Yuhua's mind was pulled back by Yuning's exclamation, she followed Yuning's line of sight, and also saw the green fluorescence emanating from Yunfei and Xiaozi's bodies.

"What's going on?" Yu Ning looked at Yunfei and Xiao Zi, and then at the green key in his hand, and lost his mind for a while.

"Are these two people ...... Is it the key to entering the Heavenly Spirit Tree Realm?" this incredible thought flashed through Yuhua's mind, and her gaze at Yun Fei and Xiao Zi suddenly became weird.

Yun Fei and Xiao Zi were also confused by the second monk, and they didn't know what was going on.

"I thought it was because of the life in the body, but now it seems that it has nothing to do with the life at all. All kinds of conjectures flashed in Yun Fei's mind.

The old ghost reminded at the right time: "Little master, it seems that only by finding the common ground between you and Xiao Zi can we explain the current situation." ”

"What do I have in common with Xiao Zi, what do I have in common with Xiao Zi...... And it's something that the old ghost doesn't know!" Yun Fei had a flash of inspiration in his mind!

I still remember that when Yun Fei was in the heaven and earth below, he was chased and killed by the Yin Yang Sect and other forces in Winterfell, forcing him to abolish his own meridians, Xiao Zi in order to save Yun Fei, he also forcibly fled regardless of the loss of meridians, and later he made a big fuss in the Yan Dynasty because of Xiao Zi, so that the Yan Dynasty royal family took out their treasures, and it was through that treasure that Yun Fei and Xiao Zi were able to continue the meridians and reshape the dantian!

To this day, Yun Fei still doesn't know what that gray substance is, and it can actually allow him and Xiao Zi to re-cultivate, even the experienced old ghosts!

"If you want to say that I have something in common with Xiao Zi, the only thing that is the mysterious substance that helped us reshape the meridian dantian. Yunfei was determined.

The old ghost said: "It should be that thing." Now it seems that the little master and Xiao Zi actually got the key to enter the Heavenly Spirit Tree Realm by accident. ”

Indeed, judging from the current situation, Yunfei and Xiao Zi didn't need the key provided by Yuhua at all, and they could enter this Heavenly Spirit Tree Realm by their own chances.

"That ......" Yuhua on the side asked tentatively, "Lord Yunfei, what are you ......?"

Yun Fei shook his head and said, "We don't know, but looking at the way it is now, it seems that Xiao Zi and I also have the qualifications to enter this Heavenly Spirit Tree Realm, right?"

"That's right, that's right. Yuhua nodded affirmatively, then she paused and said straight to the point: "Two adults, since you can enter the Heavenly Spirit Tree Realm without that key, please return that key to Yuhua, and Yuhua will prepare a reward to compensate the two adults." ”

"What?" Xiao Zi said angrily, "and you want to pay off your debts again?"

"Xiao Zi!" Yun Fei scolded Xiao Zi, he thought for a while, and returned the key to Yuhua.

"Hmph, see if I don't tell Sister Taichu about this in the future. Xiao Zi waved her fist indignantly.

"Alright, go in. Yun Fei stretched out his hand to grab Xiao Zi and plunged headlong into the spatial gap.

Yun Fei naturally didn't return the key to Yuhua because of the strange reward that Yuhua promised, but since he was able to enter the Heavenly Spirit Tree Realm by himself, there was no need to dominate the key;

Yuhua looked at the key in her hand, and she also had mixed feelings for a while, she didn't expect Yunfei to really return the key to herself.

"Could it be that I thought of him too badly?" Yuhua asked silently in her heart.

"Sister. Yuning tugged at Yuhua's sleeve, "Let's go in too." ”

"Good. Yuhua came back to his senses, breathed a little, and then pulled Yu Ning into the spatial rift.

The glowing green light emanating from the dendritic key shielded the siblings, allowing them to pass through the spatial passage without any resistance.

This is a mysterious space filled with pure air, and the light of unknown origin spills down from the height of the space, making everything here clearly present in front of Yunfei and Xiaozi who have just stepped here.

Everywhere you look, there are dense towering trees, which are connected like an ocean, and you can't see the edge at a glance.

Yun Fei stepped forward and gently put his hand on the big tree closest to him, and a sense of insignificance like floating dust arose.

"...... in this tree" Yun Fei's eyes flashed slightly, and an incomparably pure Xuan Qi poured in from that tree and plunged into Yun Fei's body.

"Absorb it effortlessly?" Yun Fei was taken aback, "This quality of Xuan Qi can already be comparable to the Xuan Qi produced by the Five Rank Exercises, right?"

Looking at the dense and endless towering trees in front of him, the shock in Yun Fei's eyes gradually turned into fear.

"This Heavenly Spirit Tree Realm is too terrifying. Yun Fei couldn't help but swallow his saliva, "This scale is too amazing!"

"Sha Sha ......" The footsteps of Yuhua and Yuning's two siblings came from behind him, "You misunderstood, not all trees are pregnant with Xuan Qi and soul fluid." ”

"Huh?" Yun Fei looked back at the siblings.

Yuhua said: "Outside the Heavenly Spirit Tree Realm, almost one-third of the trees are the real Heavenly Spirit Trees we need, and there are not a lot of Xuan Qi and Soul Liquid in these trees. The further you go in, the more amazing the energy contained in the trees becomes, but correspondingly, the number of Celestial Spirit Trees will also decrease. ”

Yunfei nodded, I see. But even then, the scale is quite staggering.

Yuhua continued: "I repeat, the Heavenly Spirit Tree is divided into the Heavenly Xuan Tree and the Heavenly Soul Tree, the Heavenly Xuan Tree contains Xuan Qi, and the Heavenly Soul Tree is full of soul liquid. ”

"Understood. Yun Fei nodded slightly, Yuhua had already said it once before, and now he emphasized it again.

Yuhua said: "Then let's separate here, the time of each appearance of the Heavenly Spirit Tree Realm is uncertain, everyone hurry up and hurry up to collect the Xuan Qi and Soul Liquid, and when the Heavenly Spirit Tree Realm is closed, we will be sent back to the entrance of the space just now by this space." ”

"So what are you waiting for? Xiao Zi immediately couldn't wait to urge Yun Fei to go quickly.

"Oh, yes. Yuhua stopped Yun Fei again, "I forgot to remind you, according to the information I received, Rong Gong, the leader of the Daoyuan Mercenary Group, has already found the Splitting Stone Mercenary Group, and they have a grudge against both of us, if you meet here, be careful what they do to you." ”

Yun Fei nodded and arched his hand at Yuhua, "Thank you for informing, Yun Fei wrote it down." ”

After saying that, Yun Fei took Xiao Zi and flew away, widening the distance between him and the Yuhua sisters and brothers.

"Master, this Yuhua won't really be interested in you, right?" Xiao Zi kept looking behind her, for fear that Yuhua would follow.
