The Rock Insect kept coming their way, but Yi Tianyun didn't seem to care as the Rock Insect didn't possess any threat.
Xu Fei, on the other hand, was busy gathering the corpse of the fallen Rock Insect in excitement. He now will be able to sell the material from the Rock Insect for some gold and even could create several high-grade Medicinal Pills or Tools if he wanted to!
"Big Brother Yi, I sense imminent danger from the rock over there!" Xu Fei said as he warned Yi Tianyun.
Yi Tianyun immediately smashed the rock that Xu Fei had pointed and sure enough, a Rock Insect was killed instead of a normal rock!
"You're as sharp as usual! Keep those advantages coming!" Yi Tianyun said appreciatively.
Yi Tianyun knew that the Heavenly Clouds Mansion needed a lot of manpower by this moment, so he had thought of bringing Xu Fei along later if Xu Fei agreed to that!
He wanted to observe Xu Fei further as he could increase Xu Fei's favourability and increase his chance to bring Xu Fei to Heavenly Clouds Mansion later.
"Understood, Big Brother! I will keep observing!" Xu Fei said excitedly.
But there was no danger around them anymore, at least until they arrived at the four clover door at the end of the tunnel.
The doors looked menacing while they had different symbol etched on them with different size, with the smallest door didn't have any symbol on it!
From the largest to the smallest it said: Human Level, Earth Level, and Heaven Level!
There was no doubt that this place has been divided into three levels of difficulties, but Yi Tianyun was interested in the small door, as he could feel the Spiritual Energy around the door was quite dense!
"This is Four Clover Door! I Heard that they have a different treasure that corresponds with their difficulties while the hardest was the smallest door! I heard that the smallest door was so dangerous that no one ever made it out!" Xu Fei explained.
"Well, are you going in?" Yi Tianyun asked.
"Of course, big brother! I have to take a look after coming this far, aren't I?" Xu Fei said excitedly.
"Well, what door will you choose?" Yi Tianyun asked.
"I think I will enter the Earth Level! I don't think I could handle the Heaven Level with my current cultivation!" Xu Fei said confidently.
Yi Tianyun nodded his head as his admiration towards Xu Fei kept growing, Xu Fei has already grasped the level of his own strength and thus bravely took a risk but not as much that he couldn't handle!
"What about you, Big Brother Yi? Which door will you choose?" Xu Fei asked curiously.
But as Yi Tianyun was about to answer Xu Fei's question, another group arrived, distracting them both.
"Xu Fei! I didn't expect to see you here! The world sure is small!" A handsome young man said suddenly.
"Wang Menglong! I didn't expect to see you here either!" Xu Fei said heavily.
"Relax, there is no need for you to be nervous, I am not here for you!" Wang Menglong said as he made way for a beautiful woman to walk into the room.
The woman was staring at the smallest door.
Yi Tianyun immediately used his appraisal eye to obtain the information of the man and the woman who just came in, he saw that the woman was at 9th Level Spirit Core Stage, while the man was at 7th Level Spirit Core Stage.
From the look of it, the man was here to protect the woman, but Yi Tianyun wasn't so sure anymore as the woman was more powerful than the man anyway!
"I didn't expect Hua Xiying is also here either!" Xu Fei said a bit heavily.
"I am here to cultivate, while I am also here to search for any clue of Great Emperor Ren's whereabout, I Hua Xiying has chosen to stand beside the princess!" Hua Xiying said confidently.
Yi Tianyun didn't really care about anything that the woman and the man had to say as they didn't pique Yi Tianyun's interest.
Instead, he shifted his attention back to the Four Clover Door, from Xu Fei's information, it seemed that every door except the smallest one had been successfully cleared by other cultivators!
He also knew that according to Xu Fei's information, the harder the level, the better the reward!
But as what reward he could get was still completely unknown!
Yi Tianyun made a mental decision on which door that he wanted to pick, there was no need to ask in the first place!
