Both Zhang Hong and Guo Jia agreed with Xun's suggestion, but with different emphasis.

The reason for Zhang Hong's approval was that although Zhou Yu had experience in commanding 10,000 people, he had always been mainly defending the city before and had not experienced major battles. This time is different, he has to fight with Liu Xun, Chen Ji and others, and may also organize a siege, and his subordinates have to lead generals like Deng Zhan and Lou Gui, as well as Sun Fu, with Zhou Yu's qualifications, I am afraid it will be difficult to convince the public. If Sun Ce went out together, he could coordinate the generals more conveniently than Zhou Yu and reduce internal friction.

No matter when, internal friction will always exist, and the difference is only whether the main general can control it well and not let internal friction affect the overall situation. Zhou Yu has outstanding ability and will definitely be a general in the future, but he is still young now, and he has no good record, so it is difficult to convince people.

The reason for Guo Jia's favor is from a tactical perspective. Although ordinary people like to see that less wins more, and the weak defeat the strong, from the perspective of the art of war, especially when the temple calculates, they still advocate concentrating superior forces to bully the weak in order to overcome them. In addition to supporting Xun You's suggestion, Guo Jia further proposed a tactical plan that combines virtual and real. With Zhou Yu as a hypocrisy, he marched to Nanjun with great confidence, and took Sun Ce as a reality, led the elite and light army to break into Jiangxia. If Liu Xun goes to save Nanjun, Sun Ce can take Jiangxia lightly. If Liu Xun is not saved when he sees death, then Sun Ce will control Xiling, contain Liu Xun, and let Zhou Yu face Chen Ji, which can also form an advantage in military strength.

Sun Ce felt reasonable, but the change of the battle plan was not something that could be solved in one or two sentences, and there was at least one problem to be solved.

"What about Lujiang?"

Guo Jia shook the feather fan and said unhurriedly: "The way of using soldiers is real, and the truth is real." When we change our battle plan, we are not giving up on the Lujiang River, and at the same time as the elite breaks through into Jiangxia, we can make a posture of attacking the Lujiang River. If Chen Deng is based on the city, then we will take Jiangxia and then wave eastward. If Chen Deng leads an army to attack, we will introduce him into the territory of Runan and see who will welcome him. ”

Sun Ce nodded again and again. Even if he goes on the expedition, Runan still has his father Sun Jian in charge, and there should be no problem in settling Chen Deng. If Chen Deng enters the country, the Runan family will definitely respond, and when they jump out, they will be justified if they are cleaned up.

This trick lures the snake out of the hole, and it is perfectly combined with his knocking on the mountain and shaking the tiger, saluting first and then soldiering.

"Then ask the two of you to reformulate the plan, and then discuss it with Gongjin and Gongda." Sun Ce thought for a while, and then said, "It's best for you to go to Nanyang in person." ”

Guo Jia smiled. "I thought so too, but I didn't have time to say anything yet."

——

Early the next morning, Guo Jia left Gebei, and Sun Ce arranged for Chen Zhi to lead Bai Yushi to escort Guo Jia to Nanyang, and before that, let him go back to Pingyu to meet his family. Guo Jia has already married a family, a wife and a concubine in the family, and his wife gave birth to a son named Guo Yi, who is only more than three years old. Guo Jia always looked proud when he mentioned this son.

Seeing off Guo Jia, Sun Ce and Zhang Hong boarded the ship and came to Ge Pizhong to watch Huang Yueying's new ship sea trial.

This is a medium-sized warship about ten zhang long, often called a fighting ship. In the Han Dynasty, there were building ships, but the building ships were large in size, slow in action, looked majestic, but unstable, and were very easy to capsize in the wind. It was the warships or the fighting ships and Meng Chong who really went into battle. Meng Chong is small in size, moves quickly, can quickly break into the enemy formation, and perform assault tasks, but the load is small, the number of fighters is limited, the main battleship is still a fighting ship, can rush or collide, and crossbowmen can also be arranged on board.

Huang Yueying's warship was not new, but was converted from an old ship. Compared with the previous old ship, this ship has a deeper draft, but the number of oars has been increased, and the speed has not been affected, but it is faster, and the biggest feature is that Huang Yueying has installed a stone thrower on it. The stone thrower is not big, and it uses iron pellets instead, with a range of up to two hundred paces, ten rounds can reach three or four hits, and within a hundred steps, it is enough to knock a wooden boat out of a hole, and Sun Ce saw with his own eyes that a target ship was broken down and slowly sank into the water.

"In the event of a war, you can also replace the iron pellets with clay pots filled with oil, and then use them with rockets to burn the opponent's warship." Huang Yueying was very proud, her eyes lit up, and her hands danced. "However, the real killer of this ship is not the catapult and the crossbow, but the ramming. Just rush over it, and with a single collision, you can knock the opponent's boat out of a big hole. Huang Yueying opened her arms and made a very exaggerated posture, holding her clothes tight, and the bud showed a faint shape, but she didn't realize it.

"You reinforced?" Sun Ce looked away and looked at the warship in the distance.

"Well, I used an iron keel."

Sun Ce was taken aback. The iron keel is indeed not afraid of collision, but it is afraid of rust. "Isn't the iron keel not afraid of rust?"

"There's lacquer, what are you afraid of? However, it must be overhauled after every war, otherwise the paint will be touched off, and it may indeed rust. Huang Yueying scratched her head, a little embarrassed. I wanted to use copper, but it was too expensive. ”

Sun Ce laughed. "It's rare that you still know how to save, it's not easy. However, have you ever thought that although iron pills are easier to form than stones, after all, they are one-time consumables, and how many iron pellets will you get after a battle? ”

"It's a problem, so it's important to improve the hit rate."

"When the two armies are fighting, it is no longer easy to maintain such a hit rate, and there is no possibility of greater improvement in the short term. However, there are other ways to save iron shots, such as tying a rope to them. ”

"Shooting?"

Sun Ce thought about it and felt that this analogy was indeed very appropriate, but it was not the result he wanted. He followed the temptation and continued: "Yes, it's a bit like a shot, but I think it's more like a meteor, have you ever seen a fire meteor?" ”

Huang Yueying opened her mouth wide and nodded slowly, a smile blooming from the corner of her eyes. She clenched her little fists. "That's right, in this way, melee combat can also play a role, such a big iron pellet smashes down, hehe, no matter what ship he has, he wants to look good." She patted Sun Ce hard, blinked her eyes, and smiled with a red face: "I knew you had a better idea, and it didn't disappoint me." ”

Sun Ce turned his head to look around. "Why didn't you see Xu Gonghe? This large meteor hammer can be a bit complicated, so it's best to let him calculate it along to see how to optimize it and avoid detours. ”

"He's almost stunned, and I'm going to test the landing time alone. He said that your idea is very good, it is easier to solve the problem by breaking down an arc into two straight lines, and as long as the time problem is solved, he may be able to write the formula. ”

Sun Ce was not happy at all. This idea is good, and the direction is not wrong, but it is not feasible. To calculate the formula for free fall, you must first have a sophisticated timekeeping tool, and a leaky pot is definitely not a no, at least accurate to the second. Using a colander to measure free fall time and Galileo Galilei measuring the speed of light with a kerosene lamp is just as unreliable.

You won't really drive this big-money mathematician crazy, right? Then I'll lose a lot.
