After the Youyan army suppressed the forbidden troops around the Yanshi, they immediately set up camp and began to dig tunnels under Qiu Yi's men.

Zheng Rong was afraid that the bombardment of the city wall would cause innocent people to be killed and injured, so he used crossbow arrows to shoot the Anmin notice into the Yanshi city wall early, saying that the Youyan army was about to attack the city. The people of the city were given three days to leave through the gates of the city wall, and they were not hindered from the pursuit.

Zheng Rong is known as a benevolent name in the Han Dynasty and the opposition, and after receiving the notice, the Yanshi people immediately sorted out the softness, helped the old and the young, and it only took two days to turn a rather lively Yanshi City like a ghost town.

However, the Yanshi county order still has some integrity, and he personally led three or four hundred officers and soldiers in the city to guard the city wall day and night.

Zheng Rong's side.

The eighteen bandits under Qiu Yi's command actually didn't really learn the skill of digging tunnels, but fortunately, there were 30,000 Youyan troops behind them, and some of them were strong laborers. Therefore, the excavation speed is much faster than that of Shi Dajian.

However, their ability to orient and identify positions underground was a little worse, and they were originally going to dig next to the west gate of the Yanshi City Wall, but they finally dug to the foot of the city wall in the northwest, but it was not a big problem.

So Qiu Yizhi selected dozens of confidential and careful soldiers in the army, and carried all the 500 catties of gunpowder he had prepared in advance to the end of the tunnel. After lighting the fuse himself, he ran to the exit of the tunnel, lest the tunnel collapse and bury himself alive.

Unexpectedly, after Qiu Yizhi came out of the tunnel, after a long time, the gunpowder under the Yanshi did not explode for a long time.

Just as Qiu Yizhi thought that the flame had failed to ignite, and was about to go back to the cave to re-examine, he suddenly saw a cloud of dust raised under the Yanshi City, followed by a shaking of the ground, and a deafening loud sound followed.

This movement was much more earth-shattering than when half of the Jianchun Gate was blown up in the capital, and even someone as mentally prepared as Qiu Yizhi was taken aback and hurriedly subconsciously prostrate on the ground.

The other soldiers who saw such a scene for the first time were even more at a loss, and they were also busy learning the appearance of Qiu Yizhi and lying on the ground, not daring to raise their heads.

This was followed by countless broken bricks and stones that had been blasted into the sky by gunpowder. They were hit into the sky by the tremendous force generated by the explosion of gunpowder, and they scattered and fell in all directions irregularly. Many of them flew into the Youyan army formation and smashed more than a dozen officers and soldiers into bloody battles.

Qiu Yizhi didn't expect that five hundred catties of gunpowder would have such power, Rao was bold, but it took a long time before he got up from the ground in shock and carefully observed the situation of Yanshi.

It turns out that when gunpowder explodes, in addition to the fact that the formula must be accurate and the dosage is as sufficient as possible, it is best to have a sealed environment when detonating. When Qiu Yizhi used gunpowder to blow up the Jianchun Gate, although the gunpowder was tightly wrapped with linen, the explosion occurred in an open place; Today, it was detonated in a well-sealed tunnel, and of course the power was worlds apart.

Where did Qiu Yizhi know the scientific truth of this, it was just a blind man's coincidence, but he also came to the conclusion that gunpowder must be detonated in the tunnel in order to exert the maximum power.

While Qiu Yizhi was carefully observing the situation of Yanshi, it rained at the right time.

At first, it was just a sporadic light rain as thin as a cow's hair, but then the rain became heavier and denser, and it began to rain in a decent manner.

It was this rain that gradually washed away the dust and the pungent smell of sulfur in the air. The Youyan soldiers, who were crawling motionless on the ground, couldn't stand the chill brought by the rain, so they slowly got up cautiously and observed the situation in front of them.

Zheng Rong's identity is precious, and what he pays attention to is that Mount Tai collapses in front of him and his face does not change; Seeing that he is going to ascend the throne as the emperor again, the city government is getting deeper and deeper; And the guards around him used the big shields of the camp to defend him against falling rocks—so he stood there calmly, looking very calm.

Qiu Yizhi did not have this temperament, seeing that the smoke and dust in front of Yanshi City gradually settled, he hurriedly wiped the dust and mud on his body, and ran to Zheng Rong's side, and reported: "Father-in-law, the Yanshi city wall really collapsed, it was detonated and collapsed by gunpowder!" ”

Zheng Rong deliberately suppressed the excitement in his heart, nodded quietly, and said, "Lone has seen it." You will order Cui Nan and Zheng Sen, each with 10,000 leading troops, to break into the city through the gap in the city wall and occupy Yanshi. And don't attack the people, and those who violate it will not be spared! ”

The defenders of the Yanshi were originally not very confident in holding the city under the siege of Youyan's army, but they were frightened by this sudden huge movement, where did they still have the heart to organize a defense? When they saw the Youyan cavalry and infantry pouring in from the gap in the city wall, they had already dispelled the idea of resisting, and they threw down their weapons and gave up resistance before they fired an arrow.

Seeing that the city had been broken, the Yanshi County Commander committed suicide by hanging the beam in the back hall of the county government.

Zheng Rongping likes Qing officials and tough guys the most, and when he saw that Yanshi County Commander had such integrity, he secretly admired it in his heart, so he made people generously sympathize with the widow of the county commander and rewarded him with a large amount of gold and silver.

After a little handling of Yanshi's affairs, Zheng Rong couldn't wait to come to the gap in the Yanshi city wall and carefully observe the gunpowder bombardment.

I saw that the explosion of this gunpowder was really powerful, and the entire corner of the Yanshi city wall was blasted away, leaving a large gap for more than ten people to pass side by side. The bricks and timber that were originally used to build the city walls have been blown to ashes and scattered scattered all over the ground in an orderly manner.

So Zheng Rong asked Zhong Li Kuang: "Sir, can the gunpowder equipped with the instrument collapse the Luoyang city wall?" ”

Zhong Likuang had seen the power of gunpowder, but he was still deeply shocked by the energy generated by the explosion of these five hundred catties of gunpowder in the ground today.

Zhong Li Kuang listened to Zheng Rong's question, pondered for a while, and said, "The students have also read some of the classics of the Tianzun Sect hastily. The people of the Western Regions fought very few field duels, and paid attention to building fortresses step by step. Therefore, he must be proficient in the method of building walls and cities. In this case, the people of the Western Regions attacked the high walls of the fortified city, and relied exclusively on gunpowder instead of ladders, so it was also feasible to attack the city with gunpowder. ”

Zhong Likuang's ability to reason from the side is unparalleled, and Zheng Rong nodded again and again, and then ordered: "Zheng Xin and Wei Hu led 10,000 troops, stationed in Tongguan and controlled the military and political affairs of Youyan and Henan, and must ensure that the supply of grain and grass is on time and in full; Zheng Sen, Zheng Miao, and Cui Nan each led 20,000 troops, swept the officers and troops near Luoyang, and blocked the Dasan Pass to prevent the Qinwang troops from entering the pass; Alone led the army of 30,000 troops, and attacked Luoyang with Mr. Zhongli and Qiu Yi! ”

The herald soldiers beside Zheng Rong listened to the order, and repeated it with their fingers crossed, but it was not a word for word. Zheng Rong was happy to hear this, so he asked him to drive the horse and give the order immediately.

Qiu Yizhi said again: "Did the righteous father also make a will, just say that the Yanshi city wall was collapsed by the thunder." First, it is to cover people's eyes and ears, and secondly, it is also good to show that the righteous father is destined to return! ”

When Zheng Rong's mind as the emperor was hot, Qiu Yizhi's sycophant was just right, which made him immediately smile, and he rarely praised it: "There are many ideas to save you Qiu Yi's ghosts." Okay, it's up to you to let the people below spread the rumors. ”

The Youyan army divided into four directions and swept through.

Zheng Miao, according to the instructions of his father Zheng Rong, bypassed the capital Luoyang all the way, and fought all the way to the west of Luoyang, but did not attack the city pass, but only fought under the pass.

After receiving the will of Emperor Zheng Yao, from Shanxi, Bashu and other places, those who planned to enter King Qin of Luoyang through the Dasan Pass were all Jiedu troops from all over the country, and their combat effectiveness was already weak. However, due to the situation, the Jiedu army in these places had to go out of the customs to challenge the Youyan army led by Zheng Miao.

Zheng Miao's use of troops is quite similar to his father, he pays attention to being upright, steady and steady, and is fully prepared, and he fights a battle of waiting for work.

Therefore, after the two armies clashed, Zheng Miao did not even let the Jiedu army see the slightest hope of victory, and drove it back to Dasanguan without much effort.

In this way, although the Dasanguan was still nominally in the hands of the imperial court, it had been completely blocked. Coupled with the Tongguan guarded by Zheng Xin, the entire Province has been blocked by the Youyan army at both ends, becoming a dead land.

Speaking of the forbidden army in, after the defeat in Henan, they were taken down Tongguan in another day, and they have become like frightened birds - together with the Youyan army, they were immediately defeated, Zheng Sen, Cui Nan and others did not even have a chance to find a chance to encircle and annihilate.

However, the two gates of were firmly guarded by the King of Youyan, and the forbidden army had no choice but to move closer to Luoyang in order to keep warm. However, Emperor Zheng Yao had already decreed that all troops outside the city could not enter Luoyang, and could only camp outside the city.

Luoyang City is built on the fertile Guanzhong Plain, and there are endless fields except for a few small hills nearby, which is really unsafe. Therefore, the broken forbidden army could only establish a large camp under the Pingchang Gate on the south wall of Luoyang.

So Zheng Rong found the right opportunity, commanded Zheng Sen and Cui Nan, attacked the camp from the east and west, and personally led the army to attack head-on, taking advantage of the fact that the forbidden army was not stable and launched an attack.

The morale of Youyan's army was flourishing, while the morale of the court officers and soldiers was declining. In this way, the forbidden army had no power to fight back, so they withdrew from the camp that the military department had painstakingly built, and all retreated to the Pyeongchang Gate, waiting to enter the city.

At the time of the war, the emperor Zheng Yao was watching the battle on the city wall, lest the city gate be opened, and the Youyan army would also follow the defeated soldiers into the capital, so he strictly ordered not to open the door and let a soldier enter the city, only to order the officers and soldiers on the city wall to shoot at the Youyan army as cover.

In this way, the forbidden army outside the city continued to wait outside the Pyeongchang Gate to "wait for death", and turned to face the Youyan army to "find death", and they really reached the end of the road and sat back to die.

Unexpectedly, at this moment, the Youyan army stopped attacking, but instead took a few steps back, calmly arranging a formation about a hundred steps in front of the frightened forbidden army.

But I saw a military general wearing a golden armor and red robe, sweating and bloody BMW under his crotch, under the escort of the elite warriors around him, he slowly came out of the battle, coughed lightly, and said loudly: "Down is Zheng Rong, the king of Youyan!" ”

As soon as Zheng Rong's words came out, the battlefield where the sounds of killing and screaming were mixed suddenly quieted, and nearly 100,000 troops on both sides on the battlefield were silent and listened to him.

I only heard Zheng Rong continue: "Lone is the son of the first emperor, the younger brother of the Daxing Emperor. It was only because Zheng Yao was rebellious and usurped the throne that he had no choice but to send troops to rebel. Lone is not a person who loves to kill, and the soldiers of the forbidden army are also my people, so how can Lone bear to kill and hurt. Those who abandon the darkness and turn to the light will be accepted by nature; Those who go home to farm will not be hindered by loneliness; If you are obsessed, you will let it go. Lone will retreat the army a mile, Rong Er and others think twice, if there are still stubborn resistors tomorrow, don't blame Lone Jade and Stone! ”

With that, Zheng Rong turned his horse's head and returned to the Youyan army.

As Zheng Rong said, the Youyan army slowly retreated.
