Dongxiao Zhenren and Yan Fei stayed in the Demon Cave for three days, and left after making sure that everything was right, but Ye Quan stayed behind and stayed at the exit of the first layer with the White Tiger.

The place that guards the exit of the demon cave is also called the "Gate of Hell", which is the front line of the hidden gate guards, and there are three forks in the road further on, and the fog inside is heavy, and few people dare to go deeper.

Generally speaking, the creatures inside the demon cave fight each other, hunt for food, and also contain each other, and it is not difficult to deal with one or two occasionally scurrying out.

The most dangerous and troublesome thing is not the bloodline thorn snake, let alone the powerful individuals such as the blade mantis, flying centipede, and shadowless leopard, but a large number of giant mutant insects such as soldier ants and killer bees.

Fortunately, this level of insect tide may not occur once in a hundred years.

The "Gate of Hell" has a powerhouse of the Heavenly and Human Realm at any time, and although the White Tiger's martial arts cultivation is still half a step away from breaking through the Heavenly and Human Realm, coupled with his SS-level gold ability, it is definitely a combat power at the level of the Heavenly and Human Realm, and even surpasses it.

The reason why Ye Quan stayed, in addition to his curiosity about the Demon Cave, was also to exercise his actual combat experience and ask for advice from the White Tiger.

Ye Quan wanted to go deep into the Demon Cave to explore, but the White Tiger, who had always been not afraid of heaven and earth, dissuaded him.

Since ancient times, there have been many powerful people who have gone on expeditions, but the result can only be described as nine deaths, and in the past three hundred years, only Qinglong has been able to escape with his whole body.

In the days that followed, Ye Quan successively put hundreds of miniature smart detectors into the Demon Cave. Although he sent back a lot of valuable information, the result was that he never returned, swallowed up by all kinds of accidents and dangers. The farthest probe flew for more than 3,000 miles, but it was still unknown how deep the cave was.

In contrast, the creatures living in the cave are much more comfortable, they have a general area of activity, they do not wander around, and they seem to have an instinct to know exactly the existence of danger. It is also more adaptable to the harshest environment.

Ye Quan can't enter the space now, and without this back road, even if he has light armor, he can't guarantee 100% safety. Because the spatial rift might throw him into some unknown corner of the universe.

Ye Quan finally dispelled the idea of exploring the demon cave, but grabbed a lot of monsters and threw them into the space.

The White Tiger itself is a martial arts idiot, but also a mobile treasure trove of martial arts, with deep attainments in the martial arts of the Kunlun School, the Pure Yang School, the Natural School, the Quanzhen School, the Chaoyang Temple, the Shaolin Academy of Zen Buddhism, Xingyi, Tai Chi, Baji, Bagua and other sects. Those who ask for advice from Ye Quan do not refuse.

Ye Quan was even more inspired by the fact that the White Tiger created the White Tiger Heavenly Punishment and Beheading. Begin to combine martial arts and abilities to find your own path.

With the progress of martial arts and abilities, Ye Quan found that the two were not distinct, but had a lot in common, he was able to break through the realm of false pills, and his abilities played a great role, and the white tiger obviously took the path of integrating abilities and martial arts.

During his time in the Demon Cave, Ye Quan lived a very fulfilling life. I was only going to stay for a month or two, but five months passed in a flash.

During this time. Ye Quan rarely paid attention to the affairs of the outside world, and combined his daily movements and static, entering a state of retreat and asceticism, sometimes meditating and contemplating, comprehending the Dao, sometimes pondering and stimulating his potential alone, and sometimes learning martial arts and exchanging experiences with the white tiger.

Sometimes, Ye Quan would use his telekinesis to go deep into the demon cave, deliberately provoke all kinds of powerful monsters, lure them to the gates of hell, and then engage in a life-and-death struggle with the monsters.

The penance during this period of time was not in vain, Ye Quan completely consolidated the foundation of martial arts, his soul was flawless, his spirit was complete, his martial arts will was firm, his true qi in his body was endless, and with the help of mental power and spiritual fruit, he easily reached the realm of Fake Dan Dacheng, and the speed of progress was unprecedented, which surprised the White Tiger.

Not only martial arts, but in terms of ability, Ye Quan has already touched the mystery of the S-rank, and he only needs to take half a step to become a real big man in the ability world.

Unlike in the past, when he used space enhancement to achieve the purpose of promotion, this time Ye Quan sharpened his spiritual power in a down-to-earth manner, and through his own efforts, he moved forward step by step.

In the past six months, most of the news from the outside world has been bad, there seem to be more and more monsters in the ocean, there are frequent attacks on passing ships in various seas, and dangerous sea journeys have made many crew members reluctant to go to sea, especially in the open sea.

At the beginning of October, Ye Quan received an exciting message from Lingxi: the No. 9 expedition spacecraft had found a huge planet of life 26 times the size of the Earth 157 light-years away, and seven satellites of various sizes orbiting it.

The planet's ocean area accounts for about 60%, and the land area is divided into 12 continents, except for a small number of ice fields, plains, swamps and deserts, most of the land area is covered by lush primeval forests, and the richness of animal and plant resources far exceeds that of the earth.

Ye Quan was naturally overjoyed when he got the news, named the planet "Yanhuang Star", and asked the No. 9 spacecraft to start a comprehensive exploration of Yanhuang Star, such as whether there are intelligent races on the planet? What is the concentration of Reiki? What are the components of the atmosphere? how mineral resources are, etc.

In June last year, Ye Quan sent a total of twelve interstellar exploration spaceships with a fifth-level civilization technology level to the surrounding star fields of the solar system.

For example, spacecraft No. 4 found a golden asteroid with a diameter of more than 900 kilometers; Ship 3 found a battlefield ruin; Spaceship 7 encountered an interstellar caravan with some Level 4 civilization technology.

Ye Quan immediately issued a series of orders, so that his group began to form the next group of exploration teams, and there were only hundreds of scientific research-based biochemical humans and intelligent robots on the No. 9 expedition spacecraft, and there was no way to conduct a comprehensive and detailed exploration of a large planet.

Once it is confirmed that the conditions of Yanhuang Star are met, Ye Quan will definitely have to develop and immigrate, 157 light years is really not far away for the vast universe.

Considering that it is too expensive to exchange from space, Ye Quan plans to let Galaxy Aerospace start building a large starship, anyway, the design drawings have already been available, there is no shortage of materials, and skilled workers can use robots.

Of course, the manufacturing is only the hull part of the spaceship, and the warp engine, weapon system, protection system and control system with higher technical requirements will be exchanged by Ye Quan from the space system, and finally assemble a starship with some fourth-level civilization technology level.

In this way, although there is no fifth-level civilization capable of space jumping, it can also enable the spacecraft to move at more than 100 times the speed of light, shortening the distance between the earth and Yanhuang Star to a year or even half a year.

The news of the discovery of the planet of life is still strictly kept secret for the time being, and only a few high-level leaders such as Lingxi, Guan Yong, Ye Zhong and Ye Guang know that this discovery is enough to be included in the top ten major events affecting human history, comparable to Columbus's discovery of the New World.

With the power of the infinite resources of the New Life Planet, coupled with Ye Quan's full promotion in technology, it is foreseeable that mankind is about to enter the age of interstellar exploration.

Ye Quan decided to end the retreat and leave the hidden door to unveil the prelude to this great era with his own hands. (To be continued......)
