After leaving the palace, Li Xin returned to his mansion for a while, and then, under the surveillance of many people, he walked around Yonglefang again. When he returned to the gate of the Jing'an Marquis Mansion, the sedan chair in the palace had been waiting for a long time. The eunuch Xiao Huai, dressed in purple, bowed and said, "Tao Fu, Your Majesty has been waiting for you for a long time."

Li Xin nodded, lowered his hands and got into the sedan chair, and said, "Let's go."

The sedan quickly entered Yong'an Gate, but it did not stop at the gate of Weiyang Palace, but stopped at the large schoolyard in the palace. The emperor dressed in green clothes had been waiting at the schoolyard for a while. When he saw Li Xin's carriage coming, he walked over in person, lifted the curtain of the sedan, and spoke to Li Xin inside: "The teacher has finally arrived."

Li Xin walked out of the sedan chair in a short shape and bowed to the emperor: "Your Majesty has been waiting for a long time."

The emperor narrowed his eyes, looked at Li Xin's cuffs, and said, "Have the teacher brought the things?"

Li Xin nodded, took out a clay pot about the size of an adult fist from his sleeve and held it in his hand.

In other words, the cuffs of clothes of this era are wide, and only if such a big jar is placed in the cuffs, it is impossible to see at all.

The emperor took the pottery jar in his hand, looked at it carefully, and then looked at Li Xin.

"The teacher is sure this thing will explode?"

Li Xin nodded: "Of course it will explode."

He reached out and said, "Your Majesty doesn't believe it, I can click it for you to show it to you."

"That's not necessary."

The emperor looked at the pottery jar, his eyes turned, and said to Xiao Huai beside him: "Go and get the dagger."

Xiao Huai immediately found a knife and handed it to the emperor with both hands. The emperor held the pottery jar with one hand and pried open the seal of the pottery jar with a dagger with the other hand. Then he saw the black powder in the pottery jar.

After doing this action, the emperor looked up at Li Xin, with a faint smug look in his eyes.

Li Xin frowned first, then looked at his eyes and nose.

The emperor asked the eunuch to take a small porcelain bottle, and used a dagger to remove half of the medicine powder from the clay pot, poured it into the clay pot, and then sealed the clay pot again. After doing these actions, the Nine Five Supreme hands were already black and looked quite sloppy.

However, he looked excited and looked back and looked at Li Xin with a smile.

"Teacher, if this pottery can be blown up, it doesn't matter whether I want the rest of the thunder."

This is to blatantly break the contract.

The emperor wanted to get the physical objects of the heavenly thunder in order to get the sample of gunpowder and hand it over to the Ministry of Works for research. He has now taken out half of the gunpowder powder in the clay pot. If the clay pot can be fried, that is to say, the powder is real. With the physical objects, it is not so important whether to have other heavenly thunders.

After getting the "sample", it was impossible for him to let Li Xin go out of Beijing again, and he would not even let Ye Mao go out of Beijing!

Marquis Jing'an's face was calm. He put his hands in his sleeves and said lightly: "I taught Your Majesty a long time ago that small means cannot accomplish great things. Once this thunder is formed, it cannot be taken apart, otherwise it will fail."

As he said that, Li Xin pointed to the pottery jar on the ground with only half of the powder left, and laughed: "Your Majesty may as well give it a try."

The smile on the emperor's face suddenly disappeared. He personally took the torch from the eunuch beside him, walked to the center of the schoolyard with the clay pot, lit the paper that caused the fire at the seal of the clay pot, retreated aside, and then stared at the clay pot in the center of the schoolyard.

The fire paper burned out quickly, and the flames penetrated into the pot. However, the pot only made a muffled sound, a stream of white smoke came out, and there was no movement again.

The emperor looked ugly, he looked up and glared at Li Xin, gritting his teeth.

"Teacher, you lied to me again!"

"I didn't lie to Your Majesty."

Marquis Jing'an said calmly: "Your Majesty wants to lie to me."

He walked to the emperor, reached out to take the torch from the emperor, walked to the center of the schoolyard by himself, and then magically took out another pottery pot from his sleeve, lit the fire-driven paper, and calmly retreated aside.

The flames burned out, and the results were very different.

The clay pot made a loud noise and exploded!

The center of the schoolyard immediately became white smoke, and fragments of the ceramic fragments scattered everywhere, splashing everywhere.

Li Xin put his hands together in his sleeves, slowly walked to the emperor, and bowed slightly: "Your Majesty saw that I did carry thunder on my body and did not deceive Your Majesty, but Your Majesty wanted to be clever, which ruined the rare trust between us."

The emperor's face suddenly became gloomy and sunny.

He couldn't figure it out now. The first clay pot didn't explode. Was it because he broke the seal or because the powder of clay pot was fake!

If it is fake, that is to say, all his behavior was predicted in advance by Li Xin and responded to it!

If it is true, then the emperor, he, is judging a gentleman's ambition by the heart of a villain.

What's even more terrible is that he dared not bet on whether these medicine powders were real, because he couldn't afford to bet. Dajin urgently needed to get the thunder, and it was impossible for him to miss three years for this!

Thinking of this, Emperor Yuan Zhao snatched the porcelain bottle filled with medicine powder from Xiao Huai on the side, and threw it to the ground. The porcelain bottle fell to the ground and became shattered in an instant.

He first glanced at the white smoke that had not yet dissipated in the center of the school ground, then turned around and smiled reluctantly at Li Xin: "I am just joking with the teacher. Tomorrow I will issue an edict to release Ye Mao out of Beijing and return to Jizhou to lead troops, and then draft an edict to let the teacher go north."

Marquis Jing'an smiled and said, "Your Majesty's joke almost cost me my life."

If the emperor got the sample of Tianlei in advance, then Li Xin would at least end up being imprisoned for life. If he didn't do it well, he would be killed by the emperor.

The young emperor smiled and said, "No matter what, I will not kill the teacher."

He waved to Xiao Huai on the side and said, "Xiao Huai, send the teacher back home on my behalf."

Li Xin didn't say anything more, bowed to the emperor, then got back into the sedan chair and left the campus.

The emperor looked at Li Xin's direction away, his eyes full of resentment.

He looked down at the pile of broken porcelain pieces and black powder on the ground, and said coldly to the eunuch beside him: "Colle them all and send them to the Ministry of Works to hand them over to the craftsmen. If there is still a little black and gray here tomorrow, you will find a way to die for yourself."

When he said he wanted to, the emperor groaned and left.

The dozen craftsmen around him were so scared that their faces turned blue. They knelt on the ground and began to collect the black medicine powder.

At this time, the sedan chair carrying Li Xin was about to arrive at the gate of Yong'an Gate. After walking out of Yong'an Gate, Li Xin stopped the inner guard carrying the sedan chair, then walked out of the sedan chair and said, "You go back, I'll walk back the rest of the way myself."

The inner guards looked at each other, clasped their fists at Li Xin, and then walked away with the sedan chair.

At this time, the sky was already dark, and the moonlight spread down, illuminating the bluestone road in Yonglefang and the light blue city wall of Yong'anmen Gate behind him.

Li Xin walked a few steps behind his hands, and then turned around and saw the Yongan Gate that he was very familiar with.

In more than ten years, he has entered and exited this palace gate countless times.

"You are much worse than your father."

Under the moonlight, Grand Tutor Li shook his head and sighed softly: "It's far worse than Emperor Zhao."
