There is a small bird called "Egyptian plover" in nature, which may not be understood by many people, but when it comes to its other name,—— toothpick bird, I believe most people will show a sudden expression.

Just like the toothpick bird, the "A1" test subject is also synonymous with weakness in the Zero test field, which is surrounded by the strong group, and the intelligent toothpick bird uses its intelligence to actively provide regular "oral care" for the powerful crocodile, and every once in a while, the toothpick bird will burrow into the crocodile's mouth and peck at the minced flesh between the crocodile's teeth.

This not only fills your belly, but also ensures the health of your crocodile teeth.

In addition, the alert toothpick birds also take on the duties of guards, because they can fly, so the field of vision is wider than that of crocodiles, so once any danger is detected, the toothpick will cry loudly to warn the crocodile.

In return, the crocodile will not only allow the toothpick bird to peck at the food debris in its mouth, but will also actively provide protection for the toothpick bird.

Although there is still a lot of debate about the "reciprocal symbiosis" relationship between toothpick birds and crocodiles, everyone who has ever seen this phenomenon, or heard about it, will applaud the wisdom displayed by the little toothpick birds.

Therefore, the "A1" test subject is the "toothpick bird" in Proving Ground Zero.

Unlike the "B1" test subjects, who have a unique talent for settling down in ventilation ducts to evade the prey of other more powerful test subjects, the "A1" test subjects have their own way of working for the powerful test subjects that occupy the main test grounds.

As powerful as this turtledove, whose name is not yet known, it has never bothered about food or anything like that, because it is so powerful that there is no test subject in the huge Zero test site that is no match for it.

A being as powerful as it is would not lack a few pieces of meat for the "A1" test subject, so instead of filling the belly with these little things as desserts, it is better to let them clean the environment inside the main test site for themselves, after all, a better living environment is always a bad thing.

In this way, this group of "A1" type test subjects settled in the main test site, they usually live by eating the minced meat on the wreckage, and after eating, the bones of these test subjects will be moved out of the main test site and thrown far away, otherwise the main test site will have been filled with the bones of various test subjects over the years.

Now that these "A1" test subjects are staying in the main test field, it is important to know that this is a forbidden place for other test subjects, and with the deterrent power of that test subject, they can survive to this day.

……

"So that's what happened," after listening to the worm's explanation, the turtledove finally understood why this group of "A1" test subjects appeared here, "I didn't expect them to be quite smart, and they knew that they would work for others in exchange for their protection." ”

"Isn't that what you say, don't think of the test subjects as fools in the future, their IQ is very low, but that's relative to the mentally sound humans, if compared to the beasts, the IQ of these test subjects is still very high."

After figuring out what these "A1" test subjects were doing, the little worm didn't mean to communicate with them here and exchange their work experience, only to see the little worm take a step forward, and there was a commotion among the "A1" test subjects.

Obviously, they are used to living a stable life, and they are no longer full of desire to fight like other people of the same kind, and the turtledoves and insects have also met many groups of "A1" type test subjects before, those guys are really fierce, all of them are fierce, how can they be like them.

Seeing that the insect took a step forward, the turtledove also hurriedly followed, he looked at the large group of "A1" type test subjects in front of him, and whispered to the insect next to him:

"Well, do you want me to go up and kill them all?"

"I don't think I need it," the worm observed the situation, and was somewhat sure in his heart, "They shouldn't cause us any trouble, you look at me." ”

As he spoke, the worm took a deep breath and slowly walked towards the "A1" type test subject in front of him, in order not to let them feel too much pressure, the little worm deliberately slowed down his steps very slowly, seeing that the nearest "A1" type test subject was less than five meters, the little worm couldn't help but pause.

If you directly greet them with your fists and pistols as Turtledove said, twenty or thirty "A1" type test subjects really can't cause much trouble to them, the key is that in that case, these test subjects won't stupidly stand there and stretch their necks to kill you, it will take a lot of time to completely solve them, and what Worm and Turtledove lack most now is time.

Roughly calculated, there is not much time left for the "universal serum" to break out in the body, and the fourth side effect is not good when it will appear, so it is better not to make any more extraneous branches in this situation.

So the bugs decided to take a risk and see if they could walk directly through the middle of so many "A1" test subjects,—— the bugs were betting that they weren't too aggressive, and it would be best if they could get over as soon as possible, and if they wouldn't honestly let themselves go, it wouldn't be too late to do it again.

The insect is getting closer and closer to the "A1" test subject, and it is impossible for the turtle dove to let her risk in front of her alone, so he takes two steps and follows the little worm, and the turtle dove moves like this, and the "A1" type test subjects around him become nervous.

"Move lightly," the little worm tilted his head slightly and whispered to the turtledove, "try not to make too much movement, follow me, and let's move forward little by little." ”

As the insect expected, the "A1" test subject, who has been cleaning for many years, has been used to these days, and when they see two outsiders approaching them, they instinctively want to find the test subject who is in charge here, but the big brother is fighting with a group of explosion-proof robots outside, how can he come back.

Without the protection of the subject, these "A1" subjects were a little intimidated, and they watched the insects and turtledoves approach them step by step, not only did they not attack them in groups, but they even took the initiative to make way for them.

In this way, the turtledove followed behind the little worm, and without any effort, it passed through the main test site of test site zero.

……

Out of the main test site, the little insect wiped the beads of sweat from the corner of her forehead, she was really afraid that those "A1" type test subjects couldn't hold it back just now, and came up to compare with herself, but fortunately, nothing happened after all, the little insect happily snapped her fingers at the turtledove:

"Come with me!"

The two of them ran all the way along the passage, and the little worm had already memorized how to get to the research center, and she led the turtledove for more than ten minutes, passing through several forks, and finally came to a closed sliding door.

Just as they pondered how to open the sliding door, a voice came from the communicator next to them:

"I didn't expect you two to actually cross Proving Ground Zero." - It's the mysterious man.
