() Rong Xian Xian carefully searched around this underground space, but did not find any ice crystal trees.

While disappointed in her heart, she couldn't help but laugh at herself, letting a young bird show the way, it was really a shame that she thought of it.

Looking up from the position where they were floating, all they could see was a small, narrow slit, distant and small, with a faint light.

The flying carpet is a big consumer of spiritual energy, with the current realm of Rong Xianxian, it is easy to control the flying carpet by himself, but adjusting the flying carpet to the maximum mode, plus Cui Lie and the two children floating like this, the consumption of spiritual energy in the body is more obvious, I am afraid that it will not last long, and I have to find a safe place to settle down.

Slowly, Rong Xian Xian and Cui Lie's eyes adapted to the underground environment, and even in places where the strong flashlight did not shine, they could see the surrounding scene vaguely.

"Ah Lie, the gap above is so narrow, how can the light shine so deeply?" Rong Xian Xian asked suspiciously.

If it was only the light that came through that gap, I would not be able to reach out and lose my fingers at such a deep place.

"Chirp, tweet." The whoop who landed on Xuanxuan's shoulder was unwilling to be lonely and screamed twice, and then flapped his wings and flew upward.

"Mom, let's keep up." Xuanxuan urged.

"Sister Rong, there is an aperture in the middle of the rock wall on the left, and the light is projected from the right rock wall to the left rock wall, and it is reflected and scattered." Cui Lie pointed to the rock wall on the left and interrupted, the brightness there was indeed stronger than elsewhere.

"Let's go, Sister Rong, it should be the middle of the rock wall on the right side that took us, let's see what is there?" There was some expectation in Cui Lie's tone.

"Okay, I'll be on guard later, if there is an unknown attack, be sure to block it, and don't touch the defensive function of this flying carpet." Rong Xian Xian carefully advised.

The flying function of this flying carpet is very practical, but the function of defending against attacks is really a huge pit, consuming aura, and it is simply a bottomless pit.

The four of them are all attached to the vajra talisman, and they don't need the protection of the flying carpet, but as long as the unknown attack is close to the defense circle of the flying carpet, the flying carpet will automatically defend against rebound attacks, and there are many sneak attacks that are hidden and difficult to guard against, Rong Xian Xian has been sucked dry several times because of the automatic defense function of the flying carpet, and she has some shadows in her heart, and she doesn't know what realm she has to cultivate to meet the consumption of the flying carpet on the aura.

Rong Xian Xian controlled the flying carpet to fly in the direction of the howl guidance, and when it rose to the middle section, there was a crescent-shaped hole on the rock wall on the right, and the hole emitted a misty light, which seemed to be steaming out of misty water vapor, and like the hoarfrost sprinkled on the ground on a cold moonlit night.

Whoop happily flew into the hole.

Rong Xian Xian manipulated the flying carpet to stop at the entrance of the cave, a little hesitant, this light curtain is somewhat similar to the light curtain at the entrance of the small secret realm outside the Hundred Flowers Town, if this light curtain repels the flying carpet, in case they are overturned, in mid-air, it will be dangerous.

Rong Xian Xian was still hesitating, Cui Lie took a step forward and stepped in.

Rong Xianxian looked at Xiao Luo and Xuanxuan, and hesitated whether to let the child go in first or go in with her.

"Sister Rong, come and see." Cui Lie suddenly turned back from the light curtain, picked up Xuanxuan and Xiao Luo, and beckoned Rong Xian Xian to hurry in.

Rong Xian Xian's heart was a little warm, she knew that Cui Lie took the first step to prevent any danger at the entrance, and came to explore the way for her and the children.

"Wow, it's so beautiful here!" As soon as she stepped into the cave, Xuanxuan exclaimed in surprise.

Rong Xian Xian looked at the scene in front of him and was a little shocked, the creation of nature is really a miracle, this place looks like a natural cave, without any traces of artificial excavation.

This natural cave is more than ten meters long and wide, and the top of the cave hangs with stalactites of different shapes and sizes, and the surface of the stalactites is shining brightly, crystal white, exquisitely clear.

Compared with the deep and wide underground lake below, this cave area is not large, and I don't know how it was formed, there is a shallow puddle in the middle, the bottom of the puddle is paved with a layer of fine sand, and there is an ice crystal tree growing around the puddle, and there are a bunch of lilac ice crystal fruits hanging on it, the ice crystal tree, the tree is as its name suggests, the overall look is ice crystal-like white, the branches, branches, and the trunk are crystal clear and very beautiful.

Its leaves are fan-shaped, frost-like white, and the tree is low and fluffy, with many branches, and from a distance, it looks like clusters of corals on the bottom of the sea.

"Sister Rong, this ice crystal fruit is nothing unusual, although the taste is good, the aura contained in it is very weak, is there any other use for this ice crystal fruit?" Cui Lie asked puzzled, since embarking on the journey to the north, Rong Xian Xian and his party have already planned every move, perhaps because of the two young children, Rong Xian Xian is not an adventurous person, he found that the situation was not right, he thought that Rong Xian Xian would return immediately, but he didn't expect Rong Xian Xian to still come here.

"There is nothing unusual about the Ice Crystal Fruit, the strangeness is the sap of the Ice Crystal Tree, and the sap flowing in this trunk is a rare material that the master of refining dreams of." In another half a year, the task list of some large security areas will be updated one after another, and the sap of the ice crystal tree, also known as ice glue, is thick and sticky, smells fragrant, and is very expensive, making it a very sought-after rare material on the task list.

Rong Xian Xian also happened to hear a fellow uncle mention that his wife's maiden nephew was an apprentice to a refiner, and I heard that this ice glue can be used to bond all the materials commonly used in refining tools after heating, and it is a very powerful adhesive, which can improve the success rate of weapons and enhance the malleability of weapons when refining high-level weapons.

Cui Lie didn't ask Rong Xian Xian how he knew that the sap of this ice crystal tree was a rare material, everyone had a secret, and Rong Xian Xian was able to tell him frankly that this was a rare material, which had already given him great trust.

Rong Xianxian was prepared before setting off to find the ice crystal tree, and she took out a dozen water bags that were simply sewn with latex material, which Rong Xianxian had exchanged for a box of antipyretics when she was in Chongzhou District.

Rong Xian Xian used a knife to cut a hole under the trunk of the ice crystal tree, and put the latex water bag around the opening, and the sap of the ice crystal tree would slowly flow into the water bag.

Rong Xian Lisuo put on all the latex water bags, and looked at the water bags with satisfaction and filled them little by little, although the process was a bit thrilling, but with these gains, this trip was not in vain, it was worth it.
