Although the thing Tianlei has been out in the second year of Taikang and has existed for eight or nine years, this thing has been well hidden by Li Xin, and until now, the world, or the imperial court, still doesn't know what it looks like.

This matter was regarded as a taboo in the last years of the Taikang Dynasty, and no one dared to mention it in front of the emperor, so naturally no one would mention it in front of Li Xin.

From the end of the eighth year of Taikang, Tianlei was officially exposed to the vision of the imperial court, and for almost two years now, no one in the capital has mentioned this Tianlei directly to Li Xin.

The little emperor was the first to bring up the matter.

And with this half-joking tone, if you bring it up in front of Li Xin, there will be no problem, Li Xin is his elder after all, and he can't turn his face with the child no matter what.

In this way, I can test what kind of mind I have as a teacher.

After hearing Li Xin's reply, Yuan Zhao Tianzi was full of interest, and he immediately spoke: "I just heard about this thing earlier, and I have never seen it, can the teacher give me two and play with me?" ”

No matter how secret Tianlei is, after all, it is a thing in the world, as long as there is a physical reference, plus so many skilled craftsmen in the Ministry of Industry, it can naturally be studied slowly.

The Marquis of Jing'an bowed his head deeply and said: "There are three in the minister's mansion, and two can be sent into the palace tomorrow to be dedicated to Your Majesty, and as for the remaining one, it can be used to demonstrate to Your Majesty." ”

Yuan Zhao Tianzi was overjoyed, pulled Li Xin's sleeve and said, "It just so happens that I have nothing to do today, why don't you show me today?" ”

At this time, it was already close to evening in the afternoon, Li Xin looked up at the sky, and then nodded with a smile: "Then Your Majesty will wait here for a while, and the minister will go back to the house to get the heavenly thunder." ”

"Okay."

The Son of Heaven spoke: "I am in the school field of the palace, waiting for the teacher to come." ”

Li Xin bowed his head respectfully, turned around and withdrew from Weiyang Palace, left the palace from Yong'an Gate, and returned to the Jing'an Hou Mansion.

In the backyard of the Marquis of Jing'an's Mansion, there were indeed thunderstorms, and there were not only two or three, but as many as forty or fifty.

These are the things that Li Xin brought out from Jincheng, one is to defend himself on the road, and the other is to ...... It is used to prevent the court dog from jumping off the wall.

If the imperial court wants to be unfavorable to Li Xin, or if Li Xin is forcibly detained, these things can be taken by surprise, and with the cooperation of people in the shadows, there may be a chance to escape from the capital.

More than fifty clay pots were neatly placed in Li Xin's study, and in addition to him in the study at this time, there was also Shen Gang who had followed him for many years.

Marquis Jing'an frowned and thought for a while, then walked out of the study, and it didn't take long to move back to a wine jar that was much larger than a person's head and put it in the study.

He opened the wine jar, and then stretched out his hand to greet Shen Gang.

"Here, take a hand."

Shen Gang scratched his head and squatted next to Li Xin.

"What does Master Hou want his subordinates to do?"

"Take these heavenly thunders apart, and pour the medicine inside into this wine jar."

Although Shen Gang didn't know why, his biggest advantage was that he was obedient, and when he heard the words, he immediately started to do it, and with the joint efforts of the two of them, soon at least twenty or thirty of the gunpowder in the fifty heavenly thunders were poured into this wine jar.

The heavenly thunder is only a little bigger than an adult's fist, and because the inside is to be sealed with fish glue and the tightness is controlled, there is not much gunpowder, and more than twenty heavenly thunders barely fill this wine jar.

Li Xin found another piece of tulle paper, rolled it into a lead, sealed the opening with fish glue, got up and looked at the wine jar, and clapped his hands with satisfaction.

"This thing should scare that kid."

At present, the gunpowder is not powerful enough, and simple heavenly thunder can only hurt people but cannot kill people, but dozens of heavenly thunder gunpowder stuffed in a jar is terrifying enough.

After all, the equivalent is here.

Thinking of this, Li Xin stretched out his hand to greet Shen Gang again, and the two of them ran to the kitchen, moved back to the two slightly smaller wine jars, and divided the remaining Tianlei medicine powder into two parts and poured them into these two wine jars.

Not enough to obviously pretend to be dissatisfied, Li Xin said to Shen Gang: "Go find some plant ash, flour, dried loess, and arrowroot powder." ”

Shen Gang did not hesitate and immediately went down to prepare.

The first wine jar is naturally used to explode, to create a shocking scene, the remaining two are dedicated to the emperor, naturally it is impossible to really give it to him, there is no shortage of talented people in this world, just a few doctors in the Tai Hospital, they can ask for medicinal ingredients by smelling it, and it is inevitable that there will be no craftsmen to figure out the formula.

But as long as these things are mixed in, it will be difficult for the Daluo Immortals to perfectly restore the gunpowder from this pile of clutter.

After preparing for an hour in the Hou Mansion, Li Xinxin's carriage took the three wine jars and entered the palace from Yong'an Gate, all the way to the school field in the palace.

At this time, in the center of the school field, the Son of Heaven had already asked people to set up two wooden figures and two scarecrows.

Li Xin and Shen Gang moved the big wine jar from the carriage and moved it to the center of the school field, placing it in the middle of the four dummies.

Then Li Xin asked Shen Gang to wait here with a torch, he turned around and walked to the Son of Heaven a hundred steps away, bowed his head and said: "Your Majesty, the heavenly thunder given to the minister from the southwest has been placed, and as soon as Your Majesty gives an order, the minister will let the general set it on fire." ”

Although the Son of Heaven is already the king of a country, he is still a young man after all, and when he sees this kind of novelty, he will inevitably be curious, he rubbed his hands a little excitedly, and said, "Teacher, can I personally go and light this thing?" ”

"Nope."

Li Xin shook his head very decisively: "Your Majesty, this thing has been seen in the southwest, it is quite dangerous, Your Majesty is the Ninth Five-Year Supreme, how can you be in danger?" ”

Yuan Zhao Tianzi waved his hand happily.

"Then the teacher asked someone to order it."

Li Xin nodded, stretched out his hand and made a gesture to Shen Gang in the distance.

Shen Gang understood, and lit the fuse of this wine jar with the torch in his hand, and then the strong man ran away quickly, and ran twenty or thirty steps away in just a while.

Boom!

The wine jar behind him exploded!

Today's heavenly thunder is Lin Hu's continuous experiment in Yongzhou, and the ratio of power is relatively large, plus the equivalent in this wine jar is very huge, once ignited, the instantaneous light illuminates the entire school field, and also illuminates the stunned Son of Heaven.

After the loud noise, the Son of Heaven looked at the center of the school field in a daze.

The two straw figures were gone, and the two wooden figures were devastated.

Yuan Zhao Tianzi's voice was a little stumbling.

He turned his head to look at Li Xin and said in a trembling voice, "Teacher...... Is this the thunderbolt? ”

Marquis of Jing'an nodded indifferently.

"It's a thunderstorm, but the people in the southwest are treacherous, and the thunder for the minister is not necessarily the best, and I'm afraid there are even more powerful thunderstorms in the southwest."
