However, he felt that he could now consider further compressing energy, and at the same time, he was also considering another issue.

Manpower is exhausted and beyond our capabilities.

Compared with the endless energy contained between heaven and earth, the energy contained in such a small body is limited after all. Just like in the blood lake, although the infinite true energy that Wang An realized and practiced

It's awesome, but compared to the almost endless blood lake, there is a big gap in "quantity" after all.

So, is there any way to make the energy in the human body infinite?

There are two methods. One is to maximize the use of the energy between heaven and earth. What is between heaven and earth is one's own. If this step can be achieved, the energy between heaven and earth is readily available. To a certain extent, it can be achieved.

Endless, but this method has a big drawback. Once you are in a very limited space, or the space is "blocked" by someone, there will not be so much energy to borrow.

Another method is to improve yourself as much as possible, enhance the "energy" quality in the body, continuously compress and increase density.

The gaseous state becomes liquid, the liquid state can become solid, the solid state can continue to be compressed, the star becomes a white dwarf, and the white dwarf becomes a neutron star.

Wang An personally prefers the latter method.

"Then the next thing to consider is "dan formation"."

He has successfully changed his own Qi form once, and now he is considering changing it a second time.

"How to form an elixir?"

This is a professional term for a Taoist practice. The so-called "when a golden elixir is swallowed, my destiny is determined by me and not by heaven." It refers to cultivating the golden elixir.

However, the method and effect of this kind of practice are definitely different from what Wang An thought and practiced.

He has read more than one such Taoist classic, but the descriptions of how to practice the golden elixir are very mysterious and there is no clear route. Maybe the people who compiled these ancient Taoist books were not able to successfully practice the golden elixir in the end.

.

Wang An is not in a hurry, he has plenty of time. One year is not enough, two years is not enough, two years is not enough, ten years is not enough.

He can already feel that his life span will be much longer than that of ordinary people, if nothing unexpected happens.

Thousands of miles away, on the outskirts of the crack known as the one leading to the underworld, a temporary military base has been built, and the sound of gunfire has been heard for several days.

Monsters are constantly rushing out from there, not only the humanoid monsters, but also those with long tails and weird wings. These monsters are fast, powerful, and have high defense, causing damage to the warriors defending here.

suffered huge damage.

"Damn, what are these monsters, are they endless?"

"This is not the way to go."

"We have to find a way to go down and see what's in there!"

After several meetings to discuss and study, they suddenly carried out a strong counterattack. The fierce firepower suppressed the monsters that kept rushing out of the cracks, and at the same time, they sent several specialized surveillance and observation equipment into the cracks.

They want to find out what is in the crack.

As a result, they saw black smoke billowing and monsters climbing up the rock wall.

Relevant equipment was destroyed again and again, and they delivered it again. After trying again and again, they finally saw a bronze door with a crack in the deep underground, the billowing black smoke and those weird things.

The monsters all rush out after pressing the bronze door.

"In other words, as long as we find a way to close the bronze door, we can cut off these monsters and block this highly corrosive black smoke!"

"Theoretically, it's like this, but the problem we face is how to dive to a depth of 254 meters underground amidst the siege of these monsters, and then close the bronze door that seems to weigh at least dozens of tons."

"The distance of more than 200 meters is not a problem. We just need to dig out a passage on the rock wall. Open the passage first and then go down below."

It is not an easy task to dig a passage in a hard rock wall, but the base specially invited a special team to have practitioners dig the passage and provide cover for them with automatic firepower.

Not to mention, the speed at which they dug passages exceeded many people's imagination. The originally hard rock was easily broken under their digging. The key was that these people dug passages and hunted monsters without fail.

"I didn't expect these people to be so powerful. Let's just put them down and see if they can close the bronze door."

"No, now they can accept fire protection. Once they go underground, our firepower cannot provide them with all-round protection due to the obstruction of the rocks on both sides. The number of monsters they have to face will increase sharply, and it will be difficult to guarantee their safety.

Safety."

They dug passages in front, set up paving equipment, and then poured concrete continuously.

Just like this, in more than ten days, they actually built a downward passage. Although it was a bit rough, it could already accommodate two people going down side by side.

With the completion of the passage, special monitoring equipment began to be installed. The first team of people went underground. After more than half of the damage was done, they came to the bronze door.
