With both of them working synergistically, they manage to dive deeper into the basement, however this is the first time that Blanc ever use this magic, not only that, this is also the first time that Lydia have to use her heightened sense to gather more information and without a doubt, this is their first time having their mind connected together (literally), thus they find themselves in a pretty rough situation, nevertheless, the success of the cleansing operation depend on how much information they managed to gather beforehand, so they will leave no room for error

(Blanc, I can hear some voice on the right side, can you focus your magic more toward it) [Lydia]

(Yeah, with our mind connected, I can faintly hear the voice that you meant, alright, here goes) [Blanc]

With that, Blanc shift his earth sonar magic toward the voice that they hear and managed to get some vital information

"Everything is ready sir" [Soldier]

"Excellent, and I believe those barrier have been implanted into their mind?" [Noble]

"Yes, with that, you don't have to worry of them running away" [Soldier]

"Fufu, not like they have a chance to run away to begin with, but I don't want those church people to complain afterward" [Noble]

((!!)) [Blanc, Lydia]

(Blanc, can you hear that!?) [Lydia]

(Faintly yeah, but I believe they mentioned the word running away and church, does that mean...) [Blanc]

(Yeah, those guy are gonna get sold to the church!) [Lydia]

(This is a vital information) [Blanc]

(definitely!) [Lydia]

"Sir, their food are running low, should we supply more of it" [Soldier]

"Nah, they can survive for two more day, but it would be a drag if there are too weak during that day, so supply them some trash on the evening two day from now" [Noble]

"Yes sir" [Soldier]

(This is bad) [Lydia]

(What is it Lydia?) [Blanc]

(They are gonna be sell from two day onward!) [Lydia]

(huh!) [Blanc]

when Lydia said that out loud (to Blanc mind), he unconsciously let out more mana than usual

"Huh?" [Mage]

"What's wrong" [noble]

"I believe i sense some mana from underneath us just now" [Mage]

"WHAT!" [Noble]

"It's too little to consider us mana earthquake, so that can only mean..." [Mage]

((SHIT!!)) [Blanc, Lydia]

(Lydia, i am withdrawing my mana) [Blanc]

(understood!) [Lydia]

"It can only mean those bastard are trying to escape" [Mage]

"How foolish" [Noble]

"No, we don't do anything believe us!" [Father Dwarf]

"No please don't hurt us anymore!" [Mother Dwarf]

"Silent, you both inferior commoner, and you too, not only you are a commoner, but a dwarf nonetheless, guard!" [Noble]

"Yes sir" [Soldier]

"Give me those torch" [Noble]

"No, please don't, I am begging you" [Father Dwarf]

"Consider this a punishment, or you want me to burn your wife and child?" [Noble]

"...., please don't" [Father Dwarf]

"Shut it, hey bring that kid over here!" [Noble]

"No please don't do that!" [Mother Dwarf]

((!!)) [Blanc, Lydia]

(That Bastard!) [Lydia]

(Lydia, Don't scream!) [Blanc]

With that, Blanc and Lydia sensory link connection is broken, and Blanc earth sonar magic as well as Lydia Dragonewt technique are quickly dispel. With how drastic everything happen, Alfin mana control become distorted causing her to lose control and thus making her illusion magic dispel. With her original appearance now expose, Emma quickly cover Alfin with her cold winter jacket and bring her somewhere else, Rais do the same to Blanc and Lydia

The three of them, after exhausting theirselves, try to grasp for air. Seeing as how exhausted they are, Rais and Emma quickly take out a bottle of water and give it to them. After drinking the water for a little bit, Alfin take out three mana vile and give two of it too Blanc and Lydia, for which they take without even saying thanks, clearly showing how much mana they have consumed

"Emma, Rais, both of you should also have some mana vile, here" [Alfin]

Princess Alfin took out two more of it, unlike the three of them, Emma and Rais only drink half of it and store another half for later use

""Thank you Princess Alfin"" [Rais, Emma]

"Hoi Lydia, we forgot to said thank you to Princess Alfin" [Blanc]

"!" [Lydia]

""Thank you Princess"" [Blanc, Lydia]

"Don't worry, you guys are clearly tired after large amount of mana is used, and those sudden spell dispel also cause more mana wastage, so it's understandable" [Alfin]

Alfin understand it as she herself in the past will experience this symptoms and it felt really terrible, that's why she doesn't mind Blanc and Lydia behaviour, but those two on the other hand feel that they have done something outrageous thus continuously apologize to her

"Like I said it's ok, more importantly, did you guys find anything" [Alfin]

"Oh yeah, well you see..." [Lydia]

Lydia explain what she heard and what happened that cause the sudden dispel of magic

"I am sorry, not only I did a stupid mistake, but those mistake cause the guy to be..." [Blanc]

Blanc clearly in a state of frustration, he can't even finish his sentence

"Not only that, I can't even grasp their number, if only I am a better magician, or if only teacher Azumi is the one that use this magic, it will never happen!!!" [Blanc]

"Hey Blanc, it's not your fault, i am also to be blame" [Lydia]

"Both of you, you guys did well" [Alfin]

""But princess..."" [Blanc, Lydia]

"Well, to begin with, both of you manage to find a vital information, not only that, now we have a new method to investigate the other noble, as for your mistake, how about you make this operation a success and apologize to them directly afterward and see whether they are angry or not" [Alfin]

""..."" [Blanc, Lydia]

"Blanc, Lydia, it's alright, I will also support both of you, if you guys still feel guilty to face them afterwards, Guz, Blade and I will accompany you" [Emma]

Emma try to cheer them up, then it's Rais turn

"Right now, as Princess Alfin rightly said, we have a new method to investigate the other noble, so instead of feeling down, you should be proud as your information will lead to their freedom!" [Rais]

Blanc and Lydia look at eachother for awhile and nodded with determination

Slowly the both of them cheer up a bit, with that, they go their next location swearing to themselves not to make any mistake and gather more information using the same method
