The last thousand kilometers away from the Tai'an Little Spirit Realm, this airship formation began to frequently encounter patrolling warhawks.

The Heavenly Passage inside the Spirit Branch, with a diameter of more than two kilometers, and an extraordinarily large internal space, is very suitable for patrolling with warhawks.

Cheng Han knows this, and it is precisely because of himself.

These are most likely the two deputy heads of the Red Armor Palace, and it is estimated that the boss will soon arrive in the Tai'an Small Spirit Realm, so he will make such an arrangement.

This is for security reasons.

There is also a hint of flattery.

"Hum~"

The vibration of the warhawk's engine, each time wafting from afar.

In front of all the windows of every airship, there must be a crowd of people.

Faces with all kinds of looks, staring closely at the warhawks flying in formation, and watching them fly away in formation.

The sound of discussion continued to come into Cheng Han's ears.

"The eagle flies so fast!"

"Yes, the airship is as slow as a snail compared to the warhawk."

"How do these big guys fly? Could it be that the warriors are sitting in it, shaking the big fan with their hands? Isn't this a swollen wrist? ”

When Cheng Han heard this, the corners of his mouth couldn't help twitching.

Hand crank?!

What a lot of imagination!

He also knew that now that the war eagle had just begun to deploy to various small spirit realms, and a large number of civilians had never seen the war eagle, it was not surprising to have such a ridiculous guess.

Others took the initiative to correct it.

"I don't need to shake it, I heard that a new type of machine for drinking brown oil has been installed, and it is much smaller than the gray crystal machine."

"What a machine for drinking brown oil? It's called the 'Como Internal Combustion Engine'! ”

A few seconds later.

The warhawk flew a little closer and saw more clearly.

The topic of discussion among the passengers has changed.

"What's under the wings of the warhawk?"

"It's like there's a boat hanging on one side."

"There are still a few warriors sitting in the boat!"

The corners of Cheng Han's mouth twitched again.

Tai'an was the first to obtain the small spirit realm of war eagles, and the black cat had seen with his own eyes that under the wings of several war eagles on both sides, two warriors were hung on ropes each.

I didn't expect the Red Armor Army to be even better at playing, so they directly made a flying pod, and it was still a streamlined design with low wind resistance.

The Warhawks used for patrols are all two-seater models, and there are two people in the cabin, and three people in each of the pods on both sides, adding up to eight people.

】

Cheng Han watched the war eagle fly closer and closer, and couldn't help but think of the scene of "the third brother playing a motorcycle" in another time and space.

In a word.

Dute is a talent!

"Buzz!"

With a roar, the flock of war eagles swept past not far away.

Some of the fighters sitting in the pod even waved their hands at the airship.

This scene made the passengers cheer loudly.

All of a sudden.

The scene was very lively.

Cheng Han couldn't help but smile, and a thought suddenly popped up in his mind: "Maybe this is the change of the times!" ”

In the past, the soldiers of the Red Armor Army usually patrolled on bicycles, patrolling up to 200 kilometers a day, and only once a few days in a slightly farther position.

Now that it has been replaced by a war eagle, it can easily fly a thousand kilometers in two or three hours, and it can be patrolled back and forth several times a day.

Compare the two.

In the latter way, the efficiency is increased by a hundredfold.

Soon.

The warhawk is gone.

The passengers sighed again.

"If there are warhawks patrolling all the way, you won't have to worry about the safety of the airship in the future."

"Yes! The speed of the warhawk is so fast, in case the airship is in danger, it won't take long for the Red Armor soldiers to rush over. ”

Cheng Han's eyes flashed, and he replied in his heart: "It will be soon." ”

As the head of the Chijia Palace, he immediately started to plan: "The total length of the spiritual branches under the jurisdiction of the Xuan Palace is more than nine thousand two hundred kilometers, and there are a total of sixteen paths to the heavens.

"Based on this calculation, the total mileage of the patrol is close to 150,000 kilometers, and if one Warhawk is allocated for 100 kilometers, 1,500 will be enough.

"Considering rotation and spare, about 5,000 warhawks can cope with daily needs.

"As for the staffing aspect.

"According to the ratio of war eagles to personnel, only 20,000 Red Armor soldiers are needed, which is enough to protect this section of the spirit branch.

"By the way, the warhawk also needs corresponding maintenance personnel, almost three thousand people are enough."

Cheng Han smiled slightly: "At present, the soldiers stationed in the Spirit Branch of the Red Armor Palace, although some of them are sent to the battlefield, are still as high as 80,000 people.

"And once the warhawk is fully promoted, only more than 20,000 people will be enough, and the patrol efficiency will be far beyond the past.

"It's a revolution!"

After returning to the single cabin.

Cheng Han took out the communication weapon from the suitcase and sent the order, demanding that the deployment of the war eagle be completed in batches and times within half a month, and it would be fully converted into a war eagle patrol.

In other words, other Xuan masters are in charge of the palace, even if the plan is drawn up, it is difficult to carry it out.

Because this matter involves the coordination of multiple agencies, and the production of five thousand warhawks in half a month is not a simple matter.

But Cheng Han is in charge of the Demon Research Institute, and there is a large-scale Spirit Oak Demon Factory under his hands, as long as he gives a word.

A few seconds later.

The reply came: "Obey the orders of the Cheng Palm!" The Red Armor Hall will do its best to complete the mission! ”

At this moment.

Cheng Han's heart was full of a sense of achievement.

He's changing the world bit by bit!

And it will change the world completely!

*

Early the next morning.

The remaining distance to the Tai'an Little Spirit Realm is already less than a hundred kilometers.

Inside a single room.

Cheng Han stared at the pile full of drawings and exhaled: "It's finally done." ”

In the past few days, he deliberately accelerated the progress, and almost sleeplessly tried his best to draw, and finally completed a complete set of drawings for the new Warhawk engine.

This is an epoch-making new engine.

And the non-stop deduction day and night has also brought rich rewards.

For each completed part drawing, depending on the level of difficulty, you will receive as little as 100-200 proficiency points and as much as 500-600 proficiency points.

At the moment when the final design was finalized, the proficiency skyrocketed by more than 16,000 points.

This whole set of drawings adds up to more than 30,000 proficiency points, which is too much compared to the old internal combustion engine of the past!

This alone shows how significant a modern engine is.

The upgrade progress of the Omniscient Eye has subsequently reached 241122/500,000, which is almost half.

After a while.

Cheng Han suddenly felt something.

His mind moved.

Stars flashed in the sky.

A halo emerges.

On the picture in the center, a familiar figure suddenly appeared.

It was the Speaker of the Destruction Mission, Arthur.

This guy was running wildly in a dense forest, his body sweeping over one tree after another like green smoke, and his face was full of panic.

It can be seen that this guy seems to be being hunted down.

And there is a wilderness, and it is unlikely that the authorities are hunting it down.

So.

The answer is about to come out.

Cheng Han was stunned for a moment, and couldn't help laughing: "Arthur has defected from the Destruction Mission?" ”

Just the other day.

A Nether had a fight with the McCarran Oracle, and by the way, he engaged in a bit of discord and discredited Arthur in front of the Oracle.

He never expected that the effect would be so fast.

It was only a few days before Arthur actually defected.

Cheng Han was very proud in his heart: "In terms of engaging in conspiracy and tricks, I am really getting better and better!" ”

He then fell into a deep groan: "What to do with Arthur?" ”

He remembered the severed finger of the god's body, the ancient main god of the ruins who didn't know the name, and immediately had an idea in his mind:

"There is a high probability that there are corresponding clues in the major alien god organizations, maybe I can let Arthur do this."

The female warrior Qu Xiaoying is also a suitable candidate, but her strength is too low.

Arthur is a strong Xuanshi, and his use value is greater.

Besides.

Who thinks there are too many ghosts?

Cheng Han immediately made up his mind: "That's it!" ”

But.

The matter is urgent.

Judging by the current situation, Arthur estimated that he was in considerable danger.

This hapless speaker was mostly used as a scapegoat for the assassination failure by the divine envoy, and was directly sold to the Prayer Society, and he had to help.
