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

Chapter 215 Building upgrade card, the speed of sweaty BMW
Seeing that people in the group mentioned him again, Xiao Yi immediately said: "Mass production can't be done yet, but it will definitely be possible in the future!"

"This is the boss, you are a real bull!"

"Boss, if you can sell us some in mass production in the future, the price will be slightly cheaper then, okay?"

"If it can be mass-produced, it will definitely be sold to the outside world. At that time, we still need everyone's support!" Xiao Yi said in the group.

"Great, I can't smell the clothes I've been wearing for a month!"

"Then just take it off, since there is no one else, wash it in the sea water, dry it and continue wearing it!"

"Do you think I didn't do that? I just rubbed it lightly, and it was ruined by me! Now I'm wearing a clothes riddled with holes!"

"I heard that someone opened clothes! It seems to be a gown or something!"

"Damn, so strong, who is so lucky?"

"I just heard that, whether it is true or not, I don't know!"

"It can be opened! But the probability is extremely low!" Xiao Yi said, "I only opened one piece after I opened it for a month!"

"Boss is really lucky!"

Seeing compliments in the group, Xiao Yi got up and left in front of the island monument, and walked to the living room on the first floor.

"Tonight, Wangcai and Dabai are mainly on duty. Unless two or more places are attacked at the same time, you can handle the rest yourself!" Xiao Yi said, looking at Dabai and Wangcai lying in the living room.

Dabai raised his head and nodded, while Wangcai yelled twice.

"If there is a situation where two places are attacked at the same time, call me in time!" Jiang Yuntian said.

"Woof!" Wang Cai responded.

"Everyone is quite tired today, let's all go back and rest early!" Xiao Yi said, "Uncle An, call Auntie and the others, don't be in such a hurry, you can work well after you rest!"

"Well, I'll call them!" Anyue replied.

"Old Yuan, take this bamboo and plant it in the manor first!" Xiao Yi handed over the bamboo that he had just traded to Yuan Nong.

Yuan Nong nodded, and walked to the manor with some SS-grade purified water.

After giving all these instructions, Xiao Yi returned to his room again, glanced at Yi Tianqun, and found that there was no useful news, and then fell down on the bed to rest.

Just after midnight, Xiao Yi vaguely heard the siren of the attached island monument in the lobby on the first floor.

But Dabai never came up to call him, which shows that they can handle it by themselves!

The next day, at 05:30 in the morning, Jiang Yuntian blew the assembly whistle again, and everyone assembled within 1 minute, and then Jiang Yuntian took them for morning exercises!

Xiao Yi got up to find Dabai, and asked, "How many times was the island attacked last night?"

"Ho Ho!" Dabai yelled a few times.

Xiao Yi nodded, and continued to ask, "Are they all at the same time?"

Dabai shook his head.

It turned out that from the early morning of yesterday to 05:30 in the morning, there were a total of 25 attacks by marine life, and they all came one by one, and there was no attack at the same time.

"Take a break first!" Xiao Yi patted Dabai, who lay down in the corner of the living room.

"Didi, the island is being attacked by marine life, please deal with it in time!"

As soon as Dabai was given a rest, the island monument in the living room reminded him.

Just as Dabai was about to get up, Xiao Yi held it down and said, "Let me do it. I'm here to do morning exercises too!" Dabai lay down again. Although it had been promoted to S level, it was holding the Xuanyuan Sword against it. Xiao Yi, it felt like it still couldn't defeat it.

And those sea creatures were too weak, so there was no need to worry about Xiao Yi's safety.

Xiao Yi took the Xuanyuan Sword, came to the manor, found the bloody BMW, and said, "Let me see how fast you are!"

Get on your horse!

"Drive!" Xiao Yi pulled the rein and shouted.

"Xi Lulu!" The Sweaty BMW yelled, and immediately rushed out, very fast!

Xiao Yi even felt that he couldn't see the scenery on both sides clearly!

You must know that Xiao Yi has an S-level physique now, and his physique has been improved in all aspects, including his visual capture ability.

Unexpectedly, the SSS-level hard-earned BMW is so fast that I can't see it clearly!

In just 20 seconds, Xiao Yi arrived at the target position, pulled out the Xuanyuan Sword in his hand, swung the sword, and the fish that was attacking the cornerstone was cut in half.

Xiao Yi picked up the two halves of fish to the shore with an iron gun. At this time, the shore was full of sea fish, which were caught by automatic fishing nets yesterday.

"Let Uncle An continue to handle the sea fish!" Xiao Yi muttered, and then rode back to the villa on his hard-earned BMW.

Seeing that the island tablet did not continue to remind that the island was under attack, Xiao Yi secretly said: "System, sign in!"

"Successful sign-in, get a reward: building upgrade card (S-level)."

"Building upgrade card (S-level): Any building below S-level can be upgraded to S-level."

Obtaining the upgrade card this time is limited to buildings, and cannot upgrade people, so Xiao Yi almost doesn't need to be too entangled, just decide which building to use it on!
Xiao Yi took out the building upgrade card from the system space!

"Hey, it's detected that you have a building upgrade card (S-level), please choose to use the target!"

"Digester!" Xiao Yi immediately replied.

The level of other buildings is not low, and there is no need for special upgrades at present!
Only this biogas digester is an ordinary biogas digester. After upgrading to S rank, they can use the biogas as soon as possible!

"Successfully used, the biogas digester has been upgraded to a biogas digester (S-level)."

Xiao Yi walked out of the villa and came to the biogas pool. The upgraded biogas pool has a more sci-fi style, and all the exposed parts are made of metal!
There is also a control room on the side, fully automatic control.

"Biogas digester (S level): It has been connected to the place where human and livestock manure is produced. The input of straw requires manpower, and the rest is fully automatic. The efficiency is 160% higher than that of ordinary biogas digesters, and it is safe and reliable!"

"It's much more convenient this way! At least you don't have to do the stirring work artificially!" Xiao Yi muttered.

After seeing the upgraded biogas digester, Xiao Yi walked back to the living room.

The island monument rang again, this time two sea creatures attacked at the same time!
Xiao Yi rode on the bloody BMW again. Instead of calling Jiang Yuntian, he went to one location by himself, and after killing the sea creature with one sword, he went to another location. It was still too late!
The highest level of attack of the sea creatures encountered so far is B level, so Xiao Yi can kill them all in seconds.

"With the bloody BMW, the speed is guaranteed!" Xiao Yi looked at the sweaty BMW under his seat, very satisfied.

At this time, Jiang Yuntian and the others had finished their morning exercises, and they each returned to their posts.

Xiao Yi returned to his island monument, wanting to see if there were any special changes in everyone's marine life attacks today.

Only then did Xiao Yi realize that Gudao Qiusheng had sent him a private message.

"Boss, I saw some natives coming towards me!"
