Currently, the materials required to upgrade the base to 'gold' are stuck on precious metals.
The three properties of flood prevention, earthquake resistance and wind resistance require a total of 20kg of precious metals.
Precious metals refer to metals containing eight elements: ruthenium, rhodium, palladium, osmium, iridium, and platinum.
The easiest metals to get on the market are gold, silver, and platinum. The rest, such as tin, scandium, iridium, nickel, etc., are mostly used in chemical reaction catalysts, electronic equipment, nuclear fuel rods, and steel production.
Firstly, Shi Man couldn't decompose these things, and secondly, materials like steel and fuel were themselves precious materials!
There are eight gold and jewelry stores on the first floor of the supermarket. Most of these gold and silver jewelry are locked in the store's safe after the accounts are counted on the same day.
After Shi Man dived down, the water was muddy and yellow, which greatly affected his vision.
Fortunately, she was very familiar with the place and had a good sense of direction, so she quickly determined the location of the jewelry store.
Shi Man was lucky. Perhaps because the previous flood was too severe and the water pressure was too strong, the safety glass doors of several houses had been shattered.
After she swam in, she swept through each safe one by one. There was no need to pry open the safes at all. She simply put the safes into the system backpack. The system would extract the necessary supplies from them anyway.
By the time you reach the fifth store, you will have completed the task of obtaining the 20kg of precious metals required for the upgrade.
Shi Man did not stop. Since he was already here, he naturally had to sweep the place thoroughly.
While sweeping, she remotely chose to upgrade the base, and soon, a prompt sound rang in her head.
Ding~ Homestead upgrade completed.
A system panel appeared on the side of her vision.
[Base level: Gold (↑), the next upgrade requires 100,000 points. ]
[Main building strength: Level 4 steel frame (↑). The next upgrade requires 20 tons of steel, 20 tons of cement (already achieved), and 1 ton of precious metals.]
【Storage space: 35,000m³ (↑), water tank capacity: 40 tons (↑), high-efficiency black soil 50㎡ (↑)】
[Flood control: Reached top level, earthquake resistance: 10 (↑), wind resistance: 10 (↑), constant temperature system unlocked, currently: constant temperature: 2 (↑), next upgrade requirements: Pure Land Prosperity 100, Greening value: 100.]
【Power supply time limit: 100 days (↑).】
Ding! Base upgrade mission completed, reward points: 5000. Combat Suit*1, Pistol*1.
——Ding! Daily precious metal collection task, reward 200 points.
The joy of the base upgrade was so great that Shi Man almost fainted when he saw the supplies needed for the next upgrade.
Precious metals... 1 ton?!
What the hell is green value? Does she have to plant trees before her landownership project even begins?
But obviously, the new constant temperature system is very important!
You know, after the flood, there will be extremely cold and hot weather. It can be said that at least 30% of the world's population died from extreme cold and heat.
The temperature dropped to -70 or -80 degrees Celsius, and the whole world was frozen.
After the freezing, the global temperature rose, and the high temperature of 50 or 60 degrees Celsius could directly kill people!
Shi Man felt goosebumps all over her body just recalling that time in her previous life. She was able to survive the extreme cold and heat purely because of her good luck.
After raiding several jewelry stores, Shi Man went upstream. After returning to the escape passage, she put her diving equipment into her system backpack, put on her windbreaker, and changed into combat boots.
She didn't have time to take a closer look at the tactical suit given by the system. She saw a tactical belt inside that could hold a knife. She took it out and tied it around her waist, and inserted the triangular bayonet into her lower back. At the same time, the pistol given by the system could also be placed on the belt.
Shi Man checked the pistol, which was a 92G pistol with a caliber of 5.8 mm and a magazine of 20 rounds.
Shi Man took a deep breath, and the depression about the supplies needed for the next upgrade was swept away.
Suddenly I understand Liu Lili a little bit, she was so excited that she screamed with the electric booster in her hand!
Who can resist the charm of hot weapons!
She put the 92 pistol in the holster on her waist, and covered it with her windbreaker, so no one could see how much stuff she had hidden on her waist.
At the same time, Shi Man took out his mountaineering bag and put it on his back as a cover, put the nail gun in the bag, and walked towards the supermarket with a baseball bat in his hand.
As soon as Shi Man came out of the corridor, she heard some movement outside the escape door. She looked up and saw a man squeezing in carrying an exaggerated flamingo swimming ring.
