.BN Uc vva F @ :1o} z - ......" Pandora looked over, flashed her eyes at Richard, and explained, "I didn't break the things, they broke themselves, and it doesn't matter to me." ”

I know it's none of your business, but can you hide your excitement?

Richard thought to himself, and before he could say anything, he heard Pandora ask anxiously, "This broken glass, you're useless, right? If it's useless, then I'll put it away?"

"This ......"

Well, you really don't hide it at all.

But...... What's the use of collecting so many glass shards?

Richard thought and didn't answer for a long time, Pandora looked over again and asked carefully, "No...... No, are you useful?"

"It didn't work. Richard said helplessly, "You take it." ”

"Oh, that's good. "Pandora quickly collected it, and how high the positive gender lift was.

Richard couldn't help but shake his head, and the next moment he walked to the experimental table.

Sitting at the circular lab table, Richard pulled out scrolls, ink, and quills and quickly jotted down what had been tested for spells.

After the record, Richard glanced at the difficult quill pen in his hand and wondered if he could take some time to try to make a fountain pen.

Of course, this thought also flashed through him, Richard dried the scroll, put it away, and then got busy with another more important thing - to increase the lower limit of his strength, but not in terms of attack, but ...... Defensive aspects.

To put it simply, combat is nothing more than attack and defense, sword and shield.

Spell Salt is now made to give him a sharper shield, and he needs a stronger shield to match.

All along, his defense has been a weak point, in addition to condensing air to make an air shield, it is to condense air to make an air wall.

In the face of some ordinary people, apprentice-level and even weaker wizards, they may be able to deal with it, but in the face of more powerful wizards, even the existence of Somen, Mu Coni, and the sloppy man in blue, it has the taste of being a mantis arm.

When he first met Somme and Mukne, he didn't think about defense at all, because he couldn't defend at all, so he would desperately grab the first move.

Not long ago, when he met the murderer of the university scholar Surates, the sloppy man in blue, he didn't think about defense at all, and he couldn't defend against it either—he didn't have the confidence to defend against any attack, so he would succeed in one blow and retreat immediately.

All along, because his attacks were far greater than his defensive capabilities, he took the "agile" route, attacking the enemy like an assassin and trying to kill the enemy with a single blow. If this is not possible, it will retreat, try to dodge the enemy's attack, and then try to attack again, killing the enemy in one hit.

This method can't be said to be bad, in fact, he prefers this method - this method has a smaller combat consumption when defeating the enemy, and it can ensure that one person can deal with many people of the same level, which is much stronger than the way of standing on the pile against the bombardment.

But then again, just because the stake fighting style may be backward doesn't mean it's without merit.

According to his previous analysis, the reason why there is this way of fighting is the reason why wizards are excessively pursuing safety. Perhaps out of confidence in their decades of accumulated strength, wizards would rather run out of mana and use spells to split the battle than rely on a risky and unconventional act to win or lose a battle.

Therefore, the advantage of the stake combat method is that it can ensure a stable state and can effectively defend against the attack and then try to counterattack.

In this way, even in the case of a surprise attack, as long as it is not too sudden, you can defend against the first wave, and you can slowly adjust your state to the best, and then compare yourself with the enemy.

In conclusion, a strong defensive means is important.

So, how can you get a strong defensive means?

Further, how can you use science to get a stronger, if not stronger, defensive shield than most wizards at a smaller cost?

Richard had some ideas about this for a long time.

"Da ......" Richard left the lab table, ignoring Pandora, who was happily collecting the pieces of the exception, and walked to a locker in the corner of the test room.

Then bring out a bag of flour from the locker.

Flour, right, flour!

The flour in the bag was very white, had been sifted many times, and was a luxury that many nobles were reluctant to use regularly, and Richard was ready to put it to some tests to make a powerful shield in a scientific way.

I have to say that flour is a very magical thing, it can be used as food to fill the stomach, it can be used as an explosive to make a dust explosion, and it can also ...... Make non-Newtonian fluids.

Non-Newtonian fluids refer to fluids that do not satisfy Newton's experimental laws of viscosity.

In other words, there is not a linear relationship between the shear stress and the shear strain rate of such a fluid.

In other words, this kind of fluid is not an ordinary fluid, it is different from common water, alcohol, etc., and has a characteristic of "strong when it is strong, and weaker it is".

For example, this fluid appears to be a liquid, and a slow touch with your hand will also be a liquid, but when you clench your hand into a fist and hit the fluid quickly, you will not break into it as if you were hitting the surface of the water. Its special properties cause it to change rapidly when it feels the force of the fist, and then solidify, becoming a solid-like existence.

The stronger you are and the faster you hit, the harder the liquid will become, hard as bricks, stones, and steel!

This kind of property can be used to do a lot of things, some of which are strange.

For example, chewing gum boils coconut.

The specific operation method is to knead a cone with multiple pieces of chewing gum from the earth to ensure that it can stand on the table. Then he picked up the hard shell of the coconut that he wanted to break, pointed it at the gum, and smashed it down as if it were an iron cone.

Chewing gum is a non-Newtonian fluid, and the moment the coconut comes into contact with the gum, the gum exerts the characteristics of a non-Newtonian fluid and becomes extremely hard, and it will really break into the coconut like an iron cone.

In the same way, chewing gum can also open cans, soda bottles, and many other things.

Of course, just these effects, non-Newtonian fluids are not very powerful, and more importantly, they are used for defense.

Some of the most cutting-edge liquid body armor on the modern earth has begun to be made of some non-Newtonian fluids, which are very soft when worn at ordinary times, and once they are attacked by bullets and shrapnel, they quickly harden and the effect is amazing.

Richard, on the other hand, was now preparing to craft a high-tech spell shield from non-Newtonian fluids.
