The moment the crystal sank into the moths, it exploded. When the smoke dissipated, only a thick layer of burnt moths remained on the ground.

Mercury fulminate?

Lu Sheng returned to Sun Tiantian and Xiao Yu and looked at Xu Yi calmly.

Although mercury fulminate crystals are powerful, the crystals are very unstable and can detonate with a little friction or heat.

How could Xu Yi, a school nurse, have mercury fulminate? How dare he carry it around without taking any protective measures?

"Tomorrow I will contact the school affairs office and ask Liu Zihan to move to another floor. Let's clean up the corridor first."

Sensing Lu Sheng's gaze, Xu Yi just smiled lightly and took the lead in leading a few people to clean up the post-war scene.

Sun Tiantian and Xiao Yu were blinded by the phosphorus powder. They didn't see Lu Sheng handling the moth and thought it was all done by Xu Yi.

Lu Sheng just saved the effort of explaining, and after finishing the mess, he excused himself to sleep and went back to the bedroom.

It was past twelve o'clock, and Lu Sheng pressed the sign-in button with familiarity, just in time to receive the 7-day sign-in gift package.

[Sign in for 7 days to start a limited-time mission: drive a rocking car to complete material reserves]

[Limited time: 10 hours]

[Task reward: Base level two security, host’s high temperature resistance properties]

This mission suits Lu Sheng's heart exactly.

The sustained high temperature has greatly increased the load on the power grid, and within a few days there will be widespread power cuts across the country.

In such weather, the rate of food spoilage will also accelerate. With the double debuff of power rationing and spoilage, the existing vegetable and meat reserves in the country will soon be in short supply.

Unbearable hunger will quickly destroy the morality and civilization inherited by mankind for thousands of years. People with red eyes will rush into any place where food can be found, sweeping it away like locusts.

Before most people could react, Lu Sheng took the opportunity to replenish supplies.

After Sun Tiantian and Xiao Yu fell asleep, Lu Sheng left Dingxiang Tower quietly.

Even though it was already nighttime, the outdoor temperature was still over 40 degrees Celsius. The fresh sweat would evaporate quickly, and every pore seemed to be blocked, making it feel stuffy and itchy.

Lu Sheng put on two layers of masks, changed into a black jumpsuit, used medical tape to cover the bright and colorful lights, and carefully stepped on the accelerator.

Fortunately, compared to its exaggerated appearance, the performance of the rocking car is indeed as described in the system.

It is waterproof and resistant to high temperatures, the chassis is very stable, the engine is almost silent, and it is extremely fast. If the appearance was not too outrageous, Lu Sheng would give it ten points.

Lu Sheng drove the rickshaw directly to the largest shopping mall nearby.

These days are the tenth anniversary of the mall, and we have prepared a lot of supplies in conjunction with the food festival.

However, the core power supply line of the shopping mall was damaged by accumulated water in the previous life. By the time the government took over the supply of materials, most of the materials in the warehouse had become corrupted and deteriorated.

Instead of wasting everything, it's better for her to take over.

The security room of the shopping mall was flooded, so Lu Sheng pried open the fire door and the passage was unobstructed.

Because he had worked as a yogurt promoter in a mall's self-operated supermarket before, Lu Sheng knew the location of the mall's warehouse and ran directly to it after entering the door.

In order to cooperate with the store celebration promotion, the warehouse is fully stocked with goods, and Lu Sheng was not polite and opened the door to purchase for 0 yuan.

Normally, bundles of organic vegetables costing tens of yuan a pound are swallowed into the space, and dozens of freezers of grain-fed beef and mutton are taken away with the cabinets.

All fresh imported fruits of various dates are swept into the space, and ice cream, milk, yogurt and snacks and drinks are all packed in whole boxes. As long as you can take away, don't leave anything behind.

It took Lu Sheng three hours to clear out the entire warehouse.

After cleaning the warehouse, Lu Sheng went back to the mall to collect some down jackets and warm pants for winter, and picked out enough toiletries, sheets, quilts and other daily necessities to last for decades.

I also browsed the sports brand section and electrical appliance section for some useful snowmobiles, snowboards, etc., as well as dishwashers, range hoods, integrated steamers and grills, and other electrical appliances that can improve the quality of life.

Lu Sheng also didn’t miss the beauty and skin care products. Mer Helena used baskets to stuff them all into the space. Not to mention wiping on the face, it was enough to wipe the feet with essence every day.

Fortunately, the space is limited only by the plane area, and the vertical space can be superimposed infinitely. Lu Sheng piled the open space in the yard higher than a three-story villa.

Before leaving, Lu Sheng also took away two new electric saws from the decoration area in the corner of the mall.

In close range, the chainsaw is the king of weapons, and it can kill anyone who encounters it.

The time has pointed to four o'clock.

Before dawn, Lu Sheng raced against time to get back to Beijing University and rushed straight to the laboratory building of Beijing University.

Bypassing the long outdoor corridor, Lu Sheng followed the route in his memory and found the experimental greenhouse specialized in agriculture and forestry.

Peking University has an agricultural and forestry research project team supported by the state, and the research results of many graduate and doctoral students will be conducted in the greenhouse for short-term experimental observation.

"Thank you, brothers and sisters, for your graduation design."

Lu Sheng said softly and quickly brought all the cultured seedlings in the greenhouse into the space, along with dozens of barrels of nutrient solution and nutrient soil.

These are the best agricultural plant strains in China developed with a lot of money and manpower. They are many times better than those sold on the market, and many of them are special varieties that have never been seen on the market.

Lu Sheng brought these back to the space to plant them. If normal order can be restored in the future, he could take them out and hand them over to the country. This would not be a waste of research and funding over the years.

After emptying the experimental greenhouse, Lu Sheng rushed all the way to the department director's office on the third floor of the complex building.

In the apocalypse, just hoarding food is not enough. You must also have weapons handy, otherwise you will just be a courier for others, stocking up and waiting for others to lick the package.

Although electric saws are powerful, they are cumbersome to operate and have limitations.

The head of the department is a cold weapon enthusiast. When Lu Sheng helped him clean his office, he saw that he had collected a lot of good stuff, including not only sharpened swords, but also compound crossbows such as the Tianpo RS470, which are listed as contraband in China.

The security in the imperial capital is very strict, and it is almost impossible to obtain firearms at present.

The compound crossbow has extremely strong penetrating power and is even more lethal than a pistol within a range of 50 meters. When used with hunting crossbow arrows, it can easily penetrate body armor and shields.

When the zombie wave arrives in the future, this kind of weapon that can hit the head with one blow will be very important.

Lu Sheng scanned around the department director's office and picked out a Damascus Persian knife and a forged steel dagger in addition to two composite crossbows and some crossbow arrows.

Before leaving, I tried the knife on the dean's desk. Cutting wood was like chopping melons and vegetables, it was extremely sharp.

It was already bright when we left the complex, and the water in the campus had dropped to the calf level.

In order not to attract attention, Lu Sheng simply put away the rocker and walked back to Lilac Tower.

Back in the bedroom, Lu Sheng had changed his clothes and was about to lie down and catch up on some sleep, when suddenly there was a loud noise outside the door.
Chapter completed!
