My brother is so cunning.

The original impact cannon of Iron Man's armor can only cause impact damage and ionization burns, and its power is limited compared to bullets.

The Banana Yinfeng Impact Cannon developed by Wen Rui by copying the Banana Fan Magic Power is not so much a technological weapon as it is a magical power that conforms to scientific laws.

After precise calculations, the high-speed spiral airflow like a tornado is used to shrink the wind. Under the restraint of the airflow, the huge amount of Yinfeng is compressed into a line, and the scattered terrifying energy becomes extremely concentrated.

The huge energy is concentrated at one point, and the pressure and tearing generated are like a super alloy drill, which can easily drill through the tough hard skin of the demon king level.

Once a small hole is opened on the surface of the skin, a huge amount of spiral airflow rushes into the wound, which can produce a cavity effect in the body and cause great damage.

Wen Rui had woven the Banana Fan Magic Pattern on his body and tested it before. The clone tested exploded instantly and exploded into a ball of meat foam because of the gas implosion in the body.

It can fan out a hurricane that can blow people away for 108,000 miles. The power of the implosion of the airflow is no weaker than the shock wave of a hydrogen bomb explosion.

A demon king-level Rakshasa can withstand a hydrogen bomb explosion next to him. First of all, the force-bearing area is small, and it does not bear all the energy released by the hydrogen bomb. Secondly, being blown away by the shock wave can relieve more force.

But if a hydrogen bomb explodes in the body, all the energy will be borne by the fragile internal organs. Only a huge blood hole will be blown out on the back. It is considered that Dusan's demon body is extremely strong and as hard as diamond.

Wen Rui walked forward and came to the demon king. He raised his left hand again. The sound of the impact cannon charging sounded, and a blue beam of light flew out of his hand.

This time the target was the demon king's head. The beam of light hit the face, and the next moment Dusan's head suddenly exploded.

The hard skull could not withstand the huge intracranial pressure, just like an over-inflated balloon, it exploded with a bang, and the bone fragments flew and scattered like sand.

The headless demon king still stood there, his hands unconsciously groping at the place where his head used to be.

"Demons are really hard to kill!" Wen Rui frowned and couldn't help but sigh.

The vitality of the ancient demon god was so strong that even the water bear had to admit defeat.

For example, Xing Tian, ​​even if his head was cut off, he could still use his nipples as eyes and his navel as a mouth, and dance with a dry halberd.

Even if his head was cut off, he would not die, and he could still retain his fighting power.

Just like Chi You, after his death, his head and limbs must be buried in the boundless world, that is, the heaven, the underground, the human world, the North Pole, and the South Pole.

Otherwise, if he was left alone, he would be resurrected after a while.

Looking closely, Wen Rui actually found that the broken neck of the demon king had begun to grow granulation. It looked like if he was left alone, a new head would grow out soon.

Wen Rui then understood why many highly accomplished monks in the East could only seal some powerful demon kings but could not completely kill them.

Even if the Demon King is sealed, the seal will loosen after hundreds or thousands of years, and he can still break out and stir up trouble again.

Wen Rui looked at him with some envy. He also gained a strong self-healing ability with the help of nano units, but he was not like the Demon King in front of him, who could regenerate even if his head exploded.

His weakness now only has his head. Even if other limbs and organs are gone, he can immediately control nano robots to form artificial organs to replace them.

But once the brain is gone, the thinking has no material basis to rely on. Once the soul leaves the body, it must go to the reincarnation disk to reincarnate according to the rules of the prehistoric world.

That is death in the general sense.

Because Wen Rui's soul is bound to the system, and the system has set the rule that the soul must fall into the hell after death, he can't go to the reincarnation disk at all.

He quietly collected some samples of the Demon King's cells for subsequent research. Wen Rui controlled the shadow of the netherworld hidden in the battlefield in advance with his mind. Countless phantoms of absolute zero penetrated the ground and appeared, rushing towards the incomplete body of the Demon King.

Visibly, the demon king's flesh and blood began to coagulate, and the growing granulations on the wounds on his neck and back were also frozen, and his regeneration ability seemed to be paused.

The shadow of the netherworld of the Bose-Einstein condensate is immortal and always maintains absolute zero. As long as it continues to possess the demon king's body, it can be frozen forever.

In this way, it can be regarded as a disguised seal of this demon king.

Summon a transport ship, collect the remains of the frozen demon king's body and load it onto the ship. Wen Rui plans to transport it to the mortal world and directly jump into the core of the sun to incinerate it.

This kind of biochemical waste with meme pollution, no matter how difficult it is to kill, can be harmlessly treated by the sun.

Huang Tianhua came to Wen Rui's side, his attitude became much more respectful, and he smiled and said: "Brother, I was blinded by my arrogance before, but the master beside me was blind... Now I have suffered a great loss, and I have finally come to my senses."

At this point, he bowed and said: "Please teach me how to win against such a strong enemy with a tough body and tenacious vitality."

Facts speak louder than words. Huang Tianhua, who always thinks highly of himself, is now really convinced by Wen Rui.

Although he was greatly suppressed by the environment, he was defeated and almost died here. Huang Tianhua is also an upright warrior who disdains to make excuses or comfort himself.

He fought hard against the powerful enemy who was defeated, but Wen Rui easily used a few magical powers to crush him. Huang Tianhua finally understood today the true meaning of "knowledge is power" that Wen Rui had said to him before.

Of course, the Wen Rui who said this was actually the shadow warrior Jarvis, but it doesn't matter.

At this moment, he remembered Wen Rui (still a shadow warrior) who taught him such wise sayings as "There must be a teacher among three people" and "Be quick to learn and don't be ashamed to ask questions", and he was no longer shy and asked boldly.

"In fact, as long as you use the Heart-piercing Nail well, you may be able to defeat the demon king just now."

Wen Rui had a kind face and put on a master's manner, pretending to be a close brother in front of Huang Tianhua: "When you use the Heart-piercing Nail, you only seek speed instead of change, and go straight to the heart."

"This method is a quick kill against ordinary cultivators, but against Shuras and Rakshasa with tenacious vitality, even if the nail pierces the heart, it is just a tickle."

Huang Tianhua nodded repeatedly: "That's right, in the past, when fighting with others, the Heart-piercing Nail has repeatedly made achievements, but now it doesn't work. I really don't know what to do."

"Seek innovation, seek change, start from reality, and make reasonable improvements." Wen Rui gave a vague advice.

Huang Tianhua fell into deep thought, and after a moment, he shook his head with a bitter face and said, "When Master Daode Zhenjun gave me the Heart-piercing Nail, the formula he taught me was to control the nail to shoot straight. If I change it rashly, wouldn't it be a betrayal to my master? Besides, I am far inferior to Master, so how dare I change the secret method he passed down?"

"You, you have only been an immortal official in the Heavenly Court for a few years, how come you have become so pedantic? Have you heard of the saying 'Master leads you into the door, and practice is up to you'? Only with the spirit of questioning and challenging authority can you surpass your teacher!"

Wen Rui angrily scolded, "Haven't I been teaching you the way of thinking of Jiejiao for more than a year?"

"Make bold assumptions, carefully verify, observe carefully, and summarize the rules. The sixteen-character mantra of the Jietian Secret Method is to teach you to innovate and develop, and open up your own martial arts!"
