From the moment he became the Blue Silver Emperor of Douluo Continent

Shi Yin continued walking, scattering Blue Silver Grass seeds as he went.

On this frigid winter island, ordinary Blue Silver Grass cannot survive. To allow Blue Silver Grass to survive in this place, he needs to help these Blue Silver Grass mutate, at least to make them develop a certain level of resistance.

Otherwise, he would have to rely on his soul power to sustain it. Once he leaves, the planted Blue Silver Grass will die, which would go against his expectations for the Blue Silver Grass.

This was Shi Yin's first time encountering Winter Island, so he planned to stay in the Drum Kingdom for a while to study how to mutate the Blue Silver Grass to develop cold resistance.

In addition to this topic, he has also been researching the topic of aquatic blue silver grass.

This is a more important issue than the cold resistance issue, after all, there aren't many winter islands on the entire pirate planet, but the ocean area far exceeds the land area.

However, the research on aquatic blue silver grass is much more difficult than simply making blue silver grass cold-resistant.

However, for now, Time Silver still plans to find Wapol and get his hands on the Gluttony Fruit first.

Shi Yin didn't encounter many people along the way, and no one was curious about his arrival as a stranger.

Life is already exhausting enough, who cares about anything else?

And so, he walked unimpeded to the palace.

Although Wapol was a tyrant, he was clearly a tyrant who cared about his own life.

The small palace was heavily guarded.

It would be extremely difficult for Shi Yin to infiltrate using conventional methods, but those are the only conventional methods available.

With the aid of Blue Silver Grass, he can infiltrate from multiple angles, and if all else fails, he can even fly in.

Furthermore, although this is the Grand Line, it's not a place where powerful figures can roam freely. At least Wapol's guards aren't stronger than the pirates in the East Blue.

Shi Yin easily sneaked in and slipped all the way to the vicinity of Wapol.

There's no need to infiltrate any further; he's already seen the guy.

Fourth Soul Skill: Blue Silver Flower Blooms

The massive, thick blue silver grass vines, combined with the amplification of his blue silver domain, engulfed everyone within a hundred-meter radius.

The others were quickly killed, but Wapol was spared by Toki Gin.

Wapol tried to break free of his restraints by consuming Blue Silver Grass, but he soon discovered that he couldn't struggle at all.

If you want to devour the Blue Silver Grass, you need to be able to reach it with your mouth.

Unfortunately, Shi Yin still had some recollection of the Gluttony Fruit, knowing that it could devour everything.

To prevent this guy from swallowing his Blue Silver Grass, he simply hung it in mid-air, so its mouth couldn't reach anything.

He then stabbed the guy in the heart and quickly put him into his storage soul tool.

Not long after Wapol died, another Devil Fruit appeared in Time Silver's storage device—the Gluttony Fruit.

After doing all this, he leisurely found the royal treasury, casually searched it, and then turned and left.

For the next period of time, he stayed at the foot of the snow-capped mountains outside the small town.

Wapol's disappearance was not kept secret for long.

Yes, it's missing, not dead.

Shigin did not leave Wapol's body at the scene; instead, he disposed of the other people's bodies as well.

As the king of a country, he didn't want to face the navy's arrest warrant for the time being, so he had to keep a low profile.

As long as there is no body, death cannot be confirmed, and it will not attract the attention of the World Government and the Navy, at least not for the time being.

For now, we should try to keep it a secret as long as possible.

After staying here for half a month, Shi Yin finally completed the improvement of the Blue Silver Grass and cultivated a Blue Silver Grass that could resist the cold.

He sowed the new mutated seeds, which gave birth to a batch of the first generation of mutated Blue Silver Grass.

Only then can we say that the goal has been achieved.

As for the other type of marine blue silver grass, there is still no clue.

This direction of variation probably needs to be referenced from marine plants such as seaweed and kelp, and it can't be rushed in a short time.

In addition, it is estimated that drought-resistant varieties of blue silver grass will be improved and planted in arid and desert areas in the future.

But he'll deal with that later when he encounters it; he doesn't want to study it anymore right now.

I just want to rest for a while.

"Hey, tanuki, you've been staring at me for so long. Aren't you going to come out and say hello?"

He looked into the woods beside him, where a head was peeking out furtively.

When he looked over, the head quickly shrank back.

However, upon hearing his words, she immediately jumped out indignantly: "It's a reindeer! How do I look like a raccoon?"

"Oh, really? I didn't realize. You look just like a raccoon dog from every angle!"

Shi Yin teased the little guy.

This is Chopper, the Zoan-type Human-Human Fruit user in his commoner form.

In other words, it doesn't have any special form; it's just the most ordinary Human-Human Fruit.

She will be Luffy's ship doctor in the future, but she is probably still learning from Kureha for now.

Shi Yin has no need for doctors; if he wanted, he could be a top-notch physician.

So, when he was bored out of his mind, he decided to tease Chopper.

"It doesn't look like a raccoon dog, it's a reindeer, you bastard!" Chopper retorted loudly.

After saying that, he ran away.

Wow, you're so easily amused.

Forget it, he'll just continue spreading Blue Silver Grass.

Another day passed, and Shi Yin had planted Blue Silver Grass in most areas of the island, so he chose to leave.

Having stayed here for so long, it's time to leave.

Meanwhile, Chopper, who had run away, came back to find him.

Chopper finally met someone who didn't think he was a monster and wanted to be friends with him, but then he discovered that the person had disappeared. He searched for a long time but couldn't find him. After a period of disappointment, Chopper gradually forgot about him.

Kureha, however, after learning of this person's existence, connected Wapol's disappearance with him.

With such a small population in the entire Drum Kingdom, the arrival of outsiders would be very conspicuous. And coincidentally, at the same time he arrived, Wapol disappeared. She didn't believe there was no connection between the two.

However, she didn't like Wahlbo, so she didn't bother with it.

She also noticed the blue silver grass.

With so many unfamiliar plants suddenly growing on the entire island, it was impossible for her not to notice them.

After guessing that this was also his work, she began to analyze his purpose.

No matter how I analyze it, I can't figure it out. I just feel that this must be a kind of Devil Fruit ability, otherwise how could so many be planted in such a short time?

She even tried picking some Blue Silver Grass to analyze its medicinal effects, suspecting that Shi Yin might be planning to poison her in a covert manner.

She quickly determined that the blue silver grass was non-toxic and was just an ordinary cold-resistant plant.

Kureha couldn't understand it at all; she had no idea what his purpose was.

I just felt that this person was really mysterious.

Shi Yin, who had already gone far away, naturally had no way of knowing about her actions.

He wasn't afraid of being investigated for releasing the Blue Silver Grass, as there was nothing wrong with it to begin with.

These people couldn't have imagined that he was just casually trying out a location coordinate, and whether it would work was still unknown.
