Yu Roufei couldn't have imagined that Ling Xiao's aura would instantly explode at this time, and he had gone from the initial realm of a low-level sage to the realm of a mid-level saint.

She couldn't figure out what was going on.

You must know that the strength that needs to be accumulated after reaching the Sage is quite huge, and it is not easy to increase the strength, even if Tianbin is extremely good, it takes time to accumulate and gradually increase the strength.

Unless you take a pill or spirit grass that improves your strength, you can instantly increase your strength.

However, Ling Xiao had always been by her side, and she only saw a little green light disappear into his head, and then his strength exploded.

"What kind of strange thing is that spirit tree, which can actually increase Ling Xiao's strength, could it be that Ling Xiao relied on this method to reach the Sage Realm level in just a few dozen cultivations?" Yu Roufei guessed.

If Ling Xiao heard this, he would definitely immediately shout injustice!

Although he has the explosion of strength obtained by performing adventures, there are also a lot of strengths that have been cultivated through his own efforts, and his adventures have only been obtained after a situation of nine deaths and a lifetime, but there are not too many tricks.

Ling Xiao didn't have time to explain to her now.

He used the Exclusive Returning Yuan Gong to transform this energy into five attributes, absorbing and refining them one by one.

Ling Xiao cultivated all five attributes at the same time, and the advanced energy required was several times higher than that of ordinary martial artists.

With this huge energy from the Immortal Tree, it should have been enough for an ordinary Sage to advance to another level, but when Ling Xiao digested and absorbed this power, he had only reached the point of the Great Achievement of a low-level Sage, and there was still a lot of distance from the peak of a low-level Sage.

This was also the feedback that Ling Xiao received from the power of the Heavenly Fire Bead when he was in the fifth layer, and this energy was added to reach such a realm.

Ling Xiao was still a little dissatisfied with this, and shouted at the immortal tree to send more strength.

The Immortal Tree was so depressed, it had just entered the first order and became a ninth-level holy tree, and its extra power was already very large when it fed back to Ling Xiao, and it was not satisfied.

It simply chose to ignore it, soaking in Ling Xiao's spiritual liquid to continue to warm its body.

Its current body is more verdant and vigorous than before, crystal like ink, and it looks even more magical and extraordinary.

With its current ability, the efficacy of the floating sap of the 10,000-year-old tree, the fruit of the 10,000-year-old tree, and the immortal root has increased several times.

If Ling Xiao knew, he was afraid that he couldn't help but ask for and squeeze it.

"Haha, it seems that the opportunity to follow this kid is too great, but after thirty years, not only has the essence been restored, but it has also gone further, my old man has not looked away!" said the green man proudly in Ling Xiao's sea of knowledge.

The Immortal Tree returned, and Ling Xiao and Yu Roufei headed for the next layer again.

The space on the seventh floor is a metallic space, and the pressure of space distortion here almost makes the two of them breathless.

Fortunately, they have regained their ability to fly and do not need to walk anymore.

The biggest danger here is the spatial power of Jin Rui, which is like a sharp blade used by a high-level sage, constantly strangling them.

Here, Ling Xiao and Yu Roufei had no way to take advantage of it, so they could only rely on their excellent strength to break through.

Ling Xiao's body was comparable to a high-level holy weapon, and his defense was already quite amazing, but in the face of these golden sharp blades, he was still bombarded, and the golden blood on his body kept splashing, and even the dragon scales fell a lot.

Holding the golden dragon spear, he burst out with powerful combat power, endured all the pain with an indomitable will, and forged ahead bravely all the way.

Yu Roufei is a peak sage, but her physical body is not as strong as Ling Xiao, fortunately, she has a high-level defensive armor to protect the vital point, but she is inevitably injured, and the jade arms and round legs are all more scars that can be seen deep bones, which looks extremely hideous and terrifying.

After taking the healing pill many times, the two finally crossed the most dangerous area with difficulty.

Along the way, the two got this layer of harvest again.

Diamond, one of the precious materials necessary for refining metal artifacts, is a little more precious than the black ink stone found in the fourth layer.

After all, metallic materials are particularly difficult to find, and their hardness is better than that of black ink stone and 10,000-year-old dark stone...... and other materials are much more powerful.

In addition to harvesting diamonds, Ling Xiao also harvested a ball of metallic origin power "Golden Source Qi"!

This kind of golden source qi is no worse than the 10,000-year-old Earth Center Spring, and it is the purest source of power for metallic martial artists and spirit beasts.

For low-level martial artists or spirit beasts, if they directly absorb and refine this energy, their strength will definitely explode several times, and there will be no side effects. It can also improve the constitution of gold.

How tempting!

This made Ling Xiao smile from ear to ear.

If he directly refined this mass of Golden Source Qi, he would definitely be able to directly advance to the strength of a mid-level sage.

It's just that Ling Xiao didn't do this, this golden source qi is not much, he wants to give up some of it

The Golden Wolf King advanced, and part of it was reserved for his woman Cai Xiayue, his son Feng Lingtian, and his brother Ye Yunfeng.

After all, they must be metallic physiques, and this golden source qi can exert the most powerful effect on them.

Ling Xiao had the help of the three foreign bodies, and he was not afraid that he would not be able to advance at all, it was only a matter of time.

Besides, there are two floors in the back, and maybe there will be some amazing things that can help him advance.

But then again, he wondered if the Sages who had rushed to the Heavenly Domain from the Lingxuan Continent in the past would also have obtained all kinds of Holy Treasures like him?

Before the eighth layer of the spatial barrier, Ling Xiao had the help of the Ancient Emperor's divine skills, and the scars on his body had healed.

Although Yu Roufei is a peak sage, it is difficult to compare with Ling Xiao in terms of healing speed.

After taking a lot of pills, she gradually recovered.

"How is it okay?" Ling Xiao asked as she looked at Yu Roufei with some distress.

Yu Roufei said with a stubborn look: "You better take care of yourself first!"

How to say that her strength is above Ling Xiao, and in the face of various crises, she is not as calm as Ling Xiao to deal with, which really makes her depressed.

"Well, if you really can't do it, don't force it, maybe I'm not as good as you when it comes to combat power, but when it comes to life-saving means, you must not be able to compare to me, you don't need to deny this!" Ling Xiao said emphatically, after a pause, he said again, "I have a big effect on that group of golden source qi, and I can't divide it for you for the time being, let's see what holy things are behind me, and then let you take advantage of it more, do you think this is okay?"

Yu Roufei nodded, agreeing with Ling Xiao's words, and then she sighed, "It's dangerous all the way, and I don't know if my stepfather also broke through like this back then!"

Ling Xiao heard Yu Roufei talk about her stepfather, he had left the Sand Domain for the Heavenly Domain about six thousand years ago, when his stepfather was already a peak saint or even a half-saint emperor realm.

The time when he left was somewhat consistent with the time when Ling Xiao's master and evil master left.

However, the Evil Emperor is in the Central Domain, and Yu Roufei's father-in-law is in the Sand Domain, there should be no intersection, maybe it's just a coincidence!

"Don't worry, your father-in-law has been regarded as a god by you, and his life-saving methods are definitely no worse than ours, not even like us, and he directly broke through the nine levels and went straight to the Heavenly Domain!" Ling Xiao comforted her.

Yu Roufei chuckled and said sincerely, "Thank you!"

"Don't say that you meet like this, sooner or later you will be my woman, and your stepfather will also be my stepfather!" Ling smiled and smiled.

"Hehe, when your strength catches up with me, I'll give you your woman!" Yu Roufei smiled happily.

Through the contact these days, she already knows Ling Xiao's character very well, if Ling Xiao's strength can surpass her, she really doesn't mind surrendering to him and being willing to be his woman.

"Don't worry, you won't have to wait too long for this day!" Ling Xiao said quite confidently.

There was a hint of longing in his eyes, for a woman had said this to him before.

When his strength had caught up with her, he and her were separated, and now there was no news, and he felt extremely guilty.

"Mengqi, you wait, I'll find you soon!" Ling Xiao shouted in his heart.

Ling Xiao and Yu Roufei regained their strength and went towards the eighth layer again.

The spatial barrier of the eighth layer was very thick, and even Yu Roufei's strength could not be broken at once.

In the end, after many times of her all-out attacks, she broke a hole that could only be used by two people.

The two of them quickly swept in, and when they just entered, the space immediately healed, and the speed was so fast that if they were half a beat slower, they would have to reopen the space again.

When they entered the eighth dimension, they didn't sense anything wrong, but they found a strange phenomenon.

That is, there is a change of day and night in this space, and this change is quite fast, one moment it is daylight, and the other time it is night, flashing and flashing, as if the lights are on and off in the night, and they are resting and bright.

"Could it be the spatial power of light and darkness here?" Ling Xiao thought suspiciously.

Yu Roufei on the side didn't answer, but her brows furrowed, as if she had thought of something terrible.

"We must rush to the barrier of the ninth layer at full speed, the alternation of light and darkness here is extremely fast, it should have produced a great force against time, and our lives will be quickly exhausted due to the rapid passage of time!" Yu Roufei screamed in panic, directly grabbed Ling Xiao's hand and swept forward.

She got out of here as fast as she could in the first place.

Ling Xiao didn't feel anything after listening to her explanation, even if time passed faster, it would be nothing, it must be like they had reached the sage with a lifespan of more than 10,000 years, even if they lost hundreds of lifespans, it would be negligible.

It's just that just when he didn't think so, he found a Yan zhòng crisis that made him feel numb in his scalp.
