Because several of Sun Xiang's disciples all stayed in Binhai, after the revival of the aura, Binhai City was the first to have a perfect cultivation theory and exercises.

But it's not just practitioners who are busy.

Professor Xu Yongzhi led the research team to conduct an in-depth analysis of several basic supernatural techniques provided by Lightning. Scientists have come to two conclusions through experiments:

First, Reiki is somewhere between existence and nothingness, and only in a special way can it truly exist. And this special way is the technique.

Second, the form is a fixed structure of the spiritual field, but only the divine thoughts of intelligent beings can stimulate the field effect.

Under the guidance of these two theories, the scientists of Binhai successively conquered the transmission and storage technology of spiritual energy, and finally developed the current pulsed spiritual energy diffusion cannon.

The six giant antennas in Marina City, each of which is densely packed with independent structures, are all a type of air induction. When excited, these antennas can widely absorb the free aura between heaven and earth.

This is equivalent to the dantian of a cultivator.

And the "barrel" of the diffusion cannon is the crystal ball on the metal rod. This pure crystal ball uses extreme ultraviolet laser technology to depict a wind blade palm form - a more powerful form that cannot be engraved at the moment.

This is equivalent to the Purple Mansion of a cultivator.

The last person to connect the aura and the magic type to manipulate was Xu Yongzhi who was in the cockpit.

Because only the spiritual platform of the practitioner is the divine thought, scientists cannot simulate and replicate it. The cockpit can only be installed in the aura diffusion cannon, which can be connected to the cultivator's divine thoughts in the form of neural connections.

Yes, the great scientist Xu Yongzhi is also a cultivator, magical. He is just not of high rank, and he can be worthy of the qi induction period. But it was more than enough to manipulate this aura diffusion cannon.

Intense incandescent light condensed in the crystal ball, making the city look like a small sun.

The emperor's heart was shocked, and he even took a few steps back. In his divine sense, the power condensed in the crystal ball far exceeded him. This is simply a huge spiritual power that only a demon king can have, and this power is now aimed at him!

He couldn't care about the lightning for the time being, and his heart was retreating, but it was too late at this time. The spiritual power condensed on the crystal ball had reached its limit, and the frequency of the ripples shaking faster and faster, and finally suddenly disappeared out of thin air.

In the next instant, hundreds of thousands of wind blades flew out from the aura diffusion cannon, converging into a fan-shaped torrent, aiming directly at the black giant under the city wall.

The Wind Blade Palm is a very basic attack Dao method, and it is only used by apprentice-level cultivators to cut down trees. For a strong person at the level of a demon general, the Wind Blade Palm is like a small water gun, and there is no threat.

But what if hundreds of thousands of water guns are fired at the same time, do you understand how to wear dripping stones?

The Emperor experienced this amazing sourness.

Each wind blade hit the armor, but it consumed a little bit of his demonic energy. However, tens of thousands of wind blades were slashed down at a speed that could be called furious, and the momentum on the emperor's body was palpable. His hand holding the sword trembled uncontrollably, and many new cracks appeared in the broken armor out of thin air.

If this continues, the Great Emperor will be consumed alive by the lowest level wind blade. In the midst of the difficulties, he did not fear in his heart, but felt very ridiculous. If he dies like this, I don't know how the witch king laughs at himself.

The Witch King didn't laugh at him, but tried to rescue him by all means. The competition between demon generals is fierce, and if you are not careful, you will be devoured by your kind. But it doesn't mean that there are no good friends among the demon generals.

A giant worm burst out of the ground, blocking the torrent between the Great Emperor and the Wind Blade. This big insect is called Earth Dragon, and it is actually a giant earthworm demonized. It even grows thick and sharp bristles all over its body.

This is the general under the Witch King, and it is also his mount, so his defense is naturally quite good. Therefore, a little bit of time was bought for the Witch King.

He turned into a black rag, wrapped around the Walking Corpse Emperor, who was no longer able to move, and then flew away with a thud. In mid-air, the Witch King glanced back.

His Earth Dragon mount had broken into several pieces under the blow of the aura diffusion cannon, and its stump twisted and struggled on the ground, spewing out pus. The Witch King flew to safety and put the Emperor down. Before he had time to feel heartache for his mount, he suddenly noticed a heart-piercing pain in his back.

It turned out that when he fled with the Emperor, the aftermath of a diffusion cannon swept through his heart. The Witch King is not known for his defensive power, and this is a not light injury.

From the launch of the aura diffusion cannon to the witch king's escape from the emperor, everything happened between lightning and fire.

At this time, the aura shining from the muzzle of the cannon has been extinguished, and the crystal ball has returned to its original state. This attack cost five million megajoules, but unfortunately it failed to kill a demon general on the spot.

Despite this, injuring the two-headed demon general is already a remarkable achievement!

All the human defenders cheered. You must know that in the entire coast, only the Martial God Lord Yu Xiaoyue can help a big demon of this level. In the past, humans could only help destroy some small monsters.

And the significance of this blow is by no means just to injure the two demon generals.

This is the first time that human beings have tried to combine science and metaphysics, and they didn't expect the effect to be so amazing, they actually seriously injured the general-level demon with almost mortal strength. Only Lao Lu knew the meaning of the people present, he had a long mouth, and he was incredibly persecutive.

"It's really a horse!"

Xu Yongzhi, who was in the cockpit, took off the nerve link helmet in annoyance. He was actually not satisfied with the effect of the attack.

Because the Witch King saved the Great Emperor, he realized the huge weakness of the aura diffusion cannon:

Attacks cannot be tracked or locked.

If you encounter a demon general who is particularly fast, you will definitely be able to avoid it.

And the power is not very strong, and it didn't evaporate the demon general in an instant.

However, the more powerful and accurate attacks are too complicated. It is very difficult to process the excitation crystal ball at the front end of the diffusion cannon, and adding the wind blade type to it is already the limit of the existing human process.

Others don't know, only he knows that this kind of excitation crystal ball is not infinitely used. In fact, with the full load fired just now, the crystal ball would have to be replaced with a maximum of ten shots.

All in all, Xu Yongzhi, with the harsh attitude unique to scientists, devalued this aura diffusion cannon to worthless.

But the demon generals are about to cry here!

The two-headed demon general retreated some distance, still not at ease, and finally hid behind a hill.

The Emperor was not lightly injured, and he said angrily: "Didn't the charm spirit say that the power was out over there for forty hours!

The Witch King is not as upright as the Great Emperor, and his heart is uneasy. The demon clan can crush humans, in addition to its strength, the most important reason is that the level of spiritual power is higher than that of human technological weapons.

There are many powerful weapons on the hands of human beings, and the power of attacking the body of the great demon is less than one. But now the strange weapon at the head of the coastal city has broken this common sense.

The damage of the aura diffusion cannon to the demon clan is real!

Human beings can already use technology to control spiritual power? If this is the case, the accumulation of science and technology in the past few thousand years of human beings is definitely not comparable to that of the demon race. In this competition for survival between the entire demon race and humans, the advantage is gone.

What to do?

Is it to retreat or to attack?

Under the cover of the Misty Demon Forest, tens of thousands of demons under the three demon generals are already within the siege range, which is a once-in-a-lifetime opportunity.

But if the energy supply has been restored to the Marina, the siege will be a heavy loss.

And, don't forget the strange psychic weapon. If it were launched again, the two demon generals would not dare to say that they would be able to escape with their whole body.

In the midst of hesitation, the sound of moving mountains came from under his feet.

"If we go home empty-handed like this, His Holiness will not be able to give an account. We all know what happens if His Holiness is not satisfied. ”

At the mention of His Holiness, both the Great Emperor and the Witch King were silent.

"This is the last chance, try again, everyone give it their all. Yishan continued, "This time I was at the front, I saw the attack just now, and I should be able to resist for a while. You must take the opportunity to destroy that weapon!"
