"The cave is very deep, and there are many forks and branches inside, which is not much different from ordinary caves. The only thing to be careful is that there are many insects, snakes, birds and bats that like the shade. The weirdest thing is that no matter how strong the light source is, it will become very dim..."

At night, four boys and Buddy gathered together after the two girls fell asleep and listened to the first mate's preliminary investigation of the inside of the cave.

"So weird? It seems that he is not at the wrong place." Huijie was very excited after hearing the introduction. Since he became a profession of the man in black, they have encountered more and more strange things. If the first mate now says that it is exactly the same as an ordinary cave, it will make people lose interest.

"Budy, are there any other roads?" Duan Guoyu asked Budy after thinking for a while.

People who often play outdoors know that although the forest and mountain drilling and cave exploration are both outdoor projects, there are quite a lot of technical differences between the two. Most of the time, the forest and mountain passes through the forest is still on the surface. Occasionally, the mountain passes through the mountain is thrilling, but the vision is wide and has a unique flavor. Cave exploration is an underground worker. In the dark cave, it not only tests people's physical strength, climbing and balance ability, but also tests people's courage and psychological endurance. In addition, underground rivers are often accompanied by underground rivers (there are many caves in the south, so don't know if there is any mistake). When necessary, even dive into the underground river for exploration is extremely risky. At the same time, the most terrible thing about underground cave exploration is that once you are lost inside, you are more dangerous and terrible than losing direction on the surface. Many times, even if you want to ask for help, you cannot send a helping signal and be trapped in the cave...

Therefore, Duan Guowu, who is still half a master of outdoor sports, knows the degree of danger, especially in this kind of operation without any support or even a secret adventure, he does not want to go deep into the cave.

"Other roads... don't know..." Budi answered helplessly. "I am the interstellar explorers who came to Earth and observed them for a few years. After they were all dead, I lost interest and never paid attention to them. There are many earthquakes in this area, and the landforms have changed dramatically. If I can find these hills, it is already a great fortune. As for how to find the spacecraft, I really don't know..."

"Drop!" "Tsk!" "Damn!" Several middle fingers and contemptuous eyes were swung at Budi. After staying with Budi for a long time, everyone also knew that sometimes Budi was omnipotent, but sometimes... Budi was very unreliable...

"Although I can't do it, someone has it..." Budi also knew the reason why he caused everyone's contempt, so he hurriedly pointed his little claw and turned everyone's eyes to the first mate.

"Are you talking about Qu Xinyan?" The first mate knew that Budi was not referring to him. "Although she had something in her mind, it was not omnipotent after all. If something went wrong, I would have nothing to do. I would be sorry to trap her in..."

"Oh..." The three and one bear made a boo together.

"It's only been a few days, and I can already sacrifice my life and shed blood for others..."

"Even... the revolutionaries back then were just like this..."

"Everyone says that women in love are the stupidest. It seems that one more thing is that men in love are the bravest..."

"I remember when they came out of the hole, they seemed to be holding hands. The one was called sticky tight... and they refused to let go when they were eating..."

"I said why the meal tonight is a little sweet. It turns out that the sweetness comes from here..."

"Did the first mate take advantage of the time he was in the cave to do everything he should do..."

The first mate was so blushed by everyone's words and words. Although he wanted to explain something, he really didn't explain it at this time. The more he explained, the more he seemed like that, the more he was, the darker he was...

After a short teasing and joking, everyone no longer made fun of the big mate. The first brother, a family with emotional difficulties, is indeed worth celebrating when they can get rid of the life of a bachelor, but now everyone has more important things to face.

"If there is really no other way, then I can only break into it with my teeth!"

There was no other way, and Duan Guoyu had to decide to explore the hole hard. With this determination, the preparations were immediately launched. After a while, the remaining materials and various equipment that everyone now had been checked and counted and entered the orders (don't forget the role of Budi's electronic chip).

The food is not included in the reserves of the girl. The four people can eat six people for five days. There are still so many left, thanks to the hunting and wild vegetables that Duan Guoyu and Zhen Lan have been hunting and picking wild vegetables. However, after entering the cave, it is estimated that such a source of supply will be lost. In addition to the 30-meter-long safety rope required for the cave, there are 500-meter-long lead ropes and about 2,000-meter-long spider silk that can be used. However, considering the presence of outsiders and the unrecyclable and reusable spider silk, although the spider silk is sufficiently long, everyone still keeps it for spare. As for sleeping bags and tents and changing laundry equipment, those that can be brought will naturally be brought, and those that are not needed will naturally be abandoned to reduce the load and space. Since it is not expected that people in the cave will not carry oxygen equipment, if there is no oxygen and there is toxic gas accumulation in the cave, everyone can only withdraw and find another way.

There are also very important lighting power issues in the cave. If you are working on the surface, everyone can also use small solar panels modified by Budi and Duan Guoyu to charge the batteries. However, if you are working in the cave, everyone can only spend some effort to charge the batteries with a small hand-crank generator. If these two charging devices are replaced by other outdoor teams, almost no one will carry them, because those outdoor donkeys usually only return to the city in one action, and they never really plan to stay outdoors for a long time. Duan Guoyu and others are different. Although they also return to the city after one action, don’t forget that there is an important guy in their team who eats electricity - Budi! If this guy doesn’t have a battery, it’s no different from being dead!

The last thing to check was some secret equipment - weapons brought by everyone during this operation.

Due to the strict control of weapons by China, the self-defense equipment that everyone publicly publicly disclosed was not even a hilt except for the multiple knifes they carried. However, this does not mean that the boys did not have any weapons at all. Some special weapons were hidden in their packages. In addition to two single heating weapons disguised as hot water bottles modified (these traditional equipment were not dared to write too much. I wrote them in one chapter last time and were deleted in detail. Everyone understands), there are two web gun equipment made of specially enhanced spider silk. Although the caliber is small, it is not a weapon of destruction, but don't underestimate it. Budi is very sure that as long as he does not encounter large alien creatures and super-strong space warriors, this thing can bind it and lose its movement.

In addition to some special equipment, the machine originally wanted to bring the newly formed exoskeleton armor to move, but in the end it gave up because of the poor exoskeleton endurance, small strength and inconvenient transportation.
