"The first is to expand the territory, and now there are cavalry troops, within a radius of 50 miles, and they can soon patrol again. The second is to look for saltpeter and sulfur to prepare gunpowder. Gu Yuan thought about it and summoned five company commanders and the old man to discuss the patrol, and they all thought that it was feasible, but there were few people and they couldn't be dispersed to garrison.

"Don't you need people to garrison the frontier first! After demarcation, send out a group of brute dragons and giant birds to defend the border!" In the end, it was Gu Yuan's idea to send out a hundred brute dragons and one hundred and fifty giant birds from each of the four directions to defend it. The cavalry detachment went to patrol regularly and irregularly, and if there was anything, the giant bird could also come and go in time to communicate.

"Old man Dao, at the border, what sign should we erect?" Gu Yuan asked a key question, unlike the current state-owned border card, which can be understood by engrave the words. Maybe the stone is small, and the people who come have a lot of power think it is a sacred stone, and they will move back to the tribe as a "totem stone" to worship it!

The old man thought for a while and said, "Erect an animal skeleton on the border of the four directions, the bigger the better, and then set up a bamboo pole to hang a skull!"

"This ...... Okay?" asked Gu Yuan suspiciously. He was thinking, the tribal boundaries used skeletons and skulls to tell other people of the same kind, "This place is occupied by labor and capital! No one else is allowed to enter! Something is waiting!"

"Chief, this is the only way to suppress the people from other tribes!"

Okay! Use big animals to scare people! No matter how big the skeleton is, can it still eat people when it dies? Therefore, Gu Yuan handed over this matter to the old man with the knife to take charge of it! Brute dragons who died of old age and disease also happened from time to time, and skeletons were everywhere. Human skulls are just as easy to find!

Of course, for the first frontier patrol, Gu Yuan personally led the team. The plan to put a hundred brute dragons and about 200 giant birds in one direction was actually broken in the west of the first stop. The western outpost was placed on the outside of Caishan, and after the old man led people to put the prepared dragon skeleton and human skull, when the bird king sent down two hundred giant birds, there were still hundreds of birds who volunteered to stay here, because it was so beautiful here. A hundred brute dragons are also very happy, temporarily change the plan, Shui and Yun They also came to suggest that Gu Yuan put a hundred more brute dragons here!

Ore is the most precious treasure! What if someone who knows the goods steals it?

Gu Yuan looked at the outside of Caishan, that is, to the west, and was in a good mood, nodded in agreement, and put down the hundred brute dragons and two hundred giant birds that were ready to be released in the south. In other words, the defenders here are 200 brute dragons and more than 400 giant birds.

The west side of Caishan Mountain is a swamp with no edge in sight, extending from the foot of Caishan Mountain to the swamp, there are dense aquatic plants, the ground is shallow water cover, this is a paradise for animals and plants, especially water pine, cress, water birds, dinosaurs and ichthyosaurs.

Gu Yuan wanted to see farther away, what was in the depths of the marsh, and in the telescope he saw tall ryegrass and alfalfa, and most conspicuously the tall reeds and sweet elephant grass that grew as tall as a tree. "Where there are reeds, isn't there a place where there are no grass that can weave grass mats?" Gu Yuan walked a little higher and raised his telescope to look carefully, and finally let him find it, first sporadically mixed in the middle of the reeds, and then after extending for 100 meters, there was a large square area of nearly 100 acres of grass grass! And on the side of the grass pond, there was a road half a foot above the water, which should not be a road, but a ridge.

"Haha! The next time you come to transport ore, you must bring more cattle and trailers, and at the same time transport the ore, you will also transport all the reeds!" Gu Yuan thought about it and observed, there were many beavers the size of domestic pigs in the swamp, fat, round, and shiny brown fur, which appeared and disappeared in the water and grass. This is just enough to enrich the food of the brute dragon herd, but I don't know if there is a quagmire in this swamp? It's the kind of mud that is not deep to the bottom, people and big animals can't go in, once they get in, they will sink and can't get out, that's fatal!

However, look at the reeds and grass ponds, this swamp should have a bottom, that is, there is hard ground, and people can pass by!

After arranging the barbarian dragons and giant birds on the border, and the light cavalry team of sixty people from Guyuan, he went back to take the brute dragons and birds and went to the south again. The southern outpost is located on the Triangle Island, the original home of the Grass Tribe. Although it is relatively secluded, it is not easy for humans to get to the island. But this is where the salt ponds are located, and the most important thing is this!

He also left behind 200 brute dragons and 400 giant birds! The old man crossed the river and put the skeleton of the brute dragon and the human skeleton on the south bank of the big river in the south of the triangle island, that is to say, the entire triangle island and the surrounding waters are the territory of the god tribe.

The eastern outpost was placed on a densely wooded hill in the Black Forest, and at the foot of the hill to the west of the mountain was an open-pit coal mine, a large black pit. The trees here are sparse and tall, so the brute dragons can also enter the forest, but it is inconvenient to run, and they can't run fast at all. Anyway, the running speed of the brute dragon is not fast in the grassland, so just shake its head and tail and live a free life in the Black Forest!

Because there is coal, this is also a treasure, so two hundred brute dragons and four hundred giant birds are also laid.

The northern outpost was naturally located on the hill where the homes of the original bamboo tribe were located, and the birds roosted in the woods and bamboo forests, and the brute dragons rested on the grass by the pond. There is nothing to be particularly protected here, and even the orchard has become a canteen and nap place for the birds.

It's time to transport ore again, and Gu Yuan is ready to harvest the reeds in advance. Bring twice as much as the convoy, and bring all the hook and sickle guns, the hook and sickle on the hook and sickle can be used as a sickle, because the gun is long, and the harvest is puffy reeds, people don't have to bend down, and they are less tired!

The pampas weeds were pulled and piled up, and Gu Yuan ordered people to spread them out and continue to dry them, although they were also dry.

"Chief, what is this? What's the use? Is it not right...... This doesn't look like firewood burns for as long!" the old man and the peasant leader all asked. Gu Yuan explained to them that it was called pu reed, which was pu grass and reeds, which could be woven into grass mats, and people would be warm and comfortable lying on them!

Naturally, no one believed it, because after all, none of them had ever seen such a thing!

Gu Yuan called the peasant leader, and the members of his group, while weaving the cattail mats, explained to them. It is to tie up two horse's legs on the ground, with a log or bamboo pole in the middle, and Gu Yuan is a bamboo pole horizontally.

Tie several thin rattan or fine hemp ropes to the bamboo poles, then tie a stone to each rope, bring a small tuft of pampas reeds, tie them with ropes, and then bring a small tufts of pampas reeds, and then tie them with ropes, and weave them like this, and soon, a large straw mat is completed.

"Wow - the leader has cast the immortal spell again, this is the soft and warm grass that can't freeze us no matter how cold it is!

"This is for sleeping? This ...... The thatch saved in this way can be used to feed cattle, horses and sheep!"
