爆炸一直波及到了水晶宫。巴斯一个没站稳，差点摔了一跤。悠悠赶紧上前扶了他一把。
巴斯听到爆炸声，吓了一跳。但是他脸上震惊的表情很快换成了兴奋的表情，他冲着悠悠喊道，“太棒了，太棒了！你的武器我全要了！”
“好吧，咱们商量一下价格。”悠悠朝巴斯笑了笑，说道，“我们带的武器很多，你肯定会满意，可是你的人鱼质量太一般了。”
“你放心，多送你两条怎么样？以后我如果抓到更多的人鱼，都给你留下来。”巴斯大笑地说道。
当确认巴斯没有秘密藏着更多的人鱼以后，悠悠笑着说道，“那也行，这次多换几条。以后您如果抓到了更多的人鱼，我们再来。”
***********************
水晶宫的后院里，还是那一处宽阔的沙滩上。仁默默念咒，不一会儿就看到仁变得越来越大，越来越高，直到宽阔的沙滩全部占满。
小伙伴们每个人扛着大大小小几十个塑料玩具，他们的另一边，渔人们用麻袋装着老老少少二十几条人鱼从水晶宫出来。两队人马各站一边，看着对方的东西很高兴。
巴斯和渔人们小心翼翼地检查着悠悠带来的“世界上最先进的武器”，生怕一个不小心弄响了，哪里又会爆炸。小灵妖们把人鱼一条一条地带进仁的壳里，智一边安慰他们，一边跟他们讲着事情的经过。
等人鱼们全部进到仁的壳里，巴斯也点清了“武器”的数量，交易成功！
眼看天就要黑了，天上又要刮起大风来，悠悠和小灵妖们赶紧爬上仁的壳，跟巴斯挥了挥手，飘向远方。
等他们走远了，走到连水晶宫都看不到了，赶紧把人鱼们放回水里跟他们的家人团聚。贝贝一下冲进妈妈的怀抱，激动得哭了起来，流出了彩色的珍珠。
族长把这些彩色的珍珠放在一起，送给了悠悠和小灵妖们，说道，“谢谢你们的帮助，这些彩色的珍珠是送给你们的礼物。人鱼伤心的眼泪是白色的珍珠，高兴的眼泪是彩色的珍珠。那些坏人们只知道让我们哭，然后收集我们的珍珠卖钱，却不知道彩色的珍珠才是最贵的。”
悠悠看了一眼正在哭泣的贝贝，发现她的眼泪里，除了彩色的珍珠，还有白色的珍珠。
“你的妈妈回来了，你不高兴吗？为什么还这么难过？”智轻轻拍了拍贝贝的肩膀，奇怪地问道。
“我的妈妈回来了，我很高兴。”贝贝擦了一把眼泪，难过地说道，“可是我爸爸还在水晶宫。我爸爸受了很重的伤，他本来想利用装死，趁渔人们把他抬出去的时候，抢走巴斯的钥匙，把大家救出去的。可是现在……”
“贝贝，不要哭，”族长说道，“咱们一定要把剩下的族人都救回来！”他说着朝人鱼们说道，“一会儿咱们就去水晶宫探探路，如果他们守卫少了，咱们就冲进去！”
“对！冲进去！”人鱼们大声地喊道。
“我们被抓的时候，都是被渔人们用麻袋装起来，然后被带到密室里，出来的时候也是一样，所以根本看不到密室的路。”贝贝妈妈着急地说道。“现在咱们既没有好的武器，又不认路，怎么救人呢？何况如果没有巴斯的钥匙，是没有办法打开密室的大门的。这可怎么办才好？”

The waves of the water swung like a pendulum. The people in crystal palace could feel it greatly. Buzz nearly fell but Yoyo had quick enough reactions and saved him.
Buzz’s jaw fell off his face. He was so surprised that he couldn’t speak.“gaafshabda” he spluttered in amazement. He then turned into a big smile. He said，“Good， good. I must have the lot!”
“Ok. You can have the lot.” Yoyo said with a smile.“However， your mermaids are pretty average.”
“Don’t you worry. How about if I catch more， I will give you them.” Buzz said with a smile.
The reason Yoyo said this was to make sure that Buzz wasn’t hiding anything.“Ok. We will do the trade and if you do have more， please save them for us.”
Everyone then went to the back to the yard of sand. Ren started doing his sarcastic spell and ever so slowly， Ren started growing bigger and wider and higher and stronger until he had covered up the whole yard.
As the demons were unloading the ‘Advanced weapons’， Buzz’s henchmen were also unloading the mermaids. As they went by， they smiled because what they seek is in their hands now.
Buzz’s henchmen all started to make sure that there was no broken ‘weapons’. They would pick one up very gently in hope that they don’t ring a bell. As this was happening， Zhi was trying to comfort the mermaids. He told them their plan and the recent events.
Until all the mermaids were successfully loaded in Ren’s shell and the weapons were in Buzz’s hands， Buzz knew that it was trade accomplished.
As soon as it was night， Yoyo knew that it was time to go. As the currents started going stronger， Yoyo and friends climbed into Ren’s shell said good bye and sailed away.
Until Yoyo and friends sailed far enough， they quickly released mermaids， all of the mermaids started crying loudly. Bella quickly swam to meet her mother and hugged her dearly. She started to cry rainbow pearls.
The chief quickly gathered the pearls and handed them to Yoyo， he said，“Here take this， these are rainbow pearls. Sad tears are white pearls and happy tears are rainbow pearls. The fishermen only know how to get white pearls but mermaids can make rainbow pearls. These are worth way more.”
Yoyo looked at Bella. He noticed rainbow tears and white tears?
“Your mum is with you now. Why are you still showing emotional distress?” Zhi said as she patted Bella’s shoulder.
“My mum is back and I am happy.” Bella said wile wiping away some tears.“But my dad is still at the crystal palace. My dad’s plan was to act dead so he could steal the key from the Buzz when he was going to get lifted out of the water and throw them the key. This way， the mermaids can be freed. However， the mermaids got freed and my dad is still in there.”
“Bella， don’t cry.” The mayor said.“We will rescue the residents. Tonight， if there aren’t any guards， we will emboscada.(Ambush)”
“Yes， we emboscada.” Chanted the crowd.
“When we got captured in big sack， we got carried away into the chamber. The whole sack was dark so we could not seewhere we were going.” Bella’s mum said with worried voice.“Besides， we have no powerful weapons， our whole defense has lack of sleep and we don’t know where the chamber is. Even if we knew where it is， we still don’t the key.”
