Three days later, Zhang Nan led 100000 troops directly into Yunzhou, from confrontation with Cai Yun's two armies to the offensive stage.

But Cai yunkong had more than 100000 troops, but he fled all the way.

"Marshal, we are more than 100000 troops, more than Zhang Nan's. why should we withdraw and lose?" In Dayao County, Yang Guang looks at Cai Yun in bewilderment, with a helpless face.

"General Cai, although there are many of us, do you see that Zhang Nan's men are good at fighting? We have two battles in succession, and we are all defeated by him. If our army doesn't withdraw, we will still confront him there. Once we lose, there will be no time to rise again. So my commander ordered us to withdraw, waiting for time to change." Cai Yun said.

"But when we withdraw, the door of Yunzhou is open. This gives Zhang Nan a chance." Yang Guang said.

"Although Zhang Nan's entry into Yunzhou seems overwhelming, he is not familiar with it. There are many miasma and poisons everywhere. When Zhang Nan enters Yunzhou, he is looking for his own death. Whether he can safely reach Dayao is still one thing." Cai Yun said triumphantly.

"Ah, marshal, we can't underestimate Zhang Nan. Do you know that when he was king Qin, he recruited 100000 people to go north, but when he came back, there were 300000 people in the army, which shows that Zhang Nan has a good way to tame his subordinates and win people's hearts."

"If you look at him, it took him less than two months to lead his troops into Sichuan and Sichuan, and he even occupied the whole Sichuan and Sichuan territory. I'm afraid he can't find a second one. I heard that after he captured Chengdu, he used Sichuan and Sichuan officials wantonly and reorganized the original Sichuan and Sichuan army. Now he supports no less than half a million troops, and now he only takes them If we miss such a good opportunity, we will be doomed. " Yang Guang said.

"Marshal, General Yang's words are reasonable. There are many powerful generals under Zhang Nan's command. If we can't take this opportunity to defeat him, it will be our Yunzhou army that will suffer losses." Xie Hai also immediately persuaded.

"In the general's opinion, what should I do now? All the troops have retreated into Dayao, so it's impossible to lead the troops out of the city again? " Cai Yun said.

"I don't know if Marshal ever remembered Shao Tong and Zhu Wantong?" Xie Hai said.

"Wantong? Naturally, I remember that this man occupied Shao Tong's land and had an elephant soldier in his hand. He supported tens of thousands of soldiers. My commander wanted to persuade him to surrender, but he supported his soldiers with self-respect, and my commander was afraid of his elephant soldiers, so he never enlisted him. " Cai Yun said.

"Now Zhang Nan leads his troops into Yunzhou. If Yunzhou falls and our army is defeated, Wantong will also suffer a great disaster. This is the truth that Wantong will not forget. The commander can write a letter to Wantong, promise him money and food, and invite him to send troops to help. He will certainly lead his troops to help. As long as Wantong is an elephant soldier, we will defeat Zhang Nan No problem Xie Hai said.

"Yes, Wantong is an invincible army. As long as his elephant soldiers help, Zhang Nan will be defeated." Cai Yun immediately wrote to Wantong, promising him 100000 yuan of grain and 50000 liang of silver, inviting him to send troops to refuse Zhang Nan.

After Zhang Nan entered Yunzhou, the army marched all the way to Dayao. However, there were many miasma and poisonous insects in Yunzhou. The army could only March about 30 miles every day. Moreover, many soldiers were poisoned because they were not acclimatized to the environment, and some were bitten by poisonous insects, which hindered the advance of the army.

"Marshal, it's only two days since our army entered Yunzhou, and thousands of brothers have fallen ill, and others have diarrhea all day, delaying the March. What can we do?" Li Jun comes to Zhang Nan and reports on the general's situation.

"Marshal, if it goes on like this, our army will not be able to resist the attack of Cai Yun. We have to find a way to control the diseases brought by the miasma and the poisonous insects. We don't know why. It's all over the ground. If it goes on like this, the three armies will suffer, and our army will be defeated." Jun Shen He Qiang said.

"Lord he, you are a native of Sichuan, and you are familiar with Yunzhou. How can you restrain yourself?" Zhang Nan Jinzhou asked.

"Marshal, you are asking the wrong person. Sichuan, Sichuan and Yunzhou are thousands of miles apart. There is a huge difference in local customs. It's useless to ask me. But general Wu Qiang is a native of Yunzhou. He must have a way." He Qiang said.

"Alas, how can I forget this matter? I'm confused. When I enter Yunzhou, I should let general Wu lead the way, but let him see the escorted grain and grass. I'm afraid he doesn't know that our former soldiers are suffering." Zhang Nan suddenly realized, and immediately summoned the Scouts: "you quickly go back to inform general Wu Qiang of the strange things that happened to the former army, and make him come to see me as soon as possible."

"Marshal, you don't have to blame yourself. Escorting grain and grass is an important task of the three armed forces. As a native of Yunzhou, general Wu is most familiar with the local conditions and customs of Yunzhou. It's safe to have him escorting grain and grass, but I didn't expect that the weather in Yunzhou is so different from that in Sichuan and Sichuan, and there are so many miasma and poisonous insects. It's not your fault." He Qiang comforts Zhang Nan.

"Alas, when this happens, we can only wait for general Wu to come and see if there is any way to do it. When the order goes on, the army will stop advancing and find a dry plain to camp." Zhang nanwunai shook his head and simply did not leave.At night, Wu Qiangcai came with people. Seeing that many soldiers fell ill because of taking too much miasma, and many others were bitten by poisonous insects, Wu Qiangcai immediately said to Zhang Nan, "marshal, why can the soldiers in Yunzhou control miasma and avoid being bitten by poisonous insects is actually relying on a kind of herbal medicine."

"This herb is called poison expelling herb. As long as people eat a leaf, the miasma will be sent out of the body slowly, and the poisonous insects around them will stay away because of the smell of the herb. People in Yunzhou will eat such a poison expelling herb from the day they were born. After that, the army will hardly be people in Yunzhou, so they will suffer from this disaster and will be the last general In a daze, I didn't remind the marshal in advance. "

After listening to Wu Qiang's words, Zhang Nan breathed a sigh of relief. Now that he had a way to restrain himself, it was the best. He immediately asked, "you can ask someone to look for this medicine as soon as possible."

"I've ordered people to collect this herb along the way. The herb can be delivered in two days. However, during this time, the officers and soldiers are afraid to insist more and the army should be strict in defense to prevent Cai Yun from sneaking attack." Wu Qiang said.
