The wind came down a faintly visible loess path up the hill, and it took an hour to explore the area. The surface of this hill is yellow, lifeless, and there is no construction, it is a barren mountain. There is a cave in the shade on the north side of the hill, but in front of it is a pool of deep water, and there is no path to get in. Feng Lai thought that if he could fly in the sky like Li Ye, he might be able to go in.

In fact, Feng Lai didn't know that the water in this cave pool is not ordinary water, this water is called heavy water, not only the water itself is extremely corrosive, anything will disappear without three breaths, and any creature that wants to fly over the waterhole will feel an unbearable gravity, either not squeezing the body and dying, or falling into the water to be eroded.

Heavy water is extremely rare, and generally only appears in ancient places, and it should be that senior who moved from other places. The wind came to see the whole hill and there was such a cave in front of him, and it was estimated that all the treasures were in the cave.

Feng Lai took out the stone token from his arms and slowly injected spiritual power, the token suddenly became black, and the heavy water in the pool was churning, and the water pool was surrounded by dust, Feng Lai only felt that the whole ground was shaking from side to side, and the dust choked his tears.

Feng Lai swayed left and right in mid-air with his hand, and after the yellow sand smoke and dust landed, an earthen bridge spanned the surface of the deep pool of heavy water. The loess bridge deck is extremely narrow, just enough for one person to walk, and the bridge deck is full of several cracks, giving people a feeling that it is not extremely solid.

Although he didn't know the horror of the heavy water, Feng Lai didn't want to fall into the water and get soaked, so he stepped on the bridge with his left foot, stepped on it a few times, and only moved his other foot after making sure it was strong enough, and then moved forward slowly step by step, and arrived at the entrance of the cave without danger.

As soon as Feng Lai entered the cave, he saw a stone platform with a green gourd on it, and a note pressed under the gourd, on which was written a single word "drink".

He took the gourd and pulled out the plug, and the wind came to put it in his nose and smelled it, but there was no smell, he lifted the gourd and poured only the liquid into his mouth, and the liquid in the gourd was colorless and tasteless, as if it were water. Fenglai didn't delve into the matter, and continued to move forward after putting the gourd back in its place.

Walking through the narrow corridor, Feng Lai came to a lobby with a few tables and chairs, which was a very simple place to meet guests. A faint aroma fills the air. Feng Lai looked a little and found that there was an incense burner in the center of a table of eight immortals in front of the lobby, and blue-white smoke rose out of the prismatic hole on the surface of the incense burner, and then the shape broke and dissipated, blending into the air without a trace.

Feng Lai walked around the lobby and found that it connected four stone rooms, Feng Lai used the tokens in his hand to break their respective prohibitions in turn, went in and explored briefly, and probably learned that the three rooms contained pills, classics, and magic weapons. There is also a pool inside a stone chamber, and the water inside is as clear as a hanging mirror. I don't know what it's for.

After briefly familiarizing himself with the cave, Feng Lai thought that he knew very little about this cultivation realm, and he should start from all kinds of classics. The wind came to the stone room where the books were stored, and there were many wooden compartments in the stone room, and a bamboo slip was placed in each compartment. Feng Lai opened the first prohibition with the token in his hand, took out the bamboo slips and glanced at them one by one, the first bamboo slips recorded some matters, as if to tell the people who came to this cave later.

According to this bamboo slip, this Fang Dong Mansion will only belong to the disciple who comes here in a few years, and the disciple who comes here needs to concentrate on cultivating to the realm of the Yuan Shen, and then go to a foreign place to complete a matter to repay the kindness of this master and apprentice. The books in this stone chamber are progressive, and the next floor can only be opened if the requirements of the previous layer are met.

......

The bamboo slip is a contract at the end, which needs to be signed by the comer with blood, and if the content of the contract is violated, the signatory will suffer from the disaster of heart demons and bones, and all the Dao fruits will be destroyed. Feng Lai held the bamboo slip in his left hand, put the index finger of his right hand between the fingers and bit it in his mouth, the red blood slowly ooped out, condensed into a small ball between the fingers, Feng Lai flipped his hand over, so that the blood dripped on the contract.

The handwriting on the contract instantly melted into a pitch-black mass of ink that surrounded the blood of the wind, and then spread from the ink in all directions, and the silky thick ink thread plunged into the blood ball, and within five breaths, the blood ball became larger and larger, and the color turned red and black, and then the black ball broke open again, and the ink sprinkled on the bamboo slips, reforming the number.

The wind came to look at the bamboo slips again, and now it is presented with an exercise, called the Five Elements Recipe. As the name suggests, these five elements are based on the cultivation of the five elements. But Feng Lai couldn't help but wonder, they all said that the best spiritual root of a single attribute is the easiest to cultivate, and wouldn't it be a fool's dream to practice the five elements spiritual root together?

The last text of the bamboo slip answers the doubts of the wind, the bamboo slip explains, the world is greedy for speed, thinking that a single spiritual root belongs to the superior qualification of cultivating immortals, in fact, the cycle of heavenly principles, all things are born together, the pursuit of a single ultimate will only be a catastrophe, throughout the ages, there are countless people with a single attribute of the best spiritual root, or reach the realm of the Yuan Shen, or reach the realm of Mahayana, but no one has entered the catastrophe.

The world does not know the reason, the old man coincidentally entered an ancient fairyland to find this five elements of life, but know one or two, now the Tao has been completed, can not start again, have to hope that someone can break through the catastrophe, rescue us and other monks, and return the world to a mess.

The wind came to close the bamboo slips, and I probably understood the seven-seven-eighty-eight in my heart. These Five Elements Spiritual Root seems to be a mortal, but in fact the number is very small, and it is rare to have one of them among ten thousand people, and it just so happens that Feng Lai is this body. In previous years, the Five Elements Spiritual Root was spurned by others, and the people who belonged to the lower classes of the cultivation realm, no matter what kind of attribute they practiced, they could not succeed, and they were slowly forgotten.

Feng Lai silently recited the Five Elements in his heart, and after confirming that he had memorized it, he put down the bamboo slips and came to the stone room with a waterhole. According to Zhu Jian, this pool is the place where the practice rests on weekdays, and this water gushes from the underground spiritual veins, and the spiritual energy is pure, which can increase the speed of cultivation.

Feng Lai took off his clothes, entered the pool to soak, in the moment the wind came into the pool water, a warm feeling hit the whole body, the original fatigue swept away, Feng Lai only felt comfortable, full of energy.

When you close your eyes, you can clearly feel the aura flowing through the body as the water passes over your skin, slowly running along the meridians of your body. Feng Lai tried to use his mind to guide the flow of aura, and after many attempts, he had obvious results. As long as Feng Lai's mind moves, the aura in the body will flow with the trend, and Feng Lai feels that the aura is like a part of his own body, which can be commanded by people.
