There must always be troops left at the end to block the attack of Fang La's army, so that the fleet can smoothly leave the shore.

Xunyang's infantry took over the order that was close to suicide, because Zhang Tianlei vouched for the well-being of his children and grandchildren, promising them that a high pension would be sent to their families.

Yu Yunwen was helped to the boat by Zhang Tianlei and sat down with a pendulum.

Turning back, Yu Yunwen saw that the Xunyang infantry who stuck to the end had suffered heavy casualties and might be wiped out, so he had an idea: "The Xunyang infantry fought to the death for the country, and there should be no such casualties." ”

"Order the warship to approach the river beach, throw all the remaining firearms at Fang Lajun, and save the Xunyang infantry soldiers!"

Zhang Tianlei was so excited that with tears in his eyes, he knelt down on one knee and said: "Bid for Xunyang's father, thank you Lord Yu!" ”

After two incense sticks, the warship carrying firearms approached the river beach, and threw all the remaining firearms into the frantically pursuing Fangla army formation by using the ship's bed, crossbow, catapult, and other ordnance.

Xunyang's foot soldiers, who had suffered most casualties, did not hesitate at all after receiving the military order for the whole army to withdraw into the water, and rushed to the river, dipping their bodies in the reddened river water.

Among the soldiers of the Fang La Army who were pursuing, there were suddenly explosions, bursting burning sounds, and terrible cries of pain.

Thousands of poisonous smoke fireballs, tribulus fireballs, and thunderbolt fireballs burned and exploded in a short period of time, directly enveloping the Jiangtan camp of the Great Zhou Army not long ago in a sea of fire!

The sound of heat waves, air waves and earth-shaking sounds woke up the Xunyang foot soldiers by the river and turned many people up. Unburned wooden spikes and strips of cloth fluttered in the air, revealing the immense power of gunpowder.

Yu Yunwen saw the tremendous power of the concentrated bombardment of firearms, and he suddenly had an idea: if he used more powerful thunderbolts and earth-shaking thunderbolts, if he used hundreds of three-bow bed crossbows to concentrate on projectile firearms, what kind of scene would it look like to destroy the world?

However, Yu Yunwen didn't have time to think about it, because he finally couldn't support it anymore and fell into a coma with a fever.

"Lord Yu, Lord Yu!"

The guards and several civil officials around Yu Yunwen shook Yu Yunwen lightly a few times, and when it was confirmed that Yu Yunwen was unconscious, he was shocked, and he wanted to shout loudly.

Zhang Tianlei stopped in time, frowned and reminded: "Even if Lord Yu is unconscious, he still holds on to the chair firmly, just for fear of affecting the morale of the army. Today's battle has an eyebrow, and the news of Lord Yu's illness should be blocked. ”

"Be careful to help Lord Yu into the cabin, and take care of the Hanlin medical officer, so as not to let the sergeants below see anything."

"Evacuate to the south bank first, it is important to keep the camp on the south bank, and other things will be decided after Lord Yu wakes up. What do you think? ”

The panicked civil officials still have any ideas, and it is all up to Zhang Tianlei to make the decision at the moment.

Zhang Tianlei discussed with the commander of the Xiangzhou Navy and decided to withdraw to the south bank first and hold the camp without leaving. After Lord Yu wakes up, or after receiving a clear order from the court, he will decide on his next move.

Yu Yunwen is in serious condition.

Zhang Tianlei handed over the beautiful mission that escorted Yu Yunwen to the south bank first, and left him near the north bank until he saw Xunyang's foot soldiers boarding the boat away from the river beach, and then sailed south.

When Zhang Tianlei was at the stern of the boat looking at the fire on the river beach, Fang La happened to be close to the riverside to boost morale. The two glanced at each other, but they were too far away to see each other clearly.

Fang La retracted his gaze at Zhang Tianlei's ship, frowned at the tragic scene caused by the concentrated explosion of the Great Zhou firearms, and gasped:

"The firearms of the Great Zhou Army are really beyond the reach of manpower."

"It's really earth-shattering, fortunately, the Great Zhou Army didn't concentrate on the use of firearms in the camp, otherwise I don't know how many of my 10,000 elites would be left?"

"My Yongle Dynasty's gunpowder workshop still can't produce usable gunpowder in large quantities?"

Gao Yu, the waiter, looked at the soldiers who were burned and injured, and replied with concern:

"Firearms such as the Great Zhou Dynasty military poison fireworks ball and tribulus terrestris fireball can already be produced in small quantities by the workshops in Hangzhou. However, due to the continuous accidents and storage difficulties, the daily production has not been able to rise. ”

"For a firearm as powerful as the Thunderbolt Fireball, the craftsmen have not yet found a good recipe, and the things they have made are far inferior to those of the Great Zhou. The Great Zhou Dynasty improved its gunpowder recipe for more than 100 years, and only produced the best gunpowder in three places, but Hangzhou City was not one of them. ”

"Fortunately, I found books like "Wujing General Essentials" and "Heavenly Creations" in the Yongle Dynasty, otherwise there would be no rice to cook."

Fang La nodded and accepted Gao Yu's words.

Not to mention not knowing the best recipe, even if you do, gunpowder is not a general commodity that can increase production in a short period of time. After killing many craftsmen, Fang La finally understood that there were some things that could not be forced.

The Great Zhou Dynasty accumulated for 200 years to have today's huge gunpowder production. Even so, the military gunpowder of the Great Zhou Dynasty was also cautious and careful, and accidents of all sizes occurred from time to time.

There was one thing that made Fang La very confused. Why did the scholars of the Great Zhou Dynasty write several formulas in books and print them all over the world?

The Liao State learned firearms, and the Western Xia also learned some, although it was far less than the Great Zhou, but it was always very troublesome. Fang La didn't know what the scholar of Da Zhou thought, but he didn't care much.

He Conglong inspected the tragic injuries caused by gunpowder on the bodies of some dead soldiers, and said worriedly: "If the Great Zhou army concentrates hundreds of bed crossbows and fires like rain, how should they respond? ”

Fang La shivered at first, then thought carefully for a while, and said:

"Don't worry too much, there's no such thing."

"The Great Zhou army concentrated dozens of warships, fired firearms at the shore, and blew up five of their own ships."

"It's still on the water, and the explosion of the ship won't affect the other ships, so what if it's marching on the ground?"

The large-scale use of firearms on land is far more difficult than on water.

Firearms such as poisonous smoke fireballs, tribulus fireballs, and thunderbolt fireballs, each of which is not small. The question is, how to do if the firearm belt affects the march, and the belt is not enough to throw it in one round?

The most powerful armament of the Great Zhou Dynasty, the three-bow bed crossbow, has a range of no more than two miles, and the firing of firearms is greatly discounted. If you want to use firearms to defeat the enemy, you must get close to the enemy, so you need a large number of soldiers who dare to fight hand-to-hand.

There are so many soldiers who dare to fight hand-to-hand, what battle can't be won, and they have to rely on firearms?

If you want to fire firearms in a concentrated manner, catapults, five-sentry cannons, and bed crossbows are indispensable. It takes a lot of people, it takes a lot of open space, and it's easy to cause a chain of explosions.

On the battlefield, how to ensure that all conditions are met? Behind him is a powder keg that explodes at any time, how many soldiers are not afraid, like puppets to cooperate with the firearms force to attack? Once the firearm is used up......

In short, the current use of firearms is severely restricted. Firearms are very useful in fortification, camp and water warfare, and should be used with great care in the field, as it is annoying to have too many restrictions.

If we want to concentrate on the use of firearms, it is necessary to think completely about the problems of battlefield supply, weather, terrain, troop coordination, soldier quality, ordnance, and so on, and comprehensively reform the military system. Unfortunately, with the current conditions of the times, many things belong to the Arabian Nights.

Li Xiang was too far ahead in some things, but he was fiercely rebounded by the reality of the situation, hurting others and himself.

If firearms were really so good, with the world's financial and technological resources of the Great Zhou, the Khitans would have been driven to Saibei to eat snow, the Dangxiang people to Mobei to graze sheep, and the Uighurs out of the Western Regions. Of course, the above is only an analysis from the perspective of weapons and national strength, if there is something wrong with the command, the soldiers dare not fight, and the court only cares about internal fighting, no matter how good the weapon is, it is useless.

Fang La is right, no army will send 10,000 troops who dare to fight, specially escorting thousands of firearms troops that may have accidents at any time, are extremely expensive, have harsh combat conditions, and become a burden when they run out of firearms, unless all the generals are dizzy.

Take the equipment army of Da Zhou as an example to illustrate the embarrassment of the "advanced troops".

The equipment army needs to carry a lot of baggage, which is very expensive, and the advantage is that it is easy to defend and use.

The disadvantage is that a lot of preparation work is required before the battle, a large amount of open space needs to be occupied, and other troops need heavy protection to kill and injure the enemy within a certain distance, and it is easy to injure one's own people, and it can only rest when it is windy and rainy. When you run out of rocks and firearms, you become waste, and once you lose the battle, you can't run fast.
