Wizard of science

Li He looked at the human-shaped target in the field, his eyes focused, and the next moment he waved his hand, and a ball of orange flame appeared in the palm of his hand.

This is not the fire power similar to Mayfair's that he obtained by taking forbidden blood or fused blood potion, but the flame generated by using the fire energy factor stored in the body as a first-level wizard apprentice. This is an extraordinary power that belongs entirely to him.

Flicking your fingers, the flames began to dance, jumping from the palm to the thumb, then to the index finger, middle finger, ring finger, little finger, and finally jumping back to the palm of the hand, as nimbly as a fire elf dancing.

Squinting at the flames in his palm, Li He flicked it hard, and the flames shot out quickly, accurately hitting a wooden human-shaped target in the distance.

"call!"

After the flame hit, the volume skyrocketed, enveloping the entire wooden humanoid target and burning violently. Not long after, the entire wooden human-shaped target was burned to a crisp and was crumbling.

Li He looked at it and frowned slightly.

Although the wooden humanoid target was crumbling, it did not fall. The attack power of the flame is a bit weak.

Maybe it's because he only casts the lowest level spells. When he is promoted to a second-level or third-level wizard apprentice, or even a wizard, he can master and cast more powerful spells, and he can easily destroy wooden humanoid targets.

But to be honest, the power of the spell cast is indeed a bit low. It is more convenient and faster to use such a powerful spell to attack the enemy than to use the magic modified spell rifle ambition.

Therefore, spells need to be improved, and they need to be improved and cast using scientific methods, so that they can show sufficient effects. This is exactly the project he has been researching during this period - to find out the most effective way of spells by exploring the mechanism of spell production and the similarities and differences of spells. Excellent release method.

Li He glanced at the wooden human-shaped target that was still standing tenaciously, waved his hand again, and another ball of orange flame appeared in the palm of his hand.

He flicked his hand, and the flames flew quickly towards the wooden human-shaped target... a metal human-shaped target.

The flames hit, exploded, and enveloped the human-shaped target, but they only burned on the surface and eroded little by little to the inside, unable to harm the innermost parts.

Li He looked at it and grabbed his hand in the air.

The surrounding air surged, gathered, and compressed, forming an oxygen-rich air mass under Li He's intentional control.

Li He grabbed the air ball and swung it. The air ball hit the metal humanoid target and exploded quickly. The compressed oxygen quickly merges into the flame, and the flame instantly rises several meters. The color changes from orange to light blue, and the temperature rises sharply.

Oxygen has a combustion-supporting effect. Under this effect, the weak flame is greatly strengthened. The metal human-shaped target quickly softens and deforms during the burning. The continuous stream of iron flows down and falls to the ground to solidify into embarrassing gray spots.

Not bad... Li Hyuk commented in his heart after reading it... but it's not enough.

Squinting his eyes, Li He grabbed his hand again, and the moisture in the air was forcibly drawn, forming a water ball in the palm of his hand.

Turning it over with the other hand, he took out several small gray ores, which were calcium carbide (CaC2) with catalyst powder on the surface.

As soon as you put your hands together, the calcium carbide with the catalyst enters the water ball, reacts quickly inside, and generates a large number of bubbles.

That is the gas acetylene (C2H2) generated in the process of CaC2+2H2O→Ca(OH)2+C2H2↑.

Li He flicked his hand, and the water balloon filled with bubbles and growing in size flew towards the melted metal human-shaped target.

As soon as it got close, the water in the water balloon evaporated into water vapor, and the flammable acetylene gas contained inside was released, mixed with oxygen, and quickly reached the lower explosion limit of 2.5%.

The next moment it came into contact with the flame, it suddenly lit up.

"Boom!"

A huge explosion sounded, and a small sun seemed to be born in the spell testing site. The terrifying light and heat were released in a very short time, and then the shock wave roared across everything.

Dust rises.

Afterwards, the dust slowly dissipated.

Looking at it, the metal human-shaped target that was the target in the field was directly smashed. The wooden human-shaped target next to it was shattered into pieces by Chi Yu. A gray-black reinforced metal human-shaped target further away was also affected, with some distortion and deformation. It is conceivable that if it is an ordinary person, it can be directly shocked to death.

This power is pretty good... Li He nodded with satisfaction.

A simple flame attack is weak, but with the combustion of oxygen and the explosion of acetylene gas, the power cannot be underestimated.

In fact, he has considered that similar effects can be achieved by collecting hydrogen directly from the air to replace acetylene. However, in comparison, the hydrogen content in the atmosphere is only about 0.00005%, which is one part in two million, which is much smaller than 21% of oxygen and 0.25% of water vapor. It is not even an order of magnitude lower. It consumes a lot of money to absorb hydrogen. It is not as good as It is easy to draw water and use calcium carbide to react to generate acetylene gas.

Moreover, the explosion limit of acetylene gas is 2.5%-80%, and the explosion limit of hydrogen is 4.0%-75.6%. In other words, as long as the volume concentration of acetylene gas in the air exceeds 2.5%, it will explode in case of fire, while hydrogen gas must reach Only 4% will do.

Overall, acetylene gas wins.

Of course, using acetylene gas to cast spells requires the use of calcium carbide as a casting material, which increases the complexity, but it can be prepared in advance and carried with you. Moreover, with the portable space of Blackstone Castle, you can prepare the calcium carbide and put it in the castle, and use it in the outside world without worrying about running out.

Li He thought of this, stretched out his hand to grab it in front of him, and then flicked it away.

A large ball of flame flew out, containing a water ball inside. Inside the water ball were oxygen bubbles and several carbide stones that were reacting to produce acetylene gas.

The flames flew dozens of meters and hit the remaining gray-black reinforced metal human-shaped target.

The flames expand and then explode!

Another bright "little sun" was born in the field. Along with the rising flames, the roaring sound and the shock wave kicked up large amounts of dust.

As the dust fell, the only reinforced metal human-shaped target left in the field disappeared, turning into metal fragments on the ground and a large pool of molten iron.

It is indeed possible... After seeing the situation, Li He thought in his mind... let's call this improved spell "acetylene oxygen explosion fireball".

The success of the acetylene-oxygen fireball explosion showed that his efforts during this period were not in vain, and more importantly, he found a clear path - the wizard's spells are indeed mysterious, but they can still be improved using scientific methods. If it cannot be improved, it means that the analysis of spells is not enough, and the appropriate scientific method has not yet been found.

Li He narrowed his eyes slightly, thoughts were racing in his mind, and his thinking was divergent: He has now explored a clear path, and if he follows this path, the prospects are very broad. Biochemical transformation wizards, mechanical staffs, intelligent metal familiars, and steam wizard towers are all possible.

It seemed pretty good, and he had to hurry up and implement the remaining ideas.

Taking a deep breath, calming down, and calling Alex to clean up the spell testing site, Li He walked away, walked back to the No. 1 laboratory of the main castle, and entered a room next to the main research room.

Here is the result of another project he has been researching recently. In a sense, it is also the most important one because it is related to the Blood Countess.
