After ou shaotian talked about the matter in the group chat, he ignored it and continued to study the true meaning of water while there was still some time in the afternoon.

On the other hand, yunduo'er and yaoxingyu are also on the garrison mission together.

Now yunduo'er, yaoxingyu and Longxue have become three sisters. They often fight side by side and make progress together.

Wu aoyi and others are also here. Their task is to garrison the residential island.

In the evening, just after eating the dinner from the island residents and preparing to practice, an accident happened. A third-class Octopus came ashore.

"Gentlemen, there is a giant octopus monster in the harbor. It has three levels of intermediate strength. Please help as soon as possible!"

An island guard rushed to know.

"Well, we know!"

Cloud son nodded, and then called on the shake Xingyu and others, toward the port away.

In the harbor, the huge octopus monster is rampant, and the harbor's escort is encircling and killing, but it is far from the opponent.

The island is not big, the population is less than 10000, and there are not many experts. The strongest guard is only the strength of diaoyong.

"Get out of the way!"

After arriving, yunduo'er let out a soft drink, and Yin Yang double swords shot out to kill the giant octopus.

Although the size of the octopus is not high, its size is very huge, with its tentacles supporting the ground. It is 20 or 30 meters high.

For ordinary small fishing villages, every occurrence is a disaster.

Wu aoyi and others soon joined the battle, and all of them had their unique skills. One by one, they broke out the fighting power of the big fishing sect.

Yunduo'er's Yin and Yang double swords are in one, and the strongest blow breaks through the huge head of the octopus monster.

The dragon snow that followed was also not simple. The sword Qi of more than ten meters bombarded the huge wound and did not let it heal.

Wu aoyi and others attack those tentacles and cut off one tentacle with one move.

More than ten people killed the octopus monster in a round of attack.

They are already familiar with this kind of fighting. Obviously, they are not

As time goes by, yunduo'er and others spend every day cleaning up the large aquarium on the island.

In order to catch up with Ou shaotian, they work very hard every day. Apart from patrolling, most of the time they focus on cultivation.

The most important thing to do every day is to practice with each other.

The villagers are mainly responsible for the food. They don't need to do anything about it. As for the food, it's mainly the Shui people they killed.

So the strength of yunduo'er and others has also improved by leaps and bounds during this period of time when they are stationed on the island!

……

At the twelve Star Academy, ou shaotian, who is practicing, has received a message from Zhang pengpeng that the upgrade materials for the fishing boat separation have been collected.

There is no shortage of millennial cold iron and dark iron.

In the world of fishhatch door, there are several damaged large flying boats. These flying boats are upgraded materials, with a large number of Millennium cold iron and black iron.

It's just the lack of xuanjinshi.

"Shaotian, this is the material you asked me to collect!"

After meeting, Zhang pengpeng gave a space equipment to ou shaotian.

He wanted to send it in person, but unfortunately, he was not a student of the twelve Star College, so he could not enter the twelve Star College at all.

"Yes, I'll go back first. I'll contact you whenever I have something to do!"

Ou shaotian took the materials and left.

After returning to the college in a hurry, he upgraded the fishing boat separation for the first time, but this upgrade was extraordinary.

In the dormitory, ou shaotian opened the courtyard array, and then began to upgrade.

With his command, the tattoo mark on the back of his hand began to shine, and the faint light began to spread from the mark, and soon covered his whole body.

About half an hour later, the light disappeared.

This upgrade took three times as long as he had expected.

Obviously, this upgrade is extraordinary.

Separation: Xuanjin Lingzhou

Grade: primary

Speed: 120msArmor: mainly made of cold iron, covered with dark gold, it's hard to hurt Dazun

Main gun: large air gun, compressed air attack, effective range of 10000 meters, every three seconds compressed an air bomb

Auxiliary gun: medium air gun, distributed on both sides of the ship, with five doors on each side

Radar: scan and deduce, detect all kinds of information, Consume aura to deduce skill

Fish Cabin: Door world

Appendage: it can be changed into imprint and attached to noumenon

Diving: sailing on the bottom of the sea with constant speed

Appearance: the captain is 100 meters, the width is 20 meters, the bottom is 30 cm thick, covering Xuanjin, the thickness is 3 cm, the top and bottom are four layers, the front is 10 meters long Xuanjin collision angle, and the hull is full of mysterious lines, It looks very mysterious

Upgrade: it needs ten tons of Millennium cold iron, five tons of xuanjinshi, three tons of xuantie and one ton of xuanlingmu

This time, the upgrade has changed a lot.

Before the upgrade, it was already the top cold iron flying boat. After the upgrade, the name really became Xuanjin Lingzhou, which was obviously stronger.

Xuanjin completed the coverage, so that the fishing boat has a super defense, even if it is a big fishing Zun level attack, it is difficult to destroy.

The speed on the sea remains the same, but the speed on the bottom of the sea remains the same.

In this way, the combat effectiveness of fishing boats on the seabed will be greatly increased, and it will be easier to plunder resources on the seabed than before.

"That's great. Originally, the speed of submarine stealth had to be reduced a lot, but now it can maintain the original speed."

Ou shaotian is a little excited.

Obviously, the lines on the fishing boats are more powerful, and they can ignore the resistance of the sea. Otherwise, it is impossible to keep the speed unchanged.

Under normal circumstances, the resistance of sea water increases and the speed will slow down when the sea bottom is diving.

"Well, something's wrong!"

Suddenly, ou shaotian found something wrong.

For the separate control of the fishing boat, he felt a little lagging behind, not as smooth as before.

"I'll go. Won't there be any problems?"

Ou shaotian was a little flustered.

You know, the separation of fishing boats is his greatest reliance. If there is a problem with the separation of fishing boats, then he is really finished
