The tree spirit did not say his identity, but Kun Yu guessed that the other party should be an abyssal creature, and the time of existence was definitely not short.

Before Kun Yu could continue to speculate, the tree spirit said.

"Now that you're in the prison, let's stay here, I see your strength, the space of this prison should not be able to be broken, besides, even if it is broken, you can't get out. ”

Kun Yu asked suspiciously.

"Don't you want to go out?"

The dryant shook his head.

"Why?"

"Because after so many years, I have made this place my home, and I am really old and I don't want to move my nest anymore. ”

Kun Yu looked at the dirty and gloomy environment around him, and it was hard to believe that any creature would call this place home.

The dryad chuckled.

"I'm talking about home, of course, not here. ”

With a wave of the branches, the surrounding environment changed, and Kun Yu reappeared in the house with a mixture of stone and wood.

The old creature in front of him had already descended to the ground, but it still had no breath of life.

"I'm talking about home, this is it. ”

The dryad waved his hand and gestured to everything around him.

Kun Yu reached out and touched the things around him, the touch was very real, like a real thing, even the tiny details were so real.

Looking at Kun Yu curiously looking around, the tree spirit did not urge him.

Patiently waiting for him to finish his study, the dryad continued to speak.

"This is the spiritual home that I have studied, where you can go about your normal life without feeling like you're in prison. ”

"Here you will gradually forget who you are, integrate with them, and even combine to conceive offspring, and then go through this life happily until the final death comes. ”

Kun Yu looked at him in surprise and asked curiously.

"Can I cultivate here?"

The dryant shook his head.

"There is no energy in the Heavy Prison, so you can't cultivate here, but what's the use of cultivating if you want to cultivate? No matter how high your cultivation is, you still can't get out. ”

"Why?"

"The Heavy Prison is not in the abyss, it is in an independent alternate dimension, and this alternate dimension has been blocked by the royal level with great means, and any creature that wants to forcibly penetrate the spatial barrier will eventually return to the Vault. ”

"Then you're not going to try it again?"

"Do you think I'm the first creature to come in? There were more people before me, stronger than me, older than me, they all tried, but in the end, I was the only one who survived. ”

"They want the so-called freedom so much that they will not hesitate to spend everything, but in exchange for nothing but despair. ”

"Actually, isn't there a bigger cage out there? ”

Looking at this pessimistic tree spirit, Kun Yu no longer said Hu, some creatures, when they decide one thing, it is difficult to change again.

It's not that they don't want to change, it's that they don't dare, they are afraid that these things that they have determined as theorems will one day be shattered, and then their ideas will be shattered with it.

So they are desperate to never change themselves, and they have to drag others not to change.

Compared to persuading the tree spirit, Kun Yu is more interested in this illusion that is almost the same as reality.

Regardless of the dryad's chatter, Kun Yu began to study the illusion carefully.

Perception let go, Kun Yu investigated in detail little by little.

After scanning the entire room for the fourth time, Kun Yu finally noticed that something was wrong.

It's really real here, but it's also a bit deliberate because it's so real.

For example, the stone bed where the tree spirit lies flat, the texture is quite clear, and the texture is very prominent, which fully reflects the reality of the stone.

But there is one problem that is overlooked.

Any stone, in the case of long-term squeezing and friction, the surface will become more or less flat and smooth.

And this stone slab still looks like it has just been cut, and there is no trace of use.

However, removing these flaws, the entire illusion can basically be fake.

No wonder the tree spirits say that you can live here for a lifetime, and as long as you want to escape, this is definitely the perfect paradise.

Seeing that Kun Yu didn't listen to himself, the tree spirit also stopped talking and stopped chattering.

Kun Yu looked at the tree spirit who stopped talking and said in a deep voice.

"It's okay if you want me to live a quiet life in a fantasy, but you'll have to give me the means to build it. ”

The dryad was stunned for a moment, then hesitated.

Kun Yu hugged his arms and was not in a hurry.

After struggling for a long time, the dryad shook his head.

"No, I can't give it to you, this is our last Pure Land in prison, if it is handed over to you, you destroy the Pure Land, and we will not survive. ”

Kun Yu waved his hand.

"It's not about giving me this illusion, it's about creating this illusion, and I don't move your illusion, if you like to play, just play by yourself, how good. ”

The dryad still shook his head, unwilling to say anything.

Kun Yu's eyes changed, staring at the long knife in his hand, and said slowly.

"You see, I'm actually not very weak, at least, I took a look, and there is nothing here that can kill me in seconds. ”

"I'm very resilient, the point is that I'm still very resistant to beatings, you say, what if I destroy it every day in your illusion?"

"You know, this is your last pure land, not for me. ”

After speaking, the energy on his body began to surge up and down, and Kun Yu's eyes became sharp.

The dryad stared at Kun Yu tightly, and the teeth in his mouth gurgled.

After a long time, the dryad gasped and went limp.

Spread out his hands, powerless.

"Yes, I will pass it on to you, but one thing you have to promise, you can't touch my illusion, otherwise even if I fight for this old life, I will want you to be trapped in the illusion forever. ”

Kun Yu raised an eyebrow and agreed.

Soon, a piece of information came into Kun Yu's head.

The method of making the illusion is more complicated than you think.

There's so much knowledge involved.

From the construction of the world to the use of energy, everything must be organically integrated to create an illusion of reality.

One of the most difficult is the simulation of the rules of the world, which involves too much depth.

The rules of the world are the foundation and core of the illusion, whether an illusion is real or not, the biggest criterion for judging is not whether it is like or not, but whether everything done in the illusion is the same as the real feedback of reality.

This is important.

If you stumble and fall off a cliff in a fantasy world, you end up falling in mid-air instead, and you don't even feel like you're falling.

The cliff in front of you is basically impossible to take as real in your perception.

Only there is a real sense of falling and collision, and even all kinds of real changes occur in the body.

This is a real illusion.

And the dryads also mention a point in this, called derivative worlds.

The so-called derivative world refers to the fact that the illusion maker has built a complete framework through the detailed shaping of the rules of the world.

The rest, then, is left entirely to the world to run automatically, and the illusion created in this way is the illusion that he considers to be the highest.

This illusion is more of a real world than an illusion.

That's why he named it Derivative World.

A world derived from a fantasy.
