The skin is the phloem.

As long as you are not destroyed, you can live well if you hollow out the heart of the tree.

The temple hollows out the tree heart, which actually has several functions.

First, it is convenient for God to take care of the tree of life.

Robin hasn't figured out what the principle is, so it can only be explained as a special magic.

God's messenger comes to the tree heart every day and can do two things-

Inside the tree center, a circular ditch was dug in the part close to the tree wall.

Robin didn't quite understand whether it was dug by hand or formed naturally, but the ditch was filled with black sediment.

They come from the tree walls, as if they are human sweat, and will penetrate from it and gather here.

The sediment starts flowing and gradually gathers into the circular groove in the center.

Then it gradually condenses and becomes a slightly hard object with glue.

The black sediments emit an indescribable odor.

But the messenger of God told Robin that you cannot simply dispose of these things as tree feces.

Instead, Carista said, these things are more like the blood of the main tree.

After breathing, a blood that brings out countless pollutants after it provides nutrients to its body organs.

Are the pollutants dirty?

Of course dirty.

If you let it go and let them accumulate, the main tree will get sick.

Become wilted, or even die.

But, if you drain the blood.

Then the main tree of life will wither quickly in a short period of time.

There has been such a tragedy in history—

For a time, Lopez had an idea called "Laws" that a part of it was a real and objective law. The great wise man Ruth Valen was the drafter of the Laws.

This was originally a subtle branch in the realm of magic, but Ruth discovered some interesting phenomena:

When magical alchemy, some hot air spurted out at high speed is inevitably generated.

These heat is sometimes extremely terrifying. It will cause the metal alchemy furnace to explode and can also lift the heavy lid.

But these heat does not come from magic.

When using fire magic, Ruth discovered that whether you want it or not, it always seems to be accompanied by wind, even if you have never called wind magic.

Similar things will happen when using wind magic, such as somewhere will become more hot.

So Ruth also wrote another book called [Compound Magic] and [Symbiosis and Transformation of Magic].

When Robin saw these in the book, he couldn't help laughing.

This is simply the foundation of natural science.

And that person named Ruth Valen is simply Newton from the Normeer world.

Therefore, after so much correct research, Ruth inevitably applied her laws to plants, and later a book [Plant Life Law] was born.

One of the points is mentioned, which mentions the previous composition of xylem and phloem.

After the rules were verified countless times, Ruth's courage also became stronger.

So she turned her eyes to the tree of life, which is also a plant. Although Ruth's starting point was good, she believed that the black liquid discharged by the tree of life was a substance that was harmful to it. (The Gods and believers all scoffed at this, because this is a well-known fact.)

But no one dares to verify what will happen after the black liquid is discharged.

Ruth Valen took an extremely important step.

And this step was enough to erase the achievements of her first half of her life and be permanently nailed to the wall of shame.

Lopez's main tree of life began to develop lesions after the black liquid was removed one week after it was removed.

There was only a little sign at the beginning of the period, and some white spots appeared on the outer skin of the main tree.

Then these spots expanded rapidly, and the subtrees of each territory died one after another during this period.

Finally, when the main tree turns yellow, leaves wither and dying.

People stopped Ruth's crazy behavior.

God and his followers grabbed her, nailed her hands and feet to the wall of shame with nails, and then, under the spitting and beating of the crowd, the most famous wise man in history, Robin believed that Normel Newton, died because of blood, starvation and disease, because of his sunlight, he survived for thirteen days.

If you want to say what Ruth has dedicated to mankind in the end, then there are only two points-

1. The black liquid flowing in the main tree of life cannot be eliminated casually.

2. Any act of blaspheming the tree of life is foolish and contrary to God's will.

So Ruth was nailed to the wall of shame. Until today, if Robin could go to the capital of Lopez to watch, he would find that there was still a statue of Ruth being nailed on the wall of shame in the Central Square.

The land below the statue is forever filled with the smell of rotten food.

That is the dissatisfaction of the people with spit and rotten food for their blasphemy.

Then, Ruth's death caused the efforts she had made before was wasted, and did the subsequent [Laws] not develop any further?

No.

Not so.

When Robin turned his back on history, he felt extremely relieved, and it was natural.

The fire of knowledge and wisdom will not be extinguished once it is ignited.

However, her regular science has later been integrated into part of magic, and based on the [compound magic] and [symbiosis and transformation of magic] she proposed, the scope of magic has been expanded a lot.

These also promoted the formation and development of modern magic.

"Robin, come."

Carista's voice brought him back to his senses from the thoughts of history.

Robin nodded and walked towards Carlista.

In front of them was the tall groove, which contained black glue liquid.

The edge of this groove is inlaid with a golden metal edge, and the edge is faintly filled with blue magic.

This magic is used for early warning.

If the discharge of black liquid has exceeded the upper limit of the groove, it will make the alarm bell in the room make a harsh sound.

Of course this situation is very rare.

Unless it is during the period when God is sick, or at the end of life.

Because of lack of timely care, accumulation will occur.

Carista leaned forward expressionlessly, then completely immersed her slender and fair arms into the black liquid.

Robin's brow frowned slightly.

He saw a layer of fine beads of sweat quickly emerged from the forehead of the messenger.

A white light overflowed from her body, gathered into her hands, and merged into the black liquid.

In a short while, a low roar from the black liquid could be heard.

As if boiling, bubbles gushed out.

Then it broke and made a gurgling sound.

This process didn't last long, and about five minutes, the layer of black faded a lot.

The messenger of God and the chosen one are the only ones who can purify the blood of the Lord Tree.

This is also why every country needs them.

But according to Robin's observation of Carista during this period, the God Messenger and the Selected One have more than just the ability to [purify].

Purification will not allow flowers to bloom.

...

Carista pulled her hands back and looked at Robin panting.

The latter quickly took a step forward and gently wiped the sweat from her face.

"Okay," Carista's lips were pale and her chest kept undulating. She smiled sweetly and looked at Robin with a high hopes, "You try it."

Robin didn't say anything, just nodded and squatted beside the groove.

Learn [Purification].

This is one of his compulsory courses every day.
