At the flight speed of the UAV, it reached its destination in less than ten minutes.

When it was confirmed that the target was still there, the UAV began to drop its napalm. With the harsh sound generated when the bomb fell, the mutant mice raised their heads.

Then, there was no napalm. When the napalm was about to fall, it exploded, and a large amount of flammable liquid was scattered everywhere. At the same time, the flame generated by the explosion ignited these liquids.

Centered on the explosion, all buildings within a hundred meters and mutant mice or zombies burned, and the fierce fire ruthlessly burned everything.

Because more than one napalm bomb was carried by the UAV, with the primary school as the center, all buildings within half a kilometer around were affected, and a ruthless fire spread directly.

Now, the rats that just came out to hunt were directly dealt a fatal blow. 80% of the mice were burned on the spot, and the remaining 20% were not much better. With the spread of the fire, the remaining mice were gradually burned by the fire, even if they were contaminated with a little Mars.

Even a small number of mice can't escape bad luck if they hide back in the sewer. The biggest feature of napalm is that they are not afraid of water. Even if the mice return to the sewer, the high temperature of the flame generated by napalm can directly boil the wastewater in the sewer, and then cook the mice.

Although Cai Wenjie's strike directly scrapped more than 90% of the mutant mice, some mice safely avoided the bombing of gasoline bombs and survived.

But at the same time, the explosion of napalm bombs in the city has also caused various problems. For example, the power that was still running normally in this area has been cut off directly, and other infrastructure has been scrapped directly.

Anyway, in a word, this area is completely useless, and a large number of materials disappear with the fire. Although it alleviates the problem of mutant mice, it also means that there are no available resources in this area.

The UAV hovered over the sky several times, confirmed that the target had been completely eliminated, and then began to return to the Xinguang gathering place.

On the other side of the city, Liu Ruyan, who was about to return from the original road, also noticed a fire in the distance. After all, it was difficult to find such a loud explosion and the thick smoke generated when the fire spread.

"Oh, my God! What the hell happened?"

Although Liu Ruyan was shocked by what happened in front of him, he didn't stay where he was, but hurriedly drove back to the direction of the wandering team, wanted to report the situation and decide what to do next.

In fact, it's not just Liu Ruyan. What happened here was also detected by Li Jianjun's Air Force Base at the same time, mainly because Li Jianjun regularly sent reconnaissance aircraft to spy on the city and surrounding areas, and Li Jianjun's reconnaissance aircraft came here a few minutes after the UAV left.

Then he found that there was a fire in this area for no reason. In order to prevent the fire from spreading to other areas, Li Jianjun sent fire-fighting troops to put out the fire immediately after learning the situation.

Of course, the main force of fire fighting is mainly composed of several fire helicopters. A huge bucket is hung under the fire helicopter, and then water is taken from the nearest river and installed in the bucket. The fire helicopter carrying the bucket accurately sprays water on the fire line.

Each fire helicopter can take nearly 3 tons of river water every time, and because the nearest river is less than one kilometer away from the place where the fire occurred, the speed of transporting river water is very fast.

But soon the pilot of the fire helicopter found something wrong, because even if more river water was sprayed on the fire source, the flame would not go out, but it would become more and more intense.

Immediately, the pilot of the fire helicopter reported the situation to his superior.

"Report! These flames cannot be extinguished with ordinary water. I suspect it is the flame generated by napalm. I suggest putting out the fire with a large number of dry powder fire extinguishers!"

"I know, but I can't gather so much dry powder at a time. First, pour all the surrounding buildings with water to prevent the flame from spreading further. After the dry powder is gathered, I'll inform you."

"I see!"

The pilot of the fire helicopter, without saying a word, began to command other fire helicopters to carry out fire prevention operations.

A large number of river water was hung by fire helicopters and drenched on the buildings where there was no fire, and this action was indeed effective. The flames that had already spread were stopped and could not spread out of this area.

However, the same fire helicopter has no way to the occupied areas. This situation will not change until enough dry powder is gathered.

Several fire helicopters returned to the air force base, carried a large amount of dry powder back to the center of the fire, and then spread it. Those flames that were not afraid of a large amount of river water can only put away their magic powers and be put out in front of a large amount of dry powder.

After such a toss, the fire was finally extinguished and the area was saved as much as possible. Although there were no complete buildings, there was still a little left in the end.

Hearing the news that the fire had been extinguished, Li Jianjun also sighed. To tell the truth, those who have the ability to drop napalm in this area don't have two fingers, one is themselves, the other can know without thinking, that is Cai Wenjie, the newly appointed battalion commander.

Li Jianjun does not intend to blame Cai Wenjie. After all, according to his understanding of CAI Wenjie, Cai Wenjie is not a straw bag, but a young man with a sense of responsibility. He does not believe that Cai Wenjie will throw napalm bombs into the city for no reason.

Just as Li Jianjun was silently thinking about how to end, Cai Wenjie's communication came in.

"Chief Li, I miss you so much when I haven't seen you for two days."

"Go, go! You just caused me such a big disaster. What else do you want?"

Although I don't want to blame Cai Wenjie, the education on my mouth can't be left behind.

"You are brave enough to set off a bomb in the city. I dare not do so. Do you know how long it took me to eliminate the fire you just set off? What nonsense"

"Chief, this is your fault. You should be glad I burned that area decisively, otherwise we will not be safe in the future. Take a look at this first."

With that, Cai Wenjie took out the photos he had prepared before. The photos were taken by UAVs before the bombing. The content is also very simple. It is a picture of a large black mutant mouse group gathering in the primary school.

When Li Jianjun saw this photo, he immediately realized the seriousness of the matter.
