Having more than one method was already much better than they would have ever expected, but they were not really proving to be good enough for them.

"The third method can be the easiest and also the most difficult one. Its effectiveness depends on the working of the Bloodline Trinity formation's innate structure. The way it works is that it compares two bloodlines when activated.

The first one is the original bloodline which was inserted in it as a base, while the second will be the person who is trying to open it. The formation then judges how close or how far or close a bloodline is to the other and will open if it finds it sufficiently.

Now, what we can do is to use a person that has a bloodline far stronger than the original bloodline used to make the formation. Theoretically, the formation should find the first bloodline inferior and deactivate itself." Jing Luo explained.

Lin Mu and the rest heard his explanation and were lost in thought. All of the options seemed hard to use at first, but the second one was the most possible to them as of now.

"Can't I just use meld and break apart the vault?" Lin Mu asked Xukong.

"If your skill was high enough, you would have been able to do it easily. But the Bloodline trinity formation is not so easy. It is interwoven between the self destruction formation, such that even if a single inch of it gets unstable, the entire thing will blow up.

If you wanted to use meld to open it, you would need to specifically isolate the layer of the Bloodline trinity formation. But you yourself know how your control of Meld is. You can only control blocks of an area rather than fluidly picking it apart." Xukong answered.

"I see… that will make it quite hard." Lin Mu replied.

"Though the third method to override it using bloodline could work," Xukong spoke.

"It could? You mean with my Great Slumber Bear bloodline?" Lin Mu questioned.

"Yes, it is a bloodline of an immortal beast and should be far stronger than any other from this world." Xukong answered.

"Alright, we'll try if it works." Lin Mu replied and looked at Jing Luo.

"We'll use the third method." Lin Mu stated.

"Mmm," Jing Luo nodded his head, knowing that Lin Mu had a strong bloodline that he didn't fully know about.

"I don't know what exactly seniors will be doing, so I'll leave it all to you." Mu Tao said, finding it all to be a bit too complex.

"Do you need to do anything else to get it ready?" Lin Mu asked Jing Luo.

"No, with the third method it's just letting the formations activating on their own. I may need to stabilize a few of them during the process though, as it can get problematic. You just need to go and drip some blood on the door of the vault." Jing Luo instructed.

Lin Mu nodded his head and walked up to the door. He took out a dagger and pricked his thumb with a little difficulty. It was hard for him to even harm himself, as his defense was quite high at this point. He first needed to deactivate mortal strengthening scripture and then forcefully cut his silk using a high grade spirit weapon.

With the cut, some blood appeared on his skin. Lin Mu quickly put it on the door and waited.

~shua~

The formations started to light up, and runes appeared all around the vault. Mu Tao and Mu Niu gulped their saliva, feeling nervous. Each opening of the vault was associated with trouble for them at this point and thus they mostly had bad memories about it.

Lin Mu closed his eyes and let the formation work, while Jing Luo monitored it for any abnormalities. 

~HONG~

A humming sound was heard as the first layer of the formation unlocked, much to the surprising of the Mu clan members. But then came the interruption.

~DENG~

As if a metal plate had been hit, a screeching sound spread in the hall. More runes appeared from the formation array and formed into the shape of an old man. The old man had no facial features except a long beard.

The runes that made his body were glowing read and flickered from time to time. Upon his appearance, the opening of the formation array stopped.

"That's the original bloodline used to make the Formation array," Jing Luo informed.

Lin Mu narrowed his eyes and became a bit tense. In the next moment, his body stirred and an imposing presence exuded from his body. 

~ROAR~

The roar of a beast echoed in the hall, the source of it coming from Lin Mu's body. Then, the illusory figure of a large bear appeared over Lin Mu's body and started to enlarge. This figure belonged to none other than the Great Slumber Beast!

The illusory beast looked at the illusory man with anger in its eyes. To it, the old man was an enemy that was blocking it from getting what it wanted.

~ROAR~

The Great Slumber Bear roared and raised its paw up into the sky. The long claws shined as if they were made of the highest quality steel and slammed into the old man.

~boom~

A visible explosion appeared as the old man was blown into smithereens. Mu Tao and Mu Niu were left gawking as they saw what was supposed to be their ancestral bloodline being destroyed, as if it was a paper toy.

~ROAR~ 

Having destroyed the old man, the Great Slumber bear felt pleased and raised its head before letting out a roar. While its roar could not get out of the underground area, the pressure exuded from it was felt by everyone in the city.

Their bodies involuntarily shuddered and some of them felt weak. Thankfully, this state only lasted a couple of seconds before fading away. If it had lasted any longer, people would have definitely started to faint.
