The dean is starting classes again.

The content of this class is the improvement and promotion of life detectors.

In class, except for Fan Dong and Wang Feng, everyone else's eyes revealed fanaticism.

Obviously, they didn't study how to refine the life detector, and this class can be said to take them to review it again, by the way, the knowledge that has been advanced.

To be precise, it is a kind of application and perception of radiation.

Different cultivations, different species, and the radiation released will still have certain differences, and what Lin Nan is talking about now is this difference.

This content is indeed very difficult for those who can't even perceive the radiation, but Fan Dong immediately understood what Lin Nan said.

He felt that this was not something that could be achieved by manpower.

Even if it was him, he was still barely able to sense the existence of radiation, so he guided the immortal weapon to perceive.

As Lin Nan said, in fact, the research on radiation has reached an extremely nuanced level, and Lin Nan can even perceive these radiations without the need for immortal weapons.

In short, when listening to Lin Nan, it seems to be very easy, but the actual situation is not like this.

An ordinary immortal weapon is just a fifth-grade weapon, and Fan Dong has to refine it for three hours, which is enough to see how difficult it is.

"That's all for the content of the Life Probe, if there is any progress in the future, or if you have any ideas, you can come to me to discuss. ”

"By the way, these contents just now all said that my disciple Zhong Ying discovered and improved, and I can't take her credit. ”

As he spoke, Lin Nan glanced at Zhong Ying who was standing aside with relief, and Zhong Ying also returned the salute.

Lin Nan said it lightly, but others didn't think so.

Although she is your disciple and has been studying with you for many years, your disciples are now far ahead of us, which makes us feel embarrassed.

At this moment, the fighting spirit in everyone's hearts was burned.

They found that if they had been in their own family forces before, even if they knew that there were people in the outside world who could do things that they couldn't, they would not have such a strong competitive mentality.

However, when a group of refiners got together, some thoughts couldn't help but pop up in their hearts.

I will refine it faster than him, faster than them.

This mentality spreads in everyone's heart.

All of a sudden, the saber rattling ...... Can't open it.

"There's another thing, it's about another immortal artifact. ”

Hearing Lin Nan say this, everyone suddenly became interested again.

The life detector they are refining now is to understand the enemy's situation, and as for the other immortal weapons used for attack, they haven't started it yet, it's relatively simple, there is nothing new, it's just that the idea is relatively unique.

"Regarding the negative aura purification of the ancient battlefield, I don't think we can just leave it alone, after all, our time is limited, so I propose that we can refine some immortal weapons with purification power, the effect is weak, but the number can be expanded infinitely. ”

After saying this, Lin Nan stopped talking, but waited for the other people's reactions.

At this time, Yuan Jiao raised his hand.

"Please. ”

"Dean, with all due respect, there is no immortal weapon in this world that can purify the negative aura, at most it is just to amplify the purifying power released by the monk. ”

Yuan Jiao got to the point, and everyone nodded in unison.

Isn't the power of purification directly released by monks, if there is such an immortal weapon, what else do you need these monks who have learned the power of purification?

Is it true that being an alchemist is omnipotent?

"Well, no? Then I'll give another lesson, you don't mind. ”

Lin Nan knew that the teacher dragged the class, this kind of thing, was not welcome.

However, no one spoke.

Also, the teacher said that if you want to drag the class, you can still let the teacher get out.

"I made this thing yesterday. ”

Lin Nan said as he controlled the screen behind him.

It was a stick-like artifact, but at the top of the artifact, there was a small ball that was spinning.

Linnan specially made some special effects, so that when the ball was spinning, there would be a circle of ripples outside from time to time, indicating that something was being released.

"This thing can continuously release a faint purification power, I specially took it to the Royal Beast Academy yesterday to try it, and the alien beast will not react to this thing, just like seeing ordinary wood. ”

"However, the power of purification is very weak, and it takes about a thousand of these sticks to continuously release a stick of incense, which is worth the time for a Xuan Immortal to release a purification immortal. ”

"But it doesn't matter, as long as the quantity can keep up, this little thing will be able to operate continuously, and it only needs the energy of a fairy stone to work for a hundred years. ”

"The size of this thing, only the length of an arm and the width of three fingers, whether it is inserted into the ground or hidden in a tree, it is an extremely hidden existence, and there is no fear that it will be damaged by strange beasts. ”

"Next, let me explain the principle of its refining......"

Lin Nan began to start from the beginning.

This thing is actually not difficult, the reason why other people can't refine it is that no one has ever refined it, and there are no purified formations or runes in the fairy world, mainly because no one has created it.

Under Lin Nan's explanation, everyone once again learned the new runes.

This is a rune that can be purified, and it's not that no one has studied it, it's just that they haven't studied it.

However, Lin Nan researched it and shared it with everyone.

Looking at Lin Nan in front of them, they felt that what they had learned from coming to Endless Academy this time was not knowledge, but spirit.

It is the spirit of selfless dedication.

It is the spirit of daring to be the first.

It is the spirit of selflessness.

Mingxin asked himself, would they share the runes or formations they had worked so hard to research?

It's impossible, it's definitely going to be hidden, and then let everyone beg them.

But Lin Nan can do it.

Even, there is no little bit of distress, and they have something they don't understand.

I don't know why, they suddenly remembered someone.

One, a person who is only recorded in the history books.

That person has no name, but his reputation is remembered by everyone.

That man had no children, no children, no offspring in his life, but all those who went to the place where he was born would go to pay respects to his tomb.

That person can be said to be the pioneer of the development of the fairy world, it was he who made the entire fairy world develop rapidly, completely stood on the head of the fairy beast, turned over the serf and sang.

That person, called sir.

At least fifty percent of all the people in this world are descendants of Mr. disciples, or descendants of Mr. disciples.

At this moment, looking at Lin Nan's chattering appearance, they remembered the record of Mr. in the history books, and remembered the portrait of Mr. depicted on it.

It seems that it coincides with Lin Nan.
