The moon is on the top, and the night is coming again. After Jing Zetian said goodbye to Lin Yan in Wenyuan Pavilion, he immediately returned to Zhengyang Palace.

After a brief dinner, I lay down in a warm and comfortable bed.

After casually talking to Lin Yan for a while just now, after Lin Yan was still chatting with him, he quickly retreated. Lin Yan, an old guy, turned out to be a talker, which surprised Jing Zetian.

After getting rid of the distracting thoughts in his mind, Jing Zetian closed his eyes and continued to watch the joke every day.

Unlike usual, Jing Zetian had to ask Duan You for help again today.

"Ask for advice, what is the formula of gunpowder, Lao Tzu is going to blow up, the simpler it is, the better, as long as the momentum is big enough." Jing Zetian posted a message in the paragraph.

When robbing relatives, they were weak in strength, and no matter how they were arranged in the early stage, there were still many soldiers who escorted the family welcoming team.

For the sake of safety, Jing Zetian finally decided to use gunpowder to help him. The development of gunpowder was relatively slow, and it was only possible to make it at will in the Tang Dynasty, but the purpose of making it was mainly for firecrackers. Dahua followed closely behind the Three Kingdoms, Jing Zetian grew so big, and he had never seen firecrackers.

How to make gunpowder, Jing Zetian naturally didn't know, but he had a joke, he tried to ask in the joke to see if Duan You knew the formula of gunpowder, no need how powerful the gunpowder was, as long as it was loud enough. The soldiers in the welcoming procession all rode forward, and when there was an earth-shattering sound, the horses would definitely be frightened, and by taking this opportunity, their chances of robbing their relatives would be greatly increased.

"Wow, who are the six princes going to bomb?" Duan Youerha replied a little cutely.

"I have an ancestral secret recipe, if the six princes want it, give me a women's Pure Land of Bliss." Duan You said in black and white.

……

Duan You still said it first, and as for answering Jing Zetian's question, there was really no one.

However, Jing Zetian was not in a hurry, because every time he sought advice, it was 'difficult'.

"Wow, you don't even know about the Six Princes? Did you travel through the past without going to junior high school? The recipe of black powder is very simple, 'one sulfur, two nitrate, three charcoal'. The chemical equation 2KNO3 + S + 3C ==== K2S + N2 ↑+ 3CO2↑...... "The Duanyou volcanic explosion replied with a large string.

Finally, a professional Duan You replied to Jing Zetian at length, but Jing Zetian couldn't understand such a complicated thing.

It doesn't matter if you don't understand it, Jing Zetian has a shameless attitude of asking, directly pays attention to this Duan You, and then sends a private message.

"I want to make a pack of 100 catties of gunpowder, a total of 500 kilograms of gunpowder, what do you say the materials are needed and what is the specific gravity, I graduated from primary school." Jing Zetian directly sent a message about the volcanic explosion in the paragraph.

Soon, the volcanic explosion replied to Jing Zetian's news: "Saltpeter accounts for 50.6%, sulfur 26.6%, and carbon-containing substances 22.8%, be careful when you make it, don't blow yourself up, no one uses this recipe now, I also searched for it, you can do it." ”

Jing Zetian obtained this formula, it was like a treasure, and gunpowder was simply a plug-in in this era.

Looking at the formula, Jing Zetian began to worry about the materials again, these things are available now, but sulfur is very expensive, and he may not be able to afford it at his current price, but no matter how expensive it is, Jing Zetian has to find a way to make it.

When the goal was achieved, Jing Zetian's spirit suddenly relaxed, and his fatigue after a busy day of work instantly welled up, and in a moment, Jing Zetian fell into a deep sleep.

--- dividing line---

In Zhao's mansion, in Zhao Chongde's study, the candlelight flickered, dispelling a pure night.

As the patriarch of a big family, Zhao Chongde has to worry about managing the family's affairs in addition to handling the official affairs of the imperial court on weekdays.

Although there are many clansmen in the family who come to help manage it on weekdays, every night, after he is busy with official business, he habitually has to listen to the people in the house to report on today's work, so as to have an understanding of the overall situation of the family.

At this moment, in Zhao Chong's study, there was an old man standing in front of Zhao Chongde, reporting on his work during the day.

"Master, everything is fine in the house today, but speaking of which, there is one thing that is quite special." Zhao Wen, the housekeeper of the Zhao Mansion, said respectfully. Zhao Wen is a servant cultivated by the Zhao family itself, this kind of servant is very common in the major families, and is generally the most trusted existence of the main family. In addition to being raised from childhood, these people are generally slaves and have no personal freedom.

"Oh? What's the matter? Zhao Chongde, who was squinting his eyes and flipping through the letter by candlelight, asked casually.

"Today, the sixth prince is looking for the little master." The old servant Zhao Wen replied.

"Do you know what the six princes are looking for Su'er?" Zhao Chongde still looked at the letter casually, obviously this incident did not bring him much fluctuation.

"This old servant doesn't know that the six princes left after a simple meal in the mansion, and they didn't stay in the mansion for too long."

"Well, I see, is there anything else?"

"No, the old servant will retire." After Zhao Wen finished speaking, he bowed and retreated.

After Zhao Wen left, Zhao Chongde put the letter in his hand back on the table, got up and walked to the window, looking at the bright moon in the dark night, not knowing what he was thinking.

"Boom! Boom! Boom! "The morning bell rang again.

The whole earth was slowly awakened by the sound of the bells, and the flowers stretched out their branches, and the dew on the branches and leaves were gently flicked away, and in the sunlight, they were crystal clear.

The civil and military officials of Huaguo had already gotten up and were already waiting for the beginning of the early dynasty inside and outside the Qianyuan Palace.

Jing Kaige still stepped into the main hall, and after a simple greeting to the officials, the early dynasty began as usual.

"Your Majesty, the barbarians in Lingnan have started to stir up trouble again, and recently received a report from the local county order, since the beginning of spring, the barbarians have often come out of the mountains and forests to attack the people of my Dahua, and the officials of the counties near Lingnan have jointly written a letter asking Your Majesty to send troops to conquer these barbarians." Zuo Xianghou Wanjin was the first to stand up and report.

"What do you think?" Jing Kaige did not reply, and threw the question to the civil and military officials.

"Father, the son of the emperor asked to lead troops to pacify these barbarians, my Dahua is now short of manpower, and these barbarians are all taken into slavery." The crown prince Jing Zerun, who had just returned triumphantly, took the initiative to speak out when he was in high spirits.

"Yes, Your Majesty, now that the morale of my Dahua soldiers is high, Lingnan is the land of my Han people, and now that my Dahua has freed up my hands, it is time to take back these lands." General Zhengnan Gao Leng stood up and said.

Dahua's general system basically followed the Han system, but the general officer position was abolished, and it was generally a temporary appointment in important wars, in fact, it was generally a part-time job for the emperor of Dahua. General Zhengnan belongs to the four generals and the second-rank generals.

The responsibilities of the four generals are basically the same as their official names, and the generals of Zhengnan are generally responsible for military activities in the south, so at this time, Gao Leng spoke on behalf of the military, and the other generals were not in a hurry to come out to ask for battle.
