HP: After binding to the strongest wizard development system

"Do you know about the Blood Pact?" Till showed a kind smile to Voldemort, and the smile even reached his eyes. "You have it, but it is an improved and one-sided one."

The first time Thiel learned about the Blood Pact was through the mouth of Grindelwald. He rambled on about his past with Professor Dumbledore. Grindelwald recalled it bit by bit, as if he was worried that he had forgotten it. Things that happened when I was young, so I speak very slowly.

Fortunately, Till was patient and had a good memory, so she remembered everything Grindelwald said.

The so-called Blood Pact, Grindelwald believes that it is a two-way binding curse. Once one party violates the rules of the Blood Pact and becomes hostile and murderous towards the other party, the Blood Pact will punish him.

It's just that this curse has materialized and its binding force is stronger.

The blood alliance between Grindelwald and Professor Dumbledore has long been broken. Grindelwald did not elaborate on this sad incident, but judging from those few words, he should still be with Tire's old friend, the expert on magical animals. About Newt.

After the blood pact was broken, Grindelwald was voluntarily imprisoned at the highest point of Nurmengard until the arrival of Lupine and Tyr, reviving Grindelwald's aging heart.

The unilateral blood alliance that Till used on Voldemort was actually Grindelwald's idea. He had already used it on Professor Dumbledore, one night when he "passed by" Hogwarts.

He cut his palm and let the blood drip on the corridor of Hogwarts. Professor Dumbledore did not know that this was the blood pact between Grindelwald and him once again.

Although this blood pact only works for Professor Dumbledore - once Professor Dumbledore wants to kill Grindelwald, he will feel pain.

This is Grindelwald's revenge on Professor Dumbledore, and it is also the guarantee for him to walk in front of Professor Dumbledore and cooperate with Tyr.

And Grindelwald has been in a good mood after concluding the blood pact, because Professor Dumbledore still doesn't know that there is a new layer of blood pact between him and Grindelwald.

This means that Professor Dumbledore never thought about killing Grindelwald in countless meetings after that.

This is Grindelwald's happiest fact.

Till also wanted to put a layer of restraint on Voldemort, but the tricks Grindelwald used on Professor Dumbledore were obviously not suitable for use on Voldemort. Therefore, Till just added his own blood to the bottle of rebirth potion that Voldemort drank. and magic power, unilaterally concluded a simple version of the blood alliance.

Voldemort will not feel pain because of his intention to kill Till. He will only gradually lose control of the magic in his body during several duels with Till.

The more attacks he made at Tyr, the more his magic became out of his control.

Grindelwald passed quietly behind Till. Of course he came to join in the fun on such an important day: "I'm really a genius, right?"

"Who says not?" Till and Grindelwald exchanged a look, and Burgess Emery smiled behind Till.

It was the only one present who knew the truth. This blood alliance or it watched Till experiment countless times in the practice room to make sure it would not backfire on Till himself before adding it to the rebirth potion.

Voldemort's hand holding the wand was trembling slightly. He really could no longer control the magic in his body. This was a long-lost feeling of loss of control. It made Voldemort even crazier than when he split his soul and made a Horcrux!

A madness that would lead to his failure? Voldemort looked up to the sky and laughed, completely unaware that many Death Eaters around him had silently left and defected. In other words, the moment he knew about the existence of the Blood Alliance, he had no time to care about those outsiders.

Bellatrix wanted to help her master, but was kicked to the ground by Voldemort. Voldemort could only see Till now: "Do you think losing control of your magic power can stop me from killing you?"

Voldemort's arms were trembling, but he was still able to issue several killing curses. Tyr and the three of them were walking in a green light inseparable. Tyr also counterattacked at any time. The killing curse that frightened the wizards was now useless. Galleons the same.

Till and Voldemort never considered using other spells from the beginning. They just wanted to take each other's life with one blow.

"Is this all your strength? Tom Riddle?" Teal said wantonly the name that Voldemort regarded as a shame, or rather the surname - the title given to him by his father, Riddle.

Voldemort roared: "Shut up!"

"Are you kidding me? You have no right to order me!" Till rushed out of the surrounding attacking circle, leaving behind Snape and Burgess Emery. She had a hunch that Voldemort was going to make some dangerous moves, and Till chose to face him alone.

"Tyr!" Snape and Burgess Emery had never been so in sync, but they were directly surrounded by Voldemort's remaining loyalists. Burgess Emery burst out with all his magic, and only There was just enough time to see a person fly out in the huge collision of magic power.

Burgess Emery subconsciously caught it, but without looking at him, he threw it to an open space. Not its host, Burgess Emery had no interest in paying much attention to this annoying creature.

What about its host? Teal——

【Host? Host? Host! 】The smoke and dust blown up in front of him formed a thick fog-like visual obstruction, and the magic power of the explosion surrounded the center of the magic collision. Burgess Emery could not pass through. Although the system's scan could scan out Nerytil's Vital signs, but Till never responded to its call, which made Burgess Emery finally realize what it was like to be afraid.

After the magic collision made a big noise, except for a few loyal servants of Voldemort such as Bellatrix, everyone else stopped. Hogwarts also reduced the number of attacking personnel, and more people started Gather towards the castle to prevent any accidents from happening.

The so-called accident is nothing more than that between Till and Voldemort, the latter won. Without Tyr, a powerful wizard who was fighting against Voldemort at the front and acting as the backbone, Voldemort and his Death Eaters could easily pass through their siege and reach the castle.

Although they didn't want this possibility to happen, Till had told them in advance to be fully prepared when the situation was unknown.

Till seemed to have expected this to happen.

Snape was one step behind Burgess Emery, but he was more decisive than Burgess Emery. The whole process was calculated. Burgess Emery would weigh the pros and cons and stop when he knew it was impossible to get through the magic circle. Snape would not.

He only knew that his lover was alive and dead, and she was in the smoke and dust in front of him.

Because of this, when the magic prevented Snape from moving forward, Snape gritted his teeth and kept walking, with traces of scars on his body. He was even more embarrassed than when he faced multiple Death Eaters just now.
