After two months of non-stop spying on intelligence, Zhang Yifan found several crocodile gang rudders, and then used his elusive light skills to obtain several crocodile gang rudder account books.

Through these account books, Zhang Yifan probably figured out some of the things that the Crocodile Gang was secretly doing, but these account books were far from enough to bring down the Crocodile Gang.

Luckily, he found some clues from one of the account books that the Crocodile Gang was selling illicit salt in Lingzhou. This made Zhang Yifan a little happy and decided to go to Lingzhou to collect evidence.

In addition, Zhang Yifan has another purpose, he is going to find that Lingzhou Fang City, increase his knowledge, lay some foundation for cultivating immortals in the future, and also purchase some necessary things.

Ever since he got Su Tianjue's Immortal Cultivation Miscellaneous Notes, he knew from the miscellaneous records that there was an Immortal Cultivation Market somewhere in Lingzhou, which specialized in selling related items needed by Qi Refining Period cultivators, and he had never been to that Fang Market.

The reason for this was that his strength was really weak at that time, and he was only a fourth-level cultivator in the Qi refining period, and secondly, he had been busy and had no time to check. This time, taking the opportunity to go to Lingzhou to investigate intelligence, Zhang Yifan was going to go to that Fang City to take a look.

Of course, the main reason why Zhang Yifan could muster up the courage to go to that Cultivating Immortal Fang City was because Zhang Yifan had advanced not long ago and reached the sixth level of the Qi Refining Period.

Zhang Yifan's Fire Flame Recipe has been cultivated to the sixth layer, which is also the last layer that can be learned at present. He was going to go to Xiuxianfang City to buy the whole book of the Fire Flame Technique.

Speaking of promotion, Zhang Yifan was also a little surprised, originally he thought that it would take a while to cultivate to the sixth layer of the Qi Refining Period.

Relying on the cultivation of the six Zengyuan Pills after continuous swallowing and refining, Zhang Yifan's mana cultivation was very fast, and he cultivated to the realm of the fifth layer of the Qi Refining Period in just one month.

But then, I don't know if the effect of the pill was weak, or if he developed the legendary resistance, the effect of the Zengyuan Pill on his cultivation became very weak.

Zhang Yifan returned to his previous turtle-like cultivation state, which made him a little crazy.

As a last resort, Zhang Yifan took the refined Great Returning Pill, but he didn't expect that the cultivation effect of the Great Returning Pill was much better than that of the Zengyuan Pill, with the help of ten refined Great Returning Pills, Zhang Yifan broke through the bottleneck of the fifth layer in one fell swoop in less than a month, and cultivated to the sixth layer of the Qi Refining Period.

Zhang Yifan was also very curious about why Da Huan Dan was so huge about mana cultivation, and after analysis, he could barely find a reason that made sense.

Da Huan Dan itself belongs to the best internal strength elixir, and there is no erysipelas, and there is no step of removing impurities after the mysterious well water refinement, so the mysterious well water has all strengthened the medicinal effect of Da Huan Dan, which should lead to a very obvious refining effect.

Zeng Yuandan is invalid, the Great Return Pill is exhausted, Zhang Yifan has no pills in his hands that are suitable for the current realm, and this time he went to Lingzhou Fang City to find out if there are suitable pills and pills.

After advancing to the sixth layer of the Qi Refining Period, Zhang Yifan's mana has improved a lot compared to before, and his whole temperament has become more and more dusty.

At the same time, I also began to have some understanding of the application of mana, and the spell has improved a little compared to two months ago.

Now that he has some eyebrows in his cultivation of the Golden Blade Technique, the golden blade issued is more than a foot long, and he can barely hit it. The power of the Golden Blade Technique did not disappoint him, even if it was fur, he could cut gold and break iron, and his steel heavy mace could not resist the two Golden Blades.

At the same time, Zhang Yifan's fire bomb technique has made obvious progress, the condensed fireball is the size of a bowl, and the casting speed is twice as fast as before, which is more powerful and faster than Su Tianjue's fire bomb technique at the beginning, and the speed is also faster, which can be used against the enemy.

In addition, to Zhang Yifan's delight, he now actually found a trick to cast the Wood Binding Spell, and in time he could cast it against the enemy.

Wood Bind is a wood-based spell, as the name suggests, it is a trapping spell that uses a spell to summon a branch of a tree to entangle and bind the enemy, restricting their movement.

......

Zhongnancheng is a medium-sized city in the south of Lingzhou, with a population of nearly one million, although the city is not large, but it is one of the wealthiest cities in Lingzhou.

As for the reason, the people in Zhong Nancheng basically mention Zhong Nanshan, and they are quite proud.

Zhongnan Mountain is the source of the Lingshan Mountain Range, and it is also the highest of the many main peaks of the Lingshan Mountain, according to the locals, it is thousands of zhang high, but no one knows the specific height.

The high part of the mountain is perennially covered with snow all year round. There is a large area of wild tea trees on the shade side of the mountain, and the snow on the mountain turns into a mountain spring, which makes the wild tea trees grow extremely vigorously.

The tea made by the local people from wild tea trees is the best of the tea leaves, and it is designated as a tribute to the emperor of Chu. It is precisely because of this wild tea tree that the local tea industry is very vigorous.

At the same time, Zhong Nanshan also produces some special ice spirit mountain fruits, mountain goods, and ores, which make Zhong Nancheng, who relies on the mountains and eats the mountains, rich and popular.

At this time, Zhang Yifan was in a teahouse in Zhongnan City called 'Mountain Tea House' to taste the local unique Zhongyin mountain tea, and asked some questions while tasting tea.

"Little second brother, do you know that there is a place called Zhong Nangu near here?" In the miscellaneous records of cultivating immortals, it is only roughly recorded that the fang market is a place called Zhong Nangu near Zhong Nan City, and the detailed location is not described, so Zhang Yifan had no choice but to inquire about the news in the nearby Zhong Nan City.

"This son, Zhong Nanshan knows it, but Zhong Nangu has never heard of it. Cha Xiaoer shook his head, obviously not knowing much about this place.

"Isn't there a place called Zhong Nangu?"

"It's not necessarily nothing, the little one has just come here, and he doesn't know much about the geography of Zhongnan City. Wait a minute, I'll find someone, you can ask him. Cha Xiaoer replied with some embarrassment, and then left.

After a while, Cha Xiaoer pulled an elder in his fifties to Zhang Yifan.

"This son, this is the shopkeeper Wu of our teahouse, a native of Zhongnan City, what can you ask him about the old man. Xiao Er introduced the old man next to Zhang Yifan.

"Hehe, the little second brother has a heart. Shopkeeper Wu, then bother, have you heard of Zhong Nangu?"

"Ahem, this boy is the right person. The old man happened to know the old name of that place. Shopkeeper Wu seemed to be in poor health, and replied slowly.

"Old man, please sit down, I would like to hear the details. Zhang Yifan's spirit was shocked.

Hearing this, the shopkeeper Wu sat opposite Zhang Yifan without shirking his words, and the tea Xiaoer on the side was also more interested because there were few guests in the morning, so he was also more interested and waited on the side.

"The Zhongnan Valley that Gongzi said was said a long time ago, and it was originally a valley more than ten miles away from Zhongnan Mountain. It's just that later, for some reason, a waterfall appeared in the valley, and the perennial fog was thick, and the valley disappeared, and over time, the locals changed its name to Zhongnan Mountain Stream. ”

"Thank you Shopkeeper Wu, do you know where this Zhongnan Mountain Stream is?" Zhang Yifan was happy, he guessed that this place was very likely to be the location of the Fang City.

"Childe, I know, I know, this Zhongnan Mountain Stream is at the foot of Zhongshan Mountain, more than thirty miles southeast of Zhongnan City. As soon as Cha Xiaoer heard Shopkeeper Wu say that Zhong Nangu was the Zhong Nan Mountain Stream, he hurriedly replied.

"I see, thank you both. Zhang Yifan thanked.

"Is Childe going to the Zhongnan Mountain Stream?" asked the shopkeeper Wu.

"That's what I'm going to do, what, is there anything wrong over there?" Seeing that Shopkeeper Wu was about to speak and stopped, Zhang Yifan asked.

"Childe, don't go deep into that valley, it is said that there are ghosts in there!" shopkeeper Wu persuaded with some fear.

"Oh, why did Shopkeeper Wu say this?" asked Zhang Yifan a little strangely.

"When Xiao Lao'er was young, he was more curious about many things, and he often heard people say that there were ghosts in the fog on the other side of Zhongnan Mountain Stream, and he was a little curious, so he went to find out, but he lost his way as soon as he entered the fog, and he felt as if he had encountered a ghost hitting the wall. In the end, I was lucky, and I fell into the mountain spring inexplicably and was able to get out of trouble with the flow of water, but I also fell into the root of this typhoid fever and never healed. Therefore, the little old man advised the son to think twice, and not to be curious and enter casually. Although many years have passed, Shopkeeper Wu is still a little scared when he talks about this experience.

"Thank you Shopkeeper Wu for reminding me, I will take care of myself. I have a bottle of Hearth's Warming Pill, which has some miraculous effects on typhoid fever, so I should ask for a thank you gift. Then Zhang Yifan took out a bottle of the pill he refined, although it was not a good product, but at that time he was curious that it had been soaked in mysterious well water, and the effect was much more than that of ordinary medicines for typhoid fever.

Shopkeeper Wu finally couldn't resist Zhang Yifan's sincerity after several excuses, so he accepted it and thanked him.

Then Zhang Yifan gave one or two pieces of silver to Cha Xiaoer, saying that the rest would be rewarded to the two without looking for it, and the two thanked them again.

Zhang Yifan left the teahouse, identified the direction, and rushed out of the city to Zhongnan Valley, which is the strange place known locally - Zhongnan Mountain Stream.

......

The scenery of Zhongnan Mountain Stream is strange and beautiful, and it is reasonable to say that it should be very attractive to tourists to enjoy the scenery, but in fact, locals rarely come here.

Some bold people from other places will never dare to come again after suffering from getting lost a few times, and they will spread the word from ten to hundred, resulting in a sparsely populated place.

However, because of this, this area is very natural, and you can occasionally see the footprints of wild animals such as foxes, tigers, bears and deer.

A curtain of waterfalls goes straight down the depths, and I don't know where to flow down the valley, and the valley and the mountain peaks are covered by thick fog, and it is so white that you can't see the inside clearly.

However, the main peak of Zhongnan Mountain is clearly visible not far away, it looks tall and verdant, and the top of the mountain is shrouded in clouds and mist, which is a beautiful mountain!

At this time, Zhang Yifan was standing in front of the valley covered by the thick fog, hesitating, looking a little distressed, and he couldn't pay attention.

After coming here, Zhang Yifan became more and more sure that this was the Xiuxianfang City he was looking for.

But he didn't know how to enter, and Su Tianjue's miscellaneous notes on cultivating immortals were not written in detail, but he just said lightly that someone would lead them in with a transmission note.

Zhang Yifan didn't know what the transmission note was, his eyes were black, and he didn't know what was at stake, so he didn't dare to break in. Besides, this dense fog has faint mana fluctuations, and it is obviously a formation, so he doesn't dare to move around at will, if he angers the master here, he will be in a bad situation.

Zhang Yifan decided to wait here to see if anyone else would come to the city, so that they could enter together. But after waiting for several hours, there was no one to see, which made him a little impatient.

Just as he was thinking about whether to break in and take a look, a voice came from the thick fog.

"This fellow Daoist, but he is looking for Zhongnan Gufang City?"

"Exactly, dare to ask Daoyou, how should I enter?" Zhang Yifan asked with great joy.

"Hehe, I am the deacon on duty at the south gate of this city, and I saw that the Taoist friend had been wandering outside for a long time, not like enjoying the scenery, so I took the liberty of asking. I'll take you into the market. ”

Then I saw an opening the size of a zhang in the thick fog, Zhang Yifan hesitated a little when he saw this, and then resolutely walked in.

"Welcome to Zhongnan Gufang City!" said a young man in a blue uniform with a young face smiling at Zhang Yifan.
