At present, the "golden stone" made by Mel and others is only a half-finished product, not the ultimate form in "Earth and Wind".

According to Mel, not only are there some steps in the forging process that cannot be repaired, but there are also several undecipherable raw materials that are missing.

Of course, this experiment did not have much practical benefit to Yandong's development except for burning money, and it also did not allow Mel's Sky Battleship to fly immediately.

However, after the loss, Xia Feng found a blind spot.

....

Although this basketball-sized "source stone crystal" cannot play a role in the development of science and technology for the time being, it is not completely useless for him personally.

At present, his black and white twin has entered the second stage, and the last time he triggered black power was in Yanyang Town outside Fengyang City, at the cost of the thousands of finished source stones stored in the town.

According to Hemer's last inspection of him, in order to trigger the second stage of black and white twins, at least 5,000 finished source stones or the equivalent amount of natural source stone bushes are required as consumables.

However, it was impossible for him to carry 5,000 Source Stones with him, because that was too much, at least several large suitcases.

And now, the energy contained in this "Source Stone Crystal" is exactly more than the energy of 5,000 Source Stones, that is to say, as long as he carries this "basketball" with him, he will meet the conditions for drawing out black energy at any time, so it should be understood correctly.

Subsequently, the idea did get professional buy-in from Hemer.

Inside the office.

Hemmer explained calmly.

"This source stone crystal has undergone a qualitative change in energy density, but it is still within the acceptable range of black and white twins, or in other words, this sublimated energy is more compatible."

Xia Feng nodded.

"That's good, at least it's not in vain, it's always a bit of gain."

Hearing his words, Mel exaggeratedly hugged the metal box tightly.

"Hey, what are you going to do, don't try to fight with my baby."

"I don't have violent tendencies, you think I'm willing to fight."

Mel stared warily at the summer breeze.

"That's not for sure, now that you have this thing, you're going to mess around again."

Xia Feng cried and laughed helplessly.

"Okay, since you cherish it so much, take it back to the laboratory and lock it up, I'll ask Lao Pu to make another one according to the experimental procedures, grit your teeth, bleed, and put tens of thousands of source stones into it."

Hearing Xia Feng's words, Mel pursed his lips and finally let go of the metal box.

"Forget it, anyway, as long as you master this process, those source stones are originally yours, so you can use them however you like."

......

The experiment with the "golden stone" is over.

The experiment cost a lot of manpower and money, and the results can only be described as gains and losses, however, in addition to the material aspects, there are other thought-provoking gains.

Since the experiment can be successful, it also means that the record in "The Earth and the Wind" is not scribbled, but true.

From this, it can be further speculated that except for the "golden stone", all the things recorded in the book are the products of the real appearance of this world, including technology, spells, and the spiritual world of people at that time.

There is no doubt that the era depicted in the book is far more technologically advanced than the current era, even to an unimaginable extent.

So, what is the reason for the demise of such a powerful civilization?

And why did the author of this book pass down this information?

.....

The office fell silent, and Pu and Mel left, but Hemer was the only one who remained.

For some reason, Hemer's mood has been inexplicably low, including the professional explanation of the experiment just now, and he has always been indifferent.

Xia Feng carefully placed the metal box on the desk underneath.

"It's pretty heavy."

Hemmer walked over to a nearby chair and sat down.

"Be careful, the metal box has the function of isolating the source stone substance, and it is best not to open it easily in the presence of ordinary people."

"Yes, I see."

After saying this necessary exhortation, Hemmer lowered his head slightly and sighed.

"Summer Breeze, we haven't seen each other for almost a year since we separated from Victoria."

Xia Feng replied softly.

"It's not that long, it's just over half a year."

Hemmer was clearly not obsessed with time, and her voice was deep and leisurely.

"During this time, Yandong has changed quite a lot, and it can be seen that you have put in a lot of effort."

"yes, that's what I have to do."

"You have done a great job, uniting the infected, helping each other, and winning the status of being recognized by the world by winning hearts and minds, which can be called a miracle."

For some reason, Xia Feng felt that Hemer didn't mean to praise him.

"Hemer, what's wrong with you?"

Hemmer kept his head slightly bowed, and a lost voice came out of his mouth.

"Xia Feng, you did a good job, but in my opinion, I'm afraid these are meaningless, you should understand what I'm talking about."

Hearing Hemer's words, Xia Feng was not surprised.

"Yes, I understand."

"According to Mr. Kane, your ore disease has worsened to the point where you need to use SIV to maintain it."

Xia Feng knew that the SIV that Hemmer was talking about was the new drug that Dr. Kane was giving him.

"Yes, yes."

Hemmer looked up and cast his gaze on Xia Feng's face.

"Xia Feng, do you know that this drug is used for severe patients with uncontrolled ore disease infection, and in theory, this kind of person generally does not live for 1 year."

Xia Feng was stunned for a moment, but soon, his expression changed to relief.

"Heh, 1 year, it seems shorter than I thought."

In a somewhat heavy atmosphere, Hemmer did not utter any more cruel words.

Pushing down her glasses, her voice came to its senses.

"Ifrit's ore disease is also showing signs of deterioration, so this time I'm going to bring her back to Colombia to be systematically suppressed by the ore disease, and from now on, I won't allow her to use the power of the fire demon again."

Hearing this, Xia Feng's optimistic expression finally collapsed a little.

"It's my fault, it's all because I asked Ifrit to use the power of the Fire Demon a lot in the past 1 year, which caused ......."

"Nope."

Hemmer interrupted Summer Wind's self-reproach.

"The reason for Ifrit's deterioration is unclear, and it can't be confirmed that it is related to the frequent use of the power of fire, so you don't have to say that, and ......."

"And what."

"And the degree of infection in Ifrit is obviously not as serious as yours."

.....

The subtext of Hemer's last sentence is cold, and it is also a kind of rational cruelty.

Xia Feng understood what she was thinking.

Ifrit's infection is showing signs of deterioration, but it is not as severe as he came, that is, at the current development, he will undoubtedly die before Ifrit.

Hemmer really can't blame a dying friend.

Or, at this moment, the most self-blaming person should be Hemer herself, because she is a doctor, but she can't save the "patient" she cares about.
