Sirius cast a bubble head spell on himself and Kreacher, and was about to jump into the lake, when he suddenly asked in a sullen voice, "Kaka, are these Yin Corpses going to attack me underwater?"

Calvin looked up at the incandescent fire dragon, then at all the yin corpses hidden in the lake, and said with certainty, "No, the light of the fire dragon is enough to make them uncomfortable, don't worry."

With Calvin's assurance, Kreacher eagerly jumped into the lake, and Sirius tossed his coat aside, revealing his thin body, and jumped with him.

As soon as Sirius stepped out of the water, he felt the freezing cold of the lake, and he shivered a little, but quickly adapted to the cold—a far cry from the dementors' coldness.

Sirius then began to look around the water, pulling over a corpse hiding in the shadows, breaking its hands covering its eyes, and tossing him aside after seeing it. As Calvin had expected, none of the corpses had made a move on him.

"What a powerful fire dragon." Sirius muttered in the bubble that the Yin Corps was afraid of light, but ordinary light could not make the Yin Corps fear to this extent.

Calvin walked over to the side of the ship and studied the ship as usual to see if there was any magic left on the ship. Calvin examined it closely and found that there was no offensive or interfering magic on the ship, only one soul-related magic.

This intrigued Calvin, and after a little pondering, he understood the function of this magic - to detect the weight of souls, so that the ship could only carry two souls, so if you want to get the Horcruxes, you must bring a victim.

Voldemort's study of the soul is probably no less than that of Salazar Slytherin. Calvin thought

Calvin tentatively boarded the boat, and after making sure that there was nothing out of the ordinary, he picked up the boat pole and headed for the island in the middle of the lake.

"A bit like Charon, the boatman of the River Styx, carrying another soul to death." Calvin thought for no reason.

Very open, Calvin stepped onto the island in the middle of the lake, and began to observe the stone basin in the center of the island, and the green potion in the stone basin.

This is the last device Voldemort used to protect his Horcrux, and I don't know how much strength he used.

Calvin did not rashly touch the stone basin and the potion, but used his right hand to poke out a slightly silver magic filament, and gradually probed from the bottom of the stone platform upwards.

After all the investigations were completed, Calvin once again lamented that Voldemort was really a genius who came up with the idea of using a confinement charm on liquids, and even succeeded in combining the imprisoning charm with the fluidity of liquids.

Calvin took out a pair of dragonskin gloves and put them on, and put his hand into the potion. He easily lowered his hand under the water, but after only one knuckle penetrated, he could no longer reach for it.

"It's kind of interesting..."

Calvin took the chain-fastened shells around the basin as a spoon and placed it in the basin. This time the magic didn't stop him, and the shell smoothly scooped a spoonful of potion out of the basin. Calvin took a closer look at the shell and the potion inside, ready to pour the potion on the ground.

The emerald green water formed by the potion did not pour smoothly on the ground, but formed an eerie arc and flowed back into the stone basin. ….

Calvin raised his eyebrows, propped his hands on the stone basin, and looked at the pot of potions in front of him, "Do you have to drink it?"

He scooped out another scoop of the potion, intending to analyze the potion's composition - not Scarpine's Manifestation Charm, of course, Voldemort would have prevented it.

After about fifteen minutes, Sirius, who was a little unbearable from the cold, came up from the lake to catch his breath, and saw Calvin take out a small table and place it on the island in the middle of the lake, on which lay a pale green toad with five eyes, and quacked twice.

What did he do with a toad?

Then, Sirius saw Calvin dip his index finger in the potion in the shell, snap his fingers, and a pinch of dragon fire ignited in his fingertips. Dragonfire's colors are complex, with red, blue, and white being common, but a darker shade of black.

The five eyes of the toad on the table were all fixed on the dragon fire at Calvin's fingertips. Soon, the color of the toad changed from pale green to black as deep as Calvin's fingertips

color, the color on the toad's body is constantly changing, and different bands of color appear.

When the color of the toad's body was fixed, it croaked twice. Calvin then extinguished the dragon fire and began to look at the color on the toad's body.

"Light gray, the slime of the Flober caterpillar;

purple, liquid inside unicorn horn;

The sap of the scarlet weed, which can make people impatient and reckless, has a confusing effect;

Light blue, smelling phantom grass, can be used like this;

Seven different shades of green? Voldemort had at least seven snake venoms mixed up;

There is even a color that I have never seen before, and it seems that there is an unknown material."

Sirius, who could no longer understand Calvin's actions, re-dived to the bottom of the lake to find his brother.

Calvin had already analyzed the composition of the potion, took out a piece of parchment and pasted it on the toad's back, rubbed the color down, and then put away the table and the five-eyed toad, and said to himself:

"It seems that the potion works very much like the magic on the stone walls outside, both of which disturb the mind and mind of the person taking it, exacerbate the pain, and create illusions. Ahh

It seems that Voldemort did not want to kill the visitor directly, but used a cat-and-mouse mentality to tease his opponent, and after the visitor's mind was destroyed, he was dragged into the lake by the Yin corpse.

Calvin shook his head, he could probably guess that Voldemort when he left these methods was already arrogant to a certain level, and even thought that these methods could be killed...... Dumbledore.

Of course, it is impossible to kill Dumbledore with these means alone, and at most it will cause him some trouble.

Calvin poured the potion back into the stone basin, and now that he had figured out Voldemort's tricks, there was no need to go on like this.

He flicked his wand slightly, and a large light gray iron feather with a metallic sheen grew from it.

Calvin held the feather above his head with a sword, and then slashed down at the stone basin, only to hear a click, the stone basin was cut off by Calvin with a sword along with the crystal platform underneath and a series of protective magic arranged by Voldemort.

The potion flowed through the split gap, revealing a locket lying at the bottom of the stone basin.

Sirius, who had just been in the water, was startled by this loud noise and resurfaced, and saw Calvin holding a large feather in one hand and a locket from the slightly deformed stone basin with the other.

Sirius was about to ask what was going on, when he heard Kreacher cry out loudly, "Master Regulus!".
