As many years ago, Ling Zichen had already studied metals to the extreme. As the founder of the core of the positive circulation source of monomers, no one knows more about this than she.

She found that any metal has its limits, which leads to the core of the positive circulation of monomers.

The strengthening of metal can be carried out through forging. For example, when manufacturing the battle armor, the metal can be upgraded to the spiritual forging, soul forging, or even the god level. However, these metals that have been upgraded, especially metals after melt forging, will become impossible to refine them into the core of the monomer positive circulation source. Therefore, when manufacturing the monomer positive circulation source core, it depends more on the quality of the metal itself. If this problem can be solved, it is an important topic of the Douluo Federation's energy research.

To this end, Ling Zichen has been studying for hundreds of years and conducted countless attempts and experiments. With the powerful power and strength of the Tangmen and Shrek Academy, she has no restrictions on her research, and she has not been able to draw a better conclusion. She has only made great progress in how to concentrate on mobilizing more monomer positive circulation source cores, and how to use the core energy of monomer positive circulation source cores more efficiently, and has the initial accumulation of modern human cosmic technology.

Like the current Douluo Federation warships, there are countless single positive circulation source cores inside. These single positive circulation source cores form various arrays, and they are even compressed, guided, used, etc. through soul-guided magic arrays, so that the warships have stronger combat power.

But in fact, this is not what Ling Zichen wants. What she wants is how to greatly improve the quality of the monomer positive circulation source core, which will save more rare metals, and at the same time allow the monomer positive circulation source core to contain more enormous energy.

After countless years of research, she discovered a possibility, that is, the self-evolution of the core of the positive circulation source of monomers.

How can the monomer positive circulation source core evolve itself after being forged into an energy body? By chance, Ling Zichen discovered that biological energy has a stimulating effect on the monomer positive circulation source core. So she began to try to use different organisms to conduct experiments.

At the end, she was surprised to find that this was similar to the weapon that the soul master raised, and it could not be a soul guide, but an ordinary metal weapon, or a weapon that was forged with certain power.

If you can have strong enough strength and qi and blood, and allow the monomer's positive circulation source core to exist stably in the body, it will have the possibility of slowly evolving. As for how much it can evolve, it will take time to verify it.

This is also the basis for Ling Zichen to transform himself into a transformed person. This is why the ecological warships were later created.

There is no doubt that her research was successful. Moreover, until now she didn't know what the limit of the monomer positive circulation source core is in organisms. Because she and Yi Zichen have been raising this for thousands of years, the monomer positive circulation source core in their bodies is still growing. Although it is very slow, the sustainable growth is all underway.

However, this is difficult to replicate, because if you want to control the monomer positive circulation source core, you need to have strong strength. Ling Zichen conducted an experiment and can only control the monomer positive circulation source core more stably. Moreover, this thing is equivalent to implanting an unstable bomb in the body. If it is not good, the bomb explodes, then it will be completely destroyed. How many strong people are willing to implant this thing in their bodies? Instead of doing so, it is better to establish a monomer positive circulation source core array.

But Ling Zichen continued and continued to conduct inspections to determine the various characteristics of the core of the positive circulation source of this evolutionary monomer. She was successful. When these monomer positive circulation source cores were nurtured to a certain extent, she found that the vitality of energy became extremely strong and began to absorb external energy to replenish itself, which is the possibility of becoming a longer-term source of energy.

However, if you want to give birth to such a monomer positive circulation core, it must be fostered in the human body for at least a thousand years. This is really too expensive, which means that there is no way to promote it on a large scale. Therefore, this technology is still only within the Shrek Academy. The only cores that can truly nurture this monomer positive circulation core are Ling Zichen and Yi Zichen.

In all ecological warships of Shrek Academy today, there is actually a core of this monomer positive circulation source, so the Golden Eye Black Dragon King warship can be built in such a short time. The core of these monomer positive circulation source is Ling Zichen and Yi Zichen who have been nurtured in their bodies for thousands of years.

At this moment, what Ling Zichen had to do was to complete the final union with Yi Zichen and burst out all the energy remaining in their bodies, the core of the oldest monomer positive circulation source, under one attack.

She didn't know how powerful it was. But she understood that this might be their only chance.

She has lived for thousands of years and can still see Tang Wulin again. Although that guy is still with Gu Yuena, she has no regrets. She has survived half-human and half-mechanical for so many years. If she hadn't been thinking about Shrek Academy, she would have chosen to end herself long ago.

The cannon on earth ten thousand years ago! Today, ten thousand years later, it will be reappeared on earth!

There are circles of patterns on the metal muzzle, which seem to be made up of countless patterns. Among these patterns are her, him, and the pictures of them when they were together. This cannon was completely solidified on the muzzle of the Golden Eye Black Dragon King warship.

A strange red light kept flashing at the dragon mouth of the Golden Eye Black Dragon King Battleship.

The Crimson God King in the distance subconsciously looked in this direction. She was surprised to find that she actually felt the threat. The four major fleets of human Douluo Federation teamed up before and did not let her feel the threat. At this moment, she felt it.

What is that?

"Boom--" A huge red shell burst out at this moment.

When this red shell appeared, the entire universe seemed to be dimming for a moment. Ling Zichen once named this cannon, and it was called Wushuang.

It means that there is no one like Ling Zichen and Yi Zichen in the world.

After the Wushuang shells rushed out in an instant, the energy fluctuations of the entire Golden Eye Black Dragon King battleship instantly became weak.

"And——" The passionate dragon roar suddenly rang, as if he felt the human cannon being opened again, and Tang Wulin's emotions became obviously even more crazy. The bursting blood force forced free from the shackles and rushed towards the Crimson God King again.

The crimson God King's eyes were cold, and his right hand clamped into a fist, punching in the direction of the Wushuang shell. At the same time, circles of vortex ripples enveloped Tang Wulin again.

"Boom!"

The universe was shaking, and the blood light seemed to cover the entire universe in an instant. It was a combination of many monomer positive circulation sources! It was in the bodies of Ling Zichen and Yizichen for more than 8,000 years. The energy contained in this was the ultimate trump card of the entire Shrek Academy.
Chapter completed!
