Harry Potter and the Old Ones

Then Tiera jumped into the lake herself.

"Tiera!" Harry said, seemingly angry, "What are you doing?"

"Just in time, your gillweed still has some time." As Tiera said, gills also appeared on her neck. Her hands and feet were elongated, and the fingers were connected by webs. Harry saw Tiera's smooth and delicate body. foot--

The feet became longer, and there were webs connecting the toes, as if they suddenly turned into duck webs.

"You, you too..." Harry asked in surprise.

"No, Harry." Tiera swam closer to Harry, and then whispered in his ear, "This is flesh and blood magic."

"Flesh magic?" Harry asked in confusion, "What is this?"

"This is a kind of magic that, in addition to the three forbidden spells, will be sent to Azkaban immediately once it is learned, used and spread." Tiera smiled, swam forward, and then said, "It's an extremely evil black magic."

"Huh?" Harry seemed startled. His mouth was so big that he could fit a fist into it.

"Then, then, then you..." Harry felt his tongue was a little tied.

"Harry, do you believe me?" Tiera asked, "I have told you my biggest secret."

"I" Harry hesitated at first, then said firmly, "I believe in you, I believe in Tiera!"

"Hehe." Tiera smiled, then pulled Harry and swam forward for a short distance.

"Those who use black magic are not necessarily bad people." Tiera turned back and said with a smile, "Harry, I hope you can remember this."

"Yeah," Harry replied, "Tiera is not a bad person."

"Yes, Harry, and I can also use flesh magic." Tiera said with a smile, suddenly became serious, turned around, held Harry's head, and stared directly at Harry -

"What, what?" Harry was a little nervous because of Tiera's series of abnormal movements.

"Harry, remember, what magic do I know?" Tiera asked seriously.

"Blood, flesh magic." Harry replied with some confusion.

"Yes, Harry, remember, I can do flesh magic, but I am not a bad person." Tiera said, "Remember, I am neither a bad person nor a good person."

"How is that possible?" Harry asked in confusion, "You are a good person!"

Harry said a little stubbornly.

"No, Harry, you must remember that I am a smart person, and I am a precocious and precocious person." Tiera said, "But I am by no means a good person, and I am by no means a bad person."

Tiera clamped Harry's head with both hands, forcing Harry to look directly at her, "Harry, you must remember that I am a very complicated person who can use black magic."

"Okay, okay, I remember." Harry said helplessly, and then pushed Tiera's hand, "You hurt me a little."

"Sorry, Harry." Tiera let go of her hands, and then said with a smile, seeming to have returned to her usual happy-go-lucky and quirky Tiera.

"Let's go, Harry." Tiera said with a smile, "Let's go and play under the Black Lake. During the previous game, I don't think any of us took a close look at the beautiful scenery inside the Black Lake."

"Yeah!" Harry happily agreed and swam after Tiera.

They swam around in a strange, dark, hazy landscape, and there was silence in their ears.

Harry could only see within a ten-foot radius, so every time he paddled in the water, a new view suddenly emerged from the darkness in front of him:

A jungle of undulating, tangled black water plants, and wide, flat stretches of sand scattered with shiny pebbles.

They swam deeper and deeper, heading towards the center of the lake. His eyes were wide open, looking through the gray and strange lake water, looking at the black shadow in the distance, where the lake water was dark and hazy.

The little fish swam past him lightly, like silver darts.

Once or twice, he seemed to see a big thing moving in front of him, but when he looked closer, he realized that it was just a big black log or a dense and tangled aquatic plant.

Tiera seemed to be able to see further than Harry. Tiera, who was leading the way, was like a mermaid in fairy tales and legends in the Muggle world. Her soft skin was so white that it was dazzling in the dim lake bottom, and she wandered gracefully in the dark. Among the aquatic plants and fish at the bottom of the lake.

Harry didn't know why Tiera had such good eyesight at the bottom of the lake. Harry guessed that maybe it was because of the flesh and blood magic Tiera mentioned. Tiera could always help Harry avoid obstacles, and she was able to avoid obstacles in the lake. Large creatures wandering in the lake——

For example, the giant squid often comes to the surface to bask in the sun.

Tiera and Harry first came to the Slytherin common room——

outside the window.

Only then did Harry realize that the Slytherin common room was so deep underground. There was a huge glass window inside, and outside the glass window was the bottom of the Black Lake.

Through the glass window, Tiera and Harry had a panoramic view of everyone in the Slytherin common room——

Unlike the Gryffindor common room, which is always filled with golden sunlight and warm decorations, the Slytherin common room is a long, narrow, low basement with walls and ceilings made of rough stone, rounded Round, glowing green lamps were hung from the ceiling on chains.

Tiera and Harry could see that on the right side of the huge glass window, there was a fire crackling under a beautifully carved mantelpiece, reflecting several people sitting on carved chairs around the wall. Figures of Leitlin students.

Because it was lunch time, the Slytherin common room seemed a little empty now. Tiera and Harry just glanced at it for a few times and swam away quickly.

Tiera and Harry swam some distance toward the center of the lake. Suddenly, many rough stone dwellings appeared in all directions, speckled with algae.

Harry saw some faces in those dark windows... These faces were completely different from the mermaids on the painting in the prefects' bathroom...

Apparently, this is a mermaid village near the ruins in the center of the lake.

Tiera and Harry only walked around the perimeter, then turned around and wandered away——

After all, Tiera had just overthrown their lair. If these mermaids discovered it, Tiera herself wouldn't care, but it would be a bit difficult to fish Harry out without exposing her strength.

Because the action time of the gillyweed was about to expire, Tiera and Harry did not continue wandering, but swam towards the lake shore.

As they approached the lake shore and were about to land, Tiera suddenly grabbed Harry——

"Harry." Tiera approached Harry and said with a smile.

"What, what's wrong?" Harry asked nervously.

"Whatever is under the lake, let it stay under the lake." Tiera said with a smile, stretched out a finger and raised it to her lips, "This is our secret."

I'm really sorry, because I have to plant rice tomorrow, I was busy mixing soil and soaking soil until ten o'clock today, so the update is a little late. Thanks for putting it in tomorrow's chapter.
