On the Seven Towers

Xiao Chen clasped his hands behind his back and looked up. The clouds here were very low, and they were only about two hundred meters away from the ground. He said to the others: "This is the trial level that the king called, this city wall." The canyon was completely blocked.

According to the king, this is a strange world. There are turbulences from space cracks in the clouds above. It is very dangerous to fly up, so the levels cannot be crossed and can only be broken through one level at a time. The trial questions that will appear in each level are different. No one ever knows what the theme of the next trial will be. Only through trials will this door be opened. "Xiao Chen explained to Farrell and other great blacksmiths.

"That is to say, our blacksmith must pass the trial before the team can move forward, right?" Farrell said.

"That's right. And our task is to always pay attention to the surroundings to see if the false god will appear here." Xiao Chen said.

"What if it sees us and is afraid to show up?" Farrell asked.

"Then let's take the Forging Tower." Xiao Chen glanced at the two great forgers of the Fire Crystal Family and said, "But I don't think it will let go of this opportunity."

"Then I still hope it appears. This thing is a threat to the entire dwarf kingdom. Although I now belong to the Tower of China, this is my hometown after all." Farrell said.

"I will try my best." Xiao Chen nodded and said to Luo Ling and many other experts behind him: "Let's get ready for battle and let our spiritual servants come out first so as not to be caught off guard."

Farrell brought Mucia and other great blacksmiths to the door. The sound of talking immediately came from around the gate. They could not tell where the sound came from. They only felt that the person seemed to be close to their ears: "Triers, here you have to try to solve the first puzzle. On the gate There is a stone slab. When the slab is opened, you will see a keyhole. You need to use the tools next to the slab to create a key within one hour, and then open the lock. If you do not create this lock within the specified time. If you fail to unlock the key after inserting the key, you must exit this trial."

The stone slab that the voice was talking about was less than two meters away from the door. When the voice finished speaking, the stone slab made a rumbling sound and moved to one side from its original position, revealing a small space behind it. There was indeed a keyhole in there, but nothing else. And a line of magic text appeared just above the stone slab. It was a countdown, and the one-hour countdown started from this time.

"Just open the lock like this? Isn't this something that a young thief can do? Can we also be tested on such a question?" Master Lascano of the Fire Crystal Family said.

"It won't be that simple. Didn't you hear some strange noises here?" Farrell said as he moved closer to the keyhole to check. "Damn it, the structure inside this lock is moving!"

Xiao Chen and others had summoned the spirit attendants at this time. When he heard Farrell's voice, he asked others to pay attention to the surrounding situation, and then he and Luo Ling walked to the keyhole.

He and Luo Ling each released their own mental power and began to explore the structure of the lock cylinder.

Xiao Chen fumbled for about a minute, and then said: "This lock cylinder is divided into five layers from the outside to the inside, just like five rings arranged one by one. They all rotate around the central axis where the key is inserted, but the speed They are all different. You have to make the key into a certain shape, and then calculate the speed of the five lock cylinders. At a specific moment, insert the key at an extremely fast speed so that the five lock cylinders can be jammed at the same time. , and then open the door."

Midros, another great forger of the Fire Crystal Family, asked: "We only need to observe the shape of the gaps in each layer, and then insert the keys into them layer by layer, locking one lock cylinder at a time. Can't we do it? ”

Xiao Chen waved his hand and said: "No, no, it's far from that simple. I observed the structure other than the lock cylinder. These five lock cylinders must keep rotating at the same time or not moving at the same time. Once some lock cylinders move, some lock cylinders will not move. , the lock's self-destruction device will be activated, and high-heat magic energy will be generated inside to completely melt the lock core, in which case the trial will fail."

"This is crazy! How is it possible to do something like this?" Lascano said.

"This is a test set by the ancient saints. Pay attention to the tone of your words." Farrell said.

Lascano was stunned for a moment, and then said: "No matter what, this is still too difficult!"

Even Mucia said: "I think it is very difficult to make such a thing. Just predicting the trajectory of the lock cylinder is a big problem."

Xiao Chen said: "My mental power can help you detect the size and structure of each keyhole, and then project it. You only need to make molds according to this projection. And Luo Ling can help you calculate the speed of their operation. If you get the same time for the five cores, you should be able to pass the test with an agility master like Evelin."

Farrell shook his head slowly and said: "This is a test given to blacksmiths by the dwarf ancestors. Although it can be easily solved with your method. But in this holy land of predecessors, I still want to pass it in our own way. I The seniors can pass this level, there is no reason for us to be blocked here. Don’t worry, my sons can all stand on their own, and Mucia is also very talented, so these problems will not trouble us.”

"Yes. Chairman Xiao. Dad is right. We can do it. All those math classes in the Tower of China were not learned in vain. My brother is very good at calculating these things. He can also calculate the rotation speed." Farrell's eldest son said.

"Is that so."

Xiao Chen felt a very determined attitude from Farrell and his son. He realized that this was not just a task to complete a level. For these dwarf forgers, it was also their inheritance and honor. "

"Xiao Chen. Please let us complete our trial." Farrell said solemnly.

"Okay, I agree." Xiao Chen nodded.

Farrell started working immediately. He asked his eldest son to use a thin wire to reach into the keyhole to measure the structure inside. He held a board on the side and outlined the structure of the keyhole. His youngest son was observing the speed of the keyhole and calculating the time when the five keyholes overlapped. As for the other three great forgers such as Musia, they were assigned to the tool area on the side to make fire and iron and prepare for forging.

"Are you acting on impulse? What if they..." Mei Tiantian asked.

"Not really." Xiao Chen smiled and said, "If they say so, I don't trust them, how can they be called companions?"

"At least they are on the right path now." Luo Ling said.

"Even we can't guarantee that we will pass every trial. Everyone makes mistakes." Xiao Chen patted the thick wall in front of him and smiled: "But even if we fail, we still have cannons. "
