Siheyuan: Sign-In Helps Technology Soar

Qin Feng was a modern-day wage slave, drained by work and trapped in a life of mechanical repetition. After working overtime one night, he collapsed on a roadside bench. When he opened his eyes again, he had transmigrated to a lively courtyard-house world.

Just as he stood there, completely bewildered, a cold mechanical voice sounded in his mind: the Sign-In System had activated. For his first sign-in, he received 500 yuan in general currency from the 1950s and 50 industrial coupons. In those days, when supplies were scarce, that was a fortune. He used it to buy daily necessities and establish himself in the courtyard.

From then on, his daily sign-in rewards grew more and more astonishing: basic electronic component manufacturing technology, advanced materials science research reports, key aircraft engine design blueprints, cutting-edge computer chip manufacturing technology... Qin Feng realized these things could have a major impact on the country's technological development.

With a “Connections Card (Science and Technology Department)” from the System, he gained access at every turn and successfully made contact with the relevant officials. He presented them with the technical materials, and the officials greatly praised his contributions. As he dealt with them, Qin Feng showed sincerity and intelligence, winning their trust and steadily expanding his network.

Using the System's rewards, Qin Feng not only improved life in the courtyard, but also helped advance the country's science and technology. In this unfamiliar world, he turned his fortunes around with the sign-in System and wrote his own legend. More challenges and opportunities await him in the future. How will he continue to achieve greatness?
