Soon after Zhao Shicai led a large group of men and horses towards Wanjiazhai, Shi Zhongshu quietly sneaked out of the underground warehouse of Wanjiabao with his soldiers and made a move against the new annexed army left behind. The entrance to this underground warehouse was not obvious in the first place, and the Thunderbolts made a careful camouflage, and the new annex army was busy arranging defenses after occupying Wanjiabao, and did not find that there was still an underground warehouse in this fortress. So when the soldiers of the second company launched a surprise attack, the soldiers of the new annex army who stayed behind were completely stunned, and in the blink of an eye, they were beaten and scattered in all directions, but they found that there was no way to escape, so they had to kneel on the ground and beg for mercy. Only a dozen or so soldiers of the new annex army guarding the back gate saw that the situation was not good, and they jumped from the city wall at the risk of death but were beaten and tied up by the Thunderbolt soldiers who chased them, only two of them were vigorous, and after getting up, they limped and fled in the direction of Zhao Shicai.

The recapture of Fort Wanjia went as smoothly as expected. In addition to the two who escaped, only a dozen or so of the new annexes guarding the fort were slightly wounded, and six diehards were killed, and the rest were taken prisoner. On the Thunderbolt side, only four people were slightly injured. In fact, the number of soldiers on both sides is the same, and there is not much difference in individual combat strength. In the case that the Thunderbolt Army did not use firearms, the battle results could be so disparity, in addition to the fact that the new annexed army was caught off guard by the surprise attack, another important reason was that most of the soldiers of the new annexed army were confronting the new annexed army of Qingcheng County at the head of the wall, and they did not expect that there would be a sneak attack behind them.

After the new annexed army of Qingcheng received the news from the Mongolian centurion that Zhao Shicai had captured Wanjiabao and was moving towards Wanjiazhai, they hurried to Wanjiabao while speeding up their march. The battle situation ahead was unexpectedly smooth, so that the new attached army of Qingcheng, who was eager to share the credit, changed their procrastination style, and rushed to Wanjiabao in a short time, but they were closed. No matter what you say, Zhao Shicai's subordinates just don't open the door. In addition to asking each other's ancestors and female relatives, the new attached army of Qingcheng County also scolded Zhao Shicai and his gang for being too dark-hearted, and they didn't even prepare to leave a bite of soup for their allies when they ate meat; The new attached army of Dayi County scolded the other party for being a turtle with a shrunken head, and it was not good to march and fight, but it was the first place to grab credit. scolded in a hurry, the new attached army of Qingcheng County began to take a ladder and hang a rope and began to climb the wall, but the cement paste city wall was smooth and abnormal, and it was impossible to climb up with only a rope, and the ladder was pushed down by the new attached army of Dayi.

In the process of climbing the wall, the soldiers of the new annexed army in Qingcheng fell and injured several people, which made the quarrel between the two sides become gunpowder. It's just that although the number of new troops in Qingcheng County is four times that of the soldiers guarding the fort, there is nothing to be done in a hurry. Just when the two sides were looking at each other angrily, the Mongolian hundred-man team arrived in battle. The centurion of the Mongolian army was a Khitan, and he spoke Chinese fluently, and under his angry scolding and reprimand, the officer of the new annexed army of Dayi, who was in charge of guarding the fort, could not care about Zhao Shicai's order, so he issued an order to open the front door of the fort. However, although this order was sonorous and powerful, it was not carried out. Because just before he gave the order, the second company had quietly launched a surprise attack. The surprise attack of the Thunderbolt soldiers was not silent, but the sound was drowned out by the shouts of insults and shouts from up and down the city walls. This had allowed the soldiers of the second company to quickly control the winch that opened the gate, and also dealt with the new annex in the fortress. At the moment, they were rushing down the stairs towards the city walls.

Under the city wall, the new annex army and the Mongols of Qingcheng County saw that there was a fight on the city wall, and the shouts of killing were everywhere in the fortress, but they didn't know that it was a surprise attack by the Thunderbolt army, but thought that there was infighting among the soldiers guarding the fort. However, this Mongolian centurion was very decisive, and he knew that there was a change, so he ordered the arrows to be released, and at the same time ordered the new annex army of Qingcheng County to attack the city. Braving the rain of arrows, Shi Zhongshu commanded the second company to deal with the new annexes on the city wall and block the new annexes who climbed the wall. Fortunately, at this time, the new annexed troops on the city wall were crowded together and could not talk about the formation at all, and the will to fight was not strong, after a column of the second company charged and stabbed a few people to death, the rest of the people knelt down and surrendered, and the new annexed troops of Qingcheng County who climbed the wall were also blocked back.

While the two sides were fighting fiercely on the wall, the Mongols rained arrows, and although most of the arrows were blocked by the wall saucers, many of them still landed in the ranks of the Thunderbolts. Compared with the inferior bow and soft arrows of the new annexed army, the arrows fired by the Mongol soldiers were fast and accurate, and in the blink of an eye, more than a dozen Thunderbolt soldiers were hit by arrows. Although the rattan armor on his body blocked most of the vital points, two soldiers were still shot in the face, and their faces were covered in blood in an instant. Of course, the influx of feathered arrows also hit many of the new annex soldiers, which was not a pity in the eyes of the Mongols, because in their eyes the new annex was not a friendly army, but only cannon fodder.

After clearing the new annexes from the walls, Shi Zhongshu sent people to the underground warehouse to get gunpowder and cannonballs, which he wanted to use against the Mongols. The Mongol centurion had now understood that he had lost the opportunity to retake the fortress, and he ordered his men to continue to suppress the wall with bows and arrows, while the new annexed army of Qingcheng County retreated to the rear to prepare siege equipment. After a short interval in battle, the new annexed army of Qingcheng County rushed towards the city wall with several more ladders. Due to the narrowness of the mountain road and the inability to carry and deploy large equipment, the new annex army only brought light siege equipment into the mountain this time, including the latest siege ladder. This kind of ladder has a triangular bracket at the bottom, and the curved iron hook at the top can be firmly attached to the wall, which is not as thin as an ordinary long ladder. However, even with the siege ladder, the soldiers of the new annex still could not climb the wall, because the battlements at the head of the wall could pierce spears at any time to harvest their lives.

The new annexed army of Qingcheng County under the city is under the persecution of the Mongols, and waves of ground ants are attacking the city. These soldiers were also reluctant to come forward to die, but the Mongols were ruthless, and after killing a few people in a row, these cannon fodder had to raise their shields and move forward. It's just that under the fierce counterattack of the second company, the waves of offensive of the new annexed army in Qingcheng County were defeated and retreated like a tide. Only the officer who led the team and more than a dozen personal soldiers held shields and slashed the fortress gate with giant axes. It's just that the gate is extremely thick and strong, and sparks are flying, but the gate is still intact, leaving only a shallow mark on the steel plate on it. The officer who led the team did not go back, because he knew that if he returned, he would die by the sword of the Mongols. In the first few rounds of attacks, more than 20 soldiers of the new annexed army died under the sword of the Mongol warlords, but more than those died under the city.

At this time, in Wanjiabao, the soldiers of the third, fourth, fifth, and sixth companies of the field battalion were resting in a secluded place. When Zhao Shicai left Wanjiabao with a large group of men and horses to attack Wanjiazhai, the soldiers of these four battalions, under the leadership of Ouyang Xuan and Cao Ergou, hurriedly marched to Wanjiabao from the nearby Daping Village. These four companies had assembled in advance at Dapingzhai, five miles away, the day before, and the task was to join forces with the second company that had been ambushed to recapture Wanjiabao in order to form a situation of closing the door and beating the dogs. It's just that he didn't expect that Zhao Shicai's defenders left in Wanjiabao were really collapsed, and they collapsed in an instant under the surprise attack of the second company.
