HP: After binding to the strongest wizard development system

Professor Snape looked at the little girl who was hanging her head in silence. He felt that there was nowhere to vent his anger. He glared at Till several times and started teaching again.

Professor Snape still taught Teal about potions, but instead of having Teal ask questions, he would explain one potion every week and take Teal to refine it. Teach Till the idea again.

Till didn't have any objections. No matter what Professor Snape taught, she still didn't understand it. If she listened carefully and studied carefully, she would not suffer any disadvantage.

Returning to the dormitory in the night cover, Tier yawned lazily, went to wash up first, then lay on the bed and re-entered the study room.

The system "teacher" knew that she would come in again and was already waiting for her at the table. The book that Till had read in the afternoon was also safely spread out on the table, waiting for Till to visit again.

[Host, maybe you can take a rest tomorrow? Once the faith value is exceeded, this system can be upgraded to level 5, which takes 5 hours. 】The system "teacher" suddenly spoke, which surprised Tier.

【Is faith worth it? I thought it needed faith value. 】Tiel was surprised at first. According to the previous rules, she always thought that the faith value required for system upgrade would increase tenfold. Unexpectedly, this time it would only be more.

But... Tier frowned again: [I haven't been out much recently, so why do I still have so much faith? And can't you wait until I fall asleep to upgrade at night? 】

[The host's faith value will increase every day. According to the source, it seems that your friends are increasing your reputation outside. As for upgrading...] The system is telling lies with its eyes open, and the mechanical sound does not sound guilty. [System upgrade needs to be done in This can be done when the host is awake, but cannot be done when the host is sleeping or comatose. 】

Tier responded softly, but she didn't plan to take a rest tomorrow. Even if she couldn't enter the study room during the system upgrade, she could still go to the library to read.

Although the previously planned annotation work has been suspended, I may be able to do it for a few more hours tomorrow.

The system had made up its mind to ask Tier to take a rest tomorrow, and even held off on upgrading until tomorrow, so it naturally had a backup plan. When Till got up early the next morning, the first thing that greeted her was the sound of a new task in her head.

【Ding! Short-term task nine: Enjoy the morning away from studying. Reward for completing the task: a happy mood. 】

Immediately afterwards, there is a system upgrade prompt.

[The system upgrade takes 5 hours. System functions cannot be used during the upgrade. Please wait patiently. 】

Tier couldn't help but cover her face and smile. This task was just like a joke, and the system didn't give her any room to refuse. There was no other way, so Till could only be "forced" to accept this task. After breakfast, he wandered leisurely in the castle.

To be honest, she didn't know what to do when Tier was suddenly no longer asked to study. She felt bored after walking for a while. After thinking for a while, she walked out of the castle holding her clothes.

The British winter is long and cold. February hangs on the tail of winter, and the wind is still a little bit biting.

Tyr took out his wand and pointed it at the cold wind to give himself an armor protection. This spell is a defensive spell, usually used in duels, but the shield it forms is also good for blocking the wind.

Till's wand was pointed in front of her, so that the invisible shield formed by the armor would always be between her and the cold wind. Till immediately felt a lot warmer - although only a little.

She had no destination, just wandering around casually like she did in the castle just now. She turned a few corners and passed through several small woods. She came to a quiet lake with a thin layer of water on the lake. The ice flakes are almost gone.

"The Great Lake..." Till knew this black lake. It was said that the drainage system of Hogwarts led to this side. Thinking of this, Tier couldn't help but curl his lips, "No wonder the lake is so dark."

"Human, what are you mumbling about?" A strange head with iron-gray skin and long dark green hair emerged from the lake. The sudden sound startled Tiel.

"Who are you!" Till took several steps back and pointed his wand at the head. Now the armor protection was really going to come in handy.

"I am a mermaid, my name is Mercus, the leader of the mermaid community." Seeing that he could talk to Tier freely, the mermaid floated up excitedly, exposing his upper body to the water. "Few humans can communicate with We communicate, and you are the second person I meet!"

The second one, then who is the first one?

"Hello, I am Tilcach Emery, you can call me Tilcach." Bestiality and affinity came in handy. Till did not detect any malice from this female mermaid and hesitated for a moment. Finally, she squatted down by the lake and started talking to the mermaid.

"Do all you mermaids live in the lake?" Till looked at the bottomless lake curiously, "Can you live ashore?"

Merkus shook his tail, causing some ripples on the lake: "We all live in the water, but we can breathe on the surface, but we must return to the bottom within three hours of landing, otherwise our bodies will begin to dry out. Fish tails will also shed their scales.”

Tier frowned: "That must be very painful."

"It does hurt." Merkus hugged himself, showing a scared expression.

When she was a little mermaid, she was curious about her life after landing ashore, but after secretly coming ashore, she was in terrible pain. She struggled to crawl back to the bottom of the lake, and was locked up by her elders for three months without being able to swim freely.

It hurts to think about it.

Just when Tiel was about to speak to comfort her, she saw something dark behind Merkus, but before she could remind Merkus, a huge squid leg wrapped around Merkus.

"Ah!" Till exclaimed, holding the wand and trying to help Merkus, but saw Merkus waving his hand towards her, and then patted the squid's leg affectionately.

Mercus also introduced to Till: "This is my neighbor, a giant squid. We usually call him Pierce. He is very friendly."

"Well, hello, Pierce, you can call me Tierchach." Tier swallowed her saliva. She really didn't know what words to describe what she saw at this time, but she still calmly said to Pierce underwater. greet.

I just don't know if Pierce can hear it.

It turned out that the giant squid could hear Till's words. Till heard its shy voice coming from under the water. Although it was a little unclear, it was indeed greeting her: "Hello, Tilchach, Nice to meet you."

"Let's just say it's very friendly!" Merkus winked at Tier, wagging his tail proudly, and the waves on the water became even bigger.
