It's also thanks to the fact that the people are all supernatural now, and their physique has improved a lot, otherwise I'm afraid that the temperature will freeze as soon as it drops.

"It's too cold."

"yes, I feel like I'm going to drop my ears."

"What now? Everyone's clothes and quilts may not be able to withstand this temperature. ”

"There's always a way, didn't you say you found a lot of sunflowers?"

"The sunflowers haven't been cultivated yet, but now they will attack people, and each tree is five or six meters tall, where do you think we can put it?"

When they went back, they found that the problem had been solved, and there were two more big tree houses on the pine trees.

The two dormitories are equipped with the geothermal function made by Teacher Qi under the command of Li Hua and the metal supernatural person, and the electric blanket that has been eliminated for two or three hundred years has been made a long time ago, so you don't have to worry about freezing to death.

After that, they lived the days of cat winter, of course, it didn't mean that they nested in the room to play the stand-alone game on the bracelet, Liu March took people to cultivate sunflowers on the ground.

Song Yi was not idle except for worrying about the situation at home, and continued to study machinery and formations, both of which must be learned, as long as she studied it, she would have the opportunity to go back.

Occasionally, I will go to Mr. Liu's place to start, but unfortunately now Mr. Liu uses abilities to improve plants, and she can't help much, and her ability to get rid of various instruments seems to be useless.

It's not that Song Yi knows how to gene edit, she has also learned hybridization and other methods of cultivating plants, but she can't use it at this time.

So she still honestly studied her abilities and machines, but half a month later, Ye Lin suddenly called someone to a meeting.

Song Yi walked to the conference hall and found that there were 3 people inside, in addition to Ye Lin and Hechen, there was also the vice principal Zhou Wen.

"Hello Headmaster." Song Yi greeted Zhou Wen first.

"Okay, everyone is here, then let's start, this time I asked you to come over, I want you to help find something." Zhou Wen beckoned Song Yi to sit down, and then spoke.

"Looking for what?" Hechen asked.

"I went to check on the small controllable fusion generator today, and found that there is not much fuel in it, and according to the current consumption, it will last for 8 days at most." Zhou Wen said.

"What, how could it be, didn't we still bring a lot of fuel?" Song Yi was a little surprised, and then quickly reacted: "Is it because of geothermal and electric blankets?" ”

Although they gathered everyone together in order to reduce consumption, the temperature was too low, and now the outdoor temperature has reached more than minus 60 degrees Celsius, so it is very energy-consuming to maintain the indoor temperature in such a situation, even if it is controlled nuclear fusion, it is only small.

"Yes." Zhou Wen nodded.

"So what now?" Song Yi frowned, if there was no geothermal and electric blanket now, everyone would not be able to bear it.

"So I need you to send people to find the school's secret warehouse." Zhou Wen said.

"Secret warehouse? What is that? "The three students were unheard of by this.

"The secret warehouse was set up by the state in response to the catastrophe, and there is one under the thousand-thousand-dollar community in each city, and every school also has it, and there are many important materials in it, such as nutritional biscuits, thermostats, flying skateboards, and controllable nuclear fusion generators and fuel, some science and technology, as well as backup household registration information and literature books." Zhou Wen said.

"The location of this warehouse and the key to unlock it will only be known to school leaders."

After listening to him, the three students were silent, where is this preparation for the catastrophe, it is clearly prepared to preserve the flame of civilization, I am afraid that the country has always been worried that human beings will be extinct like dinosaurs before they have time to get out of the blue star, and retaining the fire of civilization can be regarded as leaving a legacy for mankind.

Of course, if the disaster does not completely wipe out the human race, then these things can be regarded as leaving relief materials for the people after the disaster.

"Where's the warehouse? Can you still find it now? Song Yi asked, such a warehouse location should be relatively deep, and now that it has experienced a major earthquake, I don't know if it can be found.

"You have to try, the secret warehouse is built with special materials, which can withstand a magnitude 10 earthquake and a high temperature of 6,000 degrees." Zhou Wen said.

"Call Dong Yuan." Herson spoke.

"Dong Yuan, his earth-based ability seems to be able to escape to the ground." Ye Lin immediately thought of Dong Yuan and his abilities.

"It's a good ability." Zhou Wen smiled.

"Then it's better to add Li Qin, I remember that her ability is to detect ores." Song Yi thought about it and mentioned it.

"Yes." Ye Lin nodded, Li Qin's ability was indeed suitable, "But she can only detect veins at a depth of 1,500 meters at most." ”

"Give her some crystal nuclei, pile them up, and see if you can go up one level." Song Yi said.

With the ability cultivation method provided by Song Yi, everyone usually directly absorbs the energy in the air for cultivation, and the crystal nuclei are used for emergencies, and the crystal nuclei, except for those left in everyone's hands, half of them have to be paid as group fees.

In the early days, everyone's ability stand-ins were relatively fast, and Song Yi's ability could cheat, but now it's almost level 4, and everyone else is basically level 3.

"Feasible." Ye Lin and Hechen had no opinion, saying that they agreed to take out the common crystal nucleus to help Li Qin improve his abilities.

"Headmaster, can you know where the original secret warehouse is?" Ye Lin asked.

"I can only know a rough idea, and you know, that earthquake wiped out all traces directly." Zhou Wen was also quite helpless.

"It's hard to find." Hechen frowned.

"Why don't you find Mo Han." Song Yi proposed, and the three people who heard it all gave her a thumbs up, which was indeed the correct way for Mo Han to use it.

"Then the three of us, take Li Qin, Mo Han, and Dong Yuan to find the secret warehouse together." Ye Lin clapped the board.

"Plus Warmth and Chen Xia, Zhou Wan, the ability of warmth is to control the temperature, although it can't be used on a large scale, but it is still possible to ensure the temperature of a few of us going out, as for Chen Xia, we are going to move things, we must bring a space ability, Zhou Wan is the strongest attack in the fire system, we will definitely encounter a battle, only Hechen is not enough." Song Yi added a few more people.

"Then add two." Ye Lin has no opinion.

"I'll leave it to you, this is the secret key to the secret storehouse." Zhou Wen took out a piece of paper.

"That's too easy, isn't it?" Seeing the simple word Huaxia on it, the three of them were dumbfounded.
