And this drying time takes about two to three weeks. After all, it is not high-temperature drying, but room temperature ventilation drying, and moisture must be detected.

Of course, during this time, Zhao Huan didn't plan to be idle, and on the first day, he made a weight balance to use.

The stereotype said that it was a little troublesome to use, and after the weight balance was ready, Zhao Huan's smile was like a child's Akagi.

Men's happiness is sometimes really simple.

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

And Zhang Tanghua didn't feel anything about it, just staying by Zhao Huan's side was enough.

She knew what the officials liked.

Zhao Huan returned to the palace late at night, and went to the ordnance prison the next day.

He himself likes handicrafts very much, and in the Ordnance Prison, he made a steam ball by himself.

When the ball was spinning rapidly on the shelf, Zhang Tanghua watched it intently for a long time, but he still didn't understand what the use of this was.

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

Zhang Tanghua solemnly put away the steam ball, this is a gift made by Zhao Huan himself, is there anything more precious than this?

Zhao Huan went to the Ordnance Prison a few days later, and he never took Zhang Tanghua with him 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 back to Zhu Lian was a very ordinary transparent water cup.

And this water cup is the glass that Zhao Huan burned out of sand in the past few days, transparent and clear, like a crystal-like glass.

Of course, this is also what Zhao Huan did.

The appearance of glass is a gift made by an official family for Zhu Lian, but Zhao Huan knows that the significance of glass is very important, the origin of optical instruments, and the beginning of chemical experiments.

Moreover, it marks that the alchemist's rough and unrestrained experimental style has officially stepped into the right track and accurate measurement.

Beakers, measuring cups, flasks, Erlenmeyer flasks, funnels, jars, flasks, evaporators, and a host of other objects appear within two to three weeks.

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

He's not playing, he's laying the foundation for Da Song's chemical industry. Instruments and precision are the incubators of the chemical industry.

In the past three weeks in the Ordnance Prison, Zhao Huan finally had enough of his handicraft addiction, and it was finally time for gunpowder acceptance.

Zhao Huan and Chen Gui stayed outside the bakery, anxiously waiting for the gunpowder to come out, and even ate at the ordnance superintendent.

"Can the official family do it?" With some trepidation, he took the gunpowder out of the drying room, inserted all the gunpowder into the twist and iron sheet, and loaded the musket again, but the old rule still had some doubts.

"Try to keep the lead as long as possible, we're all farther away."

Zhao Huan felt that it should be okay to be five or six zhang away, but after thinking about it, he still moved back five or six zhang.

"Let's get started. Click and run. Zhao Huan told the pro-servant who went to light the fuse and said.

The official nodded yes, he lit the fuse, and when he spread his feet and ran back to Zhao Huan, the gunpowder fuse was still about halfway, and it was really fast.

A few pro-officials stood in front of the officials and many ministers.

"Bang!"

There was a sound like thunder, followed by a tinkling sound as dense as rain, the sound of iron pieces stuck in gunpowder, and the sound of human armor.

Around the powder table were several shelves on which stepped armor were placed for reference to the results of the experiment.

The sound of the dense metal colliding was the sound of the countless pieces of iron and the infantry armor in the tribulus cannon.

After this thunder and the continuous sound of heavy rain, everyone looked left and right in amazement, not knowing what to do.

It was so loud that it caught them off guard.

Zhao Huan took out two lumps of cotton from his ears in a good time, he already knew that there would be a loud noise, so he had already blocked his ears.

At a distance of more than thirty meters, there were still pieces of iron inlaid on the wooden canopy held by the official Zhao Huan looked at the depth and secretly said.

On the test site, there was still a large amount of gunpowder smoke filling it, and this thunder was even heard in Bianjing City.

Zhao Huan waited for the smoke to dissipate, and saw that the surface of the Buren's armor was full of potholes.

There were even pieces of iron that passed through the weak points of the foot armor.

Broken defenses.

Zhao Huan smiled happily and said, "It looks like the power is good." ”

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

The recipe provided by Zhao Huan was not even a method for making compressed gunpowder, and the power was only about a quarter of that of TNT of the same weight.

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

The medicine cake is grinded by the old rules, the gunpowder is made by the old rules, the old rules looked at their hands in disbelief, what did they make?

Zhao Ying waited for a long time before entering the test site, and he wanted to count the damage to the Buren Armor so that he could adjust the power of the gunpowder bag.

"The official family, the twenty-three foot armor, all the armor at the head of the armor, have been pierced, and most of the pockets have been pierced. The innermost four pieces of foot armor pierced the breastplate. It's powerful. Zhao Ying returned to the official's side.

The reason why he waited until the smoke cleared, and waited for a long time to go, was because he was afraid that some of the pills would not detonate.

This is something that the official family has told him thousands of times, where does Zhao Ying dare to forget?

"The official family is really a god descending from heaven!" Zhao Ying sighed with heartfelt emotion.

Li Gang and the others thought of the rumors of Zhao Huan Yanluo's reincarnation, and they couldn't stop nodding, it must be the immortal god who descended to earth, otherwise just a piece of paper can create such a human killing weapon?

"Let the musketeers try it." Zhao Huan thought for a while and said, "This is the first experiment, you should be careful." Let's all leave. ”

If the gunpowder of the thistle cannon is extremely successful, the black powder of the firing powder is also very cool, and almost all of them are blown up.

When the power is several times greater, continuing to use bamboo poles is really humiliating gunpowder.

Only two muskets were successfully fired, and the iron ball was shot out at a distance of nearly five hundred steps, if it weren't for Zhao Ying's poisonous eyes, maybe he wouldn't be able to find the iron ball five hundred steps away.

"I'll leave it to you to improve the musket." Zhao Huan looked at the exploding musket and shook his head again and again.

Rome wasn't built in a day, and flintlock pistols weren't invented in three weeks.

After Zhao Huan's gunpowder released a terrifying sound in Bianjing that was no less than lightning and thunder, his name suddenly reincarnated from Yama and rose to the status of an immortal.

[The system upgrade is successful.] 】

When Zhao Huan returned to the Bianjing Palace, the subtitles prompted by the system suddenly appeared, which made Zhao Huan stunned.

The system was upgraded for ten hours, but it took three weeks to upgrade, and it was not until today that the upgrade was complete.

Is this 10 hours of American time for you? So long? Zhao Huan said complainingly.

He also thought that his system had been upgraded and that he had lost his name.

[During the upgrade process, there were some errors, and most of the modules that were preloaded failed to load, so it took a long time. After consuming the soul power of Song Qinzong Zhao Huan, he still failed to succeed in smuggling. I'm so sorry. 】

The system's reminder made Zhao Huan extremely surprised, when did the system learn to apologize?

Every day, a pair of nostrils to the sky, the eldest of the sky, the second of the earth, the third of its appearance, suddenly apologize?

[The Wenchen military general training system failed to open. 】

[The national official supervision system has failed. 】

[The virtual deduction system for state affairs failed to be opened. 】

[Beast mount cultivation system failed to be activated.] 】

[The Emperor's Immortal Cultivation System failed to be opened. 】

……

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

Unfortunately, all of them failed.

This is not the first time.

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

That's a fart! It's so distressing!

"Great Emperor System, what have you upgraded?" Zhao Huan scratched his head and asked.
