Bloodline Mystery and Fusion Limit!

If not, Ivan can hardly imagine how Tom found the entrance to the Chamber of Secrets,

The entrance to the Chamber of Secrets was located in the girls' bathroom, which was used regularly until Myrtle's death.

Without proper guidance, Tom Riddle had no reason to sneak into the girls' bathroom and find the snake carved into the copper dragon's head.

Unless he had a penchant for peeping into girls' toilets…

[Ding, mission "Bloodline Mystery", progress updated…]

Ivan's thoughts were interrupted by a sudden system prompt.

Ivan opened the mission log and found that the mission for Bloodline Mystery was nearing eighty percent completion.

It seems that what he is looking for is in this room…

Ivan put down the torn page and went to a table in front of him, which was littered with odds and ends and sheepskin scrolls.

The words on the nearest parchment were blurred, and Ivan was able to make them out.

The title read Fusion Plan Number Twelve…Failed!

The title was also circled to indicate the reason for the failure, that the black stone powder was in conflict with the moonstone and that Mandrake should not be added…

In addition, Ivan found a small line of text at the bottom, which stated that the higher the compatibility of the magical creature chosen for the ritual, the higher the success rate of the blood fusion, and the lower the success rate if it were not…

"I can't believe that's what happened," Ivan muttered to himself, feeling a pang of fear.

He did not know that there was such a thing when he fused with the blood of a unicorn, so he blindly performed the first blood fusion without confirming the level of compatibility.

Yvonne marveled at her good fortune at having been able to pull this off. The unicorn she had chosen seemed to fit her perfectly.

After reading the parchment, Ivan's curiosity was piqued. He pulled out a dusty chair, cleaned it, and sat at the table to examine the rest of the parchment.

It is unknown if some special magic was placed on them, but they were able to make out the general contents of the writings over the millennia.

Most of them recorded the development of the Bloodline Fusion Potion, and there were dozens of proposals on the parchment table.

Each was tested with a special potion ingredient as the core,

Despite the few failed summaries at the end, Ivan can only imagine the effort Salazar Slytherin must have put into learning these lessons.

Five of these dozens of proposals were approved by Slytherin.

However, most of the recipes were for one creature, and only the last one, which used Hemolytic Grass as the core, was suitable for all magical creatures…

"Whew…" Ivan muttered, exhaling. "Is that what Precursors mean?"

Ivan finally understood why Salazar Slytherin claimed to be a great pioneer.

Slytherin may not have been the first wizard or witch to study blood integration, but it is likely that he was the most thoroughly researched wizard or witch of his time.

Crucially, Salazar Slytherin's ambition went beyond that, after creating a Merge Potion that could fuse all bloodlines.

The remainder of the parchment was devoted to a different subject: the method of merging various bloodlines.

Some potions have even been modified, but they have never been able to solve the conflict caused by the integration of multiple bloodlines.

As a result, Salazar Slytherin used the sheepskin scroll to remind his heirs not to try anything unless they had a solution to the conflict.

Slytherin also made a wild guess based on previous Merge experiments.

Even if a wizard could fuse multiple bloodlines, there was bound to be an upper limit.

And this maximum limit was most likely… seven!

It took Ivan several hours to go through the information.

It must be noted that Salazar Slytherin, despite being a bit of a narcissist, often used the adjective "great" as an adjective when he opened a door.

However, this research alone was worthy of his usual boasting.

Ivan put down the last chapter of the parchment, and two system prompts sounded in his head.

[Ding, after a period of study, your Potions proficiency has increased significantly, reaching Level 4 first (1512/1600)]

…

[Ding, quest "Bloodline Mystery", new progress…]

Objective: Find a way to fuse multiple bloodlines

Current Task Progress: 100%

Task Reward: Legendary Points*1 (unlocked)

…

…

Ivan was not surprised to see the system prompt.

After seeing Slytherin's potion-making progress through the parchment, Ivan felt he had learned a lot, and his potion-making skills had improved.

Not to mention the mission of completing the Bloodline Mystery, which was why he had come.

Ivan was delighted when he saw that his Legendary Points had reached four. All he had to do was gather the last of them, brew the Fusion Potion, and attempt to fuse the second bloodline.

This meant that his strength would once again rise substantially.

As for the magical creature that had fused their blood, Ivan had decided that it would be the Basilisk outside the door!

Since Salazar Slytherin speculated that there was a limit to how much blood a wizard could fuse, Ivan, of course, wanted to fuse a few of the finest creatures!

The basilisk was undoubtedly one of them, and its ability to die straight from the snake's eye was extremely tempting to Ivan. If he was lucky enough to inherit the basilisk's ability, he would be able to stare anyone to death.

Thinking of this, Ivan suddenly felt that the Basilisk outside the door was not so ferocious and terrifying, but strangely kind…

Slytherin was so kind to his heirs that he offered them a way to integrate them, and kept the most suitable magical creature, the Basilisk, there.

After all, only Parseltongue and Basilisk blood could open the door.

He was, of course, an exception to this rule, as he had learned to speak Parseltongue through the experience card, but with the protection of the system, his compatibility requirements were not as high.

Ivan sorted through the documents, sorted them, and left the Slytherin research lab. The two guards at the door closed the door automatically, and the sword crossed itself again.

"Hsss ~ (Eight-Eyed Spider… eating…)" The basilisk dragged its massive body around Ivan, hissing as it circled him…

Ivan had learned of the Basilisk's origins and duties from the parchment, and knew that it could not be harmed without orders, so he was not afraid of it, and ordered it to attack in Serpentish.

"Hiss ~ (Now, show me out…)"
