National Gardener: I can choose the evolution path of spiritual plants.

Chapter 81 Underground World
Lin Zhi had just taken a few steps forward when he suddenly felt a black screen in front of his eyes.

call!
A gust of wind blew past his ears. Lin Zhi became alert. Without looking back, he raised the sword in his hand and slashed in the direction of the wind, while his body quickly retreated.

boom!
The sound of a heavy object falling reached his ears, and Lin Zhi quickly turned around.

He took out a gem from the warehouse to illuminate the cave, and saw a basin-sized spider on the ground that was cut in half and was oozing green pus and blood.

"It turns out to be a bug from the Green Star Realm."

He looked up and around the cave, and found that there was a cave tunnel connected to this cave. The walls of the cave were full of traces of sharp toes and covered with spider webs.

Lin Zhi moved a large stone from the warehouse to block the entrance of the hole, and then continued to collect the milky crystals.

To collect the milky crystals, you need to gently poke them with a cotton swab, and then use the melted jelly amber to pick them up.

As the earth milk crystals fell into the amber liquid, the amber solidified instantly and then wrapped the earth milk crystals inside.

This way, its volatilization is avoided.

Soon, he finished picking all the earth milk crystals in the cave and obtained several hundred of them.

But this material needs further processing.

So Lin Zhi took out another big pot, cut open the bodies of several wild beasts, took out the heart blood, filtered out the impurities, and poured it into the big pot. Then, according to the steps of the recovery potion, he prepared the ingredients, lit a fire and started to cook.

Finally, after a series of reactions, half a pot of emerald green mucus remained in the pot.

He quickly threw in hundreds of ambers wrapped in earth milk crystals.

As the amber was put in, the emerald green mucus instantly "melted" and turned into a pot full of transparent liquid.

"It's done!"

Lin Zhi took out glass bottles and bottled the liquids. One pot of liquid was filled with 107 bottles of resuscitation potion.

He put away the resuscitation potion, moved the stone that had just blocked the cave back into the warehouse, then threw a fire into the cave and saw the spider web being burned instantly, with thick smoke rising.

He quickly expanded the Source Earth Field and returned to the tree house.

Back in the tree house, Lin Zhi hugged Fu Hua and practiced Yin and Yang for half a day, then fell into a deep sleep.

The next day, thinking that the smoke had dissipated, Lin Zhi walked out of the source earth area.

Then he stepped into the ash-filled cave and after walking about a few hundred meters, he saw a larger cave.

With the light of the gem, he saw hundreds of spider-shaped charcoal in the cave.

After seeing the situation inside the cave clearly, Lin Zhi threw a stone over.

The sound of the stone falling to the ground was clearly audible, but there was no other movement. Lin Zhi immediately felt relieved.

"It seems that all the spiders in this cave were burned to death by my fire!"

He waved his hand to expand the source earth field and merged all the spider chars into the source earth.

These are all good fertilizers for spiritual plants.

Lin Zhi looked around the cave and found that it was extremely large, crisscrossed with many branches dug by spiders.

After exploring dozens of forks in the road, he finally found a different one.

"There is wind in this fork, the air is humid, and there are no traces of coke. This stone wall is formed by natural erosion of groundwater, and there are no traces of excavation, which is obviously different from other forks."

Lin Zhi analyzed in his mind and slowly walked towards the depths of the fork. He found that the mine was slanting upwards.

After an unknown amount of time, he suddenly heard the sound of flowing water.

After walking a few dozen steps, he suddenly discovered that there was an amazing underground world before him!

Lin Zhi opened his eyes wide and saw in front of him a huge, endless cave with a ceiling about a thousand feet high. There were many stalactites hanging down and water dripping.

The surrounding mountain walls are covered with fluorescent moss and fireflies are flying around.

Some mushrooms grow around the ground where stalactites drip stalactites.

Further away, seeing him appear, some rat-like beasts quickly hid behind rocks. An underground river was flowing in the distance. Lin Zhi was sharp-eyed and saw fish swimming in the river.

"Legend has it that there are many worlds with cloud islands in the sky, the Nine Netherworlds underground, and underwater cities under the sea. Each of them is a world in itself. The ancients were not deceiving me." Lin Zhi sighed and walked towards the dark river. When he came to the dark river, he couldn't help but widen his eyes.

The river water was crystal clear, and the bottom was a smooth rocky riverbed. As the water flowed, green crystals were scattered and rolling downstream.

As far as the eye can see, there are tens of thousands of green crystals.

"This this!!!"

Lin Zhi was shocked. He had seen minerals before and had no shortage of them.

However, I have never seen a situation where the river is covered with green crystals and can be picked up at will.

Seeing that the river water was clear and there was no danger, he immediately waved his hand, expanded the Source Earth Field along the riverbed, and collected these countless green crystals.

"This... this is the crystallization of the world tree sap!"

Lin Zhi was horrified.

World Tree Sap Crystals, this is an extremely precious mineral similar to the World Tree Tumor. It is formed by the solidified sap that overflowed when the roots of the World Tree were damaged.

People in ordinary civilizations will not actively damage the World Tree, because this will consume the future of civilization and the potential of the world.

The uses of tree sap crystals in the world are extremely numerous, and Lin Zhi alone knows dozens of them.

For example, using tree sap crystals to refine the potential of spiritual plants, allowing some "waste spiritual plants" that originally had no hope of successfully evolving to embark on an evolutionary path with greater potential.

Or if you are more extravagant, you can directly use tree sap crystals to replace the auxiliary materials needed for the evolution of spiritual plants.

In addition, after using sap crystals, leap evolution will definitely result in positive evolution gains.

"There's something wrong with all this sap crystallized ore!"

The voice of the black turtle sounded in Lin Zhi’s mind.

"What's wrong?"

Lin Zhi hurriedly asked for advice.

"Generally, only space cracks of this level can hurt the World Tree. There are not many situations that can damage the World Tree. Even if the World Tree is damaged, its powerful self-healing ability allows it to heal quickly."

The black tortoise concluded, "There are so many minerals here, the World Tree must be seriously injured! Something is wrong!"

"Maybe it's man-made?" Lin Zhi asked speculatively.

He moved forward along the upstream of the underground river for several days. He saw that the riverbed was crystal clear and the bottom was covered with mirror-smooth rocks. Under the scouring of the water, a piece of green crystal floated downstream.

As he collected large amounts of goods, he went from being excited at first to enjoying it so much, but now he feels numb.

"There are so many crystals here. I estimate there must be hundreds of thousands of them along the way."

I don’t know how much time had passed, but Lin Zhi was surprised to find that there was a "fortress" in this underground world.

The fortress is built of golden rocks, and behind the fortress is a "gray wooden wall" like a barrier.

Purple rhizomes as thick as thighs hung from the wooden walls.

The surface of these purple rhizomes looks like protruding blood vessels, which is hideous and ferocious.

Looking closely, it turns out that their surface is covered with scars, and there is a long and narrow cut at the top, with emerald green juice flowing out.

These flowing green juices dripped into a layer of sand-like fortress, and then a river was seen flowing out of the fortress, with a large amount of crystals flowing along the river.

Lin Zhi was sharp-eyed and noticed that there were four humanoids with dog heads standing guard in front of the fortress gate.

"This is... a kobold?!"

Lin Zhi quickly hid himself to avoid being exposed.

"This is the secondary root of a world tree. There are beings above the Purple Yang Realm inside the fortress." The voice of the black turtle sounded in Lin Zhi's mind.

"The orcs are actually deliberately destroying the roots of the world tree. It seems that they are really as you said, senior. They are completely crazy." Lin Zhi said.
