Code of Wasteland Survival

　　 The situation in the laboratory building seemed to be exactly what Qi Lin had judged. There was no spider king, and the number of servant spiders was far less than that of the teaching building he stormed into for the first time.

　　 all the way up to the second floor, there were only a few sporadic servant spiders. Before they found Qi Lin, they were directly eliminated by Qi Lin.

　　 According to the content marked on the floor plan at the entrance, the chemical laboratory is on the second floor.

　　 Eight chemistry laboratories, Qi Lin directly chose the one closest to the stairs.

The metal door used an old mechanical lock. Qi Lin took out a metal hairpin and easily pried the door lock open-as soon as he opened the door, a disgusting smell came on his face. Accompanied by this smell, there was also a tall human figure, rushing towards Qi Lin at the door.

　　 "Zombie?"

　　 Dark vision easily helped Qi Lin see the face of the figure clearly. It was an "iron-armed zombie" with a tattered white coat.

　　 Iron-armed zombies are the same high-level loss as Swift zombies. As the name suggests, the two arms of iron-armed zombies, due to the relationship between virus and radiation, a large amount of abnormal accumulation of cuticles, become like two thick hammers.

　　 If the swift zombie is a killer who uses high agility to pounce on the weakness of the prey, then the iron wall zombie is a heavy infantry with a strong frontal shock. The two "hammers" are simply the best defensive weapons against heavy armor.

Facing the attack of the iron-armed zombies, Qi Lin flashed through the opponent’s armpit, making this "open door kill" rush to the air, then turned around and grabbed the iron-armed zombies’ necks, hunting with curved blades. The blade of cold light flashed, and the whole head of the zombie was cut off!

　　 "Boom!"

　　 Although Qi Lin supported the corpse of the zombie and also caught the head that fell, but the arms beside the zombie could not take care of it, and the falling arms hit the floor with a loud noise——

　　 "It's over!"

　　 Qi Lin felt cold, this movement, it is estimated that the Assassin Crypt spiders in the whole building can feel it!

　　 However, after three minutes, no servant spider appeared on the second floor, just like the few servant spiders that Qi Lin killed on the first floor were all the Assassin spiders in this experimental building.

If the servant spiders are all attracted by Luo Xiang and the others, it is totally unreasonable. Based on the calculation of at least one thousand servant spiders in a "lest", the total number of servant spiders on the entire campus should be around 7,000 to 8,000, so many. The servant spider, how could it be attracted to Luo Xiang and the others all at once!

　　 This doesn't make sense at all!

　　 But even if Qi Lin feels so weird, the action still has to be carried out as originally planned. Putting the iron-armed corpse aside, closing the door, Qi Lin strode into this old-time chemical laboratory.

　　 This university can only be regarded as a second-rate level in the old days. Naturally, the laboratory cannot be compared with those of Peking University and Tsinghua University. At most, it can play an auxiliary teaching role.

　　 This laboratory is about two hundred square meters. In addition to a large electronic blackboard and a podium table, there are more than a dozen laboratory benches. At the back of the laboratory, there is a row of cabinets for storing chemical reagents.

　　 In addition to the iron-armed zombie, there are also a few corpses in the laboratory that also wear white coats. These corpses should have been the teachers and students of this school during their lifetime. Qi Lin casually inspected the corpses. Half of these people's bones were black, and it was obvious that they died of high-dose radiation. The other half had several comminuted fractures and gnawing marks on their bones. They should have died from the iron. Arm zombies.

　　 Qi Lin didn't have much mood to pay attention to these dead people now. After making sure that there were no living things in the entire laboratory, he began to carefully search for what he needed.

All kinds of glassware, iron stands, alcohol lamps...There are many things on the experimental bench. If these old-age precision instruments can be obtained in Thunder City, they can almost be sold at a good price, especially those in the game. Players who are still addicted to scientific research are absolutely willing to pay big prices for these things.

　　 However, Qi Lin is not here to pick up waste. The space and weight of his backpack also limit Qi Lin's ability to take away only those chemical reagents as the first target.

　　 Anyone with a certain chemical foundation knows that both nitroglycerin and ammonium nitrate are powerful and explosive products, and Qi Lin’s goal this time is the concentrated nitric acid, concentrated sulfuric acid and glycerin commonly found in the laboratory.

　　 Under the catalysis of concentrated sulfuric acid, glycerin will form glycerol trinitrate (also known as nitroglycerin) and water with concentrated nitric acid.

Nitroglycerin is unstable. Once it is hit by a mechanical impact, it will easily explode. Moreover, the same one kilogram of nitroglycerin has 16 times the power of black powder when exploding~www.wuxiaspot.com~ and the famous TNT only has black powder. 14 times.

Many reagents on the experimental platform have been knocked over. It can be seen that there has been a fierce fight here-if there is no third party involved, the two parties in the fight should be the survivor who locked themselves here and that. The iron-armed zombie whose head suddenly changed.

The whole place is full of glass fragments, and the few complete beakers on the experimental platform are also empty-most of the chemical reagents are left unsealed for three years, either volatilized or deteriorated. This is also Qi Lin opened The reason for the disgusting smell behind the door.

This strange smell is not only unpleasant, but also slightly toxic. After Qi Lin stepped into this laboratory, the blood has been slowly losing blood, but due to the existence of the rapid recovery skills, the blood is basically returned immediately after the blood drops. full.

　　 There was nothing Qi Lin wanted on the experimental platform. Qi Lin quickly turned his eyes to the locker at the back of the laboratory, but with only one glance, he couldn't help but curse his mother.

　　 The glass showcases of the lockers were almost all smashed, and the reagent bottles inside were naturally not immune to the disaster——

　　 Angrily kicked the corpse of the iron-armed zombie, Qi Lin angrily exited this laboratory-there are seven others, he didn't believe that there was a destructive zombie hidden in every laboratory.

　　 Qi Lin glanced at the window in the corridor. The movement in the distance was much smaller. It seemed that Luo Xiang and the others left the school as planned after attracting a large number of servant spiders.

It is now 2:15. According to the agreement, Qi Lin still has 15 minutes to collect chemical reagents. At 2:30, Luo Xiang and the others will launch another feint on the nest of the Assassin Crypt Spider. After the cover got the reagent, Qi Lin retreated.
