Daming: Grandpa Emperor, please get up and sit on my throne!

What he didn't expect was.

My own master actually miscalculated! This shouldn't be possible!

Monk Jingru shook his head: "I'm not quite sure about this...but as for His Majesty King Zhou, there's nothing I can do."

"I have to go back to Peking quickly." The wandering monk looked nervous, pondered for a moment, and said anxiously.

Monk Jingru didn't say much.

He just stood there quietly, clasping his hands together and saying, "Amitabha."

The wandering monk returned a perfunctory Buddhist salute and then left.

Watching the other person's back as he walks away.

Monk Jingru murmured meaningfully, "Perhaps this isn't God's will. Daoyan, your wisdom is inherently deeper than anyone else's. Why are you so obsessed with this?"

……

Zhu Yunhuan did not get the news about what was happening in the temple outside Yingtian Prefecture. After all, his Jinyiwei were not omnipotent.

Who could have imagined.

Would an inconspicuous wandering monk come here to spy?

Besides, everything the other party did was logical.

but.

He also has his own things to do.

The very next day.

A deafening sound rang out in the Forbidden City, breaking the solemnity and tranquility: "Bang——"

"What...what is going on?"

"This sound seems to come from the Qianqing Palace?"

"what happened?"

"It's over! Go check it out! Hurry and check it out!"

"..."

As this voice sounded, the entire Forbidden City suddenly became chaotic, and countless palace servants felt insecure.

however.

Just when the Forbidden City was in chaos because of this.

Inside the Qianqing Palace, Zhu Yunhuan stood in the backyard, looking at a side room in the distance that was emitting smoke, with a smile full of accomplishment on his face: "It's done!"

Ma Sanbao, standing nearby, patted his chest in shock and said worriedly, "Your Majesty...you, what are you doing? This is too dangerous! You are the Son of Heaven, a person worth millions! You must not make even the slightest mistake!"

Zhu Yunhuan raised his eyebrows indifferently.

He listened attentively to the panicked sounds outside and immediately instructed Ma Sanbao, "Go outside and calm the situation down. Just say that I was refining the elixir and the furnace just exploded. Don't let them get alarmed."

Ma Sanbao said hesitantly: "Then... this..."

Zhu Yunhuan immediately ordered without hesitation: "This is an imperial decree, go."

Ma Sanbao had no choice but to do as he was told.

Zhu Yunhuan stretched lazily, then squatted down to look at the lush sweet potato leaves. He said with a smile, "I've finally succeeded in making single-base gunpowder. Now I just have to wait for you to grow."

That's right, there was an explosion just now.

This is the result of Zhu Yunhuan's experiment.

Since he ascended the throne, he has been busy with other things. After all, winter is about to come, and he has to give priority to dealing with it.

Now everything is arranged.

The mines in various places are washing coal and transporting anthracite to coal transportation points in various provinces and prefectures. Water-powered spinning machines are producing a stable output of silk thread to the Ministry of Industry, which is responsible for weaving. The sweet potato vines have been planted for more than a month and there have been no major problems.

Zhu Yunhuan naturally had his hands free to do other things.

gunpowder!

Of course, Zhu Yunhuan would never use this kind of thing against his own people unless he had to. Even if he had a quarrel with the vassal kings or even some Huaixi nobles in the future, if he used this kind of thing, it would hurt the foundation of the Ming Dynasty.

Of course this thing should be used externally.

Although the Ming Dynasty was now a powerful military power, with many vassal kings guarding the three lines of defense and an all-star lineup of generals such as Lan Yu, the Central Plains was vast and prosperous, and the remnants of the Yuan Dynasty in the north, the Japanese pirates at sea, Yunnan, and Tubo...

Twenty-five years since the founding of the Ming Dynasty.

Wars, big and small, have never stopped.

Zhu Yunhuan wanted to do too many things, not just survive this winter, but this required the Ming Dynasty to be strong and developed internally. To defend the country internally, one must first stabilize the external situation. If one wanted to vigorously develop the people's livelihood and economy of the Ming Dynasty, the Ming Dynasty could not be in a situation where large or small battles could occur at any time.

To achieve this condition.

Then we have to defeat the monsters and demons around us first.

With the current military strength of the Ming Dynasty, Zhu Yuanzhang had been unable to fully achieve this goal after 25 years of efforts. In terms of military affairs, Zhu Yunhuan would not be arrogant enough to think that he could do better than Zhu Yuanzhang with the same military strength and combat power.

Fortunately.

He has another way.

Gunpowder had actually been invented a long time ago.

The earliest gunpowder was traditional gunpowder made from potassium nitrate, sulfur, and carbon in a certain proportion. It can also be called black powder. Unfortunately, China's technology tree went astray, and they only wanted to use gunpowder as firecrackers.

Even at this stage, there has not been much progress in the formula of gunpowder, and even single-base gunpowder has not yet been developed.

Single-base gunpowder, also known as nitrocellulose gunpowder.

The principle of its production is to soak cotton in nitric acid, nitrate it, and then dissolve it with ethanol (alcohol) to achieve dry and hardening. This is a single-base gunpowder.

Compared to ordinary black powder.

The power is greatly enhanced.

Zhu Yunhuan stood up and looked intently at his own Qianqing Palace, where a room had been blown up, with a faint smile on his lips: "Since the preliminary experiment was successful, the next step is large-scale production..."

"For large-scale production, we need to find some guys who understand chemistry..." Zhu Yunhuan murmured thoughtfully. After all, he had too many things to deal with. Small-scale production was no problem, but he had neither the time nor the energy for mass production.

After thinking for a moment, his eyes lit up: "Then I will refine more pills!"
