"Wow, even though I did it myself, this is a masterpiece......"

Staring at the cave in front of her, Ji Yuehua, who was wearing a gas mask, only felt that the muscles in her face twitched a little.

Time was the day after he had made up his mind to stab the Calambula.

On the way to the sea area where the main battlefield is located, Ji Yuehua took out all the poisons that had been made a long time ago against alien creatures, and then improvised some mixing work. Needless to say, this is to develop a formula that can poison the most alien creatures and be the most lethal.

Because there is no test bench, Ji Yuehua can only debug with general impressions and feelings. After arriving, he spent another two hours experimenting with different Calamity Beasts in order to ensure that the potions would not mutate into strange effects after mixing, such as enhancing the physical strength of the "Calamity".

Who knows, the results of the experiment turned out to be beyond his imagination.

Originally, Ji Yuehua was just thinking about increasing the toxicity of the potion to see if he could come up with something highly poisonous that could poison the A-Rank "Calamity Beast" in one second. Who knows, after trying more than a dozen mixed formulas, he was beaten by him to concoct a purple poison———— although the potion did not significantly change the effect of the individual "Calamity", but in terms of transmission ability, it has increased several times, and in conclusion, the lethality has more than doubled.

In order to further confirm the effectiveness of this poison, Ji Yuehua sent the formula of the potion to Yayi Yonglin by email, and continued the experiment in the rear of the "Calamity Beast".

Because he wears a "masking bracelet" on his hand, he is not visible to ordinary alien creatures.

Ji Yuehua swaggered into Island 6 on the right, and then placed a device to convert potions into gas and a reconnaissance drone in a cave with about 200 "armored spiders" and "spider larvae", and only activated the device after he walked out.

The results are quite impressive.

In just half a minute or so, the "spider larvae" wrapped in poisonous gas had begun to crumble. After three minutes, all the "spider larvae" were lying motionless on the ground. Twenty minutes later, even the adult "armored spiders" began to be unable to withstand the poisonous gas.

These "armored spiders" tried to escape from the place that they had established by themselves and had been their stronghold twenty minutes ago, but when they arrived at the cave, they found that the passage to the outside had been blocked by Ji Yuehua.

Forty minutes later, even the last adult "armored spider" fell to the ground.

After repeatedly confirming that there were no enemies standing in the cave through the remote-controlled drone, Ji Yuehua put on a gas mask for herself, and then dug up the reserved secret passage and walked into the cave to personally test the results.

He was quite satisfied with the results of the test———— the "armored spiders" and "spider larvae" did not collapse due to coma or some other reason, but did go to the underground Yellow Spring.

"Now that we know that even if it is converted into gas, it will not affect the lethality, so let's simply carry out a biochemical attack on the entire island...... No, you can't be so hasty. Let's honestly wait for Sister Yonglin's reply. ”

After coming out of the cave, Ji Yuehua touched her chin and fell into deep thought.

It is not yet known what effect this thing will have on other high-level "Calamity", and it would be bad if it had the opposite effect.

The reason why he chose the "Armored Spider" as the subject of the experiment was also because if he was a B-Rank "Calamity", even if something really went wrong, he was confident that he could quickly suppress the situation.

Although I don't know when I will have to wait until I get a reply from Yayi Yonglin, it is better than accidentally creating a large number of unusually powerful mutants and then falling into the desert and having to flee.

"According to the information given to me by Sister Yonglin, I remember that there are about 570 "calamity beasts" on this island that can be called combat power, right? Excluding the 120 "armored spiders" that have already reached adulthood, and before that, about 30 unlucky ghosts that I regarded as white rats, that means that there are still 420 ......"

There wasn't really much that could be done during this time until he got a reply from his genius's former boss.

It's also impossible to waste your limited precious time on things like being in a daze. So, there are really only two options in front of you.

Either they continue to find some enemies who are not too harmful to be white mice, and while waiting for the test results of their former boss, they slowly expand the scale and scope of the experiment in a controlled manner. Either that, use the old method before retirement, take out a saber and bow and arrows, and deal with the enemies in front of you in a down-to-earth manner.

If you say which one is more efficient, you don't have to think about it to know that it's faster to cut the monster directly with a knife.

Originally, poison or something was used by him as a weapon because he could pick up multiple enemies at once in a silent situation. If you need to be careful about the effective scope and carefully select the target audience, it is equivalent to putting the cart before the horse to a certain extent.

"That being said, I wonder if that guy will be here?......"

If you compare the use of poison with a knife and the direct use of a knife to cut monsters, if there is any advantage to the former, it is that it is almost negligible in terms of physical exertion.

Although it required a certain amount of physical strength to set up a device that released poison gas without being detected, the combination of stealth and aura blocking had greatly reduced the difficulty, at least for him who had survived the special training of the Eastern Canglong and crossed the mainland of the Republic of Sounion and the Inland Sea in an hour.

What's more, because the "battle" itself is not established, there is no possibility of injury———— so he can ensure that he is always in a state of perfection, even if he encounters the highest level S-Rank "Calamity" in the future.

"Hahaha, I would be bothered by this kind of thing, and I've changed it......"

If it had been in the past, he would have fought those alien creatures at all costs, even if he was scarred on his body.

If you want to describe it, it is like a sharp kitchen knife to see who cuts whom, pursuing efficiency supremacy, as long as it is beneficial to "one's own side" will do it.

It's just that......

When he thought of his agreement with Yayi Yonglin, and thought that there were still people waiting for him to return at home, this almost cursed motivation faded a lot.

"There's really no way, take your time......"

I let out an exclamation that even I thought was a little stupid.

As if she wanted to cheer herself up, staring at the blue sky above her head, Ji Yuehua stretched hard.
