The exchange period flew by, and as the final few days approached, Lin Feng and the others gathered together again.

"I've made up my mind. Once we get out, I'll go on a rating upgrade mission." Si Zang firmly stated his idea after meeting him.

"I'm almost there too, but I need to return to the previous mission world," Tang Hong said slowly, somewhat reluctant to look at the smug look on Si Zang's face.

Yu nodded and took out the seven-level pagoda that Lin Feng had given her. In a blur, the seven-level pagoda resonated with her in some kind of magical way, even more so than it had in Lin Feng's hands.

"I also received the notification."

Lin Feng responded to everyone, saying that the Nightmare Space had already issued a prompt to upgrade his rating task the moment he left the Lingxiao Palace.

"Haha, we're pretty fast, aren't we? We haven't even entered the mandatory Earth-level mission yet, and we've already received a notification?" Si Zang laughed, his eyes darting back and forth between the group.

"The upgrade will bring trouble. The Evil Origin Path and the Yin Sitian people won't let us off the hook," Lin Feng warned. "And what about Sun He and the others? If they're unwilling to upgrade their ratings..."

"Should we wait a little longer?" Tang Hong suggested.

After a brief silence, Lin Feng shook his head: "No need to wait, they won't be too different."

Even though Sun He and his group had only recently started working with them, there was no mandatory correlation between their ratings and their individual abilities.

Si Zang sighed, "It's really worrying that seven people are entering the mission world. What if three or four teams come? They might cause a huge disaster."

"Regarding this matter... we should focus our main efforts on improving our strength and rating." Lin Feng explained seriously, "The struggle at the prefecture level involves personal ideologies. Sun He joined us not only because he is similar to us, but also because we can provide him with some protection. However, the increase in numbers should not be a reason for us to escalate the struggle without cause."

“Hmm…” Si Zang nodded repeatedly, while Tang Hong and Yu both seemed to be deep in thought.

"Of course, he is unaware of our conflict with the Yin-Yang Stream, nor of the Evil Yuan Path and Yin Si Tian that we will face in the future... But precisely because of this, we must be even more cautious, even if they are willing to help us join forces against the enemy."

"Oh?" Tang Hong asked, puzzled. "Why?"

Lin Feng continued, “We do have conflicts with these forces, but it’s not a full-scale war. So our goal is to improve our rating as soon as possible and take the opportunity to achieve our objectives, rather than getting involved in this mess and being further dragged into the vortex between these forces, unable to extricate ourselves.”

"Oh!!!" Tang Hong suddenly understood; so that's what it meant.

"Hmm~ that makes sense, that makes sense!" Sizang nodded heavily. "But... it's not that easy, is it? Reaching the Earth level isn't that easy either..."

As he spoke, Si Zang deflated, thinking that if he were sent to a world with a great calamity, who knew what kind of great catastrophe he would enter next time.

"What I mean is that our goal is to improve the rating, not for you to improve the rating right now," Lin Feng explained helplessly. "Whether or not we enter the mission world, we don't need to be too aggressive just because the number of people is increasing."

"Hiss, are you planning to trick them?" Some thoughts suddenly popped into Si Zang's mind.

"It's not a trap," Lin Feng said helplessly. "After all, they are teammates. If we trap them, it's the same as trapping ourselves."

"Fourth Brother, calm down. If Si Tao doesn't listen, he'll definitely be the first to make a move," Tang Hong warned silently. As soon as he finished speaking, Lin Feng's eyes widened.

Yeah, those two have a personal grudge!

Although it wasn't a major personal grudge.

"Hahaha, peace and peace, I understand now." Seeing that his little scheme had been exposed, Si Zang immediately put away his previous expression.

“Um…” Lin Feng glanced at it again and changed the subject, saying, “I’ve been studying the will attribute during this time. Theoretically speaking, our will can change. As long as we find a special point of change, a new will attribute can appear.”

“It’s not that simple,” Shizang retorted without hesitation.

“Sun He’s will can be divided into Yin and Yang, so there must be other methods.” Lin Feng ignored Si Zang and continued, “One Qi Transforms into Three Pure Ones, Soul Division, Body-Outside-Body Technique, Second Avatar, Divine Avatar, Second Primordial Spirit... these techniques may be able to greatly improve your strength.”

"Ahem, whatever. Once the second consciousness develops its own will, that's a different story." Si Zang shook his head and said, "If the clone has independent will attributes, there is a high possibility of conflict of interest."

They're not like you. If number 78 can behave, that's incredibly lucky.

"So my suggestion is to use the changes in will attribute to expand the second will attribute." Lin Feng explained, "Your own beliefs, your beliefs in controlling the Dao, can all be used to differentiate different will attributes."

Seeing that Si Zang was somewhat indifferent, Lin Feng didn't dwell on him any longer. If things got really urgent, this guy would want to gain the Willpower attribute more than anyone else.

“Yu, the body of the Ghostly Calamity is just a destiny. It can be seen as the manifestation of the will of heaven and earth imposed on you. You can accept it and control it, just like the Fangxiangshi Mask. There are also new changes behind these things.” Lin Feng said carefully, and Yu listened very attentively: “In other worlds, this power will also be seen as a great cleansing of all things by heaven and earth. Don’t just focus on the destructive side.”

"He really does seem like an old father now," Si Zang whispered to Tang Hong, his voice carrying unreservedly to everyone's ears.

Tang Hong rolled his eyes at Si Zang, then said, "If Sun He's Yin-Yang transformation can be further differentiated, he might be able to create things like one begets two, two begets three. I think he's been hiding his true abilities."

“Si Tao is the same.” Lin Feng agreed wholeheartedly, then casually added, “He also has some tricks up his sleeve.”

Very strong!

Lin Feng's eyes subtly shifted to Si Zang, the meaning of which was self-evident: Your nemesis is in danger.

Before Si Zang could jump up, Tang Hong continued, "The boxing techniques I've learned record similar transformations, as do Taoist practices. Yin alone cannot grow, and Yang alone cannot be born. However... what I pursue is not change."

There are explanations for the changes in all things caused by the interaction of Yin and Yang, but there are also explanations for the destruction of all things and the dissipation of Yin and Yang.

“Perhaps before we upgrade our rating, we should go to an unconventional world,” Tang Hong suggested. He had an idea, but no suitable opportunity: “Things that are too conventional are no longer of any practical help to us.”

Lin Feng's mind raced, and he agreed, "Okay, then let's go first, and then split up?"

"Hey, wait a minute, should we take Sun He and the others with us?" Si Zang suddenly interrupted their conversation. "Why don't we let them take us? What if there's some interesting world out there?"

"You..." Tang Hong rolled his eyes, too lazy to say anything. Clearly, Si Zang had been bored out of his mind during the past year.

“Hey, I think they hold a special opportunity for us. Why don’t we give it a try?” Si Zang ignored Tang Hong’s scolding and leaned closer to Lin Feng: “Sun He was a person from the late Yuan Dynasty. In such a long time, he must have experienced most of the mission worlds in the Nightmare Space. Who knows what good things he might have to discover.”

Lin Feng pondered for a moment and said to Tang Hong, "Yes, we do need more contact. It will not only facilitate cooperation but also help us understand each other."

"Haha, I guess they're waiting for us to ask them first," Si Zang chuckled. "They just have no idea we want to enter an unconventional world."

"Will we encounter people from the Evil Yuan Dao or the Yin Si Tian?" Tang Hong asked.

"I think so," Lin Feng replied. "It's time to make contact with them."

"Wait!" Shizang suddenly calmed down for a moment: "They probably won't give us the Nightmare Invitation Letter directly."
