Whenever Li Zhongyi thinks of the dozen old craftsmen who were accidentally killed, he feels so sad. As for his current state, it is easy to get a craftsman.

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

As the saying goes, "Across the roads are like a mountain". Li Zhongyi knows the ratio of black *fire* medicine, so he is still the impression he gets from reading miscellaneous books.

As for how to do t*n*t, Li Zhongyi really didn't understand it. He only knew that during the Sino-Japanese War of 1894-1895, the Japanese army used nitro*gly*gly*oil with very poor stability.

The manufacturing and storage of fire medicines is strictly prohibited, which is a basic safety common sense. For this reason, Li Zhongyi personally formulated extremely harsh operating regulations, and no one in the army dared to violate them.

There should be the old saying that if you are backward, you will suffer. Who can imagine that in order to test the explosion effect more realistically, there were not only debris such as carriages on the scene, but also someone accidentally stuffed the lard for cooking under the carriage. As a result, the power of the explosion exceeded the safe distance Li Zhongyi determined, and more than a dozen old craftsmen were killed by flying gravel on the spot.

At first, no one knew the truth that the power suddenly increased several times. Later, Li Zhongyi found a doubt in the detailed interrogation record of the Military Justice Department: refined lard.

Big stones, carriages, and giant trees are all dead objects, and they cannot be related to the sudden increase in power. After Li Zhongyi determined the target, he personally led people to experiment repeatedly and made detailed steps. He finally determined that the refined lard should contain some special ingredients, which can double its power.

Since it was during the battle, Li Zhongyi didn’t have much time and energy to study what necessary ingredients contained in lard?

However, Li Zhongyi was a professional after all, and he vaguely realized that the refined lard should contain glycoside oil, and glycoside oil and sulfur acid were appropriately proportioned to be the important raw materials for nitric acid*glycemic*glycemic*glycemic*glycemic*glycemic*glycemic*glycemic*glycemic*glycemic*glycemic*glycemic.

In the past, in order to fool Chai Rong, Li Zhongyi used green alum (ferrous sulfate) to extract concentrated sulfuric acid. However, Li Zhongyi did not know how to extract sweet* oil, and there was no way to talk about nitro* acid*gly* oil.

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

At the more than an hour-long deployment meeting, Yang Wushuang read out the military combat plan on behalf of the Senate Office. He listed the number of days of remaining support for grain storage, how long can the horse material last, how many battles can the crossbow handle, the production progress of counterweight catapults, and until a specific team is in charge. The task focus during the battle is not only all-encompassing but also extremely detailed.

Sun Tzu said: The war has no constant shape and the water has no constant momentum. This requires adapting to local conditions.

When fighting against the Khitans with powerful motor power, the bulky and huge combat tool of the counterweight catapult was completely out of Li Zhongyi's consideration.

Whether it is the Dangxiang tribe or the Khitans, they are all ethnic groups on horseback, and their strategic advantages determine that they emphasize high maneuverability and attack ability on the front line. The Hui artillery, which still appears to be bulky, has no place to use it.

However, this time the Li family army faced the Goryeo rebel army, which was mainly infantry, and positional warfare was obviously inevitable. So the Hui artillery that Li Zhongyi had considered long ago was naturally placed on the table.

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

The principle of Huihui cannon is actually not complicated. Its core technology is counterweight parabolic parabolic. Unfortunately, before the advent of Huihui cannon, craftsmen of the Central Plains dynasties did not realize the key factor of counterweight parabolic parabolic.

Fire medicine and fire guns were both first invented by the Chinese. However, explosive medicine and artillery technology were promoted in Europe and were used by the British to conquer the East. This is really a pity.

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

"Master, my colleagues, I think I should attract the Goryeo rebels out of Kaijing as much as possible, and at the same time, the cavalry should be arranged in advance to surround the city gates to reduce the casualties of the soldiers in the streets and alleys." Liao Shanhe sighed, "After the last time we took Yu Pass, our army lost dozens of brothers in vain. Alas, what a pity, they are all war-hardened soldiers. I must remind you that the cold arrows shot by the Khitans hiding in the dark in the narrow streets and alleys are indeed unpredictable."

After hearing this, Li Zhongyi couldn't help but nodded frequently. Liao Shanhe said nothing wrong, which made a lot of sense.

Street fighting since ancient times has been a headache for the offensive party who wants to minimize casualties.

Due to the restrictions on the establishment of the imperial guards, Li Zhongyi has always adopted a flexible approach in order not to hinder the court's eyes and has always trained ordinary soldiers by training non-commissioned officers or low-level officers.

The advantage of doing this is obvious. It is not obvious that it is not visible in daily life. Once the situation develops, the Li family army can expand its army quickly without affecting the combat effectiveness of the troops too much.

Everything has its pros and cons, but the big trouble that comes with it is that excellent soldiers who are capable of performing the heavy responsibilities of non-commissioned officers and literacy lose more than ten each time, which is enough to make Li Zhongyi feel extremely painful.

Just when Li Zhongyi was a little moved, Song Yunxiang stared at Liao Shanhe with his eyes open. The mountain was the leader, and Liao Shanhe actually called Li Zhongyi so, which surprised Song Yunxiang a little.

In the past, people basically followed Li Zhongyi according to different periods of time, either called Lingshuai, Xiangshuai, or the Township, which was diverse and seemed to be full of mountains.

Now, Liao Shanhe has set a precedent for senior generals, which is particularly eye-catching.

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

Upholding benevolence, righteousness, propriety, wisdom and trustworthiness, respecting heaven, earth, king, parents and teachers is the ultimate way of human ethics!

Disciples serve teachers and respect them as their father! Fathers are kings and fathers! Kings and fathers are lords!

After Song Yunxiang figured out this logic, he couldn't help but admire Liao Shanhe's keen nerves. Taking advantage of Liao Shanhe's speech, he interrupted decisively: "Master, everyone, I think that since there are five authentic tunnels, instead of using them to bombard the wall, it's better to calculate the position of the Goryeo Rod overnight. When the time is ripe, there will be a flower in the middle. Hehe, that effect must not be much worse than the collapse of the capital wall, right?"

“Huh…”

"Si..."

"It's amazing..."

"A clever plan..."

“Great, great…”

Once Song Yunxiang's idea was proposed, it immediately attracted a lot of cheers from everyone and said endlessly.

Li Zhongyi touched his chin and looked at Song Yunxiang very interestingly. When Liao Shanhe called out the mountain leader, he didn't care much about it even though he heard it.

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

Now, Song Yunxiang followed Liao Shanhe and shouted the word "shanlong", which attracted Li Zhongyi's attention.

The fortress was always broken from the inside. With Li Zhongyi's current power and status, the biggest threat to him was that the major hills in the Li family army united to fight back on his master.

To be honest, Li Zhongyi also avoided the expansion of the force of a certain mountain in the army to an irresistible level, so supervision systems such as the Military Justice Department and the Punishment Department came into being, with the purpose of checking and balancing the forces and ambitions of the military leaders.

"The mountain commander, the students thought they should separate two cavalrymen. After the coffin bullet was ignited, they immediately broke out from both wings and expanded the results in time." Liu Heyang not only called out the mountain commander, but also regarded himself as a student, which surprised Liao Shanhe and others.

Li Zhongyi smiled and thought about it and then felt it was absurd, which immediately reminded him of a classic movie scene.

"Whoever is here, who has brought the infantry training?" The principal suddenly asked, and the seats were all dumb. Everyone looked at each other, and no one was confused.

"Report to the principal, the student Enbo has taken it." A flatterer took out the so-called infantry ritual from his pocket in front of everyone's eyes and shook it at everyone. It seemed that nothing was wrong, but it was very proud of it.

The giants in the army called out the mountain chief one after another and regarded themselves as students, which was equivalent to confirming the relationship between teachers and students on formal occasions.

In fact, Li Zhongyi spent a lot of time teaching in the martial arts lecture hall. Previously, only low-level officers called Li Zhongyi the mountain leader.

After several hours of discussion, Li Zhongyi made the final battle plan, and the Senate Department urgently prepared the text and quickly sent it to the hands of the officer at the level of the team.

In the early morning of the next day, the loud trumpet of getting up was blew at the right time, awakening Li Zhongyi from his sleep.

After washing up, Li Zhongyi ate a few pancakes with mutton soup, and under Zhu Niang's service, he dressed up Mingguang armor neatly.

Outside the central army's tent, the "blood killer" led by the tooth soldier, saw Li Zhongyi walking out of the tent, and squirted loudly, shook his head and tail happily, rubbing towards his master's body.

Li Zhongyi smiled and stroked the long mane of "Blood Kill" and said with a smile: "Blood Kill my son, we are going to see the blood again today. Do you like it?"

"Xi Liuliu..." Xue Sha suddenly exerted his two front hooves and rushed into the air fiercely, showing his unparalleled aura of riding the world.

Li Zhongyi nodded with a smile, and under the support of the fang soldier, he turned over and rode on the back of the blood-killed man. His eyes were surrounded by a circle and he shouted loudly: "My sons, follow me to kill the enemy!"

"Kill the enemy, kill the enemy..."

"Kill the stick..."

"Grab..." There was a young soldier who was blind and was simply a silly man. He actually shouted the slogans of the three light sticks in front of Li Zhongyi.
