Seeing that Qin Feng and Ning Yao were healing themselves, Yao Yue and Xing'er understood and silently stepped aside, paying close attention to their surroundings and taking on the important task of vigilance.

Although this place is deserted and desolate, it is still within the city of Wushuang.

If Bingpo were to investigate, he could easily detect their presence. Moreover, people occasionally pass through this area.

Qin Feng and Ning Yao were both seriously injured. After three days and nights of careful recuperation, their injuries began to improve and they gradually recovered to about 70-80% of their original condition.

Qin Feng did not intend to continue healing and stopped.

Although he has not fully recovered, he is no longer in serious condition and there is really no need for him to stay here and waste his time.

As soon as Qin Feng got up, Ning Yao followed closely behind, immediately stopping her healing and standing up as well.

Upon seeing this, Yaoyue and Xing'er immediately hurried over.

Qin Feng gazed at Yao Yue and Xing'er, a slight smile playing on his lips: "Why did you two come back?"

Yao Yue and Xing'er exchanged a glance and replied in unison, "Once a master, always a master!"

Qin Feng couldn't help but show a look of astonishment as he scrutinized Yao Yue and Xing'er before him. "Do you know what risks you will face if you follow me? A slight mistake could endanger your lives."

"We know!" Yao Yue and Xing'er answered in unison, nodding emphatically to show that they understood Qin Feng's meaning.

Then, the two said in unison, "Master, please rest assured, never doubt our loyalty to you. Even if you order us to our deaths, we will not hesitate for a moment!"

Qin Feng narrowed his eyes slightly as he listened to the two women's firm and sincere words.

Although he knew in his heart that the two women's loyalty to him might not be without ulterior motives, he felt no disgust whatsoever. Perhaps all they wanted was an opportunity to help him break through in his cultivation.

However, Qin Feng didn't say much. He simply looked around silently, then said softly, "Let's go." Before he finished speaking, he had already vanished without a trace.

Seeing this, Ning Yao's eyes revealed obvious hostility. After glaring fiercely at Yao Yue and Xing'er, she immediately used her movement technique and sped off in the direction Qin Feng had left.

At this moment, Yaoyue and Xing'er exchanged a glance, their eyes sparkling with undisguised joy.

They clearly sensed that Qin Feng had completely accepted them. This recognition filled them with joy and also filled them with anticipation for the journey ahead.

...

Time flies, and more than half a month has passed in the blink of an eye.

Qin Feng, Ning Yao, Yao Yue, and Xing'er finally arrived at the airspace near Shura City.

The airspace ahead is a forbidden area designated by the Asura Clan. Any outsiders who dare to enter will be killed without mercy.

Qin Feng did not choose to force his way in. After all, the Asura Clan had already secretly colluded with the Demon Lord Bingpo. If he was not careful, he might fall into an abyss of no return.

No one can be certain whether Ice Soul helped the Asura Clan create more Ancient Emperor Realm experts.

Even if these created ancient emperor-level individuals have limited strength, if their numbers are large enough, they can still make Qin Feng feel quite troubled.

With this in mind, Qin Feng decided to first lead Ning Yao and the other two women to land in the forest below before making any further plans.

Once his feet were firmly planted on the ground, his gaze began to flicker as he looked at Yaoyue and Xing'er.

Time ticked by, and as he noticed the increasingly unnatural expressions appearing on the two women's faces, Qin Feng finally spoke slowly: "I intend to help you break through your cultivation levels!"

Upon hearing this, Yaoyue and Xing'er were first taken aback, then their faces lit up with unbelievable joy. "Master! Is this true?" they asked in unison, their voices full of anticipation.

However, Qin Feng did not respond to their questions.

With a flick of his arm, he instantly produced two jade bottles from his robes and handed one to Yao Yue and the other to Xing'er. Each bottle contained three top-grade pills emitting a rich medicinal aroma—Spirit Source Pills.

"This is a Spirit Source Pill!" Qin Feng's gaze fell on Yao Yue.

"You're already at the peak of the Heavenly Emperor Realm, I don't know if this Spirit Source Pill will even work for you?"

"Give it a try!" "It would be great if you could break through, but don't be discouraged if you can't. I have other ways to help you!"

Yao Yue took a deep breath, calmed herself down, and nodded. "I understand, thank you for the medicine, Master!"

Qin Feng smiled slightly and turned his gaze to Xing'er. "Whether you can break through depends on luck!"

"Don't panic if you can't break through, I still have a way to help you!"

Xing'er, her face full of gratitude, knelt on one knee and said, "Thank you, Master, for the medicine. Xing'er will certainly not let you down!"

"You can try to break through here. Ning Yao and I will protect you!" Qin Feng didn't say anything more. He took Ning Yao's hand and walked towards a big tree not far away.

Yao Yue and Xing'er exchanged a glance, each took out a Spirit Source Pill and swallowed it, then sat cross-legged on the spot and began to refine it.

Time flies by, and a few hours pass in the blink of an eye.

During this period, Xing'er demonstrated amazing talent and perseverance, refining three invaluable Spirit Source Pills in succession.

As each pill was absorbed and fused, the spiritual power within her body surged like a mighty torrent, eventually breaking through the bottleneck and stepping into the remarkable realm of the Heavenly Emperor.

However, it is worth mentioning that, due to the special surrounding environment, the kind of earth-shattering celestial phenomena that people had expected did not occur.

This was something Qin Feng had anticipated, since his decision to let Xing'er and Yao Yue break through here was naturally a well-thought-out one.

For the next hour or so, Yao Yue, who had been completely silent, finally had her moment of glory—successfully breaking through to a higher cultivation level!

Thus, Yao Yue became the second powerful Ancient Emperor Realm being in the Heavenly Realm after Ning Yao.

This breakthrough, like Xing'er's previous breakthrough, was calm and uneventful, without any dramatic or spectacular events.

Witnessing Yao Yue's successful breakthrough, Qin Feng's joy was palpable.

He originally intended to give it a try, but he never expected that the Spirit Source Pill would have such a significant effect on advancing from the Heavenly Emperor Realm to the Ancient Emperor Realm.

This unexpected discovery was undoubtedly a huge surprise for him.

This means that in the future, he may be able to achieve the grand goal of mass-producing Ancient Emperor Realm experts through the miraculous pill, the Spirit Source Pill.

At that time, he will have enough strength to contend with the Demon Lord Ice Soul! He will no longer be as helpless as he is now every time he faces Ice Soul.
