The knowledge they left behind, such as how to advance to extraordinary fire, primary glyphs, and how to cultivate mutant plants, etc., is of no use to humans.

Therefore, the value of the relics of a first-level civilization is really limited.

And the ruins of those powerful civilizations, those with more than 10,000 souls, are likely to be hidden in some strange and dangerous corners...

This is a very simple idea.

Now that the Origin Fire Civilization has found a world-class volcano to build a refuge, will other powerful civilizations think of similar methods?

For example, poisonous swamps, underground abyss, deep sea trenches, etc.

It's impossible for those powerful civilizations to survive the epochal disasters on the plains? If you think about it with your toes, you will know that they are not that stupid!

Therefore, Deep Sea is an excellent choice!

But the water pressure in the ocean is no joke, every 10 meters deep is 1 atmosphere!

The water depth of 6,000 meters is equivalent to 600 atmospheres of pressure, which is equivalent to more than 600 kilograms of force per square centimeter. This is really beyond the limits of human beings, and even a seventh-level master cannot bear it!

Therefore, the treasure-digging team has many fewer ways to explore the deep sea - puppet robots, immortal giant turtles, and... small mirage dragons!
