"Dead girl, why are you suddenly in a daze in the middle of speaking?!"

Emiya raised his hand and tapped her on the head.

"Ahh It hurts! Death Guard Palace, why are you working so hard?! ”

"Who told you to talk to people without even basic politeness?"

Cui Xiaoxiao rubbed her aching head and looked at him with complaining eyes.

"Human cognition of the brain has never stopped, and questions about memory and brain structure have been studied and developed, even in the 23rd century. I'm not an expert on this, and that's all I know. ”

Human exploration of science is endless, Cui Xiaoxiao smiled slightly, only felt that the blood in her body was hot, this world is so magical, there are so many things waiting for us to excavate, isn't this the most exciting thing?

Emiya showed a disappointed expression, "So, do you know what the formula of the memory blocking drug used by Dutch scientists is?" ”

"How do I know that? I'm not an expert on this anymore! ”

"Yes, yes, you're a flashy cosmic physicist!"

"You say it again?"

Emiya had already consciously walked out of the room.

……

Emiya sat alone in the swordsmithing room, his right hand resting on his cheek, and fell into deep thought.

Coupled with what Cui Xiaoxiao said, there are a total of four ways to erase memories.

First, with the Nightmare Grip, you can control the person's mind to obey orders and yourself, so you can also order the other party to delete a certain fixed memory.

However, in this way, the accuracy of the instructions must be very high, and the memories of others must be snooped on, otherwise it is possible to forget the memories that the other party does not want to be deleted.

There is also the problem of materials, the fear of two-headed beasts is also a national treasure-level endangered species in the Barbarian Sword Country, and they are definitely reluctant to contribute an eye to me.

Second, using the Dream Sword allows the user to change their memories through dreams, but there is a paradox here, the user must clearly know that this is the dream in order to have the dominance to change. At the same time, this state of mind will be recorded in dreams, leading to doubts about the authenticity of all dreams and the inability to successfully tamper with memories.

Third, the most direct and perfect way to create a memory double-strand sword is just two sword casting artifact materials that I don't know where to go.

Fourth, electric fencing, by inducing recall, changes the electrical signal at the right time.

The risk is that the original memory structure may be destroyed, which in turn will cause brain damage.

Without enough experimental samples, rashly using this method is tantamount to disregarding human life.

Therefore, electric shock therapy is also widely criticized in the field of psychiatric treatment.

It's just that in terms of cost, this one with electric shock is the most cost-effective.

Even any sword immortal above the fourfold realm can do it. In other words, any sword can become an electric fencing.

Yes...... How so?

Emiya almost went crazy.

……

However, just when Emiya was worrying about the memory sword, there was another thing that was quietly happening that put him in a predicament-

Because of Ye Ziqing's strategy, the shrinkage of the sword casting material of the Wei Palace began to have a certain impact.

"So what the hell is Ye Ziqing doing?" On the throne of Chongjian Kingdom, there sat an old man with gray hair and extremely thin.

Even the mere thinness is not enough to describe that since the death of his most beloved son, His Majesty, the monarch who was once full of red face and had a small belly for a while, has been sharply emaciated because of longing and revenge.

Chong Sword Emperor Qi Chongyu's cheeks were sunken, and there were two black eye bags hanging from him, describing him as withered.

It's like a skeleton wrapped in thin skin.

Moreover, because his two eyes are of different sizes, the squeezed left eye makes the whole person look more neurotic.

Jia Shengsi, the commander-in-chief of the Heavenly Machine Division, raised his head and replied, "As far as my spies know, it seems that Ye Ziqing launched a movement to resist the Wei Palace, so seventy percent of the giants in the material world have stopped supplying materials related to the Wei Group. ”

"Hah!"

Qi Chongyu let out a strange laugh, like a mouthful of turbid air squeezed out of his chest.

"Hah!" Another bang.

Jia Shengsi let out a sigh in his heart, His Majesty's condition seemed to be even more serious.

Even for a while, they were courtiers who worried whether the great king would suddenly bend his feet one day.

However, he managed to miraculously use the skeleton to survive until now.

Jia Shengsi knew how powerful this king was, and even if he did go crazy, he was a wise mad king who could see everything.

Qi Chongyu's eyebrows twitched, and he made a disdainful look, "A group of clowns jumping off the beam, how much of a mess can they stir up?" ”

"Your Majesty said yes."

"The world's four major sources of sword-casting materials are all in the hands of the royal families of various countries, and the second-class Zhentian Sanfu Country also has a certain amount of reserves, those money scumbags who are indiscriminate, it would be good to be able to provide two percent of the supply, what is the use of these monarchs?"

"Your Majesty is wise."

"Hah!" Qi Chongyu let out a sigh with all his might, the corners of his mouth twitched, and he looked at him with scowling eyes, "Ye Ziqing will go to negotiate with them, right?" ”

"It should be on the way to the Heavenly Sword Kingdom." Jia Shengsi was frightened by his voice, and quickly replied respectfully.

"This stupid woman doesn't put me first!"

“……”

Qi Chongyu's fingers tapped on the armrest of the throne and said to himself, "Due to the limited manpower of laborers, and in order not to damage the terrain and environment, generally speaking, even the monthly mining of national mines is limited. He raised his head and opened his right eye slightly, "Lord Jia, do you know how much mineral development our country has every month?" ”

"Back to Your Majesty, the minister knows a thing or two," Jia Shengsi bowed slightly, as the commander-in-chief of the Tianji Division, he has buried eyeliner in almost all industries and fields, and in terms of being well-informed and comprehensive, I am afraid that there will be no second person in the whole world.

He replied like a few treasures, "The southern Shenzang Mountains, which have the largest reserves, have about 26.78 million tons of rough iron ore in a month, accounting for 60 percent of the country's total and 28 percent of the world's total output, and the development of royal-grade rough stones is about 8.67 million tons, of which ......"

"Hah!"

"Woooooooooooooo Jia Shengsi was so frightened that his whole body trembled.

Don't do this kind of thing when someone else is talking about it, okay......

His Majesty the nervous hung one leg diagonally on the armrest, clenched his fist hard, and made a gesture of retraction.

"So what do you say Ye Ziqing and their bunch of garbage can do?"

"Your Majesty said yes."

"Then you can find someone to tell Ye Ziqing, and let those garbage material dealers and garbage swordsmiths buy out one of the sword-casting materials."

"Your Majesty is wise...... Ha?! ”

Jia Shengsi's eyes widened in disbelief.
