"Anyway, I'm responsible for this, so I have to take it!"

"You ......"

Qin Haiyan wanted to say something, but at this time Chen Nai spoke.

"Let him help, if he doesn't help, then he won't be Hein, this guy who adheres to the spirit of chivalry is very troublesome."

Hine understands this person, Chen Nai, although he is very sunny and gentle on the surface, and seems to be a warm man who is very good at talking.

But if you really think so, then you're wrong, Hein is not a warm man.

During the three years of being cursed, he has been tormented by pain and endured the contemptuous gaze of others, although Hine has not fallen because of this, but his sunny and gentle heart has added some dark side.

So sometimes Hine speaks mercilessly, even a little viciously, and black-bellied.

But his principles have always been there, and he has never changed, insisting on abiding by the spirit of chivalry, which is the bottom line of Hine.

"I see, then I'll trouble you to help!"

"Well, since you have decided to go to the Forbidden Island, and then go to the deep sea by the way, you have to be well prepared."

Chen Nai made a formal decision to extend the journey, there will be stone monuments on the island, and it is estimated that there will be a lot of deep sea.

In terms of area, the ocean is several times the size of the continent, so the stone tablets sealed in the ocean are probably several times larger!

If you go along the way, there may be some windfalls, but it's not a bad thing anyway.

It is necessary to prepare for a long-term battle, and this preparation naturally has to be more sufficient, so Chen Nai has his own plans.

"I've decided, I'm going to forge a ship."

"Master Cat, you can still build a ship!"

"Of course, I will have a lot of things, and there will be opportunities for you to see them in the future."

"I don't think there's any need for shipbuilding, my father has prepared the best ships for us, and if we want to build ships, ......"

Qin Haiyan originally wanted to say that this shipbuilding would take a lot of time, but when he thought of Chen Nai's one-click forging and the forging skills shipped in one second, he didn't continue.

For Chen Nai, as long as there is a forging diagram and sufficient raw materials, the forging process is completely unnecessary.

And designing a forging diagram, with the current ability of Add and the goblins, if the thinking is complete and clear, it can be easily done in one night.

"I didn't underestimate you, the level of ships in the Duchy of Babylonia, but those ships of yours are basically cargo ships for trade, and they can be transported, but if you want to dive into the sea, it will not be enough at all."

"What's more, if our purpose is to find out the news and save people, then we can't take the route of trade, we have to act on the fly, and the route we have to take when the time comes, it is estimated that we will encounter a lot of deep-sea monsters, and we must have the ability to fight, even if we don't have it, at least we must be able to escape, and we can't be entangled by them."

"So what kind of ship are you going to forge forge?"

"Submarine!"

When it comes to vehicles that can move in the sea, Chen Nai is like a submarine for the first time, and on the earth, the development of submarines is very mature.

There are many kinds and different shapes, ranging from small civilian submersible detectors that are fully automatic or operated by one or two people and operate for several hours, to nuclear submarines that can carry hundreds of people and continue to dive for 3-6 months.

Territorial waters. Territory and airspace are the domain of a country and are inviolable, and if a war is waged from the sea, it will be difficult to ensure concealment, which is why such a thing as a submarine has been developed.

A fully automatic submarine carrying a few warheads launched directly, if it is not detected or intercepted, it is really enough to eat a pot.

At the level of modern science and technology, the problem of water pressure restricts the continued development of submarines, and when it goes deep into the sea thousands of meters, the water pressure is so strong that it is terrifying, and when it reaches a certain limit, even if it is a steel can, it will be crushed into thin sheets by water pressure.

Although the material of the submarine can withstand high pressure, it is not without limits.

And in this magical world, water pressure can be solved by means of magic, so the Grand Duke and their merchant ships can also dive into the sea tribe city 10,000 meters below the sea.

But the process of diving down is very slow, and it takes a full three days to complete the process of diving.

However, if you use a submarine, the speed of the dive is absolutely fast, and the speed of sailing is faster than that of a merchant ship.

Whether it's to snatch the stele or save people, you have to be fast.

After understanding the concept of the submarine, Qin Haiyan raised his hands to support Chen Nai in forging the submarine.

"Master Cat, how long will it take for this submarine to be built?"

"Two or three days, I'll have to go back and talk to Eddie and the dwarves."

"Understood, Master Cat, you just put forward a concept and idea, and how to improve it depends on Eddie and them."

For Chen Nai's behavior of throwing off the shopkeeper, Qin Haiyan and others are really familiar with it, and they have long been accustomed to it.

"Hey, I'm ...... Forget it, I won't tell you, just hurry up and get things out. ”

Chen Nai originally wanted to say that it was so easy for this technology side to transition to the magic side.

But if you think about it carefully, you really don't know and study submarines, and you really just put forward a concept, idea and framework, and it is indeed up to professionals like Eddie and the dwarves to fill in the content and improve these things.

Before going to the underground factory to tinker with the submarine, Chen Nai remembered something and asked Hine to do it.

"While there's still some time, there's something to trouble you to do."

"Master Cat, what did you say?"

"I will go to the Holy See to report to the Holy Maiden and your master, and our next trip will also investigate Emma's life experience. Emma had previously been a pastor in the Holy See, and was later placed as a missionary, as evidenced by the Holy See's letters. ”

"Yes, I'll do it!"

Chen Nai gave the letter Emma had on her back to Hine at the beginning, and with this letter, it shouldn't be difficult to investigate.

What's more, it is still the matter explained by the Holy Son and the divine envoy, and it will definitely be done all the way with the green light, but what I didn't expect was that when Chen Nai was in the underground factory, it took nearly two days to get the design of the submarine ready, and by the way, the finished product was forged, Emma's life history had not been investigated.

actually only got information that his mother was unknown and his father was unknown, which made Chen Nai's temper come up.

Check, keep checking for me!

I don't believe it, Emma really jumped out of the rock.
