I have a space station

The dung beetles closest to the boundary began to dig into the soil, burrowing downwards.

One, two, three... more and more dung beetles started digging, raising an increasingly thick cloud of dust on the outer side of the boundary.

On the other side of the screen, Shen Tu Zheng Hao was on the phone when he happened to see the scene on the screen.

"Quick, get Dai Zheng here for me!" Shen Tu Zheng Hao immediately hung up the phone and shouted outside.

He didn't know if this iron tower could defend against attacks from underground.

Soon, Dai Zheng ran over.

"Report!" Dai Zheng shouted from outside the door.

"Enter!" Shen Tu Zheng Hao replied.

Dai Zheng walked into the command center.

"Dai Zheng, I'm asking you, can your iron tower block attacks coming from beneath the ground?" Shen Tu Zheng Hao asked anxiously.

"It can!" Dai Zheng nodded solemnly.

"Oh! That's good!" Shen Tu Zheng Hao finally breathed a sigh of relief upon hearing Dai Zheng's affirmative answer.

With the Queen Bee present, underground attacks were nothing to fear.

"However, Commander, this iron tower can't withstand threats from the air. If they launch an aerial strike, we'll have a hard time dealing with it," Dai Zheng added.

"That's alright, their artillery has already been destroyed by us. There shouldn't be any aerial threats in the short term," Shen Tu Zheng Hao said.

Dai Zheng nodded and said nothing more.

Since the dung beetles' attack was underground, it was impossible to visually assess the effectiveness of the attack at this time.

However, Shen Tu Zheng Hao felt much more at ease with Dai Zheng saying that everything was fine.

Meanwhile, Ling Tian was still waiting for the results.

He could only see dung beetles constantly burrowing into the ground, but no dung beetles emerged on the other side of the boundary. His intuition told him that this method might not work.

"Senior Brother..." Ling Su ran in anxiously.

"Did it fail?" Ling Tian was already mentally prepared.

"Yes! It's still the same, the dung beetles that get close to that boundary disappear inexplicably," Ling Su nodded and said.

"Have you tried digging the hole deeper?" Ling Tian asked.

"We tried, it didn't work," Ling Su replied.

Ling Tian fell into deep thought again.

This was completely different from what he had imagined.

He had originally guessed that the invisible boundary might be a protective shield formed by the glowing iron tower. If that hypothesis held true, then the shield should be like a pot lid, covering everything from above.

Although he was extremely unwilling to believe that such technology existed in this world, capable of creating a protective shield out of thin air, this explanation was the most reasonable given the scene before him.

However, reality negated his hypothesis.

This protective shield could actually penetrate underground, which was truly incomprehensible.

But in reality, he had fallen into a misunderstanding, and his line of reasoning was completely wrong. There wasn't even a protective shield there at all.

Even that iron tower was just a prop to mislead others.

The same was true for the conflict between the Red Lotus Sect and the Red Robe Sect in Mo Prefecture last time. The glowing aircraft or iron tower in the middle were only there to make it easier for people to understand the disappearance of the zombies and these dung beetles, and served no other purpose.

Clearly, everyone who didn't know the truth had been led astray.

Everyone believed that the iron tower was blocking the dung beetles' advance.

"Damn it!" Ling Tian slammed his fist on the table.

That invisible protective shield had tightly surrounded the Huaguo army in the middle, and he couldn't think of a way to deal with it for the time being.

"Senior Brother, why don't we try attacking from the air?" Ling Su suggested.

She didn't have much confidence when she said this, she was just saying it out of concern because she didn't want to see her Senior Brother so distressed.

"Even the underground is so heavily defended, it's even more impossible to attack from the air," Ling Tian shook his head and decisively gave up trying.

There was another reason why he was unwilling to try.

All the artillery stationed in Bato City had been sacrificed by him as bait for the Huaguo army. Otherwise, wouldn't those artillery pieces have been able to carry out aerial strikes?

But he couldn't admit that he had miscalculated this step, because his pride was too strong.

Ling Su nodded and didn't think much about it.

Ling Tian thought so, and so did she.

According to their normal understanding, the underground must be more difficult to defend than the air. If the protective shield wanted to penetrate underground, it would definitely require more energy. There was no reason why the underground was so heavily defended while the air was not.

If they knew that the iron tower was just a prop and there was no aerial defense at all, wouldn't they be so angry that they vomited blood?

Ling Tian was extremely anxious at this time.

He had painstakingly lured the Huaguo army to Bato City and successfully surrounded them. But he just couldn't take this piece of meat that was already in his mouth. How could he not be anxious?

"Then, why don't we try using the Giant Ant Legion?" Ling Su asked.

The Giant Ant Legion that Ling Su was referring to was the Armored Ants.

"They also can't get in... what, do you mean attacking directly from the outside?" Ling Tian was about to say they couldn't get in, but he suddenly realized what she meant.

"That's right. But I don't know if that boundary can defend against bullets," Ling Su said uncertainly.

"It doesn't matter, we can try it. Go and do it quickly!" Ling Tian urged.

They would soon realize how fortunate this decision was.
