Thursday of the third week is March 5th, which is also the 'Stinging Day'.

The so-called stinging refers to the meaning of the 'stinging insect' being frightened by the spring thunder and running away. The insects, which had been silent for a winter, crawled out of their burrows as the weather warmed up and the spring thunder burst out, awakening the vitality of the land.

Of course, this is only a 'theoretical' scenario. But just like the 'rational man' in economics, the situation in theory tends to deviate in one way or another when it comes to practice.

For example, in the winter of 08-09, due to the anomaly of the silent return of the previous year, the time for insects to lie dormant in the ground was greatly shortened, and many insects have gushed out of their burrows with the black tide of spring, so that when it comes to the real 'sting day', the protagonist of this solar term has become a supporting role.

But regardless of whether the bugs have crawled out of the underground caverns or not, the spring thunder that should have been heard on the day of the sting, the astrological superintendent of the First University will still reverberate the entire campus.

The climate on campus had been humid since Wednesday night, and the next morning, after Zheng Qing had finished his morning class, the sun had not yet risen, and the entire sky was shrouded in a thick layer of cumulonimbus clouds.

At noon, the rumbling thunder slowly sounded from far and near, and even through the glass window of the classroom, Zheng Qing could deeply feel the trembling in the air.

"On March 5th, it was stinging, around 10 o'clock in the afternoon, the spring thunder was gusting, the drizzle was continuous, and the spring was full of joy. ”

Zheng Qing grabbed the quill and left such a record in his weekly notebook.

Since Professor Yi taught a new divination technique to everyone in Tuesday's divination class, Zheng Qing suddenly discovered a new hobby of his own, which is to organize weekly notebooks.

Originally, he just drew the line chart with the mentality of coping with homework, but after the hasty drawing was completed, Zheng Qing supplemented the moving average and trend line in the way described in the textbook, and suddenly found that his fortune was clear under the pen.

On the whole, after entering the school, the fortune is on the rise.

For example, he met a lot of friends, defeated the multi-headed demon, learned Transfiguration, had a girlfriend, became a Merlin Medal winner, led the hunting team to win the freshman championship, won the title of the Great Arcana 'World', and had a certain degree of close relationship with Su Da Beauty - of course, whether the last one is a blessing or a curse, Zheng Qing is not sure for the time being, but this does not affect him to judge whether his luck is good or bad.

But as the saying goes, even if the fortune in the ascending channel will turn down from time to time, stepping on the moving average and trend line to consolidate the foundation - such as the occasional outburst of head disease, repeated hospitalization, being attacked by a demon or a vampire duke, and unsatisfactory final exam results, etc.

Originally, it didn't matter, it was nothing more than a reminiscence of the past experience.

However, as Zheng Qing completely completed the line chart, outlining the moving average and trend line, he immediately noticed that his fortune was in a state of rising and falling, in the terminology of fortune divination, his recent fortune line has been consolidating downward for many days, and the number of times the yin line appears is far more than the yang line.

Even if they are small black candlesticks that may seem insignificant, a trend is a trend after all. For example, the evil demon Satogua, who broke through the boundary two days ago, is an example of this trend. Although the powerful man of the school poked the monster's eyeballs to shreds, the experience of that day still left a heavy barefoot yin line on Zheng Qing's line chart.

Seeing that the line has broken the seven-day moving average, and is stepping on the thirteen-day moving average, Zheng Qing really can't make himself feel better - from a negative point of view, this mentality is constantly pulling down his score in the past few days, for example, after knowing that his recent bad luck yesterday, Zheng Qing was naturally in a bad mood, so the chart drawn yesterday this morning is a black line that is neither long nor short.

But from another point of view, this just shows the precision of fortune divination.

As the saying goes, 'divination is risky, divination needs to be cautious', any kind of attempt to see the future through the long river of time will be affected by the waves of the long river of time. The light ones have a decaying fortune, and the heavy ones have a lot of bad luck.

Although the trend divination method has avoided some of the risks of divination through clever means, there are still some remnants. For example, shamans who practice or use this method of divination will have a yin line on the day.

Zheng Qing doesn't like bad luck to happen every day.

So he drew the line chart on the first day, peeked at his own trend, and then put the chart on the shelf until next Tuesday.

Although the chart is put away, it is difficult to calm down the turbulent state of mind.

At Xiao Xiao's suggestion, Zheng Qing simply began to organize his weekly notebook, summarize the information that remained between the lines of the previous words, and summarize it by date, so that when it is necessary to draw, he can draw a more accurate and accurate line chart.

In addition, he also learned from Dr. Xiao Da and developed a good habit of taking notes casually - since he already knew that the big and small things that happened every day were important information during divination, Zheng Qing naturally would not waste them in vain.

Just like now, although Professor Li of Pharmacy on the podium was analyzing a new antidote prescription with everyone, Zheng Qing noticed the scene of spring thunder and spring rain outside the window, and immediately opened his notebook and recorded it.

“...... After the black tide, the five poisons breed!"

On the podium, Professor Li's breathless voice was a little weak, and Zheng Qing had to prick up his ears to hear clearly:

"Which five poisons?"

"Naturally, there are centipedes, scorpions, geckos, toads, and poisonous snakes, these five poisons. ”

"In the winter, they hide in underground burrows and sleep through the cold. In the coming year, when the spring thunder is blowing...... For example, now," Professor Li stretched out his hand and pointed out the window, and the heads of everyone in the hall seemed to be under control, and they followed the direction of the professor's finger and looked at it together.

It's like a robot.

Zheng Qing couldn't help but laugh a few times, which attracted the sideways glances of the surrounding classmates.

“...... When the spring thunder bursts, they will come out of the cave and wreak havoc for a period of time before the Dragon Boat Festival. ”

"Some people may say, didn't there already be a lot of insects crawling out of the burrows during the black tide in the school a few days ago?

"This is because the five poisons are naturally insects, but insects are not only the five poisons. These five poisons, affected by mysterious magic, can, and will only appear and reproduce after the sting and before the Dragon Boat Festival. ”

"Therefore, the antidote taught to you in these classes must be learned well, memorized, and used in life...... This is very good for your safety in school. ”
