A solemn look flashed in Shen Lei's eyes, he slashed his fingers, flicked his fingers, and a drop of blood flew to the spine of the super synthetic beast.

As soon as the drops of blood flew onto the super synth's vertebrae, they squirmed rapidly, forming twisted and tiny spirit patterns.

Shen Lei pressed the space crystal on the vertebrae, the spiritual power operated, and a drop of blood dripped on the space crystal, and the drop of blood quickly twisted, forming a spiritual pattern like a snake and winding around the space crystal.

Shen Lei pointed at the fist-sized space crystal, and the huge spiritual power entered the space crystal at once.

The spatial crystal suddenly bloomed with a trace of colorful aura, quickly shrinking, and was embedded in the vertebrae of the super synthetic beast that was like a bracelet.

Shen Lei's spiritual power swept towards the bone bracelet, and he sensed that the space inside the bone bracelet was extremely wide, about a huge space with a diameter of about five kilometers and a height of more than sixty meters.

Shen Lei sensed the huge space, and his eyes flashed with ecstasy: "Such a large space, if you want to load some supplies, it's easy!" ”

A space treasure that can hold a large amount of materials is extremely precious in this post-apocalyptic world. With this spatial secret treasure, Shen Lei could move with a huge amount of materials and firmly control the materials.

Putting the space bone bracelet on his hand, Shen Lei took out the silver egg, groaned for a while, and cut his right hand.

A large amount of blood dripped from Shen Lei's right hand and dripped onto the silver egg.

As soon as the blood fell on the silver egg, it was directly sucked dry by the silver egg.

After the silver egg absorbed Shen Lei's blood, it continued to tremble, and bursts of joy fluctuated.

The corners of Shen Lei's mouth raised slightly, a smile appeared in his eyes, and the spiritual power operated, and the drops of blood suddenly formed small blood-colored spirit lines, which were submerged into the silver egg.

After that silver egg devoured a large amount of blood containing tiny spirit patterns, it suddenly established a mysterious connection with Shen Lei's spirit, which was several points stronger than those monsters who were controlled by the beast spirit patterns.

Shen Lei used his spiritual power to continuously convey spiritual power into the silver egg.

That silver egg was like a big hole in the abyss that could not be filled, frantically devouring Shen Lei's spiritual power, and at the same time constantly squirming, as if it was about to break through the silver egg.

Shen Lei felt the spiritual power in his body pouring out, and his face changed slightly: "Oops, if it goes on like this, my spiritual power will not be enough to supply it to be born." In this way, if it can't break out of the shell, it will definitely be hurt. ”

"What else can be done? That's right, that super synth's life source crystal! Shen Lei's mind was racing, and he took out a super synthetic beast's life source crystal and put it on the silver egg.

As soon as the Super Synthetic's Life Source Crystal came into contact with the silver egg, it was directly sucked into the silver egg.

The absorption power that came from the silver egg was suddenly much smaller.

After a dozen breaths, a powerful wave of power came from the silver egg. The skull burst out of the silver egg. Then the limbs of a beast stretched out, and they struggled to crawl out of the turtle's shell.

Not long after, a small silver turtle with a blue life source crystal inlaid in the center of an eyebrow, and the limbs were short and thick, like four pillars, appeared in front of Shen Lei's eyes. As soon as the little silver turtle came out of its shell, it immediately began to eat the silver egg shell.

Shen Lei looked at the Life Source Fusion Crystal above the little silver turtle's eyebrows, and a flash of ecstasy flashed in his eyes: "Life Source Crystal, is this a fourth-level synthetic beast?" ”

The fourth-level synthetic beast was a terrifying combat weapon far superior to the third-level synthetic beast, and the Tutang Mu'er Royal Expedition that descended on the earth back then could not manufacture such a powerful synthetic beast in large quantities.

As long as there was a fourth-level synthetic beast, all the monsters that Shen Lei had encountered before would not be his opponents.

Shen Lei looked at the little silver turtle that was the size of a palm and shook his head, and a trace of doubt flashed in his eyes: "But is this really a fourth-level synthetic beast?" No matter how you look at it, you don't have the domineering of a fourth-level synthetic beast! ”

The little silver turtle seemed to sense Shen Lei's doubts, and quickly ate up the silver egg shells, and the blue life source crystal above the center of his eyebrows suddenly bloomed with a brilliant blue light, and his body suddenly expanded.

After just a few breaths, the little silver turtle immediately swelled into a terrifying beast that was twenty-five meters tall and a hundred meters long.

A silver light shot out from the center of the little silver turtle's eyebrows, and it disappeared into Shen Lei's sea of consciousness.

Shen Lei suddenly understood the purpose of the little silver turtle in his heart: "This is the vehicle synthesis beast of the Tutang Mu'er civilization. If you reach the limit, you can evolve into a flying machine that flies in the universe. ”

On the side of the little silver turtle, a cave suddenly opened.

As soon as Shen Lei entered the cave, he saw a space with a diameter of up to 100 meters appear in front of his eyes.

Shen Lei said slowly: "Layer with three meters per layer!" ”

That ** trembled, and quickly extended, directly dividing that space into eight layers.

In this space, Shen Lei only needs one order to let the little silver turtle freely carry out the construction of various buildings.

The construction of various buildings also consumes the power of the little silver turtle, but it is also able to synthesize and replenish its huge power every day using various energy sources such as bioenergy and solar energy, so it is nothing.

Shen Lei's eyes flashed with joy when he saw this scene: "In this case, if you squeeze it, you can barely accommodate 8,000 people." It's very easy to live for a few hundred people. ”

With this big silver turtle cart, Shen Lei could quickly transfer his subordinates and relatives. The place where this ruin is located is not a safe place.

Shen Lei closed his eyes, and his huge spiritual power extended out, connecting with the little silver turtle, and all kinds of slender information immediately came from the silver giant turtle.

The silver giant tortoise could walk 200 kilometers a day with a full load of weight according to the normal way of walking. If you walk at an accelerated pace, you can walk 1,000 kilometers a day, but that would require a lot of strength, and if you don't have enough energy, you will be unable to move after walking 1,000 miles.

In addition, the silver giant tortoise can also open a protective shield called the light of life to defend against various attacks when it is in danger. Even a fourth-level synthetic beast would not be able to break through its protective shield within two or three days. This is the powerful defense it gains after sacrificing attack power.

Of course, those are only the current abilities of this silver giant tortoise, and as long as it continues to evolve, the power it has will become stronger and stronger.
