面对悠悠的问题，老树精慢慢解释道，“在很久很久以前，创世之神在不同的空间里塑造了不同的世界，比如神界，魔界，鬼界，怪界，妖界，人界……你属于人界，而我属于妖界。近年来他发现你在的这个世界不太平，人界自私，好斗，凶狠……这令他很不满意，所以他打算在天空之路再建造另一个世界----‘彩云之巅’。”
“那么这个世界的人们都会迁往‘彩云之巅’吗？这个世界又会变成什么样子？”悠悠好奇地问道。
“这个……”老树精叹了一口气，说到，“‘彩云之巅’只会留下这个世界里最好的人类，而剩下的将会和这个世界一起被遗弃。到那时候，太阳将不再为这个世界贡献热源，月亮也不再出现，这个世界将会进入一片黑暗静寂。”
“什么！？”悠悠突然想到了他的爸爸妈妈，他们虽然常常批评他，但是悠悠知道这种批评是爱他的体现，特别在他生病的时候，是爸爸妈妈一直陪着他，在他失望难过的时候，也是他们一直陪在他的身旁……他又想到了他的妹妹依依，虽然她常常惹他生气，但是每当依依有什么好东西的时候，她第一个愿意分享的人永远是他……还有他的同学们，虽然他们会嘲笑他，但是他们也是他的队友，他的伙伴，一起分享在学校里的每一寸时光，或欢乐，或悲伤，一起度过……
这个世界不能毁灭！一定要救他们，一定要让他们全部回到这个世界！
“‘彩云之巅’在哪里？我要去找创世之神，我要告诉他这个世界不光只有自私，好斗，凶狠，还有善良，关爱，互助，拼搏，他不能随便遗弃这个世界！”悠悠攥了攥拳，下定决心，朗声问道，“我该怎么做才能找到我的家人，找到其他所有人，并且把他们都带回来？”
“把所有人找到并带回来？就你一个人？这太难了！我刚才说过，‘彩云之巅’是在天空之路的最上端。你需要找到天空之路，然后经过各种世界，才能到达‘彩云之巅’。你要知道，天空之路是很难被找到的，就算被你找到了，你自己一个人也很难走出天空之路的各种世界。那些世界里的人，有的很残忍，也许会想吃了你，有的很温柔，但也许不会让你走……”老树精看了一眼失望难过的悠悠，沉吟了一下，说道，“好吧……如果你决定要去的话，我倒是有个主意，或许能帮得上你，但是不知道你愿意吗？”
“愿意，”悠悠大声说道，“只要能让所有人都回来，不管多艰难，我做什么都愿意！”
老树精看着悠悠慢慢说道，“悠悠，想要找到天空之路，必须寻求妖界的帮助。我虽然属于妖界，但是年龄太大了，实在帮不了你多少，可是我的这根拐杖可以帮助你找到动物灵妖。如果你能克服心理的恐惧，可以向灵妖们寻求帮助，相信他们一定会帮助你的。”老树精说着，把手里的拐杖递给悠悠，继续说道，“你握紧我的拐杖，朝它指的方向一直往前走，就会走到灵妖的世界……”话音未落，老树精慢慢消失在阳光下，遥远地传来他苍老低沉的声音，“天空之路很难走，悠悠，祝你一切顺利。”。

The tree demon replied，“A millennia ago， Exodus created lots of worlds in the universe， for example， God world， ghost world， devil world， demon world and human world. You are part of the human world and I am part of the demon world. Over these recent years the human world doesn’t have any peace， instead people are selfish， mean and not caring. This made Exodus unsatisfied， so Exodus is planning to make a new world at the top of the Silver Road of Heaven called The Heavenly World.”
“Does that mean that all of the people in this world are moving to The Heavenly World. What will this world turn into after all of the people left this world?” Yoyo asked curiously.
“Well…” the tree demon let a big sigh， and said，“The Heavenly World will only keep the perfect people and kick out the imperfection people. At that time， the sun and the moon was not in sight so the earth was a big round pitch black ball floating in the middle of space.”
“What!?” Yoyo suddenly remembered about his parents. Although they sometimes correct his behavior， he knew that his parents are doing this for his good. Especially when he was sick， his parents were always the ones who helped him feel well. Then he also remembered about his little sister Yiyi. Although she always makes Yoyo mad， when she got something she likes， Yoyo was the first person she was willing to give her share. Finally， he remembered about his friends. Although they would sometimes tease at him， they are still his best buddies.
Yoyo was determined that he should save the world， save the people， and bring everybody back to this world.
“Where is the Heavenly World located? I need to find Exodus， I need to tell him that this world has more than mean， nasty， bossy people， this world also has nice， caring and hardworking people. He can’t just take our world and he also doesn’t have the right to destroy it.” Said Yoyo to the tree demon，“Could you please tell me how to save the world from its destruction?”
The tree demon said in a surprisingly，“Save the world from Exodus? Just you? That is near impossible! As I said， the Heavenly World is at the top of the Silver Road of Heaven. First of all， you must find the Silver Road of Heaven. Secondly， you have to go through various worlds， and then you can find the Heavenly World. You need to know， the Silver Road of Heaven is really hard to find， and even if you find the world， it would be merely impossible for you to get out. People from the various worlds you go through might be mean， and might try to eat you. Some might be kind but not let you go.”
The tree demon looked at Yoyo’s sad face， sighed，“However， if you insist， I have a plan.”
“I insist，” Yoyo said in a confident voice，“as long as I can save the world and everybody that was taken by Exodus， no matter how tough it gets， I will do it!
The tree demon looked at Yoyo and said in a really weak voice，“Yoyo， if you want to find the Silver Road of Heaven， you must seek help from the demon world. Although I belong to the demon world， I am too old to help you accomplish this mission. If you are able to conquer your fears， I can lend you my walking stick which can show you the way to the demon world. I am sure that the demons will help you. Hold the walking stick tight and it will eventually take you to the demon world.” The tree demon vanished into thin air and said in a ghostly voice，“the Silver Road of Heaven is really dangerous to walk through. GOOD LUCK YOYO.”
