It is not easy to refine a boat that crosses the Styx.

The boat is mainly made of the golden yang magnet wood given to Shen Lang by Emperor Xuelan, and the auxiliary material is the natural and earth treasure of the Yang attribute, which is used to reinforce the boat.

Generally speaking, after crossing the Styx River, the boat that crosses the Styx River is abandoned, and the yang energy contained in the boat is basically corroded.

The river water of the Styx is where all kinds of evil auras gather between heaven and earth, such as turbid air, evil air, foul air, etc. are gathered. The dead air is filled with a large number of ghosts floating, and the boat must be strong.

Secondly, the sky of the Styx contains extremely twisted space power, and cannot fly over, so it can only be crossed by a small boat.

In this way, only by speeding up the speed of crossing the river by the small boat as much as possible can the time to cross the Styx.

In this way, a top-level acceleration formation is required to be arranged on the boat.

The last top material that Lan Xian'er lacks is called "The Essence of Wind Spirit".

Wind belongs to wood, and the essence of wind spirit is produced from wood-attributed spiritual ore. There may not be a few drops of wind spirit essence in a large wood-attributed spiritual ore, which shows the rareness of this thing.

The essence of Feng Ling is a rare material with a wide range of uses. The most common one is to portray powerful wind attribute formations and refine flying magic weapons.

Moreover, the essence of this wind spirit has a magical effect of diligent cultivation on the wind attribute demon cultivator below the Void Refining Stage and the monks with Feng Ling roots!

All in all, this thing is extremely rare.

Fortunately, Shen Lang got a storage ring from the elder of the Lianhua clan before. The elder of the Void Refining Stage is extremely valuable, and the big sky crystal stones in the storage ring are nearly 400,000!

No matter how expensive the essence of Feng Ling is, Shen Lang can afford it as long as it leaks out.

Just this day, Lan Xian'er returned from out and told Shen Lang a good news.

"Mr. Shen, Xian'er just got information about the essence of the wind spirit. It is said that five days later, the Nandao Chamber of Commerce in Tiannan City held a large-scale auction, and a small bottle of the essence of the wind spirit will flow out at the auction." Lan Xian'er said in surprise.

Shen Lang said gratefully: "Xian'er, thank you for helping Shen find materials during this period. I'm in trouble. Shen's body has completely recovered, so I'll go to the auction with you."

"Okay." Lan Xian'er nodded slightly.

The two left the cave and flew towards Tiannan City.

The teleportation array on Tiannan Island is under the jurisdiction of the city master and is not allowed to be used by outsiders. Shen Lang and Lan Xian'er can only fly and rush.

Lan Xian'er's flying magic weapon was extremely fast, and she arrived in Tiannan City in most days.

Tiannan City is the largest city on Tiannan Island, with a radius of millions of miles. There are a large number of monks in the city, which is comparable to a prosperous medium-sized city of the human race.

The most elite monks in the entire Tiannan Island gathered in Tiannan City. Of course, the monks in the God Transformation Stage are still top-notch and not many.

Before they entered the city, they were stopped by the guards patrolling Tiannan Island. The reason was that they had to pay a certain amount of small Tian crystal stones when entering Tiannan City, which was the rule set by the city lord.

Seeing that the two patrol monks in the early stage of the Nascent Soul dared to ask for the Xiaotian Crystal from him, Shen Lang felt a little unhappy, but he did not have any disputes and directly paid the specified amount of Xiaotian Crystal.

The two of them randomly found a restaurant in the city for a few days.

The South Island Chamber of Commerce is the largest chamber of commerce on Tiannan Island and an industry under the City Lord's Mansion. The large-scale auction held by the South Island Chamber of Commerce is once a decade and is a grand event on the entire Tiannan Island, attracting countless powerful monks to participate.

On the day of the auction, the entire South Island Chamber of Commerce was very lively, and the streets were crowded with people, one after another.

The monks on Tiannan Island are like hodgepodges, with all kinds of appearances, including lion-headed men in armor, cat women in flowing feathers, and young humans holding folding fans.

Although the race is chaotic, it is obvious that there are more human monks.

Not all monks can participate in large-scale auctions. Only monks with the Nascent Soul stage or above are eligible to enter the venue. Cultivators who have not reached the Nascent Soul stage cannot enter.

Shen Lang and Lan Xianer wore masks, deliberately suppressed their breath, and walked into the venue in a low-key manner.

The auction venue has a huge space, with tens of thousands of square meters, enough to accommodate as many as 100,000 people!

When the two of them arrived in the venue, they were almost full.

The two found an adjacent seat and sat down, waiting patiently for the auction to begin.

At this moment, a loud shout suddenly sounded outside the venue.

"Young City Lord is here!"

As the shouts fell, the entire auction venue was in a state of chaos.

I saw a large number of monks in the city lord's mansion wearing armor, surrounded by a short and fat young man in brocade clothes, walking into the auction venue, attracting a lot of attention.

That short and fat young man is not the young city lord Sun Zihao!

"This guy is here too?"

Shen Lang's eyes shrank.

Lan Xian'er also frowned slightly.

Both of them hated this young city lord a little, and just hoped that this guy would not ruin their good things.

"Young Lord, please!"

The head of the South Island Chamber of Commerce personally led Sun Zihao to a large golden chair at the front of the venue, with a look of flattery.

Sun Zihao sat down, crossed his legs, and two beautiful maids massaged his back behind him, which was so comfortable.

The old man in black robe was still standing beside Sun Zihao, silent and serious.

Soon, the auction began.

A late-stage Nascent Soul girl in a pink skirt walked to the booth. Her facial features and tall and hot figure made many male cultivators in the venue look straight.

"The little woman is honored to host today's auction on behalf of the South Island Chamber of Commerce! First of all, we welcome all fellow Taoists to participate in this large-scale auction, and warmly welcome the young city lord to visit. The South Island Chamber of Commerce will shine brightly!"

After the girl gave her opening remarks, the auction began.

"The first treasure to be auctioned is called the Frost Sword, which is the lowest-grade spiritual treasure of the prehistoric world! This treasure..."

Tiannan Island thinks it is located in a remote place, and resources such as the prehistoric spiritual treasure are extremely scarce. A low-quality prehistoric spiritual treasure can be called the top-level treasure of the cultivators in the middle of Tiannan Island!

What's more, it's a popular magic weapon for flying swords.

The atmosphere of the venue was completely ignited, and the first prehistoric spiritual treasure was sold at a high price of 35,000 Great Heavenly Crystals!

Shen Lang was a little surprised. If it were on the territory of the human race, a low-grade prehistoric spiritual treasure of flying swords was sold at most about 15,000 Datian crystal stones, which had more than doubled in Tiannan Island.

The auction continued, and Shen Lang just looked at the treasures leaked from the auction with the attitude of watching the show, basically nothing he could see.

When the auction was halfway through, the small bottle of Feng Ling's essence finally flowed out.

"The next treasure is called the essence of Feng Ling, which is an extremely rare spiritual liquid."

As soon as he finished speaking, a maid walked out from behind the booth, carefully holding a blue jade porcelain bottle and placed it in front of the booth.

The girl in the pink skirt who was hosting the auction opened the porcelain bottle, and a blue wind swept across the entire auction venue, causing the monks' robes to roar.

Such a magical ability caused a commotion in the monks off the field.

"What is the essence of the wind spirit? It seems to be very powerful."

"It is said to be a top-level wind-attribute spiritual liquid, which can arrange formations and refine flying magic weapons, and can also improve the cultivation of wind-attribute cultivators!"
