Everyone looked at Summer curiously, and Summer pointed to the lake and said, "It should be the dry season now, maybe there are too many people gathered in the castle, you see, the water of the lake is much shallower, if we poison it?"

"Poisoned?" Everyone was shocked, and they couldn't help but shiver under the hot sun, this tactic was too ruthless, but everyone quickly became excited, anyway, it was the enemy who was poisoned, and only asked about the result on the battlefield, regardless of the process, as long as the tactics that can kill the enemy, it is a good tactic, it doesn't matter, everyone looked at the summer and smiled.

Only, Leng Yanyin had a cold face, as if she didn't quite agree with Summer's too inhumane tricks.

"Make no mistake about it. Summer explained, "I'm not trying to poison them. “

Leng Yan immediately looked at Xia with a pair of beautiful eyes, and wanted to know what kind of medicine was sold in his gourd.

"I just used a sniper goggle to see a lot of cordyceps growing on the edge of the lake..."

"Medicinal cordyceps?" asked Buckty and Luo Bing in unison.

"Yes, this herb Cordyceps is a laxative herb, we pick these herbs and mash them and throw them into the lake, where the temperature is high, and it can ferment quickly, and people who drink the water here, even if it is boiled, will get sick and have diarrhea...," said Summer.

When everyone heard this, their eyes lit up, and after a moment of cold silence, they said: "This is good, the risk is small, but it takes too long, although this lake is not big, but it is not small, how many herbs do you need to pollute the water source?" I am worried that there will be other variables, is there any other way?"

"It doesn't get any better than this, and as for the time, it won't take one night, you may not have noticed, but there is this kind of grass growing in the nearby hills, and if not, we will take another drastic medicine. Summer said.

"One night?" Leng Yan looked at Summer in surprise, seeing that Summer didn't seem to be targetless, and it was only about one night, so she agreed to come down.

"The terrain here is high, which is convenient for cover, Yanzi, you observe the enemy situation here, provide us with sniper cover, and the remaining four people, put all the supplies here, travel lightly, let's go collect the herb Cordyceps." Summer said, putting down his backpack and sniper rifle, carrying two pistols, a muffler, and two sabers.

At this time, Buckwheat, Luo Bing and Li Zhixian were also ready, and in the summer, they took out the night vision device from the backpack and put it on, vacated the contents of the backpack, and said with the empty backpack: "Everyone be careful, slowly infiltrate it, and act when the opportunity arises." ”

"Look, someone's coming out. Leng Yan suddenly whispered.

Everyone lay down under the hill, carefully probe out to observe, found that more than a dozen people came out of the castle, no one carried two large buckets, lined up towards the lake, not long, these people hit the water towards the castle back, came out fine, when you go in, the inventory is very strict, everyone has to check, you can't get in at all.

Seeing this scene, Xia secretly rejoiced, but fortunately he didn't use the method of infiltration, and whispered: "Dear everyone, let's act!"

When Leng Yan heard this, her eyebrows frowned, and she was not at ease about summer, these four people would do ambiguous things in the dark night, but at the moment of the great enemy, even if she had this worry, it was not easy to say it, not to mention that summer was not her business, what he wanted to do, who he was ambiguous with, she couldn't care at all.

Buckty, Luo Bing and Li Zhixian knew that polluting the water source was the best means of attack, no one dared to be careless, followed behind the summer, towards the lake in a roundabout past, the summer took the lead, took everyone around a big circle, came to the opposite side of the castle, lay on the sand dunes and observed for a while, if you want to get to the lake, you must lie down the sand dunes, the sand dunes are more than 30 meters high, and it is easy to be found directly down, it is not easy to do.

Seeing the sand and dust constantly rolling down by the wind, Summer suddenly had a plan, hugged the gun tightly, turned over to the slope opposite the dune, and lay flat, the back of his body and the sand dune were closely together, because of the steep slope, he slid freely, and it looked like a large piece of sand collapsed from a distance.

Summer slid down the hill, the other three followed suit, everyone smoothly slid down, lying on the sand under the dune, vigilantly looking ahead, motionless, let the wind and sand fascinate the eyes without rubbing, wait for a while, after not finding danger, summer breathed a sigh of relief, suddenly, out of the castle came out of a team of arms, it seemed that there were a lot of people, summer eyes stared, vigilant.

It is not easy to sneak attack the castle of the desert oasis with a wide field of vision, in the absence of heavy weapons and air strikes, it is nothing more than three methods, frontal attack, pretending to be the enemy and silent infiltration, the first two are simply impossible, only one way to infiltrate, but, infiltration needs cover, the surrounding vision is wide, heavy patrols, it is very difficult to infiltrate silently, therefore, the summer chose the water source to work hard.

This method is very time-consuming, but it is also a method, but when I slipped down the sand dunes in the summer and was about to climb to the lake to collect the herb Cordyceps, I saw a team of government troops suddenly coming out of the castle, and I couldn't help but be startled, and quickly signaled everyone to lie down on the spot, under the camouflage of the desert gilly suit, the distance is far away, but there is no need to worry about safety, but you can't move.

After a while, Xia found out that this was a team that came to change the guard, and couldn't help but breathe a sigh of relief, waited quietly for a few minutes, and after making sure that the other party didn't find out, he said in a low voice: "Brothers, three hundred meters ahead is a lake, everyone be careful to disperse, slowly climb over, our night vision device has infrared thermal imaging function, can be higher than 0C target heat sensing, it is not difficult to find the medicinal cordyceps, action." ”

The night vision device we wear is a military product of the Erdan government army, it is the victory of Obar's previous battles, with a photon light source, infrared heat source, and radio farsightedness, and can automatically detect how many meters the distance of visual vision, but also set the direction, and the most powerful thing is that there is no difference between the inside and the outside and the dawn, but from the outside of the lens, there is no digital display, no indicator light, this kind of night vision device is bought from a developed country, and the performance is naturally the best.

"Understood. With the help of night vision devices, the surrounding situation was clear at a glance, and everyone could see clearly what plants grew by the lake, and they pulled out their sabers.

In the summer, he picked a medicinal cordyceps and put it in front of the three of them, saying: "This is the medicinal cordyceps, everyone hurry up, the more you pick, the better!"

Luo Bing and Li Zhixian nodded when they saw it, Buck Buck pretended not to see clearly, and followed behind Summer, when the two of them distanced themselves from Luo Bing and Li Zhixian, Buck Ty pounced on her and pressed Summer under her.

"What are you doing? Why don't you go get the medicine yet!" said Summer in a low voice.

"I'll pick something else first. Buckwheat grinned and immediately attacked Summer...
