This number made Tang Ling have some regrets.

It turned out that in front of the powerful instrument, his precision instinct was a little worse.

But Su Yao looked strange, with a complicated look of excitement, heaviness and remembrance, his rough big hand stroked the screen with numbers as if he was caressing the most precious treasure.

Tang Ling clearly saw that Su Yao's fingers trembled slightly.

"One more time." Su Yao said, but his voice was obviously a little out of tune.

Tang Ling didn't ramble, and repeated it directly.

And the result is still the same, he can accurately estimate his strength, of course, it is still not comparable to the instrument in front of him.

"Again... Come..."After hesitating for a second, Su Yao made another repeated request, but his voice was completely out of his control, as if it had been squeezed out of his throat.

Of course Tang Ling did so.

But after coming to the same result again, Su Yao was completely stunned.

His eyes were slightly red, and the corners of his mouth quivered, sometimes rising slightly, looking excited and happy, and sometimes pursed, as if he was a little sad.

Tang Ling was extremely surprised, so he had to ask carefully: "Uncle Su Yao, do you still need to try again?" ”

Su Yao came back to his senses suddenly, but did not answer any questions from Tang Ling, but strode up to Tang Ling and hugged Tang Ling tightly.

Su Yao's strength was extremely strong, and even more so when he was excited.

Tang Ling was hugged by Su Yao, feeling that the air in his chest was about to be squeezed out, and he couldn't help coughing continuously.

In the face of this kind of beast-like man, he deeply felt that he had no room for resistance.

Perhaps it was Tang Ling's coughing sound that reminded Su Yao of his gaffe.

He finally let go of Tang Ling, but his excitement still made him can't help but pat Tang Ling's shoulder twice, almost slapping Tang Ling into the ground.

"Good, it's good." He said.

But the weird feeling still lingered in Tang Ling's heart, this was not too magical in his eyes, as for making Uncle Su Yao so excited?

He wanted to ask, but Su Yao had already taken two deep breaths and calmed his emotions.

"Your growth is not satisfactory, but don't be upset, you will become stronger."

Is your growth just unsatisfactory? This made Tang Ling very concerned, and he had forgotten the weirdness just now.

In fact, Tang Ling didn't know what growth was. But Su Yao cared so much, and specially brought him here to test, it must be something more important than the basic value, such as the current strength and speed.

Not strong yourself?

"Don't be without faith, I said, you'll be stronger. As long as you can grow safely, you will be very strong. But compared to Tang Ling, Su Yao was not disappointed at all, but his confident appearance made him look extremely high.

"But..."Tang Ling's heart was about to explode, one after another inexplicable, but unanswered riddles unfolded in his life, should it continue like this?

"No, but!" Su Yao's expression suddenly became extremely solemn, and he just opened his mouth and said a word to Tang Ling: "Secret!" I mean about your abilities! ”

Tang Ling was silent.

It seems that this kind of life shrouded in fog is still going to go on like this.

**

After several days of heavy rain.

After the afternoon of Safety Zone 17 cleared up three days ago, the sun was shining as if it were retaliating.

According to the division of the seasons, early summer has passed, and midsummer is coming.

And the summer is supposed to be so hot.

Therefore, this set of uniforms belonging to reserve soldiers, just by putting them on, made Tang Ling feel that it was difficult to breathe.

Although, it was still early in the morning, and even the light of day was not completely lit.

"Is that going to the test?" Tang Ling finally sorted out his luggage and put on his backpack.

He didn't have anything superfluous, except for the relics of his mother-in-law and sister, and the clothes that Su Yao gave him, all that was left was the clothes he had worn in the settlement.

He was not willing to throw it away, and that was also a memory.

And the reason why it was sorted out like this was because Tang Ling was not at ease, he wanted to wait for Su Yao to see if he would appear in the end.

The truth is disappointing.

There were no footsteps outside the door, the door was not opened, and Su Yao did not appear.

He's missing.

To be exact, he has never been seen since he took Tang Ling to the so-called training base.

After that, the cook of this small hotel was responsible for helping Tang Ling take care of everything.

It's like Tang Ling's three meals a day, like some basic introductions to the No. 17 security zone, and like the specific place and time of today's exam.

The most important thing is that this cook gave Tang Ling a library card with extremely high authority, with which Tang Ling could enter the inner city library behind the wall and read to his heart's content without time and quantity.

Of course, it is a book that can be borrowed within the permission of the library card.

Even so, Tang Ling had a feeling that time was too rushed.

For three days, except for eating, and last night's less than six hours of sleep, he soaked in the library.

But the vast sea of books was so interesting, and his strong brain with the instinct for precision could only read a fraction of the books in the library at the fastest speed.

Although it was just like that, Tang Ling felt a little closer to this world for the first time.

He first learned about the real pre-civilization.

It turns out that not only does it exist, but civilization has developed to an extremely high level.

They explored space and even landed on the 'Purple Moon'.

They have all kinds of buildings with different functions, and the level is extremely high, and the architecture has developed.

They have magical means of transport, called - cars, planes, ships....

They also have a rich spiritual world - movies, reading, television...

And then there's it - weapons!

It's a hot sight! It's unimaginably powerful. If these weapons were available, would there still be a problem with survival in this era?

Tang Ling thought about it, and at the same time, he thought of Quark's explosives and the Desert Eagle (pistol), and now he understood what these two things were.

It turns out that in the pre-civilization, these two things were nothing.

But Tang Ling's thinking has no clue, and the answer is also confusing.

Just because in pre-civilizations, humans were conquerors, and any animal could easily exterminate them if they wanted to.

Even the most ferocious beasts of the pre-civilization seem like a joke in today's times, despite the comparison.

But can this justify the extinction of pre-civilizations?

Tang Ling didn't think that the terrible nuclear weapons, as well as all kinds of fighter planes, etc., could not fight with animals, even the so-called fierce beasts.

Tang Ling remembered the black-horned purple-veined snake in the underground passage.

If so, how did the pre-civilizations become extinct? Tang Ling was puzzled.

What is even more incomprehensible to him is that the former civilization, which almost collapsed abruptly, broke off the civilization of people by surprise, and how did the current civilization be established?

It is so contradictory, just like what Uncle Su Yao said - "This era is very light, sometimes it makes me feel close to the universe, and sometimes it seems to return to barbarism." ”
