1937: the Red Flag Calls Me Back to My Country to Make Stars.

Lin Chen, a genius who studied abroad, was called back to the country, which coincided with the July 7th Incident and the war was raging! As soon as we set foot on our homeland, enemy planes wreaked havoc in the sky, and our compatriots were stained with blood—— In times of crisis, the [Stars Rising] system is activated! "The chief's order: Protect Comrade Lin Chen at all costs!" "Report! The Japanese plane is coming again!" Lin Chen sneered and ordered: "Why are you panicking? Let my 'Sky Monkey' fire cannons for them!" The black powder mixed with the new formula exploded into the sky, and the enemy plane pilot screamed on the radio: "Baga! Their rockets will chase people and explode!!!" Starting from scratch, I started to develop military industry by hand, steel-making with local methods, homemade sulfuric acid, and radar enlightenment! With the support of the system, the technology tree lights up crazily! "Consultant Lin, this blueprint... Can it really make a gun more powerful than Germany's?" "Gun? Next year I want the Zero fighter to fly over my grave!" Agent assassination? Drawing theft? Lin Chen took out the [Early Warning Sensor] with his backhand: "Want to steal technology? First ask me if I will agree to the mines made in the border area!" In the past, the enemy laughed at us: "China has no technology, only flesh and blood." Now, the enemy invaders are kneeling on the ground and wailing: "Where did their weapons come from?! Is this scientific?" Lin Chen stood next to the self-produced fighter and smiled slightly: "In the past you had aircraft and cannons, but we had iron will." "Now we have aircraft and artillery..." "Excuse me, Your Excellency, is your will strong enough?" ---
