The next day, Li Rujin got up early, and after a while, Dashuai and Wang Jianzhong also rushed over, had breakfast together, walked together, and walked to the emperor's palace together.

Everyone laughed while walking, and they all said that today is a good time to watch the sunrise, but this time, they have to go to the emperor's palace, and they will lose a lot. Along the way, the guard was heavily guarded, three steps and a post, five steps and a sentry, and when he arrived at the palace, the emperor had already gotten up, but the prince was still asleep, and Li Rujin did not see his younger brother Li Ruhu.

The emperor saw Li Rujin's probing of his brain, and said with a smile: "Li Ruhu was also in the palace last night, and he got along well with the crown prince, and he was a very good friend." ”

Li Rujin nodded, said "hey", and stopped talking, facing this situation, he didn't know what to say.

The emperor set out to the dock with his entourage and Li Rujin, and as for the crown prince and Li Ruhu, he went with them. Wang Jianzhong still served as a guide and commentator, constantly introducing the relevant data of this submarine to the emperor all the way, which Li Rujin told him last night, and he spent a night memorizing it.

The emperor's palace was in the shipyard, not far from the dock, and the group soon came to the edge of the dock. The crew is removing the bracket for the submarine, and at eight o'clock, the gate will be opened to release the water. It's time for sea trials.

The group circled around the dock, and the emperor was very interested in the big guys in the dock, constantly asking this and that, and even wanted to go to the submarine to have a look. In the end, this idea was dispelled under the persuasion of Li Rujin, but Li Rujin promised the emperor to wait for the dock to be filled with water, and the submarine floated up and let the emperor enter the inside of the submarine to have a look.

At half past seven, a grand launching ceremony was held on the edge of the dock, and the Emperor of the empire made a magnificent and impassioned speech. At eight o'clock, the emperor pressed the button to open the floodgates, and the sea water rushed in, gradually filling the dock.

The submarine shook and floated steadily, and the staff reported that everything was normal and that it was ready to set sail. Li Rujin asked the officers and soldiers in the submarine how the situation was, and after receiving a positive answer, he suspended the submarine for sea trials and let the emperor visit the submarine first.

The emperor boarded the submarine along the gangplank, jumped on the huge hull, felt the war monster under his feet, and then entered the interior of the submarine along the gangway, and the officers and men in the submarine urgently gathered to welcome the emperor to visit.

The space in the submarine was narrow, and he had to hunch his waist when he walked, and the emperor turned around several times in the submarine, touching his head several times, but he was still happy, and in the torpedo warehouse, he saw a huge torpedo, and the empty package of the torpedo warhead, which was used for test firing, would not be dangerous.

I went to the dormitories of the officers and men again, and when I saw the narrow beds of the officers and men, I curiously climbed up and lay down, and after coming down, I asked Li Rujin if he could make the beds bigger so that the officers and soldiers could live more comfortably.

Li Rujin explained to the emperor with a wry smile that the space of the submarine was extremely limited, and it was not easy to provide such a large space for the officers and soldiers to rest.

The Emperor stayed in the submarine for half an hour before reluctantly coming out of the submarine, and men have an instinctive love for war monsters.

The dockyard gates were all open, and the navigation and escort boats had been waiting on the surface for a long time.

The emperor couldn't suppress his curiosity, he wanted to see the submarine diving into the water with his own eyes, what could everyone do about this emperor who was not easy to play his cards? Arrange for the Emperor to board the navigation ship so that this curious guy can see it clearly.

The submarine started its electric motors, the huge propellers spun around, and the white spray rushed towards the tail of the dock. The submarine slowly sailed out of the dock and joined up with the navigation ship waiting outside. The Emperor stood at the stern of the navigation ship, watching the war beast head towards him.

After half an hour of sailing, the submarine arrived at the test area, which was carefully selected, with an average water depth of 200 meters, and the shallowest point was also more than 100 meters, with a radius of hundreds of square kilometers, which was a good place to test the submarine.

This sea area has been completely blocked, and the naval ships of the Dawen Empire are cruising in the distance, when the staff on the submarine sends a report to the command ship through radio requesting a dive.

The commander agreed to the submarine's request to dive, and a rapid siren sounded from the submarine, which was a diving alarm, and the crew was in place, and the captain saluted the command ship on the bridge, and then entered the bridge and closed the hatch.

The captain came to the command position, listened to the reports of each post, and after making sure that everything was normal, he gave the order to dive.

The sealed cabin began to be filled with water, and a large amount of air was discharged through the exhaust port, raising huge columns of water vapor on both sides of the submarine, and the scene was very spectacular. The hull began to tilt and sink, heading below the surface.

The stern of the ship also raised a column of water vapor, which was the tail seal cabin began to enter the water, but the scale was much smaller, at this time, the hull was already all under the water, and only the bridge was still exposed.

The water splashes on the sea surface, the sealed cabin is still venting to the outside, the submarine slowly dives at a speed of three knots, the diving test mainly tests three aspects, first, the underwater navigation condition of the submarine, the test depth is 30 meters, this is the most important.

Second, in the semi-submersible state, the diesel engine charges the battery through the special snorkel pipe of the diesel engine.

Third, test fire a torpedo and collect data. There are a number of other tests as well.

At this time, there was no trace of the submarine on the surface of the water, and the submarine had completely dived into the water and began to cruise underwater.

Fifteen minutes later, the submarine surfaced, the periscope was the first to emerge from the water, then the bridge, and finally the hull was exposed, the captain reported to the command ship, everything was normal, and the first test dive was successful.

Cheers and applause rang out from the command ship, and the emperor of the empire also applauded happily on the navigation ship. He also wanted to cheer, but the emperor of his empire must always maintain some grace and reserve, so he had to applaud vigorously to express his excitement.

The radio quickly transmitted the news of the success of the first test submarine back to the shipyard, and the entire shipyard was boiling.

News of success is always exciting. The shipyard became a sea of joy. From the top of the empire to the ordinary workers of the shipyards, they were cheering, jumping, and even shedding tears of excitement.

The navy of the Dawen Empire has finally seen the light of day!

The submarine surfaced, entered the surface cruising state, and the command ship slowly approached the submarine and received the submarine's test data. It was already stipulated before the test that the data should be sent to the command ship at the first time.
