Before Departure, the Mental Immunity Skull!

To be honest, the speed at which Yu Changge's Soul Power Level increased was somewhat beyond Qian Xunji's expectations.

At the age of ten, reaching level thirty-nine is an extremely rare cultivation speed.

But Qian Xunji didn't have too many doubts; he attributed it all to several external factors.

First and foremost, it was the Light Attribute Immortal Herb that Yu Changge had previously consumed that completely transformed his talent.

Secondly, there's the Soul Power feedback that Xiao Huang, as a rare External Beast Martial Soul, provides to Yu Changge during its autonomous cultivation, which is equivalent to the two of them cultivating simultaneously.

Finally, and most importantly, there is that Spirit-Condensing Wisdom Skull over nearly 70,000 years.

Although Spirit Bone themselves cannot directly increase Soul Master's Soul Power Level, high-quality Spirit Bone can actually promote Soul Master's cultivation process.

For example, that Head Spirit Bone greatly enhanced Yu Changge's spiritual power.

With increased mental strength, one's perception of the surrounding energy becomes clearer, allowing for better absorption of external energy into the body.

In other words, his efficiency in acquiring Soul Power through daily meditation has been significantly improved.

Given these combined factors, it's not surprising that Yu Changge has achieved her current cultivation speed.

Just as Qian Xunji was pondering, Bibi Dong walked out from the side.

"Teacher, I want to go too!" Bibi Dong looked at Qian Xunji with a serious expression.

"I've already discussed this with Changge. I also need real combat experience, and the Great Soul Arena is the most suitable place for me."

Qian Xunji looked at the two people in front of him and suddenly felt troubled.

He naturally knew that Bibi Dong's words made sense; flowers in a greenhouse cannot withstand wind and rain, and she too needed to experience trials.

However, as the Pope of the Spirit Hall, he has endless affairs to handle every day, and he also has to start the Second Angel Trial, so he can't leave the Spirit Hall for too long.

Although these two people have decent Soul Power, they are only at the Soul Elder level.

Qian Xunji was really worried about sending them to Heaven Dou City alone.

If anything goes wrong, the consequences would be unimaginable.

"Yue Guan," Qian Xunji called out in a deep voice.

The sound wasn't loud, but it carried clearly outside the main hall.

The next moment, a tall and slender figure appeared in the Pope Palace; it was Yue Guan, who had just broken through to Ninety-Fifth Rank.

He had been standing guard outside the Pope Palace, ready to be at Qian Xunji's beck and call.

"Your His Holiness the Pope, what are your orders?" Yue Guan bowed respectfully.

Qian Xunji looked at Yue Guan, then at Yu Changge and Bibi Dong, and sighed helplessly.

"Since you insist on going to the Great Soul Arena for training, I won't stop you. It will indeed be beneficial to your growth."

"However, Heaven Dou City is not like Spirit City. For your safety, Yue Guan needs to accompany you."

As he spoke, Qian Xunji looked at Bibi Dong with a serious expression. "This trip to the Heaven Dou City Great Soul Arena is for training, so Dong'er, you cannot use your Second Martial Soul."

"This also means that your Martial Soul Fusion Skill is no longer usable."

Bibi Dong exclaimed, somewhat dissatisfied, "Teacher, if I can't use the Martial Soul Fusion Skill, my combat power will decrease significantly."

Bibi Dong's three Soul Skill of the Death Spider Emperor don't have much offensive power.

Qian Xunji shook her head. "You're going on this training trip with Changge. If you expose your Twin Martial Souls talents and someone with ulterior motives finds out, then no matter how much I cover for Changge, he's still at risk of being exposed, do you understand?"

If Bibi Dong had only used the Death Spider Emperor in the Great Soul Arena, even if others knew about it, they might not necessarily associate it with Bibi Dong of the Spirit Hall.

After all, there are so many Soul Master on the continent who possess Martial Soul, so the Death Spider Emperor couldn't possibly be Bibi Dong's exclusive possession.

Furthermore, due to the immortal Immortal Herb, Bibi Dong's appearance changed after being possessed by the Death Spider Emperor, which also provided a good hiding point.

However, if Bibi Dong reveals her Second Martial Soul, she will likely be directly targeted by the Spirit Hall.

And the Little Golden Dragon beside Bibi Dong has External Beast Martial Soul; could it be related to Yu Changge?

That's really hard to say!

However, Qian Xunji believes that if things are exposed at that point, so be it.

Yu Changge's evolved Martial Soul has never been shown to the outside world. How much imagination would it take to connect the two of them?

He wouldn't have believed it if someone hadn't told him it with their own eyes.

Bibi Dong understood this as well, and could only say "Oh," before saying, "Fine, then I'll rely on my control and poison to defeat my opponent!"

Yu Changge smiled and said, "Then you'll have to prepare some antidote for them. With the poison of your Death Spider Emperor, plus your level, I'm afraid not many people can withstand it."

Bibi Dong snorted arrogantly, "Then you withstood it, didn't you? My poison barely affected you before it was completely dissolved by the Holy Light Power within you."

Yu Changge simply smiled and offered no explanation.

Actually, given Xiao Huang's current power level, it would be quite difficult for him to completely neutralize Bibi Dong's poison.

After all, Xiao Huang's current quality is only at the initial top level, while Bibi Dong's Death Spider Emperor is at the highest level.

Under the Self Martial Soul Fusion Skill, its quality should reach the super level.

It was only because he possessed Immunity to All Poisons due to consuming the Infernal Delicate Apricot and the Octagonal Mysterious Ice Grass that he truly suffered; otherwise, he would have been in real trouble.

That evening.

Qian Xunji summoned Bibi Dong to the inner chamber of the Pope Palace alone.

Qian Xunji looked at Bibi Dong, then flipped his right hand, and a Spirit Bone emitting a dark purple light appeared out of thin air in his palm.

This Spirit Bone was surrounded by a faint spiritual fluctuation, and its appearance was a complete skull shape.

"Dong'er, tomorrow you will be going to Heaven Dou City with Changge."

"Consider this Spirit Bone a farewell gift from your master. Absorb it here tonight."

Bibi Dong stared at the skull radiating purple light before her, her heart pounding uncontrollably. "Teacher, this... this is for me?"

Seeing Bibi Dong's flattered expression, Qian Xunji couldn't help but laugh.

"What? Weren't you the one who kept asking me for a Head Spirit Bone? Now that I've given it to you, you're hesitant to accept it?"

"This is a Head Spirit Bone that is nearly 80,000 years old; its name is the Mental Immunity Skull."

"This Spirit Bone was produced by a Ten-Thousand-Year Soul Beast, and its attributes are very suitable for your Death Spider Emperor Martial Soul."

Eighty thousand years!

Bibi Dong was completely stunned.
