Their actions were all seen by Zhang Yi, who instantly understood their intentions.

"Trying to forcefully block my attacks to create an opportunity for their subordinates to enter the Nine-Story Demon Tower?"

"Hmph, it's not that easy!"

Zhang Yi flipped his hand and retrieved a small black box from his Dimensional Space.

The box was slightly larger than a palm, engraved with a skull.

Even when Zhang Yi took it out, his movements were extremely cautious, afraid it might accidentally fall.

Although the safety measures were very thorough, just thinking about its composition, Zhang Yi unconsciously slowed his movements.

He opened the box, inside were bullets that looked almost identical to Sacred Silver bullets in appearance, except each bullet had a small skull emblem on it.

Zhang Yi loaded a bullet into Thunderbolt and then aimed at the Nine-Story Demon Tower.

He didn't need to aim at Gao Changkong or Lancelot; those two could dodge his bullets.

Attack what they must defend, killing their subordinates was enough!

"Move out!"

At the command from Gao Changkong and Lancelot, Lancelot immediately prepared to intercept Zhang Yi's bullet.

Several superhumans from the Knights of the Round Table and the Garuda Legion acted without hesitation, swiftly using their abilities to rush toward that entrance.

A height of a thousand meters didn't require much time for them.

Zhang Yi's bullet locked onto one of them, and he quickly pulled the trigger!

Boom!!

The tremendous roar made the surrounding buildings tremble. The bullet, enhanced by superhuman ability, arrived in an instant, heading straight for Lamorak, the Shining Knight of the Knights of the Round Table.

Lamorak didn't even glance at it. Her speed was completely insufficient to dodge this bullet, but she believed the vice-captain would block it.

Sure enough, between the bullet and Lamorak, Lancelot leaped into the air.

His left hand summoned a pitch-black holy shield, with a Christian cross in the center, though at this moment, the cross bore a deep scar, symbolizing rebellion.

In his right hand was the conquest sword Kangge'er, and in his left, the protective shield Grad.

The protective shield blocked in front of the bullet. In just an instant, the collision occurred.

Then, an extremely dazzling white light erupted violently before him, instantly devouring everything around!

Feeling this power, Lancelot's expression changed instantly.

"F**k!"

The immense force actually sent him, mid-air, flying backward hard. The shockwave swept through the air, not completely blocked by Lancelot.

The terrifying gale also impacted the others' bodies, making it difficult for them to continue forward.

"Boom!!"

Lancelot was slammed into the Nine-Story Demon Tower, creating a deep crater in the massive rock.

"What??!!"

No one expected this outcome.

Lancelot actually couldn't even block one bullet from Zhang Yi?

Seeing this situation occur, the operation had to be forcibly canceled.

If they took a few more bullets from Zhang Yi, even if Lancelot and Gao Changkong could withstand them, they would inevitably get injured.

Having just arrived at the Demon Kingdom, they certainly didn't want to end up like that.

Lancelot jumped down from the rock wall, his eyes fixed intently on Zhang Yi's direction, somewhat angry, but more excited.

"The bullet he used is problematic!"

That explosive power was clearly not a superhuman ability, but the bullet's own power.

Gao Changkong frowned. "Impossible! No matter how powerful a bullet is, it relies only on the kinetic energy from gunpowder propulsion."

Lancelot took a deep breath. "I'm not sure either. It might be some specially made weapon. After the Apocalypse, superhuman abilities rose. Only superhumans who rely more on weapons for combat would spend enormous effort on this."

Lancelot guessed correctly.

Zhang Yi never focused solely on improving his own superhuman ability index.

He would try every possible method to comprehensively enhance his strength.

Strategy, weapons, helpers, battle beasts—any means he could use, he would try.

And the bullets he used were one of them.

The technology for this bullet came from the Northern superpower nation Suirimens, which existed a century ago.

Its name was nuclear bullet.

It used the extremely rare transuranic element californium, with radioactivity far exceeding uranium.

One bullet, after exploding, released an equivalent yield of 7 tons of TNT.

According to pre-Apocalypse technological levels, manufacturing one such bullet cost over a hundred million.

Even with Lu Keran's help, Zhang Yi only had twenty such bullets in his possession.

As for the raw materials, he obtained an extremely precious small portion through exchanges with Blizzard City.

Zhang Yi remained expressionless, continuing to take out another bullet worth over a hundred million and loading it into the chamber.

Even superhumans at the Epsilon level would get injured trying to block its power head-on.

Of course, superhumans with special abilities were exceptions.

For example, Zhang Yi's ability could absorb it, or someone like Li Changgong, who could ignore all physical laws and cut through anything.

To take it head-on without injury, unless one was a superhuman with an extremely formidable physique, at least reaching Black Chariot-level might make it possible.

"I really want to kill both of them in one go!"

Zhang Yi narrowed his eyes and said calmly.

But that was impossible. Unless it was an assassination, openly shooting could at most severely injure both.

He stopped in time to prevent the other side from adapting to his bullet's power.

Deterrence was enough; he just needed to stop them from entering the Nine-Story Demon Tower's interior.

On the other side, Lancelot and Gao Changkong were also at a loss.

Gao Changkong teased Lancelot. "Isn't Britannia's industrial technology very advanced? Don't you have any powerful weapons to bring out and use?"

Lancelot said irritably, "You think I don't want to? I do have some, but the problem is—"

He took a deep breath, quite helplessly saying, "We can't bring them out!"

Fighting across a continent, they simply couldn't carry large quantities of weapons, let alone heavy weapons.

This was one of Zhang Yi's greatest advantages as a spatial-type superhuman.

Others fought wars of attrition, while he fought wars of equipment.

Often, his opponents hadn't even touched the hem of his clothes before being worn down to the point of vomiting blood.

In the time Zhang Yi bought, Liang Yue had already led Fatty Xu, Old You, Mu Yan, and others to begin sweeping through the Ancient City.

Important information was also easy to find.

The Ancient City was relatively backward. Most houses were made of stone. Commoners' houses were low and small. The taller, better-looking houses belonged to nobles and government offices.

Currently, there weren't many experts left in the city. The group moved unhindered, collecting useful information everywhere.

Soon, they found an aged-looking library in the Demon Kingdom's Ancient City.
