Chapter 650: The Sand of Time and the New Lesson Schedule
The wooden box is the size of a palm, purple-red, with straight wood texture and delicate feel. It has bare sides without any decoration or magic patterns, like an ordinary jewelry box.
Zheng Qing originally thought that what he saw after opening the box would be a pocket watch.
But what appeared in his sight was an hourglass.
The hourglass lie quietly on the red velvet cloth, with ochre wooden bases at both ends. The bases are connected by three slender black columns. The columns are engraved with dense spells, as thin as mosquito feet. Two water-drop-like transparent glass balls are sandwiched in the center of the three thin columns. One glass cover is empty, and the other is filled with evenly particles of translucent sand.
"It's filled with sand of time."
The professor's voice rang in the ears of the young wizard: "Sand of Time is actually the fossil of the worm eggs of the worm. You have seen the fossils of the worm eggs in the blank space, right... It's perfect to use their fossils to carry the power of time... The number of these worm sands has been carefully calculated by the relevant departments. There are not many pellets, but not many pellets... Do you see the spells engraved on the edges of the upper and lower bases? Every time you turn the hourglass upside down and recite the spells on the pellet side of the blank, you can flow back three and a half hours of standard time."
Zheng Qing resisted the urge to turn the hourglass in his hand.
At this moment, from the corner of his eyes, he saw Jiang Yu holding an identical time converter in his hand, and a curiosity suddenly arose in his heart: "Professor, what will happen if we two turn this hourglass at the same time?"
"Theoretically, there will be two 'time knots'."
Lao Yao bit his pipe again and calmly vomited two tangled smoke rings: "Because of the mutual independence of the timeline, you and her will enter different time knots and finally return to the same time line... But as I often emphasize in class, magic is a very exquisite skill, and any subtle changes may cause completely different consequences. You should have seen it many times in the spell class in the first year. Two people cast a bonding spell at the same time, and the probability of flying vines entangling into dead knots is very high."
Zheng Qing understood, and this was Lao Yao's tactful reminder that it was best not to do that.
"Professor, do we need to practice now?" The witch's pleasant voice rang out again. She raised the hourglass in her hand and asked cautiously: "If I only miss one-seventh of the sand of time when I turn the hourglass and then turn it back, does it mean that time will only flow back half an hour?"
Furu—
Lao Yao took a heavy breath of the pipe, spit out a large ball of thick smoke, and his eyebrows were twisted.
"Absolutely don't do this."
He had a serious expression and a stern tone: "You lack the subtle control ability of high-level wizards, and you cannot accurately measure how much time sand you have leaked... and the hourglass has the same time conversion ability on the left and right sides... This means that you are easily trapped in the time corridor. In short, you are easily confused in the process of repeatedly turning time inverting time. I don't expect you to have a deep understanding of using this high-level alchemy, but only ask you to be safe and secure and not cause any accidents..."
As he said that, he pulled out two rolls of parchment from the drawer, pulled off the ribbon, and spread it in front of the two young wizards.
"...This is the application materials you just signed in the afternoon, so you still have the impression."
The professor's eyebrows were twisted and the parchment was shaking, whirring: "Users need to remain invisible throughout the time travel; they can only be within the reporting scope and follow the reporting route; any activity that is out of the reporting scope will be cancelled once it is discovered and transferred to the Danhage Criminal Court. The verdict period is generally more than ten years... These terms have been explained to you at that time, and the time conversion is less than three and a half hours, and it is also within the "out of the reporting scope"... Are there any questions?"
The two frightened young men shook their heads in one go, holding the hourglass in their hands tremblingly, fearing that the sand on one side would accidentally leak to the other side.
This look is a bit overkill.
"It doesn't matter if you don't recite the spell."
Lao Yao noticed their cautious appearance, and a trace of helplessness appeared in his eyes. He took the funnel in Zheng Qing's hand and flipped it around like a signal: "Did you see? If you don't chant the spell, Shi Zhisha will not leak down... This matter... If you don't talk about it, you don't take it seriously; if you whisper a little, you will be scared like quails again!"
Speaking of this, he stopped, sprayed two balls of smoke with sparks from his nostrils, and then spoke again: "As for the exercises that classmate Jiang Yu just mentioned, I personally don't need them. As I said before, these two time converters are fool-like operations, and you can get started directly at your level... Of course, for safety reasons, I will take care of you when you use them for the first time tomorrow... The first section of tomorrow is my spell class, don't bring the wrong textbook!"
Zheng Qing immediately carefully put the hourglass back into the wooden box and then unfolded his new lesson schedule.
After a brief browsing, he found that compared with when he submitted, Lao Yao had revised five courses in total - Thursday afternoon was a new course called "Clan Deformation". Considering his mastery of the transformation, Zheng Qing felt that this course should not be difficult; on Friday morning, the "Spiritual Talisman and Treasure Talisman" was replaced with "Making and Maintenance of Talisman Soldiers". Lao Yao had mentioned it before, but Zheng Qing was not too surprised.
What surprised him was three classes on Saturday afternoon and evening. Lao Yao removed the courses in several major talismans selected by Zheng Qing and replaced them with the "Introduction to Dimensional School", "Principle of Convergence" and "Abusduo Conjecture".
Just look at the names of these courses and you will know what they are related to.
"Is the school still offering such classes?" Zheng Qing couldn't help but look up at the professor behind the desk, without hiding the surprise in his tone.
He originally thought that knowledge related to the forbidden spell would be strictly blocked by relevant departments.
"Not only students are choosing courses, but also students." The dean of Jiuyou College looked at the young public-funded students meaningfully: "Sometimes, it is not easy to choose a student who meets the requirements in one course, so you must cherish the last half year of studying and living in school..."
Then his eyes moved to the witch next to him, and the tone changed: "You have received the new lesson schedule. From Monday to Thursday, there are five classes every day, from 8:30 to 1:30 in the morning, and you need to have two classes for others; from 2:00 to 5:00 in the afternoon, and the same, there are two classes for others; from 6:00 to 9:00 in the evening, and others rest, you need to have another class, and you don't need to use hourglass in this class.
Because it is a practical class on Friday afternoon, in order to avoid injury affecting the time change, you only have one practical class on Friday afternoon and you can also take a break in the evening.
There are five classes a day on Saturday, the same as Monday to Thursday.
Jiang Yu has to attend two more classes on Sunday because you are six credits less than Zheng Qing.
In this way, you need to use a time converter eleven times a week, each time converting for three and a half hours, a total of thirty-eight hours and thirty minutes, meeting the requirements of the application materials... This is the basic situation, what else needs to be supplemented?"
He raised his eyelids and his eyes were surfing on the faces of the two young wizards. The two young wizards sighed together and shook their heads in an orderly manner.
It's already so bad, so what else needs to be added!
