"Is there any defense on Zanbrain's side? Can we perform aerial bombing?"

Someone beside thought for a moment and then suggested, this time they had brought some high-yield explosives inside.

If Zanbrain lacks air defenses, then drones could be used for aerial bombing.

If this works, the mission should be completed.

However, as soon as these words were spoken, everyone around him gave him strange looks.

"Do you think something like Zanbrain would be placed in an open environment?"

Just thinking casually, this is an impossible scenario.

"If you want an airstrike on Zanbrain, it's indeed impossible; the building covering Zanbrain uses underground bunker engineering. To blow up such a building, perhaps you'd need nukes, maybe then it's possible."

"Using those breakthrough explosives, trying to blow this open is completely impossible."

He had been there and knew how extremely well-defended the place was.

Even nukes might not break it open, much less other explosives.

So, thinking about using explosives to blow it open is entirely unrealistic.

"Underground bunkers? Doesn't that make it even more hopeless? Such things are hard to enter."

"Wouldn't there be some sort of entrance control down there? With their technology, making some access control, I fear we won't be able to break those doors."

Upon hearing this, everyone felt even worse.

Over ten thousand robots were already a headache, and adding an underground bunker, going down would be like sending themselves to die.

"I shouldn't have taken this task."

Someone rubbed their face in distress at this moment, looking pained.

They've gotten themselves into a trap, who could have thought the task would be this difficult?

"You've been here so long, haven't you figured out anything? For instance, how to approach Zanbrain without alerting those robots?"

Lin Hua thought about it, unwilling to give up, and asked again.

"At the beginning, we used small detection machines to infiltrate below the bunkers, which is how we learned about some of the structures."

"As for how to infiltrate, we don't know at the moment."

"However, we do know the overall structure of the underground bunkers."

Wu Yong's words made everyone's expressions more melancholic.

For them, dealing with over ten thousand robots was already extremely difficult, and now the map changing to underground increased the difficulty by unknown multiples.

Thinking about it, they just felt this task was certain death.

"Let me see the photos of the underground bunker."

Zhou Yingting stood aside, thought for a moment, and said.

The danger level of this instance seems to far exceed all previous ones. If things go south, they might really not be able to clear it.

But now they were already inside, they could only try their best to find a way to complete the mission.

"Yes, it's over here."

Upon hearing this, Wu Yong perked up immediately and led Zhou Yingting over to what looked like a table.

After pressing a switch on the table, a 3D projection appeared on it immediately.

The image projected on the table was the blueprint of the underground bunker.

"Look here, this is the entrance. Go straight down this way, these are some detours leading to other directions; don't go there."

"Here, go straight forward along this path to reach the place."

Wu Yong introduced to the group, "Here is Zanbrain's location."

"Along this way, here, here, and here, there are lots of robots."

During previous detection, they had already checked almost all these places and confirmed the presence of robots at those spots.

It's impossible to sneak in swifty.

These robots are machines, patrolling tirelessly 24/7, and there are many sensor devices installed there.

For them, avoiding these sensors with just their bodies was utterly impossible.

The only way in is to fight their way in, or transform into a robot to enter.

But without Zanbrain's central assistance, consciousness uploading wasn't possible outside.

Thus, this situation entered a dead end.

Zhou Yingting looked at the map in front of him, a vexed look showed on his face.

From what he saw, the only way to get close to Zanbrain was to fight his way through.

But their strength wouldn't suffice to fight in.

Moreover, in a place like an underground bunker, once they enter, it's very likely their retreat would be cut off, leaving no means for withdrawal.

"What do you think?"

Zhou Yingting looked towards Lin Hua and the others, hoping they might have a solution.

"What do we think? How should one think here? Even if my magic doesn't require Spiritual Power, casting fire repeatedly below wouldn't be able to burn everything."

"Thinking about using water attacks, but there are drainage channels below too; external forces can't work, perhaps the only option is brute force breakthroughs."

Lin Hua and others shook their heads upon hearing this, as they indeed had no solution for it.

If they had a solution, there'd be no need to be this troubled now.

Zhou Yingting sighed upon hearing that.

"I haven't thought of a good solution either, I'll go over there to see the robots, see if I can figure something out."

Zhou Yingting stared at these things before him, pondering for a long while in his heart, but couldn't come up with a useful plan.

After much thought, he shook his head helplessly.

Seeing the situation this way, rather than studying these things here, he might as well try to study those robots over there.

Perhaps those robots might provide some inspiration for him.

Wu Yong didn't stop him after hearing this, only nodded when seeing Zhou Yingting leaving.

But just as Zhou Yingting was about to move, suddenly remembering something, he stopped and asked.

"By the way, I heard those robots also have their own weapons. Do you know if you've managed to capture any of their weapons?"

If their weapons are really powerful, wouldn't it be great to use them?

"Not all robots are equipped with those weapons. Previously, we saw those guys with weapons and got beaten up badly by them."

"We didn't get hold of those weapons."

Didn't they?

Upon hearing this, Zhou Yingting glanced at the other person and then turned to leave.

The other side said they didn't get any, but Zhou Yingting couldn't entirely trust them.

After all, they might have hidden the weapons for use as their trump card.

If someone tried something later, they could use these weapons to act as a deterrent.

However, with their statement of not having any, Zhou Yingting couldn't force it.

The robots they killed earlier, Zhou Yingting brought back a few, and he wanted to thoroughly research during this return.

When he previously tried to take out this kind of robot, the difficulty was excessively high; if he could find a way to ensure a kill, perhaps even ten thousand robots wouldn't be unsolvable.

Zhou Yingting approached the robot, leaned in to observe carefully.

The robots brought back this time were no different from before. If there was something different, it was probably that this time, Zhou Yingting had also brought back an Energy Core.

It's unclear whether using the Energy Core could lead to some different discoveries.

Upon leaving, he also took some Energy Cores in hand, which might be useful for research.

Zhou Yingting took out an Energy Core in his hand, and his gaze focused on the defunct robot.

If the contents were directly poured into this robot, who knows what the outcome would be?

Zhou Yingting stared at the robot in front of him, contemplating whether to take the risk.
