In the Demon Cult camp, there are countless patrols within a radius of three kilometers. The timing and number of these patrols are irregular, and ordinary spies are bound to be discovered.

Considering that there were many masters in the Demon Sect Formation and the defense was so tight, Qin Shuhuai asked Tang Sanniang to wait outside now, and he and Zhiren went in to investigate first. Although Tang Sanniang's cultivation is good, she has reached the fourth level of Xiaocheng Realm, but she knows that she is nothing in front of the master of the Demon Sect, if the whole operation fails because of herself, then the Tang Sect will be disgraced, so she is not reluctant at all, and listens to Qin Shuhuai's arrangement.

Qin Shuhuai and Zhiren immediately infiltrated the Demon Sect camp, and with their cultivation, in the mountains where there was no shortage of obstacles, they could naturally be unaware.

The two sneaked into the Demon Cult camp, touched around the camp first, and quickly figured out the situation.

First, they found a small stream in this place, which ran directly through the north side of the Demon Cult camp, the stream was not large, but the water was clear.

The river was not shown on the original map, presumably due to the negligence of the mappers, or the geological changes such as earthquakes and landslides that occurred in this area later, so that such a river suddenly appeared.

Since there is this stream, the water source for the Demon Cult soldiers to drink and wash in the north of the camp will definitely be taken here.

Then, they found two clear ponds in the southwest and southeast of the Demon Cult camp, and there was no doubt that these two ponds would become the main source of water for the Demon Cult south of the camp.

In addition, they also found a few wells in the village, but considering that the Demon Sect generally does not harass the people, Qin Shuhuai speculated that they would rather go to the pond to get water than use the well water, so these wells can not be poisoned, which can also reduce the accidental injury of the people. In addition, there are many small pools in the mountains, but their poison is limited, and they can't poison them one by one, so they are lucky to be the demons who drink the water in the pools.

The location of the poisoning has been decided, but the timing of the poisoning will have to be discussed.

Why? Because the creek that runs through the northern part of the Demon Cult camp flows. If the poison is dropped too early, it will flow away in a while. Also, there may be fish in the pond, and the resistance of the fish is definitely worse than that of people, and it takes six hours for a person to have a seizure, and if a fish eats it, will it take half an hour or even less for the fish to have an attack?

Therefore, it is necessary to accurately grasp the time of poisoning.

In addition to the question of time, there is another question, that is, how many people are left in the lower reaches of the river, and if there are many, then the river must not be poisoned, otherwise he cannot afford the consequences.

After coming out of the Demon Sect camp, Qin Shuhuai and Zhiren first investigated along the creek and found that the creek had merged into a valley after a few miles. There shouldn't be many people in the valley, so I was a little relieved.

After the two went back, they found Tang Sanniang.

Qin Shuhuai asked, "Sanniang, if the poison of this 'Thousand Poisons Gu Xuanzhong' is thrown into the water, will the fish die immediately if they eat it?"

Sanniang replied, "Master Zu took this factor into account when designing this poison, so he added some special herbs to the medicine, so that the fish will not die immediately after eating it." However, it will allow the fish to live for an extra hour. ”

Qin Shuhuai thought for a while and said, "An hour should be almost." In that case, we can cast those two ponds before the Demon Cult is about to cook. Then go to the upper reaches of the small river to the north. ”

Jiren agreed.

Qin Shuhuai looked at Tang Sanniang and said, "Sanniang, in this case, I'm afraid I will bother you to go with us." The two of us will open the way in front of us for a while, and you will follow when we are sure it is safe. ”

Tang Sanniang smiled faintly and said, "The poison doesn't look at the master, whoever votes for it is the same." Sanniang is still afraid that you will take this medicine to study? That is too much to treat the alliance leader as the alliance leader. ”

Qin Shuhuai and Zhiren both showed admiration on their faces. The poison of the Tang Gate has never been given to outsiders, although ordinary people can't configure it even if they take the poison, but since this is the treasure of the Tang Gate, naturally it can't be given to people casually, as the old saying goes, just in case?

But this time, in order to fight the Demon Sect, Tang Men was willing to take out the treasure of his own sect, which was also very affectionate.

Tang Sanniang took off a heavy burden on her body and handed it to Qin Shuhuai, and said, "Alliance leader, here are a hundred packs of 'Thousand Poisons and Ten Thousand Gu Xuanzhong', each pack can poison at least a hundred people, according to the size of the pond you just described, each pond only needs to cast twenty packs." As for the stream, you have to calculate the time for it to flow upstream, and then spread it slowly, bag by pack, so that it floats evenly on the surface of the water, and then it will dissolve. The light work under the lower level is not as high as yours, but it is inconvenient to go in, and I am afraid that I will miss a big event, so I will wait for you to come back outside. ”

Qin Shuhuai took the burden, and then said, "In this way, please Sanniang just wait here for good news." ”

Tang Sanniang remembered something again and said, "Alliance leader, wait a minute. ”

As he spoke, he took out a small porcelain bottle from his arms, stuffed it into Qin Shuhuai's hand, and said, "When poisoning, remember to stand upwind, and hold your breath and concentrate, don't smell this poison, don't touch this poison with your hands, and don't inhale this poison." This is the antidote to this poison, in case of an accident, take one pill immediately, and you will be safe. ”

Touching, sucking, and smelling will be poisoned, and it is indeed the world's most strange poison.

Qin Shuhuai took the antidote again and said, "Thank you Sanniang!"

After that, he took Zhiren and quietly infiltrated the camp of the Demon Sect.

The two of them first came to a pond southeast of the Demon Cult camp. The pond is an irregular circle, about sixteen or seventeen meters in diameter. The pond is in the middle of a forest on a hill, and the Demon Sect naturally sent people to see the water source, and protecting the water source is originally common sense in the soldiers.

This pond is guarded by a team of about thirty demon cultists. However, twenty of the thirty were napping and resting, and only ten were on duty, presumably in shifts.

That's a bit of a hassle.

If you kill them or knock them unconscious, the Demon Sect will definitely know that something has happened to the water source, and it will be strange that you can still drink the water here tomorrow!

The only way to do this is to distract them and then poison them quickly.

Qin Shuhuai was about to ask Zhiren what he could do, but he didn't expect Zhiren to say first, "Hehe, brother is optimistic, brother will give you a good show." ”

After saying that, he immediately rushed into the forest.

Qin Shuhuai had no choice but to hide in a tree and wait.

After waiting for about a pillar or two of incense, Zhiren came back quietly, and he was still carrying a wild boar weighing more than 100 pounds on his shoulder. The boar lay quietly on his shoulder, but his stomach was still lying together, apparently unconscious.

Qin Shuhuai understood at a glance and praised, "Brother makes a good means." ”
