After hearing Yang Xiao's words, Xing Zhe couldn't help but shudder, and hurriedly ran a few steps forward, following Yang Xiao closely.
"Yang Xiao, do you think there should be a higher-level mountain cannon monster ahead?"
"It's not an estimate, it must be there. Moreover, the smaller mountain cannon monster I just killed is most likely the son of the monster with a higher evolutionary level."
"Damn it, if that monster knew that we killed its child, wouldn't it come to us to fight for its life?"
"What do you think?"
Yang Xiao didn't stop for a moment, speeding up and running forward.
However, you can't run too fast in this underground river tunnel.
The two ran back to the place where they had slept and rested.
Xing Zhe was about to jump ashore to rest, but saw Yang Xiao go directly into the cave of the underground river, dive into the water, and disappear instantly.
Xing Zhe didn't dare to stay, so he followed Yang Xiao into the water hole and walked forward.
They didn't know how long they walked until they returned to the six-winged centipede's cave. Only then did Yang Xiao jump up from the underground river and let out a long sigh.
"I'm so exhausted."
Xing Zhe also jumped up, lay on the ground, and said:
"Yang Xiao, do you think there are really higher-level monsters at the end of this underground river tunnel?"
"It never hurts to be on guard. Do you still remember the skeleton of the Qiluo tribe?"
"Well, what's wrong?"
"If I'm not wrong, Wu Feng accidentally broke into the monster's lair, was chased by the monster, and finally died there.
Wu Feng recorded his last words before he died, hoping that someone who would come after him would send a message to his tribe after seeing his body, and send back a very important jade pendant of their tribe's rune key to the defense light curtain gate.
It is estimated that the golden jade pendant is related to the life and death of the Qimo tribe, so he urgently recorded it beforehand. "
After hearing Yang Xiao's reasoning, Xing Zhe suddenly understood and nodded.
"Yang Xiao, your guess is correct. According to your guess, there must be another terrifying super monster in this underground river tunnel.
What are you going to do? Back to college? "
Yang Xiao thought for a while, sighed, and said with a smile:
"Xing Zhe, are you willing to go back?"
Xing Zhe was stunned and smiled:
"Of course I don't want to give it up. I still hope to break through to the intermediate level of the emperor here and then go back. There are so many good resources here. If we can find the source of the underground river water and practice for a period of time, we may be able to quickly break through to the intermediate level of the emperor."
"What's more important, life or cultivation?"
"..."
Yang Xiao and Xing Zhe both wanted to find the source of the underground river as soon as possible and then break through to the intermediate level of the emperor. After all, the evolutionary energy here is too powerful and difficult to find elsewhere.
However, when the two of them thought that there might be a super monster beast at the peak of the emperor level or even the holy level, they felt a little chill in their hearts.
The two chatted for a while, ate some dried fish from the flying goldfish, and then lay on the ground to sleep.
The two of them have lived in the Six-winged Centipede's cave for several months. They are familiar with the surrounding environment and can sleep peacefully.
"Bang, bang, bang,"
Yang Xiao was sleeping soundly when he was woken up by a deep sound in his daze.
Yang Xiao opened his eyes and glanced around the cave, but found nothing unusual.
Xing Zhe beside him also woke up.
The two looked at each other.
"Bang, bang, bang!"
Thinking of the dull sound again, Yang Xiao felt the rocky ground beneath him tremble slightly, and was shocked.
"Xing Zhe, do you feel anything?"
Xing Zhe was also frightened.
"I felt the ground shaking."
"I have a bad feeling,"
"That super monster came out?"
"Well, it's very possible that the super monster discovered that his son was killed by us, and is heading here along the underground river tunnel.
You hear the thumping and the ground shaking. "
Yang Xiao and Xing Zhe held their breath, feeling the atmosphere of fear.
"This tunnel is more than ten kilometers long. This monster won't be able to drill this long, right?"
"It's hard to say. If it wants to avenge its son, it will definitely get through. Even if it can't get out temporarily, it will continue to get in for several days."
"Then what should we do, and it's not very dangerous?"
"There is only one way, get out."
"Okay, it's time to go back. We have stayed here for more than five months. It has been long enough. The college must have thought we were dead."
Yang Xiao and Xing Zhe immediately jumped into the underground river tunnel, ran to the cave of the ghost snake, and then returned to the underground tunnel of the 101 training ground.
"Yang Xiao, I guess the monster won't be able to get through for a while. We have to find a way out now."
Yang Xiao smiled and said:
"It's a very simple thing to go out, don't worry, have you forgotten this?"
Yang Xiao took out the silver sword he picked up in the tunnel from the space ring.
Xing Zhe saw it and immediately smiled excitedly:
"With this magic weapon, it will be faster than digging holes by ourselves."
They had never heard the "bang bang bang" sound in the underground tunnel. Even in the underground tunnel of the 101 training ground, the two of them could still feel the slight vibration of the cave rocks.
The two of them did not dare to delay and went directly to the entrance of the tunnel that was blocked by rubble.
"Xing Zhe, I use my sword to smash the rocks in the tunnel in front. You carry the gravel backwards behind me and fill it into the tunnel behind me."
"good!"
Yang Xiao held the silver sword and injected it with genetic evolution energy. A sword energy tens of meters long suddenly surged out and pierced directly into the rubble of the tunnel ahead.
Yang Xiao held the long sword and stirred among the gravel. The huge stones were cut into small pieces one after another.
Xing Zhe stood behind him and with a move of his hands, the rocks shattered by Yang Xiao formed a long dragon of gravel and flew backwards one after another.
Xing Zhe waved his hand and threw the rubble into the tunnel more than a hundred meters behind him.
The two of them cooperated like this and kept digging the tunnel forward.
Although it was just some rubble, there was originally a hundred-meter-high hill above the 101 training ground. After the whole was blown up, a large number of stones collapsed, covering up the entire 101 training ground. Yang Xiao and the two wanted to destroy this cave. It won't be possible to get through it in a short while.
What's more, the gravel will roll. Yang Xiao will crush some of it. As soon as he digs out a short distance, the surrounding gravel will roll down again and fill up the entrance of the cave.
The two of them were running the energy of genetic evolution for such a long time, which was very debilitating. They had to stop and take a break after working continuously for an hour.
There is no concept of time in the cave. When you are tired, take a rest and continue working after you have rested.
When the two stopped to rest, the "bang bang bang" sound of the underground river was still coming.
And there is a feeling that it is getting louder and louder, and even the trembling on the tunnel ground has become a little stronger.
Xing Zhe scolded:
"Damn it, this monster keeps drilling holes, and it seems it has to eat us."
"Nonsense, if someone kills your son, won't you try your best? Work quickly and get out early, otherwise, we will become food in the mouth of the monster."
Set a small goal first, such as remembering in 1 second: Shukeju
