Yin and Yang were the innate Qi of creatures of both sexes, including humans. For humans, male possessed the Yang Qi while women possessed the Yin Qi.
'According to the message from the jade token, if people with Yin and Yang Qi appear at the same time within 1,000 meters of the entrance of the Little World, they would be pulled into the Little World. The Formation did not distinguish between humans and beasts as long as each possessed Yin and Yang Qi. However, beasts, or non-human creatures, would die as soon as it was pulled in by the spatial turbulence. A single human could also enter the Little World, but without a person of the opposite sex, they would be killed by a Killing Formation. Duan Ling Tian was truly startled by this information. He thought to himself, 'During this 10,000 years since the Little World was discovered, there must be many people who had accidentally triggered the Yin and Yang Reversal Formation and had been forcibly pulled into the Little World because there were other creatures or beasts of the opposite sex within 1,000 meters of them.'
As Duan Ling Tian looked around, he saw a corpse with only the lower part of its body left. A Spatial Ring and an identity token lay next to it. After he used his Celestial Origin Energy to collect the identity token, he narrowed his eyes. The identity token was black with a dragon's head carved on its front with the three words, 'Black Dragon Army'. On its back, the body of the dragon was carved on it with the word, 'Captain'.
'This token… So this corpse belongs to the Captain of the Black Dragon Army. It seems like he was really pulled into the Little World by the spatial turbulence. Since there's only his corpse in here, it must have been a female creature that triggered the Formation. How unlucky!' Duan Ling Tian thought to himself. Then, he kept the identity token and Spatial Ring of that Black Dragon Army's Captain. After making the ring his own, he looked into the Spatial Ring and found a Celestial Saber, some strange materials, Primitive Celestial Stones, and Mediocre Celestial Stones. Needless to say, the Captain of the Black Dragon Army had more Celestial Stones compared to the Decurion of the Silverwyrm Army whom he had killed.
"Unfortunately one would be transported to different places in the Little Word. Otherwise, I would be able to collect more Spatial Rings," Duan Ling Tian muttered under his breath after sighing.
'However, what's the point of having so many Celestial Weapons and Celestial Stones if I can't leave this place?' Duan Ling Tian smiled bitterly as he thought about this. 'No wonder she said she would die if she killed me. As it turns out, if the members of the opposite sex don't stay within 1,000 meters of each other after entering the Little World, they would die. If one dies, the other will also die.' Duan Ling Tian finally understood the woman's words.
The woman replied curtly, "The powerhouse who left this Little World behind was a Superior Celestial King!"
"Celestial King?" Duan Ling Tian narrowed his eyes upon hearing the woman's words. He had learned a few things from the waiter in the restaurant in Bloody Specter City. The levels of cultivation base are as followed; Heavenly Celestials, Golden Celestials, Great Overarching Golden Celestials, Overarching Heavenly Supreme Celestials, Celestial Dukes, and Celestial Kings.
"T-this Little World i-is actually left behind by a Superior Celestial King?" Duan Ling Tian's heart thumped wildly in his chest. Although his strength was comparable to a Golden Celestial, he was still essentially just a Crimson Moon Heavenly Celestial just like the newly-ascended cultivators. The reason why he had easily defeated many Celestials with a higher cultivation base was due to him being in a small town in the Spirit Overarching Heaven. Most of the Celestials in the small town only possessed Celestial Methods and Divine Abilities. Moreover, they only possessed primitive-level Celestial Weapons.
In the future, as he ventured out to bigger towns or cities, his advantage would gradually disappear. After all, the Celestials in bigger cities definitely possessed higher grades Celestial Methods, Divine Abilities, and Celestial Weapons.
'Eh? The jade token also contains information on how to pass the various difficult obstacles in the Little World. If both people act according to the instruction and stay together, they'll be able to pass easily and won't trigger the Yin and Yang Reversal Formation and Killing Formation!' Duan Ling Tian felt as though he had been given a guide just like the games he played during his spare time in his past life on earth.
'The various obstacles in the Little World aim to separate the two people instead of killing them. Without the information from this jade token, it's only natural that the man and woman would die since they're unaware that they aren't supposed to leave each other's side. Since I have the instruction, I don't think there's a problem with passing the obstacles.' Duan Ling Tian smiled. He should be able to successfully pass the obstacles with the woman next to him.
'There's a last message. If I'm not mistaken, it should be about the way to leave the Little World.' Duan Ling Tian was right. However, he did not expect the way to leave the Little World would leave him speechless. After passing the obstacles, in order to leave the Little World, the man and woman had to have sexual intercourse to open the exit of the Little World! Apart from that, after passing all the obstacles, if the man and woman did not have sex within three months since their arrival, they would also trigger the Yin and Yang Reversal Formation and the Killing Formation.
Duan Ling Tian was truly shocked. He quickly threw the jade token that was emitting a green light back to the woman as his hand trembled.
"Have you finished reading the message?" The woman asked.
Duan Ling Tian nodded.
The woman stared at Duan Ling Tian and said determinedly, "I-it's impossible f-for me to… to… to do that with you. I'd rather die!"
Duan Ling Tian frowned, "What do you mean? Do you think I'm willing to do that with you just to leave the Little World? Don't think too much! I, Duan Ling Tian, have wives and children after all. Even if I don't, I'm not into casual sex. You said you'd rather die than do that with me. Let me tell you, even if you want to do it with me, you'd still have to see if I'm willing!" He glared at the woman indignantly.
"You..." The woman was furious. She did not expect the man would launch into such a long tirade. However, based on his words, it was clear that he was different from other men. If it were another man, they would definitely not think like him. Although she rarely interacted with men, she was not unaware of their nature.
Duan Ling Tian glanced at the woman and said, "Alright! Let's just pass all the obstacles according to the instructions for now. After that, we'll try to find another way to leave." He could see that the woman with a veil was a peerless beauty like his two wives. In fact, her temperament might be better due to her profound cultivation base. However, he had no other intention with this woman. After all, two wives and a partner was more than enough for him.
