Sign in, people are on an isolated island, and they just built a luxury villa by themselves

Chapter 915 The essence of dead air, double, submarine template
The Alliance of Survivors who had been collided by the island of the undead immediately lit a fire according to Xiao Yi's prompt.

A wall of fire has formed at the junction of the two islands!
After observing for a period of time, they found that the dead air did not continue to spread forward.

"Big Guy's method works without the constant gardener's work!"

"Boss, can you explain what's going on?"

"Yeah, why was it possible to block the dead air by planting grass at the beginning, but the invasion speed of the dead air became faster and faster?"

Xiao Yi explained: "I took the soil and air on the undead island to the laboratory for testing, and the results just came out. This so-called dead air is actually a kind of microorganism that proliferates very quickly. Nutrients are used to proliferate themselves, and this kind of microorganisms are not resistant to high temperatures, so as long as there is a firewall, they can prevent them from continuing to spread to our side!"

"Lying grass, what is this? Technology changes destiny?"

"At first I thought it was a fantasy, but now it has turned into something close to science?"

"The boss is the boss. At this time, he can think of using scientific experiments to study this undead island!"

"What I'm even more curious about is that the laboratory that the boss built can even do microbiological experiments, which is too advanced!"

"The high-end items in the hands of the boss have never been missing, but we have never seen them!"

"That's right, even the resorts and resort hotels we've seen, you don't know where the big guy came from!"

"That's true, but I want to ask the boss, you said that the bacteria can use the nutrients in the plants, will they infect the human body and turn people into mummy?" Someone asked curiously.

Xiao Yi looked through the test report he had just received, and then replied: "It cannot infect living organisms, and plants are susceptible to infection at present."

"That's good, at least you don't have to worry about people being infected by those bacteria."

"Now that I have a solution, I suddenly feel relaxed. I'll take a nap first, and I can't stand it anymore!"

"If you still dare to rest, you are not afraid of being touched under your bed by the undead and telling you to get up and pee!"

"Lying on the grass, there is actually someone under my bed! Who are you!" The person sent a voice on the island tablet, which has not been closed yet.

"Brother, do you believe me when I say I'm here to fix the water pipes?"

"Shameless! Die with me!" The man seemed to realize that the voice on his island tablet hadn't been turned off, so he turned it off immediately, and the voice stopped abruptly.

"Hahaha, I didn't expect to hear such a big show at this time!"

"I want to order a song for him, love is a ray of light, so green that you panic!"

"Don't be like this, everyone, maybe they are really here to repair the water pipes!"

"Okay, you guys continue to watch the show, I'm going to fight zombies, I wish everyone good luck, don't meet those undead who are completely uncertain!"

Xiao Yi notified all the sub-islands to prepare all kinds of incendiary materials, so that the wall of fire would be ignited as soon as the collision occurred.

It wasn't until this time that Xiao Yi had a chance to breathe a sigh of relief, and then secretly said: "System, sign in!"

It's past midnight now, and it's time to sign in.

"Successful sign-in, reward: small submarine template (SSS level)*1."

"Trigger double harvest, get supplies: small submarine template (SSS level)*2."

Seeing two system prompts in a row, Xiao Yi was stunned for a moment, and then secretly said happily: "The double state has been triggered again!"

Xiao Yi immediately sent a message in the mobile phone group: "Let me do the harvest today!"

Anyue and the others immediately understood what Xiao Yi meant, and they all responded.

Xiao Yi got up and walked towards the undead island. Looking at the still dead island through the wall of fire, he frowned.If the fire wall can block the death energy, and the undead creatures will not attack if one of our own cannot pass through it, then wouldn't it be enough to just guard it like this?
"It shouldn't be that simple!" Xiao Yi shook his head and thought to himself.

Jiang Yuntian walked over from the side, saw Xiao Yi shaking his head, and asked, "Island Master, did you find any problems again?"

"No." Xiao Yishu replied with a sigh of relief, "It's because I didn't find the problem that I'm a little uneasy!"

Jiang Yuntian was stunned, and immediately understood his worry: "That's true. The enemy rushed up directly, but there is nothing to worry about. Now we don't move, and they don't move. I always feel that some conspiracy is brewing, but we have no idea."

Xiao Yi nodded, and then said: "Let the soldiers take turns to be on duty. If there are no special circumstances, let everyone rest first!"

"Yes!" Jiang Yuntian stood at attention and saluted.

Xiao Yi waved his hand and inspired Huichengshi to return to his bedroom, but An Ran was there.

"How's the situation?" Seeing Xiao Yi's return, An Ran asked hastily.

Xiao Yi briefly explained the situation on the front line, and An Ran was stunned.

"There really are undead, how can those skeletons move?" An Ran couldn't help asking.

"I really don't know that!" Xiao Yi shook his head helplessly.

An Ran said happily: "Fortunately, you thought of asking the laboratory to check the soil and air there, otherwise we would have to keep exploring."

"I also have no clue, so I can only use the resources I have to explore this unknown enemy!" Xiao Yi smiled wryly.

"You've done a great job!" An Ran hugged Xiao Yi, and said, "If it's someone else, they're probably still in the dark!"

Xiao Yi shook his head slightly, and then asked, "Is the super synthesizer with you?"

"Well, do you need it now?" An Ran asked back.

Xiao Yi nodded, and An Ran immediately went out to get the super synthesizer back.

Xiao Yi took out the two small submarine templates from the system space, and synthesized them using a super synthesizer.

"The synthesis is successful, and the materials obtained: medium-sized submarine template (SSS level)*1."

"Sure enough, the small submarine template is already the top SSS level known so far. It is impossible to increase the level by synthesis, but it can increase the type level!" Xiao Yi was overjoyed.

Then, Xiao Yi immediately used it on the island tablet.

"What is this?" An Ran asked curiously.

"The submarine template is still a top-notch medium-sized submarine template." Xiao Yi replied with a smile.

"You actually got the template of the submarine!" An Ran widened her beautiful eyes in shock.

Xiao Yi nodded.

"That's amazing! Are you going to build a submarine now?" An Ran asked curiously.

"Don't build submarines now, now is suitable for building humans!" Xiao Yi hugged her while An Ran exclaimed.

At three or four o'clock in the morning, even if the submarine is built, it is not possible to visit the submarine now.

At night, you should do some work that you should do at night!
