These black liquids slashed an arc of death in the air, spitting out a distance of more than fifty meters and flying towards Liu Qian on the roof of the car. This is a large-area group attack, almost covering a nearby area of more than ten meters. However, the speed at which the black liquid was sprayed out was not very fast, and the angle of the spray was relatively high, and it flew in the air for seven or eight seconds from the time it was sprayed to the time it landed in front of Liu Gan.

Such a long time was enough for Liu Qian to quickly escape from the attack range of the liquid, and the black liquid that spit out fell on the bridge deck not far in front of him, making a sizzling sound and an extremely unpleasant smell, and at the same time, the concrete of the bridge deck was also burned out of some small potholes, forming small liquid pits, but the bridge deck was not quickly burned through or something.

Whether it is a strong acidic liquid or a strong alkaline liquid, or another unknown corrosive liquid with non-strong acid and strong alkaline properties, it seems that it is still much less corrosive to concrete. But once the player is sprayed, the body will definitely be severely burned, and even the extremely powerful biochemical materials on the galaxy are not immune to this.

And the most terrifying thing is that this mutant zombie spits liquid very far, can reach fifty or sixty meters, plus it has so many spray holes on its body, if these spray holes spray black liquid together, it will form a face-like attack. The player and the survivors are trapped on the bridge deck and can only approach it from one direction, and are blocked by the black liquid, which makes it unable to effectively kill it.

And what's even more troublesome is that this mutant zombie has a hard bone shell, and Liu Qian estimates that this shell should be quite hard and super corrosion-resistant. Plus it's very weak in action. So when it is in a non-attacking state and does not open the mussel shell. Physical attacks of a general nature may make it difficult to deal effective damage to it.

But when it opens its shell, the nozzle inside looks so fragile that a grenade should blow it up if you throw it in. The problem is that Liu Qian can't get close to it at all, and besides, after the grenade pulls the tab, it can't be detonated at a distance of more than fifty meters in the air, right? At that time, the accuracy of the throw will also be in question.

Liu Qian didn't know if the fog armor outside his body could withstand the corrosion of this black liquid, but given that these black liquids were so dangerous. And once it adheres to his body, it will continue to cause damage to his body, so he doesn't want to risk his own life to do this experiment.

Looking back at the several bamboo spears that one of the survivors was carrying, Liu Qian suddenly had some thoughts in his heart. In order to verify this idea, Liu Qian quickly rushed to the area where the black liquid had fallen just now, and held his breath to pull the special rope in his backpack that he had obtained from the biochemical laboratory of the Three Domains Company and stuffed it into the black liquid accumulated in the hole in the ground.

The rope was also extremely corroded in the black liquid, but this biochemical material was really strong, and after being put into the black liquid for a few seconds, it was only corroded by about a third, which made Liu Qian couldn't help but be overjoyed. It seems that his idea is indeed very feasible.

Whatever you have in mind, you have to act as soon as possible. Otherwise, this half of the bridge will collapse at some point. Once this half of the bridge collapsed, no matter what good ideas he had, it would be in vain.

The survivor with a few bamboo spears on his back was named Zhang Hua, who was the owner of a shop near the hospital before the disaster. Liu Qian asked him for a bamboo spear, then found a strip of cloth and tied a stone to the front of the bamboo spear, and tried to throw it at a car fifty meters behind him.

It's a pity that the accuracy is too poor, although Liu Gan's arm strength is very strong, and it is no problem to throw this bamboo spear tied with stones for fifty meters, or even hundreds of meters, but he has never practiced throwing spear weapons before, and he has deviated from the target vehicle a long distance after three consecutive attempts, and once he even flew into the river.

After receiving Liu Gan's order, Yinhe ran over quickly and picked up the two bamboo spears that Liu Qian shot on the bridge deck.

"Master Liu, what do you want to do?" Zhang Hua, the shopkeeper, walked over and asked Liu Qian.

"I wanted to see if I could hit the front window of that car with this modified spear accurately, and it was the one, the red one." Liu Qian replied to Zhang Hua.

"Master Liu, let me try it." Zhang Hua took the bamboo spear in Liu Gan's hand, because the front end was tied to a stone, he was a little uncomfortable holding it in his hand, so he tried it twice in a close place, and after finding the feeling, he retreated more than ten meters, and then rushed forward, the bamboo spear with the stone in his hand flew out of his hand, crossed a precise arc in the air, and slammed into the front window of the red target car more than fifty meters away!

"Holy! There's a way! Liu Qian couldn't help but be very happy when he saw this scene, he wanted to kill the mutant zombie, the difference was the accuracy of long-range throwing, he didn't expect this survivor Zhang Hua's bamboo spear to be thrown so accurately.

"What does Liu Ye want to do?" Zhang Hua still had a confused expression, and the others also looked at Liu Qian, not knowing what he was busy with.

"Can you guarantee that this throw hits the target every time? We want to leave this bridge and live, and it may be on top of yours. Liu Qian confirmed to Zhang Hua.

"Before I retired from the provincial track and field team, I was a javelin thrower, although the results were not very good, but I practiced a unique skill in my more than ten years of practicing javelin, that is, 90 percent of the javelin thrown within a few tens of meters can hit the target; Seventy percent of the target can be hit within 100 meters. After the end of the world, my physical fitness and vision are much stronger than before, and at a distance of about 50 meters, I think I can at least achieve a 95% hit rate! Zhang Hua said to Liu Qian with some pride.

"Very good, you come with me, we don't have much time, I'll talk to you as we go." Liu Qian took Zhang Hua and walked in the direction of the bridge, and after walking a few steps, he turned around and called Zhang Shengli over.

"The others followed us twenty meters away, and after receiving my orders, they continued on their way." Liu Qian said to the others.

"Master Liu, he can't do it." A player pointed to the eighteen- or nine-year-old injured player and talked to Liu Gan. At this time, the bones on his body had been corroded by the black liquid and turned black and rotten, and the whole person seemed to be silent.

"That's also something that can't be helped, who let him run around? When I don't let you do anything in the future, don't mess around, otherwise I won't be able to protect you if I want to. Liu Qian replied to the player, and at the same time glanced at the other players who were running away disobediently just now. (To be continued......)
