Sending Chen Sima away, Ma Chao couldn't help but ponder, now that Cao Ying has collected hundreds of thousands of Yellow Turban thieves, there is already a trend of getting bigger, if Liu Bei is allowed to take the opportunity to become bigger, it will be very bad. According to historical development, Tai Shici made his debut at this time, and moved the rescuer Liu Bei for Kong Rong, and Liu Bei met Xuzhou Mizhu because of this, which coincided with Cao Ying's attack on Xuzhou, and Lu Bu took advantage of the empty army to send Yanzhou, and the dust settled after several years of continuous melee.

If such a lively scene is not stirred, how can it be worthy of the identity of the traverser? Besides, it's time to clean up Gongsun Zhan, if the four states of Northern Merge, Hebei, Qing, and Youzhou can be won, plus the place of the division, the general trend of the world is almost a foregone conclusion! There are only five people left: Yuan Shao, Cao Ying, Sun Jian, Liu Biao, and Liu Yan, among which Cao Ying and Liu Biao are not worried, both of them are poor people, as long as they are not given a chance to breathe, it is not difficult to extinguish. Han Sui sent troops to help in Shu, if Xu Shu could plot against the Nanban, and then send a large army to attack Hanzhong, Liu Yan would be disabled if he did not die. Only Yuan Shao and Sun Jian have some hot hands, one has the identity of the fourth and third princes, which is quite popular with the local people, and the other has the Yangtze River to defend, which is deeply rooted in the local area.

Having made up his mind, Ma Chao summoned all his confidants, generals and strategists to the General's Mansion to discuss together. During the banquet, Ma Chao got up and said: "Ladies and gentlemen, it coincides with the wedding of this general, and it is rare for you to hand over military affairs to the deputy general before you can gather together!" If there is a big chaos today, the princes of various places have broken away from the court and divided one side, and they are really not subordinate! I would like to raise an army to fight for it, but I can't make up my mind for a while, so I would like to take this opportunity to ask you to express your views on the current situation today."

Everyone such as Tian Feng, Fu Zhu, Xian Pei, Xun You, Fa Zheng and other strategists, as well as Zhao Yun, Huang Zhong, Dian Wei, Zhang Liao, Zhang He, Le Jin and other military generals, as well as Chen Qun, Zhong Xuan, Zhang Zhao, Wei Kai, Zhuge Xuan, Zhang Ji, Qin Yi and other officials promoted by Ma Chao are all in place, which can be said to be gathered together.

When they heard this, they were all silent, and not one of them was willing to take the lead.

Seeing this, Ma Chao said: "Yuan Haojiu has been in Guanzhong for a long time, and he knows Shu best, and he wants to send troops to attack Shu, is it feasible?" ”

Tian Feng hugged his fists and said: "Liu Yan claims to be the emperor in vain, the lord is the regent, and he has the responsibility to maintain the majesty of the imperial court, and the battle of Shu is imperative!" However, at this time, Guanzhong's vitality has not recovered, and I am afraid that it will not be able to provide too many military supplies. ”

Ma Chao asked: "Judging from the current grain stockpile, how many troops can be raised in Guanzhong at most!" ”

Tian Feng pondered for a while, and said confidently: "In addition to the expenses of the defenders, it can also support the supply of grain and grass for 50,000 people a year!" ”

Ma Chao nodded, and said with a straight face: "The general has other important matters, I'm afraid I can't lead the army in person, I don't know which of the generals is willing to lead the heavy task of cutting down Shu!" ”

"The last general is going to fight!"

"The last general is also invited to fight!"

Pang De was the first to stand up and ask for battle, and then Huang Zhong, Zhao Yun, Le Jin, Zhang Liao and others asked for battle, this is a single leader to fight, an excellent opportunity to become famous, and the generals will go all out to fight for it.

Seeing that the generals were scrambling, Ma Chao couldn't help but be overjoyed, and said with a smile: "With all the heroes to help, why worry about the big things?" However, the land of the Central Plains is the most important thing, and the general will appoint a few fierce generals to go out today, and the rest do not have to be discouraged, and there will be countless opportunities to make contributions in the future! ”

"Please order the general!"

Ma Chao nodded, and said with a straight face: "Pang De, Fa Zheng, Ma Dai, Le Jin, Wang Shuang, Wu Kuang, and Zhang Zhang listen to the order!" ”

"Mo will be!" The seven people who were named hurriedly stood up and bowed down on one knee!

Ma Chao said: "Ming'er and other leaders of the headquarters of the people, with Pang De as the main general, Le Jin, Wang Shuang as the deputy general, Ma Dai as the army, Fa Zheng and Xu Shu as the military division, wave the army of 50,000 out of the Dasan Pass to attack Hanzhong Zhang Lu, be sure to capture Hanzhong within a year, with Hanzhong and Guanzhong as the base, it is easy to destroy Liu Yan!" ”

"The last general commands!"

Ma Chao said again: "The general's father-in-law, Liangzhou Mu Han, is also going to send troops into Shu, and the Xiao Pass guarded by General Wang Shuang only leaves 5,000 soldiers and horses to guard it!" The same is true of Wen Qian's Great Dispersal Pass! In addition, if you meet the generals Zhang Ren, Yan Yan, Gan Ning, and Wu Yi, the nephew of General Wu Kuang, you must be extremely careful, the four of them are not idle people! Don't be careless! ”

Everyone was surprised, Ma Chao had never been to Shuzhong, how could he know so much about the generals in Shuzhong. I only heard Ma Chao say again: "There are many mountainous areas in Shuzhong, full of mountains and rocks, which is not conducive to the impact of cavalry, but it is conducive to the use of Xiangyang cannons, and the drawings of Xiangyang cannons will be handed over to Fazheng, and you will first train troops in Guanzhong for three months, and at the same time recruit craftsmen to make a large number of Xiangyang cannons, train artillerymen, and then send troops in April!" ”

Several people hurriedly received the order. Ma Chao said again: "Yuan Hao is still in Chang'an, responsible for governing the local and logistics supplies, and he could have arranged Ma Tie and the surname Cao in Chang'an to listen to your dispatch!" ”

Tian Feng hugged his fists and said: "The lord is fully prepared, he has no last resort, he will be able to fight a battle, Tian Fengyan dares not to do his best!" ”

Ma Chao shook his head and said: "Things are man-made, there is no absolute thing in the world, in order to reduce the casualties of our subordinates, we can only try to think about the possible surnames of each step, so that we can win more and lose less!" After that, he clapped his hands and said: "On the occasion of the general's wedding, there is also a small return gift for the generals here!" ”

As soon as he finished speaking, two soldiers carried in a large wooden box with a heavy weight, and when he opened it, he saw that it was a wooden cone. Most of the people didn't know about it, but how could people who had been in Yecheng for a long time, such as Matthew, Frustration, and Judge, not know it, and exclaimed: "Could it be clairvoyance!" ”

Ma Chao said with a smile: "It is the 'clairvoyance', also known as the telescope, which can be used to observe in an open place, which is enough to see things twenty miles away, which is very useful for marching and fighting." However, this thing is quite troublesome to make, and it is necessary to polish a large piece of crystal into a concave and convex shape, which is extremely fine, which will make the craftsman rush to work all night to make dozens of pairs! Today, the generals and military advisors present can receive a pair! Wang'er and the others can take care of it, and it is better to destroy it than to fall into the hands of the enemy! ”

Everyone claimed that it was, but they were extremely curious in their hearts, and when they got their hands on it, they were all surprised, and sighed that Ma Chao was a genius in the world.

Ma Chao was secretly proud in his heart, the telescope was just an insignificant gadget, and he was thinking about how to configure black powder these days. Black powder can only be used as a propellant for primitive artillery, and it is slightly insufficient to blow up city gates and walls.

However, according to historical records, nitric acid and sulfuric acid are the products of the failure of alchemy in ancient China, among which nitric acid can be obtained by dry distillation of saltpeter, and saltpeter is not a rare thing, so it can be experimented. Sulfuric acid can be obtained by dry distillation of stone gall, also known as bile alum, which is also a mineral with a wide range of parts.

As long as a certain concentration of nitric acid and sulfuric acid is made, it can be prepared into nitroglycerin, a high explosive, and matches can be studied no matter how bad it is. In fact, a lot of nitride can be used as explosives after processing, but in this era, there is no way to make a detonator to detonate, so even if you put it in a fire, it will not explode. But nitroglycerin is different, this thing is liquid before adding stabilizers to make sticky explosives, and it can be detonated by violent collision or a few sparks, and the power is amazing, far exceeding that of TNT explosives in later generations.

Although Ma Chao knew the method of making nitroglycerin with concentrated nitric acid and concentrated sulfuric acid, he didn't dare to try it easily, that thing was too dangerous, and if he didn't get it right, he would blow himself up, and the conditions in this era were too poor, and the risk factor was even higher. But if it could, it would be better to get a group of slaves and death row prisoners to carry out this experiment, and once it was successfully developed, where could the world go?
