The room was silent for a long time, and finally Pandora broke the frozen atmosphere, cocked her nose, showed an expression of not wanting to care, looked at the old man of the lich and asked, "What are the few questions you want to calculate?"

"Whew—" The old man exhaled lightly, put his hand into his bosom, and pulled out a crumpled piece of papyrus with scribbled handwriting, "Well, it's all written on it, three of them." ”

Pandora glanced at it and cried out "Little bell!"

"Wang!" a dog barked, and a yellow shadow sprang out from under the desk, it was the golden retriever of the old man of the lich.

After scurrying out, the golden retriever looked at Pandora flatteringly, wagging his tail and sticking out his tongue, waiting for Pandora's order.

Pandora pointed to the papyrus in the Lich Old Man's hand and said, "Get it for me, little bell." ”

"Wow!"

The golden yellow dog barked twice in reply, and jumped up to the old man the lich, took the papyrus from the old man's hand, held it steadily, and jumped back to his desk.

Handing the papyrus to Pandora, Pandora casually touched the head of the golden retriever yellow dog, and the golden retriever yellow dog turned around excitedly several times in the same place, his tail wagging like a car wiper in a rainstorm, and his nose exhaled.

Pandora began to read the contents of the papyrus, and the old lich man looked at the excited golden retriever and his expression became a little strange, and he said to Pandora in a loud voice: "Hey, little girl, why are you ...... My dog is called Little Bell, I remember, he doesn't have that name, does he?"

"Brush!"

Pandora put down the papyrus she was looking at, glanced at the old lich and asked, "Is there anything wrong?" I remember that you promised to lend it to me for twenty days, and now it has only been seventeen days, and there are three days to go. And if you come and ask me questions again, the time will be extended. What my name is before I give you back the little bell, that's my freedom. ”

"But......" The old lich man tried to say something, but opened his mouth and said nothing.

Glancing at the golden retriever who was trying to please Pandora, the old lich man sighed lightly and exclaimed in a somewhat dejected voice, "Okay." ”

"Whoa!"

Pandora straightened her nose, grabbed the papyrus in satisfaction, and continued to look.

......

The other side.

Richard checked the facilities in the many rooms and made sure that they were all functioning properly to ensure that uranium-235 could be purified under the effect of the laser, and he breathed a sigh of relief and walked back to the main laboratory.

Sitting down at the circular lab table in the main lab, Richard took out the papyrus and laid it out, holding a quill dipped in ink, and began to write down complex formulas on it.

"Rustling ......"

At the end of the day, Richard substituted the values of the meters he saw during his inspection of many facilities into formulas and calculated them.

"Rustling ......"

After a few minutes, Richard put his quill aside and looked at the bottom of the papyrus, where there was a final number that had just been calculated—0.5125±0.0025.

This value represents the energy deficit in the current nuclear weapons research and manufacturing program.

Compared to the expected state, there is still about 50% of the energy short, and this is under the premise that the Truth Society's "Blood Alchemy" has successfully reduced the energy waste, and with the help of the energy of the ancient tree species of tin wood.

Before that, the difference was a few hundred percent.

As things stand, if nothing changes, it will take almost two years to produce enough weapons-grade enriched uranium and make nuclear weapons.

But after a year, the time for cooperation with the ancient tree Ximu will come, and the other party will leave, and then the time will have to be extended to three years later, or even longer.

Although he thinks that the ancient tree species Ximu is likely to make some mess before the cooperation time arrives, this is not 100% certain.

So now he only has two ways to solve the problem.

One is to use some methods to really "force" the ancient tree species Ximu, and then violently suppress it, forcing the other party to extend the cooperation time to two years later.

The other is to use other means to make up for the energy shortfall.

In both ways, he prefers the latter. "Forcing rebellion" against the ancient tree species of tin wood, not to mention moral immorality, after all, there is a risk, and there is no guarantee of 100% cooperation from the other party. In comparison, it is more guaranteed to use other means to make up for the energy shortage.

As for this method, he now has some ideas, that is, to learn from the ancient tree species Ximu to absorb from the void.

The ancient tree species of tin wood uses the special nature of its own life to absorb endless energy directly from the void. He doesn't have this ability, but he can use some spells to achieve results.

Admittedly, spells that could achieve their effects were rare, but they weren't non-existent, and he remembered that the Truth Society branch seemed to have a book about it, called ......

......

Two days later.

Truth Church Deland Branch, Conference Room.

At one end of the rectangular conference table, sat the steward Canon and the supervisor Rommel, Rommel was holding a white rabbit in his arms that was obviously fat, which looked to weigh more than ten pounds, and at the other end of the conference table sat Richard.

Rommel rubbed the long ears of the white rabbit with the fingers of his fingers, raised his eyes to look at Richard, and said slowly: "So, Wizard Richard, do you want to exchange the branch's Book of Void?"

"Yes. Richard nodded, the expression on his face not changing much.

"And the reason?" Rommel said, letting go of the white rabbit's long ears and scratching the white rabbit's head instead.

"Same as before. Richard spoke up, "For the research I've been here for." ”

Rommel stopped scratching the rabbit's head slightly, picked up the white rabbit's hands, placed them on the table like an ornament, and looked at Richard with a serious expression. After staring at it for about a second, he took a deep breath and said, "Wizard Richard, I remember we talked about this before, your research on matter and energy is a detour, and if you continue to work hard, there will be no results, so it's better to stop early." Before, I thought that after you exchanged the study of "Blood Alchemy", you would recognize this reality, but now it seems that you have fallen deeper and are ready to study the knowledge related to the void.

You must know that the knowledge related to the void, even the ancient wizards have not studied it thoroughly, and the knowledge that has been handed down is even rarer. It's almost impossible to try to make a breakthrough in your research with a broken record, so it's better to give up sooner. ”

"But I want to hold on a little longer, I want to try again. ”

"You call your behavior persistence? In my opinion, it's more like stubbornness. Rommel shook his head.

"Whether it's persistence or stubbornness, I haven't encountered a dead end after all, I just want to see where I can go, Rommel is in charge. Richard had no excuse.

"So, you must see a dead end before you are willing to give up?"

"Maybe. ”

Rommel fell silent suddenly, not saying a word. The white rabbit he put on the table vaguely felt the uneasy breath, his hair stood up, he glanced at Rommel in fear, and was about to jump into the arms of Canon next to him. But as soon as he moved two steps, he was swept away by Rommel, frozen in place like petrified, and picked up by Rommel the next moment.

Canon next to him stopped talking.
