The bronze door suddenly opened, and there should be a large hall inside, in the middle of the main hall, a bronze armillary sphere stood quietly, simple and unpretentious, and the dome had a coiled dragon that was also cast in bronze, except for the armillary sphere in the middle, the hall was surrounded by darkness and nothingness, and even the light shining in from the outside was swallowed up.

Yang Kai did not shy away from Yan Yuncheng, the spiritual power on his fingers flickered, and he quickly swiped on the armillary sphere, and saw that golden streamers were circulating on the armillary sphere like water, and the golden light emitted a special qi and hooked the dome coiling dragon.

The coiling dragon sensed the armillary sphere, a pair of eyes suddenly opened, shooting out two brilliant golden lights, straight down on the armillary sphere, the two golden rays were just like a silk thread connecting the two, the armillary sphere was pulled by the silk thread, slowly swirling.

As the speed of the armillary sphere's rotation accelerated, a golden light gate appeared in front of Yang Kai and Yan Yuncheng, Yang Kai stepped into the light gate first, and Yan Yuncheng did not hesitate at all, and walked in closely.

After a dazzling light, Yan Yuncheng opened his eyes, and what caught his eyes was a dazzling array of bookshelves and books, which gave him the illusion of entering the 'Tibetan Scripture Enchantment' of the Jixia School Palace, but to Yan Yuncheng's secret happiness, there was no annoying old Jia Tou here.

Yang Kai led Yan Yuncheng through the rows of tall bookshelves, and finally stopped at a place marked with military registration, looking at the bookshelves like a hill, as well as the military registration books displayed on the shelves, he suddenly felt that his head was as big as a fight, when did the two of them have to check so many books?

Obviously, Yan Yuncheng thought about it a lot, and saw Yang Kai walk directly to the side of the bookshelf, and there was a square thing that seemed to be made of jade on the side of each bookcase, Yang Kai put his hand on the jade slab, and seemed to go to the next bookshelf after feeling it.

After more than ten bookshelves like this, Yang Kai stopped, and with a few taps on the jade slab in his hand, a scroll flew down from the bookshelf, which happened to fall into Yang Kai's hand, and a few big characters suddenly came into view, and it was the six big characters of 'Zu Qianqiu's military registration book'.

Yang Kai directly handed the scroll to Yan Yuncheng, Yan Yuncheng thanked him and couldn't wait to open the scroll, but when he saw the contents of the scroll, the whole person was dumbfounded.

"What's wrong?"

Yang Kai saw that Yan Yuncheng's expression was wrong, and asked, Yan Yuncheng frowned and handed him the scroll, Yang Kai took a look at it and frowned, the ancestral hometown of the ancestor Qianqiu on the military registration book was actually erased.

At this time, the shock in Yang Kai's heart was no less than that of Yanyun City, this volume was all made of Tianxuan silk, Tianxuan silk can not decay for thousands of years, and its toughness is even more terrifying, and the ink used for writing is more and more precious, it is made of the bile of the sea clan's Zhonghua Dragon Realm Kraken Ink Beast, and if you want to erase the traces of its formation, you have to be higher than the Dragon Realm cultivation.

"Who made the move?" Yang Kai wondered in his heart.

Yan Yuncheng was silent, secretly thinking that this matter had become more and more confusing, it seemed that there was a big hand secretly controlling everything, he erased all the clues in advance, and the clues that Yan Yuncheng could find were broken here.

There was no result here, and there was no need for the two of them to stay here, and when they got out of the main hall and boarded the carriage, Yan Yuncheng and Yang Kai did not speak, and the carriage went directly to the Baichuan Inn.

"Please bring a message to Ah Yu for me and tell him that he will always be my brother!"

Yang Kai didn't get out of the car, and when Yan Yuncheng was about to enter the inn, Yang Kai suddenly said so, Yan Yuncheng's figure paused without looking back, shook his hand and walked in.

"Did you hear it all?"

Yan Yuncheng pushed open the door of the room upstairs, and Hai Linyu was standing at the window, quietly watching the carriage in the distance, and did not turn around until the carriage turned the corner.

"Thank you!"

Although Hai Linyu said it plainly, Yan Yuncheng heard the incomparably sincere feelings.

"Knock knock!"

"Young Master Yu, it's not good, the one hundred and sixty-first sentinel found the traces of the Sea Clan. A hurried knock came at the door, and the shopkeeper ran in with a slightly flustered look and said quickly.

When Hai Linyu heard this, the two sword eyebrows rose upside down, and the evil qi on his body gushed out, and he raised his legs and walked outside, but he was stopped by Yan Yuncheng.

"I'll go too!"

Hai Linyu hesitated for a moment, but nodded in agreement.

On the wall of the 161st outpost, the surroundings were already full of people with guns and halberds, and the bows and crossbows that had accumulated violent energy were lined up, Yan Yuncheng and Hai Linyu stood side by side, looking out into the sky, the wide sea was calm and calm, and there was not even a single seabird, it was too calm.

"It's coming. ”

"Ready. ”

Yan Yuncheng and Hai Linyu opened their mouths at the same time, and at this time, they saw that the rough sea surface began to appear with subtle ripples, slowly turning into waves, the waves became bigger and bigger, and they crashed wildly against the rock wall, making a thunderous sound.

At the first line of the sea and sky, a water wall formed by a monstrous wave is connected like a mountain range, and the speed is extremely fast, and in a blink of an eye, it is close to the Royal Sea City, and the water wall pushes horizontally, hitting the towering city wall of the Royal Sea City fiercely.

The walls of Yuhai City were built very strongly, the huge waves slapped on the city walls without a trace of vibration, and the soldiers on the city walls were full of strength and spiritual power, and the huge bows and crossbows were like dormant beasts, just waiting for an order to be fired at the same time.

Wave after wave, wave after wave, frantically crashing against the city wall, the city wall was as steady as a mountain rock, and the sound of the turbulent waves was deafening.

"Roar!"

A powerful roar came from the depths of the seabed, and the sea surface suddenly tumbled violently, and a huge whirlpool suddenly appeared, a huge whirlpool stirred the seawater, and a dark black hole was formed, which seemed to be able to swallow the sun, moon and stars.

Suddenly dark clouds covered the sea area, and the wind and rain poured down, and the heavy clouds suppressed the people breathlessly.

The whirlpool was like a bottomless pit, the sea water was constantly pouring in, and a behemoth rose from the whirlpool, its huge body was the size of a hundred zhang, its blue-gray skin was covered with hideous and twisted lines, and its mouth was full of fangs and cold light.

"Tiger Shark!" Seeing the comer clearly, Hai Linyu's face was extremely solemn.

The tiger shark leaped in the air, and finally landed in the sea, splashing a huge wave, floating on the sea as high as the walls of the Imperial Sea City, a pair of eyes were blood-colored, and the ferocious aura roared like a hurricane.

"He's got someone on his back!"

The tiger shark calmed down at this time, floating on the surface of the water, confronting the people on the city wall, more than a dozen figures appeared on its back, with the strength of Yanyun City's spiritual sense, they had already seen them clearly, these people, more precisely, should be humanoid creatures, because although they had human bodies, their bodies were covered with scales.

"That's the Sea Clan. ”

Hai Linyu also saw the people who came clearly at this time, he knew that Yan Yuncheng was the first time he had seen these Sea Clansmen, so he immediately explained for Yan Yuncheng.

The sea tribe is also called the sea people, or the mermaids, the spring first, crying tears into beads, good at weaving silk, called dragon silk, the dragon silk into the water is not wet, the sea tribe is similar to the human race, the whole body is covered with scales, the color of the scales to distinguish the strength of the sea people and the nobility, in turn increased to white, green, black, green, red, silver, gold seven colors, ferocious and aggressive by nature, good at manipulating sea beasts.

Listening to Hai Linyu's introduction, Yan Yuncheng looked at more than a dozen people, and found that only one person was white-scaled, and the rest of the people of the Sea Clan were all black-scaled, but all the black-scaled people respected the white-scaled Sea Clan and protected them in it.

"How are the forces of the Sea Clan divided?"

Since this White-scaled Sea Clan can have the protection of a group of Black-scaled Sea Clansmen, it can only mean that their identity is not simple, so Yanyun City is interested in the distribution of the Sea Clan's power.

"We don't have detailed information on how the power of the Sea Clan is distributed, the sea area is too vast, there was once a Terran master who dived to the bottom of the sea, and there was very little news that he finally brought back, but over the years, from the captive Sea Clan, we have learned some news. ”

"I only know that the Sea Clan has a city similar to the Terran, called Sea City, according to the size of the Sea City, the sea area controlled by the representative forces is different, and the various forces of the Sea Clan are also fighting endlessly. ”

Due to the complexity of the situation under the sea, human beings' understanding of the Sea Clan is very limited, and the only information is also learned from the Sea Clan captives, and Hai Linyu only talked about some of the things he has learned, and he has no way of knowing the greater secrets involved.

"They live in the sea, why would they attack the city on land?"

Yan Yuncheng asked the biggest confusion in his heart, the sea tribe lives in the deep seabed, the sea area is far wider than the land, there should be no possibility of limited living space, and the land is not suitable for their survival at all, so why do they desperately attack the land city?

"I don't know, it seems that they are born with hatred for the human race, and the hatred between the human race and the sea race has not only not faded with time after thousands of years of conquest, but has become more and more intense. ”

Hai Linyu's eyes are deep, the cold on his body is compelling, he can be said to hate the Sea Tribe, because his father was killed by the Sea Tribe, his father was also the defender of the Sea Clan, and he was killed in a Sea Clan attack, and his mother died due to excessive sadness, and he became an orphan before being adopted as a righteous son by Hai Yuanyou.

Over the years, seeing countless soldiers killed by the Sea Clan, his hatred for the Sea Clan has become more and more profound.

"Can the people on the city wall dare to go out of the city to fight?"

A shrill voice, the sound of breaking through the waves and lapping against the waves, clearly reached the city wall, and it was one of the Black Scale Sea Clansmen who spoke among the dozen or so people.

"Put!"

Hai Linyu ignored the clamor of the Sea Clan, and gave an unusually decisive order, the spiritual light on the bow and crossbow was brilliant, and the spiritual arrows carried violent energy, overwhelmingly coming out towards the tiger shark like a meteor falling, and the sharp whistling sound made people's hearts palpitate.

The crossbow arrows were instantaneous, and the huge body of the tiger shark became a live target in an instant, and the spirit arrows directly broke through the tough skin of the tiger shark, shot into its flesh and blood, and then burst into the flesh and blood, and for a time the tiger shark flesh and blood flew sideways, blood flowed sideways, and the terrible beast scream was earth-shattering.

More than a dozen people on the back of the shark were instantly overwhelmed by the locust-like spirit arrows, the tiger shark became extremely irritable, swinging wildly in the sea water, and the water walls rose out of thin air, crashing towards the city wall, but after all, they couldn't bear the severe pain, as well as the fierce attack of the bow and crossbow, and finally had to dive into the sea water.

After waiting for half an hour and not seeing the tiger shark reappear, the sea gradually became calmer, the wind and clouds dissipated, and the sky was blue again, but the blood-red sea water was still dazzling.
