Wu Han, who was in bad luck, saw many disasters. Although he was a veteran like him, he did not mean that others could be as heartless as him.

Xu Yunyun's physique is not very good, and as one of the only two part-time doctors in Peach Blossom Land, she received special treatment and only arranged to do some light work. Now that she was free, Xu Yunyun began to worry about the increasingly unfavorable prospects. She thought of a huge hidden danger, so she reached out and pulled Wu Han and whispered:

"Wu Han, what should I do with the elevator? Will the flood come?"

The original exit of the cave greenhouse is not the observation deck that is about to become a water curtain cave in front of you, but two freight elevators that were forced to be abandoned due to snow. Although foreign beasts cannot invade the cave through the elevator shaft, the flood is different, and water has always been omnipresent. Even though the sealing in the elevator shaft is good, under the impact of huge water pressure and turbulent flow, there is no doubt that the flood will sooner or later flow will flow in from the elevator shaft, which is almost a matter of time. To be honest, before Xu Yunyun reminded him, Wu Han really didn't expect this big loophole. Hearing the sound, he thought seriously for a while, and suddenly smiled, obviously relieved. Then, Wu Han shook his head and said:

"It doesn't matter. Don't worry about that for the time being. Anyway, the terrain on the observation deck is lower. If you really want to flood it, you will flood here first."

After explaining to Xu Yunyun that the reason why the elevator shaft was permeable was irritating, Wu Han’s smile on his face was very bitter. When he turned his head quietly, he let out a low sigh. The wisdom of mortals is always limited, and even if he can’t calculate it, there will always be something he can’t do!

Water-filled mouse caves are a good way to kill rats, but unfortunately, when the survivors of Peach Blossom Land faced this unprecedented flood, their situation was not much better than those small things squeaking in the sewer. The nuclear shelter that penetrated underground and within the mountain for hundreds of meters was once held by Wu Han for infinite hope and regarded as the unbreakable last fortress. Although theoretically, the shelter is enough to withstand direct strikes of millions of tons of nuclear bombs, it cannot solve the threat of floods. Let's take a step back, even if the shelter itself has good waterproof performance, since people are alive, they must breathe! After the ventilation system is submerged, the survivors go down to the shelter with a lower terrain. Isn't that going to seek death?

After thinking for a while, Wu Han seemed to have figured out some joints, and a hint of joy appeared on his face. Suddenly, he snapped his fingers and attracted the attention of people around him, and then Wu Han said:

"Hao Min, Chen Sisi, you two add Li Jue and Wan Qingshi first, and Zhao Yuan. Now let's go in and pack the food and drinking water together. Xu Yunyun and Tan Xiaoyan, you two go to the infirmary to pack the medicines and medical devices, especially the medicines required for water purification. After the organization is done, please inform Hao Min and the others to carry them together. Oh, remember to try to get more daily necessities into the repair room above. How about it, is there any problem?"

After working hard on the front line of flood control for a long time, Zhou Chen's personal image was also in a mess. At this moment, she looked up at the turbulent water outside and said sadly:

"It's useless to leave too many people here, let me go with them!"

Wu Han looked at Zhou Chen without saying a word at first, lowered his head and thought for a while, and shook his head with a wry smile and said:

"Forget it, you all go over! Anyway, there is nothing to do if you stay. Just have me here to watch."

The cave greenhouse penetrates deep into the granite mountain. If you want to rely on natural ventilation to solve the major problem of air exchange, it must be a daydream. For this reason, Taohuayuan has a complete set of ventilation systems with extremely complex structure design and extremely complexity. Boring words like dense spider webs are simply despised by the talent of the unknown perverted designer. The ventilation system used by Taohuayuan is of chaos and complexity that is as chaotic as the capital Xizhimen Overpass.

Without asking, we can tell that those ventilation ducts that make people dizzy and never know what they are for. The ventilation ducts that intertwine each other are not just to meet the ventilation needs of cave greenhouses. I am afraid that their hidden mission is to cover the air exchange system used in underground nuclear masking.

It was a mess, but in order to ensure the daily affairs of the maintenance of this ventilation system pipeline, I don’t know which powerful man spared no effort to dig a repair room from the extremely hard granite layer on the cave greenhouse. When the survivors first moved into the cave, Wu Han had visited the environment to inspect the place, and he had a little understanding of this. The maintenance room was more than 20 meters higher than the cave below, and the internal space was not large. The four walls of the room were densely covered with entrances to various ventilation ducts. At first glance, it looked like a huge beehive. This space in the maintenance room was more than enough for survivors to temporarily live and avoid the threat of floods, but it was basically impossible to live on this for a long time.

First of all, there is no source of food in the maintenance room, nor is there a clean drinking water, and there is nothing but fresh air. Unless the survivors immediately cultivate the ability to eat wind and dew like gods, bringing more food is nothing more than delaying the time and staying hungry.

The fundamental way to survive is to keep the cave greenhouse, and not let the flood destroy the cave. Otherwise, the future of Wu Han and his men would be destined to be a darkness without seeing the dawn.

At this moment, when Wu Han stood on the layered sack sandbags, he swam back at the entrance of the cave, thinking about the feasibility of the plan to forcefully collapse the entrance of the cave to prevent floods. However, after hesitating for a long time, Wu Han regretfully realized that this plan had fatal disadvantages and had to give up this tempting idea. How to accurately control the power of the explosion is definitely a professional skill with extremely difficult conditions. Whether the dosage of the zha medicine is large or small, there will definitely be mistakes.

Instead of being killed by the zha medicine ignited by himself, Wu Han would rather be drowned by a flood. At least no matter how bad the latter is, it would not make people feel frustrated and die with regret!

While Wu Han was alone in front of the flood that was rising and rising, and was about to pass through the dam, the others were not idle. The survivors are now trying their best to strive for a glimmer of hope, but the methods are different.

"Si Si, hand me those cans and buckets."

Hao Min stood beside the temporarily assembled lifting pulley, raised her hand and fixed the box handed over by Chen Sisi to the hook of the pulley, and then she raised her head and shouted loudly:

"Let's go! It's already done."
