The blood that falls will be verified for authenticity, and those with pure blood will receive treasures.

Salazar Slytherin left this final test in front of his vault, a test that wizards of impure blood simply could not pass.

Unlike courage, perseverance, and wisdom, such a thing as bloodline is innate, and it cannot be changed at all.

Salazar Slytherin wasn't just talking, he was really putting it into action.

He won't leave anything for non-pure-blood wizards, even if you go to great lengths to find the key left by Slytherin and enter his vault, but you won't be able to get Slytherin treasure unless you're not a descendant of him or a wizard of his approved bloodline.

Pureblood, Salazar Slytherin took it to the extreme.

The molten pool in front of Evan and the others is an incomparable magic, it can verify the blood of the people who come here, to determine whether their bloodline meets Salazar Slytherin's requirements, Evan doesn't know what magic Slytherin used, it sounds incredible, maybe it uses the knowledge of potions.

That is, the molten slurry in front of them is actually a specially treated potion.

Furthermore, the underground of Gringotts is actually a huge potion crucible......

The magic was undoubtedly shocking, but it didn't seem impossible for a wizard of Slytherin's calibre to do so.

Everyone knows that Salazar Slytherin is very good at Potions, and in the history of magic, many Potions masters have also graduated from Slytherin House, and it seems that when they were separated, Slytherin students possessed certain qualities that were very suitable for developing in Potions, but Evan did not expect Salazar Slytherin to be good at this.

He is using nature to make potions, using heaven and earth as potion crucibles, boiling magma into potions.

This kind of magic is incredible, even more shocking than when Gryffindor borrowed the power of the stars.

"What the hell is going on?" asked Harry again.

"Harry, the magic that Slytherin left behind was to verify the bloodlines of the wizards who came here to see if their bloodlines met his requirements. Hermione said, observing the lava in front of her behind Aven, "That is, we are going to drip our own blood into the lava, and if we meet Slytherin's requirements, then we may get the treasure he left in this vault, and if we don't meet Slytherin's requirements, then we will be attacked by lava like Evan just did......"

"Can this magma verify blood?" said Harry, turning his head in disbelief, "How did he do it?"

"No one knows, and I'm guessing it's probably a potion in which Slytherin pre-fused the blood of the wizard blood he fancied, and if a certain ingredient in the blood of a latecomer was the same as the pre-infused blood, it would give the treasure, like a special lock. "I don't know which wizarding family Slytherin's pure-bloods we're looking for, but none of our bloods are up to the mark. ”

"Hmph, pure-blood, Malfoy's bloodline definitely meets the requirements. Harry said dismissively.

"So we're not going to get anything?" Elaine asked.

"It should be so, Salazar Slytherin didn't leave us anything in this vault. Evan sighed and said, "Of course, there is another way to get his treasure, and there is no need to verify any blood, but to break this lock and break it directly." ”

But this is impossible, Aven can use the remaining cyclops energy to detonate the lava again, but the treasure hidden inside may also be destroyed, and this is not a sea where there is nothing, once the magma erupts, the Diagon Alley outside will also be destroyed, which is undoubtedly a catastrophe.

When the time comes, Evan will be recorded in the history of magic in another way, destroying the evil dark wizards of Diagon Alley and most of London......

"Can you force your way in?"

"It's simply impossible. Evan shook his head.

"Then what are we doing standing here, let's get out of this place quickly. Elaine said decisively.

She was not interested in the treasure left behind by Slytherin at all, although nominally, all of these things left behind by Slytherin should belong to her.

"Wait, don't rush, you three haven't tried yet. Evan said, hurriedly stopping Elaine as she was about to leave.

"But as you just said, the blood of several of us doesn't meet the requirements. ”

"That's right, the four of us are not purebloods, but there are no real pureblood wizards right now. "Thousands of years have passed, and the bloodlines of any wizard have become very mixed, and from a purely potions point of view, any kind of material can cause changes in potions, and our blood is now the material, and perhaps some of it will satisfy Salazar Slytherin's request that he give us some of the treasure, which is also uncertain." ”

From a potions point of view, the four of them are not at all likely.

Harry and Elaine, in particular, had ancestors who had been wizards thousands of years ago.

There should be some pure-bloods in the two of them, and it depends on whether they can meet Slytherin's requirements.

"I beg for potions!" Elaine muttered.

"Alright, you three give it a try, Hermione, you come first, then Harry and Elaine. Evan said he had Hermione come to him.

The two men huddled at the exit of the secret passage, and as before, Evan slashed Hermione's fingers away with his wand, and a few drops of blood fell into the magma below.

The magma boiled, bubbling like a potion being brewed.

Then with a bang, a pillar of fire shot up into the sky.

It lunged at Evan and Hermione, eventually colliding with Aven's protective magic.

With the boiling heatwave, the magma sputtered in all directions, and this imposing pillar of fire erupted for more than a minute before stopping.

Like Aven, there were no purebloods in Hermione's blood.

Obviously, both of their ancestors were very pure Muggles, or the kind of bloodline that Salazar Slytherin looked down upon.

Hermione was followed by Harry, and as before, Evan scratched his fingers for him.

The blood fell, but the magma pool below was still calm, and there didn't seem to be any special reaction, and there were no pillars of fire rising into the sky.

"What's going on?" asked Harry.

"Well, potions science is supposed to neutralize a part of your blood and a part of the potion in the cauldron. "It didn't cause any change, like a palliative or an enhancer...... That is, your blood does not meet Salazar Slytherin's requirements, but he does not intend to punish you either. ”
