Ling'er said, pointing her little finger at her feet.

"You said underground?" Lan Jiao rolled his eyes and said, "Ling'er, do you want to dig up the entire Kailin City inch by inch?"

"Digging in the ground is naturally unrealistic. Su Ping'an chuckled and said, "That efficiency is too slow, and the movement is too big, it won't be good to attract disciples from the Seven Nights Palace." ”

Su Ping'an also felt that the most likely place for the treasure of the Lu Xueyao family to exist was under the Kailin City, and only in the underground of the Kailin City would the treasure never be discovered.

"What should I do then?" Lan Jiao asked as he touched his head with his paws.

Su Ping'an showed a sly smile and said, "Lan Jiao, you are a demon clan, this art of retreat should not be difficult for you, right? ”

"Su Ping'an, what are you kidding? I'm a Jiao clan with noble blood!" Hearing that Su Ping'an was going to make a hole by himself, Lan Jiao said indignantly, "This kind of thing is something that snakes, insects, rats and ants can only do." I'm a dignified Jiao clan, and I'm also a blue Jiao with noble blood, how can I do such a shameful thing?"

"When I go back, I'm in Kailincheng Restaurant, and I have someone prepare a roast whole beef for you. Su Ping'an chuckled.

Lan Jiao swallowed a mouthful of saliva, looked at Su Ping'an and said, "This is not a matter of roasting a whole cow, this matter is related to the dignity of my Jiao clan......

"Both ends. Su Ping'an said again.

"I said this thing is not about roasting whole beef, how can you ......"

"Four-headed. ”

Su Ping'an threatened again, "Lan Jiao, if you don't go today, you won't even want to eat a roasted whole cow this month." ”

"Ridiculous, do you think that you can tempt me and threaten me with a few roasted whole cows? Let me tell you, Su Ping'an, I helped you because the two of us are friends, not because of any roasted whole beef. Lan Jiao continued, "I'm going to investigate the underground of Kailin City, you remember to prepare five roasted whole cows in the restaurant in advance, and I will eat them after I come back from the underground of Kailin City." ”

"Don't worry, Lan Jiao, if you really find anything in the underground of Kailin City, don't say five roasted whole cows, ten roasted whole cows, I will have people roast you. Su Ping'an chuckled.

Hearing Su Ping'an's promise, Lan Jiao nodded with satisfaction, and then it transformed, and its body turned into a small blue snake more than a foot long and the thickness of a thumb. The little snake wagged its little tail and instantly escaped into the ground, leaving only a small hole the thickness of a thumb.

After Lan Jiao escaped into the ground, he began to search quickly within the Kailin City. Any rocks and other obstacles along the way were smashed by it, and the crawling speed was extremely fast. It can be seen that the head of this blue Jiao thief iron.

It only took an hour for Lan Jiao to search the ground, but he found nothing. Lan Jiao thought about it, then retreated into the four zhang, and began to search within the range of eight zhang deep underground, but still found nothing.

Lan Jiao retreated down again into the four zhang, came to the area twelve zhang deep underground, and began to search. Suddenly, after searching for a place in the underground of Kailin City, all the rocks and dirt around Lan Jiao disappeared at once, and he appeared in a mysterious space.

Twelve zhang deep in the ground of Kailin City, there is such a mysterious space hidden! Could it be that the treasure that Lu Xueyao said is here?

Lan Jiao's body returned to the size of an adult, and it flew to the ground, looking at this mysterious space. This is a mysterious space with a height of four zhang and a length and width of more than ten zhang. Because it is located in the underground of Kailin City, which is twelve zhang deep, this mysterious space has no light, and it is pitch black. Fortunately, the Jiao clan's night vision ability is very strong, and the blue Jiao can also see the environment around this mysterious space.

The top of this mysterious space is made up of a pale yellow rock, and the feet and four walls are made of golden stone slabs with mysterious runes inscribed on them. The entire mysterious space gave Lan Jiao a very uncomfortable feeling, as if there was still some mysterious aura oozing from under his feet.

"No matter, I'll go out first to inform Su Ping'an, and let Su Ping'an come down to investigate in person. This mysterious space must be worth at least nine roasted whole cows, right?"

With that, the blue dragon turned into a small blue snake again, returned straight up to the surface, and appeared in a large hall.

"Feng Fengzong, it's actually here!"

Lan Jiao said secretly in his heart, then turned around and left Feng Fengzong and rushed to report to Su Ping'an.

This Feng Sect can only barely be regarded as a non-mainstream sect, there are only more than ten monks in the sect, and the strongest of them is only a monk in the early stage of foundation building, and it is only a foundation building double cultivation.

Perhaps it was precisely because of the weakness of the Feng Feng Sect that the Seven Nights Hall would allow the Feng Feng Sect to exist in Kailin City. In the eyes of the Seven Nights Palace, Feng Feng Sect said that it was a sect, but in fact, its strength was weaker than that of some monk families.

After a stick of incense, Su Ping'an, Lu Xueyao, Ling'er, and Lan Jiao came to the sky, directly through the closed gate of Feng Fengzong, and came to the main hall.

Su Ping'an's eyes kept looking at Feng Feng Sect, and the mysterious space that Lan Jiao said was directly below the main hall of Feng Feng Sect, I don't know if there was any coincidence. That mysterious space, I don't know if there is any connection with Feng Feng Sect.

However, that mysterious space was completely sealed in the depths of the underground of Kailin City, and there was no passage to connect it to the Fengfeng Sect. This should show that the monks of the Fengfeng Sect are most likely unaware of the existence of the mysterious space underground.

The arrival of the four foundation building period monks disrupted the peace of the Fengfeng Sect, and Du Buping, the sect leader of the Fengfeng Sect, personally greeted him.

"Dare to ask the four Taoist friends to visit suddenly, I don't know what to do. Feng Feng Sect Sect Master Du Buping asked.

The other monks of the Feng Feng Sect were all standing behind Sect Master Du Buping, and most of them had fearful expressions on their faces.

Su Ping'an wanted to test whether this Fengfeng Sect Sect Master knew about the existence of a mysterious space deep underground, so he replied indifferently: "We are here for the things below. ”

"What's next?" Fengfeng Sect Master's face was dazed, not knowing what Su Ping'an was talking about, he asked, "Can Daoist friends be more specific?"

Su Ping'an saw that the expression on the face of the Sect Master of Fengfeng Sect did not look like a fake, so he glanced at the blue Jiao beside him.

Lan Jiao took a step forward, with a hideous expression on his face, and said, "We have requisitioned several halls of this Feng Sect, you guys get out of here quickly!." ”

As soon as Lan Jiao finished speaking, the Fengfeng Sect monks in the main hall were in an uproar.

Feng Feng Sect Sect Master Du Buping hurriedly said with a nervous expression: "This fellow Daoist, my Feng Feng Sect has been here for more than two thousand years, and the history is even older than this Kailin City. Daoist friends suddenly let us leave today for no reason, is it too much of a deception?"
