In a dry and open area of the cave tunnel, several people dressed as fishermen and crew members lay on the ground, moaning and wailing, most of them men in the prime of life, their expressions twisted and painful, and they were still sweating profusely even though the temperature in the cave was extremely low.

Among the people lying on the ground, only one old man who was slightly hunched was relatively calm, but it could also be seen that the old man's legs were swollen, and there were several small black and blue dots faintly shuttling in them.

A young man of about fourteen or fifteen years old worriedly held a potion and a knife in his hand, and applied the medicine to the ordinary people who were moaning and screaming.

"Ladies and gentlemen."

Occasionally, he would reluctantly remind: "Please be quiet, this is a cave area, the sound can travel far away, if it attracts other magical beasts, it will be really dangerous." ”

The blonde boy is none other than Isengard.

When the South Seas were mutated, he, Master Gosai, Ian, Shark, and the pirate captain were swept into the ruins by the winds that opened the ruins.

Because Master Gosai is physically exhausted, he can only be on top of him, urging sublimation skills and talisman accessories to protect everyone.

He succeeded, but in the final analysis, he was still the first level, and he couldn't be perfect, and he still caused everyone to scatter, and he could only protect the already unconscious Master Gosai from falling into the ruins.

Because of the protection of the talisman ornament, he soon woke up, and after observing the environment, he began to try to find an exit in the direction of the wind.

The tunnels lead in all directions, deep and dark, and after searching for a long time, Isengard has not had time to find the exit, and first encounters a group of ordinary fishermen and merchant merchants who have been attacked by demonic beasts.

The changes in the South China Sea are not limited to the far sea.

At the time of the change, large and small eddy openings appeared in the area of Odell Reef, around the Sighing Cliff, and even in the northeast sea, dragging many ships and outsiders into it, and involving many ordinary people.

The tide was relatively turbulent only at the main entrance, and the small intersections in other places were quite gentle, and even some fishermen's fishing boats were not broken.

Although Isengard lacks emotional intelligence and is a little naïve, he is not stupid enough to save people without thinking, and if they can find those relatively gentle small entrances, it will definitely be of great help to their current situation.

He shot back at the strange lobster, a giant shrimp with no carapace but a layer of tough grease on its body. This giant shrimp is the main dish of the top whole shrimp feast of the rich in big coastal cities, and the delicious shrimp oil is even more delicacious, but it is difficult to say who is the delicacy at the moment.

After killing the monster one-on-one, Isengard was stunned to find that almost all the ordinary people who had been affected by the water foam spewed by the lobster before, and even Master Gosai began to have a high fever, and extremely obvious bulges and cysts appeared on his body.

"This is a parasite, ordinary anti-poison and anti-insect drugs are not useful, but rather a tranquilizer that slows down blood flow, an anesthetic that anesthetizes nerve perception can reduce the frequency of activity of these unknown parasites."

Armed with potions and knives, the boy deftly weaved his way through the moaning crowd, picking out pustules for them, killing the parasites that slowed down, and then cauterizing the wounds with fire to heal the burns.

At this moment, he entered a professional state, regarded everything as a biological alchemy experiment, but calmed down, and then calmly analyzed and dealt with it: "These parasites flow along the bloodstream, but their purpose is not to spread throughout the body, but to reach the 'brain-blood barrier' and enter the brain. ”

"It's a parasite that specializes in the nervous system, so anesthetics are the most effective."

After the treatment of Isengard, most of the infected patients have improved, but there is no cure. He couldn't find where the lesions were located in a short period of time, and even if he did, he wouldn't have enough time to cure them all.

Approaching an old man who was sweating profusely but breathing as gently as possible, the young man half-knelt in front of him, lifted his robe, and carefully observed his legs, which had been swollen to twice their original size.

Master Gosai had been silently observing his student's every move. He watched as Isengard analyzed the situation, dispensed drugs on the spot to treat the patient and performed pharmacological and biological analysis.

Although it was painful, he also smiled with satisfaction.

He thought that Ethan would be depressed because of his uncle's betrayal, but he didn't expect that at the critical moment, this kid could still keep his heart, always have pity, and not lose the basic skills of alchemy.

Yiyi may not be a good nobleman...... But a good student.

It wasn't until the boy came to him that the old man regained his original calm appearance.

"Teacher, mobilize essentia, suppress the blood flow in the lower body, and I'll deal with it."

Seriously said to Master Gosai, Isengard himself is not afraid of infection, the blood of the Eclipse Light Alchemy Inheritor is a special poisonous alchemy matrix, plus they themselves are an alternative possessed parasitic inheritance, it is almost impossible to be parasitized by other creatures.

So he can handle everyone's condition very comfortably.

“… Yes, Ethan, you're just getting a little bit of a look now. ”

The old man nodded slightly, then shook his head and said: "My leg is no longer good, in the process of being unconscious, this demonic beast-level parasite has corroded all the nervous system of my leg, cure it, it is better to cut it off, and then use the regeneration potion to grow another one." ”

"Is that so......" After a stunned pause, Isengard said firmly, "...... At the very least, you have to ease your pain a little. ”

"This is a blocking agent that I have configured, which can probably stop the parasite from being active for a while, and the other patients have responded very well and there is no risk."

"Hmm."

Master Gosai looked at the crowd whose screams had subsided, but their limbs and his legs were bulging and giving birth to cysts.

He frowned at first, wanting to say something, but finally sighed: "You saved them...... It may make them more painful. ”

"What?"

Isengard, who had seen too little, was a little dazed, and the old man, who had seen too many similar situations, just shook his head: "It's nothing, in the final analysis, it's also your kindness... And it's not necessarily hopeless. ”

Raising his head, when the young man injected himself with the blocking potion, Master Gosai raised his head, looked at the other side of the cave, and sighed softly: "I don't know what the situation is with this underground ruins, there are so many terrible parasites here, and I don't know how it maintains the group, and what about the other biomes..."

After a pause, he added, "Ethan, do you remember the direction in which Ian fell?" ”

"Nope."

Isengard thought for a while and shook his head slightly: "At that time, the wind and waves were extremely strong, and I did my best just to slow down and protect everyone. "However, seeing that these ordinary people can survive, I believe that Ian will definitely be fine."
