When Lin Feng woke up, Lin Xiaobao and Dong Wu were not around. The room he was in was a very ordinary inn-style room. You could hear the sound of people coming and going outside. I felt that there was no problem with his body, so Lin Feng got up and thought to go outside to take a look.

The feeling of emptiness in the body is very strong, and the large amount of energy consumed cannot be filled in a short period of time. Even if Lin Feng himself can naturally absorb the energy around him, the energy from the underground world can actively enter the body. However, these two methods cannot completely compensate for the energy. Lin Feng himself is very powerful, and it will take at least a few days to make up for the gap in his body.

There is an open corridor outside the room, and opposite the room is a large pit. In the underground world, pits are rare. Inns can be built around the pits, Lin Feng knew that there was only one inn, a hotel called "Watching". This inn is the largest inn in the underground world. Last time Lin Feng came to the underground world, he lived in another place because he didn't have enough money. As for this time, it should be the place Lin Xiaobao was looking for.

The underground world is different from the earthly world. The people here are very different from the earthly people. Moreover, the currency here is different from the earthly world. Before I fell into a coma, I just said how to get to the underground world, and did not say how to live and communicate here.

Only Lin Xiaobao can know the situation of the underground world and the living conditions here. His three brothers have visited the underground world, and they have committed sins here. The Gate of Darkness must have something to do with their three brothers. If they know the situation of the underground world, then Lin Xiaobao will also know.

When he was at Tianqi Base, Lin Feng suspected that Lin Xiaobao knew about the three brothers of the Lin family. When Lin Xiaobao admitted it, Lin Feng knew that what he knew was definitely not these. Perhaps Lin Xiaobao had been to the underground world because he was curious, so he was not surprised at the current situation.

The pit in front of you is the only pit in the underground world. I don’t know how deep this pit is. This pit has existed since Agula’s time. People in the underground world do not know the source and use of this pit, but know that it has no bottom and can make the surrounding air very comfortable all year round and regulate people’s health.

As a result, many houses were built around the pit. Gradually, the surrounding houses were acquired by powerful people in the underground world, and they knew that they had become the largest inn in the underground world.

"It's a pity that I didn't come last time. Why didn't I find such a big clue?"

Lin Feng stood next to the pit and felt a very comfortable feeling. It was a fluctuation that was not energy emitted from this pit, but a fluctuation formed by invisible ions. It was transmitted from the pit and absorbed by Lin Feng's body, and the acupuncture all over Lin Feng also had a faint reaction.

Lin Feng dreamed of some scenes in his coma, the red sun and the real sun that had weakened on the earth. These two seem to have nothing to do with each other, but since Lin Feng dreamed, he must know that it was related.

The fluctuations emitted by the deep pit are a strange thing. It is not energy, but this feeling is stronger than energy. After Lin Feng's body absorbs this fluctuation, the acupuncture points on his body undergo a slight change. The acupuncture points that have been opened and closed. All meridians in the body operate on their own without energy stimulation.

The meridians without energy support cannot transmit energy, but now the remaining energy in Lin Feng's body is very sparse, which is not enough to allow the meridians in the whole body to flow energy. However, this unprecedented fluctuation actually causes the meridians in Lin Feng's body to generate energy and transmit energy. This kind of thing has never been seen before.

Particles refer to the smallest component of matter that can exist in a free state. The earliest particles discovered were atoms, electrons and protons. Later, neutrons were discovered and confirmed that atoms were composed of electrons, protons and neutrons. They were more and more basic components of matter than atoms, so they were called elementary particles. Later, more than hundreds of these particles were discovered, and there were still a tendency to increase. In addition, some of these particles had no internal structures in experiments so far, and some particle experiments showed obvious internal structures. It seems that these particles do not belong to the same level, so the term elementary particles has become history and is now collectively called particles. Particles are not actually existing like neutrons and protons, but their collective name.

There are interactions between particles. All particle structures of matter currently understood have strong interactions, electromagnetic interactions, weak interactions and gravitational interactions, among which gravitational interactions are very weak and can be ignored.

Through these interactions, new particles may occur or particle transformation phenomena such as particle decay.

Leptons, particles that do not directly participate in strong effects and can directly participate in electromagnetic and weak effects, have been found such as electrons and their antiparticles.

Hadrons are particles that directly participate in strong actions and also participate in electromagnetic actions and weak actions. Among them, the hasrons whose spins are integers are called mesons, and the hasrons whose spins are semi-integrals are called baryons. There are many numbers of hasrons, most of which are particles that decay through strong actions. They have very short lifespans and are unstable particles, also called resonant states.

Lepton behaves like point particles and does not show internal structure, while hasrons are shown to be composite particles with certain structure. According to the view of modern particle physics, mesons are composed of a pair of positive and negative quarks, and baryons are composed of 3 quarks. Leptons and quarks belong to the same level.

What Lin Feng felt was a kind of lepton. He interacted with the original electrons and anti-electrons in Lin Feng's body, and stimulated the expansion of energy while the electrons interacted with the anti-electrons, so he could generate energy conversion and flow without energy.

"This pit is really interesting. It can also emit leptons, which sounds a bit like light ions."

Lin Feng absorbed the particle waves from the deep pit, his body gradually improved, his somewhat empty steps became steady, and the energy lost on his body was slowly recovering. The effect of this particle wave is more effective than the red light of the underground world. If he lives here, he can replenish all the energy he lost in less than three days.

At this time, Dong Wu and Lin Xiaobao came back with a lot of food. When they saw Lin Feng standing at the door, they all happily went forward to hug them. When Lin Feng saw them, his heart slowly let go.
