Lighthouse

Aiden was not interested. 

When it was their turn, only Lucien was allowed to enter. 

"One person per transaction." The guard emphasized. 

 Aiden had no choice but to wait outside. He stood at the left corner of the gate, gaping at the glass window. Watching keenly as Lucien exchanges the spirit stones. 

From outside view, no one can see anyone barehandedly carrying spirit stones. All of it is deposited inside each person's terminal. Hence, when the transaction is made, no gold coins will be taken out for the public to see. 

It was the first time Lucien got involved with trading. The man at the counter only asked him how many spirit stones he was willing to exchange. 

When he said all, he stretched out his hand where the wristwatch is. 

"Done. The gold coins are already registered on your terminal. A total of 1000 spirit stones were received."
