The extent of this woodland is not very large, only about 100 meters in radius, but it is still very eye-catching in this endless grassland.

The number of trees in the forest is naturally not much, at best only a few hundred. But they are very special, it stands to reason that no matter how tall the trees are, they should have some twists and turns, but the trees are like poles, very straight. And they don't flourish like the trees elsewhere.

The trees are not tall, they are all bare, with only one main trunk and only a few leaves at the top. Another peculiarity is that there are no other plants competing for nutrients except for a large prairie, but these trees are all jet-black, and even the leaves at the top of the trunk are also black.

Only Meng Yu knew that this was not caused by insufficient nutrients or insufficient light, but that this tree was originally like this. It's just that he didn't expect that this kind of thing was not a legend, but really existed.

"What is this?"

The Blood Demon King asked, looking at Meng Yu's surprised look, it was obvious that he recognized these trees and knew where they came from.

Meng Yu approached and touched the trees with his hand, he ignored the Blood Demon King, he still felt unbelievable until this moment, and he was shocked for a long time before explaining to the Blood Demon King.

This tree is called Netherworld Blackwood, and it is mentioned in the Hundred Herbs Collection. However, the description of it is depicted as an anecdote, because it is said that this thing grows in the Netherworld.

Of course, Meng Yu didn't know if hell really existed, but now he seemed to understand a little bit that it was not this kind of thing that grew in hell, but because of the place with Netherworld Black Wood, it became more like hell.

The situation of the Blood Demon and many living beings in the Blood Demon Valley illustrates all this. In order to confirm its characteristics, Meng Yu deliberately approached it. When the chill from the tree's body entered his body, Meng Yu instantly felt as if the spiritual power in his whole body was frozen.

Although Meng Yu's cultivation is very low, he only has a slight touch. However, the yin and yang cyclone in Meng Yu's body quickly spun around, quickly transforming all the spiritual power that was so cold that it was about to solidify to normal.

At this time, Meng Yu was completely sure that this was the source that caused the spiritual power of the entire Blood Demon Valley to become cold, and these Netherworld Black Trees were the culprit. And based on their growth status, Meng Yu deduced that it was around a hundred years, which was also completely mild to the time that the Blood Demon King had said.

Netherworld Black Wood is one of the coldest things in the world, no wonder it can affect spiritual power. And it is said that prolonged contact with this creature can also affect people's personalities.

This may be an exaggeration, but it is also meant to illustrate how cold it is. Just these hundreds of trees infected the spiritual power of the area around it for thousands of miles, which shows that its name as the coldest in the world is well deserved.

"Boom!" The Blood Demon King punched out, directly breaking a Netherworld Black Tree, and the stump flew thousands of miles away. He didn't use any spiritual power with this punch, otherwise he would have directly razed this place to the ground.

"it! It turns out that this is so miserable!" the Blood Demon King was furious, and at this time he finally figured out the reason for his mutation, and hated these strange trees.

Meng Yu shook his hand when he saw it, and said with some pain: "Who let you damage them?" Fortunately, in order to vent his hatred, the Blood Demon King did not use his spiritual power to vent directly with his fists like a mortal, otherwise these Netherworld Black Wood would have been destroyed. Even so, when the punch just now flew away from the Netherworld Black Tree, several of them were hung up.

The Blood Demon King was stunned for a moment, and wondered, "Since these things are so harmful, why don't you destroy them and keep them?"

Meng Yu rolled his eyes, this Blood Demon King was really reckless. Although this Netherworld Wood can bring many adverse effects to nearby creatures, its coldest properties sometimes have unique uses, and this can be regarded as an extremely precious rare treasure in heaven and earth.

"Then you don't have to destroy them, you must know that nothing is defined by absolute pros and cons, if these Netherworld Black Wood are placed in the hands of an alchemist, it will be priceless. ”

Meng Yu was dissatisfied, and complained a little, this Blood Demon King was also too reckless, but fortunately, there were hundreds of Netherworld Black Trees here. Those who know their origin will certainly not complain that this woodland is small, because these black trees are so rare that it is a great miracle that there are hundreds of them.

What Meng Yu said is true, if a variety of pills are added to the Netherworld Black Wood, they can increase the medicinal effect a lot, especially some cultivators who go mad because of the excess of Yang Fire, if they can get the coldest Netherworld Black Wood to neutralize, it will have a miraculous effect.

Not only alchemy, but Netherworld Darkwood also has a lot of temptation for refiners. You must know that if some cold-attribute magic weapons can be tempered with Netherworld Black Wood, the power of the mage will be greatly enhanced.

"It's useful to you, it's useless to me!

The Blood Demon King had only destroyed a few trees he hated, and this kid dared to be dissatisfied. If it weren't for the fact that he still needed Meng Yu to heal his symptoms, the Blood Demon King would have slapped the boy to death a long time ago.

Although Meng Yu said that this Netherworld Black Wood was a treasure to the alchemist, the Blood Demon King did not think that they would be one of the medicinal materials he needed to refine the elixir. Obviously, these things were useless for that elixir, but the Blood Demon King only reminded Meng Yu a few words of dissatisfaction, and did not destroy these black trees again.

"Then what are you going to do with these strange trees?" the Blood Demon King asked, Meng Yu couldn't have cut them all down and take them away, right?

"Naturally, they were charged. Meng Yu smiled, the Blood Demon King didn't know that the real value of these Nether Black Trees was a piece of wood pith in the trunk and a few leaves at the top of the tree.

Meng Yu split a piece of black wood and took out the pith of the wood. It is a palm-sized white solid, very crystal clear.

"Just such a little thing can be tossed like this?" the Blood Demon King looked at with confusion from the sidelines, and sure enough, he found that after Meng Yu took the wood marrow, the cold aura of the entire Netherworld Black Wood had disappeared, which was incredible.

"Huh"

At this moment, a creature like a puppy jumped out of Meng Yu's arms. As soon as the little lion appeared, it hid far away, and it used its spirit to communicate with Meng Yu that it really couldn't stand such an aura.

Meng Yu understood, it seems that the bloodline of this little lion should be biased towards the Zhiyang lineage, and there is a strong rejection of such things. Otherwise, even though this wood pith was released more coldly when it was first taken out, it would not make the little lion have such a reaction.

You must know that this little guy hides on himself but does not come out easily, even when he is dying, it is not exposed in front of people, obviously this time it is really unbearable.

"I noticed that there was a little creature in you, and it turned out to be such a thing. ”

However, the Blood Demon King was not surprised by the appearance of the little lion. Meng Yu didn't know that due to the reason of blood sucking, the Blood Demon King was particularly sensitive to the perception of blood qi, maybe others couldn't find the little lion, but he had already discovered it.

It's just that Meng Yu didn't say it, and he didn't expose it, after all, he didn't want to absorb the flesh and blood of this little guy now.

"Well, but you puppy doesn't seem to be easy. The Blood Demon King sighed, always feeling that this little guy was weird, something extraordinary.

Meng Yu smiled dryly, and said in his heart that you still need to say this, if it weren't extraordinary, how could it be possible to follow my side. However, the little lion does look like a puppy, and the Blood Demon King can directly see that it is not ordinary, and it is also quite discerning.

Meng Yu thought it was funny, because some people said that the little lion was a dog, and this little guy hated others like this the most. Until now, Meng Yu sometimes teased the little lion to make jokes about this, and the little lion still wanted to fight him with his teeth and claws.

As Meng Yu expected, the little lion couldn't speak, and was communicating with Meng Yu with his spirit.

"This old thing, he's a dog! No, it's not as good as a dog, he sucks all kinds of blood, if he can't beat him, Lao Tzu has to fight with him!"

Meng Yu heard a burst of slander, it turned out that this guy didn't dare to provoke powerful people, if Meng Yu said this, he would have broken up with Meng Yu a long time ago.

Looking at the little lion hiding far away, Meng Yu suddenly thought of the woman in the ring. The Ice Illusion Body is the Ice Spirit Xuanhu, she shouldn't be repulsed by this Netherworld Black Wood, right?

It was at this time that a beautiful voice sounded in Meng Yu's consciousness. "Put this stuff in there. ”
