Tang Wuji was stunned when he heard this, and quickly stopped, turning his head and looking at his daughter with some curiosity.

He couldn't imagine any way his daughter could open the door.

Tang Mingyu untied his belt at this time, which was the Jiufeng Chaoyang Knife.

Tang Wuji had already seen his daughter's soft knife, which could be called a miracle in the world, during this time.

Now seeing his daughter come down with a knife, he couldn't help but ask curiously, "Xiaoyu, are you going to use the Jiufeng Chaoyang Knife to split this door?" ”

Tang Mingyu shook his head and said, "Father-in-law, no, because I suddenly thought that this knife is related to the Nine Phoenix Empress just now, and the thickness and width of this knife are close to this keyhole, maybe it is the key to open this door." ”

Tang Wuji was a little unbelievable about such a whimsical thing, and he immediately said, "You can try, but you must be careful not to trigger the mechanism here." ”

Tang Wuji's worry was right, although Tang Mingyu considered this possibility, but if it wasn't, then it would definitely touch the mechanism, so she hurriedly replied: "Father-in-law, don't worry, I'm wearing the Nine Phoenix Treasure Clothes, and the mechanism can't bear me." But you, don't get too close. ”

Tang Wuji shook his head and said with a smile: "Although my father doesn't have a treasure robe, it's not much different from King Kong's incorruptible body, and I believe that the authorities can't help me, so you can try it with confidence, and give you a back for your father." ”

"Well, I'm going to start trying." Tang Mingyu nodded, immediately approached the door, and slowly stuffed the knife from the tip of the knife into the keyhole.

Not to mention, when the knife didn't go in, it was really very appropriate, which made Tang Mingyu feel that what she was thinking should be right.

However, the imaginary opening of the portal did not appear, and neither did the mechanism.

What's going on?

Tang Wuji said: "Xiaoyu, if it doesn't work, forget it, let's go back and think about it in the long run." ”

Tang Mingyu shook his head and said, "Father-in-law, I know what's going on. ”

When the Jiufeng Chaoyang Knife was inserted just now, Tang Mingyu did not use the Red Cloud True Qi, she thought that the original treasure box also needed the Red Cloud True Qi, maybe this time too.

After speaking, Tang Mingyu silently used the Nine Phoenix Devouring Heaven Recipe and poured the Red Cloud True Qi into the Nine Phoenix Chaoyang Knife.

In an instant, the entire knife emitted a red light, and there was red light leaking out of the gap and the knife interface, making Tang Wuji feel that this time there might really be hope.

However, after waiting for a while, the result disappointed both Tang Mingyu and Tang Wuji, especially Tang Mingyu, who would be stunned, isn't it? What steps are missing here?

Fortunately, Tang Mingyu is a persistent and good at thinking and analyzing, which is also a characteristic of studying archaeology, and disappointment did not make her give up, but fell into contemplation.

Such a huge portal, now underwater, under huge water pressure, so to open this door will definitely require a higher force, how can we greatly stimulate the machine inside to open this door?

Thinking of strength, Tang Mingyu naturally thought of the Nine Phoenix Sword Technique.

Thinking of the Jiufeng Sword Technique, and then looking at the height of one meter and three meters, and the gap between the two, Tang Mingyu quickly thought of the move of Yifeng's birth.

Could it be that it is necessary to use the trick of Yifeng's birth to pierce the gap in the door with great force, so that the powerful impact generated by the Red Cloud True Qi can rush through the machine inside the door and open this door?

Tang Mingyu felt that his analysis was reasonable.

When you think of it, you do it.

This is what makes Tang Mingyu different from many girls.

Pulling out the Jiufeng Chaoyang Knife, Tang Mingyu coiled back into his waist, Tang Wuji thought that Tang Mingyu had given up, but he didn't expect Tang Mingyu to be calm and said: "Father-in-law, don't worry, I have thought of a way again." ”

"Xiaoyu, don't be in a hurry for your father, you think slowly." Tang Wuji still admires his daughter very much, her daughter is open-minded and has a lot of ideas, more than he has as a middle-aged man.

At this time, Tang Mingyu had already put into action, and as soon as he pressed the switch on his waist, a move and a phoenix came into being, and the Nine Phoenix Chaoyang Knife in his hand quickly pulled out and turned into a red light at the same time, piercing into the gap very accurately and quickly.

Hearing a bang, the door seemed to burst, and then the water vibrate, and an incredible scene appeared on the door, nine phoenixes emitted red light, lifelike, as if swimming in the water.

At this time, Tang Mingyu felt a suction force inside the door, as if she was absorbing her Nine Phoenix Devouring Heaven Recipe True Qi.

Although she was worried, she didn't dare and couldn't retract her internal force at this time, and the red cloud true qi in her body poured into the door like a broken embankment.

Fortunately, Tang Mingyu not only had the Red Cloud True Qi in her body, but also the Shaoyang True Qi that was no less than the Red Cloud True Qi, which could support her Qi Holding Technique.

And inside the door seems to be able to judge independently, only absorbing the Red Cloud True Qi, but not the Shaoyang True Qi.

The Red Cloud True Qi contained in Tang Mingyu's body was very powerful, and at this time, it was continuously fed into the door, and when it arrived, not only the nine phoenixes on the door, but even the entire door emitted red light.

Just when the Red Cloud True Qi in Tang Mingyu's body was almost exhausted, she suddenly felt the underground shake for a while, and then the entire black city wall began to shake.

Tang Wuji was taken aback, "Xiao Yu, the mechanism may have been triggered, let's go quickly." ”

It's a pity that at this time, Tang Mingyu can't walk at all, her hand seems to be sucked on the handle of the knife, and she can't even let go, she will also feel a burst of fear, this black city wall will not collapse, if this is the case, I am afraid that she will become a traverser who is buried alive in a tragic way.

"Father-in-law, you go quickly, it's too late."

"Xiaoyu, if you don't leave for your father, I'll save you."

Tang Wuji was not the kind of person who was greedy for life and afraid of death, so he hurriedly came up and tried to pull Tang Mingyu away.

But at this moment, Tang Mingyu felt an energy like high-voltage electricity coming from the hilt of the knife, and this energy passed through her body and directly hit Tang Wuji's body.

Tang Wuji was struck by lightning and was suddenly shocked several meters away.

Fortunately, Tang Wuji's skills were profound, and although he was paralyzed by the blow, he dispelled this paralysis with a little luck, and asked in horror, "Xiaoyu, what's going on?" ”

Tang Mingyu didn't know what was going on, this power came from inside the door, she hurriedly shook her head and said, "Father-in-law, I don't know either, don't come near me yet, I don't think I'll be in danger for the time being, you stay away." ”

Tang Wuji chose to believe his daughter, he swam a little farther away, and then stopped silently to watch the changes in his daughter and Fengcheng.

The change continued, and the entire city wall shook violently at first, and after the vibration reached a certain level, only to hear another click from the ground, as if something had been opened.

Immediately afterward, Tang Mingyu saw that the black city wall that was sinking under the water actually began to have a force to rise upward.

What's going on here? Could it be that Fengcheng is going to resurface the Devil's Quicksand River?
