Richard moved.

First, find a square glass container from the wooden shelf, put it on the annular experimental table, then lift the flour bag you got before, pour it into the container, and then = pour in an appropriate amount of water, so that the ratio of flour to water is about 2:1.

Stir it with a glass stick so that the flour and water are well mixed and turn into something like a batter.

Richard looked at the contents of the container, touched his chin, and the next moment released a spell, controlling the batter to break away from the container, fly into the air, change form, and turn into a circular shield.

Stretching out his hand, Richard tentatively touched it, obviously soft and could be easily penetrated.

Retracting his hand, Richard clenched his fists, speeding up and hitting harder.

"Bang!"

With a muffled sound, the batter quickly solidified, like a stone shield carved from a white boulder.

"Hmm-"

Richard withdrew his hand, rubbed his aching fist, stared at the batter that was slowly returning to its original shape, a light flashing in his eyes, and quickly thought about something.

There is no doubt that it is obviously possible to make shields from non-Newtonian fluids.

However, it is absolutely impossible to use the flour of the moment to make a shield as a means of survival, which is too child's play.

This is only a rudimentary test, and then it will be used as a basis for continuous improvement to experiment with more denser, more inherent, and more characteristic non-Newtonian fluids.

Try to use spells in it, combine the technology of the modern earth with the technology of the current wizarding world, and let a shield play the role of "one plus one is greater than two".

"Then next, ......" Richard stared at the flour shield in mid-air, and had a plan.

......

For many days to come, Richard was busy, experimenting with various materials.

There are many types of non-Newtonian fluids, far beyond a person's understanding, in addition to batter and chewing gum, such as tomato juice, apple pulp, potato pulp, melted chocolate, thick sugar water, condensed milk, egg white, and surimi, minced meat and other food materials.

Of course, non-Newtonian fluids are not all food.

In addition to eating, the concentrated solutions and suspensions of polymers are generally non-Newtonian fluids, including but not limited to polyethylene, polyacrylamide, polyvinyl chloride, nylon 6, PVS, celluloid, polyester, rubber solutions, etc.

In addition, there are some building materials, including but not limited to mud, coal-water slurry, ceramic pulp, pulp, paint, ink, etc.

What Richard had to do was to find and create as many non-Newtonian fluids as possible, and through a large number of experiments, to determine which non-Newtonian fluids worked best, which non-Newtonian fluids combined with spells the most perfectly, and which non-Newtonian fluids were more cost-effective......

Ultimately......

......

Many days later.

Spell Proving Ground.

Richard stood, and on the ground next to him, placed a square container filled with a viscous liquid that looked like ink.

This is not a separate substance, but a mixture, in addition to some common materials such as grit and toner, there are also some materials for demonic creatures, such as the blood of a ground bear and the bone meal of a black-headed raven.

Eyebrows twitched, and Richard crouched down, looking at the liquid. Then he stretched out a finger, inserted it into the liquid, and pulled it hard to bring out the long filament. The filament is drawn to a very long length without breaking, and it is full of viscosity.

"So ......"

With a flick of Richard's finger, the free energy element in his body surged, and the spell was released, causing the liquid to break away from his finger and fly into the air, turning into a thick round shield. Then a yellowish liquid resembling grease grows and coats the surface of the shield—the power of the spell.

Spells and non-Newtonian fluids are a double combination.

"Whew-"

Richard stood up, took a deep breath, adjusted his physical condition, controlled the air to protect his fist, aimed at the shield, and punched hard.

"Bang-"

The shield made a loud noise, very soft.

Richard could feel that the force contained in his fist was forcibly dispersed the moment it touched the shield. The then dispersed force hits the body of the shield, causing the shield to quickly harden and be completely removed.

Richard withdrew his fist and saw that the shield quickly returned to its original state, undamaged.

Richard blinked, no surprise at this, because this was only the easiest test, and the second test was to be performed.

His lips slowly opened, and with a wave of Richard's hand, an ice pick was born. The icicle didn't seem to have much power, but it was fast enough to fly out like a bullet, shooting at the shield with great momentum and penetration.

"Poof—"

The ice pick came into contact with the yellow liquid on the surface, tearing the film of the yellow liquid quickly and slamming it into the shield.

After that, there was a "bang", on the hardened non-Newtonian fluid, it crashed and shattered.

Richard was not surprised by this, and conducted a third test.

Stepping back a certain distance, Richard bombarded with a plastic fire-like spell.

"Boom, boom!"

After a few spells, the shield was slightly damaged, but it blocked all spell attacks almost perfectly.

So......

Final test!

"Da Da Da ......"

Richard stepped back, this time far enough away to prepare to attack with the strongest spell, the Salt Shattering Armor Bullet, to test the effect of the shield.

You can also see which one is stronger, the sword for attack or the shield for defense.

Who is it?

Take out the spell salt, and Richard casts a spell to control the spell salt particles from flying out and attaching to the surface of the shield. Then he recited the incantation for a long time, and after preparing for most of the day, he raised his hand and blasted out a gorgeous spell barrage.

"Boom!"

The violent tremors that had occurred before reappeared, and the waves and shockwaves whistled and spread out in all directions, violently blowing through Richard's body.

Waiting for the sound to subside, Richard squinted at the shield. I saw that the entire shield, under the destruction of the spell salt, became shattered, and less than half of the volume remained on the front, obviously exceeding the limit of what it could defend.

As I got closer, I could see that the back of the shield hadn't even preserved a quarter of its volume—it had broken under the stress of the armor shattering bullet.

In the contest of swords and shields, it is clear that the sword wins - the sword pierces the shield!

In this way, maybe the shield can be thickened, and when it comes to defense, it can change into a more powerful shape in time to defend, but the sword can also become stronger. In addition, under the principle of armor shattering bullets, even if the shield is thick, it can also cause damage.

So...... Will the shield always be weaker than the sword?

Will it?

Not necessarily.

Sword and shield, offense and defense, are like two sides of the same coin, no one side will always win, and no side will always lose.

The sword can rely on the principle of armor shattering bullets to deal damage without breaking through the shield. So doesn't the shield have a similar means to safely defend against an unstoppable attack?

For example...... Reactive armor.
