Tong Xin and the others couldn’t immediately determine what the black staining substance was, so they had no choice but to experiment slowly.

After some thought, Ye Liuyun summoned the two half-beast corpse demon puppets.

"I’m planning to cut two pieces of fabric to wrap around the areas where their consciousness is stored, to protect them from attacks. Do you think that would work?" Ye Liuyun asked Tong Xin.

"Huh? That might work. But if you force it in, won’t it kill them? Their whole bodies are stiff as iron—where would you even start?"

Though Tong Xin found the wolf-headed half-beast corpse demons repulsive, he still couldn’t bring himself to harm them.

"I have a way. As long as it’s feasible, that’s good enough."

Ye Liuyun drew his silent dagger and sliced two pieces from the black umbrella. Then, he began performing the procedure on the half-beast corpse demon.

Since the creature felt no pain, Ye Liuyun started with its left eye.

Using his golden pupils to pinpoint the exact spot, he removed the demon’s left eye, then carefully wrapped the fabric around the area where its consciousness was stored using his advance energy energy. After that, he reinserted the eye, dripped some Life Spring Water onto it, and fed the demon a drop to aid its recovery.

Half a day later, the half-beast corpse demon was as good as new.

Tong Xin could only shake his head in disbelief. "That actually worked!"

"Mm." Ye Liuyun nodded. "Wouldn’t work on a living person, but for this? Perfect."

Pleased with his handiwork, Ye Liuyun repeated the process on the other half-beast corpse demon before letting them rest and recover.

Now, these two puppets were truly invulnerable—capable of withstanding both the white and black beams from the Three-Eyed Otherworlders.

Afterward, Ye Liuyun had Lan Jia begin training them in spatial powers.

Both puppets possessed relatively weak spatial powers, as their innate spatial abilities had been limited even before they were refined into puppets.

Mu Xi had never trained them in any special abilities, simply relying on their brute strength in combat. But now, with Ye Liuyun’s divine sense controlling them, their spatial powers were rapidly improving.

Ye Liuyun didn’t hesitate to replenish the energy required for their spatial worlds, though he usually restricted them from using it freely. His reason for modifying and training them was simple—he was pinning his hopes on these two. In terms of raw power, they were the only ones who could stand a chance against Mu Xi.

When the time came, with the addition of the Demon-Sealing Stele, the Demon Vine, himself, and his doppelgänger, they could engage Mu Xi in a six-on-one battle—perhaps even eliminate her.

Meanwhile, Qiong Qi had thoroughly studied the alien race’s formation and informed Ye Liuyun, "I can get you inside without disrupting the array."

"That’s perfect! We can take out some of the aliens first and reduce our losses in the final battle," Ye Liuyun exclaimed, thrilled by the news.

However, the number of aliens within the city was substantial. To avoid alerting them prematurely, they would have to rely on stealth and assassinations upon entry.

Ye Liuyun immediately summoned the Demon Vine, the Demon-Sealing Stele, Phantom Hand, Xenocide, Xuanwu, as well as the alien warriors Mu Lai and Blue Armor.

Still, he felt the team was insufficient, so he contacted Liu Kui and borrowed Mo Sha and a few former Black Kill assassins.

Soon, Mo Sha arrived with two former Black Kill members to report to Ye Liuyun.

"For smoother communication and coordination, I’ll need to reinforce my control over you," Ye Liuyun explained. 𝘧𝑟𝑒𝑒𝘸𝘦𝘣𝑛𝑜𝘷𝑒𝓁.𝘤𝘰𝓂

These individuals had already been marked with his slave seals, but to his surprise, they were fully cooperative. Having witnessed Ye Liuyun’s strength firsthand, they trusted his leadership completely.

"Thank you for your trust!"

Ye Liuyun also expressed his gratitude and implanted slave marks in them, then transmitted information about the number and strength of the alien races within the city.

He even lent the invisibility cloaks to Mulai and Lan Jia to prevent them from revealing their positions.

Once the assassination squad was assembled, Ye Liuyun selected a city to strike.

Qiong Qi, also draped in an invisibility cloak, joined Ye Liuyun and the others in the operation. His task was to first dismantle the defensive formations, allowing Ye Liuyun’s team to infiltrate, and then alter the outermost layer of the formation to trap the aliens inside, preventing their escape.

Meanwhile, Yu Xiaofeng had arranged for five hundred Falcon ships to stand by in the void, ready to provide support at any moment.

When they arrived outside the city’s defensive formations, Ye Liuyun sent a mental message to Qiong Qi: "Begin!"

Without delay, Qiong Qi set to work. The city was protected by seven layers of formations, and Qiong Qi needed to breach each one.

Cloaked in invisibility, Qiong Qi remained unseen by the others, who could only wait in silence.

Ye Liuyun couldn’t store them all in his spatial world, as releasing them later might alert aliens sensitive to spatial fluctuations.

His clone hovered in the air, monitoring the movements of the aliens within the formations to ensure none suddenly emerged and stumbled upon them.

Qiong Qi’s mastery of formations had improved significantly in recent times, and he swiftly breached all seven layers, relaying the locations of the gaps to Ye Liuyun.

Ye Liuyun then shared these locations with the team, instructing them to enter one by one. Once inside, Qiong Qi immediately set about modifying the outermost formation, reversing its defensive orientation.

After entering, Ye Liuyun and his clone used their golden pupils to scan the entire city, pinpointing the aliens’ positions.

He then transmitted this information to each member through the slave marks and assigned targets, prioritizing the three-eyed aliens for assassination.

The team dispersed, moving cautiously through the city, wary of detection. Though their progress was slow, it was safer—given the abundance of aliens with strong spatial awareness within the walls.

Two hours had passed, yet most of the group still hadn’t made their move.

But Ye Liuyun and his doppelganger had already eliminated four of the three-eyed aliens. Thanks to their mastery of spatial energy, they could move stealthily without alerting their targets. With swift precision, they annihilated the aliens’ souls using dark energy beams, then discreetly stashed the corpses away—all without a hitch.

Mulai had also taken down two targets in quick succession. Cloaked in his invisibility mantle, he slipped past detection with ease. Once close enough, he struck without hesitation, unlike the others who had to bide their time for the perfect moment.

Seizing an opportunity, Ye Liuyun also unleashed the Demon Vine, sending it to attack from beneath the earth.

Creeping through the underground, the Demon Vine moved with caution—yet still far quicker than the other warriors. In no time, it claimed two more kills, piercing the aliens’ skulls with its newly honed white energy beams before dragging their lifeless bodies into the soil.

Only the three-eyed aliens’ distinctive orbs were left behind.

Ye Liuyun hadn’t insisted the others prioritize collecting the eyes. Safety came first—if they could retrieve them easily, fine; if not, so be it.

Before long, Mosha, Huanshou, and Lanjia each made their move, wiping out the remaining three-eyed aliens. Mosha and Huanshou gathered the corpses, while Lanjia obliterated his targets with spatial collapse, leaving no remains to collect.

Ye Liuyun didn’t mind.
