"Han Xue, I'm leaving soon. I've left you something!"

"This book is a weapons atlas, containing blueprints for the manufacture of various cold and hot weapons!"

"This is a medical atlas. You can use the proportions of the prescriptions in it to make pills!"

"This is a set of house construction blueprints, containing blueprints for various styles of houses and buildings, as well as the necessary materials!"

"This is a steelmaking atlas, which records several steelmaking methods."

"This book records mechanical civilization, and contains detailed explanations of transport aircraft, agricultural machines, and civil aircraft!"

As Lin Xue took out one book after another, a strange feeling suddenly welled up in Han Xue's heart.

She suddenly realized that Han Xue's departure this time might be a real departure.

That kind of thing will never happen again!

But these things were so precious that she couldn't refuse them. Besides, they were treasures for the entire country. Although she was terrified, she carefully put the books away.

"Phoenix, are you really leaving? Can't you stay? We can be sisters for life!"

Han Xue hugged Lin Xue tightly, reluctant to let her go; it was this little sister who had saved her from dire straits.

If it weren't for the phoenix, she couldn't imagine what would have happened to her.

Will they die under the sword of the Japanese devils, or become traitors despised by everyone?

Although she believed in her own heart and remained steadfastly loyal to the organization.

But Han Xue had a persistent thought: if Lin Xue hadn't rescued her, her fate would have been extremely tragic.

This kind of misery is not as simple as it seems on the level of life and death!
