Gu Tiancheng knew that he might be cheating himself, but he couldn't help but follow. If the other party really thinks that destroying themselves is more important than the well-preserved Iron Wall Fortress, they will definitely not hesitate to do so.

And Gu Tiancheng himself, but it is impossible to gamble on the lives of himself and the people around him that the other party will not do that.

"Hmph," Gu Tiancheng said strongly, "Since you don't want the Iron Wall Fort yourself, then it's no wonder to me." Let's start destructing now, I can't wait. ”

After speaking, Gu Tiancheng turned around and returned to Yuqiankun Ding. As soon as I entered, I was surrounded by a group of people.

"What you just said, is it true or false?"

Gu Tiancheng wasn't sure, "I don't know, but we definitely can't take it lightly, can we? Where did the self-detonation device come from? If there were, we would have discovered it a long time ago." Feel relieved. ”

"However, why don't you just use the Mayan Divine Bow to open the gap and go out?" Ari Hill looked at Gu Tiancheng suspiciously, "The Iron Wall Fort is imperative for us big men, and we definitely don't want to get just a bunch of ruins." Let them blow up the Iron Fortress, and it will be us who will lose. You don't understand that, do you?"

As soon as Ari Hill said this, everyone else also looked at Gu Tiancheng and asked Gu Tiancheng for an explanation.

Gu Tiancheng was helpless, so he had to take out the Mayan Divine Bow, and said in his mouth: "As a last resort, I really don't want to use the Mayan Divine Bow." The Mayan bow was the last resort to save one's life, and there was only one arrow a day! Once fired, it would have to be twelve hours before it could be generated. I'm afraid that there is a strong enemy outside, and we won't be able to deal with it when we go out, and we don't have the back hand of the Mayan Divine Bow, so we will fall into passivity. ”

Ari Hill hurriedly said: "That's also strong here." Go out with you and Leng Fei, who can beat you? Even if the other party has the assistance of an artifact, we also have it, don't we? At least this Imperial Qiankun Ding, I have studied it, and it is comparable to an artifact. I heard that you have another artifact in your hand, what are you afraid of them doing?"

Gu Tiancheng held the Mayan Divine Bow, "You have said so, then you can only try the power of this Mayan Divine Bow as you wish." To be honest, although I have already obtained the Mayan Divine Bow, it is really the first time that I have actually shot a Mayan arrow. ”

As soon as the words fell, Sima Xin added: "No, it's the second time, in the dungeon of the Mercenary Guild, you used it once." ”

Gu Tiancheng hurriedly nodded to show that he knew his mistake and stopped talking.

It is certainly theoretically feasible to use Mayan arrows to break the space barrier, but Gu Tiancheng does not know what kind of consequences such a thick space barrier will be caused if it is broken. If you can't, Gu Tiancheng doesn't want to use such a violent method to get out of trouble.

Of course, there is a clever way, which is to use the blue dagger to carve a hole in the space barrier little by little. The annihilation attribute of Tianyi Dust Water can ensure that the hole carved out will not be closed immediately, enough for them to escape.

But the outside says that there is a detonating device inside, whether it's true or not, you can't really joke with your life. Moreover, there are still people outside, and if you open a hole to go out, aren't you just being caught alive outside?

Therefore, it is imperative to use Mayan arrows to break the spatial barrier here.

Gu Tiancheng took out the only Mayan arrow, put it on the string, and suddenly his heart moved: use the method of a hundred folded arrows to shoot out, concentrate on one point, as long as you drill a hole, it will definitely not cause a big explosion like the collapse of space, and the iron wall fort outside will definitely be saved.

Although it was just his wishful thinking, Gu Tiancheng was very sure that this was the case. Even he himself wondered why he was suddenly so confident, so confident that he couldn't tolerate the second possibility.

Although he knew that the situation was different, Gu Tiancheng enjoyed this feeling that the world was in my hands, and even what would happen in the future could be completely in his own hands, wasn't he the master of this time and space?

Gu Tiancheng held the Mayan Divine Bow in his hand tightly, feeling the wonderful feeling between himself and the Mayan Divine Bow, as if he had a spiritual rhinocera.

Gu Tiancheng was even more convinced at this time that what Alan said when he left was right, from now on, there was only one master of the Mayan Divine Bow in heaven and earth! Because of this wonderful feeling, he had never felt it before. Even after Allen left, there was no such strong sense of interaction.

Gu Tiancheng was happy in his heart, and said softly: "Old friend, it's up to you next!"

An arrow was fired, and the Mayan arrow was surprisingly slow, almost moving in the direction of the original gate. Then, as if stopped by an invisible barrier, the Mayan arrow stopped there, and then it beat at a very fast rate, and with each beat, it went a little deeper.

"Well, Mayan arrows don't work either. Ari Hill sighed in disappointment.

Gu Tiancheng retorted: "You don't understand, this is the Mayan arrow deliberately reducing its power, to break the spatial blockade here little by little." Prevent a big explosion in space. ”

Although Gu Tiancheng was calm, he was actually shocked in his heart: although he hoped for such an effect, there was actually no change in the operation, and the standard method of 100 folds of arrows. But isn't it amazing that the Mayan arrows that were shot out were exactly what they wanted?

With such a little effort, the Mayan arrow had already drilled a small hole, jumped out with a swish, and then suddenly recovered the original appearance of the hundred-fold arrow, and began to kill all sides with joy outside.

It's a pity that there was no one outside, Gu Tiancheng took them out of the small hole, released his divine sense, and found that the entire military area had become empty!

Gu Tiancheng wondered: Could it be that what the man said was true, this underground palace really had a self-detonation device, why didn't he detect it?

Just thinking about it, there was a sudden low muffled sound inside the underground palace behind him, and dense cracks suddenly appeared in the thick space barrier, and it soon collapsed, and there was no big explosion that Gu Tiancheng was worried about, and the space barrier was destroyed very calmly.

The entire underground palace had collapsed into a pit hundreds of meters deep at this time! Such an explosion effect, if there was no thick layer of space barriers outside, not to mention the Iron Wall Fort, hundreds of miles around the Iron Wall Fort, I am afraid that it would have been razed to the ground!

Fortunately, Gu Tiancheng only drilled a small hole with the Mayan arrow, and did not destroy the integrity of the space barrier, otherwise, even if they could get out of the predicament smoothly, they would inevitably have to hang in the subsequent big explosion.

Gu Tiancheng knew that this was just the beginning, since the other party knew himself and knew his whereabouts, he would definitely come back to check the results.

Without saying a word, Gu Tiancheng and the others directly entered the Imperial Qiankun Ding and prepared for battle.

After Gu Tiancheng's repeated transformation, Yu Qiankun Ding has stepped up its efforts to develop into a battle fortress. With the addition of the Demon Gathering Banner and Tianyi Dust Water, the combat performance of the Imperial Qiankun Ding has been greatly enhanced, and it is no longer the magic weapon of pure defense and passive beating.
