In the studio, there was nothing else except the buzzing of the atomic furnace.

The three sisters of the He family, the five brothers of the Zhao family, and Lu Ziwei stood honestly in the corner, not daring to show off, staring at the broken knife shining with cold light in Gao Yuan's hand.

The knife is broken, the edge is broken, and the blade is dull, but when this knife is in Gao Yuan's hand, it gives everyone a very strange sense of shock.

It was like an invisible god of death parasitizing on the blade, looking at it with his emotionless eyes and playing the game of "Pointing the Bingbing" with his pale fingers.

"Press the soldiers, point the thieves, who is the big soldiers, who is the big thief..."

Whoever is lit by the god of death will be buried under the knife!

This feeling was so strong that no one dared to speak out or even breathe heavily.

Gao Yuan held the broken knife in his hand, and a gentle aura was emitting all over his body, connecting him with the broken knife into one. A solemn expression appeared on his face, and his eyes were staring at the black iron embryo in the furnace.

"The time has arrived!" Two rays of light suddenly flashed in Gao Yuan's eyes, the corners of his mouth slightly raised, revealing a confident smile.

With a light touch of his finger, the alloy arm sucked out the black iron embryo. Gao Yuan controlled the broken knife to land on the carbonization anvil with one hand, and used the drip device of the alloy arm to drip the melted black iron that had almost become liquid on the broken knife.

A crisp sound of "swish" sounded, the sound tore through the air, and the blade made a slight trembling. When the black iron dripped on the blade, the knife seemed to roar, which made everyone's heart pound and almost jumped out of his throat!

The black iron fell down and did not solidify, but turned into a drop of iron and rolled on the blade. The scorching temperature of the iron burned the blade, making the broken patterns become clearer.

Gao Yuan glanced at the eye lines and his expression became more serious. He gently pushed the joystick and made slight adjustments to the alloy arm. This adjustment was calculated at a few millimeters of zero points. Any slight shaking of the muscles may affect the result, but Gao Yuan could do it to the extreme. He could make the angle and distance of whatever angle and distance he wanted.

As Gao Yuan's fingers gently moved, the iron slowly slashed across the blade. Suddenly, a crisp sound of "swishing" suddenly surged into a slight and almost invisible crack on the blade.

This drop of molten iron just made up the crack. Although it left a clear repair mark on the blade, no one could pick on it.

Next, Gao Yuan continues this step. Drop the iron, control the angle, and blend into the cracks.

First there were those tiny cracks, and then smaller cracks, one crack after another, and dark scars gradually emerged on the blade.

If the scar is a man's medal, then these cracks can also be regarded as the medal of this knife. It doesn't know how many fierce battles it has experienced and how many terrible enemies it has killed, so many scars left on the knife. And the knife is so severe that it has not been broken yet, it is really strong enough!

Every time a scar is repaired, the weight of the knife increases a lot. The density of black iron is too high and the mass is too high. The integration of every drop of black iron brings not only surface repair, but also weight, hardness and toughness. This is like changing a set of alloy skeletons for a seriously injured patient from the inside to the outside. Although it is scarred on the outside, it is actually a rebirth.

There were too many cracks, and Gao Yuan's micro-operation was extremely laborious. Gradually, large beads of sweat were seeping out of his forehead. Compared to the test of physical strength and endurance, mental fatigue was the greater enemy.

Fortunately, Gao Yuan was prepared, so he took out a pill and jumped into his mouth with his fingers.

The medicinal power enters the throat. Although the recovery speed is far less than that of consumption, it can relieve a lot of fatigue. Taking advantage of this short excitement, Gao Yuan gritted his teeth and continued to take action, repairing more than a dozen cracks in one breath.

Five hours!

When it was already dawn outside, Gao Yuan finally completed the repair of the last crack.

His body shook slightly and almost fell. This huge project used more than twenty kilograms of black iron. After integrating these black iron, the weight of the broken knife increased by more than ten times, which was no less than Yang Guo's heavy black iron sword weighing 64 kilograms.

The broken knife lay quietly on the carbonized anvil, covered with scars all over the body, each scar was black, as if an abstract transformation was formed on the blade.

Gao Yuan looked at the broken knife with satisfaction and smiled. Although the knife was broken, it almost rejuvenated after the repair of the black iron.

Although Gao Yuan had never seen the "Xuanfeng Sword" and "Dingkun Shield" unearthed with this broken knife, Gao Yuan believed that even if he met those two old friends, the broken knife would probably not be at a disadvantage.

"Hu..." Gao Yuan let out a long sigh, turned around and saw the friends who had been watching quietly in the corner of the wall, and smiled and said, "What do you think?"

"Is this the result of your repair?" He Meimei said with the most direct personality and a little incredible: "Is this too ugly?"

He Meiya pinched He Meimei for a moment and said awkwardly: "Meimei is talking nonsense, but is this really considered a repair?"

He Meiling also said curiously: "Why do I feel that this is like the culinary method mentioned in ancient books?"

Curcuma is an ancient technology. In an era when materials were not very abundant, when a utensil was broken, it would be repaired by curcuma. However, the curcuma method was to use metal nails to combine cracked places such as porcelain, pottery, and utensils, which was different from Gao Yuan's method of finishing the knife.

Gao Yuan said lightly: "Don't think it's ugly. It's just that it has gone through too many years and has some vicissitudes. As for whether it has been repaired, you will know after I match it with a set of sword techniques."

When Riemanshu heard that Gao Yuan had repaired the ragged knife, he came to Sanshu Institute to watch the fun.

When Riemanshu saw the appearance of the broken knife, he was shocked.

"I said Gao Yuan, this is too ugly!" Women are indeed all emotional animals. The first thing they pay attention to is the appearance: "And, this knife is broken and it is not repaired at all."

"It was originally a broken knife." Gao Yuan said.

"It was broken!" Riemanshu felt incredible: "Forget it, what you said is broken is broken, where is that big stone?"

Gao Yuan said: "I have smelted into black iron, and more than 20 kilograms are integrated into this knife."

Riemanshu looked at Gao Yuan and murmured: "You are really willing to pay for it, but why do I think this knife is not reliable? It seems that it will fall apart when you touch it casually. By the way, what is its name?"
