"Extract spirit veins?" Tang Rong said immediately after hearing Li Xian's idea, "Master, spirit veins cannot be extracted. Spiritual veins are attached to jade and cannot exist independently. In addition, if you are talking about silk threads, perhaps some silk threads of monsters can satisfy you. For example, the silk threads of heavenly silkworms and jade silkworms, such as the silk threads of human-faced spiders. In addition, it is said that there is a kind of sea soul silk in the sea, which also has this ability."
"Damn, what are you waiting for? Buy it now!" Li Xian jumped up when he heard it. The role of wires in industry is equivalent to the role of blood vessels in humans. They are indispensable! If there are wires, let alone shrinking the engine to one foot, even shrinking it to the size of a fingernail is enough!
"This..." Tang Rong sighed regretfully, "Master, there are very few of these things, and the quality varies, some are good and some are bad. Most importantly, the price... is very expensive. If you want to buy these spiritual materials, you can't trade with gold, you must trade with spiritual stones."
Crash...
A basin of ice water was poured on Li Xian's head.
"I knew that things in this world would not be that simple." Li Xian sighed, and finally went to ask Xu Ren for advice; this time Li Xian really realized the importance of a counselor.
"What's so difficult about this!" Xu Ren smiled nonchalantly, "Master, for those demon silkworms and spiders, they have a lot of these silk threads, and they don't need them in the cave. What they like most is the items from the human world. Master, you can send a caravan with mirrors, lanterns, cloth, etc. to trade directly with these demon beasts. They are happy to exchange. The so-called expensive is just because it is rare and the merchants raise the price. But this matter will have to wait, we have to act carefully and not let everyone know."
"Then let's send someone now." Li Xian couldn't wait any longer.
"Master, don't be impatient. You can't get anything done in a hurry. Besides, you should develop a large number of looms now, and then use a large amount of cloth to contact more people and form your own network. This is the most correct way to do it."
"Oh, sir, you're right. I was too impatient." Li Xian immediately adopted Xu Ren's suggestion and asked the research department to temporarily slow down the pace of engine miniaturization and turn to research on how to increase engine output power. The three-foot-long engine was barely acceptable.
"Master, it's time to go back to Wuyang City. Your chance should be coming soon."
"What chance?"
"An opportunity to leave Wuyang City openly! For more details, you will know when you return." Xu Ren kept it a secret.
"All right."
The two of them got on the carriage and leisurely returned to Wuyang City.
Li Xian's status in Wuyang City is more like a hostage, and he cannot leave Wuyang City at will. In addition, Wuyang City is not a good place to develop. There are too many officials here, and the Great Xia Kingdom is already in turmoil. It is necessary to leave the capital - the building is about to collapse, so of course you have to run far away.
As soon as he approached Wuyang City, Li Xian was stunned. After only a few days' absence, the walls of Wuyang City were already hung with searchlights that had only recently started to be produced; and now there were many Foundation Establishment cultivators flying in the air to install them.
