The Legend of the Immortal Cauldron

Under Matthew's gaze, the body of the bison monster in front of him began to expand rapidly.

With the injection of Xumi Yuanling, its body seemed to be awakened, full of vitality and strength.

In just a few breaths, the body of the bison monster had expanded more than twice as much as before, and its thick muscles shone in the light, like a towering mountain.

However, the shape of the bison monster did not change at all, and it still looked rough and wild.

The enlarged bison monster made a heavy breathing sound, but the look in its eyes when it looked at Matthew was extremely gentle, without any tyranny.

After a few more breaths, the size of the monster swelled again.

Its body was like a huge black hill in the center of the cave, heavy and stable.

Fortunately, this cave was large enough to support such a large monster, and the surrounding rock walls seemed to be silently supporting it all.

Looking at the monster that was still growing a little bit, Matthew's breathing became a little hurried, and an indescribable excitement surged in his heart.

Suddenly, Matthew made a hand gesture.

The huge bison monster in front of him shrank rapidly like a deflated ball.

In the blink of an eye, it returned to its original appearance.

At this moment, the magic spell in Matthew's hand was also completed.

Suddenly, the magic-forbidden rune appeared in front of him.

Matthew stretched out his hand, pointed at the magic-forbidden rune, and silently chanted a spell in his heart.

Suddenly, a ray of black light floated out from the rune and slowly floated towards the bison monster.

At the same time, Matthew turned his wrist, and an exquisite jade bottle appeared in his hand.

He opened the bottle cap and hooked his finger, and fine black powder floated out like a meteor shower.

These powders were the remnants left after the Xumi Small World refined those monsters, containing invisible power and mysterious energy.

With the guidance of Matthew's magic power, the black powder began to fly towards the bison monster in front.

Matthew felt a little bit of anticipation in his heart.

When the black powder and the black light entered the body of the bison monster together, Matthew felt nervous.

He held his breath and focused, staring at everything in front of him.

At this moment, the body of the bison monster did not expand again. Instead, at this moment, a faint black halo appeared on the surface. The halo was like the mist in the morning light, soft and mysterious.

About a cup of tea later, the bison monster was completely wrapped in the black halo.

It was hard to see what was going on inside.

However, the black halo now seemed to be breathing, expanding and contracting slightly.

The jade bottle had been put away by Matthew, and the magic-forbidden rune was still continuously releasing black light.

At this moment, Matthew's hand gesture changed, and the magic-forbidden rune immediately floated towards the black halo in front.

After Matthew pinched the hand gesture again, the Xumi Small World also appeared beside him.

When the Xumi Small World appeared, the magic-forbidden rune had already absorbed the halo.

Under Matthew's control, the magic-forbidden rune also flew back immediately.

Then, the magic-forbidden rune immediately flew into the Xumi Small World.

After the rune entered, it immediately turned into a very small one.

After floating in the Xumi Small World for a while, it fell into a small pit.

This pit was dug by Matthew before, just for now.

After the magic-forbidden rune fell into it, the halo also flew out of the rune.

As Matthew moved his fingers, the magic-forbidden rune also flew out of the Xumi Small World.

When he put the rune away, he also breathed a sigh of relief.

"At present, this demon seed has been planted. Next, let's see if I can cultivate my own demon." Matthew said to himself with a look of expectation on his face.

This so-called demon seed is the method he thought of in imitation of the demon seed of the Black Evil Sect.

However, his demon seed is not the same.

He wants to use the Xumi Small World to cultivate his own demon.

The inspiration also came from the words of the ghost baby saying that he wanted Yue Ru to help cultivate the ghost clan.

He has asked the ghost baby for the secret method of cultivating the ghost clan, and has also learned it in depth.

The method of the ghost tribe is to use special materials to cultivate the tribe members, and the materials he used are those monsters.

He had failed hundreds of times before.

He also caught all kinds of monsters for experiments, and even caught several Yuanying monsters.

Fortunately, monsters are everywhere, so he doesn't have to worry about the situation of monsters even if he wants to make more attempts.

After so many failures, only this bison monster can withstand it.

Now, all the preliminary things have been completed.

The next step is to put more monsters in it to nourish the monster seeds.

For this reason, Matthew also prepared several spirit beast bags early.

They were all filled with monsters.

After taking out a storage bag and throwing monsters into it, Matthew looked at the situation inside.

Under Matthew's guidance, the black powder refined by Xumi Yuanling also gathered towards the small pit.

The powder fell and was immediately absorbed by the black halo.

Matthew continued to take out another spirit beast bag and poured all the monsters in it into it.

In the following time, he kept repeating this.

He stopped only after all the monsters in his hand were used up.

"Success or failure depends on now."

Matthew took a deep breath and took out a gray crystal the size of an egg from his arms.

After taking a look at the gray crystal in his hand, Matthew threw it into the Xumi small world.

Matthew shamelessly asked Yueru for this gray crystal.

This crystal is called Nine Yin Yuan Crystal, which can only be refined by people with Nine Yin bodies.

It is an extremely rare Yin thing in the world.

Even Yueru can only condense such a piece in a hundred years.

That is to say, Yueru does not care about him. If it were someone else with Nine Yin bodies.

Even if Matthew gave more rewards, he would probably not agree to this.

After all, it would take at least a hundred years to condense a Nine Yin Yuan Crystal again.

Yueru was able to take out this thing because there was already a Nine Yin Yuan Crystal in the flesh body. Otherwise, even if Matthew wanted it, Yueru could not take it out.

Matthew wanted to use the Nine Yin Yuan Crystal to let the demon species complete the last step.

However, he was not sure.

All of this is just my guess. It doesn't matter that I failed so many times before.

But there is only one Nine Yin Yuan Crystal. If I fail this time, I'm afraid I won't have the chance to try again.

Therefore, after throwing the Nine Yin Yuan Crystal in, Matthew began to get a little nervous.

He focused on everything in the Xumi Small World.

When the Nine Yin Yuan Crystal fell steadily on the black halo without any accident under his control, Matthew's hanging heart was slightly relieved.

At least, this first step was successfully completed.
