It wasn't until late at night that an elderly array mage mustered up the courage to come to Mu Qingying's side, hugged his fists and said: "Commander Mu, my subordinates believe that opening this mechanism requires a specific invocation, according to the old man's guess, this invoking thing is very likely to be a specific royal bloodline, and only the descendants can open this door." ”

As soon as his words fell, the other array mages stopped what they were doing, looked at Mu Qingying, and waited quietly for her answer, obviously, they all agreed with the old man's statement.

"I guess the bloodline alone is not enough, it should be accompanied by spells or other keys. Mu Qingying sighed lightly, didn't blame the formation mage's incompetence, but said calmly.

"Hey, Commander Mu, if that's the case, wouldn't Han Bing have the blood of the Luo Ying royal family? I'm afraid it's unlikely. The adjutant wondered.

"Since it is to divert the tiger from the mountain, then, there must be someone else who opened the mechanism, and Han Bing's role is just to lure our large army away. Mu Qingying said.

After listening to Mu Qingying's words, everyone thought for a moment and nodded one after another.

"What should I do next? The adjutant said.

"Smash it open, now that I've found the entrance, I don't believe I can't get in. Order, break the city formation, and blast the hole open for me. Mu Qingying said loudly.

"Yes!" the adjutant looked shocked. The city-breaking array is a city-breaking attack formation unique to the alliance, although the defensive ability is weak, but the attack ability is extremely strong, especially against such fixed targets.

Around the organ, the crowd immediately dispersed, and under the command of the adjutant and elders, a large empty space was soon vacated, and a huge siege formation was being formed 30 zhang away from the organ.

On the second floor of the dungeon, Han Bing's figure moved rapidly, and his hands quickly punched out one seal after another, falling on the forehead of each dungeon guard, and with his movements, a venerable dungeon guardian disappeared into the vast land, all of which were included in his ring.

In the corner, Su Tong had already removed the protective shield, and the three of them looked at Han Bing in amazement, it was really amazing to subdue these dungeon guards in such a short period of time.

"I was surprised that you had succeeded. The silver moon bow flashed, revealing Luo Yingzi's figure.

Han Bing gathered all the guards, his figure floated in the air, he smiled indifferently, and was about to speak, when suddenly there was a muffled sound from the upper floor of the dungeon, and with the muffled thought, the entire dungeon seemed to tremble.

"What's going on?" Su Tong stepped out of the corner, came to Han Bing, and looked around nervously.

Han Bing was also puzzled, he spread his consciousness and swept in the direction where the voice came from, but under the investigation, everything fell silent, as if nothing had happened just now.

About 20 breaths later, just as a few people were about to give up the investigation, there was a muffled sound from the upper floor of the underground palace again, exactly the same as last time.

"Someone is forcibly attacking the entrance. Luo Yingzi said coldly.

"Huh, how did they find the entrance?" Su Tong was startled, she didn't have to guess, she also knew who the attacker was.

"When we came in, we tried to cover up the traces as much as possible, but if we looked closely, we could still find some clues. Cui Feng's face changed several times, and he sighed helplessly.

"Judging from the movement just now, they have already made up their minds to come in. I'm just afraid, with this kind of attack intensity, no matter how strong the cave entrance mechanism is, it won't last long, right?" Han Bing's gaze turned to Luo Yingzi.

"Don't worry, they won't be able to come in for the time being. Luo Yingzi said casually.

"According to your estimates, how long can the agency last?" Han Bing asked. Everyone's eyes have gathered on Luo Yingzi at this moment.

"I think it can last at least two days. Luo Yingzi thought for a moment and said.

"Two days ......" Han Bing sighed lightly, he knew in his heart that with Mu Qingying's pampered personality, he would definitely be annoyed and angry after knowing that he was being teased by himself, once they attacked, then a big battle was inevitable, and if it was a head-to-head confrontation, the Xiuzhen Alliance would still have an absolute advantage.

"Even if they break through the entrance to the dungeon, it will be difficult to find the entrance to the second floor, let alone the entrance to each of the back floors, so we still have enough time. Luo Yingzi's words undoubtedly gave everyone confidence.

After listening to her words, everyone's faces really looked much better.

"In that case, let's hurry up to the third floor below, right?" Su Tong said.

Luo Yingzi nodded, and in a flash, she fell at the end of the original dungeon guard, and her hands shot out in the air, leaning less, and on the originally empty ground, a fluorescent gate slowly emerged, like a relief. There is also a singular symbol on the door.

"Without my spell, you can't open this door to the third floor. Luo Yingzi said, silently reciting some complex and incomprehensible notes in her mouth, and at the same time stretched out her right index finger to draw a symbol in the air, which was no different from the door. The symbol was formed, and under the finger of her jade hand, it fell into the door, coinciding with the symbol on the door, and after a crisp click, one of the doors began to slowly shrink towards the other, revealing a crack in the door of the underground palace.

"It's really mysterious. Han Bing appreciated, and now, his confidence is even stronger.

With the opening of the third door, from under the doorway, a burst of spiritual power that was so rich that it could not be dissolved gushed out, which made Han Bing and the others who came forward refreshed.

"With such three layers, what is the collection inside?" Han Bing couldn't help but ask.

"It's the spirit stone, and the Yuan Essence, which is the inventory of my Luoying royal family. Luo Yingzi's tone was complicated. The voice is also much lower. "Now, it should only be considered a relic. ”

After listening to Luo Yingzi's words, the three of them could not hide the shock and expectation in their hearts, the inventory of the imperial family, wouldn't that be an astonishing number? For cultivators, nothing is more important than spirit stones and yuan essence things. In addition to the surprise, he ignored Luo Yingzi's feelings.

Cui Feng couldn't wait, and after most of the door opened, he took the lead in stepping out.

"Wait-" Luo Yingzi was about to remind, when she heard Cui Feng screaming and catapulting out of the door, and behind him, dense sharp arrows roared out.

Han Bing reacted very quickly, and with a wave of his right hand, an ice wall appeared at the right time, blocking the entrance of the cave in time, and after a piercing clanging sound, the ice shattered, but fortunately, there was no danger to block this wave of attacks.

"Wait a minute, make you anxious. Luo Yingzi glared at Cui Feng angrily, "These arrows are all made of stainless steel, and they contain highly poisonous, which is to prevent intruders." ”

"Thanks to the big brother for saving me. Cui Feng smiled embarrassedly, for the rest of his life, he was afraid at this time.

"Be sure to pay attention next time. Han Bing didn't blame him, but glanced at Luo Yingzi with some embarrassment, and he realized that his group was obviously blatantly preparing to plunder the royal relics, and these relics, if there was an owner, it would be Luo Yingzi in front of him.
