The Legend of the Immortal Cauldron

Matthew patiently studied the functions of each type of tree man carefully.

"All the low-grade spirit stones thrown in before were refined to the twelfth or thirteenth level of Qi Refining Stage. If we throw in some medium-grade spirit stones, will the tree man's cultivation level be improved?"

After testing all the different tree men around him, Matthew looked at the Senluo Ming Tree in the Xumi Small World and whispered to himself.

Now, in the Xumi Small World, there are already thousands of tree men standing next to the Senluo Ming Tree.

And the Senluo Ming Tree has stopped growing, and no leaves fall from it.

This is because all the spirit stones Matthew put in have been absorbed.

Without the supply of energy, the Senluo Ming Tree will stop growing.

This made Matthew feel relieved.

At least, the Senluo Ming Tree will not grow endlessly, so it will not destroy the Xumi Small World.

After thinking for a while, Matthew took out some medium-grade spirit stones and threw them into the Xumi Small World.

After the spirit stone entered, the Senluo Ming Tree reacted again.

This time the reaction was not strong, because the number of spirit stones Matthew invested was not large.

Soon, leaves began to fall from the Senluo Ming Tree again.

However, when the leaves fell this time, two leaves actually merged with each other.

Then, a somewhat different tree man appeared.

Matthew moved his fingers and immediately took out the tree man.

This tree man's body was a little thicker than the ones at the beginning.

This tree man's belly was bulging, like a fat man.

After Matthew passed a ray of spiritual light into the tree man's body, the tree man's body immediately began to swell.

Seeing this, Matthew's face changed slightly, and he immediately released a light shield to protect himself.

Then, a huge explosion sounded.

The whole cave shook violently for a few times because of the explosion.

After the power of the explosion ended, Matthew removed the shield.

At this moment, the cave was in a mess, and the previous tree men had all been destroyed in the explosion.

Matthew did not feel heartbroken, but showed a hint of excitement.

"The power of the explosion just now is equivalent to the full force of a cultivator who has reached the Great Perfection of Foundation Establishment. That's right, the quality of the spirit stone can indeed affect the cultivation of the tree man!" Matthew took a deep breath and said.

Then, he took out several tree men in the Foundation Establishment period from the Xumi Small World.

This time, Matthew found that no matter what kind of spirit stone was put in, the refined tree men were all in the Foundation Establishment period, but they all had only one function, that is, self-destruction.

After some calculations, Matthew also knew it.

Fifty pieces of low-grade spirit stones can refine a tree man in the Qi Refining period.

Similarly, thirty pieces of medium-grade spirit stones can refine a tree man in the Foundation Establishment period that will self-destruct.

Next, he will see how many high-grade spirit stones can refine a tree man in the Core Formation period.

This time, Matthew put the high-grade spirit stones in one by one.

When he threw twenty pieces, three leaves fell from the top of the Senluo Ming Tree.

Then, the three leaves merged together and turned into a new tree man.

Matthew moved his fingers and immediately took out the tree man.

The tree men in front were a bit rough, but this one was much more refined.

The outline of the facial features was also much clearer, and the body of this tree man was just a little bigger than that of a normal person.

There was also a wooden long sword on his back.

"This shouldn't be a self-destructing tree man."

Matthew whispered to himself, and flicked his finger, and a ray of spiritual light hit the body of the sword-carrying tree man.

Suddenly, the sword-carrying tree man's eyes lit up, and the wooden sword behind him flew out and fell into his hands.

Then, the tree man began to swing the sword.

Every time he swung, a stream of sword energy would shoot out.

Cut grooves on the inner wall of the cave.

"The power is not bad, it is indeed at the level of the Jindan period, but it is only at the early and middle stages of the Jindan period." Matthew said to himself after checking for a while.

Even so, the strength of this sword-carrying tree man is higher than that of some monsters.

Matthew was quite satisfied with this.

"According to the conclusions reached so far, the best spirit stone should be able to refine a tree man in the Nascent Soul stage. It's a pity that the best spirit stone has long been extinct in the human world, and I'm afraid it doesn't exist anymore."

Since he entered the world of immortal cultivation, he has only heard rumors about the best spirit stone, but has never seen it.

Matthew has always believed that the best spirit stone only exists in legends.

This attempt is truly completed.

Now, as long as there are enough spirit stones, Matthew can also have his own army of tree men.

However, the number of tree man army can't be compared with the army of demons.

After collecting the tree men around him, Matthew left the cave.

After he came outside, he began to look for monsters.

Spirit stones can refine tree men, and he wants to try whether monsters can also refine tree men.

Spirit stones are limited after all. If monsters can, then he doesn't need to worry about materials at all.

There were no monsters around him.

Whenever a monster appeared, it would be immediately destroyed by the bounty teams.

Therefore, Matthew also ran to a farther place to look for monsters.

When he came to a vast area, there were a lot of monsters living there.

Matthew did not hide his whereabouts. He started to capture monsters as soon as he appeared.

Most of the monsters here are of the lowest price, and they have no resistance to Matthew.

In a very short time, Matthew's spirit beast bag was full.

In the end, Matthew took out the Xumi small world and performed the soul fusion technique on it. Matthew took the Xumi small world and threw the captured monsters directly into it.

While Matthew was capturing, he was still observing the situation inside.

After the monsters were refined, the black powder they turned into also fell into the pit.

And the Senluo Ming Tree inside also immediately absorbed the powder.

However, no leaves fell immediately.

Instead, some black dots began to appear on those leaves.

As Matthew threw more and more monsters in.

Some black dots on the leaves began to fall after reaching a certain number.

When the leaves fell to the ground, a monster with a strange body appeared.

Matthew also immediately summoned the monster out.

The monster looked like a crocodile, with a body length of 70 to 80 meters, and its tail alone was 30 meters long and extremely thick.

It also had a bloody mouth.

There were many black spots on its dark green skin.

After the monster appeared, Matthew did not need to transfer spiritual light into its body.

The crocodile-like monster rushed directly towards some monsters.

With its big mouth, a monster was directly bitten to pieces.

It swallowed it into its stomach in a few bites.

With a strong sweep of its thick tail, several monsters were beaten to death.

"It's so ferocious, so let's call it a fierce crocodile." Matthew said with a chuckle as he looked at the crocodile monster that was still fighting in the group of monsters.
