In Tang Ya's bedroom.
After studying it for about half an hour, Jiang Mu finally figured out what the extracted Essence Blood was for.
First, there was the second type of Essence Blood.
It was relatively rare and could trigger Martial Soul Evolution or slightly improve a Martial Soul's quality, though it was chance-based.
Of course, it did not work for every attribute. It mainly applied to Martial Souls focused on offense and defense.
The first type of Essence Blood was the most ordinary kind, but it had many uses and contained powerful life energy.
It could be used for escape secret arts attached to cultivation techniques or for Essence Blood attacks.
Its exact power depended on the strength of the Essence Blood's owner.
"It counts as another lifesaving trump card. There isn't much Essence Blood, but a few instant attacks from a Soul Elder should still be decent."
Jiang Mu nodded. Its usefulness could be considered enormous.
Wouldn't it be a little unreasonable not to stockpile more?
Jiang Mu turned his gaze back to the list. There were quite a few enemies, so he did not hesitate to open the information on Bei Bei, the stall owner, and several other nameless passersby.
Then he began drawing blood.
Meanwhile, the same process was taking place inside a carriage.
"Ahhh!"
Bei Bei was not like Xu Sanshi. Xu Sanshi specialized in defense, so he was far tougher than Bei Bei and naturally had a much higher tolerance for pain.
Bei Bei was in an exceptionally miserable state. In an instant, his face went pale, his eyes rolled back, and the corners of his mouth twitched.
It was as though someone had grabbed his heart in their hand. He had trouble breathing and could not speak, his face white to the extreme. His legs trembled, and though he had been talking just moments ago, he now collapsed to the floor and writhed.
Huo Yuhao, who was sitting opposite him, was startled as well.
"B-Bei Bei, what's wrong with you?"
"Pain... pain!"
His mouth twitched. The intense pain made foam spill from his lips, and he could only respond in incoherent babble.
Although Huo Yuhao did not understand what was happening, he was not overly panicked. Instead, he carefully examined Bei Bei, looking nothing like the timid and fearful Huo Yuhao he had once been.
Another half hour passed, and this time, two targets were opened at once.
After testing two Soul Elders, Jiang Mu seemed to have discovered something.
A Soul Elder could have roughly eight drops of Essence Blood extracted, while that stall owner had only two drops!
That was probably how it worked. Bei Bei had lost two drops of Golden Holy Dragon Essence Blood and six drops of ordinary Essence Blood.
The stall owner had only provided ordinary blood.
However, when he looked at the list, he discovered that Bei Bei's already grayed-out health had also been extracted.
Bei Bei had always been different, yet the amount extracted was surprisingly the same.
After researching it again, Jiang Mu discovered that the gray range of the Revenge List could be adjusted. Overall, the retaliatory range was merely a reminder provided by the system. Whether he listened to it or not was up to him.
Or, put another way, it was more like a setting meant to prevent him from killing someone through excessive torment.
Something like a safeguard against exceeding a particular value.
It was currently set to stop automatically at ninety, which was why Bei Bei and Xu Sanshi had yielded exactly the same amount of Essence Blood. Though there was a high chance not even a drop of blood could be squeezed from the other's heart anymore.
Once he understood it, the corners of Jiang Mu's lips curled upward slightly.
"As expected of a system with such twisted tastes. But I like it."
[Revenge List [Tang San, Sea God, Asura God, killing intent index: 90%, retaliatory range...] [Xiao Wu, Asura Scabbard, killing intent index: 10%, retaliatory range...] [Xu Sanshi, Soul Elder, killing intent index: 90%,...] [Bei Bei, Soul Elder, killing intent index: 85%,...] [Wang Dong'er, Soul Elder, killing intent index: 35% (current killing intent: 10%),]
After looking over it, there were still too few people on the list.
His means of self-preservation were not sufficient enough.
Just as he stared blankly at the list.
Click!
The door suddenly opened.
Tap, tap, tap!
Two sets of footsteps rang out at once. When Jiang Mu came back to his senses, he saw only a graceful figure rushing toward him.
Although Jiang Nannan did not use teleportation, she was almost as fast as if she had. Her long, fair legs carried her before him in an instant.
The fragrance from her body washed over Jiang Mu's face. Before he could ask anything, she grabbed his arm.
"Little Mu, we're back. Are you still feeling unwell?"
"No, I'm much better now."
A smile appeared on Jiang Mu's face. He truly felt far better now.
Could the Heavenly Secrets Stone, the rule-based item rewarded by the system, prevent any major method from discovering the three of them?
That was another means of self-preservation. He could use precise attacks, and after researching it further, perhaps he could give Jiang Nannan another lifesaving trump card as well.
"Phew, you scared me to death. It's good that you're fine."
Though Jiang Nannan had let out a sigh of relief, she still pulled Jiang Mu directly into her embrace.
"Mmff..."
His mouth was pressed against her, and he felt as though the air around him had grown somewhat scorching.
Seeing the way the siblings interacted, Tang Ya could not help revealing an envious expression.
But after her envy faded, her eyes subconsciously glanced to the side, and she suddenly spotted several pieces of clothing scattered across the bed.
Purple triangles, blue-and-white stripes, all kinds of styles.
Boom!
Tang Ya's face instantly turned red as if it had been blasted by a bomb.
Biting her lip with her pearly teeth, she secretly glanced toward Jiang Nannan and Jiang Mu. Only after seeing that neither of them was looking at her did she breathe a sigh of relief.
She tiptoed over there.
Whoosh, whoosh, whoosh!
Her hands moved so quickly that only afterimages remained as she tossed everything beneath the blanket.
"Phew..."
She let out a breath, raised a hand to smooth her long hair behind her, and once her expression gradually returned to normal, she sat by the bed and watched the two of them.
Jiang Mu and Jiang Nannan turned their heads at the same time and happened to meet her gaze. Tang Ya felt somewhat embarrassed, her eyes darting away as she did not dare look Jiang Mu in the eye.
After all, having her underwear seen was still rather embarrassing.
Not to mention that she harbored a tiny bit of affection for Jiang Mu.
Jiang Nannan, however, thought Tang Ya was sick and asked curiously, "Uh, Tang Ya, what's wrong? Your face is so red. Are you sick too?"
"I'm fine. I just got a little hot from running earlier."
After forcing herself to maintain her expression, Tang Ya raised a hand and lightly fanned herself, showing that she had not been lying.
"Oh..."
Jiang Nannan did not pursue the matter. She withdrew her gaze and looked back at Jiang Mu.
"Little Mu, this is the spatial ring I bought for you. Use the larger one. I'll use the smaller one. They're one cubic meter and 0.8 cubic meters."
"Then thank you, Nannan."
Jiang Mu did not refuse and accepted it directly. To him, whether he used a Soul Tool or not made no difference, since he had the System Space. Still, having one was not bad. At the very least, it could help conceal things.
It was not that he wanted to hide it from his sister, Jiang Nannan, but this sort of thing was not easy to explain.
And even if he told her in the end, it would be difficult to explain properly. He would bury it for now. The time was not right yet.
"By the way, are you really siblings, or what exactly is your relationship?"
Tang Ya was very curious about how they addressed each other. After all, she had seen quite a few people doing cosplay, and she had heard it could heighten the excitement during the process.
So she was somewhat suspicious because of the way the two before her interacted.
Her eyes were full of anticipation, as though she wanted to hear the answer she wished to know.
Jiang Mu was briefly stunned when he heard that, then turned and said, "Oh, you're asking about that."
