The Elder Jin in Chu Yun's mouth is the head of the three tones of the Demon Sect, and he is known as Yu Zhu of Jin Xiao Langjun.

The three tones of the Demon Sect are the white-haired magic flute Shen Xi, known as Elder Bai, the purple-clothed qin girl Chu Yun, known as Elder Zi, and Jin Xiaolang Jun Yu Zhu, known as Elder Jin. The three of them all use musical instruments as weapons, and their stunts are all true qi sounds, killing people invisibly, so they are called "Demon Sect Three Tones". The prestige of the three tones is like thunder in the rivers and lakes, and no one knows it, and no one knows it.

However, above the three tones of the Demon Sect, there are two major protectors on the left and right, which is the existence of Wulin Tan.

Chu Yun's meaning was that after Yu Zhu arrived in Lanzhou, he would cross the city of Lanzhou with her and Zhao Wuxian, destroy the artillery of the Ming army and create chaos, and cover the army to cross the river.

With the cultivation of three people, it can indeed be done.

As long as the firearms and archers at the head of Lanzhou City are dumb, I believe that the Demon Sect can relieve at least half of the pressure, and the army will cross the river and successfully capture Lanzhou City.

Zhao Wuxian thought about it and felt that Chu Yun's opinion was feasible.

As long as he can capture Lanzhou City, what if he, the left protector, will personally take action?

Although Zhao Wuxian was the second person in the Demon Sect and his martial arts were also at the peak, he always regarded himself as Yan Wuyue's slave. He is an avid follower of Yan Wuyue, and even if he gives his life for him, there is nothing to say. This is very different from the right protector Mei Yinzhi, who has always been cold and vague and erratic. Therefore, in the left and right protectors of the Demon Sect, there has always been a saying that the left is hot and the right is cold.

Zhao Wuxian said, "What Elder Zi said is also a plan, and it can be discussed in detail after Elder Jin arrives. Then, he looked at Chen Hou, the master of the Houtu Banner, and said, "Master Chen, you have also seen this siege, my disciples suffered heavy losses when crossing the river, do you have a good plan?"

Chen Hou still looked listless, and his eyelids were only halfway raised.

He had to answer Zuo Protector's question, so he had to say, "Let your subordinates think about it, and then go back and tell the Dharma Protector." ”

Zhao Wuxian's face turned dark, and he said coldly, "Master Chen, now that the army has been released, and countless brothers die on the battlefield every day, is it the time to be vindictive? Whether you want to or not, sending troops is the order of the sect leader himself, since it is the order of the sect leader, we should swear to the death, how can you be so slack? Could it be that you want to be like Shen Xi?"

At the mention of Shen Xi, the faces of everyone present changed slightly.

An eerie vibe spreads.

On that moonlit night two months ago, the events of the Bright Dome resurfaced in everyone's minds—even though none of them wanted to remember them.

Chen Hou said expressionlessly, "The subordinates don't dare." ”

"You say, is there a way for your Houtu Banner to help the brothers cross the river!" Zhao Wuxian asked in a questioning tone.

Chen Hou sighed and said, "If the brothers can't cross the river, then cross the bottom of the river." The subordinates asked the brothers to dig two paths at the bottom of the river, and they went straight to the city. ”

Zhao Wuxian's face looked a little better, and he asked again, "How long will it take?"

"Fifteen hundred brothers in Houtu Banner will start work day and night, and it will be completed in about two days. However, it also depends on whether the Ming soldiers on the opposite side will find out. ”

If the Ming army found out that they were digging a passage, they could easily destroy the tunnel by simply digging a hole in the ground, filling it with water, or throwing a bunch of thunderbolts.

Zhao Wuxian waved his hand, "It's okay, you just need to start construction immediately! Before tomorrow night, be sure to dig out these two fellow Daoists!"

Chen Hou received the order, and then left the camp without saying a word.

That day, the Demon Cult did not attack.

In the city of Lanzhou, Cao Wenzhao, the chief soldier of Gansu, Wang Gulun, the governor of Gansu, He Kegang, the commander of the Guanning army this time, Hei Yunlong (a favorite general of Mangui's confidant) who led the Datong soldiers, and You Shigong (the younger brother of You Shilu, the general soldier of Xuanfu) and other generals gathered together to discuss the strategy of retreating from the enemy.

The main topic of discussion for everyone was how to fight if the Demon Sect continued to attack the city tonight.

Most of the generals suggested that they should defend the city tonight, and should not send troops to directly engage the Demon Cult under the city. Lanzhou City has a moat, and the officers and soldiers can use cannons, arrows, and muskets to consume them when the Demon Sect crosses the river, and after they are concentrated in the city, they can kill them with fire oil, asphalt, boiling oil, etc.

This proposal sounded very good, but Cao Wenzhao was worried that once the Demon Sect crossed the river, the collapsed South Gate would become a breakthrough for them. If the Demon Cult broke into the city, the consequences would be unimaginable.

Although the south gate is being restored, there is a large amount of ruins there, and it cannot be cleaned up in a short period of time, so it cannot be rebuilt. At present, the so-called "restoration" can only be to pile up the ruins and pour them with clay mixed with glutinous rice to improve the firmness. In addition, a large number of migrant workers built a wall out of rammed earth on the perimeter of the ruins. The rammed earth wall is naturally not as strong as the city wall, and can only resist the opponent slightly for a while.

Despite this, the collapsed south gate is always the weakest point in Lanzhou City. The Demon Sect only needs to tear down the earthen wall, and then step on the ruins to cross the south gate, and it can't even use the siege ladder, how can Cao Wenzhao rest assured?

"General He, what is your good plan?" Cao Wenzhao asked He Kegang. Here, He Kegang is a relatively famous general and is very respected, so Cao Wenzhao wanted to ask him what he meant.

He Kegang said, "The general thinks that the Demon Sect will not take the offensive like last night tonight. ”

Cao Wenzhao asked with some surprise, "Why?"

"Lanzhou City is so important to Gansu, the Demon Sect knows that the army of Qin Shaobao and Governor Hong will arrive soon, and it is bound to capture Lanzhou before they arrive. The Demon Sect claims to have an army of 300,000, but the soldiers who attacked Lanzhou this time were only 90,000, of which 30,000 were still Ma Shouying's thief army. So Ben thought that they didn't have that many soldiers at all. If they don't have enough troops, they are naturally afraid of attrition, and they can't afford to fight with such a method of attrition as last night. ”

Cao Wenzhao bowed his head slightly after hearing this, and said, "General He is reasonable. So what will the general think, what will they do?"

He Kegang said, "If we don't fight attrition, they may blow up a few more city gates at any cost, and then rush up to fight with us." They can't afford to drag it out. ”

"Do they have so much gunpowder?" Cao Wenzhao questioned.

He Kegang said, "The Demon Cult has always acted unexpectedly, they have a Flame Banner, which is said to be tyrannical gunpowder. So we had to guard against it. ”

The generals nodded their heads in approval.

Cao Wenzhao said, "General He is right, let's eat a trench and grow wise, and we must prevent them from digging tunnels again." Then he immediately shouted outside, "Someone." ”

A personal guard immediately came in, "What does General Cao command?"

"Tell me to go down and collect some vats. Knock off the bottom and bury it in the ground, leaving only the mouth of the cylinder on the top, and then send someone to listen for any abnormal movement underground. By the way, find more buried near the city wall and listen day and night. ”

The guards immediately responded, "Obey!"

He Kegang thinks that the Demon Sect may dig tunnels and then blow up the city gates, but in fact, the Demon Sect only wants to dig tunnels to transport troops, but it can be regarded as a crooked fight.

The fighting methods of the two sides have just begun.

At this time, Qin Shuhuai took seven masters, and he had already rushed to nine hundred miles away.

Under the calm appearance, Lanzhou City is destined to usher in a storm that will go down in history.
