Wang Gang, who looked at the 1400 gold coins, fell into a speechless position for a long time, originally thought that he had more than 100 million copper wires, but now it seems that the most money-burning is the war machine, and I don't know what price the war machine behind it will sell one by one.

However, seeing the female general again also made Wang Gang's frustrated mood suddenly feel a lot better.

Hero Yao Bi (female)

Armed forces 72 commanders 27 intelligence 96 politics 33 charisma 93

Stunt: Guidance, reduce R&D costs, and improve production efficiency.

With the emergence of a woman's figure, it quickly attracted the attention of several people, the woman looked dignified, smiled sweetly, and was slightly taller than the average woman. The short body bowed to Wang Gang.

"Yao Bi, I've seen the general"

Wang Gang originally wanted to exchange for another assassin-type talent like Hua Yu, who could be sent to protect Zhang Yue'er, but he didn't expect that he was an intellectual hero, did he want to stay by his side as a staff member, but just thinking about it, now is not the time to enjoy, and the development of the state is the first priority.

"Your stunt is a bit special, can you invent something new, such as guns, cars, etc.," Wang Gang asked with some curiosity.

"The general laughed, the little girl can't be developed, it's just auxiliary production, as for the guns and cars, the general doesn't think about it, and it's a waste of resources, if you want to develop your power, the early formation of internal circulation is the right way, relying on the exploitation of resources, it can't last long, and there will always be a time when resources are exhausted" Yao Bi covered her mouth and chuckled twice.

"What does inner circulation mean" Fan Chong had also asked a similar question before, Wang Gang didn't care too much, and today he heard Yao Bi talk about it, and couldn't help asking.

"To put it simply, the inner circulation depends on the exchange level, and the things that are made are sold to the exchange device to make a profit, just like buying ore and selling weapons."

"Isn't that a processing plant" Wang Gang suddenly understood, he could still play like this.

"It can also be understood in this way, but if the scientific and technological civilization is too low, the profit is relatively small, for example, a unit of grain is 30,000, and it can be sold for 35,000 when processed into military food, and this 5,000 is the profit, ten people can make a unit of military food in one day, minus the consumption of the people, and a unit of military food can probably earn 1,000 copper coins" Yao Bi carefully explained to Wang Gang.

Wang Gang was speechless for a while when he heard this, it was too difficult to make money.

"So how can we make money quickly, for example, we buy some steel and build some planes to sell. Isn't it possible to make a lot of money?"

"Theoretically, yes, provided that the system does not sell anything beyond the current civilization, which is why the system does not have thermal weapons, and the food exchanged by the system cannot be grown in the current civilization. If you want to make money, in addition to having a lot of resources, you also have to improve the current civilization level, which is impossible to do for a while" Yao Bi finished speaking, looking at Wang Gang with a regretful expression.

Wang Gang was speechless for a while, last time he gave Liu Kuan a lot of sweet potatoes in Luoyang and asked him to plant them, but there was no news. I think Liu Kuan didn't send it out, and he wasn't embarrassed to talk to him again.

"Then is there any way to make money quickly?" asked Wang Gang reluctantly.

"If you exchange for more special talents, if you have an advantage in production, you can make money even if the civilization level is not high"

"Okay then, you rest next to you first, I'll take a look," Wang Gang sighed.

Since the red rabbit horse is here, don't let it go, and the vector array illustrated book has also been bought. Handed it to Chu Yu, who had been silent, and said.

"This is for you, I remember that the commander is more than 85 and can use the formation"

Chu Yu took it in his hand and looked at it, handed it back to Wang Gang and said.

"It's a cavalry formation, I don't need it"

Wang Gang was puzzled for a while, he didn't pay attention to it, he only saw a arrow, thought it was used by archers, and opened the illustrated book to look at it.

Sagittal Formation Illustrated Book: A special guide for cavalry, which increases the breakthrough ability of cavalry. Commander-in-chief 85 and above can learn.

Wang Gang now understands that no wonder several of them don't have a formation, it turns out that the formation is learned by the illustrated book, and it also costs 50 gold coins, since Chu Yu can't use it, he can only put it away first.

Remnants of the Chronicles: A part of the Chronicles, collect five pieces to craft. Currently owns 1/5. Has +1 Intelligence on this Leaf Stump.

This is a bit of a pitfall, when will it be collected. Wang Gang casually handed over the remnant leaves to Yao Bi, it would be good to add a little intelligence.

Yao Bi shook his head and said.

"If this historical record can be synthesized, it is very powerful. It's a bit of a waste for me to use, Hao Meng is more suitable for this kind of thing."

Wang Gang looked at Hao Meng, and sure enough, he was as calm as water, but now his face was anxious.

"Hao Meng, everyone is their own person, if you have something to say in the future, just say it, since you are suitable, you can speak directly" After Wang Gang finished speaking, he handed the remnants of the historical record to Hao Meng.

"General Xie," Hao Meng bowed again.

Wang Gang stayed on the red butterfly, and was slightly surprised in his heart.

Red Butterfly: Women's jewelry. Increases affinity, charisma +2.

The reason for the surprise is that items are generally plus 1, and I have never seen the effect of +2. If you bring a few of them, won't it go to heaven? Wang Gang looked carefully at a hairpin-like hair ornament in his hand, which was a little different from an ordinary hairpin, and there was a pendant at the tail of the hairpin, on which there was a butterfly fluttering its wings ready to fly, and with the swing of the hairpin, it spread its wings lightly.

Wang Gang looked at Yao Bi, who was a little envious, and said with some embarrassment.

"This hairpin is going to be given to Zhang Yue'er, and I will buy it for you when I meet it next time."

The general laughed, I just thought it was beautiful and not for me. And this is not a simple hairpin, it is a step shake, and it is generally worn by dignitaries and wives."

After listening to Yao Bi's explanation, Wang just now knew that this thing still had its own name, no wonder it was a little different from the ordinary hairpin, and put away the red butterfly step carefully.

Seeing the five strong bows below, Xiang Chu Yu asked.

"Do you want these five bows, the last time you compared arrows, it seems that this kind of longbow was used"

"Since you have encountered it, the general might as well buy more and give it to the general in the future, and also have a lot of self-defense weapons."

Chu Yu looked at the longbow on the screen and spoke.

"Can't the soldiers use it?"

"The use of bows and arrows by soldiers is related to their own strength, such as one-star archers, who generally use half-dan horn bows, two-star longbows, and three-star longbows. As for the five-dan bow, generally only the military generals can pull it out. Some special soldiers can also be pulled away, and even four-star archers can also be pulled away," Chu Yu explained to Wang Gang.

"Four-star archers, isn't it that ordinary soldiers can only be promoted to three-star"

This Wang Gang remembered very well that only special troops could be promoted to four stars.

"Stunt Bow God, you can raise the archer to four stars, but this kind of opportunity is unavoidable, unless you have experienced a life-and-death battle, you can break through the limit, and you can use these five strong bows"
