To save this world, the capable people of this world tried everything they could think of.
For example, they established corpse burning squads. As long as a corpse was found, it was burned on the spot. From cities to the wilderness, members of the corpse burning squads were everywhere, penetrating every corner.
Human corpses, animal corpses, all were burned to ash.
But the ocean quickly gave the humans of this world a surprise. People despairingly discovered that although burning corpses could slightly slow down the increase of corpse qi, the Zombie fish in the ocean increased at an astonishing rate, and the tactic of burning corpses was clearly ineffective in the ocean.
In addition, many Alchemists also joined forces to develop corpse qi conversion devices, intending to convert corpse qi into harmless energy. After hundreds of years of research, they succeeded, but the conversion efficiency compared to the speed of corpse qi growth was completely insignificant.
What was more fatal was that this conversion also required a large amount of mithril, making it unsustainable.
Some people also thought of taking the forbidden fruit to become a race that could devour corpse qi, but the result was that they turned into a Zombie.
There were also people who, by taking the forbidden fruit, wanted to become a non-Zombie race that could devour corpse qi. They succeeded, but they turned into ghouls, monsters even more brainless than Zombies.
To save this world, everyone was like headless flies bumping around everywhere, daring to try any method.
But without exception, after sacrificing a large amount of manpower and resources, all methods ended in failure.
...
...
Yu Xian and Zhang Shou did not stay in front of the strange tree for too long.
After figuring out the origin of the tree, the two continued forward, aimlessly exploring the unknown world.
That tree was named the Tree of Despair. In fact, it was also a product created by the humans of this world to save the world. It could absorb corpse qi to grow. Originally, people had high hopes for it, hoping it could improve the increasingly harsh environment.
As a result, the Tree of Despair, just as its name suggested, only brought a more despairing future to humanity.
After its seeds landed, they would release a large amount of corpse qi, attracting more Zombies. When the Zombies instinctively absorbed the corpse qi, the seeds would take the opportunity to follow the corpse qi into the Zombie's body, eventually taking root and sprouting inside the Zombie's body, growing using the corpse qi within the Zombie's body.
When the Zombie was drained and fell, the seeds would burst out of the body, take root and sprout in place, and grow green, rope-like vines to capture approaching Zombies.
Although it could kill Zombies, it had itself become a part of the corpse qi growth cycle, only accelerating the world's destruction.
It is worth mentioning that there should be many Trees of Despair in this world, otherwise if all plants died out, the oxygen would become increasingly thin, and Yu Xian and Zhang Shou would not be able to feel it.
Sure enough, two hours later, they saw a forest of Trees of Despair.
The Tree of Despair was very easy to recognize. The trees were always covered in corpses, all sorts of corpses, diverse and varied, including humans and animals. Without exception, they had all become Zombies.
"Yu Xian, if our world also becomes like this in the future, what should we do?" Zhang Shou asked with a heavy expression.
His gaze fell upon the corpses hanging from the Trees of Despair. Among the many hanging Zombies on the outskirts of the forest, several young Zombies were particularly striking. Some looked only three or four years old, and some even looked only one year old, still wearing diapers.
"I don't know," Yu Xian shook his head.
All along the way, he had actually been thinking about how to save the world.
But he was very clear about an undeniable fact: no matter how powerful his Super Brain was, it was impossible for it to compare in wisdom with the people of an entire world.
The humans of this world had almost tried every method they could think of, but the results were too despairing.
Boom!
At this moment, a huge sound came from a distance.
Yu Xian and Zhang Shou immediately looked in the direction of the sound, only to see sword light flashing in the distance, and a large number of Zombies instantly turned to ash.
"Someone?!" Zhang Shou exclaimed excitedly.
Yu Xian immediately lifted Zhang Shou by the collar behind his neck, easily jumped onto the back of the Dragon-shaped Perfect Creature, and ordered the Dragon-shaped Perfect Creature to advance at full speed.
With a low roar, the Dragon-shaped Perfect Creature immediately advanced at full speed. All the Zombies blocking its path were crushed by it.
A moment later, Yu Xian and Zhang Shou, sitting on the dragon's head, saw a ruin. Through the surrounding broken eaves and walls, they could vaguely tell that this should have been a city, but now even its outline was very blurred.
In front of this ruin, a Zombie holding a blood-red greatsword and wearing tattered armor stood motionless, completely unresponsive to Yu Xian and Zhang Shou's approach.
Although this Zombie did not look burly, it had an indescribable aura, as if in front of it were a thousand armies and ten thousand horses, and behind it were the lights of ten thousand homes.
A sword, yet it was like a gate.
Soul-stirring.
Yu Xian took a deep breath, immediately used Appraisal Skill on this Zombie, and at the same time prepared himself mentally to teleport away at any moment.
A moment later, he saw the Zombie's attributes:

------
Strong!
Yu Xian felt that this Zombie was even stronger than the Xing Tian Zombie King.
He swallowed, and quickly ordered the Dragon-shaped Perfect Creature to retreat.
However, the Martial Extremes Zombie King clearly had no interest in him and Zhang Shou. It still stood rooted to the spot, holding its sword with both hands, its eyes fixed on the front, seemingly guarding the ruin behind it.
Yu Xian, recalling the words 'Sacrificing oneself for the country, a true hero', vaguely guessed the situation of the Martial Extremes Zombie King in his heart. He took a deep breath, did not disturb this admirable strong person further, and drove the Perfect Creature to go around.
Many strong people in this world had fled, but not everyone would flee. When danger struck, there were always people who would stand out, using their own spines to hold up a sky for the people behind them.
Even in death, they died standing tall and fighting honorably.
