Technoblade’s execution took place on December 16, 2020. With Tommy in exile, L’Manberg’s main goals were to kill Techno and Dream. It was secretly organised by The Butcher Army, Tubbo, Fundy, Quackity and Ranboo, to punish Techno for the war crimes he committed during the Manberg-Pogtopia War, even though Techno retired from violence after the War.

The Butcher Army first put Philza under house arrest, suspicious of having ties to Techno. While looking for anything that could guide them to Techno, they found a compass that led directly to Techno’s home in the Arctic. Guided by the compass, they arrived at Techno’s cabin, met by Techno in front of his house. Techno told them that he'd changed and mentioned how much he'd been trying to fight against the voices in his head begging for blood during his retirement. Techno still tried making a break from it but The Butcher Army caught up to him, and Techno announced that, since there was no other way, he’d chosen blood. Techno managed to kill Tubbo and Fundy before he began going straight for Ranboo until Quackity grabbed Techno's prized horse, Carl. Quackity threatened Carl's life if Techno didn't surrender, taking the horse's diamond armor away. Techno complied, handing over his armor, weapons, and potions as requested by Tubbo and the Butcher Army.

The group of four escorted Technoblade back to L'Manberg, where he was expected to "stand trial" for the war crimes he committed. However, it was revealed when they arrived, that the L'Manbergians had no intention to hold a trial, instead directly deciding to execute Technoblade. Techno was forced into a cage and Quackity explained the mechanisms of the execution. An anvil would drop from above, killing him instantly.

Tubbo began to make a speech, only to be interrupted by a trident-wielding Punz. Punz attacked the L'Manbergians, attempting to place down TNT on the podium. In the chaos, Quackity managed to push the lever to drop the anvil. However, when the anvil made contact with its prey, Techno survived, gaining the achievement "Postmortal" by using a Totem of Undying before making his escape.

While the L'Manbergians were distracted, Dream rescued Carl from the pit and returned the horse to Techno. He showed Techno a secret tunnel that led into the Final Control Room. Inside, Dream had prepared some supplies for Techno to use including a pickaxe and a full set of iron armor. Techno was in the middle of thanking Dream when he was abruptly interrupted by a pursuing Quackity.

After Techno, once again monologuing his disapproving of government, Quackity challenged him to fight after noticing his set of iron armour compared to his maxed out netherite armour. Techno agreed and was able to grab strength potions from his ender chest, splashing himself and his netherite pickaxe, killing Quackity instantly with said netherite pickaxe. He stole Quackity’s belongings and rode Carl through The Sewer System, escaping by boat when he got to Ant’s Animal Sanctuary.
