Since the merfolk moved away from the West Sea, the fantasy-level mermaid hometown no longer exists, leaving the mermaid island still under the protection of the temple enchantment, alone in a poisonous sea area.

At the moment, the Kraken has no interest in this mermaid remnant, whether it is the god-level enchantment or the mermaid saintess, it is undoubtedly a hard bone to gnaw! Moreover, if the sea is the absolute home of marine life, then the mermaid clan is a well-deserved royal family on the sea, as the god race that once ruled the sea, no one knows how many hole cards they hold in their hands, if the strong attack leads to overturning, it will undoubtedly completely bury the current good situation of the kraken, at least until the kraken emperor recovers to the peak of the demigods, the kraken will definitely not risk on the mermaid clan.

The teleportation array on Mermaid Island has not been completely closed, but now there is only one place, that is, the hometown of the new mermaid in the five-color sea area, to go to Mermaid Island, it is just a teleportation array for Wu Yi, and it will not take two minutes before and after.

Coming to Mermaid Island again, the surrounding waters have changed greatly, the original dark green, emitting a foul smell of sea water has turned pale green, it is obvious that the toxins in the sea water have been greatly reduced, I believe it will not take long to return to a normal state.

"Congratulations, Grand Master!" Mermaid Island is not big, nearly two-thirds of the area is occupied by the goddess hall and goddess statues, this goddess hall is the same as the ancestral witch hall of the witch clan, foreign races are absolutely not allowed to enter, so the mermaid clan gave Sun Simiao a small medicine house next to the temple for Sun Simiao to live and study, so it is easy to find Sun Simiao

"Haha, the lord is coming so quickly." At this time, Sun Simiao was guarding a huge Dan furnace, refining the pill.

"Isn't this here to ask you when you will go back! Your promotion to Grand Master is a big deal for Hulu City, and you have to do a big deal. "Last time, taking advantage of the opportunity of Zhu Rong's promotion to demigod, the territory held a big celebration and brushed the hearts of the people, this time Sun Simiao was promoted to the grand master, and Wu Yi planned to do it again according to the same specifications.

"There is no need for celebrations, the old man doesn't like that kind of occasion very much, this time I go back, the old man plans to compile a pharmacopoeia." Sun Simiao refused directly without thinking about it.

Compilation of pharmacopoeia?

It's good to compile a pharmacopoeia! Think about the effect of "Heavenly Creation", think about the effect of "Wu Mu's Testament", the "Thousand Golden Prescriptions" of the King of Medicine will definitely not be bad, right?

"Alright then, as you mean by the old." Wu Yi didn't force it, but there was one more important thing, that is, to increase the acquisition of various high-quality medicinal materials, and then Sun Simiao would definitely research a batch of new pill formulas. When it comes to the step of the Great Grandmaster, the principle is that there are no unusable medicinal materials, and at this step, it is very easy to develop the Dan Fang, and in person, the kind of top-level Dan Fang that can become a masterpiece still needs time to precipitate.

"By the way, this thing should be of some use to the lord." While speaking, Sun Simiao threw Wu Yi a black gourd. Sun Simiao likes the specialty gourd of Hulu City very much, all the pills he refines are held in this gourd, and a very small number of mutated gourds also have the special effect of "raising pills", stored in this gourd for a certain amount of time, and the pills in it can improve a certain quality.

Wu Yi, who caught the gourd, pulled out the gourd stopper, tilted it slightly, and rolled out two pills and landed in the palm of his left hand, the pills were also pitch black, and the surface was sealed with sodium.

Hydra Venom Pill (Gold): A deadly poison that even the undead can't escape when it seals its throat with blood.

Golden quality elixir!

This was the first time Wu Yi had seen a golden-quality elixir, although it was a poison! Most of the golden-quality things belong to the scope of the gods, and the Hydra Poison Pill in front of him is no exception, the Hydra is a god-level demonic beast, and this Poison Pill is also made by Sun Simiao refining the snake venom of the Hydra, so this is a masterpiece!

"The lord must be careful when using it, once the sodium seal is broken, the poisonous gas will be emitted immediately, and it is easy to die first." Sun Simiao didn't forget to remind.

This thing......

Wu Yi was a little entangled holding the gourd, this poison pill is theoretically except for the gods, whoever touches it will die, even if it is a demigod, it is simply a big killer! But how to use it? The best way is to throw, using the force of the impact to break the sodium seal on the surface of the poison pill, so that the user can also be in a safe position to avoid being affected by the poison gas.

However, this method is difficult to work for the powerhouse who has the domain, the quality of the poison pill is too small, even if Li Yuanba is allowed to throw it, the speed will not be too fast, and there is no way to break through the defense of the domain. If it exploded on the periphery of the field, then with the spread speed of the poisonous gas, the opponent would have already run away.

As for poisoning, think about the scene of the mermaid's hometown at the beginning, after the poison pill is allowed in the water, it will probably become like that again, no, if it is a small amount of water, it will definitely be more serious. That kind of water, as long as you are not blind, let alone drink it, you can't even get close, right?

"Great Grandmaster, after breaking the sodium seal, what is the maximum range that the poisonous gas can cover?" In the end, how to use it, you still have to know some data first, otherwise the result may be to hurt the enemy by 1,000 and lose yourself by 800.

"Ten meters in radius! If it melts into water, it can exceed a 100 meters, but be aware that if it melts into water, the polluted waters will not move with the push of waves or magic, nor will they disappear from the water for a long time, unless they are refined again, or absorbed by enough organisms. ”

Hydra venom is not something that anyone can refine, Sun Simiao can do it because he completely grasps its toxicity, and after he refines it, the snake venom of Hydra is stronger than when it was released by the Kraken, although the polluted sea area is wide, but the lethality is not strong, and even ordinary mermaids can't be directly poisoned, let alone demigods.

And Sun Simiao also got the specialty of "poison mastery", as well as the title of "poison king", although Sun Simiao can't be called a master now, but he wants to release the poison, it is definitely a big killer, and at the same time, the poison pill he refines will be sharper.

"So dangerous?" Wu Yi was frightened, if this thing was thrown in the five-color sea area, or the Kraken tribe, it would explode directly. Wu Yi poured out all the poison pills, there were only twelve in total, but unfortunately, it was difficult to carry out the extermination operation with only this point.

"It's dangerous, so you have to be cautious when using it."

"I'll take notice." Wu Yi put the black gourd into the sighing ring with some regret, this poison pill needs perfect timing to use, but such a time is not easy to find. Using dead people to carry out suicide attacks? However, the dead soldier must not use the strong, nor can he use those talents with strong potential, if it is just an ordinary soldier, then it is still the same problem, and it cannot threaten the real strong.
