"Okay. Then you should take a break here. Wei Hongwei and I went down first. When Angkor comes back, I'll sue him and you're here. Wang Feng thought for a while and added, "Do you still have hot water in your space?" You drink first. ”

"Yes, got it." Xie Tingting smiled, waved her hand and said, "Go quickly." ”

Wang Feng and Wei Hongwei didn't say anything more, and went down after beckoning Meow and Tyson. Baihu followed a few steps, and finally turned back and decided to stay with Xie Tingting.

Xie Tingting took out the hot water from the space, held a cup by herself, and poured some for the white tiger. However, the white tiger was afraid of heat, so he didn't drink it after smelling it.

The white tiger also seemed to see that Xie Tingting was a little uncomfortable, and looked at Xie Tingting worriedly with a pair of beautiful big blue eyes. Xie Tingting smiled and patted the white tiger's head gently, and it nested obediently at Xie Tingting's feet, rubbing Xie Tingting's legs from time to time.

Near the elevator at the main entrance on the first floor.

"Do you know where the ventilation ducts are on this floor?" The two of them only walked around the first floor, and finally returned to the gate, Wei Hongwei asked Wang Fengdao.

Wang Feng shook his head.

It's a cheat. They have all seen the ceiling, there are a lot of pipe openings, basically every room, and there is one in the corridor every other distance, but they are all pipe openings of the air conditioning system. The pipes should have been connected to the ground as well, but they were too thin. Tyson must not be able to get in, Meow can barely get in, but it is difficult to turn around.

No, Meow doesn't seem to be able to get in. The child was too plump, and the pipes were spacious, but the air holes were only the size of the mouth of the bowl. Meow's round belly seems to get stuck. Meow's beard shook and didn't squeak. Visually, so. Wang Feng: They didn't really let Meow try.

". How can the ventilation duct and the air conditioning duct be separated upstairs? Isn't it all downstairs together? It's all together, right? Wang Feng: Do you have any impressions? I don't usually pay much attention. Are there two large air vents in the ceiling downstairs? Wei Hongwei recalled carefully, and only remembered that whether it was a restaurant, a corridor or a room, there was only a square vent the size of A4 paper. The air conditioning winds that are warm in winter and cool in summer are also blown out of these outlets.

Wang Feng shook his head affirmatively. Then suddenly a flash of inspiration exclaimed, "Oops." Isn't there a ventilation duct upstairs? ”

"Huh?" Wei Hongwei shouted in disbelief: "There must be." How could there not be? ”

"Because it's on the ground. It would be nice to open the windows for ventilation. There is no way to do it underground, so you can only set up ventilation ducts to ventilate. Otherwise, the air under the ground will be polluted. ”

The two of them looked up at the bowl-sized air conditioner in the corridor not far away. It's different. It doesn't matter if the shape of the tuyere is square and round, but it is really too bad. Through the air outlet, you can also roughly see the thickness of the pipe inside. The ventilation ducts downstairs are boxy, and even if people go in, it will work if they are crawling advanced. Upstairs, the pipes aren't really much wider than the air outlets. This one is just an air-conditioning system, and the other takes into account the air-conditioning and replacement of the air on more than a dozen floors underground and on the ground, the gap is really too big.

"Wait. It's because you have to ventilate. The underground ventilation duct must also extend to the ground and make an opening in the ground. Otherwise, where will it replace the fresh air......" Wei Hongwei suddenly had a flash of inspiration and exclaimed, "That's right! Didn't we seal the mouth of the pipe to the ground the last time the insects invaded? Where? ”

"You ask me?" Wang Feng glanced at Wei Hongwei and asked, "Am I a water powerhouse?" ”

Wei Hongwei shook his head inexplicably.

"Am I a plant-based powerhouse?" Wang Feng asked again.

Wei Hongwei shook his head inexplicably, and then finally reacted to Wang Feng's meaning. "You're not, I'm ah." ”

"Yes, you are. Do you remember where were those pipes you blocked last time? Wang Feng looked out the door.

Wei Hongwei also looked at the door and said, "Last time, I wasn't in charge of sealing the pipes on the first floor, but ......"

Although I didn't see it with my own eyes, the direction of Shenghui's underground ventilation pipes is still regular.

Meow and Tyson followed Wang Feng and Wei Hongwei to the gate. For the sake of safety, Wang Feng still shrouded everyone in the black vortex.

The two of them didn't go far before they found an air outlet at the base of the wall. And so it was. The ventilation ducts downstairs are not connected to the upper floors, but are directly opened at the foundation of the first floor.

Wei Hongwei pulled the sealed steel bar net, but he didn't pull it. As a result, as soon as the meow steel claws stretched, it scratched the seal off with a loud click. Frightened, Wei Hongwei and Wang Feng hurriedly looked around. Fortunately, there are no zombies in the yard, I just hope that the zombies nearby haven't heard it. Meow is also a little scared after scratching. But it's all scratched. There's no need to worry about how loud it is.

Meow and Tyson poked their heads into the tuyere, but they didn't dare to jump in directly for a while.

"What's wrong?" Wei Hongwei asked Tyson.

"It's so dark inside." Tyson said pitifully.

Wei Hongwei also lay down and looked inside. It's really dark, and the key is that the pipe is still vertically downward. There was some light in the distance. Looking into the depths, it was a black Brun, and I couldn't see anything. I can't see the bottom at all, I don't know how deep it is, it looks terrifying.

"Where's the black boy? Can't it see clearly, too? Wei Hongwei glanced at meow. Isn't the night vision of cats very strong? This is common sense. They can't see, and the meow may be able to see some. But why does Meow look a little scared and afraid to go in?

"Don't be afraid, you two. It is estimated that the distance of the pipe vertically down is one story high. You two are clawing against the wall of the pipe and sliding down, it's fine. Wei Hongwei said. He also pushed Tyson with his hand.

In this way, Tyson subconsciously resisted, and his four paws pushed the ground desperately, exclaiming: "Wow! Don't push it! Don't push! ”

Meow looked in again at this time, and turned back to Tyson: "I'd better go down first." Then it jumped in with its claws.

"Kang!" A crisp muffled sound came, and the two of them looked at it. Good guys, Meow Jump is jumping in. But it didn't slide down at all. It has two front paws, and the claws on its hind feet have not evolved like the front paws. It was also a two-centimeter-long steel claw. As soon as Meow jumped in, her four paws were firmly on the wall of the pipe, and her nails were gone. The meow sticks to the wall of the pipe like a gecko.

"You let go of your claws. Just relax. Relax and slide down. Wei Hongwei shouted to remind meow, and Tyson followed suit.

Meow shrunk the nails of his hind feet first, "Squeak! ”

As soon as the nails of the hind feet retracted, there was a screeching sound on the walls of the pipes. There are two conspicuous marks on the pipe wall, but Meow's hind feet obviously can't pick up the pipe wall. Fortunately, its front paws were not loosened, and its two hind feet kicked a few times in a panic, "Kang! "It plunged into the pipe wall again.

The two of them and one dog broke out in a cold sweat every second. Tyson glanced at Wei Hongwei suspiciously. Slipping down the pipe wall obviously doesn't work.

It is also Shenghui who has invested a lot of money, and the stainless steel pipe wall has not had a trace of rust for so long. The walls of the pipes at the light transmission are glowing with cold light. No matter how you look at it, it's incredibly smooth. The steel plate is also thick enough, and it can still be scratched through thanks to the steel claws.

Wei Hongwei shrank his head when he was stared at by Tyson, and he didn't dare to make any more ideas.

At this time, there was a succession of "Kang!" from the pipeline. Healthy! Healthy! ". The two of them looked at each other and exclaimed, "Good fellow! ”

Meow has faded into the darkness and is no longer visible. But there was a string of holes left in the pipe wall. This kid is also familiar with the road, and he grabbed through the pipe wall all the way and climbed down.

After a while, "Tong! Poof! Meow, Meow couldn't help but exclaim, "Meow! Your sister! ”

"What's wrong?" Tyson knew he was going to jump sooner or later. Meow asked nervously.

"It's fine. You can come down. Not too high. You can try to hold on to the hole I left behind. If you can't catch it, you shouldn't be able to fall to death. "The sound of the meow does not sound far away.

Tyson plucked up his courage and jumped in as soon as he gritted his teeth. It aimed at the hole left by the meow, but it couldn't catch it. Thinking about it, it's so easy to climb down the hole left by the meow step by step. Tyson is a dog. Originally, the weight center of gravity is different from that of a cat.,Even if the nails can pick up the holes left by the meow, it can't help but the weight of its body.。 What's more, the princess tried it at the beginning, and she was also a cat. The step size is not the same. I finally grabbed a hole, and I wanted to continue to stretch my legs downward, but I couldn't land in the next place.

"Poof! Whoa! ”

"Wang! I'm cāo! ”

"Tyson! Tyson, what's wrong with you? Wei Hongwei saw that Tyson fell vertically. It's a lie not to feel distressed, but the sound sounds a little weird when I just meow down. At this time, the sound of Tyson falling down also seemed to be ...... Fell into the water?

"Fluttering...... Bang la la blah! ”

Tyson didn't answer, but it proved Wei Hongwei's guess with practical actions. This voice Wei Hongwei is too familiar, every time he bathes Tyson, he has to shake it violently, and he is also soaked.

"Poof!" Another bang came.

Tyson shouted at Wei Hongwei at this time, "Okay, it's okay." Let's go. ”

"Thank you." Tyson meowed. Tyson didn't think to complain about meow at all, knowing that there was water underneath and not notifying it beforehand.

"No thanks." Meow also accepted Tyson's thanks with peace of mind. It had already vaguely seen that there was a suspicious fluctuation of water light in the ground, and it was reluctant to come down, but it was not the first to come down. One yard to one yard.

In order to facilitate movement, Meow Lao has already taken off all his clothes. Tyson has been following Wei Hongwei and them, and he is still wearing cotton clothes. As soon as it entered the water just now, it shook wildly, and its clothes were still heavy. It tried its best to get the clothes off of it. Fortunately, Meow's claws scratched the clothes as soon as they stretched out. Tyson quickly threw the dress off. It's much easier to shake your body again.

It's just cold. Tyson shuddered and hurriedly followed Meow on.

But the road forward is also very difficult. The further you go inside, the more warm the wind blows, and the less cold it gets. But at the same time, where they landed just now, the water was not deep. The main thing is that the surface is frozen. Meow was actually fine, but when he landed, he forgot to put away his steel claws and grabbed through the ice, and his feet were stained with some water. Tyson fell straight down, smashed through the ice and got into the water. The further this goes, the thinner the ice becomes.

Meow had already put away her steel claws, and the cat's steps were quite light. Tyson is about to move forward one step at a time. It can't see anything, so it can only follow the meow, and one of its unintentional feet falls on the thin ice and has to step on the air to get a body of water.

But as he walked, Tyson broke the jar and broke it. It's all soaking wet anyway, and the water is getting warmer, but it's not so cold. Tyson simply strode forward. And later, in fact, there was only stagnant water, and there was no ice at all. Meow had to drip into the water.

Fortunately, the water is not very deep. It's just that it's just not meowing, and it's not even at Tyson's neck.

"Blackboy, or you can come on my back." Tyson listened as Meow struggled to plop forward in front of him, as if he could really swim.

"Thank you...... Thank you...... No...... I used it. "Midori taught it how to swim, but the teaching facility at that time was just a bathtub, and Meow learned it for a while. Although it looks like a hard time to swim at this time, you can still keep your nose exposed on the water. The main reason is that the paws were too cold when they were dipped in water before, and it was warmer when they entered the water, so Meow declined Tyson's kindness.

Who knows, there are still obstacles ahead.

"No wonder there's stagnant water, no, Tyson, you'd better carry me."

The original insect barrier has not been removed. The stagnant water has seeped out most of it over time, but the plant road is still blocked. Meow fluttered in the water and tried to scratch the plants with her steel claws, but she couldn't use her strength at all, and she choked on two mouthfuls of water for a long time, and she didn't even scratch the plants.

Tyson squatted down, meow couldn't jump in the water, and finally climbed on Tyson's back, and shivered when he came out of the water.

"You stand closer, and I'll scratch the vines apart. One more one, yes, right here. ”

I'm caught! I'm caught! I'm scratching! Scratch......

"Hey, Tyson, Black Boy, how are you doing?" Wei Hongwei's shout came at the right time.

"Master, there is a plant wall here, and the black boy can't catch it, so we can't move forward." Tyson shouted back.

Meow was so tired that she was already lying on Tyson's back and didn't bother to move, depressed listening to the sounds, it seemed that they hadn't gone far.

But no, Tyson walked slowly on the ice, and Meow General didn't run forward with Tyson's speed. After entering the water, the meow fluttered for a long time, and the swimming was half dead tired, but in fact, it did not advance a few meters.

It's swimming with so much effort that it can't catch these plants and vines, right? That's right? At the beginning, those plant-based abilities were also powerful, and these vines were actually stronger than steel plates.

"Fluttering." Meow and Tyson silently watched as the vines slowly retreated on their own, revealing a hole that was not too big for them to get into.

"Can you two get in?" Wei Hongwei's shout came. (To be continued...... ）
