A moment after the crystals shattered, as the mist gradually dissipated.
At this time, rows and columns of neatly arranged infected creatures appeared on the streets below.
All the infected creatures stood in their respective areas, like soldiers awaiting inspection.
Zhang Chen did not have that much time for inspection.
These infected creatures appeared harmless now, but once they broke free from the Cleaners' control, they would become frenzied and bloodthirsty again.
Furthermore, these infected creatures were in a weakened state during the first stage of the apocalypse, but their abilities significantly increased in the second stage, even evolving new skills.
As the apocalyptic suppression was gradually lifted, they would undoubtedly become more ferocious when the ultimate apocalypse arrived.
If he didn't kill them, other survivors would eventually do so.
He might as well lighten the burden of future battles a little!
Zhang Chen took out the music player of this world, connected it to the speakers, and operated it simply.
Soon, rhythmic music began to play.
With the roaring music, Zhang Chen tapped his fingers to the beat.
As he tapped, endless zombie hordes surged forward.
As he tapped, boundless mist slowly steamed up...
Over an hour later.
As the last batch of infected creatures charged into the street and turned into shattered ice crystals.
The more than a million high-level zombies in the entire city were completely annihilated!
Ding! Automatic collection successful! Congratulations on obtaining [Energy Crystal] * 720,000 + 210,000 (30% chance of triggering Bright Blessing), [Mutated Gene Fragment] * 120,000, [Reinforcement Acceleration Fertilizer] * 2,350,000, [Evolution Gene Fragment] * 8,000...
[Talent Crystal] * 1, [Full Technology Blueprint 15] * 1, [Storage Ring Fragment] * 2315...
Other materials like sharp claws, Berserker blood, as well as low-level weapons, equipment, and blueprints, were countless.
Materials could be stacked in Zhang Chen's existing storage space.
As for the other weapons, equipment, and blueprints, Zhang Chen picked out some that felt valuable and stored them in Shirley's ring.
The rest were directly discarded on the spot.
Soon, supply boxes of various sizes appeared on the ground.
"Little White, synthesize!"
Zhang Chen called Little White over again.
This time, a total of 930,000 [Energy Crystals] were collected.
After Little White's synthesis, they were once again fused into 300 [Super Energy Crystals]. 30,000 were kept for consumption at the World Rare Item Auction.
Current remaining Super Energy Crystals: 690!
Hiss...
Zhang Chen needed 300*4 = 1200 [Super Energy Crystals] to upgrade to the third stage of an Advanced Metamorph.
He didn't expect to have 690 already, with the upgrade progress exceeding half?!
Indeed, the Singer skill was the true upgrade artifact.
With it, Zhang Chen's upgrades were incredibly easy!
The only drawback to upgrading like this was that it was a bit hard on the fingers.
The 98 Cleaners, by controlling the million-strong high-level zombie horde in batches, had consumed a huge amount of stamina.
All of them, with pale complexions, had returned to the [Giant Armor Transport Vehicle] to rest.
Zhang Chen then focused on the Cleaners, and prompts quickly appeared on them:
[Cleaner's current energy consumption is 90%, needing 12 hours 15 minutes 23 seconds to recover full stamina!]
[Cleaner's stamina recovery can be accelerated by feeding them crystals. 10 Energy Crystals reduce stamina recovery time by 1 hour!]
Consuming 10 [Energy Crystals] per hour, 12 hours would be 120 [Energy Crystals]. Multiplied by 98 Cleaners, it totaled 11,760.
Not much!
Consuming over ten thousand, and earning nearly a million in return, was a huge profit!
Zhang Chen took out over ten thousand crystals and distributed them to the Cleaners.
As expected, after absorbing the crystals, the Cleaners looked much better. At this moment, the prompts next to them changed to:
[Cleaner's current energy consumption is 1%, needing 12 minutes 11 seconds to recover full stamina!]
"Very good, everyone prepare to set off again!"
Zhang Chen called out.
"There's one more thing..."
Xu Ruina suddenly walked over and said hesitantly.
"Hmm? What is it?"
Zhang Chen was startled and asked.
"That... there are still a few infected creatures you haven't eliminated. Should we just leave them, or..."
Xu Ruina said, her gaze fixed on a corner of the street.
"There are still unkilled infected creatures?"
This surprised Zhang Chen.
After eliminating a large number of infected creatures, the scene was filled with mist, and he had only scanned the battlefield roughly.
The Giant Tanks and Wailers mainly stood on the road, while the Crawlers were mainly on the sides of buildings. All of these had been cleared.
He really hadn't paid attention to the corners.
There were still infected creatures categorized into the corners?
Xu Ruina tilted her head slightly and said, "It's them!"
As soon as she spoke, six strangely shaped infected creatures, with tentacles writhing like snakes on their backs, slowly crawled out from the corner.
"These are... Type IV Mutated Infected, Reanimators?!"
Zhang Chen almost forgot about them.
He remembered encountering them when he first entered the second stage of the apocalypse.
When one tentacle was cut off, two would grow, and when thirty tentacles grew, they would enter a berserk state.
Zhang Chen was very curious about what the berserk state looked like.
Each Reanimator had a different energy core location, and only by breaking the energy core could they be killed.
What was even more troublesome about this monster was that survivors it injured would directly turn into the same Type IV Mutated Infected.
It was like a virus, as long as they reached a place where survivors gathered, they could instantly replicate a large number of Reanimators.
"There's also a Type V!"
Xu Ruina controlled a larger Reanimator as it walked out of the corner.
This Reanimator had crimson eyes, its body covered with a thick layer of brown keratin, and its sharp claws left white scratch marks on the ground as it walked. Its strength was clearly far superior to other Reanimators.
Even more striking was that its back was covered with thirty tentacles, densely packed and extremely terrifying!
Furthermore, judging by the situation, the other Cleaners were unable to control this thirty-tentacled Reanimator at all.
Even with Xu Ruina personally intervening, she had to concentrate to control its movements.
Otherwise, she could only control it to stay in place, and it was impossible to make it queue up or anything like the other infected creatures.
It could be seen that the full-tentacled Reanimator was extraordinarily powerful!
At this moment, a series of prompts slowly appeared around the full-tentacled Reanimator:
[When the Reanimator's tentacles reach thirty, it is promoted to a Berserker, a Type V Mutated Infected, with significantly increased attributes and the same skills as a Reanimator!]
