The grudge between Bibi Dong and the Tang brothers, Tang Hao and Tang Xiao, actually had something to do with Ah Yin.
As a 100,000-year soul beast who had taken human form, Ah Yin needed to stay close to humans in order to cultivate. So ever since her transformation, she had been living in a small village near the Star Dou Great Forest, within the Kingdom of Haagen-Dazs.
However, one day, a division of the evil soul master organization led by Bibi Dong—Evil Nether Hall—came to this village and began a massacre and blood sacrifice.
At the time, Ah Yin was only a Level 48 Soul Sect. While her martial soul, the Blue Silver Empress, combined with her Blue Silver Domain, allowed her to protect herself against the evil soul masters led by a Soul Sage, she could do nothing to stop them from slaughtering the villagers.
Coincidentally, after leaving the Clear Sky Sect, Tang Hao had just broken through to Level 71 as a Soul Sage, while Tang Xiao was at Level 78.
After two years of tempering, Tang Xiao had just reached Level 80 and was planning to enter the Star Dou Great Forest in search of a soul beast suitable for his eighth soul ring. It was then that they happened to pass by.
When they noticed the disturbance, Tang Hao and Tang Xiao rushed over together and saw Ah Yin being surrounded by evil soul masters.
With Ah Yin's stunning beauty and her gentle, graceful temperament, just one look was enough to instantly captivate the hearts of both Tang Hao and Tang Xiao.
The two brothers charged forward together, rescued Ah Yin, and drove off the evil soul masters.
Unfortunately, the village had already been destroyed in the massacre.
As a transformed 100,000-year Blue Silver Empress, Ah Yin was different from other soul beasts. Very few people chose to hunt Blue Silver Grass for soul rings, and 99.999% of them wouldn't produce a ring anyway.
Because of this, Ah Yin had always been kind toward humans and had hoped that soul beasts and humans could live in peace. Otherwise, she wouldn't have taken human form to begin with.
It's worth noting that most 100,000-year soul beasts, like Titan Giant Ape and Sky Blue Bull Python, never chose to take human form due to their deep distrust and hostility toward humans. The ones who did were generally very friendly toward humanity.
Ah Yin had lived in that village for nearly 10 years and had developed deep emotional ties with many of the villagers. Combined with her kind heart, this made her furious—she wanted to avenge the villagers and prevent other innocents from suffering the same fate.
When Tang Xiao and Tang Hao heard that Ah Yin wanted revenge, they became extremely worried for her safety and insisted on accompanying her.
It's also worth noting that after agreeing to travel together, Tang Xiao entered the deeper areas of the Star Dou Great Forest and successfully found a soul beast suitable for his eighth soul ring, breaking through to Level 81 as a Soul Douluo.
Though Ah Yin, knowing Tang Hao was about to break through to Soul Douluo as well, tried to constantly activate her Blue Silver Domain to hide her identity, it was impossible to keep it up all the time. Eventually, through a slip-up, Tang Xiao discovered who she really was.
But what was Douluo Dalu also known as? The land of love!
Even after learning Ah Yin's true identity, Tang Xiao—who had already fallen deeply in love with her—chose to pretend he hadn't noticed and kept it secret from Tang Hao.
After that, the two brothers continued following Ah Yin as she pursued the evil soul masters to avenge the village.
But unfortunately, the group they were after weren't just random evil soul masters—they were a squad personally brought out of the Slaughter City by Bibi Dong.
At this point, the organization had grown to over 1,000 members, and each squad was made up of full, organized teams of soul masters. Many of them included flying-type soul masters as scouts.
So even though Tang Hao and Tang Xiao, along with Ah Yin, were able to locate the evil soul masters occasionally and kill a few stragglers, they could never truly harm the core of Bibi Dong's Evil Nether Hall.
Eventually, Bibi Dong received news about the Tang brothers from her subordinates. Although she could have mobilized her forces to eliminate them, she hesitated.
Killing Tang Xiao and Tang Hao could provoke a devastating retaliation from the Clear Sky Sect—especially if even one of them escaped.
At this stage, Evil Nether Hall couldn't withstand a vengeful, crazed Super Douluo leading a group of powerful Soul Saints and Soul Douluos on a suicide mission for revenge.
So instead of clashing with them directly, Bibi Dong ordered her people to avoid confrontation.
As for Ah Yin's identity, Bibi Dong had yet to realize it.
Although she had brought many Soul Emperors and Soul Sages out of the Slaughter City, Soul Douluos were rare. Most of the powerful figures in the Slaughter City were already under the Slaughter King's control, and he wouldn't just hand them over.
Even after leaving Slaughter City, Bibi Dong led her forces in ruthless slaughter and blood sacrifices across the Frostwind Wastes and the Northern Highlands, targeting nomadic and barbarian tribes. But advancing from Soul Sage to Soul Douluo—or from Soul Douluo to Titled Douluo—was incredibly difficult.
Even with the boost from blood sacrifices, soul masters would still hit bottlenecks at those crucial stages.
If evil soul masters could just blood-sacrifice their way to becoming Titled Douluos, that dark era of evil soul masters would never have ended in the first place.
"Damn it! They escaped again!"
Tieling Village.
Tang Xiao, Tang Hao, and Ah Yin arrived only after Bibi Dong and her forces had already finished the blood sacrifice and retreated.
When they saw the ruins, bloodstains everywhere, and not even a single corpse left behind, both Tang Hao and Tang Xiao clenched their fists in fury.
At first, they hadn't cared much about these evil soul masters—they simply wanted to protect Ah Yin.
But after chasing them over and over, only to see the evil soul masters slip through their fingers like eels, the brothers—once famed geniuses proud of their strength—felt deeply provoked and humiliated. They were starting to lose their cool.
After another failed attempt to track them down, they could only leave with Ah Yin and return to Sino City to recover.
But on the road back, a golden sun suddenly shone from the sky as two figures descended rapidly in front of them.
One was clad in golden robes, tall and upright, with long golden hair flowing behind him. His sword-like brows reached his temples, his nose was straight and prominent, and his star-like eyes radiated unmatched handsomeness.
He wore a faint smile, and six pairs of radiant golden wings stretched out from his back as he was bathed in holy golden light—none other than Qian Xunji.
He was accompanied by Chrysanthemum Douluo Yue Guan and Ghost Douluo Gui Mei.

Author's Note (the fanfic author's, not mine): In the original novel, Ah Yin was at Level 70 when she gave birth to Tang San.
It's currently Year 2620 of the Douluo Calendar—11 years before Tang San's birth. So Ah Yin's current cultivation shouldn't be too high. Level 48 is appropriate.
1 year to reach Soul King,
4 years to reach Soul Emperor,
5 more to reach Soul Sage—still reasonable.
