Mysterious I Came a Billion Years Later.

Summons the guardian sword, suspended in the air.

Then, Lin Tian was a little empty, and one after another law began to beat on the white stone, just like a refining tool.

Boom boom boom! ! ! !

The white stone kept vibrating and slowly melted under the influence of the law of fire, heaven and earth.

After a while, the three Bai Qi stones turned into Bai Qi liquid substances.

"melt!"

Bai Qi's liquid substance covered the guardian sword under Lin Tian's control.

Afterwards, Lin Tian used an incomparably mysterious refining technique to incorporate Bai Qi's liquid substance into the inside of the Guardian Heaven Sword.

At this moment, the Guardian Heaven Sword absorbed the essence of Bai Qi's liquid substance and rapidly transformed.

Originally, the Guardian Heaven Sword only had the aura of the pinnacle of ordinary low-grade artifacts.

But soon, its aura climbed to the level of a mid-grade artifact. ..

Chapter 625 Beyond the universe, where the heaven is!

"The pinnacle of mid-grade artifacts!"

Lin Tian looked at the guardian Tianjian whose breath gradually stabilized, and showed a satisfied smile.

Although it was only elevated to the pinnacle level of a mid-grade artifact, the restriction that shackled the growth of the Guardian Heaven Sword disappeared.

As long as Lin Tian continued to engrave the pattern of laws on the guardian sword, the level of the guardian sword would continue to improve.

"Let's upgrade the Guardian Heaven Sword to the top-grade artifact level first!"

Lin Tian decided.

With his current control of the law, it is not difficult to upgrade the Guardian Heaven Sword to a high-grade artifact.

Whoa! ! ! !

Under the control of Lin Tian, ​​a trace of the law of heaven and earth was transformed into a law pattern and manifested in the void, and immediately it was as if pressed on the guardian heaven sword, and it was engraved on the guardian heaven sword.

Ordinary people engrave the pattern of the law little by little, but Lin Tian inscribes it all at once. This kind of manipulation is very difficult and easy to fail, but Lin Tian's law is highly accomplished and his level is very strong, so he dares to inscribe it like this.

In less than a while, the inscription was successful.

I saw that the guardian sword was shining brightly, and it was suddenly upgraded from a medium-grade artifact to a high-grade artifact.

"Not bad!"

Lin Tian nodded in satisfaction.

After the refining was successful, Lin Tian took the guardian sword into his body, and then returned to the guardian spirit space.

"Lin Tian, ​​where is your sixth life memory?"

Xiao Xiner asked curiously when she saw that Lin Tian was done with her work.

At this time, Lin Tian said with a heavy face: "Xin Er, the memories of the sixth, seventh and eighth generations are the same this time, they are all in the same place, but this place is..."

"What's wrong with this place?"

Xiao Xiner felt that Lin Tian's expression was not right, and couldn't help but be more curious.

"This place doesn't seem to be in the universe!"

Lin Tiandao.

"Not in the universe?" Xiao Xiner was stunned. "What does this mean? Could it be in the abyss?"

"No!" Lin Tian shook his head, "The abyss is just not on the same level as the main universe, it actually belongs to this universe, but the place I want to talk about is completely separated from the universe, you can think of the entire universe as a hollow sphere , and there are many layers inside this hollow sphere, of which the largest layer in the center is under the cosmic starry sky we live in today. This main space has countless star fields, galaxies, planets, and the most creatures!"

"And the abyss or some special spaces are on other levels. For example, the Tianzun Mountain you see is located in the depths of space, and it also belongs to a certain level of the universe."

"And the place I'm talking about is not on any level of the universe. If I really want to talk about the specific location, it belongs to the spherical surface of this hollow sphere, and it is no longer inside the hollow sphere, so it does not belong to this universe!"

After Lin Tian finished speaking, Xiao Xiner was shocked.

"Lin Tian, ​​what is beyond the universe?"

Xiao Xiner has always been ignorant of this issue, and has never cared about it. Now that she heard Lin Tian say this, she became a little curious.

"Beyond the universe is chaos!"

Lin Tian murmured.

In the fifth reincarnation, he has entered the chaos more than once. Although he has not gone deep, he has really entered the chaos, so he has some understanding of the chaos.

"chaos!!!"

Xiao Xiner finally understood the origin of the word Chaos. It turned out to be from a region outside the universe.

Once, she had also heard of Chaos, but thought that Chaos was a special level, but she did not expect it to be outside the universe.

"Lin Tian, ​​can you tell me about Chaos?" Xiao Xiner said.

"Yes!" Lin Tiandao said: "Chaos is very big, and I don't know how big it is. I only know that Chaos is far bigger than this universe."

Under Lin Tian's narration, Xiao Xiner gradually understood the concept of chaos.
