This drying time takes about two to three weeks. After all, it is not high-temperature drying, but ventilation and drying at room temperature, and moisture is also required.

Of course, Zhao Huan did not intend to be idle during this period. On the first day, he created a weight scale to use.

Chen Gui said that it was a bit troublesome to use, and after the weight balance was made, Zhao Huan smiled like a child Chicheng.

Sometimes men's happiness is really simple.

The appearance of a weight balance is definitely not a trivial matter in Zhao Huan's opinion.

Zhang Tanghua had no feelings about this, just staying with Zhao Huan's side is enough.

She knew what the government liked.

Zhao Huan returned to the palace late at night and went to the Military Equipment Supervision the next day.

He likes handicrafts very much, and he made a spinning ball by himself in the military weapon supervisor.

While the ball was spinning rapidly on the shelf, Zhang Tanghua watched it with concentration for a long time, but still couldn't figure out what it was for.

But looking at Zhao Huan's satisfied smile, knowing that this object is very important to Zhao Huan.

Zhang Tanghua solemnly put away the transfer ball. This is a gift made by Zhao Huan himself. Is there anything more precious than this?

Zhao Huan went to the military weapon surveillance for a few days after that, but he never took Zhang Tanghua again.

Because Zhu Lian looked at Zhang Tanghua's toys, his eyes were full of envy.

A few days later, when Zhao Huan returned to the palace, the gift he brought to Zhu Lian was a very ordinary transparent water cup.

And this water cup is the glass that Zhao Huan burns from sand these days, transparent and clear, like crystal.

Of course, this was also done by Zhao Huan.

The emergence of glass was a gift made by an official for Zhu Lian, but Zhao Huan knew that the significance of glass was very important, and the origin of optical instruments was also the beginning of chemical experiments.

It also marks the alchemist's rough and unrestrained experimental style, and has officially stepped on track and precise measurement.

A series of objects such as beakers, measuring cups, flasks, conical bottles, funnels, wide-mouth bottles, fine-mouth bottles, etc., appear within two to three weeks.

Since Zhao Huan became emperor, he finally played as he pleased for two or three weeks.

He is not playing, he is laying the foundation for chemical engineering in Song Dynasty. Instruments and precision are the incubators of chemical engineering.

During the three weeks of military weapon supervision, Zhao Huan finally got enough of his own addiction to handicrafts, and it was finally time for gunpowder acceptance.

Zhao Huan and Chen Gui stayed outside the pharmacy anxiously waiting for the gunpowder to come out, and even ate for lunch at the military inspector.

"Can the official family do it?" Chen Gui took the gunpowder out of the drying room with some thorns and iron sheets, and loaded the musket again, but Chen Gui still had some doubts.

"Try to be as long as possible, we are all away."

Zhao Huan felt that it was OK to be five or six feet away, but after thinking about it, he moved back five or six feet.

"Let's start. Just run away after you click." Zhao Huan told the relatives who went to ignite the lead and said.

The personal servant nodded and said yes. When he lit the fuse and ran back to Zhao Huan, there were about half of the gunpowder fuses, and they ran very quickly.

Several officials followed the officials and stood in front of the officials and many ministers.

"Bang!"

A sound like thunder came, followed by a jingling sound as dense as rain. It was the sound of iron inserted on gunpowder and the sound of a progressive human armor inserted.

There are several shelves around the gunpowder table with stairs armor placed on them, used to refer to the experimental results.

The sound of dense metal collision is the sound of countless iron pieces and the Bingren Armor colliding in the thorn cannon.

After this thunder and continuous heavy rain, everyone was stunned and staring at each other, not knowing what to do.

The sound was too loud, which caught them off guard.

Zhao Huan took out two balls of cotton from his ears in a leisurely manner. He had known that there would be a loud noise, so he had already blocked his ears.

At a distance of more than 30 meters, there were still iron pieces embedded on the wooden squid held by the personal servant. Zhao Huan looked at the depth and said secretly.

There was still a large amount of gunpowder on the test site, and even the sound of thunder was heard in Bianjing City.

Zhao Huan waited for the smoke to dissipate and saw that Bu Renjia's shiny surface was full of potholes.

Some iron pieces even passed through the weak spots of the Buren Armor.

Break the defense.

Zhao Huan smiled happily and said, "It looks very powerful."

Unfortunately, no one responded to him, and the loud noise still caused the ministers to fall into a brief state of deafness.

The formula provided by Zhao Huan is not even a method of making compressed gunpowder, and its power is about one-quarter of the tnt of the same weight.

But it still stunned Li Gang, Chen Gui, Su Xie and others.

The medicine cake is ground by Chengui, and the gunpowder is made by Chengui. Chengui looked at his hands in disbelief. What did he do?

Zhao Ying waited for a long time before entering the test site. He wanted to count the damage caused by Buren A to adjust the power of the gunpowder pack.

"The official family, the twenty-three stairs armor, all the armors were pierced, and most of the slings were pierced. The four innermost stairs armor even pierced the chest armor. It was very powerful." Zhao Ying returned to the official family.

The reason why he waited until the smoke of gunpowder dissipated and waited for a long time before he left was because he was afraid that some pills would not detonate.

This is something that the official has repeatedly told me, how dare Zhao Ying forget it?

"The official family is really a god who descends to earth!" Zhao Ying sighed sincerely.

When Li Gang and others thought of the rumors of Zhao Huan and Yan Luo's reincarnation, they kept nodding. It must be that the immortal god came to earth, otherwise, just a piece of paper could create such a human killing weapon?

"Let the musketeers try it." Zhao Huan thought for a while and said, "This is the first test, please be careful. Just leave everyone."

If the gunpowder of the terrestrial cannon is extremely successful, the black gunpowder of the firing medicine is also very cool, almost all of which are exploded.

When it is several times more powerful, continuing to use bamboo poles is really a humiliating gunpowder.

Only two muskets were successfully shot, and the iron beads hit nearly 500 steps away. If Zhao Ying hadn't had the poisonous eyes, he might not have found the iron ball that was five hundred steps away.

"I'll ask you to improve the musket." Zhao Huan looked at the blasting musket and shook his head repeatedly.

Rome was not built in one day, nor was it invented in three weeks.

After Zhao Huan's gunpowder released a terrifying sound of lightning and thunder in Bianjing, his name suddenly reincarnated from Yan Luo and rose to the status of the immortal descending to the mortal world.

【System upgrade successfully.】

When Zhao Huan returned to the Bianjing Palace, the sudden system prompt subtitles made Zhao Huan stunned.

This system was approved for ten hours to upgrade, but it took three weeks to upgrade, and it was not until today that it was completely upgraded successfully.

Is your ten hours a day in the United States? So long? Zhao Huan said complaining.

He thought that his system would be upgraded and he would be eliminated.

[During the upgrade process, some errors occurred. Most of the pre-loaded modules failed to load, so they took a long time. After consuming the soul power of Song Qinzong Zhao Huan, they still failed to successfully smuggle. Sorry.]

The system’s reminder surprised Zhao Huan very much. When did the system learn to apologize?

Every day, he looks like he looks like the nostrils facing the sky, the second, the third, and the third, suddenly apologizes?

[The system for training civil officials and military officials failed to start.]

[The national official supervision system failed to be opened.]

[The state virtual deduction system failed to be turned on.]

[Beast Mount Training System failed to be turned on.]

[The Emperor's Immortal Cultivation System failed to be enabled.]

...

Zhao Huan looked at the long row of reminders and knew that the system was really working hard to enable various modules to cheat him.

Unfortunately, all of them failed to turn on.

This is not the first time.

Zhao Huan was not too disappointed. These cool systems had already passed by him once, and this time they passed by him again.

That's just a big deal! So distressing!
