The convoy escorting supplies was slowly marching on the road back to the Cangnan army camp, and the general surnamed Bai asked Zuo Yin about various herbs from time to time, and seemed to be very interested in it, and Zuo Yin also knew that this middle-aged man surnamed Bai was the capital of the Cangnan Arms Department, leading 20,000 elite Fire Tiger cavalry, but seeing Bai Dutong's studious posture along the way, people who didn't know might think that it was an old apprentice from a pharmacy, and humbly asked the "seniors" for questions here.

Along the way, Zuo Yin felt peculiar to Bai Dutong's curiosity about herbal medicine, but he still answered the general's questions one by one according to what he learned from his grandfather since he was a child, and during the conversation, Bai Dutong also introduced the approximate strength composition of the Cangnan Army to Zuo Yin, who grew up near Qingshan City since he was a child, for example, the Cangnan Army has more than 50,000 permanent troops, more than 5,000 people in the Wind Department, responsible for spying on military intelligence, and more than 5,000 people in the Forest Department, all of whom are carrying out tasks that do not know what stumbling blocks are in the secret, and there are more than 20,000 people in the Fire Department, Responsible for each attack of the alien race, more than 20,000 people in the mountains, there are many craftsmen of all kinds, and there are about 17,000 people who can really fight, mainly responsible for the defense of the passes near the Cangnan Army, and I can listen to Zuo Yin's fascination and yearning all the way.

There is often a drizzle in the spring in southern Xinjiang, fortunately, there is no big impact on the itinerary of the convoy, at most it is slightly moistened on the ground, many veterans and horsemen laugh that the temper of this weather is like a little girl in the south of the Yangtze River, warm and moist, and at the same time gags to tell some meat jokes, when the voice drifts over, Zuo Yin, as a teenager in a mountain city, blushed a lot when he listened, so that Bai Dutong looked at it with interest.

Zuo Yin traveled with the convoy for more than four days, in four days, the general convoy got up early, ate and rested at noon, and continued to rush until dark in the afternoon, under normal circumstances, the soldiers and horsemen also bragged about it together, self-directed under the general trend of the world, talked about what they saw and heard in life, and slept directly, Zuo Yin knew that he was just a teenager in a mountain city, although he also wanted to say hello to others or something, but after all, he was still a little introverted, In addition, Zuo Yin knew the invisible distance between himself and those veterans and grooms, so he did not take the initiative to contact them.

Four days of running and tiring, Zuo Yin swallowed in his stomach, when he went up the mountain to collect medicine, he often spent seven or eight days in the deep mountains and old forests, most of them were dark and damp woods, plus his grandfather knew a little about medicine, and often let him eat some wild fruits and weeds in the mountains, so Zuo Yin's body was much stronger than his peers, and this kind of physical fitness made Bai Du on the side amazed, and seemed to be quite interested.

On the night of the fourth day, the convoy rested on a wide grass, the convoy was stationed in the camp, just after dinner, Bai Dutong found Zuo Yin, carefully inquired about his physical fitness, learned that after Zuo Yin exercised since childhood, General Bai turned his head to the young man who carried the flag all the way: "Zizhan, bring your knife." ”

It turned out that this person who was silent all the way was called Zizhan, Zuo Yin secretly remembered the name of this young man who led the way all the way, and saw Zuo Yin staring at Zizhan, Bai Dutong explained: "Yang Zizhan is my deputy general, and he reached this position at a young age, and there are many powerful young women in the empire who love him. After that, he looked at Zuo Yin with a mocking face, Zuo Yin smiled bitterly in his heart, this Bai Dutong is really "approachable", but because of this, Zuo Yin was full of good feelings for him, and when he looked at Yang Zizhan again, he saw that his face was still silent, and he didn't seem to care about his general's frivolous words.

Yang Zizhan drew a long knife from his waist, the slender blade with a width of three fingers shone silver and fiery red between the moonlight and the bonfire, and there were patterns similar to fish scales on the blade, dotted on the knife, and the whole knife was bent into a special streamline, revealing a simple texture.

What a beautiful knife, Zuo Yin respectfully took the knife with both hands, but in an instant his hand sank, he knew that the weight of this knife was not light, fortunately, it could still be waved, the whole knife was wiped very brightly, and there were many scratches on the blade, obviously it was a knife of a hundred battles, and the handle was wrapped in a clean cloth, obviously Yang Zizhan cherished his saber very much, Zuo Yin couldn't put it down, but he didn't find Zizhan's indifferent look at it.

Bai Dutong saw that Zuo Yin got the knife, and ordered him: "Lift the knife, cut hard to the tree next to it", Zuo Yin didn't understand what he meant, but he still walked to the tree according to his words, his feet were shoulder-width apart, his knees were slightly bent, and then he held the knife with both hands, lifted the knife, and looked at this posture, and many of the soldiers around him had appreciation in their eyes.

Taking a slight breath, Zuo Yin's left foot forward, quickly slashed towards the tree, "click", the knife had already cut into the tree a quarter of a deep, and the instantaneous rebound force came from the handle of the knife, almost shocking Zuo Yin's hand! However, Zuo Yin knew that this was his chance, and Bai Dutong couldn't let him do it for no reason, so Zuo Yin held the handle of the knife until a trace of blood oozed out of the tiger's mouth, and bursts of stinging pain stimulated Zuo Yin's nerves.

"Haha, Zizhan, how is this teenager?" Bai Dutong seemed to have a lot of appreciation for Zuo Yin, but he didn't know why he had to ask Yang Zizhan's opinion.

"He has a stoic temperament, understands herbal medicine, and has a physique that exceeds that of ordinary people of the same age, looking at his steps and techniques just now, he has a little talent in knife skills, and he is a seedling." Yang Zizhan didn't seem to mind Zuo Yin's "torture" of his love knife just now, and calmly made a basic evaluation of Zuo Yin, and the soldiers around him heard this evaluation and looked at Zuo Yin again, and they were no longer secretly jealous of being in the same car with the general all the way with him, but with deep envy. Of course, they knew what it meant to be able to be noticed by the general and Yang Zizhan.

"Whew", Zuo Yin heard the evaluation of Deputy General Zizhan, but didn't say much, but lowered his head and handed the knife back to him with both hands, and saw that Zuo Yin's face did not have a smug look because of Yang Zizhan's praise, and the praise on Bai Dutong's face was even worse, and finally turned into laughter.

"Good, good, good", even saying three good words, Bai Dutong put away his appreciation, and he opened his mouth and said loudly: "On the battlefield, the sword has no eyes." The war is imminent, and I don't know if I can live until the end of the war, so I will pass on my Bai's knife skills, although it is only a knife technique that the entire empire does not enter, but as a beginner, it is still suitable for you, as for following the doctor to collect medicine, there is no conflict, you take medicine for ten years, and practice knives for ten years, but during the period of medicine collection, you have to practice well. Hearing this, Zuo Yin was a little overwhelmed for a moment, and was shocked by Bai Dutong's sudden declaration of accepting disciples, but he quickly came to his senses, and immediately knelt down to worship Bai Dutong as when they first met, but this time it was on his knees.

"Apprentice, knock on Master." Zuo Yin bowed deeply to Bai Dutong, and his heart was simple and grateful and excited.

"Your name is Zuo Yin, from today on, you are still a trainee pharmacist in the fire department's physician battalion according to your original identity, helping the doctors to collect medicine and make medicines, but you will have a place in my personal guard battalion, two identities, one change every ten years, but no matter when, you have to get up early every day to practice knives." Bai Du's words have already finalized Zuo Yin's life in the Cangnan Army. After a pause, Bai Dutong spoke again: "By the way, your master and I are called Bai Changzhi, and remember, remember to bandage the wound of the tiger's mouth." After saying that, Bai Changzhi showed a caring smile.
