The city walls of Muling Pass are solid, easy to defend but difficult to attack, and there is already a danger of "one man should be the pass, ten thousand men cannot open it".

At that time, Qi State was still not enough, and built a second Great Wall defense line ten miles north of Muling Pass.

The second line of defense goes north from the neck leg on the east side of Taiboding, passes through Caoshanting, Taiping Mountain, Qingshi Hutong, Chengding Mountain, Zhaiyue Mountain, Woniucheng, and turns a big turn in Linqu and Anqiu. In Ju County, the border of Yishui meets the first Great Wall. The two Great Walls form a "Great Wall City" with Muling Pass as the core radius of 50 miles.

The pass of the Second Great Wall is called "Daguan", and not far north of the Daguan is "Xiaoguan". Xiaoguan, Daguan, Mulingguan, and the three defense lines of three passes form a complete set of deep defense system.

Li Quan's more than 30,000 troops were defending Muling Pass, and his generals Zheng Yande, Yu Yang's brothers, Liu Qingfu and others led their troops to guard the three passes.

After Anqiu fell, Guoan led the remaining soldiers to meet. Li Quan expected that the Jin soldiers might plagiarize and encircle Muling Pass from the south and east.

He felt the situation was serious, and while ordering all departments to strengthen defense, he discussed with the generals and made emergency arrangements. Once Muling Pass was out of protection, he would break westward and enter the Yimeng Mountains.

Li Quan didn't know much about the Red Turban Army and was also afraid of being vigilant. Although he accepted the stone throwing machine and expressed his gratitude, he never dared to let the Red Turban Army enter the pass and assist in defense.

When the Red Turban Army sent another letter to inform the Jin army that the South Road had plagiarized had been defeated and wanted to attack Wanyan Eren with Li Quan, Li Quan and his generals were shocked, and it was unbelievable.

In the hall of Guanlou, Li Quan, Li Fu, Liu Qingfu, Guoanyong, Zheng Yande, Tian Si, Yu Yang, Yu Tan and others held military discussions to determine how to deal with it.

"South Jin army has failed, with the easy defense and difficult attack of Muling Pass, it is much easier for us to resist two Jin soldiers. If we can defeat the other Jin army, the situation will be even more optimistic." Liu Qingfu is more warlike and advocates taking action with the Red Turban Army.

Zheng Yande was relatively calm and said, "We don't know whether the news of the Red Turban Army defeating the Jin army is true. It's still a bit reasonable to rely on the risk and stick to it. Is it a bad thing to go out of the way to fight, right?"

Li Quan turned his attention to Guoan and wanted to hear his opinions. After all, he had fought with the Jin army in Anqiu, so he should know a little about the reality of the Jin army.

Guoan Yong was timid and belonged to the war-avoiding faction. Seeing Li Quan's gaze, he thought for a while and said, "I think General Zheng's words are reasonable. Besides, if we don't leave the gate, we will confront the Jin army, and the Red Turban Army will cover the killing from behind. It's different to attack!"

Li Quan shook his head gently and said, "This is different. If the Jin army turns around and fights the Red Turban Army with all our might, we will not come out of the gate to respond. Well, the Red Turban Army is also worried about this?"

"Yes, if we can't say anything, we just wait for the Red Turban Army to arrive and attack forward and backward, the Red Turban Army may not be able to believe it easily." Li Fu nodded, agreeing with his brother's statement, "The Red Turban Army and Yang Miaozhen have joined forces. I guess it's because of their great strength that they dare to fight against the Jin army, right?"

"Yang Miaozhen's defeated generals may not be of much help to the Red Turban Army." Yu Yang shook his head and said, "We have been in Qing, Wei and other states, and we really don't know much about the Red Turban Army. If the Red Turban Army can occupy the three states, this strength cannot be underestimated."

"Will the Red Turban Army be on par with Liu Erzu, Peng Yibin and other rebels and fight in joint operations, how can the Red Turban Army be easy to deal with?" Yu Tan agreed with his brother's judgment and said, "It is not clear in the letter that Liu Erzu and other rebels have also taken action to restrain the Jin army and support our army."

"Yes!" Liu Qingfu thought of this incident and immediately became bolder and strong, saying, "If you don't even dare to leave the gate, wouldn't it be a joke?"

"What the letter said may not be true." Guoan curled his lips and said, "They said they were restraining the Jin army and supporting us. Isn't it beneficial to them to attract the main force of the Jin army at Muling Pass? If Muling Pass fails to protect, the main force of the Jin army will go south to attack the Red Turban Army. They are naturally anxious and naturally hope that we will fight for our old capital and fight to death with the Jin army!"

"You can't say that." Li Quan waved his hand and said, "The Jin army is our enemy, and it is our territory. It is already very kind to the Red Turban Army to lend a helping hand. Of course, if we are defeated, they will not feel good. This is called..."

"The lips are dead and the teeth are cold." Li Fu continued and said, "The Marshal is right. The Jin army is the enemy. Even if we are defeated and have no way to join the Red Turban Army, they will probably give us some rice as if they were in Yang Miaozhen's troops."

"Meng Jiucheng's reputation is not obvious, but he has never heard of his bad deeds." Li Quan touched his chin and said, "As for the enlistment, that is a matter for the future. Now, we should focus on stability and defending Muling Pass is also beneficial to the Red Turban Army. If we go out of the pass to fight, it is better to explain our difficulties to the Red Turban Army. Don't take risks for the time being."

"The Marshal is right, be steady, be steady." Guoan nodded repeatedly and echoed: "We have kept Muling Pass tightly, but it has restrained the two Jin troops and has the greatest effect."

When Liu Qingfu and others saw that Li Quan had made the decision, they stopped insisting and said they obeyed orders.

"That stone thrower is a good thing, which can be comparable to the bows and arrows of the Jin army." Li Quan said again: "There are still craftsmen in our army, so I will imitate them as usual. I will write a letter and borrow some from the Red Turban Army. In this way, I will be more confident in defending Guancheng. By the way, I will send some gold, silver and wealth to express my gratitude to the Red Turban Army."

Li Fu nodded in agreement. This is indeed the best way to not offend the Red Turban Army, and to defend the city and maintain an independent position.

These discussions and countermeasures were naturally something that happened a few days ago, and Meng Jiucheng had already completed the discussion with the generals and made corresponding adjustments based on Li Quan's movements.

Although Li Quan was unwilling to send troops out of the pass, the Red Turban Army annihilated the Jin army in the South Road and supported the stone throwing machine, which really gave them the confidence to stick to Muling Pass.

With the dangers of Muling Pass, as long as the morale of the army is not chaotic, even if the Jin army attacks in two groups, it will be difficult for them to easily break through the pass.

Therefore, the Red Turban Army can dispatch troops, but try not to fight head-on with Wanyan Eren, but instead restrain the harassment so that it cannot work hard to solve the problem.

As long as the Jin army was held, they could not hold on for too long with the food and supplies they carried. They suddenly fell under the strong city and lost again. Wanyan Elun's troops became an isolated army and the defeat was decided.

According to the planned plan, the Red Turban Army will dispatch two battalions of troops to set up camps and villages in Kushan, posing a threat to Wanyan Elun's flank.
