In The Dragon Ball Universe With The Summoning System

That was the worst thing I have... ever experienced.

We went to the normal clothes stores and then they got hungry, so they dragged me to every cafe to find something to eat.

Then! We went to various factories and junkyards to gather materials for the droids that Lucy took a liking to.

I thought it'd be easy with my Saiyan stamina, but no. It wasn't... it was absolutely exhausting, not physically. But mentally, I was completely exhausted, so when we got back to my home, I just went straight to bed, while Launch and Lucy just spoke to some of the residents, but the first person they went to was Ed. Probably to give him the materials for the droids, I think he was happy.

But now, I'm just going to lie here until I can get over that trauma!

I got up a couple of hours later, well rested.

"So, how do I use Energy Assimilation?" I asked the system while laying on my bed.

[Simply command me to use it for you, like you do with Cross-Universe Summoning, Fusion and your other abilities] The system stated... almost sarcastically.

"Okay... Energy Assimilation" I said, using the command, and suddenly I saw a blue-ish light appear before me and slam into me at full force.

"Gah! What was that!" I shouted.

'And more importantly, what energy did I assimilate with?' I thought

[The energy you have assimilated with is Water Chakra] The system stated.

'So... I can use water-based jutsu?... Okay, this may be good... especially since I have Zabuza around to train me' I thought, a grin creeping up on my face.

'I'm definitely going to learn the water dragon jutsu from Zabuza!' I thought excitedly.
