"And there are some special things in the cave... Yes, there are several people walking along the spring of the cave to explore the way inside, but no one can come up..." the boss of the hot spring villa turned pale here.

This hot spring villa is his cash cow. He has opened the hot spring villa for so long. He knows this hole better than anyone. The water quality of the Dongfu hot spring in the cave is much better than that outside. This is the characteristic here.

There are more than a dozen large and small hot spring entertainment places nearby, but no place can match his business here. It is the hot spring in the cave, plus some advertising gimmicks that can cure all diseases and prolong life. Therefore, the boss has made a lot of money these years by relying on the hot spring pool in the cave.

Although several guests disappeared from this cave mountain for no reason, this matter was suppressed by him. Because once someone knows that there is an accident here, who dares to come to his Dongfu hot spring to soak in the hot spring? Don't you want to die?

However, the situation is urgent today. The monster was clearly photographed by the supervisor. Now the monster is hiding in the cave. If he is not found out, he may not be able to sleep every night. In addition, the person who came here today is not ordinary. He dare not hide anything.

"Bring me the design drawings inside." Masako Asada frowned.

"Yes... I'll get it right away." The boss hurriedly called someone to take the design drawing of the hot spring pool in the cave.

The design drawing shows that the area here is not large. There are several artificial hot spring pools, and the terrain inside is not complex. And now there is no one inside. If there is no other exit, the destroyer will never get away once the cave is blocked.

"Is there an underground river leading to other places in this place?" Masako Asada combined the plans in his hands.

"Yes... There is a secret passage in the hot spring pool we designed. The secret passage is hidden in the water. No one knows where it leads. Because I have been to an exploration team before, and I haven't come out since I went in." The shopkeeper said, "later, we were afraid of accidents, so we locked the place with an iron gate. What we were afraid of was that some curious people would try to get in and play, and then something would happen."

"This is the case." Masako Asada introduced the situation here to yehaoxuan, and then asked, "what do you think?"

"Go in and catch people." Yehaoxuan only said these four simple words.

"If there is a secret passage inside, he may go to another place from the underground river." Masako Asada said with some anxiety.

The underground river extends in all directions. No one knows where it will lead. In addition, this hill is located in the center of the hot spring town. The terrain of the underground river is more complex. If the destroyer really gets into it in a hurry, I'm afraid it will be more difficult to catch him.

"No, we have already locked the underground river with iron locks. He can't get through it." The boss knew a little Chinese. He understood Masako Asada.

Yehaoxuan glanced at the boss and said nothing.

The boss's face turned pale. He thought that the guy he had just shot was a monster... The face photographed by the supervisor made him never forget in his life. They have a small iron gate. Can they really trap the monster here?

"Now on the gene detector, how far is he from us?" Yehaoxuan asked.

Masako Asada took out a radar like thing with an LCD connected to it. This is the gene detector that Japan has made with ambition to explore extraterrestrial life. The accuracy is very high. Once something with non earth biological genes comes out, it will give an alarm, and emit electromagnetic waves to lock the position of the creature. The locking error is less than 10 meters.

On today's LCD screen, I can only see a fiery red shadow shrinking in it and not moving. The displayed things are just like those scanned by thermal imaging.

"About 130 meters away from us, the length of Dongshan mountain plus the length of Wenquan lake is only 80 meters... That is to say... He has now run to the other side of the underground river through the underground river." Masako Asada calculated the distance path.

"Gather heavy weapons, surround the hole, and I'll go in and have a look." Yehaoxuan said.

"I'll go with you." Masako Asada said.

"Are you sure you can swim?" Yehaoxuan asked back.

"I have participated in the sports meeting... I have won three swimming championships in succession, and I have participated in deep-sea diving training. No one is more suitable than me." Masako Asada said, "what's more, this is the trouble caused by the scum of our nation, so the main responsibility lies with me. Now that my brother is not here, I want to replace him."

"Is there anything else you can't do?" Yehaoxuan is a little silly. He used to think that Asada's brother and sister were all from special departments, but Asada Nakamura was like an agent, and Asada Masako was just a senior researcher, but he didn't think that Asada Masako was also an agent. Does she have many professional skills?

"Yes... Except that I can't fly the space shuttle of the Republic of magnesium, there is really no such thing." Masako Asada said seriously.

"OK, I'll go with you to find someone to guard in the mountain mansion hot spring. The outside is suppressed by heavy fire. You and I will go down from the underground river to see where the guy is hiding." Yehaoxuan said.

"I'll get ready right away." Masako Asada nodded. She turned around and went to arrange.

Now Masako Asada is taking the place of her brother, so her words are also very important. She made a few calls and ordered that a steady stream of essential goods would be delivered immediately.

There are diving suits and oxygen cylinders. There are also underground road scanners. They are afraid that there are too many branches in the underground river. If they lose their way below, they will be in trouble. With this scanner, they can clearly scan the underground river under the whole mountain.

The special police and a self-defense force were mobilized. Martial law was imposed inside and outside. Irrelevant people in the hot spring villa were temporarily avoided.

"I... when can I start my business?" The boss of the hot spring villa asked Masako Asada.

"Half a year from now." Asada shinko said faintly. She mentioned all her equipment and rowed with yehaoxuan toward the cave.

"Half... Half a year." The boss is so stupid that he desperately wants to know what he will eat in the past six months?

A team of special police guarded the hot spring in the cave. There was a naturally generated clock milk at the entrance. The fluorite in the cave gave off a colorful glow. It was a hot spring coming out of an underground river. The boss here was also ingenious. He made several warm spring pools in this place manually, which could be used by dozens of people to soak in hot springs.

This place is obviously the characteristic of this hot spring villa. Apart from other things, the atmosphere of the five lights in this cave makes you linger.

In a small boat, yehaoxuan and Masako Asada came to the deepest part of the cave hot spring, where several incandescent lights had been installed to illuminate the lights in the cave.

"Two meters under the water, there is an underground river with a diameter of about two meters wide. I don't know where it leads. But the oxygen cylinder may be blocked." A geologist has checked here. His data is that the hole with a diameter of one meter may become narrower as it moves inward. It is impossible for the oxygen cylinder to pass through. As for the length of the hole, he has not yet got the data.

"We can only bring a portable oxygen bottle in. We have half an hour at most. If we can't reach our heads, we have to come back." Masako Asada said.

"Half an hour is enough." Yehaoxuan smiled. He put on his diving goggles and took his equipment. They had already changed into black swimsuits. The swimsuits were specially made for divers. They were tight and flexible. They were most suitable for underwater operations.

"This oxygen cylinder can last up to 30 minutes, so we can only probe forward for 15 minutes. We can't find the way ahead. We'll be back soon." Masako Asada confesses in San.

"I see. Is that guy still there? How far is he from us?" Yehaoxuan asked.

"He's gone?" Masako Asada picked up the gene detector and was surprised. The screen was dark. The destroyer was still displayed on it. As the detector moved forward, it was getting closer and closer to him. But now he completely disappeared out of thin air.

"Did he run away again?" Masako Asada murmured.

"It may be wide on the other side of the underground river." Yehaoxuan picked up a portable oxygen bottle and put it on him. Even without the help of oxygen, he can keep his breath under the water for a long time. Because of Hao Ran's true Qi, he can use the turtle breathing method to minimize the oxygen his body needs.

With a plop, ye haoxuan dived into the water. Masako Asada also put on his equipment and immediately jumped into the water.

The opening of the cave is not very wide. The open lights on the two heads can clearly show the underwater world. The diameter of the cave is about one meter, and uneven stones are planted around it. The two people use both hands to push the stones in the cave forward, but the speed is much faster.

Yehaoxuan didn't use the portable oxygen bottle at all. His portable oxygen bottle was always hung around his waist. This path was nothing to him at all, and his time of self-restraint even exceeded that of this small oxygen cylinder.

Masako Asada is also specially trained, so she doesn't need to deliberately hold the oxygen bottle to her mouth to breathe all the time. She always swims forward for three to five minutes before she takes a sip from the oxygen bottle. This portable oxygen bottle is specially made, so she can't suck water from her mouth.

I don't know. More than ten minutes have passed. The hole in front of them is getting narrower and narrower. Before, they can move their hands forward by a large margin. However, as they move behind, the range of their movement is getting smaller and smaller, because the space is not as big as when they first came here.
