Is this the world of Yu-Gi-Oh? Ada thief!

After all, the appearance of Kaiba was just an interlude, and everyone in the Turtle Game Room happily studied the duel monster cards afterwards. Hayato and Yugi, who know the most about Duel Monsters, explained various aspects of knowledge to the newcomer Honda. Jonouchi, who had played for a while but was actually no different from Xiaobai, also sat aside obediently. Kyoko, on the other hand, was very enthusiastic about helping Grandpa Shuangliu.

Time flew by, and before you knew it, it was dinner time. Hayato and the others said goodbye to Yugi and went back to their homes.

Hayato returned home alone. As soon as he walked to the door and the key in his hand had not entered the keyhole, his attention was attracted by a letter placed under the carpet in front of the door.

【Hayato's personal introduction】

Picking up the envelope, Hayato saw these few words written alone on the envelope. However, he did not open the envelope in a hurry. Instead, he opened the door of the house first and said into the house: "I, I'm back."

After all, Hayato was not a neon person in his previous life, so saying "I'm back" when he went home was a bit unaccustomed.

However, Hayato's expected "You're back" didn't come from inside the house for a long time.

Confused, Hayato took off his shoes and left the entrance, and entered the house to find out. But what surprised him was that there was no one in the house, and it was completely empty and silent? It's not completely silent. The sweeper on the ground automatically starts running at the preset time, and the vacuum system makes a "buzzing" sound and faithfully starts cleaning the garbage on the ground.

Hayato is a time-traveler, and the parents of time-travelers have a high-risk profession. However, Hayato's parents are still alive in this life. The woman he saw just after waking up in this world is his mother in this life. Her name is "Kobayashi Sumire" and she seems to be the tax manager of the financial department of an international company. However, Hayato only heard the name of the company once, so he couldn't remember it.

As for Hayato's father, his name is "Hiroyuki Kobayashi" and he is a diplomat. Due to his profession, he has been abroad for a long time. Hayato has only traveled through time for one day, so until now, he has only seen his father in family photos. I couldn't really meet him.

However, what makes Hayato a little confused is that although his mother, Ms. Sumire Kobayashi, is often busy with company affairs, she should be on annual leave recently. Why is it that she is not seen at home? Could it be that he went shopping with his little sisters?

The only clue around Hayato was the envelope he picked up in front of the door.

After taking off his satchel, Hayato sat cross-legged next to the kotatsu in the living room. The tatami mat under his buttocks was quite comfortable. Hayato picked up a letter opener on the table and opened the seal of the envelope. He took out a letter and a bank card from the envelope.

Putting the bank card on the table, Hayato opened the letter first and read:

【Dear Hayato:

By the time you read this letter, your mother will probably be on a plane to London. I'm going to find your father. Speaking of which, we met in London.

…

Hayato read quickly. The letter was written by his mother, Sumire Kobayashi, and the general meaning was, "My son has grown up before I knew it. Mom is very relieved about you, so I am going to find your father during my annual leave this time."

The letter from her mother Sumire Kobayashi also said that after flying to London this time, she would probably stay there for longer than a month because her company would need to launch a trade plan there in the next period of time. A member of the ministry must also be involved.

Therefore, Hayato may have to live alone for a long time in the future. And that bank card is the pocket money and living expenses left by her mother, Sumire Kobayashi, to Hayato. It contains 200,000 yen. Whenever there is no money in the card, she will make a prompt payment. The card password is "030221".

"Is this what is called 'both parents are busy, but no sister has a house'?" After making a casual comment, Hayato breathed a sigh of relief.

Regardless of whether he could communicate with them normally, in the final analysis, the two parties didn't know much about each other. At most, they just lamented that Hayato's personality was different from what he showed in school, and there wasn't much. Suspect.

But if he had to face his original parents, Hayato would feel a lot of pressure. After all, parents know their children best, and if they show anything strange, they will definitely become suspicious.

Now that he doesn't have to spend all the time with his mother, Sumire Kobayashi, Hayato feels a lot more relaxed.

After rummaging through the refrigerator and finding canned eggs, vegetables and luncheon meat, Hayato opened a pack of instant noodles and decided to just have a simple meal tonight. While waiting for the water to boil, and with no one around, he woke up the system.

He skillfully entered the [Warehouse] module, and there were only four solitary items placed in the endless storage compartments - the card deck temporarily stored in the system, R-level card pack (Dragon), SR-level Card packs and R-rated optional cards.

With the idea of ​​saving good things for last, Hayato opened the R-level card pack (Dragon Family) first.

Different from basic card packs, the lowest card that can be released from an R-level card pack is an R-level card. However, as a price for improving the guarantee, the highest card pack that can be released is only an R-level card. There is no UR card as soon as it is shipped. possible.

The card pack that Hayato is opening now is a bit more special. The words "(Dragon)" following the name mean that the cards that appear in the card pack are limited to dragons and dragon-related support cards. What is very unfortunate is that Hayato's current deck is mainly composed of warrior-type monsters.

However, Hayato took a look and found that the "Dragon Killing Sword" was actually included in the dragon clan's support cards, so maybe some of the cards in the card pack could still be used.

[You have opened the R-level card pack (Dragon), congratulations on getting the following cards:

Cursed Dragon, City-Guarding Winged Dragon, Dragon Mirror, Baby Dragon, Dark Dragon King]

Good guy, Hayato calls him a good guy. Of the five cards that were drawn, four were from the Mortal Bone Dragon family, and they were all classic monsters.

However, Hayato had already expected it and knew that R-level card packs would not yield anything good, so he was not too excited. Moreover, the Dragon Clan is a powerful symbol, and even the few cards that are drawn are much stronger than the miscellaneous fish mortal bones in Hayato's own deck, and are worthy of being added to the deck.

The only confusion is probably this [Dragon Mirror].

"It seems that the only materials I have collected now are the Disruption King and the Dragon Knight Gaia. However, the Disruption King is not a dragon and cannot be used, which means it can only be fused with Gaia." Put the instant noodles into the boiling water, add the green vegetables and beat an egg. , Hayato thought, "But the problem is that I only have the materials but not [Dragon Knight Gaia]. Give me [Dragon Mirror] and I can't use it!"
