In the cold wind of the night, several boats quietly stopped to the shore. It is located ten miles upstream of Meizhou City, and there are no people in a radius of several miles. A small group of soldiers in Mongolian attire disembarked from the ship, took off their horses from the transport ship, loaded their saddles, and rode towards the city of Meizhou. This horse team was not a Mongolian cavalry, but a squad led by Yu San himself. This Yu San was the first owner of Xiangshui Village in Jiguan Mountain, and later joined the Perak Army and became a company commander in the field battalion, with some combat exploits. Because he was born in a family of hunters, he was extremely good at sneak attacks, ambushes, explosions and other special combat methods, and in accordance with the principle of making the best use of his talents, he was appointed as the deputy brigade commander and special battalion commander of the Perak Army's internal guard brigade in this army expansion.

The soldiers of Yu San's special battalion were selected from the elite of the whole army, and they were trained in the same way that Wu Qi trained Wei Wushu during the Warring States period, and were equipped with the best weapons and equipment of the Perak Army. Xunzi's "Parliamentary Chapter" recorded: "The military of Wei is taken by degree, the armor of the three genera of clothing, the crossbow of twelve stones, the negative arrow is fifty, placed on it, the crown is with a sword, and the grain for three days is won, and the day is in the middle of the day and tends to a hundred miles." The pilot test will restore its household, and benefit its field Wei Wu's house. That is to say, Wei Wushu must be able to wear triple armor (inner and outer three-layer protective clothing or another name for heavy armor), hold a long halberd in his hand, hang an iron sword at his waist, carry a rhino-faced oar, 50 crossbows and strong crossbows, and carry three days of military rations, and soldiers who can march a hundred miles in a row in half a day can become a soldier. It's just that the soldiers of the special battalion are not pure infantry like Wei Wushu, and they also have to learn to ride horses, and they are equipped with spears instead of halberds, and strong crossbows have also been replaced with muskets.

Participating in the rescue operation this time is still the elite of the special forces. In addition to one man and two Mongolian horses, they also wore Mongolian leather robes and leather armor, armed with scimitars and riding bows, and even water bladders were also Mongolian. In the capture of the Thunderbolt army, there were not a lot of good Mongol cavalry equipment, and it was more than enough to equip a squad. In order not to reveal the identity of the Thunderbolt Army, the action team did not carry firearms, so they selected those who were good at mounted archery and hand-to-hand combat, and the squad leader of the action team, Dunzhu, was one of the leaders.

Dunzhu was originally a fan of the steppe tribe, but in a battle with an armed caravan, he was frightened by the huge momentum of the artillery and was captured, and then together with a dozen companions, he was given to Boss Qian by Zelang as a horse breeder. To say that the strength of this Dunzhu is very huge, and ordinary people can't get close to each other in an unarmed fight. He was able to enter the special forces because of his natural powers. Dunzhu, who grew up on horseback, was no worse than the Mongolians in riding, and also became a horse breeder and part-time riding instructor for the special forces. On this day, when the special forces were learning to ride, a war horse suddenly went berserk, not only overturning the rider on his back, but also biting and kicking, so that he rushed up and subdued the crazy horse. Yu San, who was standing on the side, saw clearly that this horse breeder actually put down this crazy horse with brute force and pressed it to the ground, what a lot of strength! Immediately included it in the special forces. After a period of training, although this Dunzhu is not fluent in Chinese, he has fully adapted to the rules and regulations of the Perak Army, and has been promoted to squad leader based on his strong combat power.

Although the horses had something in their mouths and their hooves wrapped in sackcloth, they trotted forward, but the twenty-two horses of the action squad galloped together, and in the dead of night, they were still faintly like thunder. When there were still three miles away from Meizhou City, Yu San ordered to dismount and walk. Ouyang Xuan's request for this operation was to try not to use force as much as possible, and to create clues to lead suspicion to the Mongols. Although Yu Xing's father and son were unjust, the Thunderbolt army could not be unkind and should try to avoid conflict with the Jiading army. Otherwise, there will be all kinds of harm and no benefit in fighting against the great cause of Mongolia. As a last resort, Ouyang Xuan would never do this kind of "hater hate". To this end, he used the "Firefox" lurking in Meizhou City.

The action team hid the war horse in a small forest two miles outside the city. After leaving someone to guard it, Yu San quietly led people to the city wall. Meizhou is only forty miles away from Pengshan City, which is occupied by the Mongol army, and the defenders are extremely vigilant, but the city wall where the action team goes, and its guarding officers are the inner line of the Perak army. The two sides exchanged the code, so they released the rope to pull Yu San and the others into the city, and led them to the place where the hostages were held. Late at night in early winter, it is the time to fall asleep. The action team had the strategy of the "Firefox" in the city, and did not alarm the people along the way.

With the help of the insider, the action team quietly opened the cell door and successfully rescued the hostages. When taking the hostages outside the city, Yu San ordered people to sprinkle minced meat and cheese along the way, and left behind a Mongolian horse whip. At this time, the Meizhou guards guarding the hostages were still asleep. Before this operation, Dong Hu sent reconnaissance personnel to survey the route of action, and ordered the "Fire Fox" to pull a close relationship with the guards and send honey wine every night. Honey and wine are extremely precious things, and they can be drunk by these big-headed soldiers on weekdays. It's just that they also understand the truth of "nothing to be courteous, either a traitor or a thief", and at first the captain of the guard was also skeptical, but after all, he couldn't resist the temptation and drank some, but he also tasted it lightly. Seeing that he drank nothing, where were his subordinates willing to do it, they snatched up the wine one after another.

The first mead had no peculiar smell, but the next few days were filled with sweat medicine. It was only a small amount at first, and then gradually increased the dosage. When these guards drank it, they fell asleep, just because the honey wine had a good effect on sleep. On the day of the operation, Nei Ying increased the dose of sweat medicine and secretly stuffed a jar of honey wine to the two soldiers on duty. According to the regulations, the soldiers on duty are not allowed to drink, but these two soldiers have long been hungry to death, how can they bear it? Soon after the effects of the sweat pills took effect, the guards fell asleep.

Yu San took the rescued hostages to the grove of Tibetan horses, accompanied by the fire fox "Neiying" of Meizhou City. The people who delivered the honey wine in this operation have been exposed, and the petty officers guarding the city walls will also be held accountable for their negligence, so the plan was drawn up with the idea of bringing them back together. As for their families, they had gone to the Perak military area under various pretexts two days earlier. The action team consisted of one man and two horses, and there were still many empty horses, so they immediately rode their horses together in the direction of Pengshan City. Before leaving, Yu San also ordered two soldiers to go to the city gate to make a move, which caused the alarm bell at the city tower to be full of arrows. The Meizhou defenders, who were awakened, lit the torches again, and saw that there were cavalry under the city shouting Mongolian language and leaving. When Zeng Yong, the current commander of the teaching battalion, joined the Perak army from Wang Dechen's department, he brought with him some of his subordinates who were proficient in Mongolian.

Yu San rode his horse all the way. They will rendezvous with the fleet of sailors led by Huang Dagen by the river ten miles downstream of Pengshan City, and return to Chongqing Mansion City by water. Speaking of this operation, it seems that only Yu Xing leads a team, but there are many support personnel behind the scenes. In addition to the vital intelligence reconnaissance and receiving the internal line, the Xinjin City Navy also dispatched dozens of ships. Among these ships, in addition to logistical ships transporting men and horses, there were more than a dozen reconnaissance ships, as well as various warships including heavy gunboats, light artillery ships, and escort ships, and even a company of sailors and marines. The reason why it took so much effort was to prevent the attack of Pengshan City and the Mongolian army from the direction of Chengdu.
