A series of loud noises woke Su San'er up, and the strong smell of fire and dust made him sneeze first, and then cough violently. He struggled to open a slit in his blood-soaked eyes, and found himself still lying on the horse's back, except that the Mongolian horse was not running, but had fallen to the ground.

Su San'er is Chinese New Year's Eve years old this year, is a scout in the army of Yu Xing, the prefect of Jiading, since he joined the army at the age of 14, he has experienced more than 100 battles, and has been promoted to chief. This time, Yu Xing assisted Chengdu on the order of Pu Xue, and not all of them were good fighters, he just picked some elite people to go to Chengdu, and Su San'er was one of them. This morning, he was ordered to take Bensh out of the camp to spy on the Mongol army, but he was unexpectedly discovered by the Mongol rangers. There was a shortage of horses in the Song army, Su San'er was infantry, and the Mongolian cavalry that pursued them was also ten. Although the number of people on both sides is equal, Su San'er knows very well in his heart that there is absolutely no unity on this plain, and only by escaping can he survive.

Just how can two legs run over four legs? In a panic, Su San'er's scout team hid in a small wood, and tried to lure the Mongols into the woods. Unexpectedly, the Mongols did not dismount at all, but directly set fire to the forest. It was early spring, when the climate was dry, and the wind-fueled fire turned into a prairie fire for a while. Under the thick smoke of the fire, they fled from the grove in a hurry, but they did not escape the Mongols who followed them, and all nine except Su San'er died tragically under scimitars, bows and arrows, and horses' hooves. Su San'er knew that it was not luck that he was not killed, but because the Mongols wanted to catch him alive. Thinking of the cruel methods of the Mongols to obtain confession information, Su San'er shuddered. In order not to be captured, he also had suicidal thoughts. It was only the desire to survive that made him hesitate slightly, and then he was tied up by the thrown lasso, and was firmly tied to the horse by the Mongolian cavalry, ready to be brought back to the camp for torture.

A whispered conversation came from the front shrouded in smoke and dust, and he struggled to get up but couldn't move—his body still firmly tied to the saddle. As the voices drew closer, several men in monk's robes walked up to them in the fading smoke and dust, untied the ropes and lifted him up again. Bypassing the corpses of the Mongol cavalry on the road, he was brought to a sleek, black-faced man in front of him.

"Thank you for the grace of the strong man for saving his life", Su San'er, who was untied, cheered up and thanked the black-faced man. "The Mongol Tartars invaded my homeland, burned, looted and killed indiscriminately, although they were monks, we also swore not to share the sky with these orcs." The black-faced man replied. Su San'er believed the black-faced man's words, because just now he saw these people in monk robes mending the corpses on the ground one by one, for fear that the Mongols would not die thoroughly.

Although he didn't quite believe that they were monks from the Huacheng Temple in the mountains of Yongkang County, but these people were enemies of the Mongols and saved their lives, Su San'er immediately let down his guard and told his situation as it was. The black-faced man calls himself Cheng She, and he looks bold everywhere in his speech and demeanor, which is quite in line with Su San'er's appetite. This Cheng She is actually the commander of the anti-espionage company under Dong Hu, but the reason for the mission can only be pretended to be a monk, but the name is true. Cheng He asked Su San'er about the situation in the army, and he also answered them one by one, and the two sides hated each other for a while.

Seeing that Su San'er had an arrow wound on his arm, Cheng Tong first cleaned the wound with water, then took off the gourd next to his waist and poured out the liquor to clean it and bandage it, and confidently said that his injury did not reach his muscles and bones, and it would heal in less than a month. Cheng She's operation made Su San'er half surprised and half regretful. Surprisingly, the injuries that weighed heavily on my heart finally don't have to worry. In this era of backward medical technology, even if not fatal injuries, wounds like Su San'er were often infected by germs in the feces, ranging from crippled arms to high fever in severe cases. It's a pity that such a precious elixir jade liquid has no entrance, which is really a pity. Just as the gourd stopper was unplugged, the fragrance burrowed into Su San'er's nose, making his throat move, and when Cheng She dipped the wound in strong wine, he couldn't help but hum. In fact, for Su San'er, who has been in battle for a long time, the sting of the liquor is nothing at all, he just hums to hide the greed in his heart.

As for why such a precious liquor was used to clean the wound, Cheng She only said that the use of liquor to deal with the redness and swelling of the wound was invented by Brother Xuan of Perak, and he learned it when he got closer to Huacheng Temple. In fact, it's no wonder that Cheng She is vague, when Ouyang Xuan gave a lecture in the night school, he talked about the principle of use at first, but most people couldn't understand it, for example, this theory of 75% alcohol disinfection, only Du Daquan, who has been running medicine for generations, understood it, a few people seemed to understand it, and most people listened to it in a fog. In view of this situation, Ouyang Xuan's next lectures, except for the research institute, only talked about operation and not theory. The Thunderbolt army is very supportive of this, anyway, according to them: it doesn't matter why you do it, what Brother Xuan said is right, just do it.

While Cheng She and Su San'er were talking, the rest of the people were busy, some were collecting weapons and peeling off the leather clothes on the corpses of the Mongols, some were slaughtering wounded horses that could not walk, and some were busy peeling horses and removing meat, the technique was very skillful, it seemed that it was not the first time to do this. Cheng She saw that Su San'er was almost recovering, so he sent two people who could ride horses to send Su San'er back to the Song army camp. It is about 20 miles away from Chengdu City, and 15 miles away from the Song army camp outside the south gate. According to Su San'er, during this period of time, due to the fierce offensive of the Song army, there were actually very few rangers of the Mongolian army out of the city to reconnoitre, and they were raided by the Mongolian cavalry because of their carelessness, which was similar to the situation that Cheng She had mastered. According to the law of the activities of the Mongolian army that he had mastered recently, Cheng He predicted that there would be no more Mongolian rangers in this area today, so he dared to take the risk of sending Su San'er back to the Song army camp.

The two Thunderbolt soldiers drove a horse, one of them rode with Su San'er, and the other horse was also carrying leather clothes, leather armor, bows and arrows, horse meat and other trophies, which were all given to Su San'er. In addition, Su San'er also carried Zhang Thunderbolt's leaflet in his arms. Su San'er was illiterate, and although he had heard Cheng She talk about the content on the leaflet, he was still ready to take it back and ask the literate soldiers to read it again.

The three of them talked while riding, although Su San'er understood that the two were by no means ordinary monks, but they were not easy to break. When asked how to completely annihilate this Mongolian ten-man team, the two Thunderbolt soldiers first looked left to talk about it, and then they really couldn't prevaricate, only to say that the musket they were holding was an iron hollow ring stick from the far west, which was a very powerful magic weapon, and as for the grenade in the waist, it was said that it was a sky-shaking thunder given by the Thunderbolt Army, and it was these two things that combined with Buddhism to destroy the Mongolian cavalry in an instant.

To say that the two people who sent Su San'er back to the camp only knew how to ride horses, although they were not skilled in equestrianism, they were much faster than walking. After a short time, the three of them walked to a small forest where they could see the outside of the Song army's camp, and the two stopped talking and said goodbye. Su San'er dismounted and walked straight to the camp, while the two Thunderbolt soldiers also rode back to their lives.
