There were 26 doors around the piazza.

Li Mu muttered, “What do these mean? Are we asked to choose one from the 26 doors? And then can we get out with the right choice or will we die with the wrong choice?”

“It should mean that.” Mrs. Hong said, “The possibility to choose the right door is one twenty-sixth. It's not much better than being doomed to die.”

With slight wounds, Lin Kun went to check those doors alone. After revising some doors, he said suddenly, “Look here. There are differences between latches!”

Mrs. Hong told Lin Wan, “Please stay here to look after Xiaoyu. Li Mu, we come to see the latches!”

They hurried to Lin Kun and Mrs. Hong asked, “Lin Kun, what do you find?”

Lin Kun flicked his finger towards the latches, “Mrs. Hong, there are two kinds of symbols carved on the latches.”

Mrs. Hong looked down. As it turned out there were differences between doors though they looked the same from a long distance. There was a symbol at every latch. If you couldn't approach to revise the latches, you would never find this difference.

Three people circled the piazza to revise the symbol. Lin Kun was right. There were in total two kinds of symbols. Some latches were carved with the pentagram while others were carved with the triangle.

Mrs. Hong scoffed, “I got it. This is the divinatory symbol. We can figure out the door of life by the divinatory symbol.”

Li Mu didn't understand. He asked, “Divinatory symbol? Is that Yin and Yang and Bagua? That should be 8 doors with doors of life and doors of death. How can you explain the 26 doors?”

“Grand Terminus produced the two elementary Forms. Those two Forms produced the four emblematic Symbols, which again produced the Bagua. The Bagua served to determine the good and evil essence of events. And from this determination was produced the successful prosecution of the great business of life. Sixty-four trigrams were produced by the foundation of a series of Bagua. These 26 doors respectively represent Yin and Yang. But I can't figure out the secret behind the other two doors.”

Li Mu didn't understand this and Mrs. Hong didn't explain too much. After remembering the turns of symbols, Mrs. Hong returned to Lin Wan to discuss the divinatory symbol. Lin Kun followed to listen. Only Little Brother Li strayed on the piazza.

Li Mu searched details on those doors over and over again to find other differences. He searched for a long time but gained nothing.

The buzzing of the sandy hourglass continued. But Mrs. Hong and others didn't figure it out. The sensation tightened everyone's heart. And their faces grew grim.

“We should choose one of the doors!” Li Mu pondered, “But there are not many differences between those doors. Which one should we choose?”

With hesitation in his heart, Li Mu circled the doors over and over again and didn't know which one to choose.

Gradually, he frowned and his throat tightened. He became more and more anxious.

He just thought every door was an alternative while every door was forbidden. He wanted to push this door but he felt this door wasn't the right one. And then when he wanted to push another one, he thought the previous door would be better.

He struggled to try but always ended with a flinch. The nerve overwhelmed him. For a long time, Li Mu just circled the piazza over and over again and no choice could be made.

The argument grew louder and louder. Lin Wan and others couldn't reach a unanimous conclusion. Everyone's heart sank with the worry about how to escape from the dead end.

Li Mu was extremely worried. Nervous sweat trickled down his cheeks. Suddenly a subliminal hint flashed across his head. He hurriedly turned to his friends' faces and then touched his own face. Everyone's face was almost the same as the worried face of the statue.

The hint became clear in his mind. He scolded, “F*ck, I got it. Worry. The heart realm of this mechanic system is worry. These fart-sucking people! Do they want to lead me to death by decidophobia?”

His voice startled the other three people gathering far away from him. Lin Wan was worried, “Honey, what's wrong?”

Li Mu shook his hands to stop their voices and continued his thought.

Sometimes people got worried. When they should make decisions, they always flinched with lots of worried and then hesitated to make the final decision.

Li Mu knew he himself seemed to have this trouble. Prolonged worry destroyed his gut to make a decision. And then he flinched because of his worries. Eventually he never dared to face his worries.

He was trapped by worries. How about Lin Wan? She was, too. And the worries also trapped Mrs. Hong and Lin Kun, just more or less.

It seemed the designer of the piazza wanted to take advantage of the human's weakness to conquer the intruders. Which was to say, the designer of the piazza wanted to take advantage of seven different heart realms to make the intruders lose their minds and lives.

Figured out this, Li Mu snorted contemptuously, turning his face to Lin Wan, “Honey, do you believe in me?”

“Yes, of course.” Lin Wan answered without any hesitation.

“How about you? Do you believe in me?” Li Mu continued.

Mrs. Hong and Lin Kun nodded together. Li Mu walked with a sly grin and shouldered He Xiaoyu. Then he said to others, “Keep silent and follow me!”

After these words, he turned his heel. The other three people followed him tightly without a word.

Li Mu randomly chose one door and opened it. With a stronger drag from his arm, the door was pulled off. Li Mu left one hand to hold the door and another to shoulder He Xiaoyu. He walked out decisively. And others followed.

The way they walked burst into white glory. When the glory faded, they all returned to the corridor. And the stone doors closed slowly behind them. The two sisters jumped with tears dropping down their cheeks. They hugged Li Mu to cry loudly.

Then Mrs. Hong understood and clapped, “I know. Those symbols are left by the Shen Family to mislead intruders. Any door can be safe. In short, people who died here are people who struck themselves to death!”

Lin Wan comforted the two sisters and then whispered to Li Mu, “Why do you pull off the door? What does it mean?”

Noticing their gazes, Li Mu got embarrassed, “You always think too much. There is no other meaning of the door. I pull off the door to make the splints. Xiaoyu and Lin Kun need splints to fix their broken bones. That's it.”

Mrs. Hong laughed sweetly and got the door from Li Mu then reminded others, “This mechanic system was destroyed by Li Mu totally. Only if the intruder wasn't an idiot, he would know where to leave.”

“Yes. With such a clear entrance, if anyone still doesn't know, then he deserves death!” Li Mu said in triumph.

Suddenly he thought about something else and then asked others, “We must leave here and stay away from the piazza. The farther we keep from the piazza, the safer we are!”

Before all things were totally figured out, nobody dared to come into the hole. What they could do was running away from the piazza. After they ran away from the piazza, they could be in relief. And then they made three splints for He Xiaoyu and Lin Kun to fix the broken bones.

He Xiaoyu was still in deep sleep. Lin Wan fed her some water and groaned, “Xiaoyu and Lin Kun are wounded. What should we do next?”

Shen Zixing sobbed, “It's our fault. It’s us that lead Sister Xiaoyu into this condition!”

Li Mu rubbed her hair and comfort her, “Nonsense. It's not your fault. Anyone who explored the statues will result in this. We must overcome this mechanic system. No shortcut can be used.”

“Actually, there are great differences.” Mrs. Hong added.

“Ah, what difference do you think there are?” Li Mu asked.

“Letting the sisters explore the statue is the rightest choice. If others do that, he would face the mechanic system himself. It will be more dangerous.”

People didn't understand. Mrs. Hong explained, “The two sisters belong to the Shen Family. Their destruction of the statue cast results on others. So we were dragged into the mechanic system. If we touched alone, it would cast results on us respectively. And then we must face the mechanic system alone. It wouldn't be easy to pass.”

Now people understood. Lin Kun asked, “Mrs. Hong, must we overcome all the heart realms one by one and then we can leave here safely?”

“Yes. This is the second advantage of letting the two sisters destruct the statue. After they triggered the mechanic system, we can overcome these seven heart realms together. Or we would overcome these seven heart realms one by one. I can hardly believe we can all pass.”

Lin Wan had remained silent for a while. She asked Mrs. Hong now, “Mrs. Hong, we have found the hole. We can just leave there without going through the heart realms!”

Mrs. Hong shook her head.

“It certainly can't work. Except for the sisters, others must pass the heart realms and then they can leave safely. If we took the shortcut, maybe there will be more dangers.”

Li Mu frowned, “Xiaoyu and Lin Kun are wounded, especially Xiaoyu. How can she continue to go through the heart realms with so serious wounds?”

Lin Wan comfort him, “Honey, don't worry. We can figure a way out!”

Li Mu looked at He Xiaoyu deeply and complicatedly.

“Wake her up first. She can't sleep anymore. I worry that too much sleep will close her eyes forever.”

Lin Wan woke He Xiaoyu up and helped her to sit and lay in her embrace.

Li Mu sighed and told Lin Wan, “Don't get yourself too tired. You are pregnant and need to act carefully. That strength of dragging is powerful. I’m worried that...”

“I know. But there is no other way. All people must pass the heart realms unless they died.”

Death. Li Mu's eyes dazzled while he muttered this word.

Mrs. Hong asked at his side, “Li Mu, do you have any good idea?”'

'Mrs. Hong, how long will someone be dangerous if he or she faints?'

“It depends on the spirits. The more powerful spirit someone has, the more quickly someone would wake. Take Xiaoyu as an example, others might sleep to death and never wake. But she just has a sleep.”

“Which is to say, I don't need to prick her and Xiaoyu will wake up herself!”

“Yes! That's it!”

He Xiaoyu shook her fingers and said in an injured tone, “Li Mu, I'm still painful.”

People all laughed. The nerves and stress were relieved much.

“Li Mu, you haven’t answered me. Do you come up with some brilliant ideas?”

“False death!”

“False death?”

“Yes. We pretend to be dead. And then the sisters could take us out!”

“That is a way. And the hole leads to the outside place. We pretend to be dead bodies. And then the sisters would take us out. I think it can work. Lin Wan, what do you think?”

Lin Wan pondered for a while and nodded, “I think it can work too. Let's do it!”

“Lin Kun should be the first!” Mrs. Hong suggested, “We need to make sure there is no danger at the exit of the hole. Let Lin Kun check there.”
