After open the secret door, Taepung goes down by a ladder that connect the door and his V-Pups clinging to Taepung to follow him goes down. After climbing down, they see a small room made by wood and look really old.
"Oh my god!" - The V-Pups said
"So this really a secret basement!" - Taepung said and look around
"It's look really old! It's just like its has existed for hundred of years!" - Ares said
"Oh yeah! You right!" - Taepung said and then he see two big wood boxes and a old chest.
"Hey guys! Look!" - Taepung said and points at two boxes.
"Hey! What is it?" - Zeus said
"I don't know! Just come!" - Zeus said.
And then Taepung and his V-Pups goes to near two boxes.
"I really don't know what my parents put in these!" - Taepung said.
"Just open it!" - Zeus said.
"Okay! But I afraid that its locked! If its locked and can't be opened, it's like ours efforts are wasted!" - Taepung said.
"We know it! But just open! What if its not locked?" - Athena said.
"Yeah! Just try!" - Taepung said and then he touches the box and surprisingly, its didn't locked!
"Hey! Its didn't locked!" - Taepung said.
"See? I said!" - Athena said.
"Okay! Let's open it!" - Taepung said.
"Right! I count to three, you open the box! Okay?" - Zeus said.
"Okay!" - Taepung said.
"One...Two...Three!! Open!" - Zeus counts to three and then Taepung open the box and surprisingly, inside the box is many small books and a blue sword.

"Holy crap!" - The V-Pups said!
"That isn't...my grandfather's Seiken?" - Taepung surprise with what he found inside the box.
"This is your grandfather sword called Seiken, Taepung?" - Zeus said.
"Yeah! I heard that my father said that my house have a place to places my grandparent's holy swords and Wonder Ride Books, so this is the place!" - Taepung said.
"So these small books is called Wonder Ride Books?" - Ares asks.
"Yeah! And this sword are called by Seiken that means 'holy sword' and its and these Wonder Ride Books has been used by my ancestors and then pass to my grandfather and my father!" - Taepung said
"And then you!" - Zeus said.
"Yeah! And the cards I used to power you guys its from these Wonder Ride Books!" - Taepung said.

"You mean Lion Warrior, Brave Dragon and Victorious Bird?" - Zeus asks
"Yeah! That's it!" - Taepung said.
Suddenly, his Olymulyist Watch starts flashing and sounding alarms.
"The Anders! They came! Let's go, guys!" - Taepung said.
"Okay!" - The V-Pups said.
"I will take the sword too!" - And then Taepung takes the Seiken and he and his V-Pups get out the basement and goes to the city.
