I, Kizaru, only came to the chat group after I became invincible

Chapter 409 The Straw Hat Pirates!
Over the next few days, the treatment proceeded smoothly.

Every morning, Chopper would check the plants he had treated the previous day and adjust the treatment plan according to their recovery.

"This red clover has a serious lead poisoning problem."

He carefully observed the symptoms of the plant.

"The concentration of the antidote needs to be increased, and more vitamin C needs to be supplemented."

Sanji immediately adjusted the formula of the nutrient solution.

"I added natural sources of vitamin C, such as citrus extract, to the nutrient solution."

"This is both safe and effective."

Robin is also constantly learning and researching.

"I discovered that this spiny cactus has a special resistance to arsenic."

"Perhaps its genetic characteristics could be utilized to help other plants enhance their resistance to toxins."

Frankie, on the other hand, was constantly improving the equipment.

"I installed an automatic analysis system on the purification device."

"Now, it can automatically select the most suitable antidote based on the type of toxin in the soil."

Usopp's tools also became increasingly sophisticated.

"This new detector can detect even minute amounts of toxins."

"The accuracy has increased tenfold!"

Nami adjusts the weather every day according to the needs of the plants.

Sometimes it's warm sunshine, sometimes it's gentle rain.

"These newly sprouted purifying plants need more sunlight today."

"Thunder Sky - Clear Skies!"

Luffy and Zoro are taking on more and more physical tasks.

As the scope of treatment expands, the amount of soil that needs to be treated increases.

"Rubber Rubber - Super Dig!"

Luffy has developed new techniques, greatly improving his digging efficiency.

"Three-Sword Style - Precision Cutting!"

Zoro is also able to handle various complex terrains more accurately.

Thanks to everyone's joint efforts, the polluted area is shrinking day by day.

The plants that had withered and turned black began to revive.

Tender green buds sprout from the withered branches, and vibrant flowers bloom anew.

The purified land has regained its healthy brown color and exudes the fresh scent of earth.

“It’s amazing!”

The ancient tree was so moved that it shed tears.

"I thought I'd never see these children recover!"

"This is the result of everyone's joint efforts."

Chopper said modestly.

"Everyone played an important role."

However, the treatment process was not smooth sailing.

On the fifth day, they encountered a serious problem.

"Something terrible has happened!"

Usopp rushed over to report.

"An anomaly has occurred at the center of the contaminated area!"

Everyone rushed to the scene and found that the situation there was indeed very strange.

A huge black patch appeared on the ground, emitting a strong toxic gas.

The plants that had just recovered began to wither again.

"What's this?"

Nami covered her nose and asked.

"The smell is awful!"

Chopper immediately began the test.

"The toxin concentration is ten times higher than before!"

"And the composition is even more complex!"

"This should be the source of the toxin."

Robin analyzed.

"It's probably the deepest part of the mine, where the toxins are most concentrated."

"As surrounding toxins are cleared, the pressure here decreases, causing deeper toxins to surface."

"What should we do?"

Luffy asked anxiously.

"If we don't treat this area, all the treatments done elsewhere will be wasted!"

Chopper took a deep breath, a determined expression on his face.

"It's alright, no matter how strong the toxin is, I will cure it!"

"This is the doctor's responsibility!"

He began to reanalyze the composition of these extremely potent toxins.

"Sure enough, the toxins here are not only more diverse, but they have also undergone chemical reactions."

"A more dangerous compound was formed."

"A completely new antidote is needed."

Sanji immediately asked:

"Do you need me to prepare any special nutrient solution?"

"This time it's not a nutritional issue."

Chopper shook his head.

"These toxins are too potent; a more direct neutralization reaction is needed."

"I need to create a powerful neutralizing agent that can directly break down these compounds."

Frankie also stated:
"Just tell me what equipment you need!"

"I can build any complex device!"

"I need a sealed reaction vessel."

Chopper pondered a solution.

"It also needs a precise temperature and pressure control system."

"This neutralization reaction must take place under specific conditions; otherwise, it may produce even more dangerous substances."

Frankie immediately began designing.

"No problem! I'll build a super reactor right away!"

Meanwhile, Robin is also researching how to prevent the toxin from spreading again.

"We need to establish a cordon around it."

"Planting special plants can create a natural barrier against toxins."

Usopp, on the other hand, created more advanced protective gear.

"This gas mask can filter 99.9% of toxic gases."

"There are also protective suits that can prevent toxins from being absorbed through the skin."

Nami began to adjust the wind direction to prevent the poison gas from spreading.

"Thunderbolt and Heavenly Fire - Directional Flow!"

She created a special airflow to contain the poison gas within a fixed range.

Luffy and Zoro were in charge of digging to completely expose the source of the toxin.

Deep inside, they discovered a massive toxic mineral vein.

Various colored toxic minerals were piled together, emanating a terrifying aura.

"This is it!"

Chopper pointed to the mine and said.

"As long as these toxic mines are completely neutralized, the entire pollution problem can be fundamentally solved!"

After two days of intensive preparation, Operation Super Neutralization began.

The reactor that Frankie built was carefully placed above the toxic ore vein.

Chopper, dressed in state-of-the-art protective gear, personally operated the complex neutralization process.

"Begin adding the first neutralizing agent."

He carefully pressed the button.

A violent chemical reaction immediately began inside the reactor.

Various colors of light flashed, accompanied by hissing sounds.

"Temperature is normal, pressure is stable."

Frankie monitored all the indicators.

"The reaction is proceeding smoothly!"

"The toxin concentration has begun to decrease!"

Usopp reported the progress through the monitoring device.

"It's dropped by 20%, 40%, or even 60%!"

The entire process lasted six hours.

When the last flash of light disappeared, the terrifying toxic mine vein vanished completely.

Instead, there was a pile of harmless mineral residue.

"Success!"

Chopper jumped up excitedly.

"The toxin concentration has dropped to a safe level!"

"Very good!"

Everyone cheered.

After ten days of arduous treatment, the forest pollution problem on Kasuga Island was finally completely resolved.

The polluted area has been regrown with green plants, and the air is filled with a fresh floral fragrance.

The land regained its healthy color, and the small animals returned to the area.

"Thank you. Thank you so much!"

The ancient tree was so grateful that it couldn't speak.

"You not only saved my forest, but you also saved my heart."

"It made me believe in the goodness of humanity again."

"You are welcome!"

Luffy grinned.

"That's what a partner should do!"

"Moreover, this treatment taught me a lot of new knowledge."

Chopper was also very happy.

"Plant medicine is so interesting!"

"I will study this topic more in the future."

The ancient tree suddenly remembered something.

"By the way, the island's residents should be able to return now."

“I’m going to apologize to them and invite them home.” “That’s great!”

Nami said happily.

"That way, Kasuga Island can regain its vitality!"

"but."

"The ancient tree said earnestly."

"I will work with the residents to develop new rules."

"Destructive development will absolutely not be tolerated again."

"Human beings and nature must coexist in harmony."

"That's a great idea."

Robin agreed.

Only through balanced development can lasting prosperity be achieved.

A few days later, the residents of Kasuga Island gradually returned to their homes.

When they saw the forest come back to life, they were all moved to tears.

"Our home is back!"

"The forest is even more beautiful than before!"

With the mediation of the ancient tree, the residents reached a new agreement to coexist with the forest.

They pledged to prioritize environmental protection and develop eco-friendly industries.

The ancient trees also agreed to live in peace with humans and work together to protect this beautiful land.

Before they parted, the ancient tree gifted them some special plant seeds.

"These are the seeds of purifying plants."

"The ancient tree said."

"If you encounter similar pollution problems elsewhere, you can use them to help with remediation."

"Spreading green and hope is our shared mission."

Chopper carefully put the seeds away.

"I will keep it safe!"

"If I have the opportunity, I will definitely use them to help more places!"

Amidst the cheers of the residents, the Wanli Sunshine set sail once again.

The Thousand Sunny had only been sailing away from Kasuga Island for less than an hour when it heard a loud rumbling sound behind it.

Luffy was enjoying the sea breeze at the bow of the ship when he was suddenly drawn to the noise.

"Huh? What was that sound?"

He turned and looked toward Kasuga Island, where he saw thick black smoke rising in the distance.

Orange-red flames flickered in the smoke, indicating an explosion had occurred.

"not good!"

Nami immediately picked up the binoculars to observe.

"Something seems to have happened on Kasuga Island!"

"I saw a lot of smoke and fire!"

Others also came up to the deck to check the situation.

Through their binoculars, they could clearly see the town on Kasuga Island burning.

"Those residents who just returned home!"

"Chopper said worriedly."

"Are they in danger?"

"And there's the old tree!"

Luffy's expression turned serious.

"We have to go back and check!"

"Frankie! Turn around!"

"receive!"

Franky immediately maneuvered the Thousand Sunny to change direction.

"Full speed back to Kasuga Island!"

The Thousand Sunny sped toward Kasuga Island at top speed.

As they got closer, the situation on the island became clearer.

"Those were not accidental fires!"

Zoro gripped the hilt of his sword tightly.

"Someone is attacking the islanders!"

Indeed, through the binoculars, one could see a group of armed men wreaking havoc in the town.

They set houses on fire, looted property, and chased after fleeing residents.

"That damned bastard!"

Sanji gritted his teeth in anger.

"How can you treat the islanders who have just settled down like this!"

Who are these people?

Nami asked confused.

"They don't look like navy personnel or pirates."

"Judging from their attire, they should be mountain bandits."

Robin carefully observed the attackers.

"And there are quite a few of them, at least over a hundred."

Who cares who they are!

Luffy clenched his fists in anger.

"Anyone who dares to bully our friends must not be forgiven!"

The Thousand Sunny quickly arrived at the port of Kasuga Island.

The port was in a mess; several fishing boats were burned, and the docks were littered with the remains of looted ships.

"Let's split up!"

Luffy jumped off the ship and shouted instructions.

"Zoro, Sanji, Chopper, come with me to town!"

"Nami, Robin, Franky, head over to the forest!"

"Usopp is providing support from the high ground!"

"Mr. Borsalino is in charge of handling emergencies!"

"learn!"

Everyone immediately began to act according to Luffy's instructions.

Luffy and his crew rushed towards the town.

At the entrance to the town, they encountered a group of residents who were fleeing.

"What happened?"

Sanji hurriedly asked an injured old man.

"It's the Black Wolf Mountain Bandit Gang!"

The old man said, his voice trembling.

"They suddenly attacked our town!"

They said they were going to steal all our property!

"The Black Wolf Mountain Bandits?"

Chopper asked, puzzled.

Why did they attack you?

"Because...because they heard we've discovered treasure here."

Another young resident explained.

"A few days ago, someone spread a rumor that there is an ancient treasure in our forest."

"So these bandits came to rob us."

"Treasure?"

Zoro frowned.

What treasure could be found in the forest?

"Someone must have misrepresented our work on healing the forest."

Luffy analyzed.

"Some people might see that we're using a lot of expensive medicines and equipment and assume we're digging for treasure."

"Whatever the reason!"

Sanji said angrily.

"Robbing innocent civilians is unforgivable!"

They continued deeper into the town.

They soon encountered the first group of bandits.

These bandits wore tattered leather armor, carried various weapons, and looked fierce and menacing.

"Oh, a few more brats have arrived?"

The bandit leader said with a sneer.

"If you know what's good for you, get out of here right now, or we'll take all of you too!"

"You bunch of trash?"

Zoro looked at them coldly.

"A piece of trash who's not even as good as a pirate dares to act arrogantly here?"

"What did you say?!"

The bandit leader was enraged.

"You brat! Get him!"

A dozen or so bandits rushed up at once.

However, their strength is worlds apart from that of the Straw Hat Pirates.

"Three-Sword Style - Demon Slash!"

Zoro took down five or six bandits with a single slash.

"Demon Wind Kick - First Meat Shot!"

Sanji kicked the remaining few away with his flaming foot.

"Rubber, rubber—machine gun!"

Luffy's fists rained down, knocking down the last bandits.

The entire battle lasted less than thirty seconds.

"That's incredible!"

The bandit leader looked at them in fear.

“Who are you?”

"We are the Straw Hat Pirates!"

Luffy said proudly.

"I'll teach you bullies who prey on the weak a lesson!"

"The Straw Hat Pirates?!"
