Honkai: It’s broken, I have become the Herrscher of Corrosion?

"Haha... finally appeared... Fu Hua, is this the place you were talking about?"

Fu Hua shook her head:

"No, not yet. The real secret is on the bottom floor. You still need to keep going forward..."

Fu Hua's eyes swept across the equipment in front of her. After a few seconds of pause, her expression changed subtly:

"Wait a minute, these instruments... I recognize these symbols... I take back what I said before, the things on this floor are also very important to you, explore them carefully, and you must find them..."

Before Fu Hua could finish her words, her body once again turned into countless rays of light and dissipated, just like before.

"Hey!"

Ji Zi was feeling curious and surprised about the scene in front of her, and Tesla's sudden loud voice really scared her.

"What happened to you just now? You were staring blankly ahead, and you didn't respond when I called you."

"A person... in a daze... Tesla can't see it... What on earth is going on?"

"Oh never mind, let's take a look at the records I found. As an A-rank Valkyrie, you must be more familiar with Destiny than I am."

[——Record number, TBOS-2000-0106]

[It succeeded, although some accidents occurred. But the Herrscher Killer has fully proved his worth in the second collapse. Cecilia's blood has undoubtedly reached a very high degree of completion. I am only one step away from completing the Saniate Holy Blood.]

There was no doubt that this was Otto's voice. But Jizi was very unfamiliar with the experiments conducted by the bishop, and even heard the term "Sacred Blood of Shaniat" for the first time.

"Cecilia... is she the former S-rank Valkyrie Cecilia Shaniat of Destiny? She is not..."

Tesla nodded seriously:

"Yes, Cecilia died in the second Honkai 17 years ago. In order to prevent the Herrscher from going berserk and causing disasters, she used her blood to neutralize the Honkai energy. She was a brave and great person... Wait, her blood neutralized the Honkai energy?"

Tesla thought of something and continued reading.

【——Record number: TBOS-2014-0007】

[Why? It's already been 14 years, but there's still no progress in the research of the Holy Blood. It's just the last step... No, am I just too impatient? I've even waited 500 years...]

"Hmm...it seems that Otto's research has reached a bottleneck."

【System prompts: ■■■■, ■■■■■■, ■■■……】

"what happened?"

Tesla waved his hand:

"piece of cake."

After a while, the original abnormal record reappeared in front of the two.

[——Record number. TBOS-HV-0001]

[Dr. Maki is such a genius! The HSN-B46 serum he designed can actually inactivate the Honkai energy in living organisms and release it through the body's circulation.]

[His original intention was to treat the Valkyries, but I saw the true value of the serum at a glance. It is the "final step" to complete the Holy Blood that I have been looking for.]

[Alas, what a pity... the doctor is no longer alive, otherwise I would really like to invite him to celebrate with me.]

"Maki…Doctor?"

Hearing the unfamiliar name, Tesla subconsciously looked at Ji Zi beside him, but found that she was just as confused and puzzled as he was.

[——Record number. TBOS-HV-0538]

[After mixing HSN-B032 serum into the holy blood sample using the ratio obtained by the formula (HSN-f-46), the solution turns bright red.]

[Experimental records, first experiment: The three groups of test subjects were ordinary human females, C-level Valkyries, and infected female dead soldiers. All were 18 years old, and their height, weight, and various vital parameters were within the human standard range.]

[After the injection, ordinary human women did not show any abnormality. However, the C-rank Valkyries lost the Honkai control they had gained through transformation.]

[But the most interesting is the third group... The dead soldiers began to show symptoms of pain and rampage, and a few individuals lost consciousness. Among those who lost consciousness, weak brain waves were detected again. In order to confirm the hypothesis, more experiments are needed. Unfortunately, the production of HSN-B46 serum requires a lot of resources, which seriously slowed down the speed of the experiment. ]

"Is this the end? Damn it! You should finish writing it all at once. What are the results of the experiment?"

Tesla's mood at this moment was like a student facing a difficult problem. He had no idea how to start. He finally got the reference answer, but there was only one word: omitted.

"There is only one record left, you must give me something useful!"

[——Record number. ■■■■—■■—■■■■]

[Hahahahahahahahahahahaha…]

Hearing Otto's hearty and devilish laughter, it was like three golds in a row. Tesla and Ji Zi were both startled.

"What on earth is going on with this record?"

[Oh, good, I succeeded! ]

[After being injected with the mixture of holy blood and serum, the Emperor-level Honkai Beast began to weaken at a speed visible to the naked eye. At the same time, the Honkai energy in its body began to escape the control of the main body. In the end, the Emperor-level Honkai Beast, which was composed only of Honkai energy, turned into ashes in an instant. ]

[Finally completed, this is humanity's god-killing gun! ]

[Everything is ready. K423 has entered St. Freya Academy as planned. The spies have also been arranged. And now... the God-killing Spear is in my hands.]

[Then, it’s time to wait for the harvest...]

After all the recordings were played, Tesla looked at Ji Zi hesitantly, wanting to say something, but there had to be a beginning to the words. Just as she was hesitating, Ji Zi spoke first:

"The God-killing Spear... can it be made now?"

Ji Zi stretched out her right hand, which tightly held a tube of red serum. At the other end of the test tube, the letters HSN-B46 were clearly written.

"I think... now is the time to put it to use."

Samples of the holy blood are available on this floor of the laboratory; all they lack is this scarce serum.

'You... better not hold out too much hope. The amount of serum in this tube is too small. I only have one chance to try.'

"That is to say, there is still a possibility of success."

Ji Zi stuffed the serum into Tesla's hand and turned her back.

"In order to improve efficiency, I will go to the next level to explore. I will give this medicine to you!"

"Wait a moment!"

Tesla called out to Ji Zi who was about to leave and threw a mechanical device over to her.

"This is……"

"I just found the spare parts for the Valkyrie armor. You've been hacking your way here, so your equipment must have been torn to pieces. Go quickly, but don't die in there, or I won't have the time to get you out."

"Oh, don't worry."

After Ji Zi simply repaired the armor, she turned around and left in a cool manner.

After confirming that Ji Zi had gone down, Dr. Tesla began the experiment. She put on gloves and picked up a syringe filled with purple liquid.

"It is now 15:44. The sample has been prepared according to the steps, and the next step is to enter the testing phase."

After she finished speaking, she injected the solution in the syringe into her arm in one breath.
