Second, it is necessary to expand the establishment of artillery, speed up and expand the production of gunpowder and explosives, and raise the manufacture of gunguns, copper cannons, earth mines, and grenades to the most important position!

The third is to link the water systems wherever they go and to communicate the waters of rivers and lakes as a military important matter, and it must be done! That is, let the Crocodile Legion be with you at any time!

Fourth, step up training and export spies, and try to know oneself and the enemy as much as possible before starting a war!

After determining the principles and policies, Gu Yuan personally led the espionage training class, participated in the training of spies, and was also the head coach of the spy training class, after all, no one knew the significance of this spy, let alone anyone would use it!

During the rigorous training of the spy training class, the Qiu Army Division was ordered by Gu Yuan to command the engineering battalion to dredge and link all the water systems in this area, so that the Dire Crocodile Legion followed.

Gu Yuan called up the distribution map of the neighboring countries that the Divine System Award had given him from his mind, and saw that the closest to the landing of the giant department where they were now was the Night Demon Tribe about 240 miles to the northwest, and they had a demon oar, a powerful demon king possession method."

It was when the two armies were facing each other, their wizard lit a charm, and then put it into the liquid in the stone bowl to burn, and when the blue flames were bubbling in the stone bowl, let their warriors drink it, and after drinking it, the powerful demon king possessed him, this warrior immediately became invincible, and he was not afraid of life and death when he charged, and the sword mountain and the sea of fire could not stop him!

"Hehe! Could it be that the liquid in that stone bowl for the samurai to drink is high-grade wine? Is this really a tribe with boundless demons? If you can make wine, then it is really a demon!" Gu Yuan thought about it, and decided to send a spy to explore the truth.

At this time, the divine system came to inform: "Ding Dong...... If you can send a spy to the night demon tribe, and then get information to find out whether the liquid is high-grade wine, this palace will reward a ventriloquist magic book, learn the barking of beasts, drive away beasts, and control beasts!"

"Really, it's fake, there's no joke in the gentleman's mouth!"

"Hey! A gentleman's word, the horse is hard to chase!"

Gu Yuan carefully studied the geographical location and surrounding environment of this night demon tribe, which was the first step in importing spies. The second step is to send Rou to take people to drive birds to draw, and specially ordered Rou to go in person, only bringing four guards, but bringing a whole giant bird brigade, led by the bird king himself, tens of thousands of giant birds, covering the sun and the earth to protect. In fact, it is to cover up the five of them!

After Gu Yuan sent out scouts, he led the army to advance. As he walked, he connected the big water system, connected the big rivers, lakes and pools, and made his dinosaur army bloom everywhere. In any puddle or stream, you can see the dinosaur dominating the king!

Therefore, this made the march of the Protoss army slow, and it only walked a hundred and ten miles, and all the reconnaissance missions assigned by Gu Yuan had been completed. Rou's topographical map had also been memorized in Gu Yuan's mind, the Night Demon Tribe was about 1,800 people, and the number of combatants should be estimated to be around 1,200.

The nest is located in a tall dense forest with mountains and water on three sides, and the houses under the trees and wooden houses on the trees are lived, and it seems that the tribe is very developed, at least the appearance is very prosperous!

Gu Yuan noticed the mountain behind the Night Demon Tribe, which should be an excellent place for them to retreat and hide. There is also a large forest of trees where they live, which is quite large and directly connected to the mountains. Although the other three bodies of water on three sides are not completely connected, there is not much wide earth and rock separating them, and it is not too difficult for manpower to dig them!

"Rou! What are you doing with such a vague figure on this big tree, like all of you, with a long tail!" Gu Yuan asked curiously and with some appreciation.

"Chief, that's not the same as us! That's a monkey about the same size as us, only a monkey has a tail!" It was this sentence that made Gu Yuan suddenly enlightened, and there was a way to export spies.

The first time I assigned an espionage mission, I had neither experience nor certainty, let alone detailed action guidance. So Gu Yuan was not willing to send Rou in the end, but sent four spies, one man and three women, in spring, summer, autumn and winter. As a tailless monkey, he first went to live in the dense forest of big trees, and then waited for an opportunity to approach the people of the Night Demon Tribe.

It is not a big problem for the people to come, to fly the eaves and walk the walls, to live like apes in the trees and in the woods, not to eat raw meat, but to eat fruits, or the roots of plants. It is not a big problem to communicate with monkeys and live together, and they can adapt quickly.

The most difficult thing to do, and the most difficult difficulty for the agents to overcome, is that they can't communicate in words, and can only fight hand-to-hand to solve daily problems and internal conflicts. That is to say, there is a mistake in the monkey group, which is not solved by quarreling like people, but by biting and seeing blood!

Therefore, the spring, summer, autumn and winter that Gu Yuan is looking for are all special fights, and his heart and character are relatively cold and hard!

"Chief, don't worry! I know us, and I know a little bit about the monkeys, and the four of them can quickly find and merge into the monkeys! I just don't know if they can quickly attract the attention of the Night Demon Tribe! Will those people hunt them for fun? Kill them if they don't meet, right?" asked Rou with a backward face in Gu Yuan's arms.

Gu Yuan smiled: "You don't know as much about people as I do! When you see a tailless person in the group, and they look closer to people than Monkey Jun, that person will definitely be so curious that he will try his best to catch them and not kill them! Curiosity is innate in human beings!"

"Then rest assured!

As soon as he finished talking to Rou about the four spies here, Qiu Junshi hurried over there to report a strange matter. It is not so easy and fast for them to dredge and connect the water system, but often as soon as the construction starts, they do not open their mouths in a few days. Several times they have noticed that where Bai has not dug up, and where he has not dug up, he often opens up by himself at night. It was as if the water had washed away on its own, because there was no trace of excavation. Including the Qiu Junshi and the battalion commander of the stake battalion, they all thought that it was the magic of the leader, and there was God to help!

"Well, God will help me? maybe...... Can't you go and observe in the dark at night?" Gu Yuan didn't believe it, and he wasn't very happy with what they did.

"Chief, we secretly observed and discovered the secret at night, so we came to report to you! It turned out that our own divine soldier water general helped dig it up! The dinosaur army in the water helped the barbarian dragon drive a lot of delicious fish and shrimp from a distance, and after the barbarian dragon group went into the water to eat and drink enough, they used their feet, arched their heads, and hit them with their long necks, and just turned over and pushed away the earth and rocks, so that the water system was connected!"

"Hehehe...... Our dragon team and dinosaur army are worthy of commendation!"

"Prize, chief, what to give them?"
