"Below the ancient city." Jade Whisk looked questioning.

"Now that spring has just begun, the trees on the small island in the lake should not be lush, unless it is isolated from the outside world, only the formation can isolate this area, that is to say, although the wall of this city has collapsed, but the formation is still there, since the formation is still there, the earth branch is naturally there, there is no on the surface, then it must be under the ancient city." Zuo Dengfeng explained.

"If the formation is still there, how can we see that small island." Yu Fu asked, she was good at using poison and driving femininity, but she was not proficient in formations.

"The invisible formation outside the ancient city of Lu where the giant is located is only one of the formations that evolved from the twelve solitary void methods, not all formations are invisible, the most subtle thing about the twelve chapters of the solitary void law is that the formations laid out are ever-changing, and there is no trace to be found." Zuo Dengfeng shook his head and said.

"What are we going to do now?" Yufu is not a person who has no ideas, but with Zuo Dengfeng, she willingly obeys Zuo Dengfeng's arrangement and follows his steps.

"Let's take a rest first, I can't hold it anymore." Zuo Dengfeng turned around and walked towards the city tower, the two of them had been in a hurry for the past two days, and they had not had a good rest, and the weight of more than three hundred catties made him extremely tired.

In ancient times, the city wall had a tower above the city gate, and the city tower was used for the soldiers who defended the city to shelter from the wind and rain, and there was also a city tower above this ancient city, but unlike the more than four city towers in an ordinary city, it only had a city tower in the south, which means that there was only one city gate in this ancient city.

The city tower is not big, there is no door left and right, the lookout mouth of the north and south is also breathable, but it is good not to worry about the invasion of poisonous insects, after the jade whisk put down the cover, the left peak sat down against the stone wall, the jade whisk sat on his right side, the two of them were each responsible for a lookout, the observation was not outside the city, but inside the city, although the earth branch was in the formation, but the poison derived from it was outside the formation, and had to be guarded.

Thirteen had been in charge of guarding the two of them while they were resting, and he was also extremely tired, and after entering the tower, he lay down on the blanket and began to nap.

"It's nearly six thousand miles from here to Bible Mountain, and it will take five days to arrive at the fastest with a clear and pure body, and it will take two days for the frogs to return, and we still have five days to deal with things here, so don't worry." Yufu saw Zuo Dengfeng's expression solemn after he sat down, and guessed that he was worried about possible changes in his hometown.

"I still want to go to the west side, I don't have enough time." Zuo Dengfeng sighed long, his time was not enough, and he was in trouble one after another, what he hoped for most now was that the green worm with the silver crown had nothing to do with him, but he also knew that this kind of possibility was not big, and blind self-comfort was tantamount to self-deception.

"It's too late, besides, even if Fujisaki really captures your family, he won't dare to do anything to them." Jade Fu spoke comfortingly.

"My surname is different from our Chinese, they can die in order to complete the task, when Fujisaki Sakurako can give up their original appearance, it can be seen how crazy they are, crazy people do everything, forget it, don't talk about this, you sleep well, I want to think about how to break the formation." Zuo Dengfeng shook his head and spoke, Zuo Dengfeng was not sure what the specific effect of the formation here was, but he could be sure that there must be a formation here, and the formation must be complete.

Yufu didn't speak again when she heard this, and she wouldn't bother Zuo Dengfeng when he was thinking about the question.

To break the formation, you must first know what kind of formation the formation is, to determine this, you must first check the clues remaining in this ancient city, in order to determine the reason for the demise of the Pu people, this is not closed, it stands to reason that the Pu people should not be extinct, so there must be a reason for their extinction, and if you find this reason, you can find the clues of the formation, that is to say, it seems to be a simple thing to break the formation, but in fact, it is necessary to investigate what happened before this ancient city.

First of all, one thing that can be determined is that there was no war here, otherwise the city wall and the buildings in the city would not have been so intact, and the west wall collapsed because the city wall was originally built up in water, and it is normal for it to collapse after being soaked in water for a long time.

Since there was no war here, there was another reason for the demise of the Pu people, and only through the search of the ancient city could the clues be found, thinking of this, Zuo Dengfeng stopped thinking, and closed his eyes to rest with his hands pinching the qi gathering fingers.

Night covers the land, and the ancient city is silent.

In the middle of the night, the two of them woke up, and the person who had survived the catastrophe had strong self-control, and could decide the general time of his wake-up before going to sleep, and a few hours of rest was enough for the two.

"Let's go into town." The jade whisk has finished tying the bedding.

"Don't worry, let's see what's in this lake." Zuo Dengfeng lifted the big wooden box, took out a few grenades from it and turned around along the city wall to the west, there are definitely things in the city, but there are no on the ground, then it can only be underground, it is better to scare them out than to close your eyes and be blind.

Coming to the gap in the city wall, Zuo Dengfeng tied five grenades together, pulled all the fuses, and used the aura to skim the grenades into the lake.

The grenade sank into the water immediately, and a moment later a loud noise was heard, and a huge splash appeared on the water.

After the water fell, the lake gradually calmed down, and the two of them waited intently for a long time, but did not see any animals floating up from the water.

"This lake is not within the scope of the formation's protection." Zuo Dengfeng shook his head and said, many of the water droplets splashed by the grenade explosion before fell around the two of them, which showed that there was nothing abnormal in this lake.

"This lake in the city is connected to the river, and once the Gu poison is cast, it will spread to the river." Yufu's face was solemn.

"You don't need to put Gu out." Zuo Dengfeng shook his head and said, before that, he had considered that the Gu poison of the Jade Whisk might not be suitable for use here, so he prepared diving equipment.

"The lake is so low that there's no way to drain the water out of it." Yufu shook his head slowly, it is the best choice not to go into the water, once the danger of going into the water will increase exponentially.

"Let's go to the city and check to find out how the people here went extinct in the first place." Zuo Dengfeng waved his hand at Thirteen, and Thirteen jumped on his shoulder.

The two of them turned back to the eastern side of the city, rubbing themselves down the city walls and entering the ancient city area.

Because the time is not sufficient, the two did not search in the ordinary house, but went straight through the city to the northeast area, the buildings in the east city are divided into three kinds, one is the low bluestone bungalow, this kind of house is mainly concentrated in the southeast area, accounting for seventy percent of the buildings in the city, and there is a slightly spacious stone house, this kind of house is mainly concentrated in the middle, accounting for two percent, the tallest building is the stone building, in the northeast of the city, there are only a few buildings, the two are going to these stone buildings.

The highest stone building in the northeast corner is three floors, the second and third floors are the buildings of the decorative surname, and can not live in people, the lower floor covers an area of more than two acres, the stone gate is two zhang high, the double fan is closed, according to the style of the stone building, this is not the place where the princes and monarchs live or the place where the city is discussed.

"Why are the houses in the city closed without exception?" When Zuo Dengfeng looked at the stone building, Yu Fu said.

"I don't know, I had a very bad feeling after entering the city, I didn't feel the danger, but I felt an indescribable palpitation." Zuo Dengfeng shook his head.

"I feel something similar, but I don't feel the presence of the Shadow either." Yufu's face was solemn.

Hearing this, Zuo Dengfeng looked at Thirteen and found that Thirteen's right eye had not changed color, which meant that it had not found anything abnormal.

"Let's go in and have a look." Zuo Dengfeng thought for a while and said, it was no longer necessary to make useless guesses when he had already arrived at the door, because the answer was inside the door.

Hearing this, Jade Whisk nodded in agreement.

Seeing this, Zuo Dengfeng stepped up the steps, there are seven steps in front of this stone building, the multiple of nine was used by the emperor in ancient times, eight was the number of kun, which was dedicated to the royal concubines, seven was the princes, the chariots used by the princes, bronze, musical instruments and other things were all multiples of seven, and there were seven steps at the entrance of the highest building in the city indicating that this was the location of the vassal state, but the Pu State was only a tribe before following Jiang Ziya's eastward expedition, and they were only awarded the title of princes after the establishment of the Zhou Dynasty. In this way, these seven steps indirectly show that this city was built or rebuilt after the Pu State was crowned a prince.

The terrain here is remote, the civilization is not developed, and the yin and yang gossip is easy to count, and the people here are unlikely to be proficient in these, so this city may have been built or rebuilt under the guidance of a master, and this person is very likely to be Jiang Ziya.

Zuo Dengfeng pondered and walked up the steps to the door, and found that this gate was a double-leaf inner open door, two zhang high, and one zhang on the left and right doors, the door may have been carved with patterns before, but at this moment it has been worn away by the years, and the bluestone has also shown a long-standing pale after being exposed to the sun and rain.

The left peak probe pushed to the right stone door, and after a try, he did not move at all, and tried again, but it was still the same.

"I can now extend my aura to move a thousand catties of heavy objects, this stone gate definitely does not have a thousand catties, and it may be blocked inside." Zuo Dengfeng looked back at the jade whisk.

"Together." Hearing this, Yufu stepped forward and pushed the stone gate with Zuo Dengfeng, but the two of them couldn't push it together.

"What are they guarding against?" Jade Whisk withdrew his aura and looked puzzled, according to the current situation, the stone gate must have been resisted inside, and the large and small houses in the city were closed, which showed that they were guarding against something before.

"Something they feared, but it didn't come, for the buildings in the city showed no signs of battle, other than the weathering of time." Zuo Dengfeng shook his head and said.

"They already knew that something that could hurt them was coming, and you can see that all the gates in this city are closed, which shows that they are well prepared." Yufu said.

"It's better this way, everything can be preserved well." Zuo Dengfeng nodded and said, if it is outside or with the door open, it is difficult to preserve the things from three thousand years ago, but the doors here are closed, and the houses have no windows, so the things inside can be well preserved.

"What now?" Jade Whisk asked.

"Change to a smaller room and see the situation first." Zuo Dengfeng turned around and walked south, followed by Jade Whisk and Thirteen.

After a while, Zuo Dengfeng and Yufu came to the outside of a flat-roofed stone house, this stone house is much smaller than the previous one, Zuo Dengfeng pushed his hand to the stone door, and found that the inside was also resisted, and the stone door was shaken open by condensing force, and the stone door was opened, and the scene in the house was unobstructed, and Zuo Dengfeng first saw that there were people in the house!
