The grenade hit the mirror man in the chest, and his body exploded into pieces of minced flesh with a "thud" in the air.

After killing the other party, Ye Chuchu immediately retracted his body back into the turret, and his movements were done in one go, which amazed the other three girls.

"Will there be one of these Tiger tanks?" Wang Linlin asked.

"If you can't get one, be careful." Ye Chuchu said in a deep voice and reloaded his pistol with a grenade.

At this time, three "Porsche Tigers" had already been destroyed, two of them could not move, and the remaining three "Porsche Tigers" immediately retreated while firing their guns. The four Soviet heavy tanks pursued closely, but Sun Hui asked Du Lili to slow down, so that he could turn the turret and approach the two "Porsche Tigers" lying on their stomachs and kill them one by one.

These two "Porsche Tigers" only suffered mechanical failure due to the violent vibration caused by the bullet, and they did not lose their combat effectiveness, and they had just shot at the "Mother of the Motherland" and hit, Sun Hui did not want to let himself be hit by them in the butt of the "KV-220" tank when he was pursuing.

After killing the two "Porsche Tigers", Sun Hui saw that the three "Porsche Tigers" had run a little far, so he asked Du Lili to speed up and catch up.

But at this moment, a dull loud bang came, and Sun Hui saw that something seemed to fly out of the woods and hit the "Leningrad" that rushed to the front.

"Leningrad" came out with a large spark, stopped at once, it turned its turret, as if looking for the enemy, and at that moment another shell flew from another direction and hit the side of its hull, this time "Leningrad" emitted black smoke, and then the flames rose.

Seeing this scene, Sun Hui and the girls were all taken aback.

No one was more shocked than Sun Hui, because it was 42 years now, and as far as he knew, the things that the Germans could beat his DIY "KV-220" heavy tank almost didn't exist!

Could it be that because he has changed the relationship of history, some big killers that should have appeared later have now been born ahead of schedule?

Seeing the destruction of the "Leningrad", the "T-150" tanks of the "Neva" of the Solnyrev crew immediately began to take revenge, and the "Neva" fired a shot in the direction of the enemy's artillery attack, which, although it did not hit the opponent, set fire to the surrounding trees, forcing the opponent to emerge from hiding place and rush out.

Sun Hui saw clearly what it was this time, and he couldn't help but feel a pang in his heart.

"Brother Sun, what is that?" Ye Chuchu's voice sounded behind her, and her voice was a little choked, obviously grieving because of the sacrifice of the Andreasdorf crew.

"It was supposed to be an early 'Ferdinand' heavy tank destroyer, with thick armor and a powerful 88mm 71x gun, which should not have been there at this time." Sun Hui replied simply, but his hands were operating quickly, aiming at the "Ferdinand" heavy tank destroyer with his cannon.

He was now able to determine that it was Dr. Porsche who had brought out this monster in advance by killing them and asking for credit from Hitler in order to turn over the battle.

Sun Hui didn't know that Ferdinand. Dr. Porsche, a genius designer, has been very unwilling and unhappy after losing the bid with Henschel. In order to turn the tide, Dr. Porsche racked his brains to convert the new chassis into a new self-propelled gun, but this proposal was rejected by the German top brass at the first time, because the cost performance of such a modified field gun was too low. Dr. Genius didn't want his design to be stillborn. He stubbornly pondered various possibilities, and finally once he met Hitler directly and presented him with his elaborate plan, that is, to add a new generation of 88 mm 71 caliber long-barreled guns to the original chassis, with a fully enclosed turret, anti-tank performance and survivability to surpass the existing self-propelled anti-tank guns. He confidently said that the new type of combat vehicles can be attacked, retreated, and defended, and can effectively suppress the numerical superiority of Soviet tanks when relying on preset fortifications, and the heavy armor can make it stand in the most dangerous battlefield, which is exactly where the self-propelled anti-tank guns that the German army relies on cannot gain a foothold.

Hitler, the only audience present, shouted with joy upon hearing this suggestion: "Excellent! Our soldiers need such weapons!" This sentence is not just to comfort Porsche, in fact, it is true, at this time he has received the news that 4 "Henschel Tigers" not only failed to kill the "Witch Car Group", but his own army was wiped out, and he was annoyed, Porsche's proposal made him have the idea of using a new heavy tank destroyer to kill the "Witch Car Group", and he was proud that he could not tolerate such a small Soviet tank team challenging his majesty.

In this way, the conversion of the chassis of 90 "Porsche Tigers" into new tank destroyers is not only feasible, but also imperative. On Hitler's instructions, Speer, the wartime Minister of Armaments Production and Industry, formally asked Porsche to produce 10 tank destroyers in the shortest possible time to deal with the "witch car group". Porsche miraculously brought its design back to life. Immediately after receiving the order, Porsche approached Alkate, who knew that his strong point was the design of the chassis and the action part, and Alkate had already made a name for itself in the field of modified self-propelled guns. To Porsche's delight, Alcket's company soon agreed to work with Porsche AG to design and manufacture the fighting compartment.

Porsche's team worked hard to complete the bodies of the first 10 heavy tank destroyers in a very short time, and Alcite successfully completed the assembly of the fighting compartment in a short time with the factory's production line almost full. After this effort, 10 destroyers were successfully assembled at the Nibelungen plant and sent to the front. Hitler named these new vehicles "Ferdinand", that is, the name of Dr. Porsche, as a consolation and preservation of the reputation of his old friend's previous unsuccessful bid.

The main armament of the "Ferdinand" heavy tank destroyer is a Pak43 88-mm 71-caliber anti-tank gun manufactured by Krupp, with a total weight of 2,200 kg, and the ammunition used is armor-piercing shells and grenades, with an ammunition base of 55 rounds. Among them, 20 armor-piercing shells and 35 grenades. When firing armor-piercing shells, the maximum firing range can reach 5000 meters, and at a distance of 500 to 2000 meters, it can easily penetrate 159 to 207 mm thick steel armor with an inclination of 30 degrees.
