"Just?" Looking at Mike Colt's expression here, Li Huailin always felt a little bad. Last time, he said that, and then he was thrown to the far north. Then this time he came again? Li Huailin suddenly felt that it was reliable to find this guy.

"Yes, Duke." Colt seemed to see Li Huailin's suspicious expression, "Please rest assured, I will definitely not take out any props in the test for you to use this time.

"So that thing last time md was indeed a test item?" Li Huailin couldn't help but say.

"Sir, please spare me. Although that thing is a test item, it has been proved perfectly by theory. There was only a small accident..." Colt also realized that he had let it go and quickly made up.

"Okay, okay, it's over, I'm too lazy to bother with you." Li Huailin also waved his hand. The shadow left last time was too deep, which made him nervous. "This time it's really not a test item, right?"

"Absolutely, I have already used it by my brother." Colt said immediately.

"Your brother? Is the one I didn't see last time?" Li Huailin asked.

"No, it's another one. The one who used to have not healed due to psychological trauma, now she has gone back to her hometown to farm." Colt said with a smile.

Li Huailin: “…”

"Dude is not because of my problem. The last time there was a problem with my lava diving suit, it was obviously my stupid brother who miscalculated the round trip time, which caused insufficient fuel to be trapped in that kind of place. It is definitely not a problem with my tools. You have to believe me." Colt said immediately when he saw Li Huailin's suspicious expression.

"Okay, okay, don't explain, hurry up and show me the real stuff?" Li Huailin was also indifferent to this matter. Isn't it just a submarine? Even if it explodes directly, it can still kill himself? Then even if it explodes under the water, it can't drown himself. Then there's nothing scary about him...probably.

"Of course, be ready at any time." Colt was immediately excited when he heard this, and immediately took Li Huailin to the backyard. Yes, it was the laboratory I took Li Huailin to the same place and the same smell. It was a mess when I entered, and there was no change at all.

When he walked into the laboratory, Li Huailin saw the portal that threw him to the distant northern country last time. Colt, who saw Li Huailin's eyes, was a little embarrassed, and was also worried that Li Huailin would settle the score with him when he saw this thing, so he quickly took a piece of cloth and covered the thing.

"I tell you that if there is another problem with the thing this time, I will ask you to go up and teleport it." Li Huailin said, pointing to the teleporter here.

"Oh, of course it's okay. I'm very confident this time." Colt didn't know if he was really confident, he just made a promise.

Then Li Huailin saw the thing that the other party had packed, a huge safe. Li Huailin didn't react at first, then confirmed it again, and looked carefully. Yes, no matter how you look at it, they are all safes.

"Duke, this is my most satisfying work. The Seluke-3 type is specially used for underwater operations... Wait, where are you taking me with you?" Before Colt finished speaking, Li Huailin pulled him directly to the teleportation array next to him.

"No, Lord Duke, I'm not kidding, don't look at the fact that the outer light of this thing is not very good..."

"What does it mean to look bad? Is this tn's safe? Is the safe good?" Li Huailin shouted directly.

"No, sir, this is not a safe, this is a Seluco-3 type. Can you see, this is completely different?" Colt felt a little excited when he said this.

"You told me where this is not like a safe. You look at the shape of Sifang. You are looking at this steel plate. Isn't there a password lock in front of it? You said where this is not like?" Li Huailin couldn't help but say, yes, the thing in front of me is really the shape of a completely copied safe, and even the password lock on it is there, "Don't tell me to let me stay in this thing."

"This... I really feel like a safe when you say this." Colt suddenly looked at his work and said, as if he had known it just now.

"..." Li Huailin looked directly at Colt without saying anything.

"But...but, although it looks similar, I can guarantee that its function is still the function of underwater operation, and it is definitely not a safe!" Colt said immediately.

"Is that true?" Li Huailin simply saw him twitching.

"Yes, Lord Duke, look at this machine, it's all made of iron, it's very heavy and it's very fast to get into the water." Colt pointed to the box and said.

"Then, I never thought about it coming up, right?" Li Huailin asked.

"You see, there is a buoyant magic array at the bottom of the machine. Once it is about to float, it can be floated directly by activating it. However, the current technology can only be floated once. If it is the second time, the magic array must be charged again." Colt said immediately.

"Oh?" Li Huailin had never thought that this thing could really float up. After looking at the bottom of the thing, there were indeed some patterns (this thing is hanging now.)

"Duke, look, this machine also comes with a metal detector, which can detect metals within a range of 500 yards. As long as there is metal around, this machine can be found. This is a custom-made function specially designed to find treasures underwater." Colt seemed to have heard Li Huailin a little, and quickly introduced it.

"Oh, what is the accuracy of this metal detector? Can you find bracelet-sized metal?" Li Huailin asked.

"This... should be OK." Colt thought for a while and said.

"Why are you so unsure?" Li Huailin asked immediately.

"Uh... it's certainly OK, don't worry, Lord Duke." Colt immediately changed his words.

"Are you really sure this thing can be used? You have to know that I haven't seen windows or anything like this thing yet. How do you observe the outside after entering?" Li Huailin asked.

"Oh, don't have to observe the outside." Colt on this side waved his hand directly, "I tried it. No transparent material can resist the pressure underwater, so there is no way, and I really can't observe the outside."

"..." Li Huailin held his forehead and knew that this might be because the productivity level in the game was not enough and he could not produce tempered glass. "Then how to drive this thing, can I just control the direction inside and let it fly randomly?"

"Please rest assured, Lord Duke." Colt was excited again when he said this. "After many experiments, I have turned this thing into a fully automatic prop. It can automatically search the surrounding metals, then push them in the direction of the metal, and then when it is pushed nearby, the thing can absorb the things below. Please see, the machine is a storage device, which can store about 100 cubic meters of things (similar to the storage ring), so just suck everything back at once and then slowly sort it out. If there is no metal around it, it will automatically move forward. What do you think of this design?"

"Your design is real and reasonable..." Li Huailin held his forehead, "So why do you still need people to go in since it is fully automatic? Isn't it just thrown it into the water and let it find something by itself?"

"Sorry, although this thing is automatically searched for things, its energy consumption is too great. However, the device for automatically adding fuel is a bit complicated, so people must add fuel at any time..." Colt said.

"Tnd, are you mistaken? Searching for things is so smart, and adding fuel needs to be manually added. Just say I just shovel coal in it, right?" Li Huailin held his forehead.

"Dude, the fuel we use is spot concentrate..."

"Okay, okay, I care what you are burning." Li Huailin put his forehead on and said that he had a headache, "Anyway, tell me how to do it..."

"Sir, have you agreed to try?" Colt asked happily here.

"I'll ask you if you have anything more reliable?" Li Huailin asked.

"This is the most advanced," Colt said immediately.

"So do you think I have a choice?" Li Huailin could only nod.

So Colt here immediately instructed Li Huailin how to operate this thing. Of course, the operation was very simple. It was to throw fuel into something that looked like a boiler, and then it was said that it could suck the thing up without any care. Then Colt emphasized to Li Huailin what to pay attention to. First of all, this machine could operate underwater for about an hour, and then there was no fuel. Li Huailin was optimistic about the time to start the floating device.

"Second, this fuel cannot be added too much, otherwise it will explode," Colt said. "But it cannot be added too little, because if the boiler is in an empty state for a long time, the water vapor inside will be evaporated and evaporated dry, then it cannot be started. Once it is started again, it will explode immediately."

"..." Li Huailin stared at Colt without saying a word.

"But please don't worry, as long as you add fuel according to the quantity I said, it will never explode...probably..."

"Why do you need to add a rough one in the end? How uncertain are you? What's the promise? This TN always explodes, can it really play?" Li Huailin couldn't help but say.

"It's definitely okay." Colt changed his words again, "Please rest assured, don't worry..."
