Just when he was at a loss, Ling Ruo felt that there was a way for him to try.

"Li Daoyou, can you take that bloodline positioning secret technique, and the part that you have written down, can you expand it?" Ling Ruo asked.

Li Shen said: "Yes, yes, but can the incomplete exercises work now?" ”

Ling Ruo said: "Now treat the dead horse as a live horse doctor, and I'll try to use the Heavenly Eye to deduce if I can complete the exercises." ”

Now there is no other better way, so Li Shen took a blank jade slip and extended all the places in his memory about that exercise from the sea of knowledge.

Ling Ruo got the jade slip, quickly reflected in the sea of knowledge, and then began to pinch his fingers and calculate.

If it was in the Heavenly Immortal Realm before, she wanted to complete a mortal non-streamed exercise, it would be a matter of different kinds. However, this is undoubtedly sad for her now.

However, she had seen the woman in white use that bloodline secret technique with her divine sense, and based on this, combined with that incomplete technique, it would be much easier to complete it.

When dense fine sweat began to ooze from Ling Ruo's forehead, she finally stopped.

"Is it done?" Li Weitian carefully wiped the sweat from her face and asked.

Ling Ruo nodded, added the deduced part into the jade slip, and then handed it to Li Shen, and said, "Li Daoyou, your cultivation is high, this secret technique is performed by you, and the success rate will be higher." ”

The secret technique of bloodline positioning is not 100% guaranteed to be successful, and the bloodline connection between the two, as well as the level of cultivation of the caster, will affect the success rate.

Li Shen took the jade slip with some surprise.

Tianyan treasure, although he has not used it, he has also heard of it, is it so powerful? It can actually complete the exercises! Even if it was just a small secret technique with simple functions, if he wanted to complete it, it was not something that could be done casually, even if he deduced it himself, he might not be able to deduce it, but Ling Ruo was able to do it in such a short period of time!

However, now that time was pressing, he couldn't think too much, and he quickly reflected that exercise into the sea of knowledge.

Li Weitian took the initiative to bite his finger and squeeze out a little blood.

Li Shen used the secret technique he had just learned, and the drop of blood on Li Weitian's finger turned into a faint blood mist and went up, but suddenly turned a corner and flew towards the stone that Ling Ruo thought was strange before.

However, just as the blood mist was about to hit the stone, it suddenly turned around again and flew backwards.

It's just that this blood mist didn't last long, and it has dissipated at this time.

Li Shen looked at the strange trajectory of the blood mist, puzzled: "What's going on?" This blood mist was indeed flying towards the place that Ling Daoyou had thought was strange before, but why did it suddenly retreat again? ”

A light flashed in Ling Ruo's mind, and he became excited, "I know! It's a reflex! No wonder I find it weird! ”

She pounced, carefully touching the place where the blood mist had just touched, but she still didn't feel anything different.

And Li Weitian also reacted: "You mean, this position on the stone is not what we see with our naked eyes now, but the result of other things, reflected and revealed, right?" ”

Ling Ruo nodded, "Not only what you see, but even the feeling you feel when you touch it is also the result of reflection." This reflection is to completely copy the A and cover it on the B place, so that the B part becomes exactly the same as the A place. Using this method to hide the entrance of a cave, a doorway, etc., is the least easy to detect! Because it's not a simple illusion, let alone breaking it, even if you perceive it, it's not easy to detect! ”

It could even deceive Ling Ruo's divine sense, so even if Ling Ruo opened his divine sense, he couldn't see what the real appearance of this covered stone face was.

However, what is fake is fake, and what is reflected is a sense of disobedience after all, although Ling Ruo's divine sense has been deceived in the past, it still accurately captures this sense of disobedience.

If it weren't for Ling Ruo's divine sense, even if Princess Furong and these Jindan Yuan Masters came, they wouldn't have noticed that there was a problem here.

After seeing that the blood mist was indeed drifting in this direction, Li Shen now believed that there was something wrong with the stone, but he pushed it on the stone face, but he couldn't push it at all.

"Is there really a hole hidden here? Why can't I push? ”

"The piece you pushed was copied from another place where there was no hole. There could be a hidden hole underneath, or it could just be something carved into the stone face. Either way, you have to break it first. Li Weitian said.

The two men both looked at Ling Ruo.

If Ling Ruo could sense that there was a problem here, he could only hope that she would solve it now.

And Ling Ruo did live up to their expectations.

After understanding what was going on, it was impossible for this little trick to continue to deceive Ling Ruo's divine sense.

Ling Ruo opened his Divine Sense again and shrouded it on the stone face.

Although these stones are as smooth as jade, they are not static, and there are some lines on the surface, while the natural lines are coherent and connected.

Ling Ruo quickly outlined the violating parts in the sea of knowledge, and quickly identified the problematic parts.

It was a rectangular area, literally like a hole or door that could only be entered and exited by one person.

Seeing that Ling Ruo didn't move for a long time, Li Weitian said worriedly: "If it doesn't work, don't force it, let's think of another way." ”

Ling Ruo hooked her lips and smiled, "It's not that difficult." Reflection is like looking through a mirror. If you want to see what you want in the mirror, there is one thing that is important! ”

Li Weitian's eyes lit up: "It's the angle!" Depending on the angle, the image in the mirror will be different! If you want to see the scene you need, you need to keep adjusting the angle! ”

"That's right!"

The reflected scene is not the real thing, and there will still be a flaw, and this flaw is the change in the size of the part that violates the harmony from different angles.

What maintains the reflection must be something like a treasure, and the closer you are to this treasure, the smaller the difference in discord and the greater the opposite.

In this way, Ling Ruo quickly located the approximate location of the treasure, and then, condensed his divine consciousness into a needle shape thinner than a hair, and stabbed it fiercely in that direction.

The three of them only felt a flower in front of them, and a black hole appeared out of thin air.

But before they could rejoice, the hole was gone.

"This, this ......" This development made Li Shen incoherent.

Although the true form of the cave had only appeared for a short time just now, Ling Ruo could see very clearly that there was an octagonal mirror hanging from the place where his divine sense had just pierced.

It should be this octagonal mirror, which plays a reflective role.

If you want it to stop, you can't just prick it with the needle of your sense, you have to cover it with something. Yes, it's been too short to appear.

After thinking about it, Ling Ruo had a solution.
