Crossing the island chain and entering the Pacific Ocean, the north wind suddenly became stronger, and the Ruyi was speeding in the waves, and the speed of the sail power reached 33 knots.

This includes the practice of absorbing kinetic energy, Zhang Yi has been groping, but he has not mastered it yet.

A few days later, when they arrived at Seminoi Island, the six people anchored the boat on the edge of the island, and then Zhang Yi and the three of them each carried a rifle to the island, and let the three of Bill sail around Wuzhi Mountain to photograph the periphery.

There is a depression in the middle of the five large peaks, and there is a small lake, and there are no big trees on the island, only wild grass, but the wind on the island is too strong, and the dust is blown away, and many places are smooth stones, and only a little moss grows.

Zhang Yi found this island from the picture information, but there are not many pictures, they are all some photos of the periphery, and the satellite photos are also very blurry, the reason is, of course, that the nuclear test island next door is doing trouble, so I came to see it in person.

In the next two days, Zhang Yi used visual inspection to draw a map of the interior, and also drew a contour map of the entire mountain, and Bill took four people to start shooting the situation inside, and the photos and videos looked more intuitive.

As long as Zhang Yi asks, there are a lot of design masters who will design here, there are actually nine volcanic cones on this island, and the formation time is in sequence, the volcanic cone that erupted first was covered by the later magma, and because of the collapse, there are only five large mountains and lower mountain passes left, enclosing the entire island out of the anti-S-shaped valley, like the palm of the hand.

The width of the valley is four kilometers, the narrow part is also one kilometer, and after straightening, it is ten kilometers long, a total of more than 20 square kilometers of the valley, as long as it is well transformed and developed, it is enough to build a very wide cultivation holy land.

There is a gap between the two volcanic cones on the north side, the lowest point is only 50 meters above sea level, only 30 meters higher than the lake in the valley, and there is a collapsed volcanic cone on the south side, which is only 75 meters above sea level, and the rest of the city is more than 500 meters.

Two gaps, one in the south and one in the north, form a wind through the hall, so that the valley is constantly windy all year round, and even the snow is very little.

The first step to renovate is to plug the gap in the north, which is only more than 30 meters wide below, very steep and upward, and more than 80 meters wide at 200 meters, and then the width suddenly becomes larger, as long as a 200-meter-high wall is built, the air inlet can be blocked.

Now there are minus 25 degrees on the top of this mountain, and the ice and snow are not slippery at all, Zhang Yi cautiously walked to the edge of the crater, looked down, and found that the snow in the crater below was very flat, so he said to Tang Ru: "This is a volcanic lake, but the surface water is frozen, and the snow falls on the ice surface, so it is so flat, I want to try how thick the ice is to determine whether there is a hot spring down here." ”

Tang Ru immediately asked Zhang Yi with concern: "Do you want to go down and dig it?" The top of this mountain is far from the crater lake, and it is vertically down, a depth of several hundred meters, and it is obviously not a good idea to go down and chisel.

Zhang Yi shook his head and said, "No, it's very simple." ”

Zhang Yi rolled a snowball on the top of the mountain, and soon rolled a snowball with a diameter of more than half a meter, Dani immediately helped roll up, the snow on the surface is this year, and the old ice below is distinct, the snowball is easy to roll, the two have been rolling in circles, and finally rolled to the top of the mountain pass, and pushed it up, after the snowball turned over the hurdle, it rolled into it by itself, and finally got bigger and bigger, and finally rose into the air, and fell straight to the lake below.

The snowball shattered on the surface of the lake, making a dull sound, echoing in the crater, shaking the snow in the inner circle of the crater and falling one after another, this is an avalanche, because the snow is mainly a glacier under the snow, and the avalanche is not large, just a circle of snow falling on the lake.

However, the impact of the big snowball just now had obviously disrupted the balance of the ice surface, and the ice below first rippled for a moment, and then there was a sound of ice tearing, and from above, the harsh clicking sound was endless.

The constant snow falling on it, and the change in weight, exacerbated the tearing of the ice surface of the volcanic lake, and finally the water on the surface of the lake kept turning up, and many ice blocks that had fallen with snow were crushed up.

Zhang Yi looked at the fracture of the ice cube that was only ten centimeters thick, and said to Tang Ru with a smile: "The ice surface is very thin, there are hot springs under the volcanic lake, and the surface water will freeze in winter and melt in summer." ”

Quite simply, if it doesn't melt in the summer, the ice below will not know how thick it is, and it may even become a complete glacier.

Tang Ru said: "This volcanic lake is so deep, there is no way to use the hot springs, it's a pity." ”

Zhang Yi said to her: "If you think about it carefully, you will know that you can use it." ”

Tang Ru said: "Do you use a water pump to pump down? This is too deep, how big a water pump is needed, there is no electricity here, and if you get a diesel engine, you will pollute the white glacier here." ”

Zhang Yi said with a smile: "You think too much, but you don't think of the key points." The ice is freezing, but it is not thick, and the snow is flat, indicating that the height of the lake has remained the same, which means that there is water overflowing from the volcanic cone at the surface of the lake, and we can use this hot spring as long as we find the place where it overflows. ”

As soon as Zhang Yi said this, both of them were moved, and immediately went down to the valley to find the possible overflow point.

As a result, they searched around, but did not find the discharge point, Zhang Yi took them around from the side to the periphery, and finally found the discharge point, the water flow was not large, it was flowing out under the ice surface of the mountain, and it flowed down the mountain into the sea.

Zhang Yi went back to the inner circle, looked at a small canyon and said: "The water discharge point outside is very small, which means that there is no spring inside, just the geothermal heat of the crater, melting the ice on the surface, and when it reaches the discharge point, the water surface will no longer rise, and this volcanic lake should be very deep." If we open the door from the cave inside, we will be able to give priority to the use of water.

The water is very simple, the biggest disadvantage of this valley is that the wind is too strong, but it is also easy to solve, as long as the V-shaped gap is built a wall, the surrounding wind through the valley is gone, the lake water evaporates not so fast, the lake surface is at least four times larger, the lake in this valley is surrounded by volcanic cones, it is also very deep, the surface layer is not frozen now, there is geothermal heat under the bottom of the lake, it should also be a hot spring, the lake water vapor is transpired up and not blown away, and the fog can be formed when it is cold above the valley, blocking the air inlet, and the greenhouse effect can be formed in the valley, as long as the soil is transported, anything can be planted on the slopes。 ”

The two women immediately said, "Then build a wall and carry earth, we will live here in the future." ”

Both of them are foundation builders, and their divine senses also cause them trouble, especially when they go out to negotiate contracts, they meet wolf-like admirers.

Zhang Yi has already experienced this experience, and after two paintings, his divine consciousness has been sent and received freely, and now he feels normal. They can't do it yet, but they can feel more comfortable living in a valley like a paradise.

Zhang Yi made up the shape of the mountain, and chose the location of the cave to be the east side of the highest mountain in the west, just overlooking the entire valley, and the lake is down from the hillside.

The cave is chosen at a height of 500 meters, as long as you dig in, with the back of the crater lake, the cave will be warm like spring, just dig a small hole in the lower cave, you can lead the water from the volcanic lake into the cave, with water, nothing else is to worry about.

Wuzhi Mountain is indeed a treasure land, Ruyi is parked at the gap on the south side of the island, surrounded by two magma flowing mountain mouths that stretch into the sea, about three kilometers wide, from the inside out, the water depth extends from 6 meters to 23 meters, as long as there is a breakwater in front of it, it is an excellent harbor, and the sea surface that is surrounded by it is five square kilometers, which can be said to be unique.

The harbor is surrounded by two mountain mouths, leaning on the U-shaped gap, the lowest point of the gap is only more than 70 meters above sea level, and the width is about 200 meters.

The two high walls and the amount of soil filled inside are very large, and other people will not spend a lot of money to do such a stupid thing, in order to build a century-old foundation, Zhang Yi is willing to do it, and he also has this money.
