(I hope this chapter will not cause trouble to everyone. This prop will be used in the future, so let me introduce it in advance)

William never interrupted his research on spells and magic props. William applied to the old man for research, and the old man arranged a laboratory for him under the Rhine, which looked like William's Slytherin Lounge in Hogwarts.

"Thunderbolt explosion" can cause objects to explode, but just like William used in the battle with bill, this kind of explosion cannot break through the magician's guardian spell, and it has no effect except for causing smoke and noise. William wanted to develop a magic prop that could break through the wizard's guardian spell. William had some ideas. He called this imagined prop "bigbang". It is a kind of "**", but William did not want to use it to do terrorist attacks, but just used it to break through the wizard's guardian spell.

William made some ideas about the magic ball: If you want to break the protection of the guardian spell, one way is to have a strong shock wave that explodes instantly, which can break through the protection of magic. Second, the magic ball can corrode the magic power on the spell, just like burning a hole in a piece of paper. Obviously, the second point is difficult to achieve. There are many potions in potions that can weaken magic power, but it is particularly difficult to make it explode, because the configuration of the potion is a very sophisticated discipline, which is a variety of conditions such as acid and alkali environments.

They all have strict requirements, and adding other substances and potions will lose their effect. Even if this can be done, the corrosion rate must exceed the speed of the curse recovery. William learned from advanced magic theory that the magic distribution of the guardian spell is very dense, and maintaining the guardian spell requires continuous output of magic power. The density of the guardian spells of different wizards is different. Therefore, William can only give up solving this problem from the perspective of potion. What William is considering now is the first point - a violent explosion!

William wrote down the main issues that need to be overcome in his research in his notebook:

1. How to generate an explosion (howwww.piaotian.comge)

3. How to control the timing of explosion (when)

As well as some detailed questions, these questions were filled with two sheets of paper.

The first thing is how to generate an explosion. The potion can produce an explosion, but the strength is not enough. William thought of using substances with powerful magic power, such as the heart of a dragon, the blood of a dragon, the feathers of a phoenix, the tears of a phoenix, etc. as the medium, and then use the magic fluctuations to generate a resonance-like effect. The magic resonance releases energy if it is large enough, an explosion will occur.

Secondly, reduce the explosion range, and you can't be affected by yourself, right? William thinks there is no better method, so he can only use a smaller size but magically dense spherical prop to keep the explosion radius within one meter.

The other is how to control the timing of the explosion. William remembered the scene where his wand was chosen before school. Everyone's magic power was unique, and this uniqueness was similar to a fingerprint. William believed that the explosion could be controlled like a spell, or detonated. He also funnyly chose "Life is a big explosion, explosion!" As a spell, the final "explosion" is actually the most critical. Because when William shouted the last word, it would cause violent fluctuations of magic power, which would drive the "resonance" in the magic ball and then explode.

William asked the old man to make a lot of materials, including a pack of dragon's heart, five bottles of dragon blood, a small bottle of phoenix tears, and a pack of phoenix feathers. He also customized the crystal balls used to make prophecy balls. The difference is that the crystal ball is only half the size of a fist. Then William conducted an experiment. It has been the last month of Nibrongen, and William is very busy every day. However, he still squeezed out a lot of time to conduct the experiment.

Since Irving got engaged, he has been with Britney every day. Every day, he is long and short. William is also tactful. They are in love, and William doesn't want to be a light bulb.

William first tried to inject magic into the medium, but this was very difficult. William found that only the substances of the same creatures could store magic power, that is, the phoenix feathers mixed with phoenix tears and the dragon heart mixed with dragon blood could store magic power. The phoenix feathers are golden red. When William inputs magic power into the feathers, the feathers will emit golden light, and if William inputs too much magic power, the feathers will burn. After dropping the phoenix tears, the feathers can carry more magic power.

William put the phoenix feathers with phoenix tears into the open crystal ball, and then controlled Longkinus to introduce magic power into the phoenix feathers bit by bit, while dripping purple Spanish zara resin into the bottle. Magic is also an energy. This resin can avoid the dissipation of magic power in normal times, but it will not affect the resonance of magic. A trace of golden silk is constantly wrapped around the phoenix feathers floating in the crystal bottle, and the feathers begin to emit a golden light, from light gold to the bright gold that illuminates the entire laboratory. William observed that it has reached the critical point. Filled with the resin, pressed the crystal ball, and "restored as before" there is no trace of opening at the opening of the crystal ball. Now this half-palm magic ball is a "bomb" made by William. It is purple and has a flowing gold inside, as deep as the Milky Way in the night. William is very satisfied with his work.

How powerful is it? William stood one meter away from it, unfolding the magical defense of the guardian spell.

"Life is a big explosion, explosion!" As soon as the words fell, the purple golden ball floating in the air shone violently with golden light, trembling violently, and the golden light emerged bit by bit like the sunlight penetrated the dark clouds.

With a sound of "bang!", William's guardian spell was broken, and William flew backwards like a kite. The test bench on the other side was blown and cracked and collapsed from the middle.

With difficulty getting up, William's head buzzed and he blinked his confused eyes. William saw a messy laboratory and laughed heartlessly.
