Looking at all this, Jiu Ming was convinced for a while, Tian Chu's movements Jiu Ming saw it very clearly, Tian Chu's set of decision seals was very ordinary, but very practical.

This set of final seals is the manipulation of the true qi in the meridians, first compressing the true qi and index finger, when touching the backstab, the true qi is like a spring that has been released after being compressed for a long time, not only pushing the backstab to accelerate, but also like super glue sticking to the backstab.

The backstab drilled into the mixture at a very fast speed, and the extremely low temperature made the mixture quickly solidify, and Tianchu took advantage of this extremely short solidification process to quickly pull the true qi filament and pull the backstab out.

The closest to the backstab is naturally the fastest to solidify, so there is such a mixture, like the bean skin picked up on the surface of soybean milk, wrapped on the backstab.

"The principle is clear, but this is too demanding for the control of time!" Jiu Ming said secretly in his heart.

The apprentices present also understand this principle and the know-how in it, but it is too difficult to operate.

"Amazing! Second brother, your son-in-law deserves to be a bronze man!" he patted Leopard Xueyang's shoulder and praised him.

Xidele also stepped forward and put his arm around Leopard Xueyang's shoulder, "Second brother, why don't you help us ask your son-in-law, the secret of this control of time!"

Leopard Xueyang glared at Xidele is and shook off the salty pig hand.

Xidele is confused, the big man hooks his shoulders and backs, that is a proof of affection, how can this guy actually have a disgusted look that only a girl has.

"The third, the second, you can't move, people only have his son in their hearts!"

Xidele suddenly realized, and hurriedly opened a small distance with Leopard Xueyang, for fear of being bent.

After Tianchu's demonstration, the backstab of Kurosaki Fish from Fujia Commercial House was sold out, and some people even offered three times the price to buy it, but they couldn't buy it.

"Money shopkeeper, the rich armor firm has always been known for its complete materials, during this time, how come there is not even a grade A Kurosaki fish backstab, this is inevitably a little unconvincing to the reputation of your rich armor firm!" a young man said with some unhappiness.

This is the third time Bai Lian has come here to buy, but there is still no goods, which is really infuriating.

"Bai Gongzi, there is no way to do this, recently your Forge Alliance has purchased a large number of them, and the Kurosaki fish backthorn in this piece of my Fujia Commercial Bank has been wrapped!"

When Bai Lian heard this, he began to beat a drum in his heart, when did the Forge Alliance purchase such a large number of Kurosaki fish backstabs, and as an old man with a hammer of bronze, how could he not know about it.

"Money shopkeeper, do you know who purchased it?" asked Bai Lian calmly.

The money shopkeeper thought for a while, "It seems to be a tutor, and he said that it was for teaching!"

Bai Lian didn't continue to ask, turned around and left.

Along the way, Bai Lian secretly guessed in his heart that the mentor would purchase so many Kurosaki fish backspines, and the inventory within a radius of thousands of miles was gone.

Back at his residence, Bai Lian said to a young man behind him, "Zhu Hou, you will inquire later, which tutor's teaching used Kurosaki's backstab!"

Zhu Hou took the order and left, and began to knock on the side in his circle of contacts to inquire about the news.

At this time, there was jubilation in the classroom, and after Tianchu demonstrated it to everyone several times, many groups began to do it themselves, and these materials were naturally brought by Qian Duoduo, otherwise it would be impossible for the rich armor firm to sell all the backstabs.

"It's done!" Qian Duoduo held the newly formed Kurosaki arrow in his hand, with a smug expression.

Click!

A crisp sound came from Qian Duoduo's palm, and small pieces hit Qian Duoduo's face, and it hurt.

"My money, my materials!" Qian Duoduo was in pain, this was his tenth forging, and he still failed.

Tian Chu patted Qian Duoduo's shoulder, "It's okay!"

Qian Duoduo looked at Tianchu's sincere color, and suddenly picked up his confidence and prepared to come again.

"Anyway, you have money!" Tian Chu made up for it fiercely, but it didn't seem to hit Qian Duoduo, but made Qian Duoduo more and more proud.

"Yes, Master can't do anything else, it's Qian Duoduo!" Qian Duoduo grinned, and the forging table was once again covered with materials, a full five.

The other apprentices present were all envious, it was good to have money, as long as there was a little bit wrong, they would start again. And I have to scrutinize again and again, and analyze again and again before I dare to continue.

In just three days, many people have successfully forged Kurosaki arrows, and as for the power, on the surface, it is still very good.

And the first person to succeed was none other than Jiuming, who succeeded on the first day. As for the second person, that is, there is a lot of money, which is completely smashed out with money, and in a day and a half, more than 20 materials were consumed, which completely lifted half of the total consumption of materials.

That night, Qian Duoduo was arrogant, and took everyone to the cafeteria to eat chicken legs, and then went to the school field to test the power of Kurosaki's arrows.

Holding Tianchu's armor-piercing crossbow in one hand and Kurosaki's arrow in the other, Qian Duoduo is full of pride.

"Don't show off, hurry up, while it's still dark, we can go to the classroom to forge another round!" Tianchu shouted at Qian Duoduo.

Kurosaki loaded the arrow, and Qian Duoduo's round hand was raised, pointing at the energy man three hundred meters away. This energy man is the result of the formation system, and it is specially used to experiment with the power of weapons.

Sou!

A cheerful sound of air friction spread, and everyone looked forward to it, staring at the energy man with the ability to resist blows in a solid layer.

Bang!

A muffled sound came out, and the energy man exploded directly and disappeared into the school field.

"I'll rub it, this power, if you don't pay attention to the solid powerhouse, you will either die or be injured!" said in a low voice, with his eyes wide open.

The others also nodded, and they were also happy in their hearts, having such a Kurosaki arrow was a means of saving their lives.

"Huh, Kurosaki Arrow!" Zhu Hou narrowed his eyes slightly, looking at Tianchu and his party who were leaving from a distance.

11111111111111111111111111111111111

Bai Lian stared at Zhu Hou for a long time, "This year's apprentice forging Kurosaki arrow?" Bai Lian said in disbelief.

Zhu Hou's face suddenly turned a little pale, "Brother Lian, I saw with my own eyes, that fat man exploded the energy man on the solid layer with one arrow!"

Bai Lian frowned slightly, not that Bai Lian didn't believe Zhu Hou, but all this was too scary, and a group of apprentices began to forge first-grade weapons, if a certain person forging is acceptable, after all, there are so many top-notch ones in every session.

"You go and explore the truth again!" Bai Lian decided to let Zhu Hou go and explore.

Zhu Hou only took the order with a bitter face, to be honest, letting an old student go to the freshman's classroom, without a suitable reason, it was easy to be outraged.

In the classroom, everyone is full of enthusiasm, if it weren't for the lack of forging tables, otherwise the forging scene would definitely be quite spectacular.

This night, more than half of the apprentices successfully forged the Kurosaki Arrow, which really surprised Tianchu.
