The first ray of vitality...

As this line of text emerged, over the barren sand table, the spitted ether merged into a wisp of cloud, floating empty, and then slowly sank to the earth.

Integrate into the rapidly evolving world and disappear.

There was no change in his field of vision, but in Lin Tuo's vague perception, there seemed to be a hint of life in the absolute desolation.

"Wow..."

The waves roll.

"Boom..."

The land rises and collapses.

At this moment, Lin Tuo vaguely felt that the acceleration of time seemed to be speeding up, at least compared with when he created Sandbox No. 1, the gap was significant.

The specific principle is unknown.

But even so, it still takes at least a few hours to complete the preparations for the birth of life.

Lin Tuo's eyes flashed and he came to the desk.

Pick up a ballpoint pen and notebook and record the results of this experiment.

The attempt just now was of course a small experiment, and the price paid was not much.

In the past, Lin Tuo would not have dared to be so extravagant, but now and then, for him now, obtaining ether is not an urgent matter.

He encountered a new bottleneck:

The progress of body quenching has stalled.

"Except for the changes in the body when absorbing a ray of ether, in a real sense, the first improvement in body tempering progress is my attempt to polish my physical fitness, using weight-bearing, and squeezing the body's exercise methods to speed up the body's absorption of ether."

Lin Tuo silently wrote "circle one" in his notebook.

Well, this is also the method that areas represented by Yangcheng are currently trying to popularize.

"However, this method soon became inefficient. The second acceleration was to enter the wasteland and fight with those mutated creatures..."

Lin Tuo drew a "circle two".

This step is similar to what Li Tai said, which is to tense the mind and body through fighting. Lin Tuo did it very thoroughly, so the improvement was obvious.

However, when he left the wasteland, Lin Tuo felt that the improvement in this way had slowed down. Therefore, during this period, he always focused on exercise and natural digestion.

"The third promotion was the unexpected etheric impact of the prayer candle... At the cost of a small amount of physical damage, the progress of body tempering was further advanced, but now it has stagnated again."

Lin Tuo wrote "circle three" silently, with a thoughtful look on his face.

In the sandbox, Hathaway and other practitioners' lifespans were obviously longer than ordinary people, which further strengthened Lin Tuo's idea of ​​​​evolving himself. However, he did not have a smooth evolutionary path in his hands.

Unlike in novels and stories, there is always a clear path, first level, second level... step by step, the names may be different, but the path is clear.

It's not available in the mall either.

Lin Tuo also asked Hathaway and others about this situation, but did not get a very satisfactory answer.

The practitioners in Sandbox 2 basically follow the principle of "time accumulation", that is, they spend decades practicing unremittingly and learning spell models... like this.

And Hathaway and other high-level extraordinary people are basically the result of the intertwining of talent and hard work.

The process of growing up is full of accidents, and I reach high-level transcendence in a daze, with no path to follow.

Its power is mainly based on its proficient use of various spells... Ontologically, it does not distance itself from Lin Tuo.

Therefore, after much thought, Lin Tuo decided to adjust his "strategic direction."

In the past, there was a lack of ether, so we tried every means to increase the concentration.

Right now, the quenching body has entered a bottleneck period. No matter how much aether there is, there is no point in storing it in the body. We need to find a way to break through the bottleneck.

"My personal wisdom is limited, so instead of immersing myself in thinking, it is better to provide the sandbox with sufficient training conditions and use the 'generation difference' of accelerated time to let the practitioners in the sandbox find a way."

Lin Tuo concentrated on his thoughts.

It's not easy, and the success rate may not be high, but you have to try.

Of course, this process also requires certain investment.

When necessary, it is not impossible to spit out all the ether you have saved.

"Money is money only when you spend it; money is paper if you keep it in your hands."

Thinking of this, he immediately stopped thinking too much and immersed himself in sorting out the plan, and also sorted out the collected spell books.

Speaking of which, ever since I took the time to put the new batch of books I brought back in my room, hundreds of books are piled there, which really makes it more and more in line with the temperament of a "study".

…

…

For the next whole day, Lin Tuo was not idle. He only took the time to read the public opinion on the Internet during his lunch break.

Overall it's not as expected, but there are differences in details.

The news of "black box expansion" swept the Internet in just a few hours, making people who had been shocked feel a little numb.

There are different explanations for this round of anomalies, but the most common ones are concerns.

"The black box is now as big as Europe. What if it continues to expand?" someone said with worry.

Unfortunately, no one can give the answer.

…

Time continues to pass and the sandbox continues to change.

At night, Lin Tuo took the time to take a look and found that the changes in the landscape had basically stopped, and plants appeared throughout the world.

When Lin Tuo got up early the next morning, he came to the sand table again and saw a land full of life.

In the middle of the sea, the vast expanse of land is dotted with peaks, river valleys, grasslands, forests... and you can vaguely see some unintelligent animals appearing.

Opened the running log and took a look.

This world has evolved for nearly a billion years.

"Huh?" Compared to this number, what really surprised Lin Tuo was the faintly visible wisps of blue and white aura in the sky.

"ether?"

Lin Tuo was stunned for a moment. He was convinced that humans had not yet been born in Sandbox No. 3, so where did these ethers come from? Are they the ones he vomited in during previous experiments?

But before that, they had clearly disappeared.

How could it happen again?

Surprised, Lin Tuo tried to pause the acceleration of time, and immediately used the evolution sand table to observe the distribution of these ethers.

His gaze focused on the relatively "richest" part of the ether.

It is a green and pristine mountain peak.

Using the "zoom" ability to enlarge the area, the map stretched, and more details were revealed before his eyes. Immediately, Lin Tuo raised his eyebrows.

At this moment, he actually saw an "etheric line"!

Only by practicing swallowing ether can the blue and white thread be born!

This discovery briefly stunned him.

"Something weird."

This is obviously not in line with common sense. If the "existence of ether" is positively related to "intelligent life", then the existence of "etheric thread" shows that there is life trying to absorb and cultivate.

But in this ancient era before humans were born, how could it be possible?

"No, that's not right, this is different from the lines produced by practice." Lin Tuo suddenly realized this.

Whether it's around Yangcheng or the extraordinary beings in Sandbox No. 2.

As long as you can enter the state of cultivation and cross this threshold, no matter what your talent is, the etheric threads generated will always be obvious.

But the line in front of me is even thinner than the line drawn by the least qualified person.

The color is also lighter.

It's weak, as if it could break at any time.

This was also the reason why he didn't notice it until he narrowed his perspective and was able to observe it.

"What is it?"

That extremely thin, extremely small line made of green and white air hung high in the sky at one end and fell into the dense forest on the top of the mountain, but the history could not be seen.

Lin Tuo did not hesitate, and immediately reached out his right hand towards the mountain peak. At the same time, the light in the transparent palm condensed, summoning the clone.

"Consciousness switch!"

…

The next second, inside the huge black box of the Pacific Ocean.
To be continued...
