The blood contract is one of the many ways in the Myriad Spirit Sanctuary for two parties to establish a trustworthy cooperative relationship.

Anyone, regardless of race, can sign a blood contract; the only thing required is one's blood and the ability to chant a spell in conjunction with the contract's terms and conditions.

The duration of the contract can be specified, it can be a second or even a lifetime, but the punishment for breach of the contract cannot be specified; whoever breaches the contract has only one fate, and that is death; this is the only reason blood contracts are not widely used; they are too strict. Legend has it that the blood contact is created by a race known as blood demons, and the legitimacy of all blood contracts established across multiple worlds is monitored by the progenitor of blood demons, who is said to be a rank 7 lifeform.

The contract's contents can be updated if parties involved agree, and the contract can also be nulled if the parties involved want to.

"Wait a little longer; you can heal your wounds in the meantime." Fionn addressed the Anomaly.

The Anomaly nodded and sat to the side, closing his eyes as if meditating. Ether, who was sitting next to Fionn, kept a wary eye on the Anomaly, his gaze never leaving him.

Time passed slowly as the three of them sat quietly recovering, Fionn, who was nearing the end of his assimilation of new spirit power, felt the changes within him.

WOOOSH!

Fionn retaracted all of his avatars within his body; as the avatars entered his body, he felt some information enter his head; Fionn was already accustomed to the sensation, so he didn't feel much discomfort.

The first piece of information was about Fionn's AK-47. "Divine judgement lighting, what is that?" Fionn wondered as he went through the information in his head. The information was along the lines, "transformation to Divine judgement lightning (0.01/100) completed."

"Never heard of Divine judgement lightning, but from the sound of it, it appears pretty badass," Fionn thought, unable to identify the name.

Looking at the minute progress, Fionn thought, "Wow, the progress is really lame, I think it would take quite a long time."

The changes to the skysurf board were less vague than those to the AK-47; the recovery speed has increased from 200 percent to 210 percent, and the mana consumption for Void walker has decreased slightly.

"That's a lot more practical," Fionn thought, nodding his head in satisfaction.

Other avatars did not undergo significant changes, so no information about them came to Fionn's mind, but he could speculate that they might undergo some changes in his next spirit increase.

Fionn stood up and stretched his body, having finished his analysis. Looking around, he noticed Ether on guard and the Anomaly recovering, he looked much better now.

The Anomaly, sensing a disturbance in the environment, opened his eyes and asked Fionn, "Are you ready now?"

Fionn nodded and asked, "So, what are the conditions you've considered?"

"Our relationship must be one of equals; I will assist you to the best of my ability whenever you are in danger or in need, and in return, you will help me grow stronger." The Anomaly stated.

"What is the extent of your assistance, and how long will the contract last?" Fionn inquired.

"The extent of my assistance is determined by the benefits to be gained; if the thing I'm fighting for affects my growth, I won't mind risking my life; if it's something trivial, I won't endanger my life; and as for the duration, let's start with 50 years." The Anomaly responded straightforwardly.

Fifty years is not a long year for those who practise mana, especially for races such as the Pishacha, who live for thousands of years; fifty years are like fleeting clouds.

"Fair enough," Fionn said after a brief pause, then added "but I'd like to add one more condition, i.e that you cannot take any action that will adversely affect my well-being without my consent, and the same goes for me; if you agree to this, we'll can establish the contract right away."

After a brief moment of thought, the Anomaly said, "OK, I agree."
