Lin Yu didn't know much about the black rain, the rain in the abandoned city was transparent and colorless, although it was an abandoned city, it was much safer than the current greedy domain.

The black shadow laughed in his mind: "Boy, this is a good opportunity, the black rain here is just right to replenish the missing aether element in your body.

“？”

"Aether is the element corresponding to the earth attribute"

The dark shadow explained wordlessly.

"Really?"

Lin Yu's mouth didn't move, he turned around and pretended to search in the direction of no one, and asked the black shadow in his mind

"Of course, this is what the old man found when he was looking for the entire Huaxia Continent."

Lin Yu was half incredulous, and as soon as his mind moved, a small stream of mental power poured out of his palm, quietly wrapping the black rain that fell in his hand.

Absorbs the black elements in the black rain into the body at a very fast speed.

For a moment, Lin Yu felt that his body was in pain as if it had been stung by countless wasps.

In the originally gray meridians, a faint black air flow surged up at this time.

The pain disappeared in less than a second, leaving only the black element in the meridians.

"Boy, this is a secret that the old man spent more than ten years to discover, you kid don't miss this opportunity, you already have four elements in your body, just this fifth, as long as the five elements are gathered, your cultivation will definitely become the second person in time."

"Second in the World"

Lin Yu repeated to the black shadow and asked, "Why is it the second, not the first?"

"Because the first is me."

After the shadow finished speaking, he laughed insolently

Lin Yu has a black line, this uncle is really a weird person.

But what he said just now was indeed very right, the black qi in his body did not have the slightest backlash, but was a little docile, and gradually merged into the inner wall of the meridians.

"Lin Xuan, gone"

Zhao Xiang shouted coldly at Lin Yu.

Lin Yu hurriedly turned around and followed them on.

Although Zhou Jingnan was looking for it, he didn't want to miss this great opportunity to absorb the ether element.

The black rain might stop at any moment, if only we could find a way to collect it.

Lin Yu thought quickly in his heart, do you want to take a kettle and put some black rain?

No, the kettle is full of water now, and I have to keep it for drinking, and it would be a waste to pour it out.

There are parasites or heartworms in the water in this greedy realm, and this risk cannot be taken at all.

But if this black rain is not collected, it will not be able to absorb much if it is absorbed secretly.

Lin Yu felt a little sorry in his heart.

After searching in the woods all day, the five of them did not find Zhou Jingnan, and Old Man Wu's face became more and more ugly.

When evening came, the black rain did not stop, and Lin Yu and a few people walked in the muddy woods for a day, and they were already exhausted by this time.

For Zhou Jingnan, an ominous omen rose in everyone's heart.

It is estimated that something has happened to him, which is the worst outcome that everyone can think of.

But whether it's life or death, at least find him.

Because of the rain, the five of them did not replenish their food all day, and they were all a little exhausted at this time.

The night in the woods was extremely cold, and the clothes on their bodies were already soaked, and everyone lost the impatience of the early morning.

"Let's find a place to rest for the night"

Old man Wu said helplessly, and led everyone along the southeast of the woods.

The black rain continued to fall, and Old Man Wu led everyone to a hill and found a low cave.

"That's it"

Old man Wu pointed to the cave, and a ball of fire emitted between his fingers, shining towards the cave.

The hole is shallow, and the rock wall is full of scratches, as if it was deliberately dug out by some animal. The space is almost just enough to accommodate five people.

The side of the cave was littered with animal droppings, and Lin Yu couldn't tell what animal was here before.

At this time, he didn't have the heart to pay attention to that kind of thing, so he followed Old Man Wu, curled up, and got in.

As soon as the five of them got inside, the entire space was filled.

The bags were piled aside, and the five of them were silently eating dry food, looking at the black rain falling quietly in front of them, and their feelings were extremely complicated.

Lin Yu thought that Zhou Jingnan had better be like them, hiding somewhere in the Greedy Domain, waiting for them to find him.

But on the other hand, he wondered how he could collect the black rain.

Biting the dry food and chewing it in his mouth with difficulty, his cheeks hurt a little, but he didn't drink water in a hurry, there were only two pots of water, which could barely be enough for a week, but now Zhou Jingnan's disappearance has stretched the time by I don't know how many times.

The water needs to be spared to drink, as for the collection of black rain is a bit tricky, if the rain stops tomorrow morning, it will be difficult to wait until the second one, maybe the second black rain has not fallen, they have already returned to the academy.

After eating the dry food, Lin Xuan offered to keep vigil tonight.

Bent over and walked out, making room for the four of them to rest.

Old man Wu stopped him sharply.

"You rest, I'll keep vigil, I don't want to get lost again"

Lin Yu stopped him.

"Teacher, I can do it, you forgot, I'm from the ruined city"

Lin Yu said a word, and everyone was silent.

Old man Wu looked at Lin Yu, and there was some worry in his eyes.

"Teacher, I'm nearby, I won't go far, I'm good at vigil, you better stay here and take care of them"

After Lin Yu finished speaking, he turned around and left the entrance of the cave, and walked towards the side of the cave with a dagger.

The black rain fell on him, and he was excited at the moment, this was a great opportunity. It must not be wasted.

Looking up at the dark night sky, the black rain was falling head-on. Lin Yu spread his hands wide, enjoying the surprise brought by the black rain.

I found a place not far from the entrance of the cave, and sat cross-legged on a smooth stone under the shade of a tree branch.

The heart was silent, and he used his mental power to wrap up the black rain that fell around him, constantly absorbing the etheric elements inside.

The thunder rumbled, the black rain fell violently, and Lin Yu sucked it beautifully, although there would be pain, but it was worth it.

The five elements of chanting focus on the balance of the five elements, and now he is the only one who lacks this ether in his body, and now the supplement of the ether makes the meridians around his body begin to exude a strange look.

There was a steady stream of thin black aether pouring into the gray-white meridians.

Before practicing, Lin Xuan opened the iron box he was carrying and placed it in the depression on the side.

The black rain fell on the ground and was absorbed by the tin box in the middle of the depression.

Although there was a phoenix egg inside, it did not leak the slightest breath in the black shadow's telekinetic wrapping.

In addition, there are thousands of spirit stones stacked on it, so there is no need to worry that Old Man Wu will find out.

The black rain took advantage of the moonlight to fall more and more violently, and the water droplets crackled on the leaves.
