In the Qianyang General Army's Mansion, Pan Yu and Yi Tianxing talked and walked towards the study: "Yi Ergongzi really lives up to his reputation, Shao Qianchuan and Tong Wangyuan join forces, and there are no more than a dozen people in this Qianyang City, I can't imagine that you can easily defeat them." ”

Yi Tianxing said casually: "Where is it? I almost lost." ”

The gold and silver shuangji who followed behind them seemed to be unable to stand the polite words of Pan and Yi, and both said, "Can you two not be so fake?"

Pan Yu turned around, squatted in front of them, and said with a smile: "It's not fake, this is communication, although these words don't mean much, but they can narrow the distance between people." If it were your eldest brother, fourth cousin, and seventh cousin who came to my house, everyone would have a lifelong friendship, so naturally there was no need to be so polite, but it was not appropriate for me to meet your little brother for the first time, so I needed to start with such nonsense. ”

Yin Ji said: "The little brother is sincere, so it's not uncommon for you to be polite to him." Said and smiled at Yi Tianxing: "You're right?"

Yi Tianxing rolled his eyes: "It's not fake that you slapped my ass?"

Yinji grimaced: "I'm afraid of you!"

Yi Tianxing also knew that when he returned home, he was covered by his mother, and there was nothing he could do about these two little devils, they were simply fearless, but when he thought of his helplessness in educating these two little girls, he couldn't help but burst into flames, and said viciously: "There is always a journey home." ”

Jin Ji grabbed the hem of Yunni's clothes in horror, hid behind Yunni, and said timidly: "It's none of my business, I haven't said anything." ”

Although she had dealt with Jin Yin Shuangji many times, Yun Ni had long known the little tricks of the two of them pretending to be pitiful in front of her face and making yīn tricks behind her back, so she still couldn't help but protect Jin Ji: "Don't be afraid, don't be afraid, Yi Er Gongzi is playing with you." ”

Yinji pouted angrily and said, "No, my little brother often beats us." ”

Yi Tianxing's forehead was beating, and he held back a sentence for a while: "Your golden-winged purple jade cicada is gone." ”

Hearing this, Yinji sat on the ground, rubbed her eyes and cried: "You bully people! I didn't lie!"

Seeing this, Yunni hurriedly stepped forward to reassure: "Yinji, don't cry, your brother won't buy it for you, but my sister will buy it for you." ”

Yinji cried even louder: "It's useless, you can't buy it!

The more Yun Ni persuaded her, the more Yin Ji cried miserably, and she refused to get up on the ground, and sat down again as soon as she dragged it up, and finally Pan Yu couldn't help it, turned her head and asked, "Second Master Yi, what is this golden-winged purple jade cicada?"

The corners of Yi Tianxing's mouth moved slightly, and he said in secret: "It's just a kind of cicada, it's just very beautiful, it's useless, so it's used to tease children." ”

Pan Yu continued to ask, "Why haven't I heard of it?"

Yi Tianxing said: "The area where this cicada lives is very special, the number is small, and it is useless, except for people like me who like to study strange insects and foreign objects, not many people know about it, let alone catch it." ”

Pan Yu sighed secretly, the gold and silver concubines were drowned like this, but it was not Gu Lingshu's fault, the two of them looked pink and jade, and they were smart and clever, and anyone who saw it liked it from the bottom of their hearts, plus the relationship between the family, which of the black and white characters in Qianyang was not their elders? The rampant xìng ge, take it as an example, he is sure that Yun Ni is sad and sad in his heart, and even has some grievances against Yi Tianxing, but everyone is an adult, considering the necessity of befriending Yi Tianxing, she did not stand up for Yin Ji, and what he asked just now was also an idea, if you can buy it, you can buy it, if you can't buy it, you will send someone to capture it, and you must follow Yin Ji's wishes.

However, from Yi Tianxing's reply, Pan Yu also saw Yi Tianxing's thoughts, he just wanted to use these gadgets to control the gold and silver double concubines, since the problem could not be solved, then tempt them to benefit, so Yi Tianxing did not say where to catch the golden-winged purple jade cicada, and he was not good at continuing to ask.

Pan Yu spread her hands helplessly: "Sister Ni, take good care of the gold and silver concubines, and I will go to the study with Yi Er Gongzi first." ”

Yunni hugged Yinji and nodded with a smile: "You go first, here I am." ”

Pan Yu smiled bitterly and walked towards the study with Yi Tianxing.

Without the gold and silver double concubines, Pan and Yi walked like the wind, and within a few moments they had already entered the study and sat down.

Pan Yu's study is not big, only about Zhang Xu, except for a table and a chair, there are only two bookcases on the opposite and left, which are full of books, and there is nothing else, even the furnishings in the ordinary study, such as celebrity calligraphy and paintings, there is no one.

The bookcase on the left is full of military books, which look very messy, apparently used by the owner often and put them on hold. The bookcase across from the desk was much neater, with books in order and spotless, but no sign of flipping through them.

"Sit. Pan Yu waved his hand.

Yi Tianxing glanced at a chair in the only room: "I'll just stand." ”

Pan Yuwan smiled: "I'm really sorry, I'm used to staying alone in the study and thinking about things, and I never planned to receive guests here, so I ......"

Yi Tianxing waved his hand and said: "Although we met for the first time, we don't have to be too angry between us. My brother believes in you, and you are my friend. ”

Pan Yu laughed and said, "That's right, we really don't need to be too angry. Then he came to the neatly stacked bookcase, stretched out his hand and inserted it between the two books in the second compartment, and moved it slightly, and a low sound came from the ground of the study.

Yi Tianxing watched quietly, and after a while, a hole opened in the floor of the study, and a diagonal step stretched downward, making a bend, making him kang to a deep point.

Pan Yu said in a low voice: "Follow me." As he spoke, he led the way and walked into the passage.

Yi Tianxing went down, only to see that on both sides of the passage, there was a night pearl every other meter, emitting a quiet and cold cold light, although it was not a radiant four, but it was enough to illuminate the future.

Pan Yu pressed the third night pearl on the wall, and the passage on the top slowly closed, and the light in the passage suddenly dimmed, but then the light of the night pearl was a little grander.

Yi Tianxing didn't speak, followed Pan Yu all the way down, turned five corners, and the end of the steps suddenly opened up, revealing a basement that was three feet high and covered in acres.

Yi Tianxing glanced at it and found that this basement was in the shape of a gossip, except for the entrances and exits, it was divided into seven rooms, and the first room on the right hand had five rows of bookshelves, which were densely packed with all kinds of books, of which martial arts were the mainstay, occupying more than four rows, and the rest were some books related to formations, geography, ordnance, and medicine.

The second room on the right hand side was surrounded by medicine cabinets on three sides, and a long table was placed in the middle, although it was now empty, but it was overflowing with the fragrance of medicine, apparently used for dispensing medicine. Yi Tianxing took a deep breath, and then smiled knowingly, the smell of medicine on this platform is messy, but the left and right are just the tuning of Jinchuang Medicine and Xingjun Pill, which should be specially used to improve military Chinese medicine prescriptions.

The third room on the right hand was like a shooting range, and the depth of the house was the longest of all houses, reaching two hundred meters away, and there were some arrow targets at the end, and the doorway was blocked by a platform with some bows and crossbows on it.

In the room opposite the entrance was an iron-making stove, the fire had been extinguished, and next to it were various weapons.

The third room on the left hand is also a pharmacy, the pungent smell of medicine can be smelled at the entrance, as a master of poison Dao, Yi Tianxing naturally knows what it is, compared to the pharmacy in the second room on the right hand, this place with poison is obviously much more high-end, and there are quite a few poisons that even he has some scruples.

The door of the second room on the left hand was closed, and I saw a trace of white cold air seeping out of the crack in the door, and I didn't know what was inside, it was so cold.

The first room on the left hand is the reception room, which is not only equipped with tables and chairs, but also the only room with people. When the two maids, who were about seventeen or eighteen years old, saw Pan and Yi coming down, they immediately took action, one waited for Pan Yu and Yi Tianxing to take their seats, and the other served tea in time.

Pan Yu waved her hand away from the maid: "Second Master Yi, I think you have also seen it, this is my private research room, how do you feel?"

Yi Tianxing said: "The purpose is very clear, it is used in the battle array. ”

Pan Yu's face darkened, and he smiled bitterly: "Isn't this a good grade?"

Yi Tianxing said: "It has nothing to do with grade, the rivers and lakes and the army are two completely different worlds, you can play a game in the rivers and lakes, make it beautiful, make it strange, and make it unique, but the army is different, and the requirements of the army are standard, unification, mass production, and stability." Therefore, a kind of thing is researched to be used in military conquest and for fighting in rivers and lakes, which is clear at a glance. ”

Pan Yu said: "In that case, how about giving some advice?"

Yi Tianxing said: "The most important thing about military drugs is not how good the formula is, but the supply of raw materials is guaranteed, I am not familiar with the drugs produced in Yizhou, you make a list, I will give you a few formulas." As for the poison you refined, it went astray, and the military supplies should not only have a stable supply of raw materials, but also try to keep the price as low as possible, although the ghost beard grass is not rare, but it is also used for people in the rivers and lakes, used to make standard weapons, and if you quench the poison for three thousand weapons, you can use up all the stocks in this world, as for the large-scale use of the seven-core lotus, it is even more outrageous, first, this thing is not produced in Shenzhou, once the situation is chaotic, you can't guarantee the supply at all, second, the price of the seven-core lotus is too expensive, if I remember correctly, one flower will cost two hundred taels of silver, right? Used to quench the poison of standard weapons...... In fact, the army doesn't need much skill to use poisons, don't complicate things yourself, you give me a list of poisons produced in Yizhou, indicate the output and price, and I will help you prepare the prescription. ”

Pan Yu smiled: "Yi Er Gongzi is willing to take action in person, I can't ask for it, hehe!"

Yi Tianxing said: "You don't have to be polite. However, I can't help in the development of new types of weapons. ”

Pan Yu said: "The improvement of weapons is a long-term and unremitting process, not for a while, but poison can quickly increase combat effectiveness. ”

"That's right. Yi Tianxing immediately remembered that there was originally a gold and silver double concubine with him: "By the way, you just planned to bring those two girls down?"

Pan Yu hurriedly shook his head: "How is that possible? They are always too young, and they don't know how to distinguish between them, so they are not suitable to know this." ”

Seeing the suspicion in Yi Tianxing's eyes, Pan Yu added with a smile: "Do you think they will stay in my study? They can't be idle at all, and they will run out to play by themselves after a while." ”

Yi Tianxing sighed: "I said." But Brother Pan showed me this laboratory, it's not just as simple as asking me to help, right?"

Pan Yu's expression was solemn: "Wait." After that, he stood up, walked to the next door, and opened the door, Yi Tianxing sat still, feeling that the temperature of the entire basement had plummeted.

Pan Yu's voice came from next door: "Some things must be refrigerated, so I built a freezer." ”

As he spoke, Pan Yu had already walked back, holding two boxes in his hands, one jade and one wooden, and gently placed them on the table in front of Yi Tianxing.

Yi Tianxing saw Pan Yu's cautious appearance, and his heart also paid attention to it, holding the wooden box with both hands, and with a slight pick of his thumb, a fragrance came to his face, and the box was a string of sè vermilion, shaped like a flying sparrow, and a spike of seven flowers.

Yi Tianxing's eyes lit up: "Vermilion Bird Flower!" closed down like lightning and opened the jade box, which contained two crystal bottles, one red and one green.

Yi Tianxing gently twisted the crystal bottle, the bottle was only the thickness of the index finger, and the cylindrical appearance looked like two test tubes, which contained red sè and green sè liquids respectively, the bottle was not large, and the amount of liquid was less, only accounting for a thin layer at the bottom of the bottle, and it was estimated that there were only one or two drops poured out.

The red sè liquid appears viscous and heavy, between the movement of the bottle, it firmly adheres to the bottom like a gel, and the green sè liquid is crystal clear, and from time to time a strong light bursts out of the shè, spreading out through the surface of the bottle, illuminating the basement with a piece of turquoise.

There was no need to distinguish anymore, Yi Tianxing was excited in his heart, stuffed the bottle back into the jade box, and then bowed to Pan Yu: "Brother Pan has a heart." ”

Pan Yu looked compassionate: "Yi Fenghan is not only your brother, but also my brother. ”

Yi Tianxing said: "I'm ashamed, I'm not as good as you as a big brother about him." ”

Pan Yu shook his head and said: "You are alone, you can't compare to a large group of people under me, not to mention, this abyss demon lizard blood and immortal tree sap were all purchased by your fourth cousin from Jingzhou, and I can't take credit for it." ”

Yi Tianxing said: "Vermilion flowers are not so easy to get. ”

Pan Yu sighed: "Yes, in order to get this Vermilion Bird Flower, my brother here has caused some trouble, and it has not been settled yet." ”

Yi Tianxing raised his eyebrows: "What's the matter?"
