The next day, after sorting out the information he had obtained yesterday, Li Ru directly put forward a new idea.

If the burning smoke can really drive away the monsters, then the current pattern will be very different, although from the effect of the smoke, it is impossible to destroy them, but as long as a large area of unexplored areas can be cleared, the materials can be greatly replenished, and many areas that Li Ru originally did not dare to set foot in can go.

The attraction of this idea is great, Li Ru immediately decided to try the experiment of using smoke monsters, if the smoke can really smoke away monsters, then in the future, there is no need to be so desperate to search for materials, and you can simply get a lot of materials, no one really likes to play with life.

Li Ru said just do it, and began to prepare the materials needed to set fire, first of all, the choice of arson point must be upwind, otherwise you can only smoke yourself.

The experimental site chosen by Li Ru is an unexplored square area, with a relatively wide field of vision, due to the large number of monsters, so he has never paid attention to it, and every time he tries to avoid this area, this time it is just in the downwind direction of today, and the right wind direction and the environmental conditions that are convenient for observing the movement of monsters are the most important.

In just a few hours, Li Ru has set up five fires, there are many ways to produce thick smoke, he used the method of covering wet wood, and soon, the smoke began to continue to be generated, slowly spreading to the square area by the wind, Li Ru watched from afar, the emergency retreat route and tools have been prepared, if the smoke instead attracts the monster over, it will not be chaotic, and there is no harm in leaving a way to retreat.

God didn't joke with him, as soon as the smoke came into contact with some of the monsters, it caused the reaction of the monsters that were originally aimless and wandering leisurely, and the monsters that came into contact with the smoke began to move quickly in the direction of moving away, and because the smoke continued to spread, the square that was originally full of monsters soon lost the shadow of monsters, and all the monsters scattered in all directions.

In the limelight of everyone, the experiment was a huge success, and no one would have imagined that such a simple method could play an incredible role.

After that, Li Ru tried to search for materials in a similar way in the next few days, and further confirmed the effect.

Li Ru is not only satisfied with a little material, he set out a large area, mobilized Li Wei and Li Qiulan, in order to expand the scale as much as possible, Li Ru got a large amount of fuel from the fuel tanks of many abandoned cars, in order to create a large area of smoke, for this reason he did not hesitate to set fire to a large block to ensure sufficient scale, the surrounding area fell into a sea of fire and smoke for a while, like a fire hell, if people go crazy, really do anything, Li Ru is a good proof of this.

The smoke smoked away the monsters, and at the same time smoked out individual survivors, most of them were the same as Li Ru before, cowering in a corner of the town, quietly waiting for rescue, this time Li Ru set fire on a large scale, which forced them out, Li Ru used binoculars to occasionally see some survivors who fled in all directions, although he felt a little sorry, but he couldn't help it, the fire came out of control together, spread rapidly, and the fire burned for a whole day and night before gradually stopping.

If you want to put it in the past, I'm afraid you won't be sitting in prison, right? Looking at the dilapidated scene around him that was almost in ruins, Li Ru thought with some self-deprecation, and at the same time felt a little excited in his heart, this kind of thing he couldn't have imagined before, let alone did it.

Li Ru took a weapon alone and tried to start searching the area that he didn't dare to search before, just in case, he still decided to explore the road himself, and if it was really okay, he would bring Li Wei and the others again.

The fire drove away the monsters, and at the same time burned a lot of supplies, Li Ru looked at the various wreckage and felt a little painful, but he believed that he was right, in an area where a large number of monsters gathered like this, he didn't dare to think about it at all, and now he at least dared to come, even if most of them turned into ashes, but there would always be some left, which should be enough for a team of four people.

Li Ru found that although it was ravaged by the fire, some areas were still relatively intact, some high-rise buildings were still intact, and even a large number of corpses were found, all of which were trapped in the building and smoked to death, Li Ru was not sure if there were any survivors in the corpses, maybe he indirectly killed many people, he no longer wanted to think about it, this would only increase the guilt.

Li Ru began to select some large buildings that were not seriously eroded by the fire to explore, and now the material search is still in the first place, although the fire and smoke drove away the monsters, and it is impossible to come back in a short time, but no one can guarantee that they will not revisit the old land in the future, if it is really like that, then I am afraid that I will want to cry without tears, so Li Ru seized the time to collect the materials that were retained, in case the previous efforts were lost.

Li Ru searched layer by layer, due to the fire, it was difficult to distinguish the function of each building from the outside, so he could only search one by one, once he found a large number of materials, he made a mark nearby, he was not naïve enough to move back, his purpose this time was just to explore the way.

Li Ru is currently on the fourth floor, judging from the surrounding environment, this should have been a shopping mall before, although a considerable part of the goods have been destroyed, but there are still a considerable number of scattered things alive, Li Ru also simply checked the situation of the materials, and made a mark after going downstairs.

The rows of shelves made it difficult for Li Ru to search, because there might be monsters that survived, and because he was uncertain about the possible location and number, he didn't dare to attract them out through the sound of tapping as usual, so he could only carefully grope for them step by step.

Bang!

Li Ru was walking between the shelves, and suddenly the things on the shelves in front of him fell, startling him, and he was relieved to see that it was okay, but before this breath was finished, a black human figure in front of him suddenly rushed out, and he was about to swing himself with a stick in his hand, Li Ru has been very comfortable killing monsters these days, and his body has remembered the feeling of assassination, and his brain did not react, so his body made his own action, and the sharp spear head stabbed steadily into the chest.

"Ahh

Will you take a weapon, will you scream? Is it human? Li Ru's heart tightened when he thought of this.

The human figure on the ground was twisting on the ground with his chest clutched, and bright red blood gushed out of his chest, not the kind of viscous plasma, Li Ru basically affirmed that the other party was human.

The sudden situation caught Li Ru a little off guard, and in the blink of an eye, the people on the ground were no longer writhing in pain, motionless, like dead bodies.

Li Ru stepped forward to check in fright, judging from the blood and skin, it was a person, because his appearance was very black, his face was covered with blood stains and dirt, he looked a little hideous, and his breathing and heartbeat had stopped.

After reconfirming, Li Ru knew that he had killed a person by mistake, and his hand holding the spear trembled a little, which was different from the feeling of killing monsters, and he had a strong sense of guilt.

Li Ru knelt beside the corpse, in a daze, the impact was a little big, and he couldn't accept the status quo for a while.

"Damn!" Li Ru tightened the spear in his hand and let out a resentful roar.

Self-blame, guilt, anger and then helplessness, in the end, Li Ru stood up again and bowed to the corpse to express his apology, maybe it was useless, but this was his way of expressing his apology.

Li Ru put the spear aside, dragged the corpse on his back, picked up the spear again, and walked downstairs step by step.

In such an accident, Li Ru also lost the mind to search for materials, and walked slowly towards the community with the corpse on his back with a heavy heart, the corpse was very heavy, but Li Ru felt that his heart was even heavier, and the catastrophe has changed a lot, and he is even ready to kill the evil person he thinks if necessary, but it is difficult for him to convince himself to accept killing an innocent person by mistake.

When he returned to the community, Li Ru did not hide the sins he had committed, he spoke out, found an open grass nearby, dug a pit himself, used it for burial, and finally cut a wooden sign and inserted it in the grave, because he didn't know what his name was, so he didn't write anything, just a simple funeral, which was his atonement for this.
