Next, Brother Tiannan continued to make some modifications to his brain-hole work, especially the lubrication of the most important gears and the 24-strand drive vine, which were repeatedly debugged.

Then, it was the official shipment, and in order to be able to integrate it more perfectly with the hull, the aft power compartment and the shape and construction of the vine engine needed to be modified again.

I was busy until the evening, taking a bath and eating, and in order to celebrate today's major success, Brother Tiannan had a good celebration with Xiaoxiao in the evening.

"Do you like it?" After parking, lying in his lover's arms and drawing circles on his chest, the snow-white skin looms, which makes people feel refreshed, such a pleasing scene, while feasting his eyes, Tian Tiannan will not treat his hands badly.

"Baby, you're getting more and more proficient... When can we get on the highway? "When he thinks of drag racing on the highway, Brother Tiannan has a dry mouth, and that kind of excitement can only be known to know what it feels like if he has experienced it.

"If you want to be beautiful, my mother told me that you can't spoil you men before you get married, otherwise with your current status and future development, people will soon fall out of favor and be abandoned!" Pouting, the young lady said unhappily.

"Where can I be? We are honest children, we will never do that, and our baby has nothing to say about the hardware facilities or software conditions, I really haven't met a woman who can compare to you! ”

"Hands... Bad... Still can't do it, Tiannan, on the wedding night, everyone depends on you..."

"Alright, let's walk around again..."

"Do you still have oil?" Raising his head and looking at Tian Tiannan, he smiled contemptuously.

"It's true that it's not as much as yours, but it's no problem to run another 180 kilometers!"

······

There was nothing to say all night, it seems that Brother Tiannan performed well today, and made a small exception to carry out a maintenance on his new car, which took a full three hours, although he was still not allowed to go to the highway, but many advanced maintenance items were not worse than the highway, which can be said to have really made Tian Tiannan feel comfortable once.

The next day, the official launching trial began, and Tian Tiannan personally completed all the commissioning of the ship and personally took charge of the engine control.

The first test is downstream, with a maximum speed test.

"Hahaha... Hehehe..."

Driven by maximum power, the experimental boat downstream was no slower than the speedboat in the previous life, and the bow of the boat, the crisp and beautiful laughter of the little lark came from time to time, and this test was definitely a happy experience for her who had never been on such a fast boat.

After driving nearly 20 kilometers, Tian Tiannan turned the bow of the ship with a big detour and began to test the anti-current navigation, and as soon as he came up, under strong resistance, he had to drive to the third speed, that is, at the same time with 18 strands of drive.

Fortunately, whether it is the hull or the engine, it is catalyzed by the sacrificial power, and in the words of the system, the durability is leveraged.

But at the same time, under the high speed, the consumption of sacrificial power was far beyond Tian Tiannan's previous estimate, and in just twenty kilometers of distance, most of the vat of sacrificial points he prepared was actually consumed.

"Tut-tut... This is only in the state of an almost empty ship, if there are more people in the future twenty or thirty kilometers, it will cost 1,000 sacrificial points, it seems that the first generation of products is always accompanied by a lot of drawbacks! Because of the existence of the system wooden box, Tian Tiannan is not worried about using it on a cargo ship, but if it is used to transport people, this consumption is not small.

After some experiments, Tian Tiannan had some ideas for improvement in his heart, mainly about the hull, since he wanted to think about things, he naturally needed to be quiet, so he got off the boat, handed the boat to Xiaoxiao to toss, and sat alone on the shore and began to ponder.

Just thinking about it was not enough, and with the soil under his feet, he began to draw with a branch.

"Boom"

Drawing and drawing, suddenly, there was a loud noise from the boundary river, Tian Tiannan hurriedly looked up, and saw some black shadows around the experimental ship, which seemed to be attacking the experimental ship.

"Quick, get the No. 2 experimental ship out!" Seeing this, Tian Tiannan immediately got up and roared angrily, asking the ship's attendant to take out the spare experimental boat and immediately go into the water to rescue.

Because it was a countercurrent, as soon as he came up, Tian Tiannan ordered to turn on all his horsepower, and when he rushed closer, he finally saw the true face of those black shadows.

"It's... Merman? "Except for some fish scales on the upper body, it doesn't look much different from the Terrans, but the underwater part can clearly see a large fish tail fluttering.

"This Nima is a little ugly... Sure enough, there's no such thing as a mermaid! "Not only are there no mermaids, these mermaids look like males, with burly bodies and sharp steel forks, but they look like guys from the East China Sea.

In the river, it is more effective to deal with them with ice and aquatic plants, a series of ice blades and ice guns shoot over, as long as these guys are frozen, they will immediately use the steel forks in their hands to break the surrounding ice, and immediately dive.

But in this way, the aquatic plants that have grown up from the river and have been catalyzed by Tian Tiannan will immediately find them, wrap them inside and outside like dumplings, and then be thrown onto the deck of the ship one by one.

A total of more than a dozen mermaids were all captured alive, and they were taken back to the port, Tian Tiannan ordered people to find the most well-informed source wolf around him, and began to interrogate these mermaids who attacked them.

"Say! Why attack us? Recruit you, mess with you! "People don't offend me, I don't offend people, just came to this respectful realm, Tian Tiannan has already restrained his character of liking to do things, but he didn't expect someone to bully him, he naturally can't have a good mood.

"Terran, the boundary river is our homeland, and you entered without permission, and you still say that you didn't provoke us?" Who knows, a guy who seems to be the leader on the other side is even more excited than Brother Tiannan, and yelled.

"Your homeland? Lao Bai, what's the situation? "Brother Tiannan has been rectified, is there actually a master of the boundary river?

"Master, don't listen to these mermaids, the boundary river has never belonged to anyone, but because they are water tribes and have lived in the boundary river for generations, no foreign race is allowed to step into the boundary river and forcibly occupy the boundary river." With a look of disdain, the source wolf, who was caressed in Xiaoxiao's arms, spoke.

"That's why the shipbuilding industry here is so backward?" Tian Tiannan understood, in fact, it stands to reason that as the overlord of the water, the ability to occupy this boundary river is also in line with the laws of this world.

But the bad thing is that now he needs to develop the waterway through the boundary river, so he is bound to conflict with the other party, although he doesn't want to cause trouble, but if the waterway can't be developed, his development plan will be stillborn, obviously, this beam must be concluded!
