My brother is so cunning.

Wen Rui had already mastered the technology of nano-unit weapons many years ago.

After all, this function is the basic configuration of Iron Man's nano armor.

Before, when fighting with others in the mortal world, Wen Rui rarely used this function. At most, he constructed a black technology tractor beam ray launcher.

As for the construction of melee weapons, he never used it once.

The main reason is that the strength of weapons composed of mortal iron is too weak. Even in the Marvel Universe where they come from, nano melee weapons are far inferior to vibranium weapons or mandela alloy weapons.

Coming to the prehistoric world, the physical strength of the cultivators in the Nascent Soul Realm is not much worse than that of the purple potato spirit, and nano weapons can't break the defense at all.

This led to Wen Rui having to rely on the golden hoop implanted in his body and fight with his hands empty when fighting with others in close combat.

After sweeping the warehouse and blueprint library of the Tiangong Supervisor, the fairy-level nano robot was successfully developed, and the situation was finally completely changed.

The nanometer units made of the composite material of the divine iron of the heavens, after forming weapons, have a structural strength far exceeding that of ordinary iron, and can be blessed with merit and spiritual light, turning into a divine weapon in a short time.

The comprehensive properties have reached the level of the heavenly generals and immortal soldiers produced by the immortal craftsmen of the Tiangong Workshop.

The hardware has the conditions for mind control to build nanometer immortal soldiers.

At the same time, the blueprint library of the Tiangong Supervisor and the technology transfer of the immortal craftsmen under the coercion and inducement of their superiors also enabled Wen Rui to obtain a full set of heavenly army weapon manufacturing technology.

The cloud patterns of the heavenly way, the carvings of the formations, and the secret codes of the spells engraved inside the immortal weapons can all be arranged by nanometer units in an instant.

With the combination of hardware and software, the nanometer immortal weapons can restore the heavenly generals and immortal weapons with a degree of simulation of nearly 95%.

It may be slightly inferior to the real immortal weapons, but the advantage is that even if it is damaged into powder, it can be reshaped and repaired with a thought.

Moreover, as long as the corresponding full set of data is stored in the database, the nanometer units can be controlled to build instantly, change as desired, and take shape immediately.

All basic tests had already been completed on the portable secret Jin'ao Island. Wen Rui came to the Tianwu Arena of the Xianwu Hall to find an opponent with decent strength to test in actual combat.

After all, no matter how good the data of the weapons in the test field is, you will never know whether there are defects if you don't go to the battlefield for actual testing.

Although Nezha was not injured when Hun Tian Ling blocked an arrow, he also felt that his immortal power was stagnant. The heavenly general-level divine arrow with a restoration degree of 95% was not so easy to receive.

One or two arrows may be easily blocked, but if you defend for a long time, you will lose. Seeing Wen Rui draw the bow and arrow again, another arrow was shot. Nezha did not retreat but advanced, and rushed forward fiercely against the golden arrow.

The red tassel of the fire spear turned over, rolling up a fiery tornado. The golden arrow was detonated by the flames in the air before it hit the target.

Breaking through the blasting air wave, the spear tip stabbed again. Wen Rui put his hand back and grasped it, and a golden spear phantom took shape between his hands.

The fairy-level nano-unit is driven by thoughts, and the speed of building components is incredibly fast. The long spear condensed into a solid body in an instant, and the spear body collided with the fire spear, blocking the opponent's weapon.

Swinging the fire spear away, Wen Rui turned around and stabbed back with a backhand. The golden spear in his hand burst into lightning, and a series of electric light crackled. The thick lightning snake wrapped around the fire spear body and transmitted it to Nezha.

Nezha, who was surrounded by thunder, groaned. He was not prepared and did not have time to apply the lightning spell in advance. His body was shocked by the electric shock, and his body was inevitably stiff due to the pain.

Being shaken away by Wen Rui's shot, the boy widened his eyes and stared at the lightning golden spear. He said in disbelief: "This is obviously the fairy weapon power of the flying electric spear. How can you turn into Brother Huang's flying electric spear?"

Wen Rui just smiled and didn't say anything. He raised his hand again, and a flying nail condensed in his palm. As soon as the flying nail was formed, it rotated at high speed, and the huge spiral force rolled up a whirlwind.

"Impossible, that's Brother Huang's Heart-piercing Nail!"

Nezha was shocked and quickly held the Fire Spear across his body. He had served in the Zhou army with Huang Tianhua, so how could he not know how powerful the Heart-piercing Nail was? He immediately became extremely careful.

Wen Rui pointed in the air, and the flying Heart-piercing Nail shot out. Nezha had no time to react, and felt a cold wind blowing over his body, and there was a sharp pain in his chest.

The Flying Electric Spear and the Heart-piercing Nail were not what Wen Rui asked from the immortal craftsmen in the Tiangong Workshop.

As early as in the Demon Realm of the Earth Realm, Wen Rui got the original version under the pretext of helping Huang Tianhua upgrade his equipment, and conducted very detailed reverse engineering research.

Although the manufacturing technology and materials used had been analyzed at that time, it was difficult to copy it because the corresponding rare raw materials could not be found in the mortal world.

Now Wen Rui has no shortage of materials from the heavenly world, but he does not need to copy it. He can enter the data and control the immortal nano units to build it.

It's just that the nano-immortal weapon version is not the original version after all. If it were replaced with the original Nezha's lotus body, it would probably be pierced through the heart.

The nano-copycat version of the heart-piercing nail has a high degree of speed and tracking ability, but the structural strength is insufficient. It only penetrated half an inch when it hit Nezha's heart, and it shattered into slag when it hit the lotus ribs.

Even if it only penetrated an inch into the flesh, the high-speed rotation force tore a large piece of flesh and blood. Nezha's chest was bloody and translucent lotus juice kept pouring out.

Outside the Tianwu Arena, countless heavenly soldiers and generals had already gathered around. Everything that happened in the arena world could be seen on the viewing platform.

The fierce fight between Wen Rui and Nezha was seen clearly by the gods and generals, causing a series of exclamations.

"My goodness, the little Tai Shi Wen Rui was obviously a civil servant back then, and I have never seen him rush into battle. It turns out that his martial arts are so amazing that he beat General Nezha without any resistance."

"That's not right. Junior Brother Wen was not good at martial arts back then. He couldn't even beat the rats in the sect."

Many belligerent Doubu Star Lords often come to the Tianwu Arena to vent their energy. The one who said this was Wen Rui's Jinlingxian Sect senior brother Kui Mulang.

"You guys underestimated Junior Brother Wen back then. He was not good at martial arts because his aptitude was too poor to practice and improve his realm, not because he couldn't learn the moves and techniques."

Another Doubu Star Lord, Wen Rui's uncle and Jiejiao senior, Qi Shaxing Zhang Kui said: "That kid once asked me for the art of walking on the ground. At that time, I couldn't refuse Master Wen's face. Seeing that he was only in the Qi training stage, even if he heard the secret, he couldn't practice it, so I taught him everything I knew. I never thought that although his realm was low, his wisdom was extraordinary. He easily mastered it overnight and used it freely at the Qi training stage."

As Zhang Kui said, Wen Rui was not good at martial arts before, not because he couldn't learn the exquisite moves, but because it would be useless even if he learned them.

If the realm is too low and the physical fitness is too poor, no matter how exquisite the moves are, they will be defeated by force. It is better to hide your shortcomings and pretend to be a martial arts idiot to reduce the enemy's vigilance.

Now Wen Rui has achieved the merit and holy body through the Conferred God. Although his physical fitness is far inferior to the top generals who have achieved the holy body through physical cultivation, his hardware configuration has reached the passing line for the display of martial arts skills.

No matter what kind of weapon he conjures, with the immortal weapon in hand, Wen Rui can perform exquisite moves at will, and he will not lose to Nezha in a fight, just like a weapon master who has been immersed in martial arts for many years.
