The underwater speed of the submarine, which is said to be the fastest Maoguo A-class boat, can reach 42 knots. (1 knot = 1.852 km/h)

Gu Yu didn't know this data, he just felt that the magic boat was running very fast, from Baicheng Shunhe to the east, to the mouth of the Caohe River to join the Danjiang River, and then to Dongyun City, it didn't seem to take much time.

Not only is it fast, but it also moves very freely, it can be long or short, large or small, and it can pass through any waterway.

The magic boat has room for refining the small Qiankun technique, and it is also supplemented by the small five elements technique, which has a certain protection and attack power. If it is used in the military, it will be directly under the feet of the torch goddess, and the gringos will not be able to find it.

Even so, Gu Yu was still not satisfied. According to his concept, it is to refine a "machine" that uses spirit stones as an energy source, rather than a "magic weapon" supported by his own mana.

The difference between one word and the difference is very different.

The former can be manipulated only by innocence, and it consumes spirit stones, and the latter is a portable treasure that cannot be used by others.

"Gurgle!"

"Gurgle!"

At the mouth of the Bohai Sea, the current suddenly accelerated, as if something transparent swam in, pushing away layers of waves. Immediately after, the transparent color gradually becomes solid, and it quickly dives.

"Whoa!"

The water splashed down, and a strange white bone shuttle floated on the surface of the sea. Surrounded by land on three sides, facing the sea on one side, I don't know what kind of remote place it is, there are no people, only two warships cruising in the distance.

"This is, the border at sea?"

Gu Yuhu looked around suspiciously, the warship was hung with the flag of the Xia Kingdom, unhurried, but the opposite side was empty, dead and silent.

"It seems that there are three Jin families over there, the country is weak, the navy is weak, and even their own sea areas have been abandoned. ”

Eh, there is no doubt about it! The Jin Sanjia does have a navy, although it does not have a strong sense of existence, but it is still more reliable than Mongolia's Seven Martial Seas.

He observed the position, continued to dive, skipped the patrol ship and headed south, heading straight for the Yellow Sea.

When there was no shore in front of him, rippling like a mountain, showing a majestic and magnificent landscape, he jumped out of the shuttle boat, lay down on it, and drifted along the current.

No way, in essence, Lao Gu is a literary and artistic immortal.

"Gurgle!"

He squinted, his long eyelashes obscuring a little of the daylight, and the waves crashed against the shuttle, making a dense and unpleasant sound. The wind carries a unique salty (anti-harmony) wet taste, which is neither cold nor warm, nor disturbing.

It's pretty safe here.

In the past two years, due to the continuous upgrading and reproduction of alien beasts, trade between countries has been greatly hindered. Especially by shipping, a big country can ensure the stability of the port, but it cannot always send warships to escort it at any time.

At most, several countries have joined forces to clear some shipping lanes for transportation. Therefore, the current sea and air transportation, transportation speed and danger, all kinds of crazy tragedy in direct proportion.

"Bang!"

A strange hairtail fish with a sharp beak flew up, and it didn't have long eyes to stab a certain guy, but its body was still in the air, and it shattered into scum.

The flesh and blood were scattered on the surface of the sea, and the fishy smell drifted away, attracting a few more predators, Miamiamia finished grabbing it, glanced at the man, and turned over and dived to the bottom.

"Floating on the sea, you will unconsciously relax and find a small island to build a piece of land...... Huh?"

Gu Yu blinked, and suddenly remembered something.

At the end of the Tang Dynasty, it is recorded in the classic book "Records of the Famous Mountains of the Cave Heaven Blessed Land" that there are ten major caves, thirty-six small caves, twenty-four rules, seventy-two blessed lands, thirty-six Jinglu, ten continents and three islands, five mountains of the two worlds of immortal land and the mountains of the gods.

This set of names is a relatively complete construction of a set of cave heaven and earth spectrum, but it misses a very important space - water.

Later, in the Song Dynasty, King Quanzhen wrote "Xiyue Huashan Chronicles", which quoted a passage: "There are eighteen water mansions in the world, and Huashan Chebox Pond is the seventh water mansion." ”

This sentence comes from "The Story of the Water House", which is a very systematic introduction to the waters of all parties. But it's a pity that "The Story of Water Mansion" has long been lost, and no one knows what the Eighteen Water Mansion is.

Gu Yu now knew that the Cave Heaven Blessed Land was the space opened up by the Earth Immortals. The so-called water mansion, erasing the mythological color inside, should be the same as the nature of the cave heaven blessed land.

He couldn't help but think of this, of course, not to open up the Water Mansion, but to follow the introduction of the Water Mansion, and remember a very famous immortal, An Qisheng.

An Qisheng, a native of Langya County, is a bigwig-level figure among the Qi magistrates, and his sense of existence has been brushed from the pre-Qin period to the Eastern Jin Dynasty. Even Li Bai wrote a poem:

"I used to be in the East China Sea, and Laoshan dined Zixia. I saw An Qigong in person, and the dates were as big as melons. ”

Of course, Li Bai is definitely bragging, but it also indirectly confirms this person's influence.

The immortals of the Xia Kingdom have little to do with the sea, and An Qisheng is the most famous one. It is said that he lived on an island, and the Qin Emperor and Han Wudu sent people to ask for an elixir, but they found nothing, so they could only build Sendai one after another.

An Qisheng's master was Heshang Gong, and he was also a big man, how big was it? He wrote a commentary on the Tao Te Ching.

Gu Yu had already arrived at sea, so he simply went to look for it.

He just wanted to urge the magic boat, but his movements suddenly paused, and then he took out a communication talisman and flew away with a swish. After waiting for a stick of incense, he grabbed the void and caught a yellow talisman.

"Putuo, come and pick me up!"

…………

Zhoushan, Lotus Ocean.

On the calm and waveless water, there were suddenly waves in circles, and the air fluctuated, revealing a narrow white bone boat.

Gu Yu stood on it, raised his eyes and looked into the distance, and saw a figure sitting on the edge of a cliff on Putuo Island.

"Oh, you come down!" he shouted.

"You come up!" Xiao Zhai smiled.

"What did I do when I went up, I thought you were going to sit on the head of Sister Guanyin and wait for me. ”

"It's too ugly!"

“……”

Gu Yu was defeated in seconds, glanced at the super tall statue, and said helplessly: "Do we have to shout and talk like this?"

"Haha!"

Xiao Zhai laughed, his body flickered, and disappeared from the edge of the cliff.

In the next second, Gu Yu's pupils suddenly contracted, and the figure was empty, and it actually turned into a purple thunderbolt, and it took less than a breath......

Brush!

The thunder dissipated, and she had already arrived at her, and then took a step forward and said with a smile: "How is it?"

"It was so far just now, and now it's so close, will it be a negative number in a while?"

Gu Yu took two steps back and said strangely: "You have come up with a new idea?"

"It's not a matter of pondering, the system of the Great Lei Lang Jade Book is more complete than your Qi Eating Method, this trick can be cultivated, but I have weakened it a little, not a complete version. ”

"Oh, so you're a good person?"

"I'm not sure, but I think it's time, so I'll go back to the mountain and retreat. ”

Get!

Lao Gu was speechless, he really regarded his home as a hotel, he shook his head, waved his sleeves, and led the other party into the shuttle.

"This thing is good, there is enough space, and the concealment is good, but unfortunately it can't fly. ”

Xiao Zhaizi looked around carefully and was quite admired.

"Jiao himself can't fly, how can a magic weapon made of Jiao bones fly...... Hey, it sounds like we're down together for the first time...... Water ......"

He paused, because he clearly caught a trace of heat in the other party's eyes, and couldn't help but have a headache: "You just come when you say this emotion?"

"No, no, I'm just going to see how long your negative numbers are. ”
