International students at Hogwarts

Chapter 81 Look at this spell, it's long and thin

While bombing, Lu Ren was also driving his sand table slowly closer to Marcus.He needed a chance for Marcus to fly within range of his sun rune.

There are only two ways for him to win, either to shoot Marcus down with an explosive spell, or to close the distance and give him a deadly shot.

It's a pity that although the floating spell can change the direction of objects, it doesn't move as fast as a broom.If Marcus wanted to, he could pull the distance between the two to [-] meters in a few seconds.

But he can't do that.Because the distance is widened, Lu Ren will also be outside his attack range, and it will be miserable if he is judged to be a draw by Professor Snape - if it is another professor, Marcus feels that he will definitely be beaten. He was sentenced to lose, because he had already flown out of the duel ring in a strict sense.In other words, the referee was Snape, which made him feel a little more at ease.

At this time, Snape was silently calculating the position of Marcus, and he had already decided that once Marcus flew far away from the ring, he would judge him to lose!
Can Slytherin do whatever he wants?dream!Even Dumbledore can't save you!I said it, Snape!
Finally, Lu Ren thought of an idea when his mana was consumed by half.

Generally speaking, when Lu Ren casts the Explosive Curse, he wraps the magic power in a ball and shoots it out, and it will explode when it hits an object.

What does this look like?The relationship between anti-aircraft guns and aircraft.

The efficiency of a single anti-aircraft gun to hit an aircraft is extremely low. Dozens or hundreds of anti-aircraft guns fire continuously when the anti-aircraft gun is fired, creating an explosive "minefield" and "barrage" where the aircraft must pass. As long as the plane comes over, let it escape from death.

Therefore, it is said that the aircraft relies on the net firepower rather than the burst fire.

So here comes the question, how can Lu Ren use net firepower alone?The effect of him shooting a machine gun alone is already shocking.

What's more terrible is that the fuze of Lu Ren's "cannonball" is "impact fuze", and the magic spell will explode when it hits the enemy. The more effective means of air defense are "delay fuze" and "VT fuze", that is, "Time-changing fuze".The former explodes according to the prescribed time, while the latter intelligently and automatically adjusts the detonation time according to the distance of the explosive.

Lu Ren only had the most primitive means.

Does he have the ability to develop the latter two methods on the spot?Sorry, Lu Ren can't do it.

Now he has to control the sand table to carry himself to fly, and also suppress Marcus with firepower - otherwise, with Marcus' flying speed, Lu Ren will be hit as a target.

It's not easy for him to do this.

What's more, according to the statistics of the U.S. Navy after the war, shooting down an aircraft requires more than 2800 ordinary shells.What's more worth mentioning is that the shells with the VT fuse just mentioned need more than [-] rounds to shoot down an aircraft.

2800 explosive spells?Lu Ren has already been squeezed dry!Even 300 rounds are very difficult!

So making spells look like cannonballs has no future.

Lu Ren noticed this.

So why does it have to be dotted?
Obviously it's just a lump of magic power, wrap it up and throw it out...

So why can't the magic be stretched a bit longer?

What I used was not a traditional wizard's spell—although that's what I said.The words yelled are just the ability to give magical power to explode.

Lu Ren thought for a while, swung his wand down, and stretched the magic power as far as possible before casting the spell, and then the audience saw that Lu Ren forced out a wave of light.

"Confringo-Change!"

Marcus people are stupid.

You tell me it's called the Explosive Curse? !

Isn't this really something like Eastern sword energy?

Why are you so long!
The consumption of this spell is several times that of the previous "cannonball", but it is a hundred times longer!
Marcus visually estimated that the "sword energy" just now must be 5 feet long—that is, 1.5 meters!
Although it looked weak and dissipated within a few tens of meters, Marcus didn't dare to bet on its power.

If it is really fierce, a person may be cut in half after eating a spell.No matter how superb the medical skills of Hogwarts' school doctors are, they can't save a person who was cut in half, right?Especially the ones cut vertically...

The students in the audience were in an uproar, and the professors also showed surprise.In their cognition, the Explosive Curse is a ray of light that explodes wherever it hits.It's surprising that Lu Ren fired explosive spells like a machine gun, but it's still understandable, but what the hell is this "sword energy"?

It's like a gun, it fires fast and has a lot of bullets, which is understandable, but isn't it a bit too much for you to shoot a space rift with one shot?
Seeing that the experiment was successful, Lu Ren smiled like a child.

He had long since discovered the regularity of Marcus's evasive ways.If Lu Ren fired two explosive spells in succession, in order to avoid them, Marcus would habitually fly between the two spells. If it was a point attack, it would be harmless.But this linear spell will completely block the evasion space on his left and right.

The only places he can fly are up and down and front and back.

"Then what if I cast an Explosive spell on the top and bottom? These two spells can each have a little angle, so that they can also block Marcus's rear, and he can only move forward!"

Lu Ren did whatever he thought of, and he didn't want Marcus to be familiar with his attacking methods.

The four curses were shot out almost in no particular order.

Marcus yelled, "Damn!"

He subconsciously flew into the middle of the spell, and then he keenly judged that all directions of him were locked.Without hesitation, he immediately drove his broom forward.

Lu Ren was overjoyed: "I got it!"

In front of Marcus, there is another explosive curse waiting for him!
Marcus was so decisive that he jumped off the broom!Before jumping off, he pushed the broom into the sky, just in time to avoid the oncoming explosion curse.

Marcus plummeted to the ground.There was a burst of exclamation from the stands of Slytherin College, while Gryffindor's place became a sea of ​​joy when Lu Ren suppressed Marcus.

It doesn't matter if you can win or not, it's already amazing to be able to beat the first grade and the fifth grade like this!Would you expect a La Liga team to beat a La Liga team?

Marcus didn't panic at all, his hand holding the wand shook in the air, "The broom is coming!" He cast a coming spell, the broom that was flying into the sky turned its head, and rushed towards Marcus again over!
A classic pursuit problem was born.

Assuming that the initial velocity of the broom is 20m/s, Marcus jumps off the broom to do free fall when he is 50 meters above the ground.The broom flew upwards at an angle of 30°, and he released the Flying Curse 1 second after falling.Ignoring the time of the broom turning around, the initial velocity of the broom is zero after turning around.Gravitational acceleration is taken as 10m/.What is the minimum average speed of the broom before Marcus hits the ground?

　The book will be recommended at 2 o'clock this afternoon, I'm really nervous!

　　I hope I can do well in my water push test.

　　Today, Chapter 2 is advanced to 2 o'clock.The next chapter will end the arena plot, and a new one will start tomorrow.
