Because of his previous experience with Hermione's parents, going to Cho's house was much smoother than expected.
Her mother works at the Ministry of Magic, so she knows Lucas Grindelwald well, because of this her parents were very restrained.
They behaved like they were the subordinates meeting their boss.
Their positions were completely reversed, but the result was good and the two ended up wishing their daughter well.
Cho, who is about to start her fourth year of school, is now a big girl.
When Lucas left her house, the sun was about to set but he didn't go back to the manor.
Instead, he tore the void and went to the cave.
The smell of the sea, the sound of the rough waves and the greeting came to Lucas' ears together.
"Master!"
Since finding the Cliff where the horcrux cave was, about a dozen or so members of the Saints Group were watching over the surrounding area to prevent outsiders from entering it.
"Thank you for your hard work."
Hearing the words of thanks in a gentle tone made these members very excited, even the tiredness of the day was swept away.
Led by one of them, Lucas came to the entrance of the cave where the Horcrux was stored.
It was a crack on the cliff, and endless sea water was pouring into it.
"The two of you go in with me, and the others continue to stay outside."
The ones who were pointed seemed agitated.
Seeing that Lucas entered the sea, the two hurriedly followed.
In this season, the sea water will still bring a biting chill to people.
It didn't take long for Lucas to enter a dark passage.
The passage was pitch black and you couldn't even see your nose, Lucas waved his hand and used the improved "Lumos Stella".
The bright lights of the stars extended to the end of the passage.
With the light Lucas carefully observed the appearance of the dark passage in front of him.
The passage slopes downward, because it is close to the sea, and the air is abnormally humid.
All the way down, Lucas was occasionally hit by a drop of water falling from above his head.
This situation continued for several minutes until a rock wall appeared in front of Lucas.
"Master, traces of magic have been detected coming from here, we dare not touch it casually, and we don't know what will happen next."
Lucas nodded slightly.
He fixed his eyes on the rock wall, and then drew his wand.
Accompanied by a white light from the wand, immediately a White arch appeared on the rock wall.
The arch exudes a bright light, which is extremely dazzling in such a dim environment.
"It really is right here."
As soon as the words fell, the arch emitting white light disappeared.
Lucas knew that the real passage needed blood to open.
Two members of the Saints heard his words and took the initiative to step forward and cut their palm.
Once the protruding rocks on the wall turned bright red, Lucas stopped the two of them.
"Okay, you guys go back and have a good rest, the following part will be enough for me alone, thank you for your hard work."
His wand slid across the palms of the two and their wounds healed immediately.
It's just that the two who lost a lot of blood looked very weak.
Waiting until the two returned to the cliff, Lucas waved his wand again.
The arch appeared again, and the blood on the rock was gradually absorbed by the arch.
When the arch finished absorbing the last drop of blood, a dark passage appeared inside the door.
This is the correct way to the Horcrux storage place.
Lucas held his wand and walked in without hesitation.
In the blink of an eye Lucas was standing by a lake.
He was pretty sure he was in the belly of the mountain, but what appeared in front of him was the dark lake.
"Lumos!"
The wand glows with a white light, but this light can only illuminate a range of one meter near Lucas and it was still pitch black all around.
It was as if something in the cave was absorbing the light.
Lucas stood there without moving a step, looking at the shining green light in the distance.
He knew that was where the fake Horcrux was kept.
"Wingardium Leviosa"
A fist-sized stone floated from the ground.
"Waddiwasi"
The stone broke through the air and flew rapidly towards the direction of the green light.
Suddenly there was the sound of splashes on the calm lake and something seemed to jump out of the water.
Having verified that this place is really as dangerous as described in the original work, Lucas turned and searched along the lake again.
After a while, he found the hidden chain.
Voldemort seemed to think that no one would find the chained boat, so he didn't deliberately hide the magic breath on the chains. Or maybe he wanted people to find it, considering all the traps lying ahead.
When the boat surfaced, Lucas immediately jumped on it and the boat drifted slowly towards the center of the lake.
During the way, Lucas clearly saw the white corpses at the bottom of the lake with the light from the tip of the wand.
These are Voldemort's most proud works, Inferi Army.
Lucas didn't know how many Inferi there were at the bottom of the lake.
But he can be sure that the number seen so far should be quite a lot. Just thinking about all the humans that Voldemort must have killed to make this army would make normal people shudder.
The boat continued to move slowly across the lake. A few minutes later, the bow of the ship seemed to hit something and made a bang as the boat stopped.
Lucas stepped onto the small island in the middle of the lake which was formed from a single piece of Black rock.
The rock is roughly the size of the Hogwarts headmaster's office.
There is nothing superfluous on the small island in the middle of the lake, except for the stone basin emitting green light in the middle.
The stone basin is similar to a Pensieve, except that it is connected to the base below.
There is some emerald green liquid in the basin with a seashell on the side to drink it.
It looked quite nice actually.
But Lucas knows that this is not water, but a strong poison that can make life worse than death.
Whether it is Regulus Black in the original book, or later Harry and Dumbledore.
They all chose to drink the poison into their stomachs.
Lucas couldn't figure it out at first, but after checking it for a while he seemed to understand why Dumbledore and others would do that.
Lucas raised his wand again, and used the Vanishing Charm, Shattering Curse and Transfiguration one after another.
But the stone basin has not changed at all and the emerald green liquid in the basin didn't even make a ripple.
"What kind of spell did Voldemort use to protect this stone platform so well?"
Lucas was just too curious.
If he wants to take out the locket inside, it's very simple for him, but doing so would break the spell on the stone basin.
And he intends to study the spell slowly first, anyway, he has plenty of time.
Until nearly two hours passed, only then did he thoroughly study the black magic used.
In short, what Voldemort cast on the stone basin was not a spell.
Instead, multiple spells were superimposed on each other, and these spells complement each other and are entangled together as if they were carefully weaved.
To break these spells you must know the order in which the spells were cast.
Undoubtedly, it was even more difficult, and they were spells placed by Voldemort himself.
There is no one in the world except himself who will ever know the correct order to cast the spells.
After figuring out what's going on, Lucas stretched his arm and closed his fist as if grabbing something. A moment later the sword of Gryffindor appeared in his palm.
No matter how powerful these spells are, it's still magic.
And Lucas, who has anti-magic, can destroy the magic on the stone with just a light sword.
A thin layer of black anti-magic power ignited on Gryffindor's sword. Then Lucas raised the sword with one hand and swung it downward diagonally.
The sharp blade cut the stone basin and base, making the emerald green liquid spill to the ground and Regulus' Locket appear at the bottom of the Stone Basin.
The locket is small, without the delicate pattern and "S" mark that Slytherin's has on the surface, but it is still priceless in the eyes of some people.
Lucas took out the locket and easily opened it.
Looking at the tight parchment inside the locket, he took it out and unfolded it.
Regulus Black, the last last words in his life appeared before his eyes.
"Regulus Arcturus Black!"
He was reciting the other party's name in a low voice, and there was also the sound of the lake rolling in his ears.
When the locket is taken away, the sleeping corpses at the bottom of the lake will wake up one after another.
If the person who took the locket was not Voldemort these dangerous creatures will launch a fierce attack.
Regulus was dragged into the bottom of the lake by these inferis after drinking the poison.
Lucas put away his wand.
The Gryffindor sword in the left hand and the goblin sword in the right hand are quietly waiting for them to appear.
He had promised Kreacher and Mrs. Back to bring Regulus' body back.
"Kreacher!"
~Pop!~
With a soft popping sound, the old house-elf appeared beside Lucas.
Seeing familiar surroundings, bad memories immediately occupied Kreacher's mind.
"No, no, why did you call Kreacher here? Kreacher is useless, he failed to complete good master Regulus' final order."
His tears flowed down his face and his eyes were full of self-blame.
"Don't cry Kreacher, stand here and watch, we need to find your master's body, and then we will take him home."
"Master?" Kreacher glanced at the elf beside him and thinking of the agreement between the two, his eyes became firmer.
"Kreacher wants to take the good master home!"
At the same time the first batch of inferis had climbed out of the water and came to the stone platform.
Lucas clenched his two swords tightly, ready to try the power of elf combat skills first, and at the same time find Regulus' whereabouts.
