At the same time as the Jingbei Army opened its net to fish, Zhang Xianzhong, the eighth king, plunged into the Dazhu River in Taiping County under the attack of Zuo Liangyu and He Renlong.

Zhang Xianzhong wanted to retreat to Daba Mountain, but Zuo Liangyu didn't give him any chance at all, he took his son Zuo Menggeng to command 3,000 troops as the left wing, and Wang Yuncheng also commanded 3,000 troops as the right wing, and took the lead in cutting off Zhang Xianzhong's escape to Daba Mountain.

With no way to escape, Zhang Xianzhong had to move to the Jiuluanping area of Wanyuan County.

However, Jiu Rolling Ping is also helpless, and it is not enough to resist Zuo Liangyu's army at all, but the combat effectiveness of the peasant army is very different from that of the official army, and it is not enough to fight against the official army without the help of external forces.

With no way back, Zhang Xianzhong chose the safest, but also the stupidest plan, that is, to lead the army to Agate Mountain.

Agate Mountain is only more than 20 miles in circumference, more than 40 zhang high, three sides are full of steep cliffs, only the foothills of the southwest direction are slightly gentle, can be used as a passage into the mountain.

After Zhang Xianzhong went up the mountain, according to the terrain, he dug two trenches along the foothills of the mountain, piled up three mud walls, and inserted sharp wooden stakes outside the trenches, sprinkled with thistles, and prepared countless rolling logs and stones behind the mud walls.

The whole line of defense is strict and orderly, it can be said that it is a one-man pass, and it is impossible to open it, but although the defense line is repaired very safely, Zhang Xianzhong ignores the problem of grain and grass, he marches lightly, that is, he breaks the state and county, and does not dare to carry too much baggage on the road, and the current army is only more than 20 days of rations.

Zuo Liangyu for the thief general seal, and I am afraid that he will be robbed of the credit by He Renlong, all the way forward, when receiving the news of the sentry, Zhang Xianzhong actually rushed into the Agate Mountain, is to leave the people with the army, and strictly ordered the departments to quickly move closer to the Agate Mountain.

On December 15, when Zhang Xianzhong had just set up the defensive line, Zuo Liangyu's banner had already been planted at the foot of Agate Mountain.

Zuo Liangyu was determined to forge ahead, and as soon as he arrived at the bottom of the mountain, he took the generals to observe the terrain, and he found that although the mountain of Agate Mountain was steep, although it was a dangerous place, but it was a dead place, so he discussed with his son Zuo Mengeng, guerrilla Wang Yuncheng, Lu Ding and Jin Shengheng and others to attack the mountain.

The generals are also old soldiers, but they are terrified after seeing the terrain of Agate Mountain and Zhang Xianzhong's defense line.

"Father, this mountain is so dangerous, the thieves are guarding it, our army is only 20,000, if it is attacked, the child is afraid that it will be filled in, and it may not be able to take Zhang Xianzhong."

"Marshal, what the young general said is that although the general of the thief is in a high position and the president has a large army from all walks of life, it is just a false name, and the 20,000 tigers under our command are the capital of the marshal's life, if you fight with the thieves, it will be difficult to train another elite soldier."

Zuo Mengeng's views have been supported by Wang Yuncheng and Lu Ding and other generals, after all, in these years, holding a knife in his hand is the last word.

"Hehe, you only know one thing, you don't know the other, Meng Geng, my father often tells you, you have to read more military books and war strategies, instead of blindly fighting bravely, now the thief is only under our horses, and you can't have a plan to follow."

Zuo Liangyu was a little worried about himself, a martial arts son, if he only relied on brute force to fight, then his 20,000 tiger ben could withstand several battles.

"Father, does he have a way to deal with the thief?"

Zuo Mengeng is not stupid, he will already react.

"Brothers, please see, although Agate Mountain is easy to defend and difficult to attack, but the dangerous place is the Jedi, can you know the Battle of Jieting during the Three Kingdoms period?"

"Uh...... Father, I understand, now Zhang Xianzhong is the horse who entered the mountain, and we are Zhang He, who came from the double road, as long as we block the road down the mountain, and the thief has no food to replenish, his army will run out of food in less than half a month. ”

Zuo Mengeng has been in the army for many years, and he is not ignorant of military affairs, Zuo Liangyu mentioned it slightly, and immediately understood the key points.

"Don't inform He Renlong, this time the commander wants to capture Zhang Xianzhong alive, and the generals will listen to the order."

Zuo Liangyu pointed at the tip of the whip and resolutely issued a military order to fight.

"Jin Shengheng, you command a thousand troops, stationed in the east of Agate Mountain, Lu Ding, Wang Yuncheng, you two also command a thousand troops to guard the north and south two places, Meng Geng, you and your father garrison the southwest corner of Agate Mountain, thinking that it is a plan to encircle on all sides."

"Oh, the last general will obey the orders of the general!"

Zuo Mengeng took the lead in bowing down, and there was no need to attack, so naturally there would not be many people lost, so everyone would be happy.

"Of course, when the armies are stationed, they must block the roads, investigate closely, bring the Minfu brigade up, and ask them to set up wooden fences and watchtowers, thinking that it is a long-term solution, as for He Renlong's side, don't inform them, this commander will have the merit of exterminating Zhang Xianzhong."

Under Zuo Liangyu's strict orders, the officers and troops quickly moved into action, and the troops began to camp at the same time.

The movements of the official army, Zhang Xianzhong on the mountain saw it clearly, at first he thought that Zuo Liangyu was tired from afar, and this was to rest and fight again.

The next day, after the militia of the left army arrived on the battlefield, Zuo Liangyu quickly launched an action.

More than 17,000 officers and troops stationed at the southwest corner of Onyx Mountain were almost all dispatched, and positions were set up at various intersections at the foot of the mountain.

However, the formation of this army was very strange, and it was actually a defensive posture with sword and shield soldiers in front, pikemen in the rear, and musketeers and archers on guard on both flanks of the official road.

"What kind of trick is Zuo Liangyu playing, Lao Tzu is on the mountain, he is actually patient and does not attack our defense line?"

Zhang Xianzhong frowned, his long-term combat experience told him that the current situation was a little inappropriate, but he couldn't say what the specific reason was, Luo Rucai led the army to Wushan, so that the peasant army lost one of the best commanders and think tanks.

"Father, the child thinks that the left thief wants to block us on the mountain."

Zhang Dingguo, who followed Zhang Xianzhong, showed his good military talent.

Of course, the current Zhang Dingguo is not the invincible god of war who slashed the puppet Qingjing Prince Nikan ten years later, burned the king of Dingnan, Kong Youde, surrounded Xinhui with soldiers, and beat the puppet Qingping Nanwang Shang Kexi who issued eighteen urgent documents in seven days, and he only knew the current situation in hindsight.

"Uh......!"

Zhang Xianzhong was shocked when he heard this, he is also a general who has been in command for a long time, and after a little mention, he understood Zuo Liangyu's tricks, but there was still a trace of luck in his heart, and he hurriedly looked down the mountain.

I saw that after the official army was in a big array, countless people were like ants carrying grain, constantly carrying wood back and forth.

More people are digging trenches, building wooden fences, laying out defensive lines, and arrow towers and watchtowers are springing up like mushrooms after a rain.

The wooden fences slowly approached behind the large array of officials and troops at a speed visible to the naked eye, and the people even followed their own defensive line and laid a large number of sharp stakes outside the trenches, and the gate facing the official road was also full of hastily made antlers.
