The cheat system is useless, but I have the strongest living dad.

The ground was covered with body parts and bloodstains, mixed with many white crystal cores.

She remotely received a crystal core and tried to absorb it with her spiritual energy; the crystal core turned into white smoke in her palm.

It seemed she could absorb it. She absorbed five white crystal cores in a row and finally felt a trace of spiritual power restored.

Shen Yao: "Husband, these crystal cores contain spiritual energy. Let's absorb and replenish it quickly."

Feng Yu asked her, "You absorbed five, how much do you feel you've recovered?"

Shen Yao: "It has recovered a little bit. I estimate that it will be fully restored once it absorbs half of the crystal cores here."

Feng Yu: "You absorb first, I still have plenty of spiritual energy."

Shen Yao pinched her sleeve and raised her hand to wipe the sweat from his forehead: "There are so many crystal cores, let's absorb them together, hurry, we don't know when the next wave of zombies will come."

Upon hearing this, Feng Yu stopped being stubborn, and the couple quickly began absorbing the white crystal core...

Huo Die and Hu Yawu spent a long time groping around outside the mural. They touched every single star on the mural, but they were not sucked in, nor did they find the mechanism to break through the boundary.

They were pacing anxiously outside.

Hu Yawu: "Old Man Huo, how about we burn this mural too?"

Huo Die: "No, if this star array is burned, they will never be able to get out again."

"Ouch!" Hu Yawu slammed his fist on the mural. "What are we going to do now?!"

Huo Die carefully observed the star chart. The blue planet was still unusually bright, but it didn't react no matter how he touched it...

Two more waves of zombies arrived, absorbing one round of green crystal cores and one round of blue crystal cores.

Just as calculated, these crystal cores were just enough for both of them to fully recover their spiritual power.

The couple had just finished absorbing the blue crystal core, and before they could rest, a new wave of zombies arrived...

This wave of zombies is not as numerous as before, but their defense has obviously increased, and they are also more agile.

These mutated zombies are no longer foolishly rushing forward to their deaths; they can clearly distinguish attacks and dodge them.

Some mutated zombies also possess special abilities, such as suddenly leaping up and attacking them with water and fire.

At this moment, a zombie with bulging eyes stepped onto a car without a front end and leaped up to attack Shen Yao. It bared its teeth and claws, and as it leaped up, it sprayed blood and saliva, spitting a pillar of fire at Shen Yao.

Shen Yao instantly formed a hand seal and cast a wind wall, blowing the fire pillar back. The fire pillar charred the mutated zombie's dry hair, and a burnt smell filled the air.

Shen Yao unleashed five water spirit blades in quick succession, slicing off the mutated zombie's skull. The zombie's corpse fell to the ground, and the purple crystal core in its head exploded out.

Feng Yu continued her sword formation, and within its range, purple crystal cores burst forth from the zombies. Some of the smarter mutated zombies dodged the sword formation's range, climbed onto the roofs of nearby vehicles, and waited for an opportunity to leap up and attack.

These mutated zombies that know how to avoid the sword formation have clearly developed intelligence. Given more time, they will definitely grow into more advanced zombies.

Although this wave of mutated zombies was more agile, they didn't find it too difficult to kill them.

After the battle, all that remained on the road were rotting corpses and a pile of purple crystal cores.

Shen Yao sighed and stretched: "I'm exhausted, Yunhe, aren't you tired?"

Feng Yu had exhausted most of her spiritual energy and looked somewhat tired: "Don't worry, I'm not tired. Seeing you makes me feel less tired."

Shen Yao blushed slightly: "What time is it? You're still saying cheesy pickup lines."

Her husband's words are getting sweeter and sweeter.

Forget about flirting and banter, the couple quickly absorbed the purple crystal cores, preparing to face the next wave of zombies...

In the passageway between the second and third chambers of the underground palace, the blue planet on the mural shines brighter and brighter.

After observing and calculating, Huo Die finally came to a conclusion: "The two of them must be breaking the formation in the star map."

A low growl suddenly came from the third room. It was impossible to tell what kind of monster it was, but it sounded like there was only one.

Hu Yawu walked to the door of the third room: "Old Man Huo, should we go into the third room and deal with the monster inside?"

"No." Huo Die refused: "The underground palace is full of arrays and mechanisms. We don't know what kind of mechanism is connected to the star map at that door. Let's wait first."

Another wave of mutated zombies arrived on the highway. These mutated zombies were tall and had bluish-black skin.

They were smarter than the previous mutated zombies. They stopped at the scene of the car accident and roared loudly into the air: "Roar... Ha..."

Shen Yao aimed her golden finger at one of them, and fired a shot of golden light from it, piercing through the head of a mutated zombie.

The mutated zombie's head was pierced with a large hole, a precise headshot, but no crystal core was ejected.

It seems the cheat code shattered the crystal core as well. It appears that cheat codes are not suitable for dealing with mutated zombies.

"Dumb...dumb..."

Crows cawing in the air, and Shen Yao and Feng Yu looked up to see a flock of strange black birds flying towards them.

Shen Yao was shocked: "Oh no! Those are zombified mutated crows, even more difficult to deal with than mutated zombies!"

Feng Yu immediately formed a hand seal and cast a wind spirit shield: "The zombies below are not attacking, they must be waiting for these strange birds to force us to the ground."

If that's the case, then they definitely can't land. The couple exchanged a glance, rose into the sky, and simultaneously released a spirit net and a wall of fire, burning the mutated crows in groups.

Seeing that their plan had failed, the mutated zombies on the ground climbed onto the roof of the car and stared at them menacingly.

The crows in the sky had been burning for a long time, but the mutated zombies on the ground couldn't wait any longer. They piled up walls of corpses, and with the largest mutated zombie on top, they attacked them.

The mutated zombie stood on the wall of corpses, its arms transforming into two dark blue tentacles, which it used to pick up damaged vehicles and hurl them at them.

The vehicles thrown by the tentacles couldn't hit Shen Yao and Feng Yu at all, but they harassed them to no end.

After dealing with the mutated crows, Feng Yu looked sharply at the tentacle zombie and slashed its tentacles into several pieces with her Frost Sword.

"Frost Sword Formation, Ten Thousand Swords Unleashed!" The wall of corpses made it easy for him to use the sword formation. He controlled the sword formation better and better, and every attacking spirit sword was aimed at the skull of the zombie.

The horde of mutated zombies, piled up, was quickly wiped out.

Looking at the mutated zombies with their skulls shaved off under Feng Yu's sword formation, Shen Yao couldn't help but sigh, "It seems they've awakened some intelligence, but not many."

Feng Yu looked at her with affection and smiled: "We'll collect the crystal cores."

The crystal cores of this wave of mutated zombies are all red, blood red, and very translucent, making them look much higher quality than the previous crystal cores.

As Shen Yao absorbed the red crystal core, she felt a burning sensation in her spiritual root: "Yunhe, I feel my spiritual root is so hot, so scalding."

Feng Yu used her spiritual sense to examine the area and her face lit up with joy: "Yan Zhou, your spiritual root has expanded!"
