Although the cards had learned many games, they had never played a game like this. So they randomly chose their positions. After a minute, all the cards were lined up. As they were lining up, William told Photon and Natalie to get ready. The AI systems they were equipped with were so powerful that learning this new thing was a piece of cake. "Let's turn around," Said William.

They had their backs toward the cards. "You can come to us." As soon as William spoke, the first card ran to William, the second to Photon, and then all the cards found their "owner". To avoid giving away information, the three aliens quickly moved away from each other and let the cards surround them.

William began to check his hand. As he examined, the smile on his face became more and more pronounced.

"God help me!" He whispered to his cards, "I must give you four aces and two jokers good credit. Did you already discuss and decide to come to me together?"

"No." Ace of Diamond said, "It's all luck, ha ha."

"Sometimes you have to trust in luck, my friend." Ace of Spade said.

William smiled, "Oh, of course I'll do that. But it is obvious that strategy is more important." Then he began to analyze, "As you can see, I don't have a five, six, seven, and queen, so I'm worried that all these cards might be in one of my opponents. That means they could play a bomb at any moment. Therefore, it is best to test them with single cards to see if they will play those cards. If it is, we are safer generally speaking. Otherwise, we still need to be vigilant. So, four aces and two jokers, please don't go out very early. This time I am alone, so you must wait until you hear me tell you to go out."

The cards nodded in support of his strategy.

Game started. Since William had both Ace of Spade and Red joker, he only needed to play all his cards before both Photon and Natalie did to win, and he had the upper hand. In order to make two, three and four into a straight, he played the extra three. Photon used a four, and Natalie chose a six.

"Does that mean six can't be a bomb?" Said Ten of Club.

"Yes, you are quite clever. But we can't say yet that they don't have a bomb." William replied calmly.

Nine of Diamond walked proudly onto the field, but William was soon under control -- Photon played a king. William deliberately tugged at the clowns, and they understood him.

Natalie and William did not control Photon, so Photon went on playing. Two twos stood in front of him, but Natalie didn't play. "Why is that?" William wondered, "Maybe she owns straight doubles, but it's also possible she still owns it after controlling. Cut you some slack."

Photon saw this and continued to play doubles. He played two fours, sevens, and eights in quick succession. This time William chose to act. After the two jacks were played, the other two did not even control. This was something William did not want to see, because he wanted to judge whether the queens were a bomb. However, now that he had the opportunity to play again, he would not let go.

A two, three and four were played at the same time. Photon played a four, five and six, while Natalie played a five, six and seven. "Just right," Said William, smiling as he told the eight, nine, and ten. William had only eight cards left in his hand, but there was still no one to control them.

"We're going to win this time." The two kings walked calmly out. William thought his two bombs could go out quickly, yet it was not expected that Natalie played the queen bomb. William chose not to control for now.

Natalie played a three to eight at the same time. Then, in amazement, she and Photon watched as all four aces came out at the same time. William turned around and strode confidently down the hall with the two clowns.

"Game over," He said with a wink. Photon and Natalie shook their heads resignedly and showed the remaining cards in their hands. "Master, you have a great lineup!" Natalie said admiringly.

"But, by his intelligence, our master would not necessarily have lost the game if he had not got such a good hand." Photon said. The hall resounded with cheerful laughter.

The two clowns returned to the sofas. "Aliens are really good friends! They are creative. We really want more tourists to know about us, especially aliens." Said Red joker, "However, we are little known here, let alone the aliens."

"Yes." Said Queen of Diamond a little sadly, "You were the first visitors. We always wanted more people to know about us and have fun with us, but we haven't done that yet."

"Ah, this is so terrible." Ranran said, "But I don't think you should promote your kingdom of playing cards now."

"Oh? Why?" Eight of Diamond asked, puzzled.

William told them about Black Tower and the sunken ship. All the cards stared and shone very brightly. This was their expression of surprise and fear. "Unlike what you think, it's dangerous out there." William's expression grew serious.

"Shortly before we came here, we found an endangered species." Aria said, "Our observations and analysis suggest that there is an extremely powerful weapon that killed a large number of individuals. However, due to the lack of evidence, we are not yet able to find out what kind of weapon it is."

The cards became tense at once. "To tell you the truth, I have heard strange noises," Said Five of Club, a little nervously.

"What's that noise?" Ranran asked him.

"It was like a very loud explosion... It was so powerful that you could feel the floor shaking even in this hall."

Six of Heart added, "And the guard diamonds on the ground have not been quite normal recently. Once, I saw them all turn black."

"Black?" The cards discussed nervously. In their eyes, black was certainly not a sign of luck. "What on earth is going on?" Two of Heart was confused, but the cards did not come to any conclusion.

King of Diamond stood up to stretch himself, when suddenly something fell out of his pocket. He looked at it and gave it a hard pat on the head. "Oh my God, I forgot to say that! Alien friends, I found this on my way out." He took something out of his pocket and handed it to William.

William looked at it carefully. It was animal fur, very soft and comfortable. William's keen eyes spotted a folded note tucked in the fur. He whipped it out. To his surprise, the words also seemed to be written by the same person who had written the note Charlotte the red seagull had found,

Do you think I would be content to let the red seagulls die out? No, quite the opposite! I want to make all creatures on this planet extinct, and even those on other planets! I know that no one can stop me. They will end up seeing their own lives end!

Oh, and I've heard that somebody is trying to figure out why red seagulls died? Ha ha ha, this is simply daydream! If he could come out alive from that terrible hell, he would know what had killed the red seagulls. But sadly the possibility of that happening is almost zero!

So please that person stop looking in vain! Give up the struggle quickly -- you have NO choice but to die!

"Good heavens!" Aria screamed, "Is this a coincidence?"

"No way, Aria." Replied Rebecca, "It must have been written by the same person."

The two clowns said, "You are in great danger, my friends. Why don't you stay with me for a few more days before you leave?"

"No, Mr Red joker and Black joker, you do not have to. Thank you for your enthusiasm, but we can't stay too long." Replied Rebecca.

The cards still wanted to retain, but William insisted on leaving as soon as possible. Photon told the cards that they had to quickly find the weapon that killed the red seagulls and do their best to stop that man.

"All right, then. In that case, please accept our gift." Having finished saying, Red joker knocked three times on the wall behind him.

A drawer slid slowly out of the wall. Black joker took out the object in the drawer, stood up, and went straight to William.

"We will give this gift to the alien tourists who visit us." He smiled as he handed William his gift.

William bowed to him and accepted the gift. The others leaned over to observe. It was a transparent box with a switch, and inside it lay a gorgeous deck of playing cards. The cards were also decorated with crystal clear diamonds of deep red or blue-green.

"It will remind visitors of the incredible place they have been to." Said Jack of Spade.

"Thank you very much indeed! The kingdom of playing cards is really a perfect place. But what is a pity is that we have a very important mission." Said Rebecca excitedly, "If there is a chance, we will definitely come again and enjoy with you!"

Ranran turned and was about to lead the party to leave when Jack of Diamond stopped her.

"I'm sorry, but our memory isn't perfect. King of Diamond forgot to give you this, which was wrapped up when he found the piece of animal fur."

A white diamond landed on the floor in front of Aria. "King of Diamond saw it saying, 'Take this to the terrible hell'," Jack of Diamond added. "Well, thanks a lot. Don't worry about us, and we'll be fine." Photon saw fear in his eyes and replied.

"Take care!" Said Queen of Club. "Play again!" Cried all the other cards.

William saw the cards lined up in front of them. He smiled and waved his hand. So did the cards. Then, the elevator doors closed.
