After jumping into the corridor, the five people followed the thousand-handed corpse worm closely, because of its large size, the corridor it traveled through also seemed very wide, and it was more than enough for the three people to walk side by side.

They were not side by side, Feng Xuan walked in the front, Jing Chen and Xuan Mo were weaker and walked in the middle, Xuan Lin and Hei Yu were in charge of the back of the hall to prevent any accidents from happening.

In order to ensure that the five people could keep up, the speed of the Thousand Hand Corpse Worm was not fast, and after walking in the wide corridor for nearly ten minutes, the surrounding air became hotter and hotter, and with each step, the temperature of the air gradually increased.

Black Feather's sweat continued to drip down his temples, and so did Xuan Lin. Jing Chen and Xuan Mo are okay, both of them have Huo Yuan Qi in their bodies, and they are not so sensitive to temperature.

The road leads to the underground, but it is not a large round pit that is straight, and you can feel the obvious slope when you walk on the road.

This is also the reason why they haven't arrived after walking for so long, and the thousand-handed corpse worm is also taking care of the four children when they walk like this, they can't float in the air, and they still need to use this road when they come up for a while.

Just when everyone was about to lose patience, the huge body of the thousand-handed corpse worm finally stopped.

"Whew"

The Thousand-Hand Corpse Worm shouted loudly, as if to remind everyone.

"It says let's get ready, we're about to leave the road, and when we get out, there's a sea of mandala fire below, don't fall down, it won't be able to resist the heat there for long!" Black Feather explained.

At this time, Black Feather seemed to have become a translator, and every word the Thousand Hands Corpse Worm said he needed to translate to the four of them.

The palm of Feng Xuan in the front is sealed, and a wind wall will be in front of Jingchen and Xuanmo, and the exquisite wind wall just blocks the road. According to his estimates, this place is nearly a kilometer away from the ground, which is already very deep underground.

Jing Chen secretly praised in his heart, only when the control of Yuan Qi reached a certain level of subtlety could such an ingenious wind wall be formed in such a small space.

"You guys stay in the back first, if you find something wrong, turn around immediately, go back to the ground first!" Feng Xuan did this out of concern for their safety, and the road was over, but he didn't know where it led.

After taking precautions, the Thousand-Hand Corpse Insect no longer hesitated, and with a force of its body, it broke the barrier formed by the sand at the end of the road.

A fiery breath struck like a storm, and the Thousand-Hand Corpse Worm seemed to be accustomed to such high temperatures, and did not react in any way.

Feng Xuan's Yuan Qi automatically gushed out from the dantian, forming a Yuan Qi armor that resisted all the heat waves.

Thanks to Feng Xuan's wind wall, the heat wave failed to penetrate the defense of the wind wall, and the surrounding temperature still increased by a few degrees in an instant, and the underground seemed to be like a steamer.

After the heat wave passed, everyone settled down and carefully observed the surrounding environment.

The first thing I saw was a sea of red fire, with magma surging underneath, crashing against the surrounding rocks and causing waves of fire.

At the exit of the road, there is a red boulder platform, which is tens of meters away from the sea of fire below.

In the middle of the fire, a dark blue mandala flower floated strangely, its roots deeply rooted in the fire.

The four children were completely shocked by the scene in front of them, and it was the first time they had gone underground and seen this brilliant sea of fire.

To see such a spectacular scene, it is not in vain to go thousands of kilometers underground.

Jingchen saw the blue mandala flower at first sight, the blue flower body was very conspicuous in a sea of fire, I didn't expect that the fragile flower could really grow in the fire, and the flower that could withstand the quenching of the fire was really so easy to absorb?

The boulder platform they were standing on was still some distance away from the blue mandala flower, and in order to pick the mandala flower, they had to fly from the boulder platform to the middle of the fire.

"Well, Elder Feng, it seems that the mandala flower can only be handed over to you. Jingchen gently supported his forehead with his palm and said in a low voice. In addition to the thousand-handed corpse insects that can fly here, the only one that can fly here is Feng Xuan.

Feng Xuan shook his head and sighed softly, "Alas, this really can't be handed over to me. After speaking, he looked at the thousand-handed corpse insect helplessly, and his eyes wandered back and forth between the thousand-handed corpse insect and the blue mandala, as if to say that only this big guy could pick this blue mandala.

Jingchen was a little puzzled, and asked incredulously: "Feng Lao, are you saying that this mandala flower can only be picked by a thousand hands corpse worms?"

Feng Xuan nodded, and then said, "Do you know why the spirit body of the Thousand-Hand Corpse Worm was injured?"

The heads of the four shook in unison like rattles.

The reason for the injury of the spirit of the thousand-handed corpse worm, even if it is related to this mandala flower, it should not be picked by it, Feng Xuan's strength is much higher than that of the thousand-handed corpse insect, it stands to reason that even if the mandala flower will be devoured, Feng Xuan's grasp should be greater than that of the thousand-handed corpse insect.

Feng Xuan smiled helplessly and shook his head, he was quite helpless for these children, and when he looked at them, he knew that he usually didn't read ancient books well.

"It is recorded in ancient books that the blue mandala flower is spiritual, and no matter where it is grown, it can only be picked by the person who sees it for the first time. If others make a rash move, the blue mandala flower will slowly wither shortly after being picked, and the medicinal power and huge fire attribute elements contained in it will also disappear. ”

Feng Xuan slowly explained that he usually studied some books that recorded rare medicinal materials, and the blue mandala flower also belonged to one type of medicinal herb.

After hearing Feng Xuan's explanation, Jingchen was a little anxious, and hurriedly asked: "Feng Lao, the first person who saw it, then when I get it again, won't it also wither." ”

Feng Xuan waved his hand and said, "Only the first person who sees it can pick it, and there are not so many restrictions if it is available." ”

There are detailed records of the blue mandala in ancient books, and it is understandable that Jingchen does not know this.

Jingchen nodded slowly, and was even more surprised in his heart, he didn't expect that there was such a big knowledge in a blue mandala, it seems that he needs to study the treasures in the ancient books in the future, if he encounters it in the future, because of improper operation, the baby will be damaged, and it will be too late to cry at that time.

"Uh, Grandpa Feng, but the Thousand-Hand Corpse Worm is not a human, it is a strange beast, so is it the first person to see the Blue Mandala?" Black Feather's inquiry sounded unexpectedly, and the little face looked at Feng Xuan very seriously, not understanding what Feng Xuan had just said.

Jingchen glanced at Hei Yu, slapped his forehead with his palm, and lowered his head helplessly. This guy always asks these brainless questions, he is still a strange beast himself, and I haven't seen him not see him as a human being.

The other three were amused by Black Feather's sudden question, and the Thousand-Hand Corpse Worm also made a gurgling sound.

Feng Xuan walked up to Hei Yu, patted Hei Yu's shoulder gently, and said, "Xiao Yu, the people here are just a concept, referring to all living things. ”

Xuan Lin learned from Feng Xuan's example, walked to Hei Yu's side, patted him lightly on the shoulder, and said, "Xiao Yu, when you get out of here, we will take you to see the best doctor." ”

Xuan Mo smiled coquettishly, covering his mouth with his little hands and not daring to speak.

Hei Yu looked at everyone with a stunned expression, and he couldn't help but laugh along.

After the joke, Feng Xuan continued: "If you look closely, the petals of the blue mandala have been missing a few leaves, presumably absorbed by the Thousand Hands Corpse Worm, and its spirit body should also be injured because of this. ”

Following Feng Xuan's gaze, everyone looked at it, and sure enough, the petals of the blue mandala were missing by nearly half. Half of the face has only a few petals, and the other half is no different from ordinary petals, which looks unsightly.

The thousand-handed corpse insect is not a human, so it does not consider the beauty of flowers, and according to habitual thinking, it will always pick it close to one side.

Fortunately, what Jingchen needed was not the petals of the blue mandala, and if he wanted to absorb the fire element essence in the flower, he still had to eat its flower heart to be effective.

"Xiao Yu, you communicate with the Thousand-Hand Corpse Worm and let it go over and pick the blue mandala, it's not safe here, there is something strange hidden under the sea of fire, we just wait for it here." Feng Xuan whispered in Black Feather's ear, for fear of being heard by the Thousand-Hand Corpse Worm.

Its intelligence was now quite high, and it was not surprising that it could understand a human sentence or two, and the Thousand-Hand Corpse Worm seemed to understand a little when they laughed earlier.

Black Feather nodded, and conveyed Feng Xuan's meaning to the Thousand-Hand Corpse Worm.

The latter was secretly happy in his heart because Xuan Mo agreed to its request, so naturally he didn't dare to offend them, anyway, with Hei Yu as a guarantee, it didn't have to worry that these humans would backtrack.

With the support of its tentacles, its huge body leaped deep and flew towards the blue mandala flower in the middle of the sea of fire...
