Jian Rin Sakura was in the greenhouse of the Imperial Building, watching Liu Dun's research results these days.

In this room of more than 200 square meters, there are large and small square pools.

Originally, this house was used for experiments on sword-forging materials, but now it is used to raise all kinds of strange creatures in the sea.

In order to find the crux of the problem, Liu Dun kept all the unknown possible objects they had caught from the sea in a separate pond and cultured them, while stocking the same fish to facilitate observation and comparison of previous fishbone events.

After about ten days of screening, Liu Dun roughly determined the goal.

"Your Majesty, look." Liu Dun raised his hand and guided Jian Rin Sakura's gaze.

Inside the pool, the remains of dead clownfish float in the crystal clear waters.

The light poured in, reflecting a black ghostly figure in the corner.

It wagged its tail a little, then swam quickly.

"As long as there is enough food, it can continue to reproduce, by the way, it is strange to say, they are like they don't need a mate, even if there is only one black snake, they can automatically lay eggs and hatch, such an ability is simply ......"

Liu Dun couldn't find the right words to describe the surprise in his heart for a while.

Including the number of such creatures in the sea now, it is only a vague imagination, and it can only be roughly estimated with as many as the seawater......

Jian Rin Sakura nodded, crouched down, and looked at the pool with a grim expression.

Floating on the surface of the water, it looks like dense bubbles, and the small transparent black dots inside are faintly visible in the light.

The black snake that was caught ten days ago has now successfully held its eggs.

There are a few that are about to burst out of the egg.

In the corner of the transparent pool, a small snake the size of a finger can be seen swimming back and forth, and when it sees the sword Rin Sakura, it looks up as if it is spiritual.

The snake's tail swept back and forth, the side fins on both sides of its body spread out like petals, and its body was suspended, silently staring directly into Kenrin Sakura's gaze.

"It's ......"

It was a strange feeling, and it seemed to feel a distant and desolate aura on its body.

"Compared with the bite marks on the fish bone before, it should be this thing, and it is very aggressive, Your Majesty had better not get too close to it."

Kenrin Sakura nodded, straightened up, and brought her hands to her chest.

"So, is there a solution?"

Liu Dun's face was solemn, and then he slowly shook his head.

"The world is so big, there are no wonders, and there is really no good solution to this thing."

"How is this a good ......?"

Kenrin Sakura bit her lower lip tightly.

I thought that once I could get the answer, all the problems would be solved, but who knew that in the end, there would be no way.

How is this not frustrating......

"However, Weichen vaguely remembers that there seems to be a similar record in an ancient book."

"Really?"

Kenrin Sakura turned around excitedly, as if grasping at the last straw, and the light flashed in her eyes.

……

Although the Imperial Library of the Dream Sword Country is not as large as that of the Heavenly Sword Kingdom, it is also rich, especially for the knowledge collection related to the sea, its scale is large, the coverage is wide, and the records are strange, which are incomparable to other land countries.

The surrounding lights have been shining for thousands of years, and at this time, they are also fulfilling their duties, illuminating the huge square space.

The large marble library is lined with huge bookshelves.

They were like vines, stretching up from the ground to the golden dome.

The heavy shelves were filled with old books of different colors, some of which were encapsulated in parchment paper and looked older, and the books displayed at the top, although clean, were also yellowed and peeled off by the passage of time.

Liu Dun raised his head and carefully confirmed the name of each book, the light in the room was very dim, which took him a lot of time.

It was in the dim light that Jian Rin Sakura suddenly discovered that he didn't know when it began, and the chief swordsmith of this imperial building house already had a lot of gray hair on his head.

It would be nice if I could work harder, help him share more, and absorb more knowledge.

"Found it."

Liu Don's voice pulled her back from her thoughts.

He raised his hand and circled gracefully in the air, an ancient book on top of it gently lifted and floated down like a light feather.

Liu Dun carefully held it on his wrist and gently dusted off the paper.

The book is large, about half a meter long and wide, bound with thread, and the edges are badly worn.

Liu Dun tipped cautiously with his fingertips, for fear that one would destroy it if he was not careful.

It was at this moment that there was a knock on the door, and the voice of the guards came from outside the door.

"Your Majesty, the palace asks to see you."

"Emiya?" Jian Rin Sakura smiled happily, "It's so good to come, invite him in!" ”

With the faint sound of conversation and footsteps outside, half of his body leaned in outside the door.

Emiya's familiar delicate face appeared in Kenrin Sakura's sight.

The feeling of not seeing you for a long time.

His lines were perfectly outlined by the light in the room, and Emiya smiled and walked towards Kenrin Sakura.

"I've seen Your Majesty."

"Where do you get so many courtesies?" Kenrin Sakura laughed with her hands folded in her arms until Emiya stood beside him.

The sleeves of the two men gently pressed against each other, making a rustling sound.

Jian Rin Sakura suddenly felt-

It's so reassuring.

"Recently, there have been some strange phenomena where the fishing boats have not been able to catch fish, and the whole sea is like something has suddenly eaten up except for the bones and debris."

Kenrin Sakura explained to Emiya, "Half of the food source of the Dream Sword Country is seafood, and now this half has suddenly evaporated, and it is inevitable that it will fall into a food crisis, although I have already bought food from other countries at high prices, but it is a drop in the bucket, and if the important problem is not cured, everything is in vain." ”

"It wasn't until a few days that we caught the culprit from the sea." On the side, Lord Liu Dun took over the conversation, he bent down slightly, and said to Jian Rin Sakura, "Next, let the minister explain." ”

Liu Dun led the two of them towards the reading table in the middle.

He gently placed the book he was holding on the table, then carefully flipped through it, stopping at one of the pages.

It depicts a beast that has been pitch black all the time, revealing a half-long body on the rough sea, like a huge whirlpool that wants to suck people into.

Compared to the wooden-hulled ship and small island depicted later, the monster is a little frighteningly large.

Blue whales?

No, it's ten times bigger than a blue whale.

It's just that this book looks so old, and many times, it is suspected of exaggeration in ancient legends.

Liu Dun read it word for word, then raised his head and explained, "It says that this is a very ancient ancient creature that feeds on all the fish in the sea, and eats an astonishing amount of food, and is very capable of reproduction. They will also work together to complete hunting tasks, and they can also come together to form large and terrifying individuals......"

When Wei Gong heard this, a certain nerve in his brain suddenly touched.

This kind of description is like the alien zerg in science fiction.

Could it be that they also have a mother?

Emiya put his finger to the tip of his nose, and a strange smile appeared on the corner of his mouth.

It would be much easier if that were the case.
