"What do they like best? Aren't they eating fresh meat? Nothing else attracts them!"

"Oh, I see, Chief, give the brute dragons and dinosaurs all the prizes we got from the giant tribe, rhinoceros, wildebeests, great anteaters, etc., anyway, it's useless for us to keep them!"

It's really the right thing to let the Qiu Junshi give! That's what Gu Yuan planned!

After rewarding the brute dragon and the dinosaur, when the army approached the outer waters of the night demon tribe, Gu Yuan thought of first ordering the brute dragon to open up the waterway leading to the three major bodies of water at night, release the dinosaur over, and then the two would cooperate to connect the three originally disconnected waters into one!

Ground and air scouts were sent out, but soon returned. Gu Yuan was stunned for a while! He knew that he must have encountered some particularly tricky problem! The agent hadn't sent any information yet, and this scout was blocked again, it seemed that this night demon tribe was not easy to deal with!

Sure enough, Battalion Commander Yun led a few scouts to come, and there were scout soldiers coughing. Before they could speak, the Birds arrived and fell, and the Monkey Agents were coughing. There are also giant birds with their mouths open and anxious to find water to drink, as if they are a little out of breath.

"Report to the leader! This tribe of night demons is really a bit demonic! The sky above their dwelling ground is filled with smoke, as if night is falling, and they can't see anything in their lair from the sky or from the periphery of the ground! Whether they live in a tree house or a grass hut, they don't know what the environment is! Because they can't see it at all!

The most terrible thing is that they use smoke as a weapon! There is a smell in the smoke that covers their old nest, which is spicy to the eyes and choking on the throat, and it makes people extremely uncomfortable! It is not fatal, it suffocates people, and it also makes people suffocated, cough, unable to open their eyes, and unable to move an inch!"

"People and giant birds are like this, what about our Yak agent spies? Have you encountered them?" Hearing Camp Commander Yun and the others, Gu Yuan's first thought was how could the four spies survive this in spring, summer, autumn and winter?

"They were in a lot of pain when they first got there, but now they have a good old monkey from the group of monkeys who gave them a kind of grass...... That's it, chief! Look! With it on your body, the smell of smoke doesn't spicy your eyes or chokes your throat!

Gu Yuan took it from the Yun battalion commander, and it looked like oxtail grass, but it was not oxtail grass, and oxtail grass did not have such a strong sweet smell!

"Do you guys feel the smell of chili peppers we've eaten?" Gu Yuan asked the soldiers who went to reconnoitre.

"Chili pepper?...... Yes, like a chief, it smells too much like chili peppers...... However, the chili pepper is spicy but not choking!"

"Dried chili powder plus one thing chokes on your throat!"

"Chief, birds can't go, and dragons can't go! It's better to send flying ants over to take a look! If you can, launch an extinction attack!" said Qiu Junshi through gritted teeth.

Gu Yuan nodded, and then ordered the Vajra Flying Ant to come! However, it must be tentative first, it must be just in case, after all, this flying ant also opens its eyes to see things and breathes, their eyes and throats are not strong, and if they suffer a little damage from light and smell, poison and heat, it will be a catastrophe!

Send a group of dozens of flying ants, clearly tell them that they are tempting, get closer, as long as you feel discomfort in your eyes and throat, return immediately, and you are not allowed to stay for a moment!

After a while, the group of flying ants returned, and there was still more than half of them left!

"What about the dozen?" Gu Yuan personally designated them to go, and repeatedly told them that it was a temptation, so at a glance, he knew that there were not many who came back.

The flying ants couldn't answer, but two more rolled on the ground and didn't move!

"Ahh

Others are still against it, but they still can't oppose it.

"Chief, go find this grass first, and let the giant birds all pick up one and then go!"

It didn't take long, and they really let the Qiu Junshi find a big bundle. This kind of smoked grass is very luxuriant in this place! Gu Yuan led the four guards to ride the Bird King and his four guard birds, and flew towards the location of the Night Demon Tribe under the cover of thousands of giant birds. Everyone has a grass in their hands, and birds have a grass in their beaks!

When I arrived at the smoky place, it seemed that it should be a mountain ridge, with three lakes of different sizes on the east, west, and south sides, which had been connected into a large lake by the cooperation of the brute dragon group and the dinosaur group. To the north is a large mountain with a series of peaks that stretches far to the north.

Gu Yuan determined that it was the smoke and smell formed by the burning of chili noodles and smoked grass by firewood.

"Do the people of the Night Demon Tribe know that our Protoss has a flock of giant birds and an army of Vajra Flying Ants? This trick is a great way to kill one stone! Smoke can hide their whereabouts, smell can expose humans to themselves, and fire and smoke, spicy and choking can stop many animals, including brute beasts!"

Gu Yuan wasn't sure if they really knew if the Protoss had giant birds and flying ants, anyway, this smoke and smell effectively stopped the attacks of giant birds and flying ants!

The brute dragon can't go, and the dinosaur can't use it, so what should we do? Gu Yuan ordered to wait in concealment! Wait for the intelligence of the four spies! However, the original preset method of delivering information is basically invalid, and it is no longer useful! What should I do if I use a bird to send a message, but now that the bird can't get closer?

"Use the monkeys to pass between the monkeys and the monkeys!" This is the second set of ancient methods of transmitting information! Now the monkeys can get close to the smoke with that kind of smoke, and they can mingle with the monkeys.

Gu Yuan instructed Rou that whenever he sent the Yu agents out to carry out a mission, he would take the trouble to tell the Yu people that they must make good use of the monkey group, not to migrate away, and not to be hunted down and killed by the night demon tribe!

In fact, it was easy for the Monkey Agents to stay in the monkey pack, as long as they no longer wore leather vests and no longer carried bows and swords. However, it is not so easy to influence this group of big monkeys to be reluctant to migrate to other places! Gu Yuan thought of a trick, and from time to time sent agents to bring some food, of course, all of them are what monkeys like to eat, mainly fruits, and there are also individual grains and foods!

"Chief, those poisonous smoke of the Night Demon Tribe should have been done for the sake of hiding their whereabouts and hiding their dwellings! It was not prepared for war! Therefore, it was purely an accident to be able to kill the flying ants and stop the attack of the giant birds!"

Rou happened to come out at this time, Gu Yuan thought of it, but he didn't have time to come up with a correct guess!
