The endless night sky, the barren land, the rocks and the wind and sand as far as the eye can see.

Chu Yi and his entourage have been walking for two hours, and the scenery in front of them has not changed in the slightest. If it weren't for Liu Nan holding the wind fixing plate, Chu Yi and the others might not even be able to find their way back.

"Teacher Liu, can you take a break first? Wen Xing, one of the students, said. It's not that Wen Xing can't walk, but the boring journey makes his spirit feel tired.

"Didn't you say a small dimensional cave, why is it so big?" Wang Yifei also shouted.

"Maybe it's not big, it's just that we're slowing down. Chu Yi pondered.

Chu Yi was right. Liu Nan praised, "Because there is no spiritual power in the dimensional cave, our perception and speed will decrease, and this is precisely the most dangerous point. Now we are not far from the Dazzling Passage, and the danger factor is not high, but everyone should not take it lightly, walk a little longer, and after entering the middle of the dimensional cave, we will make adjustments. ”

"Teacher Liu, as far as I know, the brute beasts will stay in the depths of the dimensional cave until they leave, and they will not appear in our section of the road at all, so what are you afraid of?" Regarding the knowledge of the dimensional cave, Chu Yi has also made up for it in the past 2 days, although because of the rarity of the dimensional cave, the human race does not know much, but with the current records, the poisonous insects and alien beasts in the dimensional cave are not a big threat to Chu Yi and others.

"Have you heard of the 'Void Beast'?" Liu Nan said slowly.

"Void Beast?" everyone wondered.

"Could it be the legendary extraterrestrial monster above the Nine Heavens? Cai Wei, the quietest among the students, suddenly spoke.

"Well, go on. Liu Nan motioned for Cai Wei to continue.

"According to legend, Emperor Xuanyuan cast the Xuanyuan Sword, borrowed the power of the nine heavens, took the light of the sun and the moon, and it took 9981 days to complete, the day the sword was completed, the sky was punished by thunder, and black lightning fell straight down from the nine skies, and with the lightning fell, there were visitors from outside the sky. Cai Wei said unhurriedly, and paused when he said this.

"And then, what does the visitor look like and what is his strength?" the crowd hurriedly asked.

"No one knows, because what fell was actually a charred corpse. Cai Wei smiled bitterly and shook his head.

"This ......" Chu Yi and the others were speechless, the audience's appetite was hung out, and it ended like this? Everyone stared at Cai Wei with resentful eyes.

Xu felt everyone's murderous aura, and Cai Wei sped up his speech, "However, this confirms the speculation of some scholars, above the nine skies, under the sun and the moon, between the voids, there is another heaven and earth, and this heavenly visitor is the proof." Scholars have named the Outer Visitors 'Void Beast', but Void Beast has always existed in legends, and no one has ever actually seen it. Could it be that this Void Beast is related to the Dimensional Cave?" Cai Wei looked at Liu Nan and asked.

"Ten years ago, I entered the Dimensional Cave for the first time, and that time I encountered a monster. Liu Nan didn't answer, but said with a frightened face, "That monster can change its form with the environment, it may be a rock, or it may directly blend into the air. We didn't know it existed, and it wasn't until my companions fell silently one by one that we discovered the anomaly. At first, we were very panicked, until we found out that the monster was really weak when it attacked, and we only used one punch to get rid of it. However, before the monster fell, my companion lost nearly half of it, its stealth transformation ability is too strong, and it is good at cutting throats with one blow, and if you are not careful, you will be attacked. If you have spiritual power, you can find it with just one perception, but unfortunately we were in the dimensional cave at that time. I've never seen this kind of monster before, it's transparent, it's small, it has long hands and legs, and I've searched through the books to think it's the most similar to the Void Beast. It's like a hunter, patient, deadly, so I call it the 'Void Hunter'. ”

"I once announced my story to the world, but it was criticized by everyone, everyone thought I was grandstanding because no one had ever encountered such a monster, and I later participated in the exploration of the dimensional cave many times, and it turned out that this situation never happened again. Liu Nan said, "So you don't have to worry too much, maybe it was just an accident back then." ”

Liu Nan's words shocked Chu Yi and the others, it turned out that there were such unexpected things in the Dimensional Cave.

"Then what if there really is a Void Hunter?" Lin Jing was obviously a little scared.

"Don't worry, I've been watching along the way, and if there's any abnormal airflow, I'll be the first to strike. A hunter is no longer a threat if it is detected in advance. The Void Hunter is fragile, and if you pay more attention, find it out in advance, and give it a single blow, it will be enough to kill it. Liu Nan said.

Chu Yi and the others nodded, and on the next journey, everyone would observe left and right with every step, and the already unfast travel speed became slower, and Liu Nan, who was watching, shook his head. Liu Nan didn't plan to talk about it, but he was worried that the students would overreact, but now it seems that it is not surprising.

Another hour passed.

"There's a situation ahead!" Wang Yifei said suddenly. Wang Yifei was born with a keen sense of hearing, and after refining his body, he strengthened his training in hearing, and at this time, he clearly heard a faint shout in front of him.

"Location, distance?" asked Liu Nan.

"About 1,000 meters in front of the left, behind that rocky forest. Wang Yifei said with a wave of his finger.

"Awesome!" Chu Yi couldn't help but praise, without the bonus of spiritual power, Chu Yi could only hear movement within 500 meters at most, which was far from Wang Yifei.

"Speed up, go and see!" Liu Nan ordered.

"Yes!" Chu Yi and the others responded in unison, and the tension they had suppressed for a long time was finally released at this moment.

The group jumped over the rocky forest and arrived quickly. I saw a 3-meter-long giant centipede, fighting with a man and a woman, and behind the centipede, there was a small gray-white leafless flower.

"Heart-devouring flower!" Chu Yi recognized at first sight. The Heart-Eater Flower is a highly poisonous flower, which can be made into Heart-Eater Pills, swallowed like being bitten by a thousand insects, it can torture people to death, and it is extremely poisonous, and the giant centipede should be the guardian poisonous insect.

"Poisonous heart, and the Fu family. Liu Nan said. The Fu family is one of the big families of the Qiyun tribe and is famous for cultivating swordsmanship. At this time, the two of them were one on the left and one on the right, and the sword shadows were intertwined, and they were inseparable from the poisonous centipede, which was a set of joint fencing skills.

"You two, do you need help?" Liu Nan shouted. The Fu family and the others had also noticed that someone was approaching, and when they looked back, it was the Apocalypse Academy.

One of them replied in a busy hurry: "Thank you for your kindness, if there is a need, Fu will definitely ask for help as soon as possible." ”

"Be careful!" As he spoke, the poison-hearted centipede suddenly stood upright, and a mouthful of poisonous mist shot straight out.
