After explaining the emotional line of the hero and heroine through the ninth and tenth volumes, the next is another climax of the story: the invasion of the demons.

It is said that at the western end of the Xiuzhen Continent, there is a mysterious and terrifying race, like a man and a beast, with sharp teeth and claws, purple skin, dark green blood, ferocious nature, and likes to eat human flesh, so it is called the demon race.

Hundreds of years ago, the demons invaded Middle-earth on a large scale, and corpses were everywhere they went.

Later, under the joint counterattack of the people, soldiers and cultivators of various continents, the demons were finally driven away after paying a heavy price for casualties, and only then was the foundation of the human race preserved.

Now, hundreds of years have passed, and the demons have invaded again. This attack is no small feat, more than it was hundreds of years ago.

In order to resist this demon invasion, the governments of various continents once again united everyone to resist the demons.

After the battle between man and demon began, the battle was extremely fierce.

The demons are born with great strength, and they are extremely fast, with thick skin and thick flesh, and ordinary people can't beat them at all. An ordinary demon soldier needs at least three well-trained Terran soldiers with weapons in their hands to be able to fight, and the strength of the two sides is very different.

At the beginning of the battle, the Terrans were overwhelmed and had little to fight back, relying on the advantages of the city to defend.

But even so, it was still unable to resist the attack of the demons, and one city after another fell.

Once the city was captured, the officers and soldiers and the people inside were miserable, and all of them became the rations of those monsters.

After those monsters eat people, they like to tie the skulls of their victims to their bodies as trophies, which is even more terrifying to watch.

At this critical juncture, tens of thousands of cultivators suddenly joined the battlefield, which immediately turned the entire tide of the battle.

Although the demons are very strong, the cultivators are not only strong in martial arts, but also have all kinds of powerful magic weapons, and when they join the battlefield, they quickly beat the demons to the ground.

Among these tens of thousands of cultivators, in addition to the righteous people, there are also people from the evil sect.

It turned out that the cultivators of the two factions of good and evil also knew the truth of cold lips and teeth, and knew that if the demons were really allowed to occupy Middle-earth, the entire world would be reduced to a Shura hell at that time, and even those of them who cultivated the truth would not be spared.

Thus, for the first time in hundreds of years, the cultivators of the two factions put aside their disputes and grudges and joined the Anti-Demon Alliance to work together.

Because of the addition of the cultivators, the morale of the Terran soldiers was greatly boosted, and they finally regained the two fallen cities.

Just when the human race was about to carry out a large-scale counterattack, a similar cultivator suddenly appeared on the demon side, and the situation was suddenly reversed.

Those demon cultivators were more like war shamans than cultivators.

Through a series of intricate spells and rituals, they can make the entire demon army stronger and more ferocious.

Although the cultivators are powerful, after all, the number of people is limited, and compared to the army of millions of demons, it is simply a cup of salary.

In addition, there is a war shaman who can bless the entire demon army with special effects, which makes the situation of the war between humans and demons even less optimistic.

Ji Zheng, who was originally compiled by both good and evil, didn't want to care about this matter, but because of Wan Lingyin's relationship, he couldn't ignore it.

Because Wan Lingyin's original master, Lingyun Zhai, also joined the Anti-Demon Alliance and became one of the main forces of cultivators against the Demon Clan.

Although he was expelled from the school, Wan Lingyin, who grew up in Lingyunzhai since he was a child, never let go of his master and uncle and all the sisters of the same sect.

Wan Lingyin is different from Ji Zheng, Lingyunzhai did not feel sorry for her, but she was driven away after stealing medicine and violating the rules of the sect first.

The master didn't take her life, but just abolished her cultivation power, and he was already on the open side.

Wan Lingyin saw that as time passed, more and more of her former classmates and sisters were seriously injured or even died on the spot on the battlefield, her heart was like a knife, but she didn't dare to tell Ji Zheng, and she suffered every day.

Although Ji Zheng didn't say it explicitly, he saw everything in his eyes, so he finally decided to meddle in things.

One night, he left a letter for Wan Lingyin while she was asleep, and then he didn't even bring the tiger demon, so he went out alone.

The reason why he didn't bring the tiger demon was because he thought that once he couldn't come back, Wan Lingyin would have to rely on the tiger demon to protect him in the future.

And what he has to do is to assassinate those demon shamans and increase the chances of victory on the side of the Terran army.

In fact, there have been cultivators who have wanted to do this for a long time, but none of them succeeded, and all of them died on the way to assassination.

Since the demon shaman has a great effect on the demon army, the demon side will naturally strictly protect these important people.

Those who stayed by their side were the strongest elite warriors in the clan, and if they fought alone, they could even tie with the cultivators of the foundation building period, which showed their strength.

Moreover, the camp where the shaman lives is the center of the demon army, which is protected layer by layer, and even mosquitoes can't fly in.

Under such a tightly guarded situation, it would be difficult for even the top two top masters in the rivers and lakes to blend in, let alone cultivate to an average cultivator.

At this time, Ji Zheng was not a top high school, and he had just entered the Dan period.

Normally, judging from his cultivation behavior of entering the Dan stage in his early twenties, he was already a very rare leader among the younger generation of cultivators.

In fact, his cultivation improved so quickly, it had nothing to do with his talent, mainly thanks to that Gathering Spirit Bead.

The biggest effect of this cultivation treasure is that it can gather the aura of heaven and earth, so that the cultivator can easily inhale the gathered aura of heaven and earth into his body and use it for his own use, so his cultivation will be a thousand miles in a day, and he will enter the stage of knotting at a young age.

Although Ji Zheng is not a top master, he knows very well that assassination is completely different from head-to-head combat, and his own cultivation is not the most important, it mainly depends on his brain and patience.

After he arrived at the demon camp, he did not rush in immediately, but first observed and studied the movements of the demon army.

After a few days of careful observation, he devised an assassination plan that was risky but had a high success rate.

He first assassinated a lone demon soldier outside the camp, and then used the surgical anatomy knowledge he learned from the ghost doctor to cut the demon soldier's corpse open from the abdomen, and then dug out all the internal organs and bones, leaving only a layer of skin and muscle tissue.

Next, he "weared" this leather bag and pretended to be an ordinary demon soldier, and took advantage of the lack of vision at night to infiltrate the camp where the demon shamans were located.

He didn't go straight to the barracks where the shaman lived to assassinate him like the other cultivators, but instead blended into the special water room that the demon shaman usually used for toilets and washing.

Once there, he hid in a tank and waited patiently for his prey to come.

After waiting for a few hours, a shaman finally arrived.

At the moment when he just squatted down and prepared to go to the toilet, Ji Zheng rushed out of the water tank like lightning, and then while covering the other party's mouth with one hand, he cut the other party's neck with a knife, and the action was clean and neat.

After succeeding, Ji Zheng immediately left through the window that had been broken a long time ago. Because of the light and fast movement of his movements, the guards waiting outside the barracks were unaware.

Before the news spread, Ji Zheng immediately rushed to the next camp.

Using the same method, he actually succeeded in killing another shaman, until the news came, and all the demon camps immediately entered the full line of alert.

At this time, Ji Zheng was still in the third camp, and he couldn't leave if he wanted to.

When the demon officer gathered all the soldiers, Ji Zheng knew that something was wrong. His skin looks okay from a distance, but it must be exposed up close. So he hurried away, but was still discovered.

The angry demon officer immediately sent a large number of demon soldiers in pursuit, and also used a domesticated wolf dog to track his scent.

Because he was not familiar with the terrain, Ji Zheng unknowingly escaped to the end of a cliff.

Since there was no way to escape, Ji Zheng could only fight with those demon soldiers who caught up, hoping to fight his way out.

However, after all, the other party was outnumbered, and Ji Zheng couldn't break through with all his might, and he was about to be surrounded and annihilated. With nothing to do, he could only jump off the cliff.

Fortunately, he was killed, and there was a deep river under the cliff, and he was swept away by the river.

Because he was seriously injured, he didn't even have the strength to swim ashore, so he could only hold his breath while moving forward with the current.

As he reached a deep pool beneath a waterfall, he finally had the strength to slowly climb ashore.

After simply bandaging the wound, Ji Zheng began to look at his surroundings, trying to determine where he had been washed away.

Just then, a strong stabbing pain suddenly hit, giving him a splitting headache.

When the headache gradually passed, he suddenly felt an inexplicable familiarity with his surroundings, as if he had been here before.

He was sure he hadn't been here, but how could he explain the feeling of familiarity?

Suddenly, a bold guess arose in his mind.

Maybe it's not that he has been here, but that the big devil Ruan Wuxin has been here before, and those familiar pictures are actually from his memory.

Since Ruan Wuxin had been here before, there must be something here that he cared about very much, otherwise he wouldn't have taken it to heart.

Ji Zheng began to slowly search and search the neighborhood.

Finally, he discovered the mystery of this place: it turned out that there was a very secret cave behind the waterfall.

When I walked into the cave, I saw that there was a lot of space inside, but there was nothing.

At this time, that familiar feeling came again, and this was indeed the place where Ruan Wuxin had been.

Ji Zheng followed the familiar feeling to a mossy cave wall, and then reached out to touch the cave wall.

At the moment when his hand just touched the cave wall, the jade pendant he hung around his neck suddenly floated up in the air and emitted a dazzling red light.

Under this sudden red light, Ji Zheng clearly saw that the cave wall in front of him was transparent, as if it were an illusion.

He took a step forward and stepped in with ease.

He didn't know what was going on, but he instinctively moved on.

At this time, he passed directly through the cave wall like a ghost, and he could even clearly see the rocks and dirt around him.
