"clear!"

Li Yundong nodded, and without saying a word, he immediately asked Duan Yanran to pour out the materials for the formation from the Qiankun bag again.

Then, as the demon son's instructions, he assigned tasks to Duan Yuyan and others one by one. The four of them quickly became busy in the underground palace...

Especially Li Yundong, he was so busy that he was about to fly. On the one hand, he needed to guide Duan Yuyan and others to place different materials in the corresponding position as the demon was instructed, and on the other hand, he also had to repair some of the missing runes on the stone pillar!

Time is tight and the task is heavy!

Among them, Duan Yanran is fine, and she has some understanding of rune formation. She is basically clear, but Duan Xiaoxiao and Duan Xiangrui are different!

These two people had almost no foundation in runes and formations, and they could be said to know nothing. At this time, except for doing some of the most basic transportation work, almost all the rest had to be done by Li Yundong!

At the beginning, everything went smoothly!

Because according to the Demon Son, the formation here does not seem to have been destroyed by humans!

It was more like avalanches or earthquakes occurred outside, causing some extremely slight displacement of the array base. In addition, the existence of the large array was too long, so a trace of cracks appeared in the original flawless seal.

And no one should have discovered this crack yet, so as long as they can seize the time and repair the seal before everyone outside finds this crack, it should be no big problem!

While busy, Li Yundong also looked at the environment in the underground palace and found that there were a total of 108 pillars here, and there were about twenty pillars with displacement or missing runes!

It took Li Yundong nearly an hour to barely repair two of them!

In other words, it is likely that it will take him nearly nine hours to repair all the damaged twenty pillars.

However, practice makes perfect. With Li Yundong's continuous repetition, his attainments in runes and formations are also slowly improving. When he gradually becomes proficient, it may not take that long!

What surprised him even more was that Duan Yanran seemed to be very talented in this regard. After reading it a few simple times, when Li Yundong repaired the fifth pillar, she actually learned how to repair runes!

Although the speed was very slow, when Li Yundong repaired the tenth pillar, she actually repaired the runes on another pillar independently!

"Very good!"

Li Yundong was overjoyed and couldn't help but praise him: "I didn't expect that your talent in rune formation is so high. After just reading it a few times, I actually learned it!"

"If there is a famous teacher's guidance, the future achievements will be limitless!"

"Yeah?"

Duan Yanran smiled and shook her head: "Compared with you, I'm still far behind!"

"But when you have the chance in the future, you can teach me. I am really interested in this aspect!"

"OK!"

Li Yundong smiled and said, "Then let's talk about it later!"

"The top priority is that we have to repair the formation and seal here before someone outside discovers this crack!"

"Um!"

Duan Yanran nodded, and immediately stopped talking, but continued to find another pillar to repair it.

After about four hours of this, the two of them quickly repaired the eighteen pillars, three of which were completed independently by Duan Yanran. With the last two pillars, they were about to complete it!

"call--"

It was not until this time that Li Yundong breathed a sigh of relief. He was about to seize the time and quickly repair the last two pillars and completely block the crack!

But at this moment, an accident happened suddenly...

Almost just when Li Yundong and Duan Yanran walked to the last two pillars, they had not yet waited for them to repair them!

At this moment, in the entrance of another passage not far from them, a loud "boom" sounded suddenly, and a strong cold wind blew in from the hole in an instant!

At the same time, a large amount of blood light also gushed out with the cold wind!

In a vaguely, Li Yundong saw a sharp cold light, and with a "swoosh", he rushed towards Duan Yanran next to him and slashed over!

"careful!"

Li Yundong was startled. With Duan Yanran's strength, she could have avoided it in advance!

However, she had now begun to repair the runes on the stone pillar, and she was immersed in the runes all her mind. At this moment, she had no intention of avoiding them?

Li Yundong was helpless, and at this time he didn't even bother to continue repairing the runes on the pillar. He instinctively threw Xuan Yanran next to him to the ground!

I beat several times on the spot and barely avoided the sharp cold light!

Then there was a loud bang!

Looking at the place where Duan Yanran was just now, there was a big pit that was more than three meters long at this moment!

"elder sister!"

At the same time, Duan Xiaoxiao and Duan Xiangrui, not far away, finally reacted and hurriedly ran over, saying in a shocked look: "It's so dangerous!"

"If Brother Li hadn't reacted quickly enough and threw his sister to the ground in time, the consequences would be unimaginable!"

After saying that, they realized that whether it was Li Yundong or their sister Duan Yanran, their faces were extremely hard to see!

Especially Li Yundong, his heart was even more chilled and he subconsciously muttered: "It's over!"

"ah?"

Duan Xiangrui was stunned for a moment and asked hurriedly: "What's wrong?"

"Stone pillar!"

Duan Yanran gritted her teeth and said, "The stone pillar was destroyed!"

"What?"

Duan Xiangrui's face changed drastically. When he hurriedly looked back, he found that the stone pillar his sister was repairing had been split in half by the sword energy just now, and one of them had even fallen into the pit that was split out by the sword energy...

"this……"

Duan Xiangrui was stunned at the time. At the same time, Duan Yanran on the ground quickly got up and asked Li Yundong quickly: "What should I do?"

"I……"

Li Yundong was speechless because he didn't know what to do. He was stunned for a moment. He was about to throw this problem to the demon in his body to see if he had any way to save it!

However, before he could speak, the demon in his body spoke first, and said anxiously: "Someone is here!"

"quick!"

"Take them to hide first!"

"What?"

Li Yundong's face changed drastically, and he dared not hesitate at all. He hurriedly took Duan Yanran and others back more than ten meters away, hiding directly behind a stone pillar on the edge!

"What's wrong?"

Perhaps seeing something wrong on Li Yundong's face, Duan Yanran asked, "What's wrong?"

"Don't talk!"

Li Yundong hurriedly made a gesture to silence them: "Someone is here!"

"ah?"

After hearing what he said, Duan Yanran and others' faces changed. Before they could even wait for them to react, they could surely hear a mess of footsteps sounded from another hole not far away...

Immediately afterwards, seven or eight people walked in carefully through the entrance of the passage. Li Yundong narrowed his eyes and looked at it carefully, and his face changed drastically!

Because the person in the leader is not someone else, it is Bai Qizhi, who had met once in Yucheng before!
Chapter completed!
