surfaced four or five times one after another, and finally found a cave at a position of seven or eight meters.

So Su Ming floated up and changed his breath, and took out two water bladders, one of the water bladders was emptied and held in his hands, and the other put the fire fold in the water bladder and fastened the mouth of the bag.

Su Ming picked up his sword again and carried it on his back, this sword was a sharp weapon given by his senior brother, as a reward for using himself that time, it was indestructible, and naturally it could not be discarded at will.

Then he took a deep breath and jumped into the water at the nearest position, swimming deeper into the pool.

came to the entrance of the cave again, but in just twenty seconds, Su Ming swam inside with a cat's waist.

The dark cave has no light at all, and the cold water around it makes people feel like they have fallen into an ice cave, even if they have internal strength.

In this dark environment, the breath in Su Ming's mouth was consumed quickly, and after swimming a distance, Su Ming couldn't hold on any longer, put the water bladder to his mouth, squeezed the water bladder violently, and squeezed all the air into his mouth.

After Su Ming finished sucking, he pinched the mouth of the bag, but he didn't know whether to continue forward or go back.

The support time is less than half as expected, and the gas in the bag can only support one mouthful, in case the back journey is relatively long, and you run out of that breath, it is estimated that you will not be able to come back.

But now that he has arrived here, Su Ming is not willing to give up like this.

He planned to swim only this breath in his mouth, and the next time he used the water bladder to ventilate, he would come back immediately.

Su Ming continued to swim forward, and after his body had advanced for a distance, he vaguely felt that the passage was floating.

Before he ran out of energy, he popped into a large pool, then slowly swam upwards before finally jumping out of the water.

Crash.

Su Ming's head came out of the water, he exhaled heavily, and he gasped for a while before he had the strength to look around.

The place that entered the eye was a somewhat dim cave, although the cave was dark, but it was not impossible to see at all, there were several small holes above the cave, the largest was the size of a palm, and the sunlight shone down, with the help of these pillars of light, Su Mingmo vaguely saw the surrounding scene clearly, and found the entrance to the ancient tomb.

Su Ming swam towards the entrance of the cave, climbed ashore, and walked directly towards the cave.

The cave was getting darker and darker, Su Ming took out the fire fold from the empty water bladder, opened the lid, blew it on fire, and then entered with the help of a faint red light.

The cave was long and narrow, and there were places where Su Ming needed to bend his waist, and after walking more than ten meters, Su Ming entered a huge stone room.

Su Ming groped around the wall and found the torches left behind, and after Su Ming lit them with a fire fold, the room began to brighten.

With the help of the light of the flames, Su Ming searched for the Nine Yin True Scripture, and found many small characters and pictures on the top of the stone room, and there were four big characters on the right, the Nine Yin True Scripture.

In addition to the cheats of the Nine Yin True Scripture, there are also the secrets of the entire ancient tomb.

This is left by Wang Chongyang when he built the ancient tomb, and later gave the ancient tomb to Lin Chaoying, who did not know where it was.

It wasn't until seventeen years later, when Xiaolongnu was twenty years old and Yang was sixteen years old, that they strayed into this place under Li Mochou's persecution.

However, at this time, Xiaolongnu is only three years old, Yang Guo has not yet been born, the story has not yet begun, and maybe there will never be a beginning.

With the help of the light of the torch, Su Ming browsed the moments above word by word, and after reading it, Su Ming couldn't wait to cultivate.

Su Ming first chose the Book of Changes Forging Bones, this martial art helped him a lot, I Ching Forging Bones, you can also cultivate internal strength, this martial art is only slightly inferior to Shaolin's peerless internal strength Yi Jin Jing.

Although he has the internal strength of the rock, it is not a big problem to cultivate the I Ching Bone Forging Chapter.

In the original work, most of the people who practiced the I Ching Bone Forging Chapter and even the General Outline were already burdened with internal strength.

For example, Guo Jing and Zhou Botong who have true internal strength, Yi Deng who learns innate skills, Hong Qigong who has other internal forces, and so on.

Therefore, the I Ching Forging Bone Chapter will not conflict with the original internal force.

Su Ming wrote down the content of the I Ching Bone Forging Chapter, ran the internal force according to the above operation mode, identified the acupoints, and meditated secretly, and after a while, the nine yin internal force emerged from the dantian, circulating in the body, and the momentum was huge, washing the meridians, refining the bones, making the meridians wider, and making the bones tougher.

A week later, the internal force returned to the dantian and merged with the Rock Heart Method to become one.

The twelve canons, the eight meridians, and the bones of the body all change under the action of internal forces. Su Ming only felt the itching of his muscles and bones, and streams of heat swayed in his body, making his body slowly change.

Su Ming spent two hours, memorizing the meridian acupoints and running routes, while carefully running in his body for twenty weeks. I only feel that my body is warm, and the internal force in my body has increased a little, which is much faster than before.

After twenty weeks, Su Ming had memorized all the meridian acupoint routes.

He stood up, picked up the torch, and continued to watch the rest of the martial arts.

Su Ming endured hunger and stayed in the secret room for three or four hours, mastering the secret method of holding qi and the secret of solving acupoints first.

This secret method of holding breath can just help Su Ming ventilate without the help of a water bladder.

And this secret solution to the acupoint can not only unlock the acupoint by itself, but also allow people to unravel the true qi in the body when they go crazy, which is a powerful martial art and plays a huge role in actual combat.

After Su Ming learned, he felt empty in his stomach, and he was really hungry.

Su Ming planned to leave the stone room first, anyway, he had already found a place, and it would be easier to come next time.

Su Ming had this idea, extinguished the torch, left the stone chamber, and then jumped into the pool, with the help of the secret method of holding his breath, he dived into the waterway and successfully returned to the outside of the ancient tomb.

Su Ming came out of the water, climbed up the waterhole with his hands and feet, and went to find his clothes, but after walking around, he found that his clothes and all his belongings were gone.

Where's my clothes?
