"Boom!"
Flames shot out radially from Chen Tianyi's palm, exactly following the trajectory of his released spiritual energy.
"Wow!"
Chen Tianyi was also startled to see the spiritual energy from his palm ignited by Hu Ke'er. Panicking, he quickly waved his hand, trying to put out the flames.
"Hmm, this spiritual energy can burn like natural gas, and its temperature seems to far exceed that of ordinary flames."
Hu Ke'er didn't seem panicked at all when seeing the spiritual energy ignited. Instead, she looked calm and thoughtfully nodded her head.
"Are you trying to burn me to death?!"
Although it was Chen Tianyi's first time doing such an experiment, he felt real danger when the flames were ignited on his palm.
"I've got an idea!"
Hu Ke'er immediately came up with a good way to make weapons. Since the spiritual energy could burn, she could make several simple but powerful weapons based on this!
"Huh?"
Chen Tianyi was stunned for a moment when he saw the confident light flashing in Hu Ke'er's eyes. Ignoring the burn on his hand, he asked, "What did you think of?"
"It's hard to explain in a short time. But can you help me?"
Hu Ke'er said, looking at Chen Tianyi hopefully.
"Huh? If it's another dangerous experiment like just now, I..."
"Don't worry. It's not dangerous. But you have to help me forge some sealed metal cans. I also need some hollow rods and some small parts. I can draw the specific blueprints for you."
Hu Ke'er said, looking around.
"Why don't you even have a place to draw blueprints here?"
"Or you can just draw on the wall with this."
Chen Tianyi took out a small black dagger from his waist and handed it to Hu Ke'er.
"Okay, this will do. You go find some metal for forging weapons first. By the time you come back, I should have finished the blueprints."
Before Chen Tianyi could answer, Hu Ke'er had already started carving the blueprints on the wall with the dagger.
"Okay!"
Seeing how absorbed Hu Ke'er was, Chen Tianyi nodded.
"This girl is a bit quirky, but she's really interesting!"
Thinking of Hu Ke'er's usual stubbornness and her previous ingenious idea of igniting his spiritual energy, Chen Tianyi became extremely interested in what Hu Ke'er was going to do next.
"Done. These will do!"
After finishing drawing the blueprints, Hu Ke'er clapped her hands. But when she turned around, she saw Chen Tianyi sitting cross-legged on the ground, looking at her seriously.
"Hmm, when did you come back? Have you been waiting for a long time?"
Feeling Chen Tianyi's gaze, Hu Ke'er blushed slightly.
"Not really. I just didn't want to disturb you because you looked so serious. By the way, this is the metal you wanted."
Chen Tianyi said, pointing to the metal beside him.
"Thanks."
Hu Ke'er walked over to the metal, gently touched it with her hand, and then tapped it with her fist.
"The hardness, toughness, and ductility of this metal are all good."
Then Hu Ke'er looked at Chen Tianyi again.
"Next, I'll have to trouble you to make these things according to my blueprints."
"Huh? You mean the rods and cans drawn on the wall?"
Hearing Hu Ke'er's words, Chen Tianyi was slightly stunned.
"Although these materials are ordinary, they can be used to make a flying sword. Can these bottles and cans really help you pass the entrance test?"
"Hmm, don't worry about that. I have my own way."
Hu Ke'er said, with a slight smile on her lips, looking confident.
"Okay then."
Seeing Hu Ke'er's confident look, Chen Tianyi didn't say much. Then he opened the lid of the Earth Core Flame and started forging the required parts according to Hu Ke'er's blueprints.
"Done!"
After a long time, Chen Tianyi finally forged all the things that Hu Ke'er had drawn on the wall with the dagger.
"What are these things you asked me to make for?"
Chen Tianyi looked at Hu Ke'er in confusion.
"I have my own uses for them. But before I assemble them, can you help cool down these newly forged materials?"
Hu Ke'er requested.
"No problem."
Chen Tianyi said, then threw out a yellow paper.
"Water come!"
As Chen Tianyi's voice fell, the yellow paper emitted a blue light and turned into a ball of water. Then it splashed onto the forged parts with a "splash". The parts immediately emitted white smoke with a "hiss", making the weapon-forging room like a steam room.
"So amazing!"
Seeing Chen Tianyi use the talisman to create water out of thin air, Hu Ke'er exclaimed in surprise. It seemed that there were still many uses of spiritual energy that she didn't know. If she wanted to figure out the various characteristics of spiritual energy, she would have to spend more time studying it in the future!
But now time was tight. She had to make a suitable weapon first to pass the entrance test!
Thinking this, Hu Ke'er quickly began to assemble these parts. It took her about an hour to finish assembling the two sets of equipment.
"Phew~ It's really tiring. I didn't expect assembling to be so difficult!"
Hu Ke'er had Chen Tianyi's help when assembling. Otherwise, it would have taken her even more time.
"Is this the weapon you were talking about?"
After Hu Ke'er finished assembling the two pieces of equipment she designed, Chen Tianyi frowned.
"Actually, it can't really be called a weapon. Since it's a weapon driven by spiritual energy, let's call it a spirit-driven weapon."
Hu Ke'er said, with a satisfied smile on her lips.
"What spirit-driven weapon? You're not really going to use this iron can and this rod to pass the entrance test, are you? Otherwise, I'll forge a flying sword for you..."
"Flying sword? I don't have spiritual energy and I don't know how to use a flying sword. Even if you make a flying sword for me, I won't know how to use it!"
Hu Ke'er retorted.
"These two things aren't finished products yet. I still need your spiritual energy to complete them."
One of the two weapons Hu Ke'er made was a flamethrower made by connecting a backpack-style spiritual energy can to a valve and a rod. The other was a simple flintlock gun. Spiritual energy was essential to drive these two weapons.
"My spiritual energy?"
Hearing Hu Ke'er's words, Chen Tianyi was stunned.
"Yes. You just need to inject your spiritual energy into this can and these small hollow beads."
"Hmm, it's okay to inject spiritual energy into the can. But these beads are sealed. It may not be possible to seal the spiritual energy inside. If you really want small beads with spiritual energy sealed inside, you can just grind spirit stones of about the right size!"
"No. Spirit stones have too many impurities and are too heavy... By the way, how do you inject spiritual energy into the talisman paper?"
"Just draw runes on the talisman paper."
"Then why don't you try to draw explosive runes on the small beads for me!"
Hearing Chen Tianyi's words, Hu Ke'er realized there was a flaw in her design. According to the original plan, the flintlock gun couldn't be used. But it seemed the bullets could still be used after some modification.
"Hmm, okay..."
