A large city in the United States is surrounded by overwhelming zombies at the moment, and the defense line arranged by the American military and police instantly became fragmented under the impact of the zombie horde.

It's not that the American military and police are too weak, but the zombie hordes have evolved too fast, with hundreds of thousands of mutated birds in the air to cover, countless terrifying monsters underwater, and nearly a million zombie armies on land.

"Buzz ......"

The terrifying sound of flapping wings echoed in the air, and hundreds of thousands of elite troops of the United States of America instantly became scattered and fled under the impact of the terrifying zombie hordes and mutant birds.

I saw that where the zombie hordes and mutant birds passed, there were endless wailing sounds, and countless American people fell under the zombie tide, either gnawed clean by the zombies, or assimilated into a member of the zombie army.

"Retreat!"

Although the military top brass ordered a retreat, it was obviously too late, but it was a group of mutant birds that suddenly rushed down from the sky, frantically attacking the soldiers.

There are also countless huge monsters that have emerged from all corners and wantonly killed humans.

"Whew!"

However, at this moment, hundreds of streamers suddenly crossed the sky, and it was the monks of the Heavenly Dao Alliance who had received Li Ge's order to help the American side clear the zombie horde.

Flying swords slashed through the void, rolling heads fell to the ground, and thousands of zombies fell in an instant.

"It's ...... them again"

In an apartment somewhere in another city, Jiang Xuan gritted his teeth and looked at the virtual screen.

This is already the third batch of zombie army, and if it continues like this, I am afraid it will not be long before all zombies and mutated creatures will be wiped out.

It's just that Jiang Xuan couldn't figure out how this group of people appeared, and it seemed that they were specifically aimed at him.

"System, what the hell is going on, is there really an immortal cultivator in this world?"

Jiang Xuan almost roared and questioned the system, but unfortunately, the system didn't like him at all.

As for why it is said that it is an immortal cultivator, I haven't seen those people who can fly with a sword, and they can also kill zombies with a sword, which is exactly the same as the sword fairy in myths and legends.

Jiang Xuan is just a foreign student, and he was not born and raised in the United States, so he naturally understands the myths and legends of China.

"How am I going to get the job done if I continue like this?"

Jiang Xuan's brows almost furrowed, the task given to him by the system was to infect all humans on the earth into zombies, and he was only given ten years, if he couldn't complete the task when the time came, he would be wiped out by the system.

"System, what virus can infect those people?"

Jiang Xuan suddenly thought of an idea, that is, to infect all those immortal cultivators into zombies.

As long as it is infected by the virus and becomes a zombie, or other mutated monsters, then Jiang Xuan can manipulate it through the system.

Otherwise, how did you think those zombie groups were formed, and those mutated birds would also support the zombie groups in the air, all of which were secretly manipulated by Jiang Xuan.

"Ding!"

As soon as Jiang Xuan's words fell, a prompt sound sounded in his mind, and then a list appeared on the virtual screen.

"Virus H105 can infect monks in the foundation stage, virus H106 can infect monks in the Jindan period, and virus No. 107 can infect monks in the infancy stage......"

But the next moment, Jiang Xuan's face darkened, although he was able to redeem those viruses, the exchange points were too high.

It takes 1 million points to redeem the H105 virus, 10 million points to redeem the H106 virus, and 100 million points to redeem the H107 virus.

However, one thing can be proved from the side, that is, those people are really immortal cultivators, and I didn't see that even Zhuji, Jin Dan and Yuanying have several familiar names come out.

Jiang Xuan had also seen a lot of Xiuzhen before, and he was naturally extremely familiar with the so-called Zhuji, Jindan and Yuanying.

In the past, Jiang Xuan thought it was all made up, but he didn't expect that there really was a cultivation system in reality, could it be that those were written by immortal cultivators in the first place?

"Exchange H105 Virus!"

After consuming one million points, Jiang Xuan suddenly felt a pain, you must know that those are the points he has accumulated with great difficulty.

Originally, he planned to keep the ones he had strengthened, but now he was back before liberation.

The virus that Jiang Xuan first spread was the H104 virus, and later exchanged the KIRE virus in order to make the zombies evolve faster.

However, the H104 virus was not redeemed by Jiang Xuan himself, but was drawn from the newbie package.

"But how do you spread the virus?"

Looking at the green glass bottle in his hand, Jiang Xuan suddenly frowned, you must know that those people are all cultivators, I am afraid that he will be discovered as soon as he gets close.

With the strength of those cultivators, he could kill him with a casual urge of the flying sword, and although he had teleportation skills, Jiang Xuan still didn't dare to take risks.

"There it is!"

Jiang Xuan planned to manipulate a zombie and let the zombie approach the cultivator with the virus.

The next moment, Jiang Xuan's figure disappeared, appeared in a city that had been infected, opened the system to control a zombie, and hung a glass bottle containing the virus around the zombie's neck.

Then Jiang Xuan manipulated the zombies and slowly moved towards the center of the city, because in the center of the city, there were many cultivators there to clear the zombie group.

"I wonder what those cultivators will become after they become zombies?"

Jiang Xuan was very much looking forward to this scene, the cultivator was already very powerful, and if he turned into a zombie, he would definitely be very powerful.

Under Jiang Xuan's manipulation, the zombie slowly walked to the center of the city, but before Jiang Xuan could manipulate the zombie to break the glass bottle, he saw a white light falling from the sky and cutting off the zombie's head.

"Damn it!"

Jiang Xuan was suddenly taken aback, just now he shared his senses with the zombies, and he naturally felt the same way when the zombies were beheaded.

However, seeing that the glass bottle containing the virus was not broken, Jiang Xuan had to manipulate another zombie nearby, picked up the glass bottle and left it on the ground.

"Click!"

As the glass bottle fell to the ground, an invisible gas diffused.

"What's going on?"

It just so happened that there was a foundation building monk in the sky, and after inhaling the virus, he suddenly noticed a trace of abnormality.

Cultivators are not ordinary people, so they can naturally detect the abnormalities of their bodies.

However, even if you are infected with the virus, it will take a long time for the virus to break out.

"Successfully infected one!"

Seeing that a cultivator was infected through the system, a sneer appeared on the corner of Jiang Xuan's mouth.

There are only one and two, and I believe that soon those cultivators in the foundation building period will all become members of the zombie army under his command.

The only thing that made Jiang Xuan jealous was those Jindan stage monks and Yuan Infant stage monks.

Maybe it's because the health level is too high, and if you want to infect them, you need a higher-level virus.

But whether it is the H106 virus or the H107 virus, he can't afford to exchange it now.
