Hogwarts Staff Maker

The transmission process of the Rainbow Bridge was comfortable and smooth, and the transmission distance was far enough, but Liu Sen did not dare to do more experiments. After all, he was still in the "past" timeline, and keeping a low profile was the top priority.

The colorful light effect that penetrated the sky and the earth when the Rainbow Bridge was turned on was quite impressive, but it was too low-key.

Liu Sen, with his imagination running wild, couldn't help but think of another Marvel teleportation move in his memory - the rune portal unique to the Kamar-Taj wizard, which is the circle portal!

Wherever you want to go, just stretch out your hand and draw it, and the sparking circle will directly connect two places!

Although it is not as cool as the Rainbow Bridge, it is efficient and practical, and the experience is the same as opening a door! It can even be used as a space cutting skill!

The research on space technology involves too much theoretical knowledge. The Rainbow Bridge is actually just a modification of the idea of ​​Apparition.

However, the research and development difficulty of drawing a circle to directly connect a space thousands of miles away is too high.

Even after using up the time for two time travels, Liu Sen still hadn't found a technical breakthrough.

However, after spending more than two years alone, Liu Sen feels that he has gained a lot.

In addition to the Rainbow Bridge technology, his knowledge and skills in all aspects have been well accumulated.

After returning to the long-lost castle, Liu Sen

Turning on the stealth function, he first returned the time-turner to the worried Hermione.

Then he walked to the office of Professor Snape, the royal alchemist.

After knocking on the door twice perfunctorily, Liu Sen slipped in.

Snape's unique low voice sounded from behind a pile of bottles and jars, "You should be glad that you are not a Slytherin student, otherwise I would punish you by making you copy the word 'knock' a thousand times!"

Liu Sen removed his invisibility, stepped forward with a playful smile, and said in a teasing but sincere tone: "Professor! Long time no see!"

Snape calmly finished the experiment in his hands, then raised his head and was about to make a sarcastic remark.

But when he saw Liu Sen's appearance, he was shocked and almost dropped the medicine bottle in his hand.

"What's wrong with you? Why did you suddenly grow taller?"

That’s right, in more than two years, Liu Sen, who is in the growth stage, has become more than a head taller than before!

Liu Sen had accidentally traveled a year when he captured Pettigrew, and his height had also increased dramatically. Facing the doubts of the little wizards, he finally found an excuse to evade them.

But this time they are too long and the distance between them is not far, so it is hard to make excuses!

"Professor, do you have any shrinking potion? The kind that makes you look smaller after drinking it!"

Snape squinted his eyes and stared for a while, then hugged his shoulders and said gloatingly, "Did you take the wrong potion? How did you grow up overnight?"

Liu Sen shrugged. He had nothing to hide from Snape.

"I am a hard-working person who decided to go back to two years ago to learn more knowledge! I had a happy and fulfilling study time!"

I thought the other party would look disgusted and then say a few bad words in a proud manner.

Unexpectedly, Snape became unusually serious and asked excitedly, "You used a time-turner! And you went back two years! How did you do that? This is impossible!"

"What's impossible? I'm back, right? I also went back once before when I captured Pettigrew, but it was only for a year."

Snape paced back and forth excitedly. "In history, the wizards who have successfully traveled back in time have only been able to go back a few months at most! Only a few wizards who have tried to go back further in time have survived!"

Liu Sen blinked his eyes. Is it that difficult?

But on second thought, the time converter does require a lot of magic. If ordinary wizards cannot provide stable magic output during the time travel, they may be trapped in the turbulence of time! Or die from magic exhaustion! Hermione did not feel any pressure going back to the past hour by hour.

But as the time of regression increases, the magic power consumed will increase exponentially.

The magic power consumed in a year is about 10 ha, but in more than 2 years, 50 ha has been consumed!

For a player like Liu Sen, whose magic power is almost infinite, the magic power of dozens of Harry Potters is just a number. But for others, it is a huge gap!

There is a solution. Normally, you can drink dozens of bottles of priceless but highly side-effect magic recovery potions during the time travel process.

The most ruthless ones can even sacrifice dozens of magicians and use their flesh and blood and magic power as fuel for time travel!

The next step is to invent a tool that can store the combined magic power of dozens or even hundreds of adult wizards...

After revealing the consumption of magic power to Snape, the other party's face instantly became extremely bad.

It took him a while to come to his senses, and he took out a bottle of medicine from the cabinet and handed it to Liu Sen.

"Take 2 drops at a time, the effect will last for a day, this bottle will last you until the holidays!"

"Thank you, professor!" Seeing that the other party was depressed, Liu Sen planned to find some topic.

"By the way, Professor, what are you researching?"

Snape snorted coldly and picked up the transparent liquid extracted from the shelf.

"This is made from the experimental materials you gave me earlier. By the way...if you want to return to your 'normal' appearance permanently, you can drink some of this!"

Liu Sen remembered that these were the "elixirs of life" he obtained by using the Philosopher's Stone to transform beer, drinks and mineral water!

"This medicine is amazing! After taking it, you can really turn back the aging process! But the side effects are equally terrible! After repeated experiments, I found two feasible solutions.

The first one is rejuvenation, but you will lose all your memory!"

Liu Sen has seen this before. Ron's owl, Errol, is like this!

"The second one is rejuvenation, retaining the memory, but... changing the gender!"

"Puff! What's changing?" Liu Sen was completely unsettled. His Holy Light was like this. He didn't expect that after he had finally developed some elixir of immortality, it could change gender at any time!

Snape gave a sinister smile, "Change gender! Do you want to try it?"

"You try first! Goodbye! No time to wave!"

After saying that, Liu Sen quickly fled the scene. It would be better not to have this dishonest elixir of life!

After a long-awaited reunion with his classmates and friends, Liu Sen opened Lupin's office again and shared with the CEO the ideas he had come up with when he was bored in the past two years.

"You mean... opening a film company? Making movies?" Lupin was a little confused. He thought that after such a long time, he had been able to keep up with the other party's eccentric thinking, but now he found that there was still a little gap.

He knew what the movies were. During their in-depth tour of the Muggle world, they had been to a cinema and watched several movies.

If it was about opening a cinema, he could understand it. After all, movies were quite interesting and there was definitely a market for them in the wizarding world. But why did they set up a film company to make their own movies? Lupin immediately asked the question in his mind.

Liu Sen said, "The cinema is going to open! But it needs to be renovated. The movies need to have 5D effects! It will make you feel like you are there! It will increase the sense of immersion!"

Lupin nodded and took out a small notebook to write it down.

“We need to open a film company too!”

"But... from what I know, the cost of filming a movie should be quite high, right? And the population of our wizarding world is far less than that of Muggles, so the return on investment may not be high!"

"Hey, hey, who said I want to show it to the wizards?"

Liu Sen blinked and raised the corners of his mouth.

"We can use magic instead of special effects! After we make the movie, we can show it in the Muggle world! Wouldn't the return rate be higher? Besides... movies can guide people's thinking!"
