"Are you old and have a bad brain, this is a detection device, who told you to add an explosion function to it?"

"Isn't it common knowledge that your brain is broken, and the detection device will explode?"

"Common sense, your sister, this thing was only proposed three days ago, and now the refining spectrum has not been drawn, you tell me common sense?"

"I don't care, if I don't explode, I'll do it. ”

"Don't do it, get out of the way, the demolition team needs you more. ”

"Old Ma, believe it or not, I'm going to blow up your hometown while you're not at home. ”

"Oh, I knew you were coming, so I removed everything from the house before I went out. ”

"Damn, no one can stop me from exploding today. ”

Three days have passed.

Compared to those students below the Immortal Monarch who were constantly learning more advanced refining techniques, these Immortal Venerables and Immortal Monarchs, who numbered more than a thousand people together with Lin Nan, were studying new immortal weapons day and night.

An immortal weapon that can replace the divine consciousness and scan without anyone noticing, in order to allow people to detect the internal situation of the ancient battlefield.

As long as the energy is instilled, it is able to fly on its own, and the monk does not need to use the divine sense control, but uses another immortal weapon to display the image.

Other weapons or something, let's not do it for the time being.

Lin Nan's suggestion to them was to make an immortal weapon that could judge the strength of the other party.

Everyone understands that if this thing comes out, they will not even need to be present in person in the future to know the number of people in a city and how the strength will be divided.

As for now, the difficulty they face is how to judge the strength of the other party without divine sense.

If you can see it with the naked eye, then what else does it take to do it?

"Lao Fan, it doesn't matter if it will be discovered or not, first make the most important function, and then consider the issue of security. ”

"To put it lightly, without divine sense, how can you see the other party's cultivation?"

A question directly bothered Fan Dong for three days.

And sitting opposite Fan Dong, an old man who looked about the same age as him sat there, and the two of them stared at each other for three days.

"Wang Feng, do you have any suggestions?"

"Just kidding, you didn't even think of it, Lao Fan, what is the use of asking me, I still learned my alchemy from you. ”

"I had a little bit of an unrealistic idea that I didn't know if it would work or not. ”

"It doesn't matter if he can do it or not, didn't Lin Nan say it, if you have any ideas, make them, and change them if they can't do it. ”

"That makes sense. ”

Just do it, Fan Dong took the lead, Wang Feng followed, and the two went directly to the warehouse of Endless Academy.

The materials were provided by Endless Door, and they didn't even pay the tuition.

However, all the materials that can be used are not more than six grades.

Everybody knows why.

Now it is only in the research and development stage, and the grade of the material is important, but if you want to achieve different functions, it is not just the material.

The most important thing is to see how well they understand the refining runes, as well as ...... The product of a combination of multiple side hustles.

The number of refining runes is limited, and they can't achieve all the functions they want to achieve, so the refiner will start to learn the formation or spirit rune, wanting to integrate the effects into the immortal weapon.

The two people who quarreled in front of him were refiners and array mages, and one of them, Sun Wen, a seven-grade refiner, was very obsessed with immortal weapons that could explode, thinking that when fighting, the sudden explosion of immortal weapons could catch the other party off guard.

And that's exactly what happened.

The immortal weapons he refined were not sold well at all in the immortal world.

It's obviously a consumable, but it's more expensive than ordinary immortal weapons.

Fan Dong has been an eight-rank refiner for a long time, and in addition to refining weapons, he has also learned formations and spirit runes, and they have all reached the level of eight-rank.

All of this is just for the sake of refining weapons.

After receiving a large number of first-grade and second-grade ores, Fan Dong was planning how to explore in his mind.

If you want to see through the strength of the opponent, the only way is to surpass the strength of the opponent's divine consciousness, so that you can see through his divine consciousness and immortal power strength, so as to judge the strength of the opponent.

This is the mainstream method that has been enduring in the fairy world.

And the partial one, it's not nothing, it's just not very accurate.

Seriously, when being probed, unless the strength is stronger than the other party, it must be detected by the other party.

So, apart from divine consciousness and immortal power, what other ways can reflect the strength of a monk?

The answer is the flesh.

Although the increase of immortal power on the physical body is actually not high, no matter what, as long as you embark on the path of cultivating immortals, the physical body will definitely continue to increase.

Therefore, Fan Dong felt that if he could detect the blood qi in the other party's body, he would be able to roughly judge his strength.

However, in this case, it will also cause a certain amount of error.

Some monks with higher talent have improved their immortal power realm very quickly, but their physical bodies can't keep up.

But the object of their detection now is not a human, but a strange beast.

These alien beasts all rely on their physical bodies to fight, that is, if they can detect the blood qi, they can judge how strong these alien beasts are.

Thinking about it this way, Fan Dong felt that his thinking was right.

So here's the problem.

Coming to the refining room, Fan Dong and Wang Feng looked at the neatly arranged materials on the ground, and once again fell into thought.

Accustomed to using their Divine Sense to probe, they now subconsciously use their Divine Sense whenever they think of probing.

This is a habit that has been cultivated for millions of years, and it is really difficult to change.

"Flesh ......"

"Flesh ......"

"Divine Consciousness ......"

"Fairy Power ......"

For a moment, Fan Dong continued to think.

If it is only with the naked eye, it will definitely not be visible, that is, there needs to be something that cannot be sensed by a person to replace the divine sense, so as to be able to detect the strength of the other party.

This kind of function is not nothing, the formation and the spirit rune have a relative effect, some advanced formations, you can judge the strength of the monks who enter it, and activate the corresponding function.

Thinking of this, Fan Dong directly took out the refining furnace and began to refine this immortal weapon.

There is no need to consider the appearance, only how to detect it, Fan Dong's efficiency is very high, and it takes less than half a column of incense to refine.

The refining furnace was opened, and a round ball fell into Fan Dong's hand, and after activating it with immortal power, he directly scanned Wang Feng, who was watching quietly.

"I said, even if I haven't cultivated, I can feel that something has just passed over me. ”

Wang Feng's role is that of a guinea pig, and he directly made a positive evaluation of the immortal weapon refined by Fan Dong.

"Also, isn't our requirement to be able to detect without immortal power? isn't your detection method just to spend more immortal power and divine consciousness consumption to know the opponent's strength, and the eight-rank formation is engraved on it, so you can figure it out. ”

“...... Still have questions?"

Fan Dong was not angry, he also realized the problem, it was indeed not ordinary.

"Otherwise, if you look at this thing, it might give you a little inspiration. ”

At this time, Wang Feng suddenly took out a palm-sized square immortal weapon and put it in Fan Dong's hand.

"What is this?"

"Your Fan family has its own communication immortal weapon, remembering that you didn't pay attention to this thing, this is refined in the Endless Gate, and it doesn't need to be activated by immortal power to achieve the effect of communication. ”

“...... Why didn't you take it out earlier?"

"It's not like I didn't expect it. ”
