On the way back, the undocumented knight also mentions the kelp monster that he solved not long ago with Saitama.

"So, it's a weirdo with a kelp on his head?"

"It's not counted, although it is very similar to kelp, but it is very hard, even more than ordinary steel, and it can be freely expanded, and the strength should not be underestimated, these performances really don't look like kelp, but whether it is kelp or not, we have to wait until the results of the research come out to make a conclusion."

"But it's possible that it's really a special kind of kelp, right?"

"You can think of it that way, but I think it's more likely that it's just more like."

Speaking of which, seeing Saitama sitting in the back seat without a license through the rearview mirror was thoughtfully without saying a word, a little strange, why did this guy get distracted when he said it?

At this time, Saitama was still thinking about the kelp monster in his heart.

First of all, Saitama felt envious and even jealous from the bottom of his heart that the kelp monster could have hair that could be up to nearly 100 meters long, he didn't like to have long hair before, but if he was allowed to go back to three years ago, he would definitely never cut his hair again.

Secondly, Saitama remembered that he had mentioned that kelp could grow hair in one of the hair growth tips he had looked up on the Internet before.

At first, Saitama was full of hope and ate kelp for more than a month, and even had the behavior of eating it raw without adding any seasoning in order to get all the nutrients of kelp.

Unfortunately, more than a month of hard work had no effect at all, and his head continued to fall off rapidly until it could no longer be dropped.

At this time, the appearance of this kelp monster suddenly reminded Saitama of this incident, and he had thought about whether it was not good for which kelp varieties he ate, and he immediately thought about whether the other party's hair that was suspected of being kelp could help him grow hair.

"Why don't you go back and get some from the institute now?"

Immediately after, Saitama shook his head.

"Forget it, wait until the research institute confirms that it is indeed kelp, and then tell Mr. Yue, he should be able to confirm whether that thing has an effect on me......

Thinking of this, Saitama suddenly laughed, but he fantasized about the day when he regained his thick black hair.

"Huh? What are you laughing at? ”

"Nothing."

"Speaking of which, Genos-kun really worships you as a teacher?"

"Uh...... Sort of. ”

"Don't teach him badly!"

“……”

In this regard, Saitama is speechless, what can he say? He really doesn't want to be this teacher, okay, he often has a headache because of how to teach a blonde cold-faced man, even if he really teaches badly, it definitely has nothing to do with him, it's all self-taught by that guy and that guy......

“……”

“……”

The two chatted while rushing back to Z City.

……

Half a month later, Saitama and Unlicensed were notified by Zhang Yue to come to his research institute.

Saitama, who felt very comfortable riding the Knight No. 1, refused Genos's offer to fly him directly after learning on the phone that he was going to go without a license, and planned to leave with him.

In half a day, the two had already traveled through four cities and came to Zhang Yue's research institute again.

For this institute, both of them have been to this institute many times, and the road is still relatively familiar, and they don't need to be led, and after a staff member told them which room they were going to, they found a place by themselves.

After waiting for less than ten minutes in this room, which was obviously a laboratory, Zhang Yue walked in.

"Teacher!"

"Mr. Yue, is there any good news, is there any progress in research?"

"Hehe, good afternoon, I've been waiting for a long time."

Seeing the respectful disciple and Saitama with eagerness and expectation, Zhang Yue greeted unhurriedly.

But then without waiting for the two to reply, Zhang Yue pointed to the two experimental cabins behind the two of them, and said seriously: "My experiment is just at a critical time, I need the two of you to cooperate, it's not dangerous, but it may be a little painful, if you agree, you can go in there for a while, about half an hour." ”

Hearing Zhang Yue's words, the unlicensed teacher who trusted his teacher incomparably turned around and entered the experimental cabin without saying a word.

As for Saitama, he looked at the experimental cabin with some suspicion and asked uncertainly, "Does that thing have an effect on treating my hair loss?" ”

"No, this time it's another experiment that requires you to cooperate with me, and it has nothing to do with your hair."

Zhang Yue denied it very simply.

Although he did not fool the bald man in front of him, he would not really take the other party as a fool, let alone show himself to be absolutely great and selfless, so he would not hide his intention to study his magical and terrifying powerful body.

However, it is precisely because of Zhang Yue's frank attitude that Saitama trusts him even more.

"Well, I'd better think about it."

After hesitating for a moment, Saitama planned to ask Zhang Yue if there was any progress in the treatment of his hair, and it was best to use the research value of his body that he couldn't understand to urge the other party.

Although he is a scumbag, he just lacks a tendon for cultural learning, which does not mean that his IQ is low.

He still understands such a thing as using his own value to seek his own benefit.

"See what this is?"

Zhang Yue was also prepared for Saitama's reaction, and casually picked up a test tube from a table next to him, which contained some green solution with some bubbles.

"Huh?"

"This is something that was extracted and synthesized from the hair of that 'infinite kelp' without a license not long ago, although there is no scientific basis for kelp hair growth, but this weird man's hair is really unexpectedly very effective."

Looking at the test tube in Zhang Yue's hand, Saitama's eyes became brighter and brighter, and he eagerly asked, "The effect is very good?" How good is it? ”

"Of the 482 volunteers with severe hair loss, more than 100 of them were completely naked like you, 480 of them recovered completely, and the other two also played a role, with a 100 percent chance of being effective...... Of course, there is only hope that it will help you, after all, you know your own peculiarity. ”

"It works so well!"

With an exclamation, Saitama didn't need Zhang Yue to say anything more, turned around and rushed into the experimental cabin.

"Let's get started!"

After entering, he glanced at the test tube in Zhang Yue's hand with a fiery eagerness, and then this guy couldn't wait to urge.

Shaking his head, Zhang Yue put the test tube back on the table next to him and began to conduct the test.

As for the hair growth essence produced by the strange man just now, it is really not Zhang Yue's nonsense, it is indeed an unexpected gain, and the hair on the head of the kelp monster is really kelp, a very special mutated kelp.

In the previous life, Zhang Yue didn't know whether the kelp on the earth had an effect on hair growth, but Zhang Yue had studied the kelp in this world, and it really had no hair growth effect, who would have thought that this mutated kelp hair would really have such a good effect.

However, because of the particularity of Saitama itself, Zhang Yue is actually not optimistic about the effect of this hair growth essence, which is already the best hair growth in history......
