After Lin Yu heard Shi Zhongyue's words, his heart couldn't help but feel a little heavy.

It seems that Shi Zhongyue, the dean of the academy who seems harmless to humans and animals, still has strong ambitions in his bones.

However, Lin Yu did not decide that Shi Zhongyue was a bad old man or anything like that.

Everyone has their own ideas, and the definition of good people and bad people is never divided by ambition.

A gleam also appeared in Zhao Chuanying's eyes, Shi Zhongyue's words were like lightning that pierced the night, and for a while he seemed to have found a new idea.

Lin Yu's expression was calm, although the movement that Zhao Chuanying made just now had a certain lethality.

But you can't let the enemy enter the stone hall and wait for Zhao Chuanying to explode unexpectedly, right?

Of course, the old man just said it casually, after all...... There must be a lot of problems involved, and the old man is not a genius, so it is difficult to understand the mystery......"

Shi Zhongyue smiled, looked at Lin Yu and said, "Try your new discovery?"

"Good!"

Lin Yu already had a countermeasure in his heart, so he asked for materials from Zhao Chuanying, and skillfully began to match......

In order to confuse Zhao Chuanying, Lin Yu also added a lot of processes that could have been removed, and half an hour later, a new firework was successfully born......

"That's it...... Okay?"

Zhao Chuanying looked at Lin Yu with a confused expression, and said that he would build two in more than ten years?

But it's only one in half an hour.

Lin Yu nodded and said, "Well, okay! After leaving the academy in the past few days, I suddenly had a flash of inspiration, and I completely understood it......

Shi Zhongyue and Zhao Chuanying couldn't hide the surprise in their eyes, and they were even more amazed by Lin Yu's understanding.

Zhao Chuanying has not succeeded so many times, and as soon as Lin Yu came, he created new fireworks.

He even doubted...... Is Lin Yu hiding it?

Although Zhao Chuanying received a critical attack from Lin Yu...... But after hearing the Tao, the master is the teacher.

So he humbly asked for advice.

Lin Yu said helplessly: "The disciple doesn't dare, in the eyes of the disciple, fireworks and firecrackers are just a childhood plaything, and if you put them on festivals, you can't do the right thing......"

“......”

“......”

Shi Zhongyu and Zhao Chuanying were silent at that time, and what they said seemed to make sense.

They were just curious, so they focused on fireworks and didn't take into account ...... After this thing is made, it doesn't seem to have any other benefits except for a little increase in income for the academy.

After the freshness is over, it seems to be like that, but it is colorful, and the children like it very much......

For a moment, the atmosphere in the stone hall immediately became a little awkward.

In fact, fireworks are such a thing in the first place, can they still be used to kill enemies?

But the Heaven-Shaking Thunder can't be taken out, after all, this thing is one of the powerful weapons of Great Xia......

Therefore, when Lin Yu was tinkering with fireworks, he extinguished a little ambition of Zhao Chuanying and Shi Zhongyue by the way.

In fact, Lin Yu once again fooled Shi Zhongyue and Zhao Chuanying......

"You have to have a beginning and an end to everything, no matter what...... The college only needs to master the art of making fireworks......"

Shi Zhongyue was very open-minded, and after determining that fireworks and firecrackers only had the meaning of ornamentation, they could not bring substantial benefits to the academy, so he simply got the formula......

Leave your wealth to posterity......

Zhao Chuanying nodded.

In this regard, Lin Yu stood solemnly on the side, but in fact, his heart was happy.

Under Lin Yu's detailed explanation of the production method of fireworks to Zhao Chuanying, Zhao Chuanying also successfully made fireworks......

The joy of success made Zhao Chuanying feel relieved.

In any case, he still succeeded! The name of a master is not in vain.

It's just that after knowing that the production of fireworks and firecrackers is so simple, Zhao Chuanying immediately became interested and tasteless......

I can't help but deny the hard work of the past month.

"Ahem......"

Shi Zhongyue coughed lightly twice, then glared at Lin Yu and said, "You have long known that the production of fireworks and firecrackers is very simple, but only two ...... are made Deceived the old man, didn't you?"

Of course, Lin Yu would not admit it, shook his head and said: "It was very difficult before, but I just heard about the success of Master Zhao's research and the harvest of these days, and I found out that ...... It was that simple. ”

Shi Zhongyue looked at Lin Yu deeply......

But at this moment, a voice came from outside the stone hall: "Master Zhao, about this batch of talents shipped to the Tang Empire...... Datang sent a letter asking when it would be able to be delivered......"

Zhao Chuanying, Shi Zhongyue and Lin Yu left the stone hall room, the former took the letterhead from the hands of the disciples of the Tiangong Hall who passed the message, looked at it, and said: "Reply to Datang, set off in half a month, escort......ed by the three disciples of the inner courtyard of the Holy Heaven Academy."

"Yes!"

The disciple was ordered to leave, and Lin Yu had a gleam in his eyes after hearing the news.

Dai Qian's information is really correct, and ...... Half a month is enough for him to prepare well.

Lin Yu has always been a person who protects his shortcomings, and if anyone moves his scales, it is a hatred that does not share the sky.

So...... Ji Wushuang and the others must die!

"Master Zhao, are those talents of high grade?" Lin Yu suddenly asked.

Zhao Chuanying didn't know why Lin Yu suddenly asked about this, but he still told Lin Yu and said softly: "They are all ordinary talents, the ...... used by the royal family of the Tang Empire to supply the prince's guards"

"Oh!"

Lin Yu nodded, and at the same time, he breathed a sigh of relief in his heart, as long as the talent was not expensive.

lest the three disciples who were escorting the talent weapon accidentally die violently, causing the Heavenly Crafts Hall to suffer huge losses, this is not the result that Lin Yu wants to see.

......

Later, Lin Yu also learned a little about Tianxin Tower under the leadership of Zhao Chuanying, including refining talent weapons and inscriptions and inscriptions.

This is the best heaven and earth spiritual object for forging talents and inscribed divine patterns and inscriptions, which is rare.

Without Tianxin Yan, the Heavenly Gonggong Hall will not be able to create high-grade talents.

This was originally a secret, but Zhao Chuanying felt that since Lin Yu was an all-round disciple, if nothing else, he would inevitably have a place in the Holy Heaven Academy in the future.

Let's get a good relationship first, and when the Tiangong Hall asks for resources from the academy in the future, there will be a convenient door to go.

However, when Lin Yu and Shi Zhongyue left the Tianxin Tower, all of a sudden, Lin Yu felt hot all over his body, and at the same time felt like he was being watched......

Then the scene in front of him changed abruptly, and in a trance, he seemed to see a burning man covered in blue flames, slowly walking towards him......

At the same time, all the Heavenly Craftsmen of the Tianxin Tower also suddenly noticed the changes in the Tianxin Flame.

The temperature of the Tianxin Tower rose sharply, and countless talents that were about to take shape directly exploded into ashes......

Shi Zhongyue saw Lin Yu standing still, his eyes were not focused, but the disciple Dao Seal in the center of his eyebrows was constantly flashing with golden light.

At the moment when Shi Zhongyue didn't pay attention, a small blue flame appeared in Lin Yu's eyes, and then slowly disappeared......
