The silent return of tide is a natural phenomenon unique to Phuket.

Every year at the turn of spring and winter, around the Forbidden Demon Festival, when the rejuvenating Yang spits out the first buds, the school of rays from the deep sea will return from afar with their fat and strong bodies, and migrate all the way up along the wide and deep silent river.

There are clouds in ancient books: Wen ray, like a carp, fish body and bird wings, cangwen and white head and red beak, often travel in the West Sea, swim in the East China Sea, return to Phuket, fly at night. Its sound is like Luan chicken, its taste is sweet and sour, and the food has been crazy, and the world is big when you see it.

Some people say that the rays return to Phuket Island because they want to migrate to the shallows of the upper reaches of the river to have children and maintain the continuation of the group, others say that they want to cross the 'dragon gate' at the end of the silent river, fade away from the body of the fish, and turn into dragon beasts, and others say that these swimming fish are the gluttonous rations of the deep silent forest, and every spring, when the gluttony wakes up, it will summon its rations to swim back into its mouth.

In any case, the migratory road is an arduous journey for these rays.

From the Aral Sea to fresh water, from wide waters to rushing rivers, and the waterfalls and dams that stand on the silent river, not to mention the many monsters on both sides of the riverbank, and the hunters from the sky and the water.

Even if the fish had wings, pointed beaks, and poison, they couldn't stop the monsters on the island from starving for a winter.

It was a feast for the inhabitants of the forest.

An annual feast.

"This year's return to silence is a bit earlier than in previous years. Dr. Duzem lowered his head, patiently blended the doses of different powders, and casually explained to the two young wizards:

"In most years, the rays migrate in early spring. ”

"At that time, they were nourished by the deep sea for a winter, and they were fat and strong, full of strength, and with a flick of their wings, they could leap from the mouth of the Silent River over the triple waterfall, and their red beaks pecked lightly, and they could break through the back skin of horses and bears. ”

"The monsters in the Silent Forest have been hungry for a winter, and they are not inferior to these flying fish. ”

"The prey and the hunters fought from the lower reaches of the Silent River to the upper reaches of the river, and for a whole month, most of the Silent River was dark red. ”

Zheng Qing imagined the tumbling river and the red river, and couldn't help but be dazzled.

"But now, the large schools of rays have returned from the bottom of the sea ahead of schedule, and the beasts on both sides of the river, who have just been fattened by the abundant food of the summer, are unwilling to fight these swimming fish for their lives, so they are left to their own devices. ”

"Sounds like that. Zheng Qing pondered and muttered in a low voice: "Wen rays can migrate with confidence, and the animals on both sides of the river don't need to die at the bottom of the river for a few mouthfuls of fish...... It feels like a win-win. ”

"Win-win?" the doctor looked up and gave him a sarcastic look, "How did you end up on a public scholarship?

Zheng Qing blinked, looking at the doctor who suddenly spoke ill of him, a little inexplicable.

"It's not a win-win, it's a total loss. The doctor raised a finger and shook it quickly: "Every ecological chain has an unusually precise, sensitive, and fragile structure. Any unstable fluctuation in the ecological chain, transmitted to the upstream and downstream ends of the chain, will cause irreversible huge changes. ”

"Take, for example, the resurgence of silence. ”

"Every year in the desperate battle on the Silent River in early spring, a large number of Wen Ray and demonic beasts from the Silent Forest will always die. When the migration is over, the number of monsters in the forest and the ferocious fish will drop to a level that reassures the wizards...... A quantity that does not pose any threat to wizards. ”

Not to mention that the flesh and blood of both sides nourished the vast forests along the banks of the river, such as the Rejuvenating Poplar and the Unyielding Willow, and fed countless weak creatures at the bottom of the river and on the bank...... There is also the northern district of Beta Town, where the tricksters count on this season to fish some pieces of meat from the river and marinate some bacon for the festival. ”

"Without fighting, a large number of rays poured into the upper reaches of the Silent River, which could have some serious consequences. For example, they will eat up the small creatures on both sides of the riverbed, and they will feed some of the existence imprisoned by the Witch League in the depths of the forest. ”

"In other words," Jiang Yu also immediately came to his senses, and said, "The Sand Shi Group, the Red Chain Snake, and those corpse-eating beetles, all of them escaped into the school to avoid the predation of these fish?"

Zheng Qing suddenly realized.

"Just one of the reasons. The corners of Dr. Duzem's mouth twitched, and a gentle smile hung on his face: "The passage of a large number of rays not only threatens the safety of those little bugs, but also eats up their rations...... For example, the red chain snake has a big overlap with the ray in the recipe, the fish eat up the bait, the big snakes can still hide in the hole, close their eyes and pretend to hibernate, those small snakes can only sneak into the school to see if they can find a few bites to eat. ”

"That sounds pathetic. Zheng Qing smacked his lips, remembering a certain little snake that was taken into the nest by the old hound, and mourned for a few seconds for their miserable fate.

"They have been living in this environment and there is nothing pitiful about them. Dr. Duzem shook his head and emphasized, "It's the town of Beta that is really pitiful, the low-level wizards in the south of the town and the tricksters in the north. ”

"The school of rays is only that big. ”

"Now that autumn has swam back, spring is definitely gone. ”

"What will the beasts that have been hungry for a winter in the Silent Forest do when they crawl out of their burrows and find that there are no fat swimming fish in the river?"

Zheng Qing swallowed his saliva quietly, turned his eyes to the window, and looked at the shadowy buildings in the distance.

Dr. Douzem's cold voice continued to ring in his ears.

"A hungry beast can do anything. For example, attacking a small common area of First University, or attacking wizards entering the forest...... When all else is said and they are in a desperate situation, these beasts will never mind rushing up and pouring into this town full of food. ”

"Why can't we see those rays now?" Zheng Qing suddenly asked.

If, according to the doctor, this year's return to silence was a few months earlier, then in any case, students should find some clues.

In addition to the fact that the southern part of Beta Town is adjacent to the river and has a wharf, the campus of First University alone has many public areas built on the banks of the tributaries of the Silent River, as well as Linzhong Lake, which is also part of the Silent River.

"Rays are nocturnal creatures that sleep at the bottom of the water during the day and glide across the river at night. So the first people to notice the migration of fish were the low-level wizards in the Southern Side who got up in the middle of the night to work. ”

Speaking of this, Dr. Duzem paused, and shook his head: "What's more, you young people, hiding in the guardian circle of the First University all day long, how can there be a guy who doesn't have long eyes to touch your moldy head at will!"

......

Time flies.

By the time the elves had taken the latest batch of potions, it was nearly eight o'clock in the evening.

The Doctor sent two young wizards to the door.

"You should be more concerned about your health than these elves. ”

Before leaving the institute, Dr. Duzem reminded Zheng Qing in a heartfelt manner: "If you fall before these elves are truly free, then their tragic future will not change in the slightest. ”

"I'm healthy. Zheng Qing smiled reluctantly, bent his arms, and puffed up the muscles in his arms.

"No healthy wizard would have two big bags under his eyes, dark circles under his eyes, and bloodshot eyes...... I still have nightmares every day. Jiang Yu couldn't help but say beside him: "I think what the doctor said is very reasonable." ”

Zheng Qing smiled and glanced at Dr. Duzem.

The Doctor's dark circles are much worse than his.
