Let's start by analyzing the sun

Next up.

The highlight of this demonstration: the actual machine test.

All the talk beforehand was just empty words.

To convince the general, they had to see the burning effect of the high-efficiency fuel with their own eyes.

Cheng Han smiled and said, "Your Excellency, I have prepared two small arcane-tech combustion engines. One uses ordinary fuel, and the other is filled with high-efficiency fuel for comparison."

Jian Wanli's tone contained a hint of urgency: "Good!"

"Snap!"

Cheng Han snapped his fingers.

"Whoosh! Whoosh!"

Two Spirit Oak Demon's branches immediately extended, holding two identical combustion engines and gently placing them in front of the general.

Two other tree spirits each held a wooden bucket with their branches, the buckets containing two different colors of fuel.

One fuel was black, emitting a slight earthy smell.

This was ordinary fuel.

The other fuel was amber, with a strange fishy smell.

This was naturally high-efficiency fuel.

Jian Wanli watched intently as the Spirit Oak Demon used its branches to unscrew a metal cap and pour the two fuels into the wooden fuel tanks.

By the way.

Since the Wan Hao people are very good at using plants, most of the parts of this combustion engine are made of plants.

For example, the cylinder block is made by cultivating "Rock Wood". The strength of this wood is not inferior to steel, but its density is only 50% higher than water.

The unique "cultivation" process can easily produce complex-shaped parts, which can then be processed later.

In short, the Wan Hao people's skill in playing with plants has reached a very high level.

Only core parts such as pistons, cylinders, and crankshafts are made of alloy.

A few seconds later.

The fuel was added.

At this time.

A Spirit Oak Demon made a strange movement.

Dozens of branches shot out, weaving into a protective net to cover the two combustion engines.

Jian Wanli was stunned for a moment: "This is…"

Cheng Han explained with a smile: "The combustion of high-efficiency fuel is too violent, and the combustion engine may not be able to withstand it, and may explode."

The role of the protective net was obviously to prevent parts from flying around.

Jian Wanli nodded lightly.

Cheng Han instructed the tree spirit: "Ignite!"

Soon.

The combustion engine was started.

"Buzz~ Buzz~"

This was the sound made by the machine with ordinary fuel.

"Bang! Bang!"

This was the effect of high-efficiency fuel. Not only was the sound more powerful, but the machine vibrated more violently, and the flywheel speed was much faster.

The difference between the two combustion engines was too obvious.

Jian Wanli said softly: "The flywheel on the left combustion engine rotated 52 times per second, and the one on the right rotated 73 times, an increase of almost 40%."

This Profound Overseer actually counted the rotation speed of the flywheel with his naked eyes.

And at this point.

It was enough to prove that the effectiveness of high-efficiency fuel was far stronger than ordinary fuel.

After a while.

"Bang! Crack!"

A strange noise suddenly came from inside the right combustion engine.

A gap at the connection between the cylinder block and the cylinder head suddenly widened, and a bright light emerged from it.

The next second.

"Boom!"

The combustion engine exploded.

In this instant.

The protective net above suddenly tightened, firmly wrapping the machine and preventing parts from flying around.

Cheng Han explained: "The structure of the combustion engine is designed according to the standards of ordinary fuel. If high-efficiency fuel is used, the engine body must be redesigned."

Jian Wanli nodded: "Civilian combustion engines can continue to use ordinary fuel to save costs. Military equipment such as war eagles do need to be redesigned."

From this sentence, it can be seen that this Profound Overseer must have spent a lot of time studying the arcane-tech industrial system in private.

Cheng Han deeply agreed with this: "This is also my plan."

Jian Wanli asked the main point: "Are you afraid to conduct large-scale experiments because you are worried about the existence of internal spies in the war zone?"

Cheng Han nodded: "This is a battlefield, and high-efficiency fuel is of great importance. I must be as cautious as possible."

If war eagles are used for testing, as long as they fly around in the sky above the Heavenly Lotus, the enemy will definitely notice the problem unless they are blind.

In case the enemy sends out a Profound Overseer-level powerhouse, or even a God-level powerhouse, to forcibly carry out a beheading operation, wouldn't he lose his life unjustly?

Jian Wanli asked again: "Did you specifically ask me to come here to see the God General through me?"

Cheng Han nodded again: "The Youmiao Realm is not a safe test site, and the experiment must be returned to the Void Wind Realm for testing."

The "Banyan Realm Gate" for entering and exiting the alien world is controlled by the God General, and this matter must be reported to the God General. However, only the Profound Overseer has the authority to directly contact the God General.

Jian Wanli pondered for a moment and said readily: "Come back to the Middle Court with me, and I will take you to see the God General."

*

Half an hour later.

Middle Court.

Inside a hidden stone hall.

"Buzz~"

The sound of the arcane array operating continued to echo.

Large swaths of illusory flames danced in the empty stone hall.

The flames swept over the body without any unusual sensations, as if it were just an illusion.

But touching it with the eyes inexplicably felt hot all over, as if roasting in a fire, which was no different from real fire.

Such a strange contrast made Cheng Han startled.

He also faintly sensed a trace of extremely subtle divine power.

Without a doubt.

This was the power of a God General's divine imprint projected remotely through the arcane array.

After a while.

The flames in the hall rapidly contracted into a ball, and then transformed into a lifelike figure of a middle-aged man, completely indistinguishable from a real person.

This person had an extremely peculiar feature - the top of his head seemed to have no hair, only hair-like slender flames dancing.

This scene was truly impressive.

Jian Wanli respectfully bowed: "Greetings, General!"

Cheng Han immediately followed suit.

The middle-aged man's gaze first swept over Jian Wanli, ignoring him completely, and then looked at Cheng Han, saying with interest: "Cheng Han, right? Lan Yun has mentioned you to me several times."

The "Lan Yun" in this sentence obviously refers to the Lan Yun God General.

Cheng Han quickly replied: "Yes, General!"

Jian Wanli secretly clicked his tongue.

A high-ranking God General repeatedly mentioning a Profound Practitioner is definitely not ordinary regard.

The middle-aged man introduced himself with a smile: "I am the 'Zhu Rong' God General, but many people secretly like to call me the 'Renaming God General'."

Cheng Han was a little confused.

What the hell is the Renaming God General?

Jian Wanli's face twitched imperceptibly.

The Zhu Rong God General smiled: "All the God Generals in this world have heard about the battle of the War Eagle Legion. Lan Yun is right, the War Eagle is a groundbreaking weapon."

The next second.

Cheng Han finally knew the reason for the word "Renaming".

The Zhu Rong God General changed the subject: "But I think the name Cheng Han is too ordinary. Why not change it to War Eagle?"

After asking.

The flames on the God General's head were obviously much more intense.

Cheng Han felt a sense of disorder in the wind.

To change someone's name as soon as they meet, what kind of messy problem is this?

His heart moved, and he suddenly understood the God General's scheme.

There was no other reason.

As long as he agreed to change his name to "War Eagle", it would be equivalent to defecting to the Zhu Rong God General's camp in disguise.

Cheng Han didn't want to change his name, so he put on a look of being in a dilemma.

He was a member of the Qinghan Arcane Palace, and strictly speaking, he should be in the Lan Yun God General's faction.

And the reason why he was able to lead the War Eagle Legion to descend on the war zone as a beginner Profound Practitioner was also thanks to the care of the Lan Yun God General.

For both emotional and rational reasons, he couldn't agree to change his name.

The Zhu Rong God General didn't force him, but smiled: "Alright! If I force you to change your name, I'm afraid that woman Lan Yun will come to my door tomorrow."

With this sentence, the flames on his head returned to their original state.

This General looked at the general and directly ordered: "Rename the three Heavenly Lotus in the Dongli War Zone to War Eagle Lotus Island, Sea Eagle Lotus Island, and Cloud Eagle Lotus Island."

The God General paused and casually found a reason: "The War Eagle and Sea Eagle deserve this honor for their contributions."

Jian Wanli immediately responded: "Yes!"

The corner of Cheng Han's mouth twitched.

No wonder he was called the Renaming God General. He really felt uncomfortable if he didn't change a name.

He knew very well that there was also a little bit of careful thought in it.

This God General obviously saw that the War Eagle had great potential, so he would try to "蹭 (cèng - freeload/mooch)" a little fame, and also show a little goodwill.

The Zhu Rong God General then got to the point: "What's the matter with you contacting me this time?"

Jian Wanli took half a step forward and said quickly: "Reporting to the General, the matter is like this…"

The general, like pouring beans out of a bamboo tube, told the whole story of the high-efficiency fuel from beginning to end.

As he narrated, the Zhu Rong God General's face changed repeatedly, and the flames on his head became more and more intense.

In the end, it turned into a raging fire.

"…General, that's the way things are. Commander Cheng hopes to return to the Qinghan Arcane Palace to conduct experiments."

Jian Wanli ended this long speech with this sentence.

The Zhu Rong God General turned his head and stared at Cheng Han, asking seriously: "Are you really not considering changing your name to 'War Eagle'?"

He paused and directly threw out a series of benefits: "I can appoint you as a special envoy of the God General, and I can also do my best to help you become a Profound Overseer!"

Very obviously.

The God General fully understood the great significance of high-efficiency fuel and couldn't help but extend an "olive branch" again.

Jian Wanli's eyes widened when he heard this, and an obvious look of envy appeared on his old face.

He had worked hard for more than eight hundred years, and had gone through countless hardships, before he finally advanced to the Profound Overseer.

But the young Profound Practitioner next to him actually received the God General's personal promise and had a super opportunity to be "recommended" to the Profound Overseer.

How could this not make people feel unbalanced?
