Yale sighed after reading the description because with his current level he couldn't use that Legacy Skill for even a minute. Yale's legacy bloodlines helped the Sword Law and Time Law, but Yale had yet to obtain the Space Bloodline, so he lacked a lot into the Space Law part.
In fact, Yale didn't know anything about the Sword Law, so it was worse than the Space Law if one didn't take into account the effects of the Sword Bloodline, but the Sword Essence was on a superior level than the Sword Law and the understanding about the Sword Essence could be used as a replacement.
The Space-time Sword Formation was a fearsome formation because the swords attacking inside would be almost impossible to block unless the target also had some control over the space-time.
However, powerful people wouldn't die in less than a minute even if those swords attacked them non-stop. Moreover, as it needed the Space-time Judgment Sword as the core, Yale couldn't just flee after creating the formation. In fact, the formation needed to be actively controlled, so even if Yale abandoned the Space-time Judgment Sword the formation would break in a second; at most he could use that method to make a random teleportation in an extreme situation.
"Well, it will be useful in the future once I obtain the Space Bloodline and increase my power."
Yale knew that although the skill wasn't extremely useful for him at the current moment due to the limitation, it would become a fearsome skill in the future.
After thinking in fearsome skills, Yale reminded his Time Slash; previously he had problems using it freely due to his lack of control of the Time Law. However, the situation reversed at that moment because not only Yale had awakened the Time Bloodline, he also had enough Origin Points to use that skill even without relying on the Time Law.
Those ten thousand Origin points seemed an incredible quantity back then, but the current Yale had more than thirty thousand, so even though it would exhaust a lot of his power, he could use it without problems.
Yale expected that to use Time Slash at any moment without relying on luck to avoid the backlash; he would still need about eight thousand Origin Points with his current understanding of the Time Law and the help of the Time Bloodline.
Of course, he could use fewer Origin points or didn't use them at all, but then there would be more possibilities of him suffering a backlash; eight thousand was the number to be safe using it without possibilities of backlash.
After his skills, Yale checked the Quest Menu and confirmed that the first sub-quest followed the pattern of the previous ones.
"Master the use of Spiritual Sense (Rank 3). Reward: ?????"
The reward was hidden, but usually, the hidden rewards proved to be the best ones. Moreover, Yale knew that fulfilling that sub-quest would be rather quick as he had already experimented the Spiritual Sense of the Practitioner Rank when he used Bloodline Force before.
Yale also had a new Skill Quest related to the Storage Space; he liked that, but he felt that he had lacked a diversity of Skill Quests since a long time ago.
"System special function improvement: Storage. Complete the fourth Main Chain Quest. Reward: The system will increase hundredfold the size of [Storage Space]. The number of living beings with a soul that could live inside the space will increase to ten."
The current space of the Storage Space was of hundred kilometers, but by the next quest description, Yale understood that there was a limit of how many people can be inside it.
"The current Storage Space limit for living beings with a soul is five. If the number is exceeded, the Storage Space will lose stability, and the people inside may be kicked out."
Yale was scared by that because Aiwai would die if she were kicked out of the Storage Space; Yale knew that he wouldn't be able to restore her soul to her current state after she went out.
Aiwai needed to be always inside, so only four more could enter there at the same time.
In case Yale needed to flee with random teleportation, he could use the Storage Space to be able to save more people, but the number was still extremely limited.
"Can I use the previous version of the Storage Space with time stopped to carry more people?"
In case of danger, Yale didn't want to let almost everyone die while fleeing with just a few people.
"Impossible. The Storage Space used a lot of energy to transform into its current state, going back is impossible. Even the previous version of the Storage Space would divide the time limit into every living being stored inside. It was impossible to carry a great number of people even if there was enough space."
The previous version would have let Yale carry far more people, even with the twenty-four-hour time limit divided, for just a random teleportation he could still carry a lot of people.
Sadly, he couldn't go back in case he needed it, but for Yale, meeting Aiwai again was far more important than being ready for saving a great number of people in case of danger. He would save them if he could do it as long they are acquainted with him, but he still had his priorities.
When Yale was already far enough from other people, he disappeared. Although it looked like Yale teleported, he had just entered into the Storage Space to see Aiwai again. He planned to go with Wyba later on, but he needed to speak with Aiwai in private before anything else.
