Trade with Sophia - 3 times]: Congratulations on getting the fifth, sixth, and seventh trade with Sophia.

[Note 1]: Because of the autonomous space-time protection mechanism of the universe, it is required that the long space-time transition must be a coordinated solution that conforms to the laws of physics, which means that when your fifth transaction with Sophia is completed, you will not be able to make a sixth transaction for the next three months. The seventh transaction is the same as above.

"I didn't expect that after being promoted to the king level, I was able to win three transactions with Sophia at one time, and I don't know if it was due to good luck or after the system upgrade, the fishing mechanism has changed.

Well, it should be both, right?

However, this sixth transaction will not be possible again until three months after the completion of the fifth transaction, which is a bit of a pity, but it would be interesting if it could be done three times in a row. ”

While muttering to himself, Jiang Bo's heart moved, and he clicked into the fifth transaction.

[Fifth Deal with Sophia]: Sophia from the ruins, it seems that she is in trouble again, she is calling you, begging you to show up, at this time, as long as you are willing to help her, you can get her favor and reward.

[Excuse me, would you like to answer the call from Sophia?]

[Yes/No?]

Without hesitation, Jiang Bo directly chose 'yes'.

As usual, this time Jiang Bo's gaze quickly shifted to the fishing area, and at the same time, the [Super God Projector] silently activated, establishing a super three-dimensional passage to the ruins for him.

Soon after, Jiang Bo entered the passage, traveled through time and space, and descended on the ruins again.

After the magnificent time and space passage of light and shadow disappeared, Jiang Bo's feet stepped on the solid ruined land, and his gaze was fixed on a sexy white-haired woman with a bumpy figure and an extremely beautiful face.

It had been about eight months since the last time we met, which was not too long or too short, but Jiang Bo felt a more mature aura from Sophia's body.

Her face, which originally looked a little green pheasant, has become contoured and angular at this moment, and it was already a good figure before, but now it is wrapped in a dark gauze skirt, slender and tall, there is no lack of grace and tightness, very mature and sexy, and charming.

"Mr. Chasers, I'm finally meeting you again......" However, Sophia's voice was still as sweet as ever, and when facing Jiang Bo, she was still like a little girl, very excited and happy.

"Long time no see. Jiang Bo smiled slightly, and his eyes lit up, if Sophia Jiang Bo, who used to wear a military uniform and looked heroic and beautiful, could give her a score of 97.

But now, I'm afraid I have to add two more points to be appropriate.

At this moment, Sophia's figure and face are impeccable, and although the cold cream Jiang Bo has seen before has different styles, they are both peak-level beauties.

It's so beautiful, it's not a loss to be a woman who can make the dog system repeatedly establish transactions...... Jiang Bo said secretly in his heart.

Sophia hurriedly replied, "Yes, I haven't seen you for almost seven years, and during this time, I will recite your name several times almost every day, but I don't dare to trouble you at will...... It's great to see you again!"

"Then why are you praying to me this time?" Jiang Bo said quietly, but he was secretly thinking in his heart, thinking about the ruins for seven years, no wonder Sophia looked more mature.

Sophia crossed her hands in front of her and said, "To tell you the truth, in the past seven years, I have gathered a group of people with the supplies you gave me, and after several repeated setbacks, I finally led my team to stand up.

At present, we have found an Yixun Garden, which has a complete ecological circulation system and complete energy supporting facilities.

However, after a few years of operation, we found a big problem, and that was the lack of fuel......"

Jiang Bo bowed slightly, and did not interject to make any comments, but waited for Sophia to continue.

Sophia: "There is a huge nuclear fusion reactor in the garden, although the raw materials for fusion can be used to make the energy generated by the reactor run for hundreds or even thousands of years, but before the disaster broke out, the alliance had already transferred the excess fuel stored in the garden.

By the time we found it five years ago, the fuel in it had only lasted less than three years, and now that two years have passed, if we don't get fuel to replenish it, it won't last more than a year.

So...... Mr. Chasers, I want to trade you for a batch of fusion fuel, is that okay?"

As soon as Sophia's words fell, a prompt popped up in front of Jiang Bo's eyes.

[Sophia officially makes a trade request to you, and the transaction content has the following three items, but you can only choose one of them]

[Option 1: Graphene Printing Device, Option 2: Anti-Gravity Ship Wreckage, Option 3: Stunning Maid from the Ruins]

[Please continue to communicate with Sophia according to the thoughts in your mind.] 】

This time was different from the previous ones, the previous four times, Sophia basically asked for food or medical supplies, but this time, she directly wanted to get nuclear fusion fuel from Jiang Bo.

But the problem is, he doesn't have any fuel for nuclear fusion, he doesn't have it!

There was a little helplessness and anxiety in his heart, but Jiang Bo's face remained calm, he looked at Sophia and asked, "What is the form of the nuclear fusion reactor in Yixun Garden, deuterium-tritium, or deuterium-3, or helium-3 and helium-3?"

From the words that Sophia had just confided, Jiang Bo could determine that the nuclear fusion reactor in her Yixun Garden was ninety percent light nuclear fusion.

If it's heavy nuclear fusion, you can just burn rocks, and it's everywhere, so there's no need to worry about fusion fuel.

So obviously, it's not heavy nuclear fusion.

Sophia hurriedly replied: "The nuclear fusion in the Yixun Garden is the second generation, and it can carry out both deuterium-helium-3 nuclear fusion and deuterium-tritium nuclear fusion.

However, the decay period of tritium is too short, with an average of only a dozen years, which is difficult to preserve, and it is relatively complicated to prepare.

I heard a scholar in my team say that before the disaster, the alliance had tritium-making technology with good efficiency, but after the disaster, many of the technologies were lost.

Therefore, we can only use deuterium and helium-3 as fuels for the reaction. ”

Jiang Bo bowed slightly, and Sophia said that there was no problem.

It is often said that a breakthrough in nuclear fusion technology means that there can be an infinite amount of energy, and this is true.

However, it is not realistic to have unlimited and inexpensive tritium.

Because deuterium, which is commonly known as heavy hydrogen, is very, very much found in seawater.

But tritium is basically very rare in nature, because the half-life is only 12.5 years, and after it is produced, it will soon decay into another substance.

The common experimental preparation method on earth is to enrich lithium with neutrons to enrich and produce tritium, but the efficiency is average.

As a result, the international price of tritium has always been not very cheap, with an average of hundreds of millions of soft coins per kilogram, which is much more expensive than fullerene, graphene and even gold.
