One Piece: Don't Worry, I'm a Doctor - Chapter 35 - : Arrival

The Apocalypse is in full swing. Defiled - powerful creatures corrupted by the Great Collision - prowled the lands in search of prey. Unfortunately for them, the human race had long since retreated behind the secure walls of the Sanctuary of Everlast. During one of his regular excursions outside the Sanctuary, Alden is separated from Celeste. - his childhood friend and crush. In that moment, he came to regret never summoning the courage to confess. Somehow managing to survive thanks to some trickery, Alden awakens as a mage. Instead of receiving a normal power, he gains the ability to decay. What’s more, during his ascension, he received a vision from his future self advising him not to trust the Asterons - celestial beings who had saved his race from inescapable doom. Normally... such a revelation wouldn’t faze Alden. However, there was only one major problem with the declaration, though. Celeste was bound with an Asteron. And not just any normal Asteron... She had made a pact with one of the Divine Sovereigns.

He had four disobedient disciples, who now achieved success, won recognition and established their own sects.

The embarrassing thing is that it was him who drove those four out of his sect to make them independent.

But one day he had an incident and lost his cultivation. His life was hanging by a thread. Wandering around, he walked into his third disciple’s territory.

What should I do?

Mountains and seas can be tamed, days and nights can disappear.

Only you, the exceptional you, refuse to give up.

——

A man blessed with fortune, the best in his generation, had an accident and started anew; broken in body but firm in spirit, he now uses his wisdom to guide his evil disciples back to the right path.

After the final high school exams, Zheng Qing didn't go to the long-desired Imperial University. Instead, he packed his bags, hugged his fox, followed an enigmatic notice, and ventured into an unknown university.Here, there was no advanced math, English, or political philosophy; they were replaced with divination, astronomy, and the philosophy of magic.Extracurriculars here involved demon hunting,And the hobbies were curious and diverse.He would sail the sea of learning and climb the mountain of books.This bewildered young man started his tumultuous journey as a wizard.(Group created: Six Two Three Eight Five Eight Nine Three One, you're welcome to join.)

When Li Yu woke up, he found that he had traveled to the game world of “Avenue Eternal”.

At this time, there is still half a year before the player arrives.

The evil demon catastrophe has not yet begun, and the forbidden areas of death such as the rotten swamp, the golden desert, the ghost country of the Yinshan Mountains, and the boundless monster sea are still silent. The whole world is calm.

Li Yu took advantage of his foresight and took advantage of the opportunity to develop wretchedly.

After the game is launched, along the Qingshui River, players often see a senior NPC with a glittering ID fishing.

Whenever the players approached excitedly to chat to see if they could apprentice or trigger tasks—

“What? You want to worship me as your teacher?”

Li Yu shook his head: “Excuse me, your qualifications are too poor. But Pindao once lost a Chilong jade pendant in the zombie cave. If you find this thing, I can teach you a spell.”

“Do you want to learn alchemy?” Li Yu smiled slightly: “There is a group of evil cultivators in the Wugui Cave of Qilao Mountain, as long as you can eliminate the evil for the people, and bring their magical instrument Xinjin and copper bottle to me, How about Pindao passing on your alchemy skills?”

“You want to worship Zixia Sect?”

“Do you want to learn alchemy?”

“It’s all right.”

Li Yu said meaningfully:

“But you have to understand one truth, there is no free lunch in this world!”

…

It was not until hundreds of years later that many top figures fell and disappeared, and the players also changed one after another, but Li Yu was still active in the world of dry ground, and he was even about to rise through calamity.

Many players have to sigh: This NPC is too strong!
