Before the construction of Yokohara Fort, Wanjia Fort was the biggest defense in the mountains and the most important fortress of the Perak Army. The field battalion of the Perak Army was defending the construction of Hengyuan Fort and various cantonment points in the plains during this time, and the internal guard battalion also had reconnaissance and guard tasks, so Ouyang Xuan dispatched the teaching company stationed at Wanjiabao to quell the rebellion. In order to ensure that nothing went wrong, Ouyang Xuan asked Yu Zhu to urgently recruit soldiers from two companies of the garrison battalion in Wanjiaping. These soldiers were all industrial workers in various mines and factories in Wanjiaping, and their daily military training level was more than enough for the fort and logistics baggage troops. After leaving Yu Zhu and a company of the garrison battalion stationed in Wanjiabao, Ouyang Xuan took the teaching company and another company of the garrison battalion that was urgently recruited to the direction of Wandanping. In fact, not long after they set out, they saw the vanguard of the rebels from afar.

At noon, when Linde and the rebels marched to the intersection of Liuliba and Wanjiaping, the scouts who had gone out to reconnoiter brought back the military information of the Thunderbolts coming towards them from Wanjiaping. This sudden news shattered a wave of panic in Linde's heart, and he knew that his raid plan had failed. However, this Linde is also a person who licks blood from the knife edge, and in a moment he stabilized his mind and ordered the whole team to immediately turn to the Liuliba. To say that Linde's decision was not wrong, in the case of the loss of suddenness of the attack, as a guest army, it is obviously not appropriate to fight with the Thunderbolt army, but should retreat to the favorable terrain as soon as possible. Different from Wandanping, which is short of materials and has no fortifications, Liuliba is obviously a better choice. In terms of long-term stubbornness, Liuliba is second only to Wanjiaping in Jiguan Mountain. After Lin De entered the mountain, he had nothing to do every day but eat, drink and sleep, but in fact, he was studying the Thunderbolt Army and Ouyang Xuan. He knew that Liuliba, which started as the Thunderbolt Army, was not only easy to defend and difficult to attack, but also had mines and workshops for making firearms, as long as he captured this place, he could defend it with firearms, and he would have the capital to compete with Ouyang Xuan.

Ouyang Xuan and Huang Dagen saw the rebels heading towards Liuliba from a distance, and while ordering the teaching company to chase at full speed, they also ordered people to go back to Wanjiabao to release carrier pigeons. Carrier pigeons are only fed in important military and political places or important stockades, and are not suitable for marching and fighting. This Linde's men were elite and lightly armed, and they marched extremely fast. On the other hand, although the Teaching Company was also the elite of the Thunderbolt Army, it was much slower because of the baggage it carried with artillery, spears, and giant shields. After catching up for a while, the distance between the two sides is getting bigger and bigger. However, Ouyang Xuan also understood that the pursuit of the mountain road would not reach the speed of the pursuit, and he did not order the pursuit at full speed. If the teaching company left behind the artillery and heavy equipment and marched quickly, without firearms, even if it caught up, it would not be a match for the rebels. Even if they were lucky enough to defeat the rebels in hand-to-hand combat, they would inevitably suffer heavy casualties, and the Thunderbolts could not afford such losses. He prayed in his heart that the defenders of Liuliba would receive the news from the flying pigeon and prepare for the battle in time.

Although Liuliba received the warning signal from the flying pigeon, it was still caught off guard. Because at this time, Lin De and his people had already marched to two miles in front of the walled gate. Liuliba originally had a company of the garrison battalion, but during this time, a platoon was transferred to build Yokohara Fort, and most of the rest went up to the mountains to farm and hunt, and in fact, the strength of the guard was only one squad. To say that this arrangement was originally not wrong, after all, if the enemy outside the mountain wants to attack Liulizhai, he must take Wanjiabao and Hengyuan Fort, where the main project has been completed, and this situation obviously will not occur at the same time. It is obviously more than enough to deal with small-scale infiltration and spies with the strength of one squad, so the garrison company commander of Liulizhai is relieved to take people into the mountains to hunt, and he will not be able to come back in a short time. There were too many refugees pouring into the mountains during this time, and the pressure on food was very great, so he took his brothers to hunt some wild beasts to help Brother Xuan relieve some pressure.

The squad leader who stayed behind in Liulizhai was called Dong Shishi, and he looked at the long line of rebels on the mountain road below, and panicked for a while. He knew that his class would not be able to defend Liuli Village no matter what. There were two cannons on the wall, but neither he nor his brothers had operated them themselves. This Dong Shi was in a panic, in addition to desperately ringing the gong to warn, he was just jumping on the wall in a hurry, watching his soldiers fiddle with artillery indiscriminately. The rapid sound of gongs suppressed the clanging sound of the industrial area behind the wall, and then the workers walked out of the workshop to see what was going on. After the Perak Army took Wanjiaping as its headquarters, it still regarded Liuliba as an important military industrial area, and there were still cannon foundries, shield spear workshops, and even a new water-powered musket barrel stamping workshop in the industrial area of the first walled wall. After the second wall, in addition to the residential area and the mine, there was a gunpowder workshop and a grenade assembly workshop in the middle of nowhere, near the side of the mountain. There are hundreds of industrial workers in the whole Liuliba, and if you add the convicts who served hard labor in the mines, the number of people engaged in industrial and mining is as high as thousands, and it is the industrial center second only to Wanjiaping.

Just when Dong Shishi was so anxious that he was sweating profusely, a large group of workers ran towards the wall, led by a black man with strong muscles. After seeing the person clearly, Dong Shishi jumped up happily as if he had grabbed a life-saving straw, and shouted happily, "Brother Sledgehammer, you are too good to come." It is no exaggeration to say that Hu Blacksmith and his blacksmith shop are the predecessors of the industrial company, and his three sons are also one of the patriarchs. With the industrial layout of the Perak Army, Hu Blacksmith and the other two Hu Erhammer and Hu Sanhammer went to Wanjiaping, Huaguoshan and other places respectively, and only Hu Dahammer stayed in Liuliba. Now he is mainly responsible for gun casting. Hu Dazhui led people to walk up to the wall, he looked at the rebels who were getting closer and closer, and briefly asked about the situation, and then directly commanded. He ordered a few workers to be responsible for operating the artillery, and ordered people to go to the grenade assembly workshop to pick up the grenades, while the rest of the workers moved the important tools and items of the factory behind the second wall, especially to give priority to the handling of the barrel blanks. Dong Shishi not only did not have the slightest disgust at Hu Dazhu's transgression, but was relieved and took a long breath.

As soon as the rebels came into range, they were unsurprisingly hit by artillery fire. It's just that due to the rapid march, the rebels' marching line is very long, and there are not many people who come into the range of artillery. The level of the workers in handling the artillery is really not comparable to that of the professional gunners, so in this round of two shellings, the rebels only killed and wounded a few people, and this killing effect is even worse than the Mongols' rain of arrows. Linde took the opportunity to agitate loudly, saying that only by moving forward can there be a way to live, and that stopping and retreating is death, and his subordinates also understand this truth. Since ancient times, the punishment of those who have failed in rebellion has been extremely severe, and now only by fighting to the death can we survive.

To say that these rebels are worthy of being elite, after three rounds of shelling, they rushed under the wall, and only lost more than 20 people. They rushed to the bottom of the wall, braved the explosion of grenades, and shot arrows one after another, although more than a dozen people were blown down, they still did not retreat. Linde's rebel army was a typical Song army, with more than 50% crossbowmen. Nearly 100 archers released arrows at the same time, and for a time the feathered arrows on the wall flew wildly. Although it was protected by stone saucers, the guards on the wall were still hit by arrows and fell to the ground, killing and wounding more than ten people in a short time. What's even worse is that Dong Shishi's squad is a second-line unit, and the ten people in the class are only equipped with a dozen old-fashioned grenades, which can't withstand throwing at all. Without the suppression of grenades, the rebels' crossbow arrows became more and more violent, and the guards were suppressed so that they did not dare to show their heads at all. Hu Dazhui saw that he could only be shot passively if he stayed on the wall, and the wall could not be defended, not to mention that it would only increase casualties, so he ordered to withdraw to the second wall.
