This is a prehistoric civilization on the earth, and it is impossible to know in what era it appeared on the earth.

Prehistoric humans who cultivated civilization mastered the ability to strengthen themselves by absorbing cosmic energy.

The cosmic energy here Lin Chen speculated that it should be the same kind of energy as the true qi, and the name was different, but it was the same way, and it was the same energy system.

Because on the platform in the center of the cave, this device built by the prehistoric civilization is to absorb the aura in the seawater and exhale a rich aura.

Therefore, Lin Chen believes that the cosmic energy is the aura of heaven and earth.

Humans who practiced civilization in prehistory believed that the purpose of cultivation was to strengthen the body and prolong life.

They succeeded in achieving these two goals through their cultivation.

Each of them is very physical.

Their average age is around 130 years old, and the longest to live can reach more than 300 years.

The average age is around 130 years old, and the longest to live can reach 300 years old.

This message told Lin Chen something.

The cultivation methods of prehistoric human beings who cultivated civilization did not become a set of cultivation systems, but simply absorbed cosmic energy into the body to strengthen physical fitness, improve and promote the activity of body cells, and increase life expectancy.

In fact, this step can be done by many modern Qi practitioners.

It does work.

It is divided according to the level of practice.

Although it is said to be the cultivation of civilization, but only by cultivation, everyone runs to practice, and the society will never progress, and it will never develop into a civilization.

What they are most proud of is that their use of cosmic energy has reached the pinnacle, also known as energy civilization

They discovered in nature a mineral capable of storing cosmic energy.

The power stone is the crystal that Lin Chen found in the underground rock layer, and the colorless and transparent power stone is the power stone that has just been mined.

A power stone is a type of container. A container for storing cosmic energy.

The freshly mined colorless and transparent gemstone is an empty container.

A colored energy stone is a container filled with cosmic energy.

The gemstone is as flawless as it is done. Transparency. The hardness and size of the quality are divided into several grades, which are divided into low, medium, and high.

There is a big difference in the amount of energy that each level of power stone can store.

The low-grade energy stone contains a lot of impurities, and the volume is relatively small, the small one is about the size of a soybean, and the large one is the size of a flower bean and rice. The amount of cosmic energy that these gemstones can store is very limited.

The high-grade power stone is pure and flawless, very large, and the crystal particles inside the power stone are more reasonable and tighter, and the cosmic energy that can be stored is very large.

The aura is in the form of wisps of air that are free in the air, but the aura stored in the higher power stones is condensed into a flowing liquid and condensed into a liquid.

Holding it in your hand and looking closely, you can see that there is a flowing mass of material surging inside the high-level power stone full of cosmic energy. The desire exploded, but the power stone firmly bound this cosmic energy inside the crystal.

The platform in the center of the cave has an energy harvesting and circulation device that serves as a hub for the size of a fist. The azure blue power stone is a high-level power stone.

Low and medium power stones are generally used for civil power by prehistoric civilization humans, and high energy stones are relatively scarce, and are used in national energy and power applications, such as laying energy harvesting devices, supplying a city's power generation, using strategic weapons and so on.

For the charging of gemstones, the most common practice is to absorb solar energy under the sun.

There is also a large-scale energy harvesting device to collect all kinds of free energy in the universe, and then charge the power stone by transmission.

Prehistoric humans who cultivated civilization used power stones so extensively. It is widely used in various power sources.

In the information transmitted in the memory jade. There are also various uses of power stone energy by power stone people, such as how to arrange an energy harvesting device, the use of power stone energy in power and even the use of power stone energy in weapons, and so on.

It is told in great detail. It benefited Lin Chen a lot.

The power stone man's use of cosmic energy made Lin Chen breathtaking.

About submarine potholes.

At this time, a vein appeared in Lin Chen's mind.

Prehistoric humans discovered a gemstone mine here.

They began mining this gemstone mine.

After more than ten years or decades of mining, prehistoric humans dug a pit with a surface area the size of a playground and a depth of more than 300 meters, which was inverted cone and spiraled downward.

Finally, when the bottom of the pit is mined, in order to make it more convenient to mine, the power stone people have established a cave of several hundred square meters and more than 10 meters high, and the power stone people who are engaged in collecting energy stones have lived in the cave for a long time.

The power stone people built a platform in the center of the cave, and an energy collection and circulation device was laid on the platform to provide power energy for the collection and excavation tools of the power stone people, and the light and oxygen conversion of the cave also needed energy.

They collected energy stones in the pit for more than ten years, decades, until they thought that the power stone mine had dried up and could no longer collect power stones.

They abandoned the potholes.

After knowing the origin of the power stone, Lin Chen lacked the entire relic, after all, a large number of items such as blood bodhi and immortal phoenix blood on his body contained powerful energy.

However, these things are indeed quite helpful to the martial artists of the Martial Domain, Lin Chen believes that the three of Yun Zhen have enough deterrent power, after all, there are so many people present, none of them are in the late stage of entering the Dao, after reading it, Lin Chen left with peace of mind

A few days later, Yun Zhen and the three of them really returned with thousands of low-level middle and high-level energy stones, and the cultivation atmosphere of the entire Mingyue Palace suddenly improved, and even the members of the standing guard were all standing guard while holding the energy stone in their hands to cultivate, because the energy stone can be charged, so the entire Mingyue Palace is one per person, I believe that in a few months, the cultivation of the martial artists of the entire Mingyue Palace can be greatly improved

When the members were working hard to cultivate, Lin Chen was not idle, he was collecting some genius treasures in the inventory of the Mingyue Palace, maybe the blood Bodhi had eaten too much, and there was resistance in his body, now it was difficult for Lin Chen to improve his cultivation after eating the blood Bodhi, but Lin Chen was very urgent to improve his cultivation, because he always had a sense of depression in his heart

His heart is not only full of worries about the catastrophe, but also fear of the next world, referring to the wind and cloud world, the level of the next world will probably be higher, and the enemies that appear will be more terrifying, so if he can't break through quickly, I'm afraid it will be difficult for him to come out, he can feel that there is a pair of hands in the underworld, constantly pushing him forward, once his cultivation can't keep up, he can only be eliminated (to be continued. )
