"Come in!" An old but majestic voice floated out, and everyone was shocked, especially Zhang Qiang and others, who began to get nervous one by one.

This was the second time they had met Zi Lao since they entered the Purple Peak Palace, and the first time was naturally when they entered the palace.

I thought that this generation could only nest in the East Courtyard, but I thought that there would be a chance to meet again.

Compared with them, Murong Su's face was relaxed and calm, as if he had entered his own yard, without the slightest nervousness.

The high-ranking Zi Lao was still wearing dark purple robes, and when he saw them coming in, he leaned back slightly, squinted his eyes, swept his gaze over everyone, the essence of his eyes flickered, and finally his gaze stayed on Murong Su.

"Do you know why I called you here?" Zi Lao looked at a few people and asked, his deep and deep voice spread in the silent hall, which was especially loud.

As if a heavy hammer had been smashed, Zhang Qiang and the others jumped in their hearts, and fine sweat was faintly coming out of their foreheads.

Murong Su sighed in her heart, but did not answer, at this time, it was not suitable for her to speak.

"Back to Zi Lao, we don't know, please Mingjian!" Su Mo took a step forward and said respectfully.

Even if he knew it in his heart, he chose to pretend not to know at this time.

"Heh, you boys, you're going to fool the old guys." Zi Lao sighed lightly, and instantly broke the tense atmosphere in the hall, because of his light laughter, the whole atmosphere was different.

Everyone's hearts were relieved, and they were inexplicably relieved.

"You have just advanced, and you have made such a big noise, but it is difficult to get old and not pay attention, tell me, what's going on?" As he spoke, Old Zi habitually tapped one hand on the table, his eyes narrowed, and his silver-gray pupils flashed a dark color.

Everyone's nerves tensed again, knowing that they couldn't fool around anymore.

Seeing the situation, Murong Su took a step forward and successfully attracted Zi Lao's attention.

In fact, from the time she came in until now, Zi Lao's attention has always been on her.

If it is said that the collective advancement of everyone has nothing to do with her this time, Zi Lao will not believe it.

"Back to Elder Zi, the disciple inadvertently poured out a medicinal liquid, originally I just wanted to try it for your senior brothers, but I didn't expect such an accident to happen today!" Murong Su lowered his head, his voice crisp and pleasant.

"Oh, what potion?" Zi Lao's eyes lit up obviously, and his body sat up straight instantly, even if he suspected that this change was related to Murong Su, he didn't expect to answer like this.

According to Murong Su's words, this kind of medicinal liquid can improve people's strength, and the effect is absolutely obvious, just look at these people in the Eastern Courtyard.

If you get this kind of thing and give it to all the children of the Purple Peak Palace, then the overall strength of the Purple Peak Palace can be imagined.

"Hui Zi Lao, this medicinal liquid, because it has the effect of washing tendons and refining the marrow, so the disciple temporarily named it the marrow washing liquid, but the effect is not very stable, this time several senior brothers can all advance, it is really unexpected."

Murong Su replied without humility or arrogance, fooling people unequivocally.

Anyway, only she knows about the entire Earth Boundary Continent about this marrow washing liquid and calcining liquid, and if she doesn't say it, who can see through it?

"Washing the muscles and refining the marrow?" Zi Lao's heart trembled, his eyes became more and more scorching, and the gaze that looked at Murong Su was eager to melt it on the spot.

"Did you really make this kind of thing? If there is anything else, please submit it and take a look! Zi Lao forcibly suppressed the excitement in his heart and looked at Murong Xu and said.

This palace master, if he is really a god, casually sent such a treasure to the Ziding Palace.
