A month ago, although the immortal medicine obtained in Mt. Iino was passive, it was banned by those onmyoji, and after eating it, it would be activated as soon as it came into contact with the demonic power, so those immortal medicines were useless.

However, the fruit is useless, the tree is still useful, although I don't know what kind of tree it is, but this fruit does have the effect of healing and improving cultivation.

In the past month or so, relying too much on the function of adjusting the speed of time in the small world, he has harvested several batches of fruits, and it is these fruits that have allowed Xiaomeng to break through to a high-level monster.

In the realm before the big monster, it was basically the accumulation of energy, there was no bottleneck, and Xiaomeng was also cultivated in a cramming way.

Now, the fox clan also has a high-level monster, and Taiya can leave with confidence, but before leaving, Tai has to do one last thing.

After driving the others away, Tai took out a fist-sized black bead from his body, which exuded an extremely powerful, scorching aura.

This is a demon core, Zhu Jiuyin's demon core, when he was dealing with the corpse, he dug it out from the dragon's head, at the beginning, Zhu Jiuyin wanted to die with Taitong, it was probably about to blow himself up, but fortunately, he stopped it in time, otherwise he would be seriously injured if he didn't die.

Even if you are lucky and escape to the small world, according to the breath of this demon core, it is estimated that you don't need to help Zhu Jiuyin collect the body, it will definitely be wiped out, and you won't even think about finding the ashes.

For the monster, although this demon core can't help break through the big monster, but eat this thing, it's still possible to enhance the demon power, if it weren't for the elixir, it was originally going to be for the little fox to eat, but now it doesn't need it, it's too much of another use.

Some time ago, Tai got news from Cuizi that about a hundred years later, the aura in this world will become less and less, and finally enter the era of the end of the law, and it will be more and more difficult to practice.

Too much input of demon power into Zhu Jiuyin's demon core, a large amount of spatial attribute demon qi continued to pour in, and the demon power on the demon core was constantly compressed, until he felt too much to reach the limit, and no matter how much he wanted, he would not be able to control it.

Tai began to compile the law inside, and the surface of the demon core gradually formed a thin film, and finally the demon core seemed to be a little uncontrollable, and the demon power suddenly skyrocketed out, and the film was like a balloon, which was quickly blown up, and he hurriedly concentrated his efforts and suppressed it with all his might, and finally it was controlled at a diameter of about one meter.

As the laws of weaving became more and more, the balloon began to evolve into earth, fire, water, and wind, and land appeared below, air appeared above, and water and fire intertwined, clouds appeared, and thunder and lightning collided.

The small world gradually took shape, gradually matured, until it felt too much to open a void crack and cast it into the void.

As soon as he entered the void and broke away from the suppression of Tai, the small world rapidly expanded, and finally turned into a half-plane with a diameter of more than 2,000 meters.

Then, Tai made a door for this half-plane, a door to connect this world, so that this half-plane is equivalent to being attached to this world.

However, although it is attached to this world, the aura of the half-plane is transformed from the void, and it can be self-sufficient, so it will not be affected by this world.

Tai dug a basement in his house and fixed the door in the basement, and this will be the entrance and exit connecting the two worlds in the future.
