There are many legends in the dream world about the dream world, according to what Hong Xiaohong saw in the "Tianyuan Secret Classic", there are two main ones, one is that the great river is the starting point of all life, and the heavenly clan and the dragon clan are born from this, and the other is that the great river is the end of the universe, and neither gods nor demons can escape the sanction of death. Both of these statements are very profound, because there are very few people who can reach the dream spirit realm and retain the memories of the dream spirit realm, so the books of the Celestial Clan cannot give specific evidence.

The purpose of the white worm's dream this time was to take Hong Xiaohong to the bottom of the Great River Plain, which was about two thousand meters deep. Hong Xiaohong, who was wearing a simple swimsuit, didn't think of so much, she thought she was just going to catch fish, but the white worm kept taking her to dive, obviously not what she thought when she was in the Lingzhi Grassland, in order not to run out of oxygen, they could only speed up, fortunately, the water pressure below two thousand meters was not too big for any cultivated monster, and they would reach below one thousand meters in a while.

Taoism says that human beings are composed of three souls and seven souls, the so-called three souls, the heavenly soul, the earth soul, and the human soul, and the physical body is only a shell possessed by the body. People's memories and dreams belong to the three souls, and when the soul is out of the body, it may be making a long trip, or it may be shuttling through dreams. In fact, different dream worlds are connected by interconnected tunnels, and individuals sometimes go through time and space tunnels to another world and then come back, so some people may see the future in the dream world.

Sorting out the so-called "dream realm" is the foundation of the Heavenly Clan's cultivation. The last sentence in the "Preface to the Celestial Race's Basic Solution" reads. Basically everything in the dream world can be brought to the present world, but the "Tian Yuan Secret Codex" is unfortunately only physical, and the real reading function of this book has basically been lost in the present world in which she lives. The white worm told her that they went to the bottom of the sea to find external resources for cultivation, and when the resources were found, she would have to study the secret book in the dream world every day, and then it would be easy. Looking at the appearance of the white bug, this external resource should be difficult to find.

It is difficult for people to stand in the water, because the water has pressure on people, many people see the attitude of divers diving and think it is "slow motion", in fact, it is difficult for people to dive even with the help of external forces when they reach a certain depth, because the forces in the water are everywhere, especially buoyancy, which makes it difficult for people to sink. Under the leadership of the white bug, Hong Xiaohong, who grew up in the demon world since she was a child, reached the bottom of the two-thousand-meter-deep river with her own energy for the first time, and it can only be said that fortunately she is not a pure mortal. Later, Hong Xiaohong read the "Tianyuan Secret Classic" in the dream world, and she suddenly thought that the person who gave her this book was not originally a hidden immortal, maybe she was just a traveler who came to Hong Xiaohong's dream from a certain time and space, and she might be having the same dream with Hong Xiaohong on an asteroid in the same universe as her, and gave Hong Xiaohong a book she had read.

"Here we are." The white bugs glanced at the pressure test table stored in the small world, and the water depth they were in was automatically calculated, two, three, two, two. Its oxygen spirit balloon is as strong as a crystal glass ball, but the dive is very oxygen-intensive, it is estimated that it can only search underwater for an hour, everything depends on the will of God, before gathering an oxygen spirit balloon, it must find a spirit plant grassland.

"How do I find it?" Hong Xiaohong suddenly felt very strange, since she was looking for something, she could find it alone and put it in a Qiankun bag, obviously this matter was beyond her imagination.
