Everyone couldn't help but laugh at Dr. Ji's actions.

Xiaoxi's face darkened: He looks like a country bumpkin, absolutely unbearable to look at.

Xiao Nai is very tolerant; any normal Earthling would react this way upon seeing a mecha.

"Dr. Ji, why are you so happy? You need to be selected to operate a mecha."

As expected, Dr. Ji's laughter stopped abruptly. "Oh, then hurry up and test it. I read in the novel that it takes a 3S warrior to operate a mecha."

"Look at what you're saying, it's both right and wrong. We're only facing Earthlings. The S-class warriors you're talking about are for interstellar warfare."

Everyone just needs to reach level D.

Other key factors include physical and mental qualities, reaction speed, professional knowledge, and the need for training and experience to achieve a certain level of adaptability. Of course, the most crucial element is teamwork ability.

Dr. Ji was scratching his head in frustration and urged Xiao Nai to quickly test everyone.

Sure enough, Xiao Nai took out an instrument from the control room. Just like in all science fiction novels, the instrument looked like a crystal ball.

Everyone placed their hands on the crystal ball and observed the changes in the beams of light within it to determine whether they had reached the required level.

Dr. Ji couldn't resist taking the first test, and to his surprise, he got an A grade, which filled him with ecstasy.

But Xiao Nai dissuaded him, saying, "Dr. Ji, even if your combat strength and mental strength meet the standards, your body is already over fifty years old. I advise you not to push yourself too hard."

Dr. Ji immediately became dejected and sullen.

To everyone's surprise, Xiao Nai said, "With your strong mental fortitude and solid professional knowledge, you would be a good fit as the chief controller."

The chief controller is a high-ranking leader, and that's no small feat. Dr. Ji became excited again.

Then Jack, John, and the others went to take the tests, and their B and A grades were all pretty good.

Since Ye Aotian had to command the overall battle, he didn't participate in the test. Xiao Xi must have wanted to pilot the mecha, and her test result was actually 3S level.

This was hardly an accident for her. She had cultivated to the Nascent Soul stage, and her overall qualities were far beyond what ordinary people could compare to.

Ye Lingfeng also went to test it, and it turned out to be a single S.

Bei Chen's mission involves using spiritual energy arrays and other offensive techniques, so he doesn't need to control the mecha.

Finally, based on everyone's situation, Xiao Nai selected ten relatively lightweight and agile mechs, which were about two stories high.

Xiao Nai said this was the most suitable for them, as those heavy and massive mechs were used for interstellar warfare.

Xiao Nai also mentioned that these mechs also need Radiant Crystals to provide energy. Xiao Xi immediately took out ten Radiant Crystals from her consciousness space and handed them to Xiao Nai.

Xiao Nai loaded them one by one into the tail energy pod of the mecha.

Once the mechs are fully charged, they seem to come alive, radiating a dazzling light.

The mecha's outer shell became indestructible, gleaming with a metallic sheen, its lines more rugged, and it exuded a sense of power.

Energy flows inside and outside the mech, driving the efficient operation of various systems.

The engine emitted a deep roar, and its powerful engine allowed it to move quickly and perform various difficult maneuvers at any time.

The weapon systems were also activated, with energy cannons, laser swords, and other weapons that were terrifying, as if they were ready to attack the enemy at any moment.

When fully charged, the mech becomes an indestructible fighting machine.

Everyone was shocked and filled with awe.
