Gu Tiancheng was taken aback by this idea, and then the more he thought about it, the more likely it became: the big man had too much advantage, as long as he was a normal person, he could see that it was a matter of time before the Iron Wall Fort was lost. It is impossible for Carter, for his part, not to prepare for the aftermath of the defeat.

Judging from this device, Carter obviously didn't want to leave Fort Iron to the Han, so that Fort Iron Wall would become a frontier fortress for the Han to attack Carter.

Now that it has been discovered, of course, Carter's plot cannot be allowed to succeed. Gu Tiancheng immediately began to expand the scope of his search, looking for the key trigger.

It wasn't difficult to find the initiators, and soon an underground palace was found nearby, and the initiators were hidden inside.

Gu Tiancheng easily opened the heavy door of the underground palace and walked in. The others originally wanted to keep people on guard outside, but they were denied by Gu Tiancheng: it was also unsafe inside, and they needed to be covered by a dragon beard. And there is only one dragon beard, and he can't take care of the two ends.

Their fears were also justified, once the door of the underground palace was closed, wouldn't they be sealed inside!

You have to take some risks, especially the act of opening the palace gates, but you can't just watch the Iron Wall Fortress, which has been fought for for more than ten years, be destroyed. Even if this move exposes his whereabouts, he can't take care of it.

The inside of the underground palace was empty, except for a hill-like oval metal object in the center. Gu Tiancheng waved his hand to signal the others not to come forward, walked over cautiously, dismantled the fuse and then removed the other wires one by one, and then arranged a weightlifting formation on it, easily put it away, and put it into the Imperial Qiankun Ding.

It's a big killer, and it's a great way to ambush opponents who are far stronger than you. Even if there is no need for this, it is a huge gain to dismantle it and extract the huge spiritual energy inside.

As soon as the giant bomb was put away, the surrounding alarms immediately went off, and the sound was piercing. In the dark, the red warning lights were particularly glaring.

"What should I do? This is a complete alarm for them!" "Ari Hill was a little flustered, this was a veritable death place on the battlefield, whether the exit was sealed or the gate was closed, it could cause them to close the door and fight the dogs, and the situation was very unfavorable to them.

"Let's get out of here, we can't stay here!" said Ari Hill, who ran out first. As a result, as soon as he took two steps, he saw the heavy gate slam shut!

"It's over, it's over. Ari Hill stumbled.

"Don't panic, just an underground palace, can you trap us?" Gavin Muki comforted Ari Hill.

Leng Fei shook his head and said: "The situation is not optimistic, I observed just now, there is a thick enough space confinement circle here, even if that big guy explodes, it may not be able to explode." With our ability, it is not enough to break through the spatial confinement here. Looks like we're stuck here. ”

"Huh, what should I do then?" Several women were a little flustered, and they all looked at Gu Tiancheng involuntarily.

Gu Tiancheng was also secretly complaining in his heart about his carelessness just now. He also discovered the heavy spatial confinement circle, but just now he had been thinking straight that it was a protective equipment set up to prevent the sudden explosion of the initiator and spread to other places.

But they didn't expect that one day, such a protective device would be able to become a powerful magic circle to imprison them!

At this time, Gu Tiancheng is the backbone, others can mess up, but he can't. Even if you don't have any good ideas, you must pretend to be casual to stabilize the morale of the army.

"Hahaha," Gu Tiancheng burst into laughter, "Since we dare to walk in with a big grin, we have the ability to go out with a big grin." Now let's go back to the Imperial Qiankun Ding and wait and see what happens. When we're sure there's nothing going on outside, we'll go out and get out of here. ”

"Do you have a way?" the crowd was surprised and delighted.

Gu Tiancheng knew that words alone were not enough, so he took out the Mayan Divine Bow and waved it, "With this, are you still afraid of beating the space barrier in front of you?"

"Oh, you have the Mayan Bow in your hand! No wonder you are so sure, you really have a back hand. Everyone calmed down and followed Gu Tiancheng back to Yuqiankun Ding, carefully observing the movements outside.

At this time, no detection means could see what was going on outside, and could only scan over and over again in the empty underground palace, in vain, but it could not be stopped.

Suddenly, there was a buzz of business outside, a sound that you are all too familiar with, that is, through psionic transmission, the sound from the outside was transmitted inside.

Gu Tiancheng forced himself to be calm, but his heart had already begun to stir waves: Gu Tiancheng knew exactly how thick the space barrier was. With such a thick space barrier, it is still possible to transmit sound in, unless there is a preset sound transmission device in advance, if you rely on hard power, you won't believe it.

However, if it had been preset in advance, what was the purpose of the preset sound transmission device? Wasn't the purpose of installing such a thick space barrier to prevent misoperation from leveling the Iron Wall Fortress? In this case, the sound transmission device was purely redundant.

Gu Tiancheng began to break out in a cold sweat: Could it be that when this place was first built, it was considered that if someone broke in, it would use the space barrier to trap it inside?

That he was really unlucky, and he chose to throw himself into the net at this time.

"Hahaha, how does it feel to be trapped? The voice changed through the long microphone device, and it was very uncomfortable to listen to, but everyone could hear it full of schadenfreude and ridicule.

At this time, of course, Gu Tiancheng had to stand up and have a dialogue with the outside.

Gu Tiancheng also took the lead, and walked out of the Imperial Qiankun Ding, "Who is Your Excellency, please report your name." ”

"It doesn't matter who I am, the important thing is that you are going to die here, and there will be no more Gu Tiancheng in the rivers and lakes from now on! ”

Gu Tiancheng was shocked in his heart: the other party even knew who he was, and it seemed that he had already mastered his whereabouts. It didn't appear before, it was just luring the enemy deeper.

I don't care about thinking about where there is a flaw in my actions, and it is important to deal with the crisis at hand.

"Now that you know it's me, I want to know a little bit about me. Do you think I'm a reckless person? Since I dare to come in, I have full confidence that I will be able to get out! This foot-thick space barrier will not become an obstacle for me. Gu Tiancheng said deliberately carelessly.

The man was obviously not an ordinary person, and he praised him a few times and said, "I'll just wait outside to see how you get out." There wasn't much time, just fifteen minutes. Fifteen minutes later, the self-detonation device of this dungeon will be activated, and at that time, these people outside us will have to evacuate to save their lives, and you can only disappear forever with the destruction of this dungeon and the disappearance of this iron fortress. ”
