The Qiu Junshi also came over to echo, it should be like this, safety first!

By the time they turned their faces to look at the flock of giant birds and the Monkey Secret Service Team that had landed on the beach, Mrs. Rou was already holding a thin skin in her hand and walking towards Gu Yuan with a smile.

"Rou is prescient! She must be holding the topographical map of the island!"

Mrs. Rou took a look at the thin cowhide, and the topography and landform of the island drawn with plant juice were very clear. The island is roughly oval in shape, with a small but large hill in the middle, the top of which is bald, and there are layers of plants around it, tall broad-leaved trees, low fruit trees, and large fruit trees painted on them! Then there's the sandy beach, a slick patch.

Gu Yuan looked at the cowhide map while holding up the telescope to look at the center of the island, although the slope of the mountain in the middle was very large, and the vegetation was really distinct. Under the tall broad-leaved forest, there are groups of wooden houses, people lying in the fruit groves and on the grass, and there seem to be many corpses of birds, all of which are lying on the ground, especially the birds with their beaks stuck in the grass on the ground.

"It's so complete, it's so clear! It seems that there are no living people on the island anymore, and there are not even many birds, right?" Gu Yuan asked softly.

"Yes, Chief!"

"Is there not a stream, and there is not a puddle?"

"No! We circled the island twice, and we really didn't see anything! By the way, Chief! We saw that the central hill of the island was black, and the beach on the waterfront half of the island was white, and it was dazzling white!"

"White?dazzling?...... It can't be sea salt, right? The sand here is not dazzling! Let's go over there and have a look!" Gu Yuan led a large army into the central part of the island, because the horses did not come, and it was difficult for people to walk, and it was slow. Gu Yuan ordered to sit on the brute dragon, cross the beach, and go around the grass.

There were no human or bird carcasses on the beach, but a short walk on the grass was visible. It really looks like a soft drawing! Most of the people and birds die in the grass on the ground! When they get around that side, the color of the beach suddenly changes and becomes white and bright!

Gu Yuan got down and squatted on the ground to take a look, sure enough, it was high tide and low tide, and the sea salt left on the beach was dried by the sun, and the sea salt was quite delicate, not as coarse as the sea salt of later generations! Gu Yuan was happy for a while! At the same time, he remembered the things brought by the fifteen big ships that were intercepted, "Could it be that this Bird Island tribesman exchanged the iron ore and rice from the outside with sea salt? If this is the case, wouldn't the ground scouts sent to reconnoiter be in danger of encountering other tribes?"

Gu Yuan didn't show the thoughts in his heart to anyone, because he suddenly remembered that the situation in front of him was not like the people of this tribe knew how to dry sea salt, at least they didn't dig a salt pond, only a thin layer on the beach, it was impossible to exchange it for things, first, it couldn't be collected, and second, even if it was collected, it would carry sand grains.

At this time, I saw clearly in front of those chimney-like things, which turned out to be smelting kilns and foundry workshops. The scale of this place for manufacturing weapons and tools is not large! Gu Yuan walked in and took a look, the technology was indeed good, enough to be comparable to the smelting and casting of his god clan!

"Labor and capital are the technology brought from tens of thousands of years later, isn't this tens of thousands of years beyond the primitive people of the same period?

So Gu Yuan's army scattered to search, and there was no one living from the Bird Island tribe, and there was no flock of birds. Put the dragons on the beach and grass to rest, and you can also look for some bird carcasses to eat. After that, Gu Yuan personally took the lead in climbing up, and the hillside was not difficult to climb, but it was difficult to meet the trees, and he went around and around.

There are quite a lot of fruit trees here, and they are all common in the mountains, and there are not many special fruits, but the fruits here are not very tasty, not sweet!

In ancient distance, they saw the habitat of the Bird Island tribe drawn by Rou, and the grass and wood houses under the broad-leaved trees, clustered in the east and a pile in the west.

"Chief, there are a lot of people in this tribe! There must be thousands of people living here?"

Listening to the mountain man's words, Gu Yuan didn't answer, Qiu Junshi said, "But there aren't many people who die here! No more than five hundred people at most!" In fact, Gu Yuan was thinking about this question, where are the other ordinary people? If there is no island, it should be outside the island, so there will only be a place for big ships to come outside the island.

Gu Yuan decided to open up this island into a military base of the Protoss, first dig up the salt pond, and now the salt is no stranger to the Protoss, they have already dug the land salt mine, and they have also dried the lake salt, at this time, the sea salt is dry, it is fast and good, and it is very easy to scale up!

"Chief, our Flying Ant Legion is not suitable to live on this island for a long time! we must hurry up and get away!" Lady Rou reminded Gu Yuan loudly. Gu Yuan immediately thought of another way, no longer using dinosaurs to transport flying ants, using big ships, fifteen big ships to transport all the flying ants out of the island!

Gu Yuan commanded to the mountains and forests in the middle of the island: "The Flying Ant Legion obeys the order! Fly low to the big ship on the edge of the island, leave this island, and go to the vicinity to find ore and eat your stomach!"

The reason why the flying ants are ordered to fly low is because the sea breeze here is still very strong, and as long as the flying ants fly higher than the treetops, they will be blown into the sea immediately!

The flying ants were transported away first, and then the two battalions of the Divine Guard Army were left here to dry sea salt, smelt iron and cast, and leave more than half of the giant birds to breed here. Then there is no need for the dinosaur army that is already in the sea, they are free to go back and forth between the sea and the river!

"Report to the chief, what should we do if we find a lot of bird eggs in the trees, in the soil holes on the mountainside, in the crevices in the rocks, and in the grass on the island?"

Hearing the scout's report, Gu Yuan's eyes lit up, and he turned around and asked the Bird King, "Can you hatch these birds and raise them?"

The Bird King nodded solemnly.

"So, if you raise these birds, will they be subject to me in your flock?"

The Bird King nodded.

Because there are many species of birds in the giant flock, it is basically possible to find new parents for the eggs here, just like the children in a human orphanage are adopted. This will add a lot of new members to the flock of giant birds!

Gu Yuan led the army out of the island by boat or on a brute dragon and came to the shore, where it now stopped at the mouth of the river. Sail the big boat into the course of the river and prepare to enter the middle and upper reaches of the river together.
