Chapter 692 The Secret that Doesn't Need to Be Returned

boom!

Another muffled thunder sounded.

Ye Yu held the forging hammer high and landed on the ore again.

With Ye Yu and the forging platform as the center, bursts of air continued to spread around.

Many disciples of the Dao League couldn't resist the surging air waves, and had already retreated far back.

The disciples who were pushed away by the air wave looked at each other and couldn't help but smile bitterly.

"Tsk! It turns out that the strength is low, and you don't even have the qualifications to watch Ye Yu's forging?"

"It's terrifying! It's just the aftermath of the forging that I can't contend with!"

"This Ye Yu is so powerful! Every hammer is a forging technique! It's inhuman!"

"Just get used to it, he is no longer on the same level as us!"

boom! boom! boom!

Forging continues.

The air waves swept through the air, and a tornado was formed around Ye Yu, and it rose into the sky, which was spectacular!

Tian Leizi narrowed his eyes slightly, staring at Ye Yu's movements without blinking.

In Tian Leizi's view, every movement of Ye Yu was flawless and full of natural rhythm.

After watching for a while, Tianleizi suddenly reacted.

It was only then that he realized that the ore on the forging table seemed to have never returned to the furnace after it was burned red from the beginning!

"how can that be?!"

You must know that during forging, once the temperature of the ore decreases, its hardness and adhesion coefficient will increase exponentially!

At that time, whether it is to deform the ore or remove impurities, it will become very difficult!

Therefore, when forging, the ore is always returned to the furnace several times!

And Tianleizi forged the sword tire before and returned the ore seven times.

For this, Ye Yu also reprimanded Tian Leizi.

In Tianleizi's heart, there is still some dissatisfaction.

Could it be that he, Ye Yu, can only heat the ore once is enough?

Now that Tian Leizi has seen it, Ye Yu really heated the ore once at the beginning!

And in the next forging, Ye Yu hammered hammer after hammer, and did not stop at all!

Not to mention returning the ore to the furnace in the middle!

"How did he do that?!"

Tian Leizi watched Ye Yu's movements in shock, not missing a single bit!

Suddenly, Tianleizi's eyes widened, because he found something that surprised him!

On top of the iron felt, that piece of bronze ore that became more and more red, not only did the temperature not drop.

The heat on it seems to be even hotter!

Looking at the ore that exudes astonishing heat, like a small sun, Tian Leizi doubts life!

"Are you surprised?"

Ye Yu's voice, accompanied by waves of air, floated into Tian Leizi's ears.

Tianleizi nodded numbly.

"Then look carefully!"

As Ye Yu fell, the forging hammer in his hand landed on the ore again.

boom!

Ye Yu's whole body was condensed with strength, and with this hammer, he smashed onto the ore.

"Control your strength! Distribute it evenly on the ore!"

"Every time you beat, a part of the kinetic energy will be converted into heat energy, so that the temperature of the ore will not drop, and it will even get hotter with the hammer!"

Ye Yu's words were like a flash of lightning, and instantly flashed in Tian Leizi's mind.

"It can still be like this!"

This time, Tian Leizi completely worshipped Ye Yu.

boom!

With the last hammer falling on the ore, Ye Yu stopped.

The fiery ore scorched the void, twisting the surrounding air, making it unreal.

Tianleizi saw Ye Yu stopped.

After a few steps, I came to the forging table.

Opening his eyes wide, Tian Leizi looked at the ore lying quietly on the iron felt.

The previous bronze ore was the size of a grinding disc, and the surface was undulating and rough.

Now the ore is just a cube the size of a palm!

The turquoise is like a piece of emerald ore, lying flat on the iron felt, like a treasure, reborn in the sea of ​​fire!
