In ancient times, Taihu Lake had an area of ​​about 2,400 square kilometers, making it the second largest freshwater lake in China.

After the Doomsday War, due to the changes in the terrain, the area of ​​Taihu Lake has expanded a lot. According to the statistics sent back by satellites, it has reached more than 6452 square kilometers, and the deepest part has reached more than 300 meters.

Yunying should have gone back safely. As for whether it is complete or not, let’s talk about it, at least the surface is complete...

Because, in less than a long time, a large army drove on the lake and began a meticulous search.

But the area of ​​more than 6,000 square kilometers, coupled with the ferocious mutant beasts, such searches are just routine. Horse Ping'an under the water is still very comfortable and comfortable.

At this time, Ma Ping'an was swaying at the bottom of the 6452 square kilometers of lake, with his small eyes staring brightly.

Mechas don't appear for a long time, and ordinary mechas in the water cannot exert their original power, so exploring in such large lakes and oceans is often much more dangerous than land.

But because of this, this kind of place has become an uncultivated virgin land. Although no base was found, Ma Ping'an still gained a lot.

In three days, a total of two A-level mutant beasts, nine B-level mutant beasts, and two three C-level mutant beasts were discovered.

These are all recorded in "Mutual Creation".

After all, you can get about ten thousand rewards for discovering new species.

If all these credits are put on the head of the Beast Adventure Group, it will be enough for it to upgrade several levels in a row.

Ma Ping'an now knows why, even though he knows that there are so many expedition teams who die every year, he is enjoying it.

This money is so fucking easy to make!

Everyone in the world is bustling for profit...

Of course, if there were no such a powerful and perverted mecha as the Dragon Warrior, it would be possible that the reward would be gone before it was received.

The only thing that doesn't feel good is... Some things seem to be inconvenient...

Forget the stomach problems.

Although I didn't expect to delay for so long outside, I only brought a day's compressed dry food and water bags when I came out, but the abundant aquatic products in Taihu Lake were enough to prevent Ma Ping'an from having hunger.

If you are lucky enough to find a lot of fresh water oysters, it is a good thing to strengthen your aphrodisiac. I just consumed some yang energy a few days ago and I need to replenish it!

But the excretion problem after eating has become a problem.

Although it is impossible to turn the entire Taihu Lake over and search carefully, there is still no big problem in monitoring the lake surface.

Patrol aircraft passed by from time to time on the water, and satellites were being monitored firmly above their heads. Ma Ping'an did not dare to rashly expose the water to find a place to solve the problem.

At the bottom of the water, the driving compartment cannot be opened, and small prey can be sent to the driving compartment through the sealed transmission channel.

But if you go out, no matter how high Ma Ping'an's butt is, it will not be able to aim at the small hole. In the past three days, Ma Ping'an has been so distressed...

Fortunately, after three days, the search range seemed to have moved to other areas, and the lake gradually calmed down. Finally, on a dark and windy night, Ma Ping'an, who already had a balloon-like bladder, found a relatively safe place to get ashore.

This is one of nearly a thousand islands in Taihu Lake, surrounded by sharp-toothed black reefs on all sides.

These reefs are rich in metal components. Under their protection, even if the satellite is equipped with metal sensors, the mecha's movements are safe.

I carefully observed the situation around me. The aircraft that was shuttled over the lake twenty-four hours a few days ago was gone, and the calm lake surface was extremely quiet.

Occasionally, fish will jump out of the water, rippling and rippling, but they will soon return to peace.

After confirming that it was safe, the mecha climbed up between the two reefs.

This small island is very strange and not as full of vitality as other islands. Behind the reef is a steep mountain wall dozens of meters high and surrounding the entire island.

The grass does not grow on the mountain walls, and it is so dark that it gives people the illusion that it is about to collapse.

Fortunately, there were still several narrow and flat rocks between the reef and the mountain wall. Ma Ping'an hurriedly rushed out of the mecha, walked around behind the reef, quickly took off his pants, and squatted down.

After his whole body was relaxed, Ma Ping'an walked towards the Dragon Warrior. After walking two steps, he suddenly realized that the reef in front of him seemed a bit strange.

The part of the reef with a diameter of about three meters above the water is about seven meters high. Although the moonlight is dim, you can still see a little metallic luster flashing on the black reef, just like the stars in the sky in the dark night.

"Well, these stones should be the product of the center point during the nuclear explosion..."

The high temperature at the moment of the nuclear explosion center can dissolve metal, rock, and soil. After mixing it together, such stones will be produced.

There was a little silver and dazzling place closest to the water. Ma Ping'an squatted down again and gently stroked it with his index finger. It was a round and bulge with a cool touch, the size of a thumb, just like a silver pearl, shining vividly in the moonlight.

"What's this?"

Ma Ping'an became curious and suddenly remembered the secret room mechanism of the ancient zoo. So he pressed it hard for a few times and twisted it to both sides, but the thing didn't move at all.

Looking at the lake, I found that the island was surrounded by several other islands, and even if there was light in the distance, I couldn't see it. So I stood up and got into the mecha.

The Dragon Warrior walked a few steps forward, and then waved his right hand when he reached the reef, holding the light energy sword and cutting it towards the reef.

With a crisp sound of 'pop', a piece of the boss collapsed from the reef.

After brushing away the stone chips, Ma Ping'an was excited. There was a piece of silver metal in the reef, and the bulge in front was just one of its corners.

When he was happy, his hand shook, and the light energy sword in the mecha's hand turned slightly. He dinged it straight on the piece of metal.

"Damn!" Ma Ping'an was shocked. The energy level of this light energy sword is as high as 260 degrees of energy. If ordinary metals are not protected by energy, they will basically end up with one knife and two cuts.

When I picked up the knife, I was surprised again. The piece of metal was completely unscathed, and there was no trace left on the smooth surface.

I felt relieved and quickly cut it up. After a few strokes, I dug out the piece of metal. Ma Ping'an jumped out of the mecha excitedly and picked it up.

It was a metal block with a length and width of about 20 centimeters, about five centimeters thick, and it was very heavy, with smooth upper and lower sides, and straight shallow patterns on all sides, but there was no gap at all in front, back, left and right. It shook it close to the ear, and it felt like it was solid.

Ma Ping'an thought for a long time but couldn't figure out what it was.

Alloys are very strange.

In theory, it is a very simple and straightforward thing to do which metal and which one will produce what effect it will produce.

But in fact, the simplest pairing of hundreds of known metals in existing pairs is astronomical.

Not to mention the synthesis of multiple metals, each type needs to be determined to have a certain proportion, which has an almost infinite possibility.

Therefore, in theory, each alloy is found to be based on luck, and it cannot be copied without samples and detailed data.

The metal at hand cannot even be cut by the light energy sword. The hardness can be imagined. It can be kept intact during a nuclear explosion. The melting point must be super high, and it must be a special alloy.

Take it back and let the two random thoughts analyze the ingredients, and you should be able to synthesize them by yourself. When the plate is placed on the mecha, it may increase the defense of the mecha to a higher level. It is a treasure.

Ma Ping'an smiled and took it back into the driving compartment.

Speaking of which, the mecha design before the Doomsday is really humane. The Dragon Warrior's driving compartment is spacious, with powerful internal audio, and a 360-degree ring virtual screen...

Not to mention the complete entertainment facilities, there is even a small refrigerator and several storage boxes on both sides.

Many of the mutant beasts offered by the alliance are huge in size, so it is unlikely to carry the entire body to receive the reward.

Therefore, the alliance sets some special parts as the basis for hunting mutant beasts according to the differences between each mutant beast. As long as you take these parts, you can consider it as you completing the reward.

For example, the crystal core of the Flying Beast, the short whiskers of the Ice Squid, etc., the refrigerator and storage box are now filled with such trophy.

Ma Ping'an searched for a long time and didn't know where to put the metal block. He would definitely not be able to stuff the refrigerator and storage box. It would naturally not affect the operation when throwing it in the cab. It was really a headache.

After flipping around, I suddenly saw a square lid on the hatch door. I opened it and felt happy. There was a small depression inside the lid, square. Seeing that the size was similar, I quickly stuffed the metal block in.

After stuffing, I was surprised. The depression was extremely suitable for the metal block, and even the vertical shallow patterns on both sides were completely in line with...

It feels like it is specially used to place this metal block.

"Damn it, it's not so coincidental. I picked up a piece of Dragon Warrior..." Ma Ping'an scratched his head and closed the lid.

As soon as the lid was closed, the virtual screen in front of him suddenly flashed, and then a round shield mark appeared in the middle of the screen. A flying dragon with teeth and claws was painted in the center of the shield, and a row of words "Huaxia Nandu Military Region" appeared below.

With the appearance of the mark, a female voice rang out from the mecha: "The certification system is started, the unit to which the mecha belongs: Equipment Research Institute of the China Magic City Security District, mecha number SHV-001, permission level A-S, can be passed. Do you want to open the base channel?"

"Why isn't the old man's crow's throat?"

Ma Ping'an stared at the changes in front of him in amazement and subconsciously replied: "Open the channel!"
Chapter completed!
