"By the way, although we can now refine high - purity spirit stones, these spirit stones of different sizes can't be made into the bullets you want, right?" Chen Tianyi asked.
"Well, it's easy. We just need to make a mold first, then make metal casings of the same size according to the mold. Finally, grind these high - purity spirit stones into powder, stuff them into the bullets and seal the openings." Hu Ke'er said in one breath.
Making bullets was so easy for Hu Ke'er that she could do it with her eyes closed. It was a basic skill for her, but Chen Tianyi was left a bit dazed when he heard it.
"Anyway, it's very simple. But senior brother, let's quickly refine those obtained primordial stones into spirit stones. We'll definitely need them later!"
"Okay!" Hearing Hu Ke'er's words, Chen Tianyi quickly started refining the spirit stones, while Hu Ke'er took out a dagger and started drawing the blueprint on the wall.
"By the way, senior brother, next time reserve this cultivation room we've used. I don't want others to see these things."
It was somehow a coincidence that they were in the same cultivation room as last time.
"Well, actually this cultivation room belongs to the old master. Each disciple will get their own cultivation room when they reach a certain level, and this one is the old master's own cultivation room."
"Oh, I see!" Hearing Chen Tianyi's words, Hu Ke'er nodded.
"After senior brother finishes this, let's make a mold according to this blueprint and then mass - produce the bullets!"
"Well, about this..." Chen Tianyi gave an embarrassed smile.
"Actually, the ordinary metals you need to make bullets are considered waste materials on Mount Longhu. They're only used in small amounts for house repairs on the mountain, so there isn't enough metal on the mountain to make bullets for you."
"Eh?" Hearing Chen Tianyi's words, Hu Ke'er was stunned for a moment.
"There are quite a few special metals, but they all seem to have special properties and aren't suitable for making the bullets you mentioned. And although I can make the mold and bullets, it'll be faster if we find a few blacksmiths to help."
"Makes sense! But are there blacksmiths on Mount Longhu?" Hu Ke'er asked softly.
"No..." Chen Tianyi shook his head and answered truthfully.
"What should we do then?"
"Maybe we need to go down the mountain. There are many metals and blacksmiths you need in the secular world. We can just ask them to make the weapons for you then!"
"Go down the mountain?" Hearing Chen Tianyi's words, Hu Ke'er exclaimed in surprise.
"Senior brother, you're going to take me down the mountain?!"
"If we want to make the bullets, there's no other way. Let's go after I finish refining these primordial stones."
"Okay!" Hu Ke'er quickly agreed.
Hu Ke'er had been in this world for a few days, but she had always been staying on Mount Longhu. Her understanding of the world view might still be a bit one - sided. As the saying goes, traveling a thousand miles is better than reading a thousand books. How could Hu Ke'er give up this chance to have a look around?
"Hey, I didn't expect you to be so happy, junior sister!" Seeing Hu Ke'er's happy face, Chen Tianyi gave a bitter smile.
"What's wrong, senior brother? Don't you like going down the mountain? Isn't the secular world fun at all?"
"It's not very interesting. Compared with the mountain, the secular world is more complicated. At least on the mountain, you know where the guns and swords aimed at you are coming from."
As he said this, Chen Tianyi suddenly showed an extremely sad expression.
"Senior brother, are you okay?" Seeing Chen Tianyi's expression, Hu Ke'er's heart suddenly tightened for no reason, and she felt a bit of pity.
"..." Chen Tianyi didn't answer. He just shook his head on his own, and his hand never stopped refining the spirit stones.
"Junior sister, don't think too much. I'll take you down the mountain after I finish refining these spirit stones. You first finish drawing the blueprint. I'll copy it later and show it to a blacksmith."
"Okay~" Hearing Chen Tianyi's words, Hu Ke'er quickly nodded vigorously.
Since senior brother didn't want to talk more, she naturally shouldn't ask more. If she kept asking him about things he didn't want to talk about, he might hate her, right?
For some reason, just thinking about being hated by Chen Tianyi, Hu Ke'er's heart tightened again.
"What's wrong with me? Could I have some strange illness?"
"Junior sister, what's wrong with you? Are you not feeling well?" Chen Tianyi seemed to hear Hu Ke'er's whisper and quickly leaned over to ask softly.
"Um, I'm fine! Senior brother, don't get so close to me. You're disturbing me while I'm drawing the blueprint!" Hu Ke'er felt Chen Tianyi's strong masculine aura and instantly blushed. Then she quickly turned sideways to keep a distance from him.
"Okay, I got it..." Hearing Hu Ke'er's words, Chen Tianyi quickly turned around and then continued refining the spirit stones on his own. After a while, Chen Tianyi finally refined all the previous primordial stones into fine spirit stone crystals and collected them one by one. On the other hand, Hu Ke'er naturally didn't slack off. Although she was a bit absent - minded at first, after Chen Tianyi kept a distance from her, she successfully focused on the blueprint and copied it onto a silk handkerchief.
"I'm done~ How about you, junior sister?"
"I've been done for a while." Hearing Chen Tianyi calling her, Hu Ke'er quickly handed the blueprint she had drawn to Chen Tianyi.
"Just follow the blueprint on it."
"Okay." Chen Tianyi nodded and then put the blueprint and the refined spirit stones into his sleeve.
"Then we're going down the mountain soon. Junior sister, you should prepare first."
"Prepare for what?" Hearing Chen Tianyi's words, Hu Ke'er asked in confusion.
"Well... since you're already a member of Mount Longhu, junior sister, why don't you change your strange clothes into a Taoist robe first?" As he said this, Chen Tianyi took out a Taoist robe from his sleeve.
"Okay." Hu Ke'er took the Taoist robe and looked at Chen Tianyi, while Chen Tianyi also stared at Hu Ke'er with wide eyes.
"Um, senior brother, could you go out first? I need to change my clothes!"
"Oh, I know the principle of men and women not touching each other. I just didn't think of it for a moment. My bad, my bad. I'll go out and take some pills to replenish the spiritual energy I just consumed. Then we'll leave after you change your clothes."
"Okay." Seeing Hu Ke'er nodding in agreement, Chen Tianyi quickly walked out of the cultivation room.
"Phew~ It's really strange. I don't have a fever, so why is my heart beating so fast?" Hu Ke'er touched her forehead and said.
"... Could I have some strange illness?"
