Tian Xu surfaced, pillowed his hands behind his head, and checked the improvement process of olfactory imaging from beginning to end again, but still found no problems. He was not discouraged, but changed his thinking angle, called out Dan Ling, who was sleeping in his heart, told Dan Ling the ins and outs of the matter, and finally asked: "Xiao Ling, help me think about it, what is the problem?"

Dan Ling agreed with an "um" and said, "If I were a Saint Realm Immortal, what would I do when I was invisible?" He thought about it, and actually came from Tian Xu's body to the outside of his body, and appeared on Tian Xu's belly floating on the water.

What Dan Ling showed was a small person more than an inch tall, with a translucent body, jumping twice on Tian Xu's belly, repeating what he had just said: "If I were a Saint Realm Earth Immortal, what would I do when I was invisible?"

The villain's body appears and disappears from time to time, trying to simulate the state of invisibility in the Holy Realm, but he can't do it well, the aura in his body is a little less, and it is a little difficult to condense the "skin" of invisibility.

Dan Ling scratched his ears and cheeks for a while, suddenly bent down and stretched out his hand, grabbed down, and actually put his hand into Tian Xu's lower abdomen, grabbed Tian Xu's Jin Dan, and pulled Jin Dan out of Tian Xu's lower abdomen. Tian Xu felt a pain in the dantian, and before he could react, he saw his golden pill being pulled out by the danling. It was the first time he had seen his own Jin Dan with his own eyes, and it was estimated that very few other Ning Dan Realm cultivators had seen his Jin Dan.

The first Ning Dan Realm cultivator he had ever killed was Hu Dawei of the Tiger Gate, and he dug up his golden pill, and Hu Dawei's golden pill was red. Later, there were more and more cultivators in the Ning Dan Realm who were killed by him, and quite a few of the enemy's Jin Dan were dug out by him, those Jin Dan were basically spherical, the color was mostly red, and a few were white, according to the assessment of the opponent's combat power, the strength of the White Jin Dan Ning Dan Realm would often be stronger, and in the same level, the volume of the Jin Dan would also be larger. And if Jin Dan has other colors, or is variegated, the combat effectiveness will be a little worse.

The shape and size of his own gold pill, he had a clear understanding through his inner vision, and the color was not very clear, as if it was really golden. He originally thought that gold was an illusion brought about by inner vision, but after seeing it this time, he found out that his golden pill was really golden, and he had never seen others have a golden golden pill like him.

His golden pill is a legendary alien flying saucer-shaped, with a convex middle and flat edges, one side is relatively smooth, and the other is very prominently raised. The diameter is slightly smaller than that of a regular discus, and the thickness is more than twice that of a discus. The golden color of the whole body is domineering.

Dan Ling and Tian Xu were one, and his act of pulling Tian Xu's Jin Dan out did not make Tian Xu feel nervous, he just lay quietly on the water and watched Dan Ling's performance.

I saw that after Dan Ling pulled Jin Dan out, he jumped and jumped on top of Jin Dan, and his body gradually sank into Jin Dan. Dan Ling is the spirit produced in Jindan, and Jindan is one and two, two and one one, Jindan is his body, at this time he and Jindan are one, and it is natural.

Tian Xu's Jin Dan is not as hard and smooth as other people's Jin Dan, but soft and deformable, after Dan Ling entered Jin Dan, the Jin Dan slowly deformed, the body gradually elongated, and one by one the head, hands, feet and limbs grew, and finally became the shape of a villain. The villain said: "My aura is insufficient just now, so I'll be separated from you for a while to demonstrate how the body made by the aura is invisible." Listening to the tone and tone of his voice, it was obviously Dan Ling who had been talking to Tian Xu.

Tian Xu had no opinion on Dan Ling's words, and in this Medicine King Dou, he was not afraid of any danger, and said, "Okay, Xiao Ling, can you completely simulate the stealth state of the Holy Realm?"

Dan Ling replied, "There shouldn't be much of a problem. I am now the same as the Sanctification Realm, a body made of pure aura, and what they can do, I can certainly do. ”

As he spoke, Dan Ling flew up from Tian Xu's belly, stayed in the air more than two feet high for a while, and then flew to a distance of twenty meters, and the image gradually became illusory, and then became invisible and invisible.

Tian Xu hurriedly carried out the improved olfactory imaging, searched the surroundings, and soon found Dan Ling's figure more than thirty meters away on the other side. Most of the aura in his body was taken away by Dan Ling, and the remaining aura was no longer enough to support him to fly or cast spells, so he used the Sun Chasing Technique to step on the water with the strength of his physical body, and strode towards the direction where Dan Ling was.

Seeing Tian Xu chasing after him, Dan Ling knew that he had been discovered, so he immediately changed his stealth method and fled quickly. Dan Ling and Tian Xu have the same mind, and they can know what Tian Xu sees in the olfactory imaging for the first time, and constantly improve the stealth method according to the appearance, making Tian Xu's tracking more and more difficult.

However, although Dan Ling's stealth is getting better and better, he still can't escape the tracking of Tian Xu's olfactory imaging. In the end, Dan Ling reduced the external observation to the limit, and made the neutralization effect of the "skin" on the energy fluctuations in the body also the strongest, his stealth has basically reached the extreme, and Tian Xu has been difficult to find the location of his stealth in time, and it is necessary to switch and compare frequently between the two olfactory imaging to find his location. However, Tian Xu was still able to discover the existence of Dan Ling in the end.

In the end, Dan Ling returned to Tian Xu's side, landed on Tian Xu's open palm, and said with some dejection: "It seems that you have done it to the extreme, you can still find me, it seems that there should be no problem with your olfactory imaging, are you worrying about yourself and scaring yourself?"

Tian Xu shook his head and said, "No, there must be a problem." ”

He had a heart-to-heart with Dan Ling, and recalled in detail the stealth process that Dan Ling had just done, as well as the process of discovering the other party, and said: "There should be a problem, let me think about it again." ”

His body could not levitate in the air, and when he stopped to speak, he fell down, and finally landed in the water, resuming his original position of lying on the water, leaving Dan Ling to jump and play on his belly alone.

The current Dan Ling couldn't help much, but Tian Xu was in no mood to pay attention to him, let him play there at will, and he returned to his state of thinking. He had already vaguely felt a hint of the key to the problem, but he hadn't touched it yet.

In this way, Tian Xu lay on the water for almost half a day, and then he asked Dan Ling to play the role of the opponent of the Holy Realm twice, playing hide and seek with himself to find the problem.

Finally, in the process of playing hide and seek for the last time, Tian Xu suddenly shouted: "I know!"

The spirits of Dan Ling and Tian Xu are always connected, after Tian Xu thought of the problem, Dan Ling also understood it for the first time, Tian Xu saw Dan Ling's figure swaying in the distance, and then disappeared completely. Because he could share Dan Ling's field of vision, Tian Xu could clearly feel the true location of Dan Ling, but his olfactory imaging could not find Dan Ling's figure in a theoretical position at all, even if Dan Ling was close to him a meter or two, he couldn't find it!

Finally got to the root of the problem.

When Tian Xu was analyzing the stealth method of the Holy Realm before, he subconsciously ignored the possibility of the other party recognizing the impact of external observation on the environment. This is where the uneasiness in his heart comes from.

Since he was able to ascend through the tribulation and condense the aura body, then the understanding of the aura in the Holy Realm would definitely not be below him. Similarly, since the Saint Realm has an innate stealth ability, it will of course take this stealth ability to the extreme, without leaving such a hidden danger.

And the solution to this hidden danger is really the simplest compared to a saintly realm immortal. Since the Immortal of the Holy Realm can use the method of neutralization to hide his own energy fluctuations, of course, he can also use the same method to compensate for the five senses that are absorbed by himself, simulate the five senses that are absorbed because he feels the information of the outside world, and re-release them, so that he can deceive the detection and scanning of others.

Even if a certain Saint Realm Earth Immortal is not aware of his impact on the surrounding environment at the first time, he will quickly find the difference from others and correct it in time, otherwise this person is the only person who does not have the ability to stealth among the Earth Immortals, and all his privacy may be exposed to other Earth Immortals because of this. If the surrounding earth immortals are all friends, it is better to say, as long as one enemy discovers this problem, then this earth immortal with defective stealth ability will basically live to the end.

If Tian Xu only relied on the initially improved olfactory imaging ability to go to the position immortal, even if his combat power was enough to deal with the enemy, but he was like the earth immortal he just mentioned, he was completely unable to find the invisible enemy, which was equivalent to leaving the undefended back to the enemy, and the danger was self-evident.

Although he found the problem in time, he still didn't have a solution to the problem for a while, it was equivalent to returning to the same place, the previous ten days of hard work were all in vain, and he had to start from scratch to find a way to deal with the stealth of the Holy Realm.

Of course, Tian Xu's improved olfactory imaging, although it can't solve the problem of stealth in the Holy Realm, it is not completely meaningless, at least his olfactory imaging covers a more complete sense than before, and it has become much more sensitive.

So how should we solve the problem of invisibility in the Sainthood Realm? Tian Xu's thinking finally returned to the seed of the realm that Xu Jingyi planted in his sea of consciousness mentioned by Ziyan, that is, that small space.

"It seems that what we have to do later is to feel," Tian Xu said to himself, "I'm a little tired." He soaked in the water for a day, and wanted to go to the shore for a walk, move, and see how Ziyan practiced the three knives of Ku Ding.
