Here's the corrected version with improved grammar and flow:

The publicity effect of the Mittel Auction House was indeed remarkable. Just one day after Mo Yu handed over the weapons for auction, almost all the forces in Wutan City, both big and small, had heard the news. The excitement was palpable.
Unlike the advanced Xuan-level skills auctioned at the previous event, which only a few major forces could afford, many more people found weapons to be practical. Not only do they enhance combat capabilities, but they can also be passed down as family heirlooms.
When news about the Tiger's Mouth Breaking Formation Blade and the Dark Snake Shadow Sword spread throughout Wutan City, Mo Yu, who was residing quietly in his family's estate, was surprised by the uproar these weapons caused. The scarcity of high-quality weapons and the remote location of the city were evident in the reactions.
On the third day, the Xiao family also received an invitation from the Mittel Auction House. Several elders in the family were intrigued, recognizing the value of acquiring such fine weapons.
In the afternoon, Mo Yu decided to attend the auction in person. This time, he didn't wear his black robe; instead, he went openly.
Today's Mittel Auction was undoubtedly the most popular in the past six months. The spacious hall was packed with people, and the noise was overwhelming.
Upon entering the auction, Mo Yu found a spot towards the back of the auction area and settled in. As he leaned back in his chair, waiting for the auction to start, he noticed another wave of high-profile guests arriving. They were all influential figures from the three major families, clearly here for the weapons Mo Yu had refined.
Ya Fei, dressed in a red cheongsam that accentuated her curvy figure, took the stage. Her presence immediately drew attention from the crowd.
With a charming smile, Ya Fei addressed the audience, her mature allure heating up the atmosphere.
Mo Yu observed her with interest. If she were on Blue Star, top companies would compete to recruit her talent.
Ya Fei, aware of the effect she had on the crowd, smiled with satisfaction. She knew her beauty and charm were significant assets.
After setting the stage, Ya Fei raised her hand, dimming the lights. She then revealed a wooden box containing the Tiger's Mouth Breaking Formation Blade.
"The Tiger's Mouth Breaking Formation Blade was forged by an unknown master. It's incredibly powerful, like a tiger pouncing on its prey. The starting price is 30,000 gold coins!"
The announcement caused a stir. People eagerly began to place their bids.
"Forty thousand!"
"Forty-five thousand!"
"Forty-nine thousand!"
The bidding continued fiercely, and after nearly half an hour, the Tiger's Mouth Breaking Formation Blade was sold to Obaba, one of the elders of the Oba family, for 60,000 gold coins.
Mo Yu was surprised by the enthusiasm. The high price indicated the rarity and desirability of quality weapons. It was clear that Ya Fei's decision to promote the weapons was wise.
Next, Ya Fei presented the Dark Snake Shadow Sword. Its dark and sleek design, coupled with its ability to penetrate fighting spirit armor, made it highly desirable.
"The Dark Snake Shadow Sword is a formidable weapon for both stealth and combat. Its starting price is 40,000 gold coins!"
The bidding for the Dark Snake Shadow Sword was intense. A man in a black robe with a cold, menacing aura started the bidding.
"Forty thousand."
The room was tense as many people were intimidated by the black-robed man's presence. However, bids continued.
"Fifty thousand!"
"Sixty thousand!"
"Seventy thousand!"
The black-robed man raised the bid further. "Eighty thousand!"
"One hundred thousand!" the man in black announced coldly.
The audience was stunned. One hundred thousand gold coins for a weapon was an extravagant offer. Many speculated about the man's identity, noting he was unfamiliar in Wutan City.
The bidding reached an impasse. Ya Fei, sensing the auction was nearing its end, closed the deal with a final strike of her gavel.
Mo Yu, observing from the back, decided to slip out before changing into his black robe again and returning to the auction house.
The two weapons, which cost him only 20,000 gold coins to refine, were sold for a total of 160,000 gold coins. Mo Yu was impressed by the profit and affirmed that auctioning weapons was indeed a lucrative endeavor in the Dou Qi Continent.
Led by a maid to Ya Fei's office, Mo Yu was surprised to find that Ya Fei was not present. Instead, her personal maid, Xue Li, handled the transaction.
"My lord, these are the items you requested. Please verify them," Xue Li said, handing over a storage ring and standing aside.
Mo Yu, deducing that Ya Fei might be avoiding him due to their previous interaction, didn't take offense. He checked the materials, and after confirming their quality, transferred the refining materials and the remaining 50,000 gold coins into his own ring.
He handed the ring back to Xue Li and said, "Please inform Miss Ya Fei that I am very satisfied with this transaction."
With that, Mo Yu smiled at the nervous maid and left the office.
Next, it was time to reveal the Beast Ring and the Mighty Black Thunder Spear…
