In the yard, everyone was wide-eyed and open-mouthed in astonishment.

Whether it was Zhang Guocheng, Xiaolin, Wang Yu, or the others, they really couldn't believe that the scene just now could be so majestic and grand.

A scene as terrifying as a sea of flames suddenly appeared in the sky.

The key point was, from afar, everyone saw that the range of this sea of fire possibly reached a diameter of several kilometers.

Bear in mind, the range of the Hiroshima atomic bomb was only a four-kilometer diameter area.

And just now, the all-encompassing sea of fire technique Lu Li displayed also reached a diameter of several kilometers?

This left Zhang Guocheng, Xiaolin, Wang Yu, and everyone else so shocked that their souls seemed to have left their bodies.

Thus, even though Lu Li had finished displaying his "ultimate technique," the people on the scene were still in shock, looking at the empty high sky.

They all thought Lu Li's destructive power was already comparable to a small nuclear bomb!

In fact, only Lu Li himself knew that the magnificent sea of flames he just displayed was all for show.

Not to mention comparing it to a small nuclear bomb, it wasn't even as powerful as a slightly longer burning open flame.

Unless he targeted a hydrogen-rich area or a gas station, it wouldn't unleash terrifying power.

Why was the sea of flames he displayed considered all for show?

Firstly, everyone was far away and didn't actually know how wide the fire's range was.

There were no reference points in the high sky.

It led people to mistakenly believe the fire's coverage reached a diameter of several kilometers.

In fact, it was only 1.23 kilometers.

Lu Li's spiritual power release currently could reach only this far.

Of course, spiritual power was released from him as the center, reaching in all directions this far.

Simply put, the range of the spiritual power release was a radius of 1.23 kilometers.

Secondly, his current maximum disturbance component of spiritual power is only about ten kilograms.

Just now, using spiritual power, Lu Li manipulated the free hydrogen in the air, spreading it over that large area, then used spiritual power to ignite it, which made the scene look grand.

Actually, it only burned for a moment and had no significant power.

This wasn't because the explosive power of ten kilograms of hydrogen was weak.

In fact, the power unleashed by ten kilograms of hydrogen could reach that of a powerful fuel-air explosive bomb with 280 kilograms of TNT.

The premise is that it's gathered together, not spread out that widely.

No one had any idea that Lu Li was showing off, thinking he was genuinely impressive, hence their shock.

After being in shock for half a day, Zhang Guocheng suddenly came to his senses, turned his head sharply to the side, and stammered, "Mr. Lu... Mr. Lu, is... is this the maximum power of your superpower?"

Xiaolin, Wang Yu, and the others just woke up from their shock, all looking toward Lu Li with deep reverence in their eyes.

Lu Li was actually almost completely drained of spiritual power, mentally exhausted, but he still acted as if it was nothing, boasting, "Didn't I just say? I only showed a portion of my power for you to see, otherwise, I'm afraid if I go full strength, even I can't manage the situation."

Wha... what?

The terrifying scene just now was only partially displaying strength?

Zhang Guocheng couldn't help but take a sharp breath!

Wang Yu was even more mentally shaken to the core!

Xiaolin and everyone else were almost scared to death hearing this.

Oh my god, even partial strength looked almost comparable to a small nuclear bomb.

If you go all out, wouldn't you destroy a city in an instant?

At this moment, everyone realized that their previous assessment of Lu Li's danger level being "disaster" might have been underestimated!

...

Back inside the house.

Everyone dared not look directly at Lu Li!

Including Zhang Guocheng; he even seemed somewhat deferential sitting there.

It was conceivable how fearful everyone was after understanding Lu Li's "real strength."

Seeing his bluff succeed, Lu Li knew that for the foreseeable future, these people shouldn't have any untoward thoughts about him.

Intimidating these people was just one of the purposes of meeting Zhang Guocheng today.

Lu Li had more important things to do.

He looked at the silent crowd, and finally, his gaze fell on Zhang Guocheng, "Mr. Zhang, I contacted you today through Wang Yu because there's something I'd like to ask for your help with."

If Zhang Guocheng had heard this before understanding Lu Li's strength, he would surely inquire what the matter was, then propose some conditions for an equivalent exchange or even take advantage of Lu Li.

But now, Zhang Guocheng didn't feel he had the right to negotiate any terms.

He quickly responded, "Mr. Lu, whatever you need, just say it. As long as it's within my capability, I will definitely get it done for you as soon as possible."

Lu Li, satisfied with his attitude, replied cheerfully, "It's not a major issue, I'm just preparing to research and develop some things and currently lack some insulating materials, and I'd like your help in acquiring some."

Zhang Guocheng was surprised, "Just some insulating materials? Can't they be bought on the market?"

Lu Li frankly said, "No, they can't be bought on the market. It's said that only the aerospace sector in our country currently has them."

"The aerospace side huh..." Zhang Guocheng frowned slightly, "I haven't had much interaction with that area."

Lu Li thought it was impossible to obtain it, and was about to say that it was fine if they couldn't get it.

Unexpectedly, Zhang Guocheng's next words were, "Since you've asked, I'll do whatever it takes to help you get it."

Without much past interaction, would he really help him acquire the materials?

Lu Li certainly understood what Zhang Guocheng really meant by this statement.

Simply put, if he hadn't shown such potential earlier, even if Zhang Guocheng had the ability to help, he might not have been willing to assist.

After all, dealing with the Aerospace side, with whom he had little relation, might incur huge favors.

But things had changed; after witnessing the grand "value" Lu Li presented, Zhang Guocheng wanted to strengthen ties, thus was willing to help him get the thermal insulation material at all costs.

Even though Lu Li understood the other party's intentions, he still said, "Thank you."

Zhang Guocheng asked, "What type of thermal insulation material were you referring to? I'll make a call to ask."

Lu Li replied directly, "Ultra-light carbon-based micro-ablative heat-resistant material."

"Alright, please wait a moment." Zhang Guocheng stood up, took out a phone from his pocket—something resembling an antique red phone—and said, "I'll make a call outside."

Lu Li nodded and said, "Okay, thank you for your help, Mr. Zhang."

Zhang Guocheng said, "No trouble at all," and walked straight outside.

Having exhausted a significant amount of Spiritual Power earlier, as soon as the other party left, Lu Li immediately closed his eyes to relax.

Sitting not far away, Wang Yu, Xiaolin, and a few others wanted to approach Lu Li and establish connections.

But seeing Lu Li close his eyes, they dared not disturb him and could only keep glancing over from a distance.

After waiting for about four to five minutes,

Zhang Guocheng returned from outside, holding the phone.

He approached Lu Li and respectfully said, "Mr. Lu, the Aerospace side has agreed to provide you with the materials, but Mr. Zou... uh, Mr. Zou would like to have a brief chat with you. Would you have the chance to speak with him?"

Lu Li had long since eavesdropped on the phone conversation with his super hearing capabilities.

He knew who was on the other end of the line.

It was the direct person in charge of deciding whether to provide him with the thermal insulation material.

Even though the other party had agreed, if Lu Li did not answer the call, it would seem impolite.

"Alright, hand me the phone." Lu Li took the specially designed red antique phone and placed it to his ear, saying, "Mr. Zou, thank you for agreeing to this favor."

"Ha-ha, it's a minor matter." A senior male voice came from the phone, it was Mr. Zou, who still seemed unaware of Lu Li's true identity, asking, "The ultra-light carbon-based micro-ablative heat-resistant material, we can allocate some to you, but I want to know, what are you going to do with such high-end aerospace materials?"

Lu Li thought for a moment, then decided to speak honestly, "I'm working on developing a high-speed engine, and ordinary thermal insulation materials might not suffice, so I asked Mr. Zhang to contact you."

Mr. Zou, upon hearing this, became interested, "Oh? How high-speed is the engine going to be that requires ultra-light carbon-based micro-ablative heat-resistant material?"

Lu Li replied, "Estimated to be around one hundred and fifty thousand revolutions per minute."

"One hundred and fifty thousand revolutions per minute?" Mr. Zou immediately asked, "Are you referring to an internal combustion engine?"

Lu Li nodded and said, "Yes."

Mr. Zou inhaled slightly, saying, "Mr. Lu, please don't take offense at my questioning, are you truly certain about developing an internal combustion engine at one hundred and fifty thousand revolutions per minute?"

Lu Li affirmed, "Previously, I had someone do a 3D model, and the simulated speed was indeed one hundred and fifty thousand revolutions per minute."

Mr. Zou seemed to be quite shocked and remained silent for quite some time.

About a minute later, Mr. Zou took a deep breath and said, "Mr. Lu, may I make a bold request?"

Lu Li responded, "Please go ahead."

Mr. Zou requested, "I would like to send two aerospace engine designers to take a look at your engine structure. Rest assured, we're not trying to steal your patent; I just want to verify some things before discussing potential business matters, like supplying your developed engine to the Aerospace department."

Normally, the aerospace field does not use internal combustion engines as a power source.

The principle of an internal combustion engine is to convert internal energy to mechanical energy, with internal energy generated from fuel combustion.

Fuel combustion requires oxygen, which is not available in space, making internal combustion engines unsuitable for space.

Moreover, space is a vacuum environment, lacking the medium required for internal combustion engines to operate, like air, and there is no oxygen.

Thus, internal combustion engines cannot work properly in space and are not suitable for spaceships or other spacecraft.

For this reason, Lu Li found Mr. Zou's request rather puzzling when he heard it.

Nevertheless, he knew the other party must have a reason for making the request.

The more significant point was, if they truly reached a business agreement, there would be a major client once the engine was developed!

Aerospace is known for high expenditures, isn't it?

If they became a client, it would mean a continuous stream of money!

With this in mind, Lu Li agreed without hesitation, "Alright, please send them over."

...

By the time Lu Li returned to Longda Machinery, it was already past one in the afternoon.

In the laboratory, Lu Li looked at Peng Erping and Engineer Fu, along with several designers, announcing the good news, "I've secured the ultra-light carbon-based micro-ablative heat-resistant material. Expectedly, tomorrow the Aerospace department will send people over to discuss terms with us. I hope you'll be able to assist me in negotiations with Aerospace because, in that area, I'm truly inexperienced."

Ah?

You left this morning and returned in the afternoon to tell us that you've obtained the ultra-light carbon-based micro-ablative heat-resistant material, a highly classified material?

Peng He Ping and Engineer Fu, along with the other designers, were all taken aback, each wondering just how impressive his connections were.
