"You're going to pass!"

The team shouted this sentence, announcing the end of the inspection.

Several Red Armor soldiers immediately removed the obstacle and made way for the road.

Xie Qing, a servant of the Three Spirit Leaf level, politely thanked him first, and then drove the crystal energy car and slowly drove towards the woods in front of him.

It's not that I don't want to be fast.

But don't dare to be fast.

Previously, the steward of the living hall had specially told them several times that the Spirit Oak Demon was not a good-tempered creature, so he tried to be as light as possible so as not to provoke them.

"Whew~"

A cold wind blows.

The branches and leaves of the Spirit Oak Demon swayed slightly, and it looked as if it had fallen into a deep sleep.

Xie Qing couldn't help but curse in his heart: "It's a ghost place to really step on a horse!" ”

Because the servant felt strongly that he seemed to be stared at by countless pairs of eyes.

Such a strange feeling made the hairs on his back stand on end, and even the hands holding the steering wheel couldn't help but tremble.

Xie Qing was frightened, and muttered in a low voice: "I'm afraid that thing is true." ”

The "incident" in his mouth was a rumor in the Xuan Palace.

As early as more than a month ago, the envoy used amazing methods on the Spirit Oak Demon Forest, creating an earth-shattering spiritual tide.

I heard that the next day, a middle-level mystic who had mastered the mystical method of the wood spirit system wanted to study the spirit oak demon, but was instead captured by the spirit oak demon design.

Many of the minions did not believe this rumor.

Because the combat power of the Spirit Oak Demon is obviously inferior to that of the Xuanshi, and the middle-level Xuanshi casts the Wood Spirit Mysterious Method, and his power is definitely stronger than that of the Spirit Oak Demon.

Many people believe in another rumor, thousands of spirit oak demons have undergone extremely strange changes after being baptized by the spirit tide, and their strength has increased a lot.

Xie Qing is now inclined to believe that the latter should be the truth.

That's when it happened.

The unexpected happened.

"Whoa!"

The sound of friction sounded intensively.

Hundreds of branches swept in from all directions.

After an instant.

The crystal car became entangled in the branches and lifted up slightly, and the four wheels could only spin in the air, unable to advance a single cent.

Xie Qing screamed in fright: "Mom! ”

He immediately remembered the steward's words, could not shout, and hurriedly closed his mouth tightly.

The next moment.

An even more astonishing sight emerged.

Because dozens of branches are quickly interspersed in the air, and they are actually put together into a line of text - the envoy is working, you are not allowed to go over and disturb!

Xie Qing couldn't believe his eyes.

Oh, my God!

Can the spirit oak still write?

I've never heard of such a thing!

Xie Qing plucked up his courage and stammered, "I'...... I have been instructed to deliver ...... to the envoy Send a batch of important parts! ”

After all that is said.

Only then did he realize that he was stupid?

Spirit Oak Demon is not human, it cannot understand human speech at all, and must use extraordinary means to communicate with it.

However.

The unexpected happened.

"Whoosh! Sou! ”

More than a dozen branches quickly stretched out to the rear of the vehicle, and looking in the rearview mirror, they seemed to be inspecting the parts contained in the wooden box.

A second later.

"Bang!"

With a muffled sound.

The crystal car was lowered back to the ground, and the wheels propelled the vehicle slowly forward.

Hundreds of branches shrank back in the blink of an eye, as if the scene was just an illusion.

Obviously.

The Spirit Oak Demon let it go.

Xie Qing's heart jumped "poof", and a thought popped up in his mind: "Is this the special envoy trained by the envoy?" ”

This distraction.

The crystal car deflected to the side, and the front of the car crashed into a spirit oak.

"Whoosh! Sou! ”

A few branches immediately leaned over and put on a solemn warning posture.

Xie Qing hurriedly spun the steering wheel and controlled the crystal energy car back to the center of the road.

The branches left immediately.

Xie Qing breathed a sigh of relief and muttered, "It's amazing! ”

It's a pun.

On the one hand, it is a sigh that the spirit oak demon has become a spirit.

On the other hand, it is to admire the Lord's means to train such a short-tempered creature.

*

Not much.

Xie Qing finally saw Envoy Cheng.

The servant stopped the crystal energy car, got out of the car as fast as he could, and saluted, and said respectfully, "Your Excellency, a new batch of parts has been delivered." ”

Before Xie Qing could raise his head, he heard a gentle voice: "Thank you for your hard work!" ”

Flattered, he replied, "It's not hard! It's my greatest pleasure to serve you! It's also a servant's job! ”

"Click! Click! ”

A slight sound came.

Xie Qing instinctively heard the sound, and a trace of amazement flashed in his eyes.

I saw a rather large sand table, carved into the shape of a spirit leaf, on which there was a miniature rail car, driving along a circular track.

I have to say.

The model is simply extremely detailed, with details exactly like a real rail car.

At a glance, it was clear that this thing must have come from the hands of a master craftsman with extremely high craftsmanship, and it would never be possible to make it without one or two hundred gold coins.

Xie Qing instantly realized that this was the gadget that the envoy had recently indulged in, and it was also a model of the rail car in the Tai'an Little Spirit Realm.

Of course.

This is inevitably suspicious of nonsense.

Is it really appropriate to fiddle with this kind of little thing all day long, and let the Tiangong Hall spend time and effort to build a model?

But for geniuses, even the palace master remained silent.

Never mind!

Let him go!

Cheng Han glanced at the servant and asked with a smile, "What do you think of the speed of the rail car if the speed of the rail car is faster than that of the Xuanshi?" ”

Xie Qing was stunned for a moment, and hurriedly replied: "This is a very good idea. ”

The servant thought for a moment and said boldly: "Today's rail cars are not much faster than bicycles, and there have been many derailments over the years.

"It is conceivable that once the speed of the vehicle is increased to the flight speed of Lord Xuanshi, the frequency of accidents will definitely increase many times."

Cheng Han said with a smile: "It makes sense. ”

He said seriously: "But I think that as long as we insist on continuous improvement, the speed of the rail car in the future will definitely be much faster than that of Xuanshi, and the safety will definitely be guaranteed." ”

Cheng Han silently recited in his heart: Why can't there be high-speed rail in this world? The transformation of the world by the traverser starts with the high-speed rail!

Xie Qing was a little unexpected.

Faster than Xuanshi?

That's an exaggeration!

Railcars have been around for more than a thousand years, and the speed has always been like this.

But the servant did not dare to refute, but cleverly echoed: "Your eyes have seen farther than we do, and I believe that this day will come after all." ”

Cheng Han nodded lightly: "Yes!" ”

He smiled again and said, "I'm tired of you today, you can go back first." ”

As soon as the words fell.

"Whoosh! Sou! ”

The branches of the canopy came to him, rolled up the wooden box, and placed it on the ground.

Xie Qing saluted respectfully again and left in the crystal energy car.

Tranquility has returned to the woods.

"Click! Click! ”

The miniature rail cars are still spinning in circles.

Cheng Han looked at the model and muttered: "The gray crystal machinery is too bulky, and increasing the power will cause the weight to rise sharply, which is not suitable for high-speed rail power."

"However, the laws of the world are different, and we can't make electricity, so the only solution is to start with the internal combustion engine."

This has been the case for a while.

In the eyes of others, the genius envoy is addicted to mechanical gadgets and has a lot of fun.

In fact, he officially began the development of the world's first internal combustion engine.

That's what he's been thinking all along.

It's just that I didn't have time to implement it before.

Now that he has become a Xuanshi and has a certain amount of power in his hands, he decisively put it on the agenda.

Cheng Han made up his mind: "First set a five-year plan, get a high-power internal combustion engine, and then build a high-speed railway." ”

He looked up at the sky, and his gaze became deeper: "Powerful power can make machinery fly into the sky, ordinary people can fly faster than Xuanshi, this is the real revolutionary change!" ”

Once the airplane is officially introduced, not only the way of life, but also the way of warfare will undergo a huge change.

For the Wanhao clan as a whole, this is undoubtedly a good thing!

Cheng Han turned his head to look at the wooden box and ordered, "Open it!" ”

"Whoosh! Sou! ”

The branches rolled over, easily removed the wooden box, and then got the metal parts one by one.

Cheng Han buried his head and began to work.

An hour later.

A strange sound rang out.

"Boom! Rumble! ”

With a noisy and rhythmic pop, a strange-looking machine, a metal pipe on it spewed billowing black smoke.

It is the testing machine of the internal combustion engine.

Cheng Han looked surprised: "It's a success!" ”

Another dozen seconds passed.

"Bang!"

A strange sound suddenly came.

The testing machine came to a slow stop.

Cheng Han's surprise disappeared and was replaced by distress: "Although the experiment was initially successful, it still needs a long time to improve to have a practical type.

"Due to the obstacle of crystal energy technology, the internal combustion engine is a technology that has never been seen in this world, and the omniscient eye can't find much from the ocean of information, and the deduction efficiency is not high."

He sighed: "I'm too hard! ”

As a beginner-level mysticist, he is heartbroken for the future of the Wanhao clan!

Soon.

Cheng Han found a pen and paper and quickly wrote a letter:

"Mr. Craftsman,

"Today my experiment was successful for the first time, which proved my theory of the internal combustion engine, that the heat generated by combustion can produce powerful power.

"I'm sorry to inform you that you lost this game......"

*

Geumsan Palace.

At this moment.

The palace master, Yun Changshan, was reading a pile of letters quickly.

Many of the words and sentences in them really made it difficult for this Xuandu to understand.

But given that the writer of the letter was a great genius, the Cloud Palace Lord still read it patiently.

"Calorific value is a key indicator, and the higher the calorific value of the fuel, the more powerful the power can be ......"

Xuan Du muttered blankly: "What does calorific value mean, and what is power?" ”

"The internal combustion engine is a power conversion system, and the working process can be divided into four stages, namely inhalation, compression, work, exhaust ......"

Xuandu was completely stunned.

What the hell is this?

Obviously, I know every word on the letterhead, but when I connect it, I can't understand it at all.

The Cloud Palace Lord barely watched for a while and was forced to give up.

He shook his head and muttered, "Everyone else thinks that this kid is fooling around, but from his correspondence with the master craftsman, there seems to be a little doorway!" ”

That's when it happened.

A Xuan Shi walked over quickly and said respectfully, "Palace Master, the results of the Xuan Array Detection have come out." ”

The Cloud Palace Lord put down his letterhead: "Go and have a look." ”

Xuanshi immediately turned around and led the way.

A minute later.

In a stone hall.

Xuan Du saw that a rather large and strange illusion, with a radius of more than twenty meters, was suspended above a huge Xuan Array.

If you look closely, there are constantly streamers of light, flowing endlessly along the veins in the illusion.

Xuan Shi's tone was full of surprise: "Thousands of Spirit Oak Demons have established an incomparably complex network of roots, extending to a depth of five hundred meters or less.

"This 'Guiyuan Soul Exploration Array' shows that there are extremely mysterious and extraordinary fluctuations between the root systems, and it seems that there is some kind of communication with the Divine Banyan ......"

The man talked for a long time, and at the end of the day he exclaimed, "I'm sure that the envoy is studying a great mysticism. ”

Among them, "remarkable" is obviously a very high praise.

The Cloud Palace Lord stared at it for a few seconds, and said, "It's really interesting!" ”

He then chuckled: "The entire Xuan Palace thinks that this kid is not good at cultivating and tossing some inexplicable things, but in fact, this kid is busier than anyone else." ”

The palace master cleverly disguised a little, he didn't see what kind of experiment this was.

No way.

Even Xuandu is powerful when he is poor.

At the beginning, the Cloud Palace Lord used a secret method, but he failed to recognize the Lingyun Wansen Xuanyin, and even his name was secretly poked and poked to instruct his subordinates to find out.

For Cheng Han's experiment, he only judged that it was related to the Spirit Wansen Xuanyin.

The Cloud Palace Lord looked at a Xuan Master and resolutely ordered: "Pei Zhangdian, in the future, if there is a need for special envoys of Cheng, they must be given priority!" ”

According to the most simple logic, what the dignified Xuandu can't understand must be something beyond imagination.

That being the case, of course, it is necessary to strongly support it.

Pei Zhangdian immediately responded: "Yes!" ”

The surrounding group of Xuanshi immediately understood that from this moment on, the status of Special Envoy Cheng in the Xuangong Palace had risen a lot compared to before.

This time is not short.
