As long as Li Zhongyi thinks of the dozen or so old craftsmen who were inadvertently killed, he doesn't want to mention how sad he is, in terms of his current state, it can be said that it is difficult to find a craftsman in a thousand armies. Pen, fun, and www.biquge.info

Although Li Zhongyi is a famous doctor and does understand some chemical principles, he is not an expert in gunpowder after all.

As the saying goes, interlacing is like separating mountains, Li Zhongyi knows the ratio scheme of black * fire * medicine, which is still the impression obtained from reading miscellaneous books.

As for how to get T*N*T, LI ZHONGYI really didn't understand, he only knew that during the First Sino-Japanese Naval War, the Japanese army used nitrate*glycerine*oil, which was very unstable.

Fireworks are strictly forbidden in the process of manufacturing and storing gunpowder, which is the basic safety common sense, and for this reason, Li Zhongyi personally formulated extremely strict operating regulations, and no one in the army dared to disobey them.

As the old saying goes, if you are backward in concept, you will suffer. Who would have imagined that in order to test the explosion effect more realistically, there were not only carriages and other debris at the scene, but also some people inadvertently stuffed the lard used for cooking under the carriage, and the result was that the power of the explosion exceeded the safe evasion distance marked by Li Zhongyi, and more than a dozen old craftsmen were killed by the flying rubble on the spot.

At first, everyone didn't know the truth that the power suddenly exploded several times, but later, Li Zhongyi found a suspicious point from the detailed interrogation record of the Judge Advocate General's Department: refined lard.

After Li Zhongyi determined the target, he personally led people to repeatedly experiment and make a detailed record of the steps, and finally determined: The refined lard should contain some special ingredient that can double the power.

Since it was on the way to the battle, Li Zhongyi didn't have much time and energy to study it personally, what are the necessary ingredients in lard?

However, Li Zhongyi is from a professional class after all, and he is vaguely aware that the refined lard should contain glycerin, and glycerin, oil and sulfur acid, after a suitable ratio, are important raw materials for nitric acid and glycerin.

In the past, in order to fool Chai Rong, Li Zhongyi used green alum (ferrous sulfate) to extract concentrated sulfuric acid. It's just that Li Zhongyi doesn't know how to refine sweet * oil, and there is no way to talk about nitric * acid * glycer* oil.

This time, the huge loss of more than a dozen old craftsmen can be said to be the loss of horses, and in front of Li Zhongyi, a door to Wilberland's experiment was suddenly opened.

At the briefing of the deployment meeting, which lasted for more than an hour, Yang Wushuang read out the military battle plan on behalf of the Senate Division, and he listed the number of days of remaining support for grain stock, how long the horse material could be supported, how many battles the bow and crossbow could handle, the production progress of the counterweight trebuchet, and the specific team leader, the focus of the tasks at the time of the battle was not only all-encompassing but also extremely detailed.

Sun Tzu said: Soldiers are impermanent, water is impermanent, and this requires adapting measures to local conditions.

When fighting against the powerful Khitans, the heavy and huge combat tool of the counterweight trebuchet was completely out of Li Zhongyi's consideration.

Whether it is the Dangxiang clan or the Khitans, they are all a people on horseback, and their strategic advantages determine that they emphasize a high degree of mobility and the ability to assault in battle, and the return artillery, which still seems cumbersome, is useless.

However, this time, Li Jiajun was facing the Goryeo rebel army, which was dominated by the infantry army, and the positional battle was obviously unavoidable, so the return artillery that Li Zhongyi had considered a long time ago was naturally put on the table.

Although the Central Plains regimes in the past dynasties were able to create powerful stone-throwing tools, they were only suitable for ship-borne or protracted siege warfare because of their very heavy and large size.

The principle of the return cannon is actually not complicated, and its core technology is the counterweight projectile. Unfortunately, before the advent of the Huihui Cannon, the craftsmen of the Central Plains Dynasty did not realize the key factor of counterweight throwing.

It is really a pity that gunpowder and fire* guns were first invented by the Chinese, but explosives and artillery technology were carried forward in Europe and used by the British to conquer the East.

Although the Senate Division's plan was already very detailed, Liao Shanhe still put forward additional opinions during the free discussion.

"Chief, colleagues, I think we should try our best to attract the Goryeo rebels out of Kaegyo, and at the same time arrange for the cavalry to outflank the city gate in advance to reduce the casualties of the soldiers in the streets and alleys." Liao Shanhe sighed, "After taking Yuguan last time, our army lost dozens of brothers in vain, alas, it's a pity, they are all battle-hardened warriors." I must remind my colleagues that in the narrow streets and alleys, the cold arrows shot by the Khitans hiding in the shadows are indeed unguardable. ”

When Li Zhongyi heard this, he couldn't help nodding frequently, what Liao Shanhe said was right, it was very reasonable.

Street fighting since ancient times has been a big headache for attackers who want to minimize casualties.

Due to the restrictions of the establishment of the forbidden army, Li Zhongyi has always adopted flexible methods in order not to hinder the eyes of the imperial court, and has always used the method of training non-commissioned officers or low-level officers to train ordinary soldiers.

The advantage of doing this is obvious: it is not conspicuous on weekdays, and once the situation develops, Li Jiajun's army can quickly expand its army without too much affecting the combat effectiveness of the troops.

There are pros and cons to everything, but the big trouble that comes with it is that the loss of more than ten excellent soldiers who are competent enough to perform the heavy duties of non-commissioned officers and literate is enough to make Li Zhongyi feel abnormal pain.

Just when Li Zhongyi was a little nostalgic, Song Yunxiang stared intently at Liao Shanhe's body, the mountain chief, Liao Shanhe actually called Li Zhongyi like this, which somewhat surprised Song Yunxiang.

In the past, everyone basically followed Li Zhongyi in different time periods, or called Lingshuai, or Xiangshuai, or Xiangshuai, or Xiangshuai, which can be described as diverse, and it seems that there are many mountains.

Today, Liao Shanhe has set a precedent for high-ranking generals, which is particularly eye-catching.

Song Yunxiang thought about it carefully, the title of the mountain chief was actually much weaker than the Lingshuai he had called before, and the factional color did seem much weaker, and it highlighted Li Zhongyi's status as a teacher and elder.

Holding benevolence, righteousness, propriety, wisdom and faith, respecting heaven and earth, and respecting the prince and teacher of heaven and earth is the way of humanity!

Disciples, teachers, respect for the father! Father, Father! The sovereign father, the lord also!

After Song Yunxiang figured out this layer of logic, he couldn't help but admire Liao Shanhe's keen nerves, and when Liao Shanhe was dry-mouthed, he decisively interjected and said: "Mountain Chief, everyone, I think that since there are five tunnels, instead of all of them being used to bombard the wall, it is better to calculate the layout of the Goryeo stick overnight, and when the time is ripe, come to the middle to bloom, hehe, that effect must not be much worse than collapsing the capital wall, right?" ”

"Huh......"

"Nourishing ......"

"Wonderful......"

"Clever ......"

"Great, great......"

As soon as Song Yunxiang's idea was proposed, it immediately attracted a round of applause from everyone, and words of admiration were endless.

Li Zhongyi touched his chin and looked at Song Yunxiang very interestingly, when Liao Shanhe called out the mountain chief, although he heard it, he didn't particularly care.

In the era when Li Zhongyi was the vice president, the principal (Shanchang) on the Internet basically referred to Chang Kaishen, President Chang, and it was certainly not a compliment.

Now, Song Yunxiang followed behind Liao Shanhe and shouted the word mountain chief, which attracted Li Zhongyi's attention.

The fortress is always breached from the inside, and with Li Zhongyi's current power and status, the biggest threat to him is actually the major mountains in the Li family's army, uniting to fight against his master.

To tell the truth, Li Zhongyi also tabooed the expansion of a certain hilltop power in the army to an uncontrollable extent, so supervision systems such as the Military Judge Advocate General's Department and the Suppression and Pacification came into being, the purpose of which was to check and balance the power and ambition of the military leaders.

"Mountain Chief, the students thought that they should divide two groups of cavalry, and when the coffin bullets were ignited, they would immediately kill from both wings to expand the results in time." Liu Heyang not only shouted out the mountain chief, but also regarded himself as a student, which couldn't help but surprise Liao Shanhe and others.

Li Zhongyi smiled, and after thinking about it, he felt a little ridiculous, which immediately reminded him of a classic movie scene.

"Of all of you here, have you brought an infantry drill code?" The principal suddenly asked, and for a moment everyone was dumbfounded, and everyone looked at each other, and no one was at a loss.

"Report to the principal, student Ember has brought it." A certain sycophant was good at seeing everyone, and easily took out the so-called infantry drill code from his pocket, and shook it towards everyone.

The giants in the army shouted out the mountain chief one after another, and regarded themselves as students, which was equivalent to a formal occasion and confirmed the teacher-student relationship.

In fact, Li Zhongyi spent a lot of time teaching in the lecture hall, and before that, only low-level officers called Li Zhongyi by the head of the mountain.

After several hours of deliberation, Li Zhongyi made a final battle plan, and the Senate Department urgently produced the text, which was quickly distributed to the officers of the team at the same level.

In the early morning of the second day, the loud wake-up bugle sounded at the right time, waking Li Zhongyi from his slumber.

After washing, Li Zhongyi ate a few pancakes with mutton soup, and dressed Mingguang armor neatly under the service of Zhu Niang.

Outside the big tent of the Chinese army, the "blood killing" led by the tooth soldiers, as soon as he saw Li Zhongyi walking out of the tent, he spewed out a loud nose, shook his head and tail with joy, and rubbed against the master's body.

Li Zhongyi stroked the long mane of "Blood Killing" with a smile, and said with a smile: "Blood kills my son, let's go to see blood again today, do you like it?" ”

"Xi Yoyo ......" bloody slaughter suddenly rushed to the front two front hooves, viciously kicked into the air, and escaped the unrivaled momentum of the horse stepping on the world.

Li Zhongyi smiled and nodded, and under the support of the tooth soldiers, he turned over and rode on the back of the bloody killing, looked around him, and shouted: "Sons, kill the enemy with me!" ”

"Kill, kill......"

"Kill the Stick ......"

"Grabbing the ......" has an eyeless tooth soldier, who is simply a flurry head, and actually shouted the slogan of the Sanguang sticks arrogantly in front of Li Zhongyi.

PS: Don't say much, Sikong continued to code the word to rush the draft, asking for a few monthly passes for encouragement, thank you!
