Zhang Xiu immediately made arrangements for the people who can control the flying ball to return to the barracks with the flying ball and Zhang Xiu. The rest of them stayed in the mountains for the time being. When Zhang Xiu went north, he took all of them with him.

This time, Hu Mo was the first one to return to the army with Zhang Xiu, and there were 95 others, totally 96. Because in each basket, there are two people working together.

Back at the camp, Zhang Xiu arranged for people to send a batch of money, food and meat to the place where the Mohist children gathered, and then arranged for Hu Mo and other 96 people separately.

After all this, the army continued to set out.

At night, it's dark.

When the army stops, Zhang Xiu calls Pang Tong and Sima Yi together again to discuss the use of the flying ball.

Although Sima Yi knew that there were flying kites in the ancient books, he still had a certain skepticism about the flying ball. He said in a deep voice: "Lord, it's not easy to say that he was humble in the Mohist residence before. But is this flying ball OK? "

"You can do it!"

Zhang Xiuding replied.

Sima Yi said, "after all, I haven't tried!"

Zhang Xiu said: "when you arrive at baishuiguan, you will know. But now, we have to consider how to use the flying ball to attack baishuiguan. I don't think much of the use of flying balls to transport soldiers into the pass. Because there is Zhang Ren's army in baishuiguan. With Zhang Ren's army here, a few of our soldiers may not be able to win. "

"It is!"

Pang Tong nodded with approval.

After thinking about it for a while, he said, "in fact, there is a proposal for humble position."

Zhang xiudao: "what suggestion?"

Pang Tong replied: "use these 43 flying balls to drop cupping pots into the pass. Put the fire oil into pottery pots one by one, seal them and then block them with hay soaked in fire oil. After lighting them, throw them from high in the air and throw them into Zhang Ren's camp. "

"To determine Zhang Ren's camp, we can choose to operate at night."

"At night, it's not just baishuiguan that lights the torch. Besides, there must be torches burning in Zhang Ren's camp. In this way, it is very easy to determine the location. "

"There are countless tents in the camp."

"After the cupping pot was thrown down, the fire oil diffused. Once ignited, the entire camp will turn into a sea of fire. At that time, Zhang Ren's army can withdraw, but it will also be in chaos. "

Pang Tong said: "take this opportunity to attack baishuiguan immediately. Without Zhang Ren, who had been rescued by the army, he would not be able to defend baishuiguan, and he would surely be defeated. "

"Wonderful, really wonderful!"

Zhang Xiu's face was full of smile. He agreed with Pang Tong's suggestion.

In this way, even if Zhang Ren was stationed at baishuiguan, his army would not be able to defend even if it was damaged.

Sima Yi said: "Hu Mo has said that in order to fly, we must consider the wind direction. Otherwise, once the flying ball takes off, the direction of flying may not be our white water pass, but to our rear, or to the other direction. In a word, we need to find out the wind direction before we can take action. "

For the flying ball, although Sima Yi has a skeptical attitude, but now, he can only believe it.

In the present situation, there is no choice.

Zhang Ren is not a coward.

It is not easy to defeat Zhang Ren with his strength. So we have to make a surprise attack by flying ball.

After setting the strategy of sending troops, Zhang Xiu looks forward to it.

The army went straight south.

Baishuiguan, located in the northernmost of Guanghan County, is not only the northernmost barrier of Guanghan County, but also the barrier of northern Sichuan. Although Baishui pass is not as dangerous as xiegu pass and Jianmen pass, it is the gateway of Liu Zhang.

When Zhang Xiu and Zhang Lu were at war in Hanzhong, Liu Zhang transferred Yizhou General Zhang Ren to baishuiguan to defend against Zhang Xiu's army which might invade south.

On the tower, in a sunny room.

Zhang Ren, the chief General of baishuiguan, is in charge of military affairs.

He led the troops and garrisoned at baishuiguan. Under his command, there were 30000 excellent troops and strong troops. In particular, with the help of baishuiguan, Zhang Xiu's main road to the south is occupied by geographical advantage.

"Newspaper!"

All of a sudden, a thick voice sounded from outside the room.

Zhang Ren put down his pen and said, "come in!"

The door crunched open and a middle-aged scholar entered.

Gu can is Zhang Ren's aide. When he saw Zhang Ren, he held his fist and saluted, "general, I have the latest war report. Zhang Xiu's army has entered the territory of Baishui County and is going to kill in the direction of baishuiguan. "

"I see!"

Zhang Ren nodded and answered.

Finally, his eyes flashed.

After Gu can stood still, he looked like he wanted to talk and stop.

Zhang Ren said: "what do you want to say, but it's OK to say it?"

Gu can said in a deep voice: "general, we have followed you for a long time. We know that you and Zhang Xiu are brothers. If Zhang Xiu spreads the news after he arrives at baishuiguan, I'm afraid it will be bad for you. Isn't the general going to report this to the governor? If the news spreads in Chengdu, I'm afraid it's not good for you. "Zhang Ren waved his hand and confidently said, "it's a small matter, it's not enough to be afraid. You can rest assured that I have a plan to deal with it. "

"The general is wise!"

When Gu can heard Zhang Ren say that he had a strategy, he was also steadfast in his heart and turned around to retreat.

Zhang Ren continued to sit in his study, dealing with military affairs. After all the military affairs are handled properly, Zhang Ren gets up and leaves the room to go to the barracks in baishuiguan.

Camp in the army, soldiers are training.

Zhang Ren led the army to fight, and all his officers and men trusted him.

It's not only Zhang Ren's excellent martial arts, but also because Zhang Ren doesn't do anything special. He eats and lives with his soldiers. A person who is good at martial arts, knows how to March and fight, and can fight with soldiers is not a weak one.

Now it's near June and it's hot.

This place in Sichuan is even more stuffy. Before June, soldiers were sweating when they practiced. However, the soldiers under Zhang Ren's command, originally Yizhou native, are used to such weather and don't find it difficult.

Zhang Ren personally led the soldiers to practice, which helped to boost the morale of the soldiers in the army.

In this way, time passes day by day.

Just after June, when the weather was getting hotter and hotter, Zhang renzheng was training soldiers. Gu can came to Zhang Wei in a hurry and reported: "general, Zhang Xiu is less than ten miles away from baishuiguan."

"Here we are at last!"

Zhang Ren stopped, told the soldiers to continue the training, and transferred another 3000 soldiers to the tower quickly. He came to the tower, wiped his sweat, changed his clothes, and stood on the tower waiting quietly.

Time goes by little.

Zhang Ren's face was full of anxiety.

As a general at the border, Zhang Ren has enough patience to wait for the arrival of Zhang Xiu.

"Boom!"

Suddenly, to the north of baishuiguan, the sound of horse's hooves sounded. Trampling on the ground, the whole baishuiguan inside and outside, began to shake up, as if there was a tsunami, surging to baishuiguan.

A moment later, Zhang Ren saw a black line in the distance.

This black line is creeping fast.
