Although they were already convinced that Yu Hua's engraving would eventually fail, Liu Chengxi and Niu Mao still stared at him.

This knife technique is so exquisite, so exquisite that even they are amazed!

Is this Yu Hua's strength? that terrifying perception and control ability!

Seeing Yu Hua's specialness, at this moment, they all left the sharp sword in front of them behind.

Compared with forging a sharp sword and giving it to that big man, Yu Hua's talent in refining weapons is more meaningful.

The two of them turned their heads in unison, saw each other's similar eyes, and nodded at the same time.

Such a genius, we must let him stay in our Academy!

Liu Chengxi whispered: "Looking at his technique, there may be hope!"

He knew in his heart that there was a mistake in the formation pattern in Yu Hua's memory, and in this way, it was impossible to create a weapon with sharp special effects, but this was not completely without a chance.

As long as it's better than the defective products that were created before, although it still can't be a gift for that big man, it's better to get some blood back.

The other disciples and teachers, looking at Yu Hua's movements, did not know that the formation engraved by Yu Hua was no longer sharp.

Just looking at Yu Hua's extremely skillful movements, the thoughts in their hearts were also shaken.

A pattern appeared on the body of the sword, and the steps of Yu Hua's engraving had already entered the end, even those disciples who couldn't understand the engraving knew that now was the critical moment.

The hand holding the engraving knife was still steady, and Yu Hua did not hurry to engrave according to the pattern given by the data flow in his mind.

Engraving patterns is not something that any refiner or martial artist can do, although it does not require much qi and blood power, but it is extremely depleting for the spirit.

If you are not careful, you will carve the wrong strokes because of lack of concentration, and in this way, everything will be wasted.

With the help of the data flow in his head, every stroke he makes is as precise as a printer, and even the attention allocated to it is meticulously detailed.

The last stroke, as before, did not make any mistakes, and it was also at this time that his spiritual power was exhausted, and he could no longer pick up the engraving knife in his hand as smoothly as before.

But his performance has surpassed all the teachers and disciples present, even Liu Chengxi and Niu Mao, they can't compare!

A burst of light flickered, and this was the effect of the formation engraved by Yu Hua.

"What is this?"

Liu Chengxi and Niu Mao turned their heads abruptly, looking at each other with uncertain eyes.

Generally speaking, if the formation is engraved on the weapon, if it is successful in the end, it will show some unusual special effects, such as the light in front of you that exudes the residual power of the formation.

It is very difficult to forge weapons engraved with formations, but the two of them have successfully built a few weapons in the Arsenal for so many years, and with the assistance of foreign powerhouses.

Then there was a strange flash of light, which was somewhat similar to what was seen in front of him.

But looking at the ordinary sword body, it seems that the blade is no longer sharp under the erosion of time, and the appearance of this weapon is even worse than an ordinary sword.

For a while, they couldn't determine whether this was a successful build, or was it another type of formation engraved by Yu Hua?

"Alas, it's a pity, in the end, it failed, the remaining materials are no longer enough to build another long sword, and there is not enough time!"

Looking at the long sword in front of him, which was obviously a failure, a disciple sighed and said quietly.

The top management of the Arsenal had made a decision a few days ago to forge a weapon with sharp characteristics.

To this end, the Instrument Academy dispatched all the skilled craftsmen and made repeated attempts, hoping to forge a weapon with sharp characteristics belonging to the Tenglong Instrument Academy.

They were also very happy to be selected as the disciples, but after several attempts, they still failed in the end, which can't help but make people feel regretful.

"If the final engraving were made by someone else, would it be successful?"

A disciple took out a drawing with a sharp formation pattern, and after comparing it, he found that the pattern engraved by Yu Hua was different from the one recorded on the drawing.

"There is a good hope of success this time, but unfortunately it is still a failure, if Senior Brother Yu Hua can come a few days earlier and memorize this formation pattern, there will be no such mistakes and omissions. ”

Those disciples knew how difficult this final engraving process was, and when they saw Yu Hua's performance, they were also convinced.

Although there were some regrets at this time, no one blamed him, because everyone knew that Yu Hua had done better than many people present.

It's just a pity that he couldn't memorize the drawings, if he remembered, maybe this construction would really be successful!

After putting down the engraving knife, Yu Hua sat cross-legged and rested for a while, although he followed the steps of the data flow in his mind, but his consumption was still very large.

Liu Chengxi and the two also stepped forward.

They looked at the long sword on the platform in disbelief, but no one moved.

"Niu Lao, Liu Lao, our materials are no longer enough, why don't we forget it this time?

Let's go back and make plans, maybe those big people don't look down on such weapons, everyone think about it again, maybe you can find some gifts that match that person's preferences!"

After a few days of hard work, I still couldn't create the kind of weapon I wanted, a teacher suggested.

"Wait"

At this time, Liu Chengxi raised his right hand to stop the teacher's words, he looked at the long sword on the platform, but his eyes were a little solemn.

Niu Mao also said loudly: "You also feel it?"

They were far away before, and although they were surprised by the light when the engraving was completed, looking at the not sharp blade, they also thought that this time the creation was a failure.

But as they approached, they noticed that the sword was a little different from the one they had made before.

The body of the sword exuded a strange aura from top to bottom, as if it was a devouring tiger, exuding a terrifying aura, which made the two of them feel a little palpitation.

This is by no means an ordinary weapon, and there is a characteristic of blessing on it!

Liu Chengxi picked up the long sword, he looked at it carefully, looking at this weapon that was not even as sharp as an ordinary long sword, he was very curious.

But after some scrutiny, he didn't find anything peculiar about it.

"Old Niu, come and see, this sword is a little weird!"

Hearing his words, the surrounding teachers and disciples also cast strange glances.

Could it be that there is something different about this sword, isn't this a defective product that has been created?

They concentrated on the movements of the two people in front of them.

The formation pattern on the sword was engraved by him, and Yu Hua naturally knew the characteristics blessed on this long sword.

Bleeding, an additional trait that is no worse than Sharpness.

He had already rested, and he knew the effect, but he only watched from behind, and did not come forward to remind him.

Ahead, Liu Chengxi and Niu Mao were still looking at the long swords on their opponents.

This ancient sword looked like it had been rusted away, and no one might want it for free, and they really couldn't imagine why it gave them palpitations.

Niu Mao thought of Yu Hua, the great hero of the engraved formation, who was sitting cross-legged and resting on the side, and just wanted to go back and ask his opinion.

At that moment, the blade accidentally slashed across his palm.

A crack opened, and blood flowed like an outpouring of blood!
