"Tch, the dead fish-eyed old man who always likes to perfunctory..."

Kuroba Kaito complained in a low voice, then turned slightly sideways without energy, grabbed an incoming ax blade, and slid towards the stone pier that was half a person tall.

Immediately, he pulled out the stone sword with characters engraved on the handle, and looked at it carefully for a while, except for the word 'dragon', he didn't see any other clues.

Ye Genyi manipulated the nanorobot to re-fix the linkage shaft of the gear, and also went to the stone pier to check it, and said:

"There are no other mechanisms in the room. If the so-called 'Nioh Stone' is not a joke of Misui Kichiemon, then this sword should be the clue to find it."

"Dragon... Confused person... Offer an artifact to me..."

At this moment, a flash of light suddenly flashed in Kuroba Kaito's mind, and he said excitedly: "Brother, I think I know where that gem is!"

…

Insert the stone sword back into the stone pier.

The two left the secret room and walked towards the exit covered by the red mist below the stone steps.

There was also a stone door installed here. Ye Geng tried to push it, but found that it was not locked. Using nano-robots to investigate, there were no traces of artificial carvings around the passage.

There is no agency?

He was a little strange at first, but after thinking about it, he understood the reason.

I am afraid that Sanshui Kichiemon took advantage of the survival psychology of the trapped people, so he set the cave in the hot spring, and set the exit at the entrance that seemed to be blocked by fog, but in fact there was no danger at all. below.

The return to the ground was fairly smooth.

On the way, Kaito Kuroba also explained the meaning of the inscription left by Kichiemon Sansui:

"The so-called 'Yogo' is to combine the Sanshui of Misui Kichiemon and the dragon to form the word 'Taki', and Taki refers to the rapid flow of water...combined with the code on the stone lantern, 'Everyone The elders gathered at the "Yin Ji Ji Zhi Ji Ji" is not the place full of bones in the secret room, because there is no treasure there, the real "Yan Ji Ji Ji Ji Ji Ji" refers to the place in front of us, where many carp live The water pool, the King Ren's Stone must be hidden in it!"

"Oh, really? Waiting for your good news."

Ye Geng took half a step back and made a gesture of please.

"Ahem, bro," Kuroba Kaito said awkwardly, "That's not the point, the point is that there are fishes down there..."

"Well, if that's the case, then I'll go." Ye Geng nodded and said, "Please help me see how deep the water is."

"Uh..." Kaito Kuroba hesitated for a moment, and said suspiciously: "Brother, although you said 'in this case, I'll go', you didn't look joking on your face, but I always feel that as long as you Turn your back and you'll immediately push me into the water..."

"Huh? Very sharp." Ye Gengyi admitted without hesitation: "That's right, but isn't it you who first suggested that you want to enjoy the tension and excitement during the challenge?"

Hey, so the topic is not over yet? !

Hei Yu broke into sweat, waved his hands, and said firmly: "No, no need, the most urgent thing is to find gems first."

"You are quite practical, give me the chain gun." Ye Gengyi said.

Kuroba Kaito said "Oh", and while handing over the gun, he asked, "Brother, what are you doing with this for diving?"

"Measuring the water depth."

Ye Geng weighed the iron hook on the gun head, checked the weight, aimed at a place where the carp could not be seen, and pulled the trigger as close as possible to the water surface.

Is the hypotenuse about 5 meters... That means the height should be around 3 meters.

"The power is enough, no need to dive."

Ye Geng returned the chain gun to Kaito Kuroba, and used nano-robots to condense a fish-shaped submarine with his backhand, and put it into the water.

"Brother, this thing is too easy to use..." A strange thief showed envious eyes.

"Even if the data model framework is built, it needs to be fine-tuned according to the real-time feedback value. Without the assistance of the 'core', no matter how smart you are, you can't use this." Ye Gengyi said.

"It's really a pity." Kaito Kuroba sighed.

"Who says it's not." Ye Geng rested his chin with one hand and murmured in a low voice: "If the human brain can be modified to add a function similar to the 'core'..."

As he spoke, he couldn't help turning his head to look at a certain strange thief.

Kuroba Kaito shuddered, subconsciously took a few steps back, and reminded: "Brother...gem, we are here to find gems..."

…

The darkness under the water, coupled with the resistance, made it more difficult for nano-submarines to explore.

During this period, Ye Gengyi had to recall it many times to recharge it. At the same time, he naturally didn't forget to take out his electric shock gloves to take care of a sad treasure hunter.

It took more than 40 minutes of searching back and forth in this way.

Ye Gengyi finally found the Niwang Stone on the rock at the bottom of the pool.

"found it."

In a word, the drowsy Kuroba Kaito immediately revived.

There was a light "poof", a diamond the size of an adult's fist broke through the water, together with the bright silver liquid surrounding it, spun a few times in the air, and landed on the leaf together. More hands.

"Remember to split the price in half."

Ye Geng threw a diamond to Kaito Kuroba.

He knew that this kid had principles and didn't intend to destroy them, but he had to return the owner's things, and he shouldn't have any psychological pressure to take away and sell them for money like this.

"Oh, it really isn't the one I was looking for."

Here, Kaito Kuroba has checked the gem against the moonlight.

He had no objection to Ye Gengyi's proposal, but when the two were about to leave, an accident occurred.

what sound?

Ye Geng frowned, keenly aware of some kind of danger.

"Brother! The house is shaking, so it shouldn't be an earthquake!" Kaito Kuroba said.

"No~lightnovelpub.net~ is the trigger mechanism, give me the diamond!"

Ye Gengyi took back the King of Ren stone, jumped into the water, like a **** fish, according to the coordinates, quickly dived to the location where the diamond was found before, and put the thing back again.

He was not in a hurry to float up, but waited quietly in the water for a few seconds to confirm that the shock and the current had calmed down, and then he swam up.

At this time, it can still be called the shore area. In just this moment, the water level has increased by nearly 20 centimeters.

That should be the switch of a water gate. Apart from flying out directly, I am afraid that there is no way to escape the range of the water flow in a safe time just by running.

While thinking, Ye Geng wiped the water off his face, took off his shirt and twisted it: "Have you brought dry clothes?"

"I brought it, but apart from this body used for camouflage, the rest are in the car." Kaito Kuroba said.
