Dongfang Qiming took the secret realm key, Muyang and Honda Shinnosuke also came over, checked for a while, and all shook their heads.

Although it is indeed a spatial key, it cannot be used in this palace. The way to get out of trouble is only to pass the final test, and then open the palace gate and leave.

But it took their elder brother and the third son sixty years to successfully clear the customs.

"Little soldier, it looks like you're going to be with our old three."

Dongfang Qiming returned the secret realm key to Nie Bing, shaking his head and sighing.

"Master, I'll try to complete the task, maybe I can clear the customs."

Nie Bing put away the key and was not discouraged. He is even very confident in his own technical means.

"Completion of the mission?"

Dongfang Qiming looked at Nie Bing, shook his head with a wry smile and said, "It's too difficult." That task is simply not something that a grandmaster can accomplish. ”

Nie Bing was slightly stunned.

"Yes, little soldier, I don't know if the one who came out of this mission is a pervert?"

Shinnosuke Honda pinched his orchid finger and said coquettishly: "I've done a lot of analysis over the years, and the exam questions from this damn enemy are all random, and there are no hints at all." However, I have summarized the general types.

There are roughly three types; The first is to specify a topic, such as giving you a theme, so that you can forge machinery according to your requirements; This is the easiest. The second is any question, give you a bunch of materials, play forging at will, and then evaluate by the system, this difficulty is high, because you don't know the standard of system evaluation, say you can do it, say you can't do it, you can't do it.

And then it's the most perverted third, randomly selecting a random topic to disassemble the equipment as required. Generally speaking, disassembling is the easiest, but its rules can drive you crazy. For example, if you are asked to disassemble a tiny core screw separately within the specified time, but it cannot destroy the overall mechanical operation, can you do it? That's the difficulty. ”

“……”

After listening carefully to Shinnosuke Honda's analysis, Nie Bing roughly understood the difficulty of this task.

In fact, they are all seemingly simple basic forging machinery topics on the surface, but with some strange requirements and restrictions, the difficulty is multiplied.

However, no matter how difficult it is, he has to try.

You can't stay here and see off the three old men one by one, right? He still has a lot of things to do out there. There are still many people waiting for him to take care of, how can he be submissive here?

"Master, no matter how difficult it is, I still want to try. Otherwise, I will not be reconciled. ”

Nie Bing straightened his waist and his voice was firm.

Dongfang Qiming looked at Nie Bing for a long time, and finally sighed helplessly: "Sure enough, it was handed over by that kid from Horton, and it was all a temper that didn't die in the heart of the Yellow River." Forget it, just go. Be prepared, though. Once the mission fails, it can be as short as four or five months, and it will not be able to come out for more than ten years. When the time comes, don't be lonely. ”

As he spoke, he patted Nie Bing on the shoulder as a sign of encouragement.

"Little soldiers, brother, there are a lot of films about our country here, I have passed half of them to you, you can relieve your boredom when you can't come out."

Honda Shinnosuke found a stack of large-capacity chips out of nowhere and threw a wink at Nie Bing.

Nie Bing waved his hand again and again to refuse, and there was a chill in his heart.

"Save half of the food. Take this one. ”

Mu Yang unceremoniously gave Nie Bing a chip, and then ordered him to keep half of the food.

Who knows when Nie Bing will come out? It's always a good idea to plan ahead.

Regarding Muyang's character, Nie Bing is still trustworthy. Although he is a man of few words, he has an honest heart.

He took out more than half of the food in his backpack, leaving only a small part, and then put the chip away, walked to a very smooth bark under the giant tree, and reached out and pressed it.

Snort, the power of Yuan Energy penetrated, the light and shadow flickered, and Nie Bing disappeared in place.

Watching Nie Bing enter the mission space, Dongfang Qiming was stunned, and Shinnosuke Honda beside him touched the other party's arm and said, "What, worried?" It's not dangerous, at most it's just a few years. What are you afraid of? ”

Dongfang Qiming didn't answer, just turned his head to look at the wrinkles in the corners of Honda Shinnosuke's eyes, and sighed.

"Hey, what do you mean? Do you think I'm old? ”

Shinnosuke Honda said loudly as if he had been stepped on his tail.

"He was afraid that it would take too long and no one would send him to the end."

Muyang seemed to see through Dongfang Qiming's thoughts, but in fact, he didn't think so in his heart.

If Nie Bing hadn't appeared, maybe the three of them wouldn't have felt time flies, but when they saw this young man coming in, and he was also Dongfang Qiming's apprentice, their mood was different. I feel that time is like an arrow, and it is really a generation urging a generation of old.

"Hopefully, the creeps will really be able to complete the mission. He's too young to stay here for the rest of his life. ”

Dongfang Qiming subconsciously looked at Mu Yang beside him, and coincidentally, Mu Yang also looked at him, the eyes of the two met in mid-air, and a smile suddenly appeared on Mu Yang's cold face.

"You're not afraid of death?"

Mu Yang said a sentence without a head.

"Hahaha, I have a grandson, what am I afraid of? It's ...... you."

Dongfang Qiming laughed and looked at Muyang.

"I have chips."

Mu Yang interrupted.

"Chips?"

Dongfang Qiming was stunned for a moment, then looked at Muyang, and the two laughed at the same time.

……

The strong smell of grass and trees enveloped Nie Bing, and in front of him was a circular room with a diameter of more than twenty meters, which felt like a tree hole, a green light and shadow.

There was a workbench in front of it, and on it was a rusty old machine, buzzing at the moment.

Just looking like an old man bending over in the twilight with a crutch, trembling up the mountain beam, the parts of his body are about to fall from violent coughing and trembling.

Even Nie Bing walked lightly, for fear that the extra vibration would make this old machine fall apart.

Ding dong! In the mission scene design, the trialists drove mountain off-road vehicles, speeding on rugged mountain roads, rushing to the disaster area, and doing their best to rebuild their homes for the people. But then there was a fierce beast chasing, and the parts of the mountain off-road mechanical vehicle were old and needed to be repaired.

The trialist must replace the parts in the designated position within five minutes.

A beam of light split into more than a hundred rays and fell on the old machine, illuminating the parts that needed to be replaced.

Ding dong! Requirements: The mountain mechanical vehicle cannot be stopped, the power unit must be kept in normal operation, the original wire position structure can not be damaged, and only the carat Xuan steel can be replaced. Does the trialist accept the quest?

"Dismantling the stripping topic? Or is it a disassembly strip that is superimposed for a limited time in motion? I'm in the pit! ”

After listening to the requirements of the task exam questions, Nie Bing knew that he had been shot.

No docking, no stopping of the power unit, or complete the task within the five-minute limit. This is already very demanding.

But what is even more demanding is that without destroying the original wire structure and without stopping the power plant, the Kra Xuan steel is simply ridiculous.

The Yuan Neng wire is directly built on the carrier of the carat steel, and the replacement of the carat steel will inevitably touch the Yuan energy wire, and look at the area required to be replaced, more than 60%.

This is definitely a problem that goes straight to the grandparents.
