[Legendary class + leveling progression + the only one compatible with potions + absolutely invincible + no female lead + ten injections a day, talent doesn't matter]
After transmigrating to a world where everyone changes classes, Chen Tian awakens a rare, legendary S-rank Potion Master class.
But fate plays a cruel joke on him: on the very day he changes classes, he is diagnosed with terminal cancer.
With at most two years to live, he locks himself inside a cramped rental apartment.
Everyone thinks Chen Tian is dead, but three years later, he makes a spectacular return with a super healing potion he developed himself.
It not only cures his cancer, but also accidentally grants him a survival ability on par with a tardigrade!
Instant healing from injuries, cell regeneration, incredible recovery...
Given a new lease on life, he decides to set out on the path to strength once more!
Before long, he has developed one world-defying potion after another: "Super Soldier Potion," "Trait-Stripping Serum," "Body Tissue Optimization Virus"...
Chen Tian becomes known to others as that madman "addicted to injections"!
Only Chen Tian knows that he is gradually transforming himself into a true god who is "undying, indestructible, and all-powerful"!
Years later, when an army of foreign races advances on humanity, they see Chen Tian, this "human-shaped good-luck charm," and are instantly dumbfounded.
The foreign races: "You should've told us you had a god like this guarding you!"
How should I put it? To put it mildly, the subject matter is novel. There are very few books on the market written by pharmacists as professionals. To put it bluntly, you are buying a dog's head in sheep's clothing, and you use the potion you make from beginning to end. It is still the same as the original warrior and assassin professions. There is no difference. You change the skin but not the meat, and you change the soup but not the medicine. In this pharmacist theme, if you can cure cancer, you can research and sell the medicine again. The same goes for super soldier genetic medicine. There are so many promising medicines such as transformation medicine and supernatural power medicine. You don't do it. You use it by yourself, give it to yourself, and then fight monsters by yourself. No matter how awesome your medicine is, can you have hundreds or thousands of people begging to buy your medicine? How fast can you develop it? Don't say that there is no backstage. If others are worried about it, just use the medicine to conquer cancer. You can find a wealthy businessman who has cancer and wants to live, and you will have the money. Find the official source of your super soldier gene, and you will have the connections, rights, money and money.
It's so long-winded, especially when I was just cured of cancer, I kept describing the condition of the pig's feet in nonsense words!
