"Exactly?" Look at this side Mike. Colt's expression, Li Huailin always felt a little bad feeling, it seemed that he said the same thing last time and then he was thrown to the far north, and then this time again? Li Huailin suddenly felt that he was looking for this guy unreliable.

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

"So MD: Was that thing really a test item last time?" Li Huailin couldn't help but say.

"My lord, spare my life, although that thing is a test object, but it has also been perfectly theoretically demonstrated, and there is only a little accident...... Colt also realized that he had leaked his mouth and quickly made up for it.

"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, and he was nervous, "It's really not a test product this time, right?" ”

"Absolutely, I've already let my brother use it." Colt here said immediately.

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

"No, it's another one, the one before hasn't healed because of psychological trauma, and now he's gone back to his hometown to farm." Colt said with a smile.

Li Huailin: "......"

"Lord Duke, it's not because of my problem, the last time I had a problem with my lava diving suit, it was obviously my stupid brother who miscalculated the time of going back and forth, resulting in insufficient fuel to be trapped in that kind of place, it's definitely not my tool's problem, you have to believe me." Colt looked at Li Huailin's skeptical expression and immediately said.

"Okay, okay, don't explain, hurry up and show me the dry goods first?" Li Huailin is also messing around with this matter, isn't it just a submarine? Even if it explodes, can you still blow yourself up? And even if you explode under the water, you can't drown yourself, so you really don't have anything to fear...... Probably.

"Of course, always ready." Colt immediately became excited when he heard this, and then immediately took Li Huailin to the backyard. Yes, it was the laboratory that I took Li Huailin to last time, it was still the same place, the same taste, and it was a mess when I went in, and there was no change at all.

Walking to the inside of the laboratory, Li Huailin saw the portal that threw him to the distant north last time, and Colt who saw Li Huailin's eyes was also a little embarrassed, and he was also worried that Li Huailin would settle accounts with him when he saw this thing, so he quickly took a piece of cloth next to him and covered this thing.

"I'll tell you, if something goes wrong again this time, I'll let you go up and teleport it." Li Huailin pointed to the teleporter here and said.

"Oh, of course, I'm confident this time." Colt didn't know if he was really confident, anyway, he just played a package ticket.

Then Li Huailin saw the thing that the other party packed the ticket - a huge safe. Li Huailin didn't react at first, then confirmed, and looked at it carefully, yes, no matter how you look at it, it's a safe.

"Lord Duke, this is my most satisfying work, the Seluco-3, which is designed for underwater operations...... Wait, Lord Duke, where are you taking me? Before Colt could finish his words, Li Huailin directly pulled him in the direction of the teleportation array next to him.

"No, Lord Duke, I'm not kidding, don't look at the exterior light of this thing......"

"What does it mean that the appearance is not good, this TN is a safe, okay? Is the safe good? Li Huailin shouted directly.

"No, my lord, this is not a safe, this is Seluco-3, can you see that this is completely different?" Colt was a little excited when he said this.

"You tell me that this doesn't look like a safe, you look at the square shape, you look at this steel plate, and isn't there a combination lock in front of it? What do you say is not like that? Li Huailin couldn't help but say, yes, this thing in front of him is really the shape of a completely copied safe, and even the combination lock on it is there, "Don't tell me if you TN, let me stay in this thing and go into the water." ”

"This ...... When you say that, Lord Duke, I really think it's a bit like a safe. Colt suddenly looked at his work and said, as if he had just known it.

"......" Li Huailin looked directly at Colt and didn't speak.

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

"Really?" Li Huailin simply watched him pull it.

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

"And then, you didn't even think about coming up, did you?" Li Huailin asked.

"You see that there is a buoyancy magic array at the bottom of the machine, once it wants to float, it can be floated directly by starting, but the current technology can only float once, and the second time you have to charge the magic circle again." Colt said immediately.

"Oh?" Li Huailin really didn't think that this thing could really float up, and looked at the bottom of this thing, there were indeed some patterns (this thing is hanging now. ）

"Lord Duke, you see, this machine also has its own metal detector, which can detect metal within a range of 500 yards, as long as there is metal around, this machine can find it, this is a custom function for underwater treasure hunting." Colt saw that Li Huailin seemed to be listening a little, and hurriedly introduced it again.

"Oh, so what is the accuracy of this metal detector, can you find metal the size of a bracelet?" Li Huailin asked.

"This ...... I guess so. Colt thought for a moment and said.

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

"Uh...... Surely, Lord Duke. Colt immediately changed his tune.

"Are you really sure this thing works? You know, I haven't seen a window or anything like that, so how do you look outside when you go in? Li Huailin asked.

"Oh, don't look outside." Colt on this side waved his hand directly, "I've tried, and any transparent material can't resist the pressure under the water, so there's no way, you really can't observe the outside." ”

"......" Li Huailin raised his forehead, and also knew that this might be because the productivity level in the game was not enough, and he couldn't produce things like tempered glass, "Then how can I drive this thing, can I just control the direction in it and let it fly around?" ”

"Please rest assured, Lord Duke." Speaking of this, Colt became excited again, "After many experiments, I have turned this thing into a fully automatic prop, it can automatically search for surrounding metal, and then advance in the direction of the metal, and then when it is pushed nearby, this thing can absorb the things below." Look, adult, under this machine is a storage device, which can store about 100 cubic meters of things (similar to the kind of storage ring), so just suck everything back at once, and then slowly sort it, and if there is no metal around, it will automatically go forward, such a design, what do you think? ”

"Your design is real and reasonable......," Li Huailin raised his forehead, "Then may I ask why people need to go in since it is fully automatic?" Wouldn't it be over just throwing it into the water and letting it find something on its own? ”

"I'm sorry sir, but this thing is said to search for things automatically, but the energy consumption itself is too great, and the automatic fuel refueling device is a bit complicated, so people have to ......refill it at any time," Colt said.

"TND, are you mistaken, searching for things is so smart, and then adding fuel has to be manual, you just say that I shovel coal in it, right?" Li Huailin supported his forehead.

"Lord Duke, the fuel we use is spotted concentrate......"

"Okay, okay, I'll care what you burn." Li Huailin said that he had a headache, "Anyway, tell me how to operate first......

"Your Excellency agreed to try?" Colt here asked happily.

"I ask you if there's anything more reliable?" Li Huailin asked.

"It's state-of-the-art." Colt said immediately.

"So you say 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 is very simple, that is, to throw fuel into something that seems to be a boiler, and then it is said that you can suck it up without caring about anything. Then Colt emphatically warned Li Huailin about the precautions, first of all, this machine can work underwater for about an hour, and then there will be no fuel, so Li Huailin is optimistic about the time to start the floating device.

"Second, you can't add more fuel to this fuel, otherwise it will explode." Colt said, "But it can't be less, because if the boiler is in an empty state for a long time, the water vapor in it will be left and evaporated, then it can't be started, and once it is started again, it will still explode immediately." ”

"......" Li Huailin stared directly at Colt and didn't speak.

"But don't worry, my lord, as long as you add as much fuel as I said, it will definitely not explode...... Probably ......"

"Why do you have to add a rough idea at the end, how unsure are you, what a good guarantee? This TN explodes at every turn, can you really play? Li Huailin couldn't help but say.

"No problem." Colt changed his words again, "Please rest assured, don't worry, don't worry......"

Although he was very hesitant, Li Huailin finally agreed, thinking that no matter what, this thing would try it first, and the worst result would be an explosion, as if he was not very afraid...... set up a FLAG for himself, and Li Huailin nodded in agreement. (To be continued.) )
