"Senior Brother, we..."
"Shh—"
As soon as they stepped out of the stone chamber where the spirit stones were refined, Hu Ke'er looked extremely excited. However, at this moment, Chen Tianyi made a gesture for silence.
"Junior Sister, let's find a quiet place to talk first."
After saying that, Chen Tianyi summoned his flying sword and took Hu Ke'er to the cultivation room where they had initially made the flintlock guns and flamethrowers.
"Senior Brother, why didn't you let me talk just now?"
Hu Ke'er frowned and asked in confusion.
"You don't have any cultivation base, so you can't feel it. Just now, I always had the feeling that something was following me. There might be a tail."
"Ah—"
Hearing Chen Tianyi's words, Hu Ke'er was also startled.
"Really? What about now?"
"It's okay. The formations here are quite powerful, and these rooms are all used for cultivation and breakthroughs. No one can follow us here without being discovered!"
Chen Tianyi said softly.
"Alright, since we've shaken off the tail, Junior Sister, you can tell me how you discovered that there were spirit stones under those milky - white bricks."
"It's not that difficult. Actually, it's a very simple reason. The origin stones actually contain quite a lot of spiritual energy. It's just that the refining temperature you guys used was too high, causing a large part of it to turn into gas. And during the refining process, due to the influence of heat, the density of the spiritual energy is relatively low. As a result, the spiritual energy naturally rises slowly. When these gases with spiritual energy molecules touch the cooler milky - white bricks at the top, they will slowly attach themselves. After years and years, they will stay in the gaps inside the bricks."
"Uh—"
Hearing Hu Ke'er's words, Chen Tianyi was completely stunned and looked blank.
"Um, what did you just mean, Junior Sister?"
"Um... Don't you even understand this?"
Seeing Chen Tianyi's blank expression, Hu Ke'er was also taken aback for a moment and showed a look of surprise.
This was just junior - high - school physics knowledge. She never expected that the scientific level of this world would be so backward!
"Forget it. Since you don't understand, I won't talk to you about these principles. I'll just put it simply."
Hu Ke'er pouted and said.
"Actually, what I mean is that the temperature control during your refining was unreasonable, causing a lot of spiritual energy not to attach to the spirit stones. That's why the quality of the spirit stones was so poor. Senior Brother, what do you think of the quality of the spirit stones inside the brick you dug out just now?"
"The purity was extremely high. I've never seen spirit stones with such high purity. It's a pity that we ended up benefiting that bastard surnamed Zhao!"
"Um, it seems that your interpersonal relationships in the sect aren't very good, Senior Brother~"
Seeing Chen Tianyi getting angry, Hu Ke'er also joked.
"To some extent. The cultivation world is not much different from the secular world. It's all about the law of the jungle. Those guys used to bully me, and I've paid them back a bit. So our relationships aren't that great~"
Chen Tianyi also spread his hands helplessly.
"Don't worry, Senior Brother. From now on, I'll make super - powerful weapons for you. No one will be able to bully you anymore~"
As Hu Ke'er said this, she puffed out her chest and patted it.
"How can a junior sister protect a senior brother? It's okay. I can handle these things myself."
Chen Tianyi waved his hand and then changed the topic back to the main point.
"So, Junior Sister, do you know how to refine spirit stones now?"
"Of course! However, my refining method is different from yours, and I'll need your help during the refining process!"
As Hu Ke'er said this, her eyes sparkled as she looked at Chen Tianyi.
"No problem. As long as you can make high - purity spirit stones, I'll do whatever you need me to do. If we can stably produce high - quality spirit stones, even the sect master will come to meet you in person!"
"Um, since that's the case, Senior Brother, could you take out 200 grams of spirit stones for me to try first?"
"200 grams?"
Chen Tianyi asked in confusion.
"Oops, I forgot that you don't know the measurement units in my world. Do you have a scale here? I'll do it myself!"
"Yes."
As soon as he finished speaking, Chen Tianyi took out a small scale from his sleeve.
"Also, Senior Brother, how high a temperature of flame can you produce?"
Hu Ke'er then asked.
"Temperature?"
Chen Tianyi still looked blank.
"Anyway, just show me your most powerful flame first."
"Okay!"
Hearing Hu Ke'er's words, Chen Tianyi made a hand seal and then recited a mantra towards the empty space in front of him.
"Three - Flavor True Fire, arise!"
As Chen Tianyi's voice fell, Hu Ke'er heard a "boom", and immediately white flames appeared in front of him.
"So hot!"
The space in the cultivation room wasn't very large. As soon as the flames appeared, Hu Ke'er felt a burning pain.
"Shouldn't this temperature be more powerful than the flames in the refining room?"
"Definitely. Although the one in the refining room is the Earth - Core Flame, this is my Three - Flavor True Fire. It's stronger. However, in terms of convenience, the Earth - Core Flame is better. My Three - Flavor True Fire consumes spiritual energy quite quickly. If I keep using it, I can only maintain it for at most two quarters of an hour."
"Um, as long as the temperature is high enough, even five minutes will be enough."
As Hu Ke'er said this, she asked Chen Tianyi to take out the origin stones and then directly threw them into the white Three - Flavor True Fire.
"Zizz!"
As soon as the origin stones were thrown into the Three - Flavor True Fire, they made a "zizz" sound like roasting meat. At the same time, a red mist slowly rose!
"Great! The temperature is high enough!"
Hu Ke'er's eyes lit up as she watched the slowly rising red mist, and then she stared intently and said,
"Senior Brother, take off your clothes!"
"Ah?"
Hearing Hu Ke'er's words, Chen Tianyi's face instantly turned red.
"Don't just stand there in a daze, Senior Brother. Quickly give me the gauze robe you're wearing over your Taoist robe!"
"Okay, okay, okay!"
Chen Tianyi nodded repeatedly and then handed the gauze robe he was wearing to Hu Ke'er.
As soon as Hu Ke'er took the gauze robe, she covered the slowly rising red mist with it.
"No, the temperature isn't low enough. Do you have any Ice Talismans, Senior Brother?"
"Yes!"
As he said this, Chen Tianyi quickly threw out an Ice Talisman. The talisman paper landed right on the gauze robe.
"Crunch, crunch, crunch!"
As soon as the Ice Talisman landed on the gauze robe, a strong chill erupted. The red mist instantly condensed and turned into small particles that attached to the gauze robe.
"We did it!"
Hu Ke'er placed the gauze robe on the ground, and the corners of her mouth curled up slightly.
"Next, we just need to scrape off these condensed spirit stones!"
"Let me see!"
Hearing Hu Ke'er's words, Chen Tianyi rushed over excitedly and then carefully examined the spirit - stone particles condensed on the gauze robe.
"The purity... Um~ Junior Sister, you're so amazing!"
Chen Tianyi picked up the gauze robe and exclaimed in admiration!
"Hehe, it's nothing~"
