In contrast, to realize one more is easier than a single Dao to achieve Da Luo Jinxian, and there will be more combat methods.

However, if a single Dao can achieve Da Luo Jinxian, although the combat method is single, it will undoubtedly be much more powerful.

But there is a prerequisite, this doorway must be good enough and will not be restrained, otherwise it is better to have more means.

At the moment when Ye Feng focused on cultivation, a knock on the door came in.

Bang bang bang!

The night wind slowly closed his work, his eyes slowly opened, and he exhaled deeply, his complexion revealed a hint of discomfort.

It’s not good to be an emperor. There are too many messy things, no matter how bad they are.

"Didn't I say yes, can't I interrupt when I practice?"

Some fearful words came from outside the door, "The emperor, the emperor, Mr. Mao Gong said there is an emergency military situation to report."

Now that the power has been collected, and the arrival of Mr. Xu Mao, Ye Feng's anger has disappeared a bit, and he doesn't bother to care about it anymore. "Let Mr. come in."

Creak!

The door opened, and Mr. Xu Mao walked in with a person.

The person Xu Maogong brought was a middle-aged man who was about 30 years old and looked good, but there was some distance between his behavior and the nobles. In particular, he had some smell of motor oil on his body, although he looked very good. After washing carefully, there is still some residue.

"This is?" Ye Feng looked at the person who seemed to have seen him, but he was not familiar with it.

"Emperor, this is the technician you brought back." Xu Maogong explained somewhat unexpectedly, obviously it was unexpected that Ye Feng didn't even know him.

"No wonder I feel a little familiar." Ye Feng was relieved.

There are more than a hundred people brought back from the earth, and it is not realistic to say that all of them know each other. After bringing them back, those who have little contact will have no impression, but if they have all been met, they will naturally have some impressions.

"Didn't your husband say that there is military intelligence? Is he related to military intelligence?" Ye Feng had some questions.

"Yes, the emperor." Xu Mao justified and continued, "If you want to come to the emperor, I don't know about him, Xiao Yun, you can introduce yourself to the emperor."

"Good lord!" Xiao Yun arched his hand and turned to look at Ye Feng, his expression immediately became restrained, his expression was obviously a little unnatural, "The emperor, this is the case, the villain has a plan, and he has a plan for your majesty to attack the world. Great use."

"Oh?" Ye Feng looked at him with interest, and looked at him, obviously unbelieving.

Many ministers and celestial generals have no better way. Can a technician like him have a way?

However, since he was recommended by Xu Maogong, Ye Feng was also prepared to give him a chance to elaborate.

"Let's talk about it." Ye Feng motioned.

Seeing Ye Feng's expression, the technician's expression became more tense, but it still didn't stutter.

This shows that the psychological quality is pretty good.

"The emperor, the villain feels that to attack a mortal army, your majesty can use more technological means." Xiao Yun said sternly.

"In terms of technological weapons, we have been developing and upgrading them all the time, is this your idea?" Ye Feng became a little impatient.

What Ye Feng said, but Xiao Yun was more calm than before, "The emperor, you can use it in wars, but not only weapons, but also transportation tools. If you want to come to your majesty, do you know the subway?"

"Naturally." The night breeze responded. As the crossing party, he brought these technicians back, so it's natural that he didn't know the subway.

"We can build subways for Gu Meng, no, for countries all over the world." Xiao Yun said proudly.

"Repair the subway?" Ye Feng's eyes narrowed slightly, as if he understood a little, but he didn't rush to interject, "Go on."

"According to the purpose!" Xiao Yun handed his hand, seeing that Ye Feng became more sure of himself, and he became more daring, "The emperor, the villain heard that our army is attacking Gu Meng. The problem is time. We must conquer the entire territory within seven days. In terms of strength, it is still easy to solve, but not in terms of speed.

However, what if we build a subway in Gumeng? Use the subway to carry soldiers to various places, so that your majesty's blossoming style of play can be realized.

More advanced weapons, absolutely crushed, can be quickly decided, and after being defeated, they will be evacuated very quickly.

In seven days, as long as the command is strong enough, it is enough to lay down and return, and then wholeheartedly welcome the battle of God. "

Hearing this, Ye Feng first nodded in his heart. Using the subway to transport his troops, he could reach behind the enemy unconsciously.

But randomly shook his head, "This method is very good, but you seem to have overlooked a point. The speed of the subway is not as fast as you think. Most of the speeds are below 100 kilometers per hour, and the ancient Meng is lower than the huge speed. It is unrealistic to complete all evacuation within seven days."

Xiao Yun seemed to know that Yefeng would have this doubt, and calmly said: "The emperor, I have also considered this point. Our subway, strictly speaking, can be called an underground high-speed rail, and it will use EMUs. The speed of 300 is no problem. of."

"Is it three hundred per hour?" Ye Feng thought, "If there is such a speed, it is still feasible, but there will be some problems in the specific implementation, such as how to prevent the ancient Mongolian people from discovering the construction process? Especially the station entrance."

Xiao Yun didn't answer any more, because he could manage this.

Xu Maogong took a step forward and said: "The emperor, on this point, the old ministers are still relatively easy to handle. The ancient Mongolian land is vast, but there are not many people, so the population is scattered. Our subway station can choose to be in a sparsely populated place. , And send a small number of troops to accompany it, which can guarantee nothing."

Ye Feng thought carefully, this method is feasible, but the project is huge, and the funding and manpower will be huge investment.

At the same time, it also needs very detailed control, and there can be no mistakes. Once discovered, all previous efforts will be discarded. In this way, I have to think twice.

However, Ye Feng was never an indecisive person, his thoughts were merely considerations of feasibility, nothing else.

After thinking about it, Ye Feng asked the core of the question: "Can EMUs be made?"

Xiao Yun arched his hands and said: "The emperor, the villain and two friends have been engaged in the manufacturing and design of EMUs before they came, and they are guaranteed to be manufactured.

"Okay, you immediately start to manufacture the EMU. If necessary, you can ask Mr. Maogong for help to build the EMU. I have a great reward!" Ye Feng's figure walking back and forth stopped and made up his mind.

Xiao Yun's expression was joyful at first, followed by a little hesitation, as if he wanted to talk but stopped.

"What? What else do you have?" Ye Feng asked.

After a pause, he restrained the fear in his heart, and finally opened his mouth: "The emperor, the villain's income is pretty good, even without this credit, he is still free of worry."

"You mean not to reward?" Ye Feng asked deliberately.

In fact, he knew that this was not the case. He had seen through Xiao Yun's thoughts. This guy had another plan, but he didn't know the details.
