Everyone was overjoyed, they all knew that Gu Tiancheng was carrying the artifact of the Imperial Qiankun Ding, but they never thought that one day they would be able to enter the Imperial Qiankun Ding and have close contact with the famous artifact in history.

Entering the Imperial Qiankun Ding, Nika helped settle them, and Gu Tiancheng took the others to control the room and observe Gu Ling'er's movements.

How could Nika restrain them? In addition, with a few more wines, he forcibly broke into the control room, Gu Tian raised his eyes, saw the scene on the screen in front of him, and immediately recognized that this was the situation inside the Iron Wall Fortress.

"How did you do it" Gu Tianyang's wine woke up most of the time, staring at the screen incredulously, and his eyes couldn't take it off anymore.

The others also noticed it under Gu Tianyang's reminder, and they shouted one after another, and some stepped forward to try to poke those operation buttons, but were quickly stopped by Gu Tiancheng.

"I'm searching for confidential information about the Iron Wall Fortress, this is a highly confidential matter, since you bumped into it, you can always do it by closing your mouth and watching, right?"

The children of the Gu family are all people who have lived on the battlefield for a long time, and of course they know the stakes and stakes, so they stuck out their tongues and shrank their necks when they heard it.

Gu Tian didn't want them to see this, but since he had already broken in, he had no choice but to settle down.

The periphery of the Iron Wall Fort is heavily defended, and if it is replaced by the previous Gu Ling'er, I am afraid it will not be so easy to blend in. But now Gu Ling'er is different, he can easily control his own spiritual energy, and he can achieve the same frequency as the surrounding spiritual energy, no matter how powerful the spiritual energy scanner is, there is nothing he can do.

Although Gu Linger could also do this step before, she couldn't do synchronous frequency conversion. Psionic scanners are becoming more and more advanced, and there are fewer and fewer vulnerabilities that can be exploited. The inventor had known about the loophole of psionic frequencies for a long time.

In order to prevent insiders from using psionic loopholes to pass through the monitoring of psionic scanners, they have been continuously improved, adding conditions such as timed frequency conversion and irregular frequency conversion, even if they master the psionic scanner, they don't know what the frequency of the psionic scanner will be in the next moment, so they naturally plug the loophole.

But now Gu Ling'er can keep up with the frequency conversion of the psionic scanner in time, no matter how it changes, Gu Ling'er can adjust her psionic frequency to the same before the psionic scanner finds herself.

Of course, this is not only Gu Linger's own ability, but also with the help of Kerry's instantaneous calculation ability and instantaneous reaction ability. So that Gu Ling'er can react and adjust in tens of thousands of frames. Now the psionic scanner can do frequency conversion within a frame, this is not a battle of magnitude at all, Gu Ling'er can naturally deal with it easily.

It's a pity that the children of the Gu family didn't see how Gu Ling'er stole into the Iron Wall Fort, otherwise, they would have made even more fuss when they saw Gu Ling'er swaggering in.

Gu Ling'er had never been to the Iron Wall Fort, and at this time he was hidden in mid-air, a little confused, and he didn't know where to start.

However, his confusion didn't last long, and he thought of a good way to find out where those holy steps were as quickly as possible: scanning the strongest point of the active psionic energy unit must be where those holy steps are.

Gu Ling'er thought that she could do it, and immediately started the scanning operation. This action happened to be seen by Gu Tiancheng, and he almost jumped up.

"With such a blatant scan, aren't you afraid of being discovered?" Gu Tiancheng hurriedly reminded Gu Ling'er, but it was too late.

Gu Tiancheng's worries are very reasonable, Gu Tiancheng's spiritual energy scanning is an ability that he only has after practicing Allen's exercises, and he has never been discovered by others since he learned it.

But Gu Tiancheng is very self-aware, and that is because he has not yet encountered the real test. The current Iron Wall Fort is a real test for me.

The Allen Exercises come from Allen, from the Ancient Era, and those artifacts from the Ancient Era are likely to have the function of guarding against this kind of scanning. If it happens, Gu Ling'er will be exposed immediately.

It's a pity that Gu Tiancheng couldn't receive these ideas as soon as Gu Ling'er received them. Although Gu Tiancheng took advantage of Gu Ling'er's weakest time to sign a soul contract with him and formed a pet relationship.

But Gu Ling'er is still different from Cai Ling'er. Gu Tiancheng and Cai Ling'er can communicate ideas instantaneously without restrictions, and Gu Tiancheng is dominant, Gu Tiancheng doesn't want Cai Ling'er to know the thoughts, Cai Ling'er can't receive them, but Cai Ling'er's thoughts, Gu Tiancheng has the right to choose to know and not know.

Of course, Gu Tiancheng chose to refuse most of the time, after all, he had no preference for snooping on other people's privacy. But when needed, there was no obstacle to Gu Tiancheng and Cai Ling'er's communication.

But Gu Ling'er is different, Gu Ling'er is just a psychic spirit yuan stone, without a soul, so the soul contract's constraints on Gu Ling'er are very weak, if Gu Ling'er leaves Gu Tiancheng with an iron heart, Gu Tiancheng has no binding force on him.

But Gu Ling'er's further cultivation will definitely slowly form his own thoughts and consciousness, due to the existence of the soul contract, it is equivalent to giving him a preconceived formation of a deep-rooted concept: Gu Tiancheng is his master, and he cannot go against Gu Tiancheng's will.

Therefore, I don't worry that Gu Ling'er will leave Gu Tiancheng, but the connection between Gu Tiancheng and Gu Ling'er is not as convenient as with Cai Ling'er. It's okay at the beginning, Gu Tiancheng can take the lead and communicate with Gu Linger at any time.

But with the improvement of Gu Linger's self-awareness, Gu Tiancheng and Gu Linger became more and more equal in communication. Gu Tiancheng can cut off the connection between the two sides, and Gu Ling'er can too!

Now, Gu Ling'er has unilaterally cut off the contact between the two sides, what Gu Ling'er is thinking, Gu Tiancheng can only guess, and what Gu Tiancheng thinks, Gu Ling'er naturally can't accept it.

Of course, Gu Tiancheng could use his spiritual power to forcibly get in touch with Gu Ling'er. But Gu Ling'er was in the Iron Wall Fort, and when her spiritual power passed through the defenses, it was easy to be exposed.

Therefore, Gu Tiancheng didn't dare to act rashly, so he could only pray that Gu Ling'er would not poke a big mess inside.

Gu Ling'er scanned for a while, then locked on a certain direction, shook his body, and galloped away.

Somewhere in the depths of the Iron Wall Fortress, a white-haired old man opened his eyes from meditation, and in front of him, a simple bronze mirror shimmered with a faint blue light.

The old man bowed slightly, and said to himself: "You have such skills, but the old man looks down on you." ”

With his left hand stretched out and gently stroked the mirror, Gu Ling'er's figure appeared on the mirror, and the old man smiled lightly, "Little guy, it's been a long time." ”

Gu Ling'er was a bold man and rampaged through the Iron Wall Fort, ignoring any obstacles and defense nets, and went straight to the core of the Iron Wall Fort: the Iron Curtain Core Fortress.

As soon as she entered, Gu Ling'er found that she had fallen into a trap, and seven or eight holy steps holding various magic weapons appeared at once, surrounding Gu Ling'er.
