I didn't know if it was luck or misfortune.
The last time goods refreshed, perhaps it was his prayers that worked, a Return City Scroll appeared, along with countless goods that made him envious.
It could be said that at least half of the twenty product slots were top-grade.
Unbelievable...
Tang Yu had an urge to buy, buy, buy, unable to stop himself.
In the end, he restrained himself with great willpower, mainly because... even if he spent all his Source Crystals, he couldn't buy everything he wanted. But among them, he gritted his teeth and bought two items.
Basic Knowledge of Source Power price, 500 Source Crystals.
Note, it discusses basic knowledge of Source Power and its applications.
Remaining quantity, one.
High Probability Summoning Scroll price, 2500 Source Crystals.
Note, use in a tavern to increase the probability of summoning a high-potential adventurer (Note: there is still a possibility of summoning a D-level potential adventurer)
Remaining quantity, one.
Basic Knowledge of Source Power was a book that, from its appearance, looked no different from a regular compulsory education textbook.
This book, very cheap, a mere 500 Source Crystals.
The introduction stated it was a book about Source Power, and in Tang Yu's view, its importance surpassed even those items priced at thousands or tens of thousands of Source Crystals.
The appearance of the Abyssal Rift brought about the apocalypse, yet the earth-shattering changes worldwide were closely related to another thing.
Source Qi!
Tang Yu had heard a theory that, supposedly, before the apocalypse, Source Qi had already begun to emerge, and it had been discovered by scientists who called it a groundbreaking discovery. However, for various reasons, the discovery of Source Qi was not disclosed to the general public, and only after the apocalypse did people gradually become aware.
There was another theory that Source Qi was brought by the Abyssal Rift, more precisely, it was the connection of the Abyssal Rift to the Otherworld that allowed Source Qi to spread to Earth.
Tang Yu didn't know which theory was correct or if they were both wrong. But undoubtedly, Source Power possessed the nature of energy, but it was more than just that; its nature could change and extend infinitely.
Whether it was human Awakening, the Source Crystal Mine, mutant plants, and other changes appearing after the apocalypse, they were all inseparable from Source Qi.
However, unfortunately, this was a power entirely different from the previous scientific systems.
The value of Source Power was self-evident, yet people's understanding of it was minimal. It was a treasure lacking the key to access it, and even the treasure itself remained unknown.
Scientists once doubted the existence of Source Qi.
This thing couldn't be detected by instruments, nor could it be effectively proven. Even Awakeners couldn't perceive Source Power, only ability users could feel a kind of free-floating element in the air, coinciding with the special energy within their bodies.
This proved the existence of Source Qi and Source Power.
Hence, the status of ability users was elevated.
Similarly, Source Crystals contained abundant Source Energy, and thus Source Crystals became the most valued hard currency...
Even though Tang Yu was just a mere survivor, he knew about Source Power, but that was the extent of it.
Researching and utilizing Source Power? Impossible!
Small and medium-sized Sanctuaries didn't have the conditions for that, and even ability users were just at the instinctual stage of using their Source Energy.
Tang Yu once asked Eileen and Luo Zhe, and although they had a little understanding of Source Power, it wasn't much.
Take Eileen, for example, who comprehended the Ice Crystal and Ice Storm spells from a damaged spellbook. These belonged to the development and application of Source Energy. Even though it was a preliminary application, it was much better than relying on instinct.
Instinctively using Source Energy might create a huge spectacle, yet in reality, due to a lack of refinement, the power wasn't strong, and consumption was tremendous. If Eileen unleashed her entire ice power, freezing her surroundings with layers of frost, it might only last for a few seconds.
That spellbook involved the development and application of Source Energy.
Tang Yu had also looked at it but found it incomprehensible, like reading a celestial script, even though Eileen read it with great interest daily. Why couldn't he do it!
Advanced Mathematics wasn't this brutal!
Luo Zhe was the same; although his knowledge surpassed Eileen's, Luo Zhe wasn't a Mage, and the Warrior profession was equivalent to an ordinary Awakener. Tang Yu had learned Combat Skills from Luo Zhe, though he hadn't mastered them. What Luo Zhe knew didn't even require using Source Power, relying only on Qi Blood Power to trigger them.
Luo Zhe's understanding of Source Power was equally limited.
Holding the book of Basic Knowledge of Source Power, Tang Yu slowly opened it.
Suddenly, he paused.
Each page of the book contained few words and some illustrations, yet he widened his eyes and discovered those words were crooked, and the illustrations had a weird style, clearly something he couldn't comprehend.
Could this be like the spellbook, where he couldn't understand it at all?
It was supposed to be the most basic!
Tang Yu concentrated his mind on these words, and suddenly, an understanding formed in his heart.
"Source, the origin of all things, the root, the most essential power..."
As long as he focused on each word, corresponding information surfaced involuntarily in his mind. This was not about the text but directly transformed into a comprehensible meaning for him.
Tang Yu focused entirely, completely immersed in the vast ocean of the book.
Learning made me happy!
......
"You are the first batch of warriors in the Patrol Team, and the essential words have already been spoken by Director Tang. I have only two things to say, obey orders and... become stronger!"
In the valley behind the mountain, a cleared area had now become the training ground for the Patrol Team.
Luo Zhe was as stern-faced as ever, looking at these young recruits before him.
There were nine members in the first group to join the Patrol Team, including four Awakeners and five ordinary people with combat skills.
This number already exceeded Tang Yu's expectations. Among the Awakeners, apart from Peng Bo and Lu Xiaopeng, the other two were survivors previously rescued by Luo Zhe, who were lucky to awaken successfully after using the Awakening Headband.
By international convention, they were automatically enrolled in the Patrol Team, yet they showed no reluctance. Otherwise, they wouldn't have insisted on standing guard at the gate before.
The nine people listened to Luo Zhe's words, showing looks of surprise.
It wasn't because of the training. Patrol Teams in other Sanctuaries only maintained the Sanctuary's law and order and helped when Demonized Beasts attacked. Training was impossible, as even Awakeners might not have enough to eat regularly with the food supplies. Who would be responsible for the increased food consumption with training?
However, it was different here. Members of the Patrol Team knew that this was not an ordinary Sanctuary. Yet, what surprised them... was that Iron-faced Luo said so much at once. This was unprecedented since they had entered the Sanctuary.
They felt flattered all of a sudden.
"The essence of training is to fully exert everyone's combat strength. Looking at your slack postures, forget guarding the Sanctuary; even in a one-on-one situation, who among you can defeat a Demonized Beast?"
Peng Bo weakly raised his hand.
"Two? Three? Or a Second-tier Demonized Beast?"
Peng Bo weakly lowered his hand again.
"But with training, those mindless Demonized Beasts can be fought three against one by a general Awakener, and even ordinary people can cut off a Demonized Beast's head in the midst of battle."
Members of the Patrol Team breathed heavily.
They joined the Patrol Team for various reasons, some to repay kindness, others for benefits, but undoubtedly, after witnessing Director Tang crushing the Demon Tide with a wave of his hand, they were full of expectations for the Sanctuary's development. Similarly, choosing to join the Patrol Team meant being in constant presence of life and death; they were inherently not satisfied with the status quo.
Even those few ordinary people who couldn't awaken weren't content to live like ordinary survivors, waiting to die while getting by on meager meals.
Lu Xiaopeng felt the deepest connection. Even as a naturally awakened one, he wasn't a match for an ordinary Demonized Beast. But if training allowed him to fight three against one, wouldn't that fulfill his dream of punching Demonized Wolves and kicking Demonized Tigers?
Absolutely wonderful!
