It's just that at this time, the three elders didn't feel any sincere reverence in their hearts because of the terrifying aura emanating from the king's body. On the contrary, the more terrifying the aura released invisibly, the deeper the worry in their hearts became.

for the king was wounded. Only an injured peerless powerhouse would be unable to control his aura like this, revealing his terrifying might.

The breath of the former king is like an eternal and endless starry sky, in which thousands of stars are born and die, and the cycle is endless. And now, the king has become a raging sea, and how can the waves be qualified to support the entire undead race?

The counterattack of the Cult of Light became more and more intense, and at this time, on the frontline battlefield, five undead had already fallen. Although the Cult of Light also paid the price of eleven cardinal archbishops dying in battle, it was still the undead who could not bear the loss.

In the face of the Cult of Light's counterattacks, the king finally made a move and fought the mysterious and terrifying sect master above the temple in the void outside the sky. However, the goddess of the elven race, who also had the strength of a demigod, reversed her neutral attitude this time and stood strangely in the half of the Sect of Light.

Wang was one against two, but in the end he still lost half a move.

The outcome of this top-level decisive battle directly affected the battlefield on the ground. After the three demigod-level terrifying beings fought, the undead took the initiative to shrink their battle line and retreated their army to the north of the Eternal Night Forest, completely abandoning all the human territories they had occupied.

Just after the rout on the battlefield of the Eternal Continent, bad news also came out of a small earth battlefield. The undead who stayed there were slain by humans, and nothing could cause the wrath of the undead race.

A group of ant-like humans actually killed a noble undead. After the retreat of the Eternal Continent, the undead once again cast their eyes on the distant Earth plane.

The 20th day of the Dark Age.

After nearly a month of cultivation, Zhuang Yichen finally stabilized his realm and firmly raised his strength to the level of a great magician.

And the undead side, in just over a month, has also hoarded troops, preparing to launch a retaliatory Armageddon again.

During this period of time, in addition to stabilizing the realm, Zhuang Yichen pushed away all the celebration banquets and commendation meetings held by the military for him. Except for the prime minister who met him privately again, Zhuang Yichen tried his best to keep a low profile in other aspects.

Of course, even so, his name spread through thousands of households with radio reports. The times need heroes, and human beings in danger at this time need heroes even more. This is the need to boost morale and political propaganda, although Zhuang Yichen doesn't like it very much, but there is nothing he can do.

After cooperating with the military to make a few report meetings, Zhuang Yichen just practiced with peace of mind, and then met with Qi Han and chatted casually for a while.

Time flies, and a month passes again. During this time, the undead remained strangely silent, but everyone knew that this silence represented the calm before the storm.

From the army of necromancy that was constantly gathering outside Kyoto, from the terrifying aura that appeared outside Kyoto from time to time, the tension of the great war had been hanging over Kyoto all the time.

Kyoto was in constant danger of preparing for war, producing weapons and ammunition, stockpiling food, and building defenses. And all of these point to a paradoxical end, energy.

The industrial civilization on which mankind depends is built on energy, and after the end of the world, it can persist to this day under the terrifying attack of the undead, in the final analysis, it is all energy.

In Kyoto, there are hundreds of magma pools created by the undead in the early days when they transformed the earth's environment. These magma pools are self-defeating and provide all the mineral resources of the entire Kyoto base.

The lava behemoths had time to spread their branches on the earth before they were cleared by artillery fire. All that remains are these magma pools, which continue to produce copper, iron, and sulfur.

Although important strategic resources such as rare earths, tungsten and uranium are still scarce, there are at least enough copper, iron and sulfur to produce weapons and ammunition. All of Kyoto's energy supply depends on these nuclear power plants. However, nuclear fission power generation still has huge shortcomings and hidden dangers. Without enough energy, you can't breed enough food, dilute enough water, make weapons, or even activate large land-based laser weapons that threaten the undead.

If the energy problem can be solved once and for all, then humanity will no longer need to fight a war of attrition with the lives of the undead in the face of an endless army of undead.

Thousands of large laser weapons were directly set up, and everything was wiped out in one round of strafing. Why is the war so hard?

In the final analysis, it is still the level of human civilization that is insufficient. If human beings can complete the third scientific and technological revolution as soon as possible and enter the interstellar age, the strength of the undead will definitely be the result of being crushed by human civilization.

At this moment, truly solving the energy problem once and for all has become the key to the fate of the entire human race.

All the energy on the earth comes from the sun, so the solution to the energy problem of human beings is naturally very simple, to create a sun.

Mankind has stepped into the threshold of the atomic age, mastered the powerful nuclear weapons, and can even control the reaction of nuclear fission and build nuclear power plants.

But the problem of controlling fusion reactions has never been truly solved. In nature, the sun itself is a giant nuclear fusion reactor, where two elementary particles merge into one and release a huge amount of energy by losing mass.

Through this principle, humans have created a hydrogen bomb, which can release the huge energy generated by this fusion reaction in an instant, and become a weapon of destruction. However, it is not possible to control this chain reaction, so that the energy produced by fusion can be controlled by human beings, and endless energy can be generated for human beings in a stable and continuous manner.

The process of nuclear fusion is based on the isotopes of hydrogen, deuterium and tritium, which are produced by lithium in the ocean and in the ocean. As long as human beings can completely master controlled nuclear fusion, it means that the shackles of energy on human civilization can be completely broken.

In a sense, a complete solution to the energy problem means that the door to the second level of civilization will be opened, and space, time, and the mysterious laws of the universe will become within reach. Such a human civilization already has the strength to fight in the face of the magical civilization of the Eternal Continent!
