After Christmas, it's time for the final exams.

After the exam, there will be a holiday, and within a few days of the holiday, the Spring Festival will come. Although the preparation is about to take the exam, Lan Zeguang does not need to review at all, because he signed a contract with Maria, so Lu Yiyi does not need to prepare for the exam. Both of these are open, and they cheat!

Coach, I really want to implant the knowledge directly into my brain!

Every time the exam started, the scumbags began to cry and grab the ground. However, Xueshen and Xueba have already seen through it, of course, in addition to Xueba and Xueshen having confidence, there is another kind of person who is not depressed at all: that seems to be the legendary Xuescumren God who has no intention of passing and simply gives up the information.

I heard that universities are fighting all night, but even so, the week before the exam, everyone's revision efficiency is extremely low, and the two days before the exam rises exponentially, and the day before the exam, especially the night before the exam, the review efficiency is unprecedented and unprecedented.

Of course, this is a bit overflowing.

-- Because everyone is the same.

However, today, for the benefit of society and college students, GPA has launched a new service: you only need to pay the same soul as the test subject credits, and you can completely master that subject without pain, and ensure that you can pass the exam.

Why not a perfect score?

Because...... If you are very poor at math, if you don't do good calculations, such as digital signal processing, you won't be able to live, and if you don't have the ability to do math calculations, I'm afraid you can only get to a passing grade.

So. You can pay more souls to learn the knowledge of signals and systems and advanced mathematics in a package. One-stop service, painless learning. Give you the most perfect knowledge and make your future full of hope!

Of course, if you don't think it's practical to spend a lot of knowledge to learn, you can also choose to go directly to the subject. Don't have three years of souls, don't have two years of souls, don't want one year of souls, just three months. Just three months of soul will allow you to pass guò one credit!

When is this time when you don't sell your soul to earn credits and knowledge?

Log in to your GPA. Enter the knowledge you wish to acquire, and enter the subjects you want to pass through. The amount is preferred, and the top 50 have discounts, and the number of places is limited. Don't hurry up and grab it! Bring your friends and family. Come and enjoy the excellent service brought to you by Lord Lucifer!

You can try it out and pay later, and then pay your soul when you are satisfied with the results.

Miss it once, and you'll regret it for the rest of your life! Lord Lucifer is waiting for you!

……

Being able to come up with such an advertising slogan, Lan Zeguang found that his brain was not small at all.

Speaking of which, when has Lan Zeguang's brain hole been too small?

The reason for this is all in response to Lucifer's call to expand the speed of soul collection. At the end of the semester, all Lan Zeguang can think of is taking advantage of the time when everyone is going to take the exam. Take a good look at the soul. By the way, he also began to try to expand Lucifer's business.

You know, Lan Zeguang's website can develop. It's all because Mr. Gong drove the offline publicity. However, Mr. Gong's business scope is still narrow, after all, it is the underworld, and Mr. Gong's propaganda targets are mostly people who are frustrated in business, officialdom, and emotional fields. Therefore, most of the tasks are also more realistic.

But you must know that the almighty Lord Lucifer can not only solve real disputes, but also teach people knowledge, change fate, and so on!

With so many businesses, is it really good not to develop them?

Therefore, Lan Zeguang took advantage of the turmoil of the exam to publicize it.

Because there was a publicity for the make-up exam at the beginning of the school year, this advertisement hit the post bar and spread again. In just one night, there were more than 100 requests on the website, either they wanted to learn something directly, or they just wanted to directly take credits. Of course, there are also people who find the master and then make some other commissions.

More than 100 people came in one day, what should I do?

Even if Lucifer had the knowledge from college to graduate school in his head, he would definitely be tired of receiving so many people in one day.

Naturally, Lan Zeguang had an idea: he asked Lucifer to split the posture into science and engineering, literature and history, art, and economics and management, and taught them to Shana, Aier, Xue Wuxian and Yang Chengyu, and even Lu Yiyi. These relatively idle "servants" let them take these memories to perform tasks in different categories, and then they used the souls they earned using this knowledge to return to Lucifer, and enough tuition, and then divide one-fifth of each mission into their own use and offerings.

As for getting credits or something, it's up to them to figure it out on their own.

Of course, the souls collected by Lu Yiyi are for his own use, and of course, sometimes they will be given to Lan Zeguang, and if they are given to Lan Zeguang, then it will probably be Lucifer's.

All in all, it's called "credit". Of course, the real debit credit is not calculated in this way, but Lan Zeguang is too troublesome to think about it so much.

As a result, this is simply out of control, and more and more people have heard that they can sell their souls to learn knowledge, and even some teachers know about it. For this reason, it seems that it has also attracted the attention of the school authorities. Of course, this is not a troublesome matter, at a unified meeting at the school, Lan Zeguang asked Lucifer to come to a collective brainwashing hint, and then there is no need to worry about it anymore.

During the period of the exam, an average of 100 years of soul can be received every day, but relatively speaking, it is still a bit insufficient.

Do you really want to open a live to attract popularity?

However, in comparison, there are more things in front of him that need to be solved by Lan Zeguang.

First of all, there is the problem of location communicators. After a period of hardware manufacturing, plus the positioning and debugging of Dong Chen and Lan Zeguang. The basic functions of the position communicator have already been realized. The GSM network service of the copper drum operator, with this peanut shell-sized locator, can publish its location at all times, even if there is no GPS signal indoors, it can also obtain location information from the base station through guò.

Although that location is not accurate, the density of base stations in today's cities is very high, and even if Lucifer teleports to the vicinity of the base station, the enemy may be spotted.

However, this is limited to the locator communicating with the server, sending commands and numbers to each other. But there is one link that is difficult to solve:

Because Lucifer couldn't understand the GPS signals of the world, Lan Zeguang had to find an algorithm to convert those numbers into numbers that Lucifer and Maria could read. However, this algorithm is like a mystery, and like the method commonly used when debugging PID, it has to be debugged by the legendary "approaching method".

What is the "approaching method"?

The approximation method is to find a median value that meets the test requirements through countless tests, and then this value is stable and down, which is the final parameter required for the test model. In order to find this parameter, Lan Zeguang first bittered Lucifer, and then Maria.

You know, testing this parameter is a dirty job.

Spatial teleportation is very useful, but what if the location where the teleportation falls is very tricky?

Because of Lan Zeguang, the "location information" that they can understand is always very strange because of the Lucifer they use GPS location signal conversion, so that Lucifer, who can't see the transmission location, has been transmitted to an unpleasant place at the beginning. For example, Lan Zeguang stood in the playground, and Lucifer teleported to the sewer under the playground: it was still embedded in the wall.

The second time, Lucifer was stuck in the mud of the flower garden.

The third time, Lucifer almost teleported a passerby into two parts.

So, Lan Zeguang hurriedly put this dangerous experiment on the outskirts, and then the angry Lucifer handed over the identity of the guinea pig of this experiment to Maria, and then ...... One qiē is harmonious.

Anyway, Maria is a shake M, anyway, in the suburbs, the kind of ground that won't hurt people, shine, and you can teleport how you like!

As a result, many of the tragic trials ended after a week. Because of the inaccuracy of GPS positioning and base station positioning, the final debugging result is to let Lucifer and Maria transmit the location information to the location at a horizontal altitude of 100 meters. If it is not in the downtown area with dense high-rise buildings, there is generally no problem. What's more, they can also feel the consumption of their souls when teleporting, to determine whether the landing point of the teleportation has touched an object.

Then, Lan Zeguang handed over the debugged bracelet to Mr. Gong to find a factory for mass production.

At this time, New Year's Day has also passed, and the school's exams are over, and it is time to prepare for the holiday. During this period, there were no more demons who came to Lan Zeguang for trouble, and it was so quiet that Lan Zeguang felt incredible.

But when it comes to holidays, Lan Zeguang is a little hesitant.

Because Lan Zeguang should be a boy in the eyes of his parents and relatives, but Lan Zeguang at this time is a girl. On the phone, Lan Zeguang can use his voice to deceive his family, but what about reality?

Lan Zeguang has already thought about it: he plans to wear men's clothes directly at home. As for Lucifer or something, it's not a problem to find him a place to rent a house near his home.

As for Lu Yiyi...... Although there is a conflict with the family, in the Spring Festival, the contradiction can be resolved. In fact, there are still a few days before the arrival of spring, and Lan Zeguang has made an excuse to drag these few days over. On Chinese New Year's Eve, he took Lucifer and Luyi back home in a bullet train. As for Mary, the unregistered person is lying on the roof of the car!

25kv traction AC is very cool.

Anyway, in desperation, Lan Zeguang still changed into men's clothes, returned home, opened the door, and said loudly to his family:

"Happy New Year!" (To be continued......)
