The Knicks were a little far away from Harry, and they didn't hear Harry's conversation with Rita Skeeter.

He was thinking about Hagrid's good fortune. Although he didn't see Hagrid in Hogsmeade, he wasn't so disappointed, at least knowing that Barty Crouch was suspected of dying.

Tifa and Luna, who were next to her, were also very satisfied, and both of them had paid for their shopping today. Nicks eventually gave up on the idea of going to the Forbidden Forest, and before leaving Hogsmeade, he went to the post office to send an order to the potion shop in Diagon Alley.

Back at Gryffindor in the evening, the Knicks noticed that the trio's expressions had become cheerful and no longer worried.

On Sunday, the Knicks took Luna for a walk by the Black Lagoon. In January, the Black Lake partially thawed, and many students walked along the shore.

The Knicks see their sisters Tifa and Neville crouching on the shore and don't know what to do. In the distance, Victor Krum was exercising in a thin fabric by the lake, and after warming up, he plunged into the black lake and disappeared.

Approaching Neville, the Nyx sees him throwing a ball of seaweed into the lake. It didn't take long for this clump of seaweed-like thing to split into two, three, and several clumps.

Neville picked up one of the lessons and shook his head, and the rest quickly withered, only the lump in Neville's hand was still alive, and he threw it down again, and the split began again.

Upon approaching, Luna asked, "What are you doing?" ”

"Grass, gill sac grass." Tifa replied.

"What's that?" Luna asked curiously. Neville looked up, "A plant that helps people breathe in the water, I discovered it in Professor Moody's book "The Amazing Aquatic Plants of the Mediterranean." Nicks wondered, "One is enough, what do you want to do so much?" ”

"I want it to mutate, you know, I can make it change when I plant grass, I want it to help me breathe underwater and help me find things." The Knicks turned to Tifa.

Tifa was uncomfortable with him, and said, "What to see, I didn't suggest it, he came up with it himself." This time it was the Knicks' turn to be surprised.

Neville has always come across as stupid, and it's surprising to think of mutating the gill sac grass. But Neville's positive response to the game shows that his mood has changed, and his inner courage has been inspired.

Neville seemed to explain, as if he was talking to himself, "This is useless, it's just a permanent access to gills, what I need is to be able to keep warm, find items, and preferably have some mutation in combat ability." When the Knicks heard this, they felt that Neville was too demanding and asked, "Neville, do you have any results?" ”

"There are some, and there is one that allows you to breathe underwater and find things."

"How do you know you're looking for something, have you already eaten it?" Luna asked.

"I don't know how to describe it, but I know what they do when I hold them." Na'vi Road.

Nicks looked at the gill sac grass in Neville's hand and fell into thought, is this also a seed? Neville could tell what it was doing when he held it in his hand.

Neville threw the gill sac grass into the water again. A few more clumps of gill sacs slowly grew in the water. Tifa took out a clump of gill sac grass from the lady's backpack and showed it to Luna, and whispered, "This is it, it can make people breathe underwater and find things." Luna watched carefully for a moment.

"It's no different from those ordinary gill sac grass!"

"yes, I can't see the difference, but Neville says the grass can find things." The Knicks also glanced at it and believed Neville's words, who rarely lied.

And Nicks thinks that it is normal for gill sacs to appear to find things, in his cognition, there are many ways to find things in the water, in addition, the perception of plants is very fascinating, there will always be unexpected methods, especially a magic plant in the wizarding world.

Nix thought for a moment and persuaded, "Neville, it's okay to be able to find something in the water, you don't need to have everything." Neville nodded, "I know, Tifa said so, but there is only one such gill sac grass, and I don't have one after using Harry and Seamus, and I want to plant two more." "The Knicks were tempted to convince Neville to leave those two alone.

Give them plain gill sac grass on it. But he didn't do it. For Neville, this is the first time he's been able to help, and it means a lot to him.

For Nix, if he asks Neville for some herb materials in the future, he will not be able to cope with the cost.

It wasn't long before another mutated gill sac grass appeared, and Neville picked it up and shook his head.

Nor was it the mutation he wanted. Nicks asked, "What effect?" Neville was stunned for a moment, then replied, "It attracts something and covers it." ”

"Attraction what?"

"Something very small, it's food for it." The Knicks understood that it attracted microbes and didn't mean much to the game.

If it is lurking in the water, it is very useful, attracting microorganisms to wrap the whole body, a good camouflage. He took the gill sac grass.

"I want it, it's an interesting effect." Tifa was curious: "Brother, do you want to refine it into a potion?" ”

"Maybe." Nix replied. Neville continued to plant grass, and it wasn't long before another mutated gill sac grass was fished out.

Nicks wondered, "Neville, you have a good chance of mutating them today?" ”

"I've got a little bit of a knack. Also, they are different from trees and flowers, they reproduce faster and have less magic power. "Neville Road.

Nix suddenly thought of a question, whether mushrooms are animals or plants, remember that they belong to the fungus class. Can Neville ripen?

If you could, the mutated mushroom would work well.

"Neville, can you ripen mushrooms?"

"Yes." Neville stopped talking.

"What's the problem?" Nicks asked.

"Mushrooms need a lot of fertilizer, but once the fertilizer is not enough, they will not grow, and although they reproduce quickly and have a high probability of mutation, they are not very good."

"What's the wrong way?"

"Most of them are poisonous, and a few can make people very powerful, but after they are powerful, they will become stupid." Nicks frowned, it shouldn't be like this, isn't the mutation random?

Actually, this was Neville's problem, and he often heard stories about poisonous mushrooms as a child. When you grow up, you subconsciously think that there is something wrong with mushrooms, so mushroom mutations will be biased towards poison.

As Ne'vi's herbalism deepened, the mutated species he grew were also affected, and in the end, they would be completely controlled by him, and the direction of the mutation would greatly meet his expectations.

By the evening, Neville had gotten four gill sacs that could be found underwater, and they might have found things in different ways, but they all met expectations.

The best of them also has the added ability to keep warm in water. There were more mutant gill sacs that didn't meet Neville's expectations, all taken by the Knicks.

You are a genius, remember in a second: Red Sweet Spring:
