210: Really impressive

Having understood this point, Gu Xiheng's confidence swelled like never before; even without Ai Yue and the others, they had nothing to fear!

"In that case, I won't force you. By the way, Gong Qiuqiu, if your Safety Tower ever needs anything, you can contact us for cooperation at any time!" Gu Xiheng said, looking at Gong Qiuqiu.

"Certainly!" Gong Qiuqiu replied with his usual gentle smile.

"Good, then I won't disturb you further. Let's go!" Gu Xiheng made a hand gesture, and his squad quickly followed behind him.

A moment later, the group disappeared from sight.

Shortly after, Ai Yue and the others heard the roar of zombies coming from the direction of the zombie tide.

The sounds of muffled thuds and pops were incessant.

One could imagine that the battle was intense.

"Is that iron lump of theirs really that powerful?" Gong Qiumu asked curiously.

"It seems so! I've always heard that there is a super laboratory beneath Yingjin Safety Tower that has been researching all sorts of ultra-advanced weapons. This iron lump is likely one of them," Gong Qiuqiu said.

"If there's a chance, we should get some, but not right now. We'll wait until they upgrade them further and make them look a bit better before we trade for them," Ai Yue said after a moment's thought.

"Haha, I didn't expect you to care about aesthetics!" Gong Qiuqiu said, amused.

"Let's follow them and see if that ugly thing is really as good as he says!" Ai Yue laughed.

Everyone was curious and agreed with Ai Yue's suggestion.

The group hurried in the direction where Gu Xiheng and his team had disappeared, quickly arriving at the scene.

Ai Yue and the others climbed to a high vantage point to look out. They saw Gu Xiheng and his team deep within the zombie tide, clad in high-tech gear, holding those black lumps and firing in all directions, appearing quite at ease.

They saw them raise their hands, and with a soft 'poof,' a streak of light flashed, and a string of zombies nearby was gunned down.

"I didn't expect what Xiheng and the others said to be true; these guns are really easy to use," Mo Li said with a look of amazement.

As Ai Yue watched, she couldn't help but nod.

Formidable, truly formidable!

"What's wrong? Regretting not agreeing to Gu Xiheng?"

Gong Qiuqiu couldn't help but tease Ai Yue when he saw the look of admiration in her eyes.

"Hehe, regret is out of the question. He wanted us to join the Safety Tower as the price, losing our freedom in exchange for the right to use those iron lumps."

Ai Yue paused and then continued, "Do I look stupid or foolish to you? No matter how good it is, I can't drag our whole family into it.

When we joined their Safety Tower before, whenever there was danger, wasn't it the three of us who were out in front? I don't want to be reduced to the base's hired thugs again!"

Ai Yue said with a calm expression.

With their family's current level of ability, they were already capable of walking freely through this world.

However, that black lump was a combination of high technology and Superpower crystal cores, and its effects were indeed beyond imagination.

The results obtained were indeed excellent!

It was just too ugly!

She wouldn't sell out her family for such an ugly thing.

This thing had just come out and was surely scarce; to be able to allocate it for her family's use, they would definitely have to pay an equal price.

There was no doubt about that.

Gong Qiuqiu said, "Regardless, this thing developed by their Safety Tower is indeed formidable. If it can be mass-produced, even ordinary people without Superpowers could go to the front lines to kill enemies. It's truly incredible, one could say it's an epoch-making invention."

Ai Yue remained noncommittal upon hearing this.

Over there, Gu Xiheng didn't know someone was observing him. At this moment, he was focused on killing zombies, having killed an unknown number of them.

In a short period, the seven-person squad had already collected over a hundred crystal cores.

They also noticed that the number of evolved zombies had increased.

Level 1 zombies, besides being a bit faster, didn't have any other special abilities.

Gu Xiheng and his team were prepared for this, and the Level 1 zombies were killed at will.

The group watching from the heights eventually had to admit that the super-powered weapons in the hands of Gu Xiheng and his team were indeed powerful.

"Sister, it's getting late. Let's go quickly." Little Girl Ye Rui wasn't interested in that iron lump at all. After watching for a while, she still felt her own Superpower was more useful, and as time passed, she became a bit impatient.

Seeing the sky grow dark, she finally couldn't help but speak up.

Ai Yue looked at the sky, nodded, and silently retreated with the others.

Meanwhile, Gu Xiheng and his team were also gradually moving toward the base gates.

Gu Xiheng did not encounter the Level 2 zombie that could control the Devil Frogs.

At this moment, this zombie that Ai Yue and the others had speculated about was hiding under the wall on the side of the base, its cold, blood-red eyes staring fixedly at the Ability Warriors constantly patrolling the city walls.

From time to time, disgusting slime dripped from the corners of its mouth.

It made no other move, just quietly watching from within the zombie crowd.

Another seven or eight days passed, and Ai Yue and the others had harvested a large number of crystal cores.

The crystal cores the others had were enough for use in the coming period; only Ai Yue still felt she had too few. Except for Ai Guosheng and his family, who knew why she was so short on them, Mo Li and the Gong brothers were very puzzled.

However, they were tactful enough not to ask to her face, assuming she just wanted to collect as many crystal cores as possible.

Lately, news about the zombie crystal cores had spread.

Gradually, people began coming to the outskirts of Yingjin Safety Tower to kill zombies.

Ai Yue understood that as long as people knew this news, no matter how dangerous it was, there would always be those who couldn't resist the temptation to come here and hunt.

This also led to many people losing their lives here.

That evening, after receiving a call on his satellite phone, Gong Qiuqiu's expression became extremely grave.

Ai Yue couldn't help but ask, "Gong Qiuqiu, has something happened?"

"Brother, it couldn't be that our base is also under siege by zombies, could it?" Gong Qiumu asked urgently, his face pale with alarm.

Hearing this, Gong Qiuqiu shook his head. "No!"

Upon hearing that their own base was fine, Gong Qiumu's heart returned to his chest, and he stopped worrying.

"Then what is it?" Ai Yue asked.

Gong Qiuqiu said, "My father just called and said that the white mist at Tianou Safety Tower shows signs of spreading!"

"What? You mean the Tianou Base that was taken over by that giant monster?" Mo Li asked for clarification.

"Yes!"

"I heard that these zombies were formed because people inhaled that white mist and got infected with the zombie virus. Is that true?" Mo Li asked again.

How humans were infected with the zombie virus had always been kept secret, and few people knew the specific truth.

Hearing Mo Li's words, Gong Qiuqiu nodded. "That's right. The white mist contains the zombie virus. Once inhaled, a person will turn into a zombie within 24 hours. There is no cure!"

"If the white mist keeps spreading, I'm afraid we'll be infected too," Ai Yue said in a low voice, her brow furrowed slightly.

"Correct!"

"Then what should we do?" Gong Qiumu asked.

Gong Qiuqiu looked up into the distant darkness, his gaze firm as he said softly, "What else can we do? Naturally, we must kill that unknown monster, and the zombie virus will naturally be resolved."
