"How about we clear these stones bit by bit?" Chen Tianyi suggested in a soft voice.
"Hmm, slowly digging is an option, but the efficiency is too low. And we don't know how many broken stones are blocking the way behind. If we remove the outer stones and cause the inner ones to collapse again, that would be bad!"
"Then what do you suggest, Junior Sister?" Hearing Hu Ke'er's words, Chen Tianyi frowned and asked.
"Senior Brother, do you have any way to get the architectural drawings of this place?"
If she could figure out the building structure inside, she might be able to use the detonation talismans for directional blasting. In that case, the efficiency would be greatly improved, and they could re - enter the Spirit Stone Refining Room without spending too much effort.
This detonation talisman was really useful. Although its power was not as great as C4, in terms of portability and stability, it was on par with C4, and might even exceed it.
"I really don't know about this. I'll have to ask Uncle - Master."
"Okay, then let's go ask Uncle - Master first."
After saying that, the two went to the Flying Tiger Hall and found Uncle - Master Zheng. After explaining their purpose, Uncle - Master Zheng frowned slightly.
"I really don't know where the architectural drawings are."
"Eh?" Hearing Uncle - Master Zheng's words, Hu Ke'er was full of confusion.
"How could this be? Does it mean we have to dig bit by bit?"
"No need for that. You want the structure diagram just to know where the load - bearing beams are. I used to stay in the Spirit Stone Refining Room for a long time. I'm sure there are no load - bearing beams in a few locations. But we have to enter through the ore vein to reach the side of the Spirit Stone Refining Room from there." Uncle - Master Zheng said.
"That's okay. Please take us in, Uncle - Master!"
"I'm not going. That place is so damp and dark. It's too uncomfortable. I can't bear such hardships."
"Eh?" Hearing Uncle - Master Zheng's refusal, Hu Ke'er was unexpectedly surprised.
Wasn't Uncle - Master Zheng always on Senior Brother's side before? Why was he even unwilling to help with such a small thing?
"Although I won't go myself, I can show you the way."
Saying that, Uncle - Master Zheng casually took out a yellow talisman from his bosom and threw it into the air.
"Go. Take them to the place I have in mind."
"Chirp~"
The yellow talisman emitted a bright light. When the light dissipated, it had turned into a yellow paper crane.
"Wow, so amazing!" Seeing the yellow paper crane flying in the air, Hu Ke'er exclaimed in surprise.
"What is this? Can I learn it?"
"Chirp chirp~" Before Hu Ke'er could take a closer look, the yellow paper crane flew towards the Yuan Stone Ore Vein.
"Junior Sister, let's go first. It'll be troublesome if we lose it later!" Chen Tianyi said as he grabbed Hu Ke'er's hand and took out his flying sword to chase after it.
"Senior Brother, this paper crane doesn't fly fast. You don't need to be so nervous~"
After getting on the flying sword, Hu Ke'er quickly caught up with the paper crane, and it was flying very slowly.
"This is Uncle - Master's shikigami. Don't look at it flying slowly now. It might suddenly speed up later."
"I see..."
"Chirp~" As soon as Hu Ke'er's voice fell, the paper crane let out a clear long cry, and its speed suddenly increased.
"Hold on tight!" Seeing this, Chen Tianyi reminded her, then slightly changed the gesture to control the flying sword, and the speed of the flying sword suddenly accelerated.
"Wow!" Although Hu Ke'er heard Chen Tianyi's reminder, she still panicked a little and grabbed Chen Tianyi's waist at the moment of acceleration because her reaction was a bit slow.
"Are you okay, Junior Sister?" Hearing Hu Ke'er's exclamation, Chen Tianyi asked with concern.
"I'm fine..." After standing firmly, Hu Ke'er let go of the hand around Chen Tianyi's waist and breathed a sigh of relief.
"Chirp~ Chirp~ Chirp~" Soon, Hu Ke'er felt the speed of the flying sword slow down, and then heard the continuous long cries of the paper crane, which was circling not far away.
"This should be the place. We're here." Seeing the state of the paper crane not far away, Chen Tianyi said softly.
"Okay." After landing, Hu Ke'er looked at the circling paper crane and waved to it.
"Chirp~" The paper crane landed on Hu Ke'er's outstretched palm very spiritually.
"Thank you so much this time~"
"Chirp!"
"Whoosh!" As the paper crane raised its head and let out a long cry, flames suddenly emerged from its body and it burned to ashes in an instant.
"Senior Brother, this..." Seeing the paper crane suddenly burn to ashes, Hu Ke'er frowned and exclaimed in surprise.
"It's okay. This is just one of Uncle - Master's shikigami. After it burns, he can draw another talisman to summon it again!"
"I see!" Hearing Chen Tianyi's words, Hu Ke'er suddenly got excited.
"Senior Brother, do you know the principle of this shikigami?"
"Principle?" Chen Tianyi frowned, a bit confused.
"You mean why we can summon a shikigami with such a talisman?" Hu Ke'er explained her question just now.
"I really don't know about this." Chen Tianyi shook his head.
"Then do you know why this talisman can fly and make sounds?"
"I don't know this either." Chen Tianyi said apologetically.
"Okay. But this paper crane should be supported by energy, right? Otherwise, how could it fly around like this!"
"If we talk about energy, spiritual energy should count, right?" Chen Tianyi counter - questioned.
"Yes, of course it does!" Hu Ke'er answered affirmatively.
"Then this problem is much simpler. The energy you mentioned just now comes from the spiritual energy on the talisman."
"The spiritual energy on the talisman... Just like the detonation talisman?" Hearing Chen Tianyi's words, Hu Ke'er suddenly realized.
"Right. There should be spiritual energy on this talisman. It makes sense if we use spiritual energy as energy. As for the reason why this paper crane turns into a paper crane, it should be the runes on the talisman. These runes are like a circuit board with pre - written circuits..."
"Junior Sister, Junior Sister?"
"Huh?" Hu Ke'er was awakened by Chen Tianyi and then came back to her senses.
"Junior Sister, what's wrong with you? You seemed to be in a daze just now. Shouldn't we quickly use the detonation talismans to blast a hole and go into the Spirit Stone Refining Room to take a look?"
"Ah, sorry, Senior Brother. I was a bit distracted just now. I'll do it right away."
Saying that, Hu Ke'er took out all the small iron beads engraved with detonation talismans from her bosom and placed them where the paper crane had disappeared.
"Okay. Next, Senior Brother just needs to help me detonate them!" After placing the detonation talismans, Hu Ke'er quickly hid behind Chen Tianyi.
"Okay."
