Xiao Yi continued: "because this island is likely to be left over by the last survivors, their island monuments have been buried by weathered buildings."

"Ah, isn't it that we need to dig it out a little bit? It's even more unrealistic!"

"Yes, it's very difficult for us to stop the undead invasion on the defense line. We have to go up and dig things. It's certainly not possible!"

"It's certainly unrealistic for you to go up, but you can use hot-air balloons, throw shells on the hot-air balloons and blow up the sand, so you can find the island monument!" Xiao Yi replied.

"Good idea!" People said one after another.

"And most survivors should put the island monument in the central position, so we just need to look for it in the core area!" Xiao Yi continues to remind everyone!

"Big guy, you've told us exactly what to do. If we can't finish this copy, it's really our problem!"

"Yes, I'll let them find the island monument!"

"Boss, after finding the island monument, how to remove the dead spirit on the island monument?" Someone asked.

Xiao Yi continued: "in fact, there are two options to find the island monument. One is to directly smash the island monument, and the other is to remove the dead spirit of the island monument."

"At this point, I just remembered whether throwing shells would blow up the island monument?"

"Are you stupid upstairs? When our naval battle was so fierce, which island monument have you ever seen broken by shells?"

"Yes, but why can we choose to occupy or break it when we touch the island monument?"

"You have to ask the world rules. How do I know? Stop talking. Listen to the boss, how to remove the dead spirit of the island monument?"

Seeing that they had discussed the results themselves, Xiao Yi stopped explaining and continued: "if you want to remove the dead gas, you must use a bactericide that can kill the microorganisms on the island monument. If you pour it on the island monument, it will automatically absorb it and maintain the drug supply. At the same time, you can't let the undead bury the island monument."

"Will the undead bury the island monument?"

"Yes, just as we will guard our own island monument." Xiao Yi replied with certainty.

"What else should I do after pouring the medicine?"

"Wait, it takes a day and a night to repair the island monument!" Xiao Yi replied.

"Still want to keep this state? It's too difficult!"

"Yes, I'd better break it directly. I think it's more convenient!"

"Yes, it's more convenient to break, but in that case, we won't have a lot of island monuments?"

"Less is twice less. Even now, it can reach an island monument per person!"

"I'm a little worried that these island monuments will be useful next."

"Since you have this worry, you should get rid of the dead spirit. According to the solution ideas provided by the boss, it should be no problem!"

"Well, I'd better try to get rid of the dead spirit!"

"No, there's another problem. We're talking fiercely here, but what about the medicine?"

"The boss must have ah, we can buy it directly!"

Xiao Yi saw that after everyone talked about bactericides, he actually called the laboratory and asked, "how many resources does this bactericide need?"

"Back to the island owner, we only need some power supply. We use equipment to synthesize these chemicals, and the dosage is very small!" The robot in the laboratory returned.

Electricity doesn't cost much here in Xiao Yi. Now nuclear power generation is completely surplus!

Since there is no cost, Xiao Yi said directly in the group: "two tons of medicine, one hundred cornerstones, two tons can remove the dead gas of an island monument."

"Great, I'll buy 18 tons. There are nine undead islands here! I'm going to purify them all!"

"I want 8 tons here. It's too troublesome to purify all, so I'd better leave half!"

"Boss, I want 6 tons first. I'll buy it when I run out!"

Xiao Yi handed this matter to Su Wan and asked them to contact Su Wan!

Many foreign forces have begun to buy from Xiao Yi. The purchase of Yi Tianqun is limited and can't buy many at present.

Those foreign forces can only buy from Xiao Yi themselves.

Xiao Yi directly doubled the price and bought it. Although he felt a little expensive, there was no chemical industry in those foreign alliances, so he couldn't make this bactericide at all. He could bite his teeth and buy it.

Looking at the fungicides that have been traded constantly, Xiao Yi said with emotion: "it's no wonder those chemical industries make so much money. Like cosmetics, it's estimated that some natural or synthetic substances can be put in a small bottle, and then they can be sold at a high price. What a huge profit!"

Of course, it is undeniable that the R & D of these things takes time and money, and they need to share the R & D cost equally with the final price.

Soon night fell, and all the island monuments of yiranpin alliance were in a state of self-healing. Although new undead creatures will not be refreshed at midnight today, what was refreshed yesterday is still there!

The pressure on the defense line was much less. They were in the mood to chat while attacking the undead creatures.

These undead creatures were fighting less and less. By midnight, the undead creatures were completely destroyed by them.

After receiving the news reported by Jiang Yuntian, Xiao Yi immediately ordered: "all teams enter the undead island to search. They can't fall into any corner to ensure that no undead creatures continue to exist!"

"Yes!" Jiang Yuntian replied.

Yiranpin alliance sounded the horn of counterattack!

At this time, other alliances are being attacked by underwater creatures!

The previous torpedoes have destroyed most underwater creatures, but there are still some fish that have escaped the net and began to attack the cornerstone of the survivor island.

"Didi, please note that the cornerstone of the island is being attacked. Please protect the island!" The island monument immediately began to prompt.

Seeing the location of the attack, they acted immediately.

Several people in a group, holding a long metal spear in their hands, rushed to the position where the cornerstone was attacked!

There are people holding a fishing net. Although the fishing net may not catch those advanced undead, it can at least entangle it!

"Ma De, fortunately, the boss provided us torpedoes during the day, which killed most of the underwater undead. Otherwise, it's really besieged now!"

"Yes, these undead people are totally irregular and attack everywhere!"

"No, they're going around our main island on my side!"

"It's hard to do. Do you have a better fishing net to rent?"

"I also need a better fishing net!"

Xiao Yi hasn't put on the automatic fishing net yet. A private chat message came over.

"Island leader Xiao, do you have a high-level fishing net? The underwater undead creatures here are S-class!" Emperor Lin sent a message for help.
