Judging from their uniform modern human clothes, it is not very long before the sea tribe people have the habit of wearing clothes, otherwise they should be able to see the sea tribe's own characteristic clothes, or human clothing hundreds of years ago.

It can also be seen from their goods that there are many stalls of the sea tribe here, but the things sold are very monotonous, clothes, wine, food are the most, there are also a lot of exquisite cups and wine bottles, and there are some cold weapons such as swords and daggers, and the others are batteries and lamps.

These things are very practical, so they will be welcomed here, and more goods in human society, as well as those luxury goods, are not applicable here, and they will not appear. It seems that the Sea Clan has not been in business for a long time, and now it is only the embryonic state of commerce, it is because of the interaction with humans that it will bring a leap, and Elder Shenglin is the leader of the changes of the Sea Clan.

With the heart to go ashore and compete for ambition, they began to guide the sea tribe to learn from humans, which of course started with food and clothing.

Fortunately, there are many treasures under the sea, and they can easily obtain antiques that humans like from ancient shipwrecks, and there is no shortage of treasures to trade with humans. Elder Shenglin used these as capital to make human Tianjiao make money for them.

Zhang Yi noticed that the items they used to trade were actually gold and silver coins, many of which looked like European gold coins from hundreds of years ago. If in the human world, these antique gold coins, one can buy a truckload of clothes, but here they are one for another.

In addition to showing that these people have a lot of gold and silver coins in their hands, it also shows that there are a few people in the Sea Tribe, who monopolize the trade with human beings, use these practical things to drive consumption, and by the way, get away the gold and silver coins that the ordinary people of the Sea Tribes have searched from the bottom of the sea, and these people know the true value of these gold and silver coins.

When the elites of the Sea Tribes want to go ashore and grab living space with humans, they promote the human way of life within the Sea Tribe, which is nothing more than to integrate with humans, and wine, food and weapons are the most easily accepted commodities by the bottom Sea Tribes, as well as lighting and clothes, which make the ignorant ordinary Sea Tribes feel strange.

Zhang Yi didn't see fish nets, pots and pans or anything like that, let alone game consoles, books and audio-visual products, because these low-level sea tribes didn't need these, and ordinary consumer goods of human beings were what they were interested in.

Zhang Yi came to look for trouble, so he didn't stop long, he quickly swept out, grabbed shorts and hoodies from the stall and put them on, and quickly walked through the market and continued to walk through the upper passage without alarming the sea tribesmen who were crowned by the monkeys.

Zhang Yi didn't kill people because he was looking for the elites of the Sea Clan, they were the rulers of the Sea Clan, and it was those people who brought about the human disaster, and Zhang Yi was sure that those people must have lived close to the ground.

As expected, after Zhang Yi went up and bypassed more than a dozen ordinary blocks, he finally saw a heavily guarded place, which was a closed castle formed by a natural cave, with a large underground space, and the exit was originally very wide, but it was built with a stone barrier, and it became a place that was easy to defend and difficult to attack.

There are a lot of guards at the entrance of this castle cave, although they are all sea tribes with tails, but they are all human individual weapons, both hot and cold weapons, they are definitely not guarding against intruders like Zhang Yi, but the sea tribe below, since there is vigilance, it means that a class has been formed within the sea tribe.

Different from the mobile lamps and lanterns of the sea tribe with batteries in the block below, in this closed cave, the lamps and lanterns that are fixed are all connected by cables, and they are arranged very neatly.

The sea tribes are intelligent creatures, because the food is fish, the bottom of the sea is abundant, they live carefree for hundreds of thousands of years without change, it is the roar of human steam-powered ships that awakens them.

The last time Zhang Yi used his divine sense to interrogate the Sea Clan, he learned that although they had been breeding for hundreds of thousands of years, they had only been ashore for a hundred years, and they were competing for space with humans because submarines and bombs made them feel dangerous, so some of them went ashore to find out.

As a result, they found that human beings are developing faster and faster, and the strange things of human beings can be easily obtained from the bottom of the sea, and they can easily enjoy the top human enjoyment with the gold and silver from shipwrecks on the seabed.

Over the past hundred years, their elite has actually germinated ambitions, vainly trying to go ashore and compete with humans for living space.

After all, they are creatures of hundreds of thousands of years, and the way of planning is indeed very clever, using human elites to let them have the most cutting-edge technology of human beings, and in order to break into human society, they even have to make up their appearance as human beings.

Human cloning technology has helped them the most, and with their funding, elite human scholars have actually researched the most cutting-edge cloning technology.

Although Zhang Yi moved their laboratory, the technology had been brought to the main base by them, and many clones were created after Zhang Yi emptied the experimental base.

Zhang Yi came to explore the camp this time to deal a devastating blow to the Sea Clan, completely withdraw the technology of human beings, and let the remaining Sea Clan continue to return to the bottom of the sea to eat raw fish.

If you want to continue to explore upwards, you must enter this castle-like large cave, Zhang Yi's divine sense has already scanned, there are three upward paths in the castle, which are very carefully excavated, much smoother than the ventilation passage below. Just by looking at the road, you know that the higher you go, the higher the status of the people inside the Sea Clan.

Zhang Yi didn't want to startle the snake, and he was not sure that he could deceive the guards, so he didn't think about sneaking in from the door, but walked to the very edge, and used a knife to cut a neat hole in the two-meter-thick stone wall.

The knife marks are all in the stone cracks, and after they are re-stuffed, no one can be seen to have moved.

Those guards were all Sea Clan warriors, not as sensitive as the maid robots, and they didn't expect anyone to break through the wall, so they all nested at the door, just guarding the gate, not even patrolling.

The cave in this castle is very bright, even if Zhang Yi doesn't scan, he can see everything clearly with his vision, so after entering, he didn't stay, and went up along the smooth passage after a little detour.

The passage is still very long, and it is rebuilt by using the underground cave, twisting and turning, except for the passage, there is no place to live, Zhang Yi has not met any people from the sea tribe along the way, and has always found a new space, only to find the activities of the sea tribe.

Different from what Zhang Yi imagined, this space was about more than a thousand meters underground, and it was not the cave of a few Sea Clan rulers, but a huge metal base, or a modern base.

The Sea Clan can manipulate the human elite to serve them, and of course they will spare no effort for the development of their base camp, they have enough funds and enough human labor to complete this base. The underwater bases on the islands that Zhang Yi had people destroy were for the purpose of building this base.

When Zhang Yi scanned a factory with many people working, he found that there were many humans operating advanced processing machines in modern factories in one-piece overalls. Zhang Yi also found that the electricity used in the steel base comes from a geothermal power station, which is also very advanced technology.

Before being discovered, Zhang Yishun took a set of orange jumpsuits and put them on, and then put down the mask, as long as they couldn't see through, they didn't know that outsiders had invaded here.

This is the clothing used in the dust-free workshop of human society, and the sea tribe has moved here. The Sea Tribes practice the doctrine of take-it-or-leave-it, and from the human elite, they can obtain the most cutting-edge technology, not to mention this technology from decades ago.

Seeing the appearance of humans in the base, Zhang Yi didn't want to hide anymore, so he swaggered around directly, and soon Zhang Yi blended into the humans in the same costume, Zhang Yi repeatedly scanned the bodies of these people, confirming that they were humans, not clones.

Zhang Yi hadn't figured out what to do with these people, so he didn't act rashly, and after wandering around to the human living area, he sneaked directly into a dormitory and began to wait for the humans to go home.

Zhang Yi wanted to talk to them, if he could get help from humans, it would be much easier to get things done.
