Early the next morning, Yu Xian put on a neat admiral uniform and entered the Admiral's Mansion again to enter the daily work, and the ship's girls were also ready to slide out of the harbor according to the plan to carry out the daily attack on the deep-sea combat mission.

"Nana~ Don't you think the deep sea has been quiet lately?"

Yu Xian said to his Nana wife after processing the documents.

"Admiral, do you still want to see the impact of the deep sea?"

Helena said angrily that now after the unification of the world, they are all compatriots of the same country, and death is a loss for their own people!

"No~ It's just curious, I remember that last time a mine owner dug up a vein and blocked a group of deep-sea fleets in an underground tunnel, it was incredible~"

Yu Xian recalled the expression on the face of the mine owner who was about to die when he dug out a deep-sea fleet. But that guy was lucky and did a good job, if he hadn't dug up the ore veins and blocked the way to the deep sea, those deep seas would have gone down the underground tunnel into the interior to wreak havoc!

Later, Yu Xian mobilized his elite ship girls to kill the group of teasing deep seas, but the deep sea roost escaped along the tunnel... It doesn't hurt either. Later, after Yu Xian cleaned up the collapsed tunnel underground, he found that... This underground tunnel was dug by hand and is over 30,000 years old! So how long have humans been around? Follow the tunnel inland, and finally walk out of a giant cave on the peak of a snow-capped mountain in the West Z Plateau......

And Yu Xian also fell into deep thought, these don't seem to be excavated by humans, and the workload is too great, and there are many biological bones in the cave... As well as murals and texts! Later, under the orders of the Queen, many troops were sent to search for it, and the entrances to such caves were found in all the states, and these tunnels connected the continents in the pitch black underground... It seems that the species that excavated this deep underground cave is very powerful, but why is it not documented? Could it be that "they" live in the Inner Earth?!

There used to be many myths and stories in this world, but they were all destroyed when various disasters came... What kind of catastrophe can destroy an ancient civilization that can't even leave a trace? Let's take a look back at the history of the earth...... Five billion years of Earth's history, and then humans emerged in 50 million years...... Now it doesn't take long to add up, but it has formed a wisdom system and civilization... So what happened to the Earth before?

A lot of doubts are formed in the mind of the virtuous, but there may be too much to think about...... Subsequently, a number of unmanned monitoring stations were set up in the underground tunnels to record and transmit the effects back to the surface, and perhaps one day the secrets of the place could be discovered.

"Today's work is done, let's go to the ship's girls' entertainment room to relax together, right?"

The time came to eleven o'clock in a blink of an eye, and Yu Xian suggested to Helena.

"Let's go, Admiral~By the way~ Why haven't you seen Missouri for a long time?"

Helena asked Yu Xian.

"Missouri took my friends to visit other Admiral's Mansions for exercises, and I should be back in a week."

Yu Xian looked at the timetable and said, and then took Helena to the ship's dormitory.

In the dormitory, the eldest princess is playing a simulated battle flag game with her friends~ As for the opponent? It's VV and Elie sauce, as well as the little bugs who make trouble on the side and the stupid guy who was cleared out of the game by the boss and was labeled as a murderer~

The whole game room was very happy in the music, and Yu Xian quietly looked at it and pushed Helena in, but he shook his head and said:

"I suddenly remembered that there is still something to do, you come to play for a while and relax, and I will be back in a while."

Helena nodded and entered the playroom.

Yu Xian came to the special transformation room in the core area of the base... Outside the renovation room, I was surprised to see the unbridled arcs everywhere inside the glass...

At this time, Freya appeared next to Yu Xian.

"Your ability is really convenient~"

Yu Xian said as he watched Freya appear beside him in Shunma.

"Of course~ The entire Moon Bay is built on my body~ I can go there if I want to~"

Freya said proudly, and Yu Xian whispered something in her ear, and her face turned red.

"Yah~! Why do you only think about these weird things all day long! Hmph~"

Yu Xian looked at the embarrassed Freya full of mischievous fun. Then he said:

"Freya~ Why did Bismarck take so long to evolve this time? And this scene looks weird......"

Freya walked over to the transparent window of the renovation room, knocked lightly on the glass, and said:

"Admiral~ This ship girl is a ship girl who has accumulated and broken through to the Divine Mansion stage on her own, so her strength will become very strong! And those arcs didn't hurt her, they strengthened her! According to the inferred time, Bismarck will complete its self-transformation today~ but I am not sure of the specific time. ”

Yu Xian only has two ship girls who have reached the stage of the Divine Mansion! I didn't expect it to be a cat house and their two sisters~

Yu Xian, who was in a daze, suddenly saw all the arcs shrink back to the middle base point, and then a delicate figure appeared in front of Yu Xian!

Squeak~ The door to the transformation room opened, and then the figure walked towards the admiral she was familiar with.

"Bismarck has been transformed! Admiral: Let our enemies feel the power of the thunder! ”

Yu Xian's eyes widened and he looked at Besmarck in front of him, he couldn't believe that Sister Cat was so bold~ She walked in front of him without even wearing clothes! Hey~ Don't say it! The cat's figure is really good~ Straight and full European style, snow-white skin, slender legs and unique temperament make the cat very attractive.

Bismarck tilted his head, not understanding why the Admiral didn't react to his words. At this time~ a gust of wind blows...... Bismarck felt a chill on his skin, forehead (⊙o⊙)...! It's hard to look down! We meowed nothing and appeared in front of the Admiral!!

"Babble~!"

Bismarck slapped him at a speed that Yu Xian didn't even see, and then screamed and squatted on the ground with Opai in his hands. Yu Xian, on the other hand, felt that the snow-white body in front of him was gone, and then the scenery spun wildly, and then rolled to the ground by himself......

"Puff~"

Freya, who was watching the joke from the sidelines, couldn't help but laugh.

Yu Xian got up from the ground, then took off his coat from the Admiral's Mansion and put it on Bismarck, and turned around and said angrily:

"Why are you smiling at and can't help out?"

"I just like to laugh~"

Yu Xian looked at Freya in front of him, and made a finger with a black line on his face, and then in a snap~ The clothes on Freya's body disappeared in an instant, and became the same as Bismarck, and the white fruit was presented in front of Yu Xian!

"Babble~!"

Freya was stunned for a moment, then screamed and ran away covering her body~ Yu Xian shook her head and looked at Freya who ran away, didn't she know to take out her clothes from the subspace? Or condense a ship's outfit? What a fool!

"Admiral... The Admiral doesn't think I'm a pervert, does he?! ”

At this time, Yu Xian felt that his pants were being pulled, and when he looked back, he saw that the cat was talking to himself with tears in his eyes.

"Of course not~ and the Admiral will make you very strong~"

"Really?!"

Bismarck looked at Yu Xian excitedly.

"Of course~"

Then Yu Xian pounced on Sister Cat, picked her up and teleported her to the back of a palace's big bed, bringing Sister Cat to the pinnacle of heavenly happiness, thus using this special method to raise her level to one hundred and fifty! (The process is added to the outer luxury package~ I can't drag race in the text, please forgive me, and Binghan has been uploaded in the group and deleted before this afternoon.) ）
