This lord is very scientific.

"Teacher, I want protection and attack bonus."

After thinking for a while, Lin Ke thought of the answer.

As soon as the words came out of his mouth, Aof frowned.

Sometimes this is the case. Children don't know how to choose in certain situations and always want to have it all.

But this is the time for parents, teachers and others to play their role. They must teach children some of the most basic common sense theorems.

"Xiao Linke, you have to know that the Lucky Flower is quite effective in calming the mind and promoting sleep, but it cannot make people energetic."

Auf said earnestly.

This sentence is a common saying in Nasenger, which roughly translates to "You can't have your cake and eat it too."

Lin Ke nodded: "Teacher, I know."

However, these common theories often cannot represent physics, let alone the truth itself.

Common sayings and truths are only useful in certain situations and may be misleading in many other cases.

For example, you can't have your cake and eat it too, teaching people not to be too greedy and to make choices.

But sometimes, when it is obvious that you can do better and get the best of both worlds, it would be a pity to give up on one side.

You can't have your cake and eat it too, that's because the fishing nets used to catch the fish are not strong enough.

If you switch to barbed wire, you may be able to have both. If you switch to titanium alloy or diamond, you may be able to have both. If you switch to the legendary enchanted mithril gold net, you can have both, not to mention fish and bear's paws, fish and dragon.

So Lin Ke still wants to have both.

Attack and defense, never give up.

"As long as you know."

Aof nodded, and he also remembered that his disciple was not a real child, at least in terms of intelligence.

"but……"

However, Auf just agreed with Lin Ke and smiled bitterly: "What I have prepared for you is the 'Inertial Crash' with attack bonus, and the other is 'Resistance Shield'. Both of them use the science of strength. Research."

Aof had studied many skills at the beginning, but he carved the most suitable skills into the skill slots, and the rest became his private collection.

According to Lin Ke's understanding, professionals can study both magic and skills at the same time, and skills can be inscribed on skill slots.

Magic is like a sword in the past life. Everyone knows how to make it, and it can be made if the conditions permit. So if you use lightning, fireball, or the elements, others will know what magic you are going to release.

But skills are like special guns and ammunition. Generally, others don’t know the skills you develop yourself.

Of course, some professionals have shown their skills to outsiders, so they are not unique secrets.

Therefore, many people prefer to study skills rather than delving into magic, and therefore have developed many skills.

However, everyone's skill slots are limited, so only appropriate skills will be selected and carved into the skill slots.

Just like Off, his skill slots are all full, but there are still many skills that have not been written in. Those skills will be released when they are usually used.

Releasing the ordinary skills you have researched is the same as releasing magic. It consumes more money and takes longer. It is not as fast as the skill slots that are almost instantaneous and consumes very little.

"Actually, apart from thunder and lightning, what I study the most is the science of power."

Aof explained and looked at Lin Ke: "Or do you have any ideas? Let's think about it together."

Lin Ke can always surprise him, this is what Aof discovered during this time.

Sure enough, after listening to Off's "inertial collision" and "resistance shield", Lin Ke said directly: "Teacher, have you heard of air pressure and streamlines?"

Lin Ke was also thinking at this time that he must ask Aofu to teach him the other two skills later!

Inertial collision...couldn't it develop into a world-destroying and clinging support in the future?

As for the resistance shield... Auf told him before that the force of resistance is actually very similar to gravity and repulsion.

Mom, this is the predecessor of Shinra Tenzheng!

Lin Ke was almost moved, but luckily he restrained himself. He could learn these later, or even study them himself.

But now, it’s better to choose the most suitable one.

"Air pressure? Streamline? What is this?"

Off was puzzled.

Lin Ke smiled and started to make up random things: "I discovered this when I was a child..."

Then after telling and explaining how he discovered "air pressure" and "streamline", Lin Ke continued: "...So, I named them air pressure and streamline."

"Well...you mean, someone is running too fast and passes in front of you, and you feel the air behind you pushing you to the other side..."

Aof's shocked expression was like that of a disheartened bride or a speechless scumbag. In short, it was very strange:

"As for the streamlined body, you said that you experimented with the 'best' shape by pointing your hand at the water flow in the water and experimenting with different shapes with your fingers..."

Aof felt that he was worse than a child after living for hundreds of years!

Air pressure! streamline!

This is air pressure, this is streamlined? !

yes!

Why didn't he think of that?

He is a star-level professional, which is simply embarrassing!

Off began to doubt himself.

"Yes, teacher. For example, in the kitchen downstairs, when the wind outside blows fast and the air pressure is low, and there is a lot of smoke in the room and the air pressure is high, the black smoke is easily 'pressed out' by the chimney and windows."

Lin Ke once again gave an example of air pressure.

Auf listened to Lin Ke's example, his eyes flashed with electricity, and he even made a "buzzing" sound.

His brain was rapidly thinking, recalling, and simulating the situation Lin Ke was talking about.

After a while, the lightning in Aof's eyes gradually disappeared, and he opened his mouth not to admire but to sigh.

Lin Ke couldn't help but be stunned: "What's wrong, teacher?"

Aof smiled and shook his head: "I'm thinking, if I had met Garose and Furlong two hundred years ago and let them give birth to you, maybe I would be a legend now."

Lin Ke couldn't laugh or cry: "At that time, their parents and my grandparents who have passed away long ago may not have been born yet!"

Garose was only in his thirties, and Furlong was only in his twenties. Both of them were very young.

Garose only met Auf by chance. Otherwise, as a young nobleman from the countryside of Nassenger, he would not even be able to touch Auf's clothes.

"Haha, Xiao Linke, since you already have an idea, I will teach you how to inscribe skills on skill slots tomorrow."

Aof smiled and touched Lin Ke's head. What he just said was just a joke.

After Lin Ke gradually opened his heart, he sometimes learned to be humorous.

Although Lin Ke didn't think it was funny.

“Quack quack!!”

Suddenly, a loud bird call came from the side, and it was Little Lucky's call.

It seemed that he was dissatisfied with being woken up by Lin Ke and the others.

"Xiao Linke, then you can sleep."

Aof smiled kindly. The dark and windy night was a good time for experiments. Later he was going to verify many of the things Lin Ke said.

If those experiments were successful, perhaps he would get some amount of "learning" feedback.

Because this is Lin Ke's discovery, just like Lin Ke taught him.

[Truth Researcher] The feedback on "learning" is not as good as that on "research", and the amount of feedback is very small.

However, accumulating little and working hard is what Auf has been doing, otherwise he would not have become a star.

"Good night, teacher."

Lin Ke bowed to send Off, and then put the weak little Lucky to sleep.

Sensing the increasingly powerful vitality in little Lucky's body, Lin Ke also fell asleep with peace of mind.

…

A night of silence.

The next day, Lin Ke got up early and prepared to see the trial production of Azan Paper Mill.

However, at this moment, he suddenly remembered that there seemed to be something he had forgotten yesterday?

Never mind it, it's probably not important.

Lin Ke hurried downstairs, casually asked two guards to leave, and didn't bother John. The guy was very busy these two days.

Of course, Lin Ke himself was very busy, or everyone in the castle was busy.

Antova and Furlong were busy enjoying life, tea and beauty, the servants were busy working to support their families, and Lin Ke was busy becoming rich and powerful.

So you see, both the rich and the poor are busy, no one is idle, everyone is the same.

But when he came to the corridor, he saw a hunched figure with a sleepy face.

"Master Lin Ke!"

The figure screamed in surprise when he saw Lin Ke, and limped over.

It was the hunchbacked Grandma Xisai!

correct! Almost forgot!

Yesterday, he arranged for Grandma Xisai to come to the castle.

"Master, this old woman rested in the guest room all night and broke a total of five black toilet stones, an elm bed frame and three layers of goose down quilts."

Behind Grandma Xisai was a dark-faced leader of the guard team.

Lin Ke raised his eyebrows when he heard this and looked at Grandma Xisai: "Are you trying to make gunpowder? Are you knocking out the saltpeter from the toilet and the sawdust from the bed frame?"

"how do you know?"

Although Grandma Xisai didn't know "gunpowder" and "saltpeter", she understood what Lin Ke meant. After all, she heard Lin Ke say "gunpowder" yesterday.

Good guy, it is indeed gunpowder!

"Where did your sulfur come from? It's just another thing that doesn't smell very good." Lin Ke became interested in Granny Xisai: "Also, what else do you want? Let's talk while we walk. ?”

"Yeah, yeah, yeah!"

Grandma Xisai smiled brightly, her eyes narrowed into slits, like the wrinkles around her, like vertical and horizontal ravines.
