Gunpowder, it seems that in the three generations, the Yin and Yang family remained, and there were often Yin and Yang family alchemists who didn't know what to add when they were alchemizing.

Suddenly, the entire alchemy furnace burst open.

Later, in order to avoid such trouble, after careful study, those things that could easily cause the alchemy furnace to burst were recorded and listed as forbidden things.

There's a lot of content to be included, and it's not just like the years.

Zhou Qing had also left some information in the Arsenal Hall of the Protectorate Palace before, and he didn't ...... much, after all, it was done directly overnight, and many processes were skipped, and many good things might be missed.

Later, the volume of forbidden things obtained from yin and yang was sent to the armory hall, and now it is ...... Something in front of me appeared, which was interesting, and looked like a mortar in the long river of years.

In fact, it is a powerful crossbow!

With a powerful propulsion, shoot a giant crossbow containing simple gunpowder, and the moment it is fired, it ...... The high temperature inside the giant crossbow caused the ignition to ignite, and the giant crossbow burst open for it.

The farthest distance can reach two or three hundred feet, but that requires excellent elasticity!

Ordinary crossbows, beyond a hundred zhang, the power is still considerable.

"Wu Zhenhou!"

"Recently, the courtyard is developing another more powerful thing, which is to wear this giant crossbow with six small crossbow arrows, which are also filled with bursts."

"When the giant crossbow flies, it will automatically fly around, and its power is also very great, and the coverage is also wider."

Hearing this, among the people on Zhou Qing's side, a man who was dressed in strength walked out quickly, not like an official and dignitary of the Protector Palace, bowed his hand, and said how to go further.

"How long will it take?"

The meaning of what the other party said is not difficult to understand, and for Zhou Qing, it is even more so, in the long years, he has seen more ballistas.

"It will be developed this year."

The man hurriedly responded.

"It's a great achievement."

"However, you should know whether this kind of thing, the weapon of the country, is important, if the news of this thing spreads, according to the rules of the Armory Academy."

"You should know what happened!"

Zhou Qing's head is that there will be smart people in any era, as long as he is given enough time and knowledge to make better things, it will be easy.

Although things like crossbows were developed, they did not really fall on the battlefields of the Shandong countries.

Otherwise, it appeared rashly, with the ability of a hundred schools, Zhou Qing didn't think that the Protectorate Palace could be preserved for a long time, so he either didn't use it or used it on the blade.

Confidentiality is especially important!

This time, I came here to see the power of the crossbow, and even the core of the school palace, Huan Qi, is in the future.

"Whoa!"

The man shuddered and bowed deeply again.

The Arsenal Hall is in the Nine Courtyards of the Protectorate Palace, and its status is very unusual, and Lu Shi can be one of the best in the Academy, but the laws in the Palace are also one of the strictest.

The slightest mistake is a felony!

When it comes to news leakage, it is even more consequential and extermination!

But...... There are also great benefits, if there is a great merit, you can recommend students to enter the National Academy of Learning, as a reward, this kind of reward may not have been obvious a few years ago.

Right now...... Valuable!

"Starting next year, the students recruited by the Armory Academy will be more complicated, and Xianyang will send special personnel to review them, and what you and others have done has always been in the eyes of the king."

"Although you don't enter the battlefield, with this thing alone, the merit is inferior to killing the enemy on the battlefield!"

The examination of the students of the Guardian Academy is carried out every year, and the human, material, and financial resources consumed every year are ...... Needless to say, it's definitely huge.

Of course, it's well worth it.

Many spies from hundreds of schools and Shandong countries were dug up.

End ...... It didn't spread.

Despite this, Zhou Qing felt that there should be something deeper hidden in the Protectorate Palace.

"Give a numbered book, every other period, regular counting, and there shall be no mistakes."

"In addition, take two planes back to Xianyang, let the king take a look, and name them!"

It's still possible in terms of power.

During this period of time, Zhou Qing felt that there was not much he could do, but everything was slowly progressing.

Looking at the ten crossbows displayed not far away, he ordered directly.

"Whoa!"

The people on the side did not dare to be suspicious, and saluted again, and then ordered to go down, and after a while, the group quietly left here, and the traces and remnants left on the foothills of the crossbow were also wiped out.

******

"Wu Zhenhou!"

“……”

Xue Gong Cheng Huan Qi led the core doctors of the nine courtyards to salute in the side hall of the lecture hall, wearing the formal clothes of the Xue Palace, all kinds of etiquette, did not dare to exceed.

"No need to be polite."

"Ben Hou returned to Xianyang this time, and the school palace is here for the second time, very good, everything is not much different from what Ben Hou expected at the beginning, although there are also a lot of problems, which are all you have to deal with."

After a few years, Huan Qi is still a scholar and does not hold the position of the big sacrificial wine.

Seemingly...... For a general who has suffered a great defeat, it is difficult for Brother Wang to hold the position of the great sacrificial wine of the Protector Palace, which is becoming more and more important today.

The lieutenant is still part-time!

The things in the Central School Palace are much easier to deal with, and Cai Ze, who has just become a king, handles it very well, and lives very comfortably, of course, in terms of the promotion of the title, the Protector School Palace is faster.

It seems that Cai Ze, who has just become a gentleman, has no opinions, and he is old and has not much life.

The Palace of Guardian Studies is here...... It has gradually become more complicated, everything in the nine courtyards is on the right track, all regulations have gradually matured, and there are precedents to follow for the selection, appointment, and dispatch of students.

Nature...... After a set of rules and systems mature, someone will drill holes and drill gaps!

It's inevitable.

Between heaven and earth, there is no truly perfect thing, and the Protector Palace is no exception.

"Wu Zhenhou's eyes are like torches, and the Protector Palace still needs the teachings of Wu Zhenhou."

The beard is gray, and the school palace is now content, although it is difficult to be promoted to the great sacrifice wine in this life, but the title has been promoted, and it is better than nothing.

Besides, for a general of a defeated army, what is the king dissatisfied with being able to give himself such an opportunity?

"You all step down, Ben Hou and Xuegong Cheng have important matters to discuss."

Zhou Qing paced in the hall, smiled when he heard this, waved his hand, and looked at the person who was a doctor in the courtyard, the power of spiritual consciousness spread, and the school palace was at this moment.

All the academies are training, no matter which academy, physical fitness and physique are the first, every year's assessment is like this, if the physical fitness is not good, the assessment score will be very low.

"Whoa!"

“……”

The doctor of the Nine Great Courtyards saluted, did not dare to ask more, and slowly retreated, leaving this side hall.

"How's Childe doing?"

"Is there anything wrong with the Academy?"

Since this year, all kinds of things have happened in the Xianyang Palace, and the Confucian Fu Nian has returned to the small sage village in Songhai, and the son Tianming has left the Xianyang Palace.

Since then, the place of teaching in the Xianyang Palace does not exist, and the son Fusu, who was also taught in it, went to the Huguo Palace, and the time was ...... It's about the time when the Protector Academy is recruited every year.

It didn't cause anyone's surprise, and no one knew about the fake name used by Fusu.

Maybe the age is a little worse, according to the regulations of the Protector Palace, if you want to enter the palace, you have to be at least seventeen years old, and three years later, twenty years old, just in the army.

Fusu Gongzi has learned martial arts since he was a child, his muscles and bones are strong, and there seems to be nothing wrong with him, and in the entire Protector Palace, there are only two people who know Fusu's identity.

One is the captain of the country, and he is added as a big sacrificial wine!

One is Xue Gong Cheng Huan Qi!

"Childe's Kana Hashimatsu, he has entered the scheming academy, and he has adapted very well now, and there is nothing wrong with him."

"Haha, but at the beginning, Childe may have been used to sleeping alone, but it caused a little laughter, but after half a month, it was not obvious."

Guanwu Zhenhou avoided the doctor of the Nine Great Courtyards, Huan Qi already expected it in his heart, and when he heard this, it really involved Gongzi, but ...... The identity of the prince is precious, not to mention the eldest son of the king.

Although he is not a concubine, the king has not set up a queen, so since the Great Zhou patriarchy, Gongzi Fusu is the most likely to inherit the crown prince and even the throne in the future.

"There is Fusu in the mountains, and there is Hehua in the Xi. I don't see the son, but I see madness. ”

"There are bridges and pines in the mountains, and there are swimming dragons in the mountains. I don't see Zichong, but I see a cunning child. ”

"The name Qiao Song should be made up by the son, let's go, follow Benhou to the conspiracy courtyard, and discuss some interesting things in detail on Benhou Road."

Zhou Qing also smiled, since ancient times, the teachings of the son are the most top-notch and noble, Brother Wang said a few years ago, all the sons of the knees must go to the two university palaces to experience.

As for how to experience, there is not much to say.

Fusu was able to enter under a pseudonym, and he thought that he had also passed through Brother Wang, and he would not miss it if he touched the shadow guard, and under the spiritual awareness just now, there were also people from the shadow guard in the scheming courtyard.

Of course, Miyamoto, the protector of the country, is also the place where the reserve personnel of the shadow secret guard are located.

"Whoa!"

For Gongzi Fusu's attention, Huan Qi is naturally also concerned, otherwise in the Protectorate Palace, if Gongzi is injured in something, it will be his own sin.

Out of the side hall of the martial arts hall, facing the hot sun, he had been waiting for the guards of the school palace outside the hall to salute, and wanted to follow, and then, he was waved by Zhou Qing and retreated.

"Let these green trees grow like this, and don't cut them down at will."

"They appear here with the school palace, and they should grow together with the school palace, the forest has been in the forest for thousands of years, and the school palace has also continued for thousands of years."

"Why do you think of the Academy?"

The boulevard is wide and flat, there is not a trace of dust on it, the heat wave hits, even if the trees are shady, it is only relieved, and when you look around, it is a familiar feeling.

In the past few years, the trees in it have grown vigorously, the branches are straight, the green leaves are stretched, and there is a special person to support it, Zhou Qing's eyes swept over those, and he sighed.
