At that very moment, the "Death Challenger" badge worn on Su Yue's chest began to shimmer faintly.

This signified that he had received a new mission challenge from the Order.

[Grim Reaper Challenger]: A special type of equipment that can be upgraded. It does not occupy an equipment slot. When equipped, it significantly increases the trigger rate of hidden quests and dungeons.

[Ding! The system has detected a lone wolf's strong killing intent towards Unit 731. A limited-time reward mission has been issued: "The End of Unit 731."]

[Brave warrior, are you willing to accept this mission and fight for justice?]

Mission Introduction: "Unit 731" was once synonymous with the bacteriological warfare production facility of the invading Japanese army. However, this name has now been awakened once more, reappearing in the world as a demonic unit produced by the Shiraishi family. Your mission is to do everything in your power to eliminate these mutated demons.

Mission Requirements: In the next ten minutes, you must complete as many kills as possible, using the fastest and most brutal methods. After the countdown ends, you will be fairly scored and awarded generous rewards based on your kill count.

Currently, there are 731 mutated demons remaining.

Task reward: ? ? ?

Task time limit: 10 minutes.

This is the first time Su Yue has triggered the hidden mission "Death Challenger".

"Accept the mission!" Su Yue frowned slightly. Did he even need to ask?

Su Yue glanced at the mission requirements: the fastest speed, the most brutal method, and the most kills—just what I wanted!

Having successfully plundered the talent, he naturally had no intention of continuing to contend with these demons.

Furthermore, kill the mutant in front of you.

Not only can it accumulate rich experience for him, but it can also earn him a considerable amount of battle merits.

Now, the "Death Challenger" badge is still actively issuing challenge missions to Su Yue. Isn't this just giving it away for free?

At this moment, Su Yue had already activated his Ghost King form.

Aside from being unable to summon the Chinese heroes within Hou Yi's Sun-Shooting Bow, all other abilities remain at their peak.

Furthermore, there are three newly plundered talents: "Craftsmanship", "Copycat", and "Reflective Monster".

He is ready to meet the upcoming challenges with this impeccable attitude!

The next second, Su Yue had a thought.

Activate the Demon King's Step! Activate the Wings of God!

With the enhancement of this death mark, his movement speed instantly surged to its maximum.

His speed was so fast that very few powerful individuals on Earth could even catch a glimpse of him.

[Ding! Due to the use of the "Ghost King Step" skill, the SS-level "Craftsman's Spirit" talent effect has been successfully triggered, restoring 25% of your stamina!]

That's right, using three skills triggered the mana regeneration mechanism!

Let's make it even faster!

Therefore, Su Yue continuously activated his silent skill while speeding along, further increasing his speed.

He seemed to transform into a ghostly shadow, moving freely across the battlefield.

[Silent]: Allows you to move to your opponent's side or even further away at a speed that is difficult for them to detect. The speed and distance traveled vary depending on the energy consumed.

Zongbu's teleportation ability is not subject to cooldown time.

The only drawback is that it consumes a lot of energy.

Even a powerful figure like Su Yue experiences a 15% reduction in his stamina every time he uses teleportation.

In theory, as long as luck isn't too bad...

Su Yue could then rely on the energy of "craftsmanship" to recover, thus theoretically realizing the possibility of infinite teleportation.

Although Su Yue possesses "max-level luck," it is unrelated to the trigger probability of his talent skills.

But when it comes to relying on luck, Su Yue has never been afraid of anyone!

After using it silently, Su Yue's trajectory could only be barely captured by the Order Keepers' live stream cameras.

Everyone else had been left behind by Su Yue's astonishing speed and rhythm.

At this moment, the only things that could pose a threat to Su Yue were those skills with lock-on tracking capabilities.

At half health, Mei Chuan Yifu anxiously searched for Su Yue's location.

At the same time, he frantically grabbed a handful of medicines and pills from his storage space, ready to stuff them into his mouth without a second thought.

However, would Su Yue give him a chance to recover?

Just as Kazuo Umekawa was about to swallow, that face that he had once loathed appeared before him like a ghost.

Immediately afterwards, a heart-wrenching pain came.

The outstretched hand was severed at the wrist by Su Yue, and even his throat was cut open by the twin daggers, splattering blood everywhere.

Colorful pills and medicines slid from the shocking wound on Umekawa Kazuo's neck and scattered all over the ground.

"Ah! Someone come quick! Kill Lone Wolf!" Mei Chuanyifu clutched his bleeding throat with both hands, screaming in despair and terror.

At this moment, the mutated troops, who had been frantically attacking the city gate, sensed their leader's urgent call.

They halted their advance and abandoned the crumbling city walls.

They turned and launched a frenzied charge in the direction of Su Yue.

In his original plan, Su Yue intended to defeat the mutants one by one.

However, when they appeared at the same time, he realized that this was a more efficient time.

With a thought, Su Yue saw the Fire Spirit Pearl on his bracelet immediately emit a faint red light.

The light spread rapidly, forming a pale red barrier that enveloped all the mutants.

[Fire Barrier]: Consumes Spirit Power to deploy a fire barrier. Within the barrier, fire element activity increases, all your fire attack damage increases by 50%, and the opponent's skill attack power decreases by 50%.

At this moment, the mutants surrounded by the barrier were like turtles in a jar, with nowhere to escape!
