The mussel was considered to have done an excellent job as it could dig half a mile of railroad in an hour.
"Mussel, have you been staying in the fifth mountain since the beginning and left before?" Gu Xijiu highly suspected the possibility.
"Yup." The mussel added, "I’m a mussel, I don’t have to go out."
Indeed!
Gu Xijiu smacked her head as she wanted the mussel to dig a path to the upper ground. However, she seemed to have sensed something. She walked further and placed her fingers on the freshly dug wall.
There was something on the wall!
Since it was just soil, she took out a blade and poked it. However, the blade could only penetrate about an inch into the wall and stopped. Something in the wall was restricting the penetration.
The blade could even penetrate an iron wall in a single poke, not to mention the soil. However, there was something stronger than metal behind it!
She simply scraped away the soil and finally saw the object in the soil, it was a layer of transparent membrane. The blade bounced back when she poked it, what was that?
"Wizardry barrier! Master, this is a wizardry barrier!" The Firmament Stone screamed in Gu Xijiu’s mind.
Wizardry barrier!?
Gu Xijiu heard about it before; rumor has said that the monk who had a very high spiritual power could set a wizardry barrier and it could block whoever or whichever living things from entering or escaping. It was stronger than any wall. However, wizardry barriers were usually set above the ground. This was her first time seeing a wizardry barrier underground.
Apparently, the wizardry barrier was set to prohibit any form of entrance and exit.
Gu Xijiu touched the barrier with her fingers and realized that should be at the fifth peak. She wondered whether the sixth, seventh, and the eighth peaks were forbidden sites.
She looked at Si Chen who was touching the barrier as well; he sighed, "The mussel is just like you, it got lost and went the opposite direction! This is the border of the fifth and sixth peak. The sixth peak and above are forbidden, and no one could enter or exit, this is why the barrier is here."
Gu Xijiu was speechless.
Initially, she did not immediately believe him, but she noticed what he said was true when she teleported to the upper ground. She was standing on a yellow ground, and everything at the wizardry barrier was in orange. Once she got out to the upper ground with Si Chen, they saw a huge orange beast glaring at them near the barrier.
Its eyes were bigger than the lanterns in the palace, and they were glowing with a blaze! It raised its head and gave a long howl when it saw Gu Xijiu and Si Chen and then issued a fire towards them as it opened its mouth!
Fortunately, the fire was blocked by the wizardry barrier. Otherwise, the forest would have been burnt to ashes.
Gu Xijiu took a step back, "What kind of beast is this?"
"The Heaven Floating Wings." Si Chen held her hand and stepped backward, "The Six-eyes Spotted Killer Centipedes which you killed is its food. The two centipedes you bumped into should have escaped from the sixth peak. They are merely the food for the Heaven Floating Wings when they are in the sixth peak, but they could be the king when they go to the third peak…"
In just a few seconds, the Heaven Floating Wings hit its claw on the ground and hissed! A huge Six-eyes Spotted Killer Centipede was caught and pulled out from the underground.
The Heaven Floating Wings tapped its claw on the centipede a few times, and it immediately became as weak as an earthworm. It was then eaten by the Heaven Floating Wings.
Although Gu Xijiu was brave, she could not resist trembling as she watched the bloody scene.
She almost died when she fought against the centipedes earlier. If she had to fight with the Heaven Floating Wings, she might not even have a chance to run!
"Scared?" Si Chen was holding one of her little hands and sensed the coldness of her palm. He tapped on her hand and said, "Don’t be afraid, I’m here."
Gu Xijiu remained silent, but the Firmament Stone kept nagging, "What can a troublemaker contribute?"
Perhaps, the beast in the sixth peak was too ferocious, those beasts in the fifth peak were nowhere to be seen. Therefore, the border was a rare and safe place.
Since Gu Xijiu knew the beasts in the sixth peak could not come into the fifth peak, she did not hurry to leave but observed the beasts in the opposite direction for a while. The Heaven Floating Wings looked like a winged dragon, it seemed very eager to break into the fifth peak as it kept blowing fire towards the barrier, but the barrier was as solid as molten gold. Even though it had been working hard to destroy the barrier, there was not even a tiny crack on the surface. That pissed it off and caused it to roar continuously until the ground was shaking.
Gu Xijiu gradually got more relaxed and sat on a huge rock.
Si Chen looked at her, "What are you doing?"
Gu Xijiu was in a position of meditation, "I’m thinking to restore my energy before I start to run again." She has been running around since she landed in the Dark Forest and she was too busy to rest. She was exhausted! Although she had a short break in the underground earlier, there was insufficient spiritual energy underground. Her meditation only helped her to restore her physical energy but not her last bit of spiritual power.
The border of the fifth and sixth peak was rich in spiritual energy, coupled with the absence of beasts; she could peacefully restore her spiritual power.
Si Chen sighed, "You’re such a brave girl."
After all, not everyone dares to take a break there. The overlord of the Yinyang clan who had a level eight spiritual power accidentally came to the border as well. However, she was frightened and escaped immediately without any hesitation when she saw the beasts in the sixth peak.
All the while, Gu Xijiu was the weakest among all the people who came here, but she was also the bravest person. She was brave but not reckless. She could always find a way to escape from the danger regardless of the seriousness of the situation.
This little girl is a unique one!
Si Chen had seen at least 800-1000 female assassins before, but none of them were so unique. What did she use to be before she was reborn?
Si Chen looked at her and idled.
Although that place was relatively safe, they could hear the scary roars from the surroundings. Even the Firmament Stone which had so many years of experience wanted to hide somewhere. However, Gu Xijiu was very calm and able to get herself into the peaceful, meditative state.
Was this little girl is too young and naive? While that place was relatively safe, it was not completely safe. Some reckless animals would wander around once in a while.
When Si Chen was thinking about her uniqueness, Gu Xijiu suddenly opened her eyes and jumped up, "Damn! I forgot something."
She waved at Si Chen who was looking at her, "Come, help me."
Si Chen was curious and got up from the ground, "How can I help you?"
A moment later, he finally understood. Gu Xijiu had chopped some wood and placed it on herself. However, the way she arranged the woods was very special.
Si Chen asked her as he was helping her to move the woods, "What kind of arrangement are you trying to set?"
"Safe Wind Array, it can withstand attacks from beasts." Gu Xijiu told him honestly without any reserve.
Si Chen thought he was very knowledgeable, but he found it quite interesting as that was his first time knowing about this array. Thus, he also tried to study the arrangement while moving the woods.
