"His bad luck was doomed." Yu Fu said with a smile.

Zuo Dengfeng nodded when he heard this, just as Yufu said, Fujisaki's bad luck was doomed, from the moment he broke into the Qingshui Temple, he was already a dead man, because he provoked people who shouldn't be messed with.

"I hope it's derived from the Yang Earthly Branch, otherwise it will be difficult for us to deal with the flying poison." Yufu put away her smile and said.

"Weiyang's guardian poison is a poisonous python, which has been killed by Du Zhenren, and there are three local branches, and only one-third of the surnames we encountered." Zuo Dengfeng carried the wooden box on his back.

"Didn't Thirteen fight with them back then, you can ask Thirteen." Jade Whisk suddenly thought of something.

Zuo Dengfeng suddenly realized that Thirteen was the "party" of the year, and it should know the situation of the year.

"Thirteen, were there twelve poisons involved in the battle with the twelve earthly branches back then?" Zuo Dengfeng looked down at Thirteen who were standing beside him.

Thirteen looked at Zuo Dengfeng with a puzzled face, without shaking his head or nodding.

"What's wrong with it?" Jade Fu asked.

"Thirteen doesn't have a good understanding of numbers, and it starts to get confused when it goes beyond two digits, and the question I'm asking is too complicated for it to understand." Zuo Dengfeng shook his head and said, among animals, Thirteen's IQ is already very high, but it is not a human after all.

"Changing the subject." Jade Whisk laughed.

"Thirteen, will the dragon's companions in the earth branch fly?" Zuo Dengfeng thought for a while and asked.

Thirteen shook his head.

Zuo Dengfeng and Yufu glanced at each other, both frowning.

"The dog's companion will not fly." Zuo Dengfeng asked again.

Thirteen shook his head again.

Seeing this, Zuo Dengfeng and Yufu frowned again, and the two Yang surnamed earth branches were all ruled out.

"The cow's companion will not fly." Zuo Dengfeng hesitated for a moment and asked again.

Thirteen nodded.

Seeing this, the two of them immediately smiled bitterly and shook their heads, this difficult poisonous bird was derived from the Yin Earth Ox they were looking for.

"Pigs have no partners." Zuo Dengfeng asked again, the reason why he used the word partner was because the earthly branch and the poison were not friends, but the relationship between control and control.

Thirteen shook his head.

"I'm right, Jiang Ziya did forcibly take away the water yin pig back then, and the poison of the water yin pig was indeed killed, and it didn't participate in the fight." Zuo Dengfeng turned his head to look at the jade whisk.

Hearing this, Yufu nodded, and turned to put on the futon on her back.

Seeing this, Zuo Dengfeng glanced at Thirteen, the latter jumped on his shoulder, Zuo Dengfeng took the lead in sweeping north, and Yufu bent his knees and followed like a shadow.

"I always felt like something was wrong." After sweeping ten miles, Zuo Dengfeng looked back at the ancient city behind him.

"What's the problem?" The jade whisk moved sideways in mid-air and approached the left peak.

"I don't know, anyway, I feel like there's something we've overlooked." Zuo Dengfeng landed on the ground and did not volley again.

Yufu didn't have an interface when he heard this, but fell to the side and quietly looked at Zuo Dengfeng to think.

"You said that the water is a poison derived from the Yin Pig, where did you live back then?" Zuo Dengfeng groaned for a long time and frowned.

"The east side of the ancient city is where humans live, and the west side is where merfolk live, and the water pig lives in the waterhole on the east side, and the poison derived from it may live with mermaids." Yufu speculated.

"Why didn't it attack those merfolk?" Zuo Dengfeng frowned and asked again.

Yufu didn't answer when she heard this, and she couldn't answer this question, or even guess.

"Merfolk are low-status slaves in the Pu Kingdom, and they have every chance to escape when they go out to fight, so why don't they escape." Zuo Dengfeng asked questions again without waiting for Yufu to answer, and his questions were not only about Yufu, but also about himself.

Jade Whisk still didn't speak, those merfolk were attacking each other in the water, they needed to be flexible, and they definitely couldn't be tied with ropes, which means that they were completely free when fighting, why didn't they escape.

"When I was attacked in the lake, they attacked very regularly, and they didn't rush up, which shows that something is directing them, and who is directing them." Zuo Dengfeng stretched his hand and stroked his forehead and thought hard.

Yufu shook her head and smiled bitterly when she heard this, she couldn't answer Zuo Dengfeng's question, and with Zuo Dengfeng, she found that she was not as smart as she thought she was before.

"Hahaha." After a moment, Zuo Dengfeng laughed loudly.

Seeing this, Yufu was happy for him from the bottom of her heart, she knew that Zuo Dengfeng had figured it out, although she didn't know what Zuo Dengfeng had figured it out.

"The poison derived from the earth branch is the leader of the mermaid, and the poison leads them during the battle, although it is the poison leader fish, but to put it bluntly, it is the water Yin pig leader fish, so the poison is controlled by the earth branch." Zuo Dengfeng said with a smile.

"You have a point." Yufu cleverly reminded Zuo Dengfeng that he needed evidence to prove his inference.

"The Jiuyang monkey is trapped, the golden rooster is trapped, but the water yin pig here is not only not trapped, but also enjoys a high treatment, the tribesmen will feed it, and even throw the jewelry into the waterhole, this is a kind of worship and gratitude from the heart, why do the Pu people worship this water yin pig, the water belongs to the earth branch to them is only one of them, and the second is that the water yin pig can control the poison leader fish." Zuo Dengfeng explained.

"Makes sense." Jade Whisk nodded again.

"Let me ask you a question, under whose guidance the ancient city was built." Zuo Dengfeng induces Yufu to move towards the truth.

"The master of Thirteen." Jade Fu replied.

"Is the master of Thirteen powerful?" Zuo Dengfeng asked again.

"Knowingly asked." Yufu glanced sideways at Zuo Dengfeng.

"Such a powerful person, the city wall under his guidance must be very strong, he will not fail to consider that the west wall will be soaked in water for a long time, so in the early stage of construction, he will definitely find a way to strengthen it for a thousand years to be complete, but why did such a city wall collapse." Zuo Dengfeng asked again.

"No matter how strong the walls are, they will collapse one day if they are soaked in water." Jade Fu shook her head and said.

"Okay, the most critical question is here, the people here were poisoned together, when the city walls were intact, and the mermaids were not fed, why didn't they starve to death." Zuo Dengfeng looked at Yufu with a smile.

Hearing this, Yufu suddenly frowned, the lake area in the city is not large, even if there are fish in it, it is not enough to feed those mermaids, the city wall is two zhang wide and completely made of bluestone, this kind of city wall mermaid can never be destroyed before starving to death, Zuo Dengfeng's question is very sharp, why were the mermaids not starved to death.

"Will there be a waterway under the water to the outside world?" Jade Whisk guessed.

"Impossible, it must be completely closed, otherwise Yin and Yang will not be balanced, and the feng shui of Yin and Yang City will be finished." Zuo Dengfeng shook his head and smiled.

"Why didn't they starve to death?" Yufu directly admits defeat and asks for answers.

"Because something broke the walls and saved them before they starved to death." Left to climb the peak of the positive color opening.

"There are a large number of poisonous surnames left here, and even poisonous insects dare not enter within a hundred miles, unless the owner of Thirteen has released the mermaids here." Jade Whisk nodded and said.

"What you said seems to be very reasonable on the surface, but you ignore an important point, since the original master of the Thirteen Provinces sealed the souls of the people of Pu Kingdom, he naturally wanted to save them, the reason why he didn't save it was because he couldn't save it at that time, since he couldn't save it at that time, what did he do by sealing the souls of these people, after a long time, the organs would rot, why did he do such a futile thing." Zuo Dengfeng's thoughts were unusually clear.

"Why?" All Jade Whisk can do is be a good listener.

"Because the ancient city of yin and yang is in a delicate state of yin and yang peace after all the earthly branches and poisons have left, this state can keep the dead here relatively still, so as to leave him a certain amount of time to find a way to save people, if he thinks that he can't save people, he won't work in vain, in such a situation he won't touch anything in this city, won't destroy the city wall, and won't let go of the mermaid, and there will be someone else who breaks the city wall and releases the mermaid." Zuo Dengfeng shook his head and said.

"The Water Yin Pig is back,." Yufu finally understood what Zuo Dengfeng wanted to express.

"Yes, only it can be free from the poison emitted after the death of the poison, only it will care about the life and death of the mermaid, and only it has the ability to demolish the city wall, you must know that the city wall is too heavy, it must be demolished from above, otherwise it will not be demolished at all, and it happens to have the same huge fingers as a human to do this job." Zuo Dengfeng turned his head to look at the eastern sky, and the sky was already bright.

"Let's go, go back." Yufu suddenly realized.

"This pig has a very high IQ, and he has been hiding and not showing up, we can't force it, we can only outwit, otherwise that guy may run into the Lancang River." Zuo Dengfeng didn't go fast.

Hearing this, Yufu walked a few steps quickly to keep up with Zuo Dengfeng, and walked side by side with him.

"After the defeat against the thirteenth, the water yin pig was let go by Jiang Ziya, and it returned here against the water, it has been living here, and it will naturally come back, because animals have the instinct to return to the nest." Zuo Dengfeng explained.

"The Lancang River flows to foreign countries." Jade Fu shook her head and said.

"The Jinsha River is not far from here." Zuo Dengfeng waved his hand and said.

"Why doesn't it stay in the waterhole on the east side." Yu Fu was already convinced that Zuo Dengfeng's analysis was correct at this moment, and she only had doubts in her heart when she asked.

"The tribesmen are dead, it has no one to feed, what to eat there, and besides, it has lost the protection of poison, and it is relatively safe to stay with the mermaids." Zuo Dengfeng shook his head and said.

"Its painstaking return has disrupted the balance of Yin Yang City and killed those people." Yufu sighed and spoke, women have sympathy, and she was very moved by the scene of an animal thousands of miles away from her hometown returning to her hometown with great difficulty.

"The original owner of the Thirteen is usually dead, otherwise, even if he can't save the people of Pu Kingdom, he will come back and let go of their souls." Zuo Dengfeng was thinking about another thing, he didn't sympathize with the enemy, he was almost stabbed to death by those merfolk under the water before.

"What's next?" Jade Fu nodded and asked.

"These animals will have the habit of going ashore to bask in the sun, and go back to hide and act as an opportunity......"
