Doomsday Sequence Caravan: I Have a Mechanical Heart

"I can't be sure yet." Su Mu shook his head, placed his hand on the metal shield, and while thinking, activated the mechanical heart energy in his body. A blue light appeared and enveloped the one-square-meter metal plate in front of him.

The clicking sound of mechanical transformation filled the air, and just three seconds later, a grid-like window appeared. Each grid was only the size of a fingernail, densely packed and neatly arranged, serving both to block the eerie outside from entering and to allow them to see the scene outside.

Su Mu and the others watched the bizarre scene of wanton slaughter outside, their expressions extremely solemn. The people outside were constantly wailing, their voices filled with despair and fear, but these could not stop death from coming.

Even though they were hiding inside the car, they were still dragged out one by one by those monsters and swallowed whole. The scene was extremely bloody and cruel.

Just as everyone else was stunned by the bloody scenes, Su Mu suddenly noticed something. He went to the window and looked outside. Only then did he realize that a faint blue flame was flashing across the metal shield from time to time.

Just like the arrows before.

After a moment of observation, it was discovered that only when those strange creatures touched the shield would blue flames rise up and force them away.

Seeing this, his worries immediately subsided. He turned to look at Ling Hao and the others, "This protective shield has a blue flame trigger defense."

"At least we are safe now."

"Now everyone should take a good rest and recover."

"Okay." Ling Hao also breathed a heavy sigh of relief. "Then I'll go over first and tell them."

As soon as Ling Hao left, An Xin came over, raised her hand and cast a recovery spell, which immediately restored Su Mu's spirits considerably.

Su Mu stared at her in shock. "You can actually restore my energy!"

When he transforms into metal, he not only consumes the energy within the mechanical heart, but also his physical strength.

If his energy can be restored in time, even if the mechanical heart's energy is almost depleted, he will no longer feel dizzy.

"Of course." An Xin smiled faintly, but her face also showed extreme exhaustion. "I think this should help you last longer."

"Oh." Su Mu was taken aback, feeling that there was something ambiguous about those words.

An Xin was also taken aback, realizing that her words were somewhat inappropriate. Her face flushed slightly, and she quickly added, "I was talking about your energy."

"I know what you mean." Su Mu nodded, not looking at An Xin again. It would have been better if she hadn't explained; her explanation only made things a little awkward.

An Xin's face flushed even more with embarrassment. She stammered, "Um, I'll go and get back to work."

Su Mu regained his composure and looked again at the wandering monsters outside. In just a short while, they had devoured all the people outside, leaving only blood and chaos on the ground.

The surrounding gray fog grew thicker and thicker, and he could vaguely see a strange, wandering creature more than ten meters tall sitting there like a small mountain in the depths, its pair of scarlet blood-red eyes coldly watching them.

The smaller, wandering creatures kept circling their metal shield, trying to tear it apart and break in.

However, whenever they touch any protective shield, they trigger a blue flame. Those that run fast can avoid the burning flame, while those that run slowly are directly engulfed by the blue flame.

Moreover, after observing for a while, Su Mu noticed that the flames on the protective shield seemed to be gradually weakening.

At the current rate of consumption, this protective shield can only last for a maximum of two hours.

Two hours later, the blue flames on it will completely disappear.

But in just two hours, his mechanical heart's energy won't recover much.

Thinking of this, he turned around and went to Ling Hao and the others, and told them about the situation.

"Two hours??" Cheng Jun sat cross-legged on the ground, his brows furrowed. "I should be able to recover most of my fighting strength."

"I'm about the same," Yu Yao chimed in.

"What if I add my healing spells?" An Xin asked.

"No." Before she could finish speaking, Yu Yao interrupted her directly, "You're already overdrawn. If you continue like this, you'll fall into a deep sleep."

"What is sleep compared to death?" An Xin said with a smile. "Once I get through this ordeal, I'll take a good rest."

"Then I can recover 80% of my combat strength," Cheng Jun said.

"Sigh." Yu Yao didn't speak, but let out a deep sigh.

Ling Hao, as if struck by a thought, looked at Su Mu and asked, "Can you still manufacture bullets and arrows?"

"It needs to be restored." Su Mu nodded, understanding Ling Hao's meaning.

"Well then," Ling Hao pondered for a moment, "I'll try to find a way to provide you with some metal later."

"Make as many bullets and arrows as possible."

"We'll use these at the window first to suppress any strange occurrences outside."

"This might buy us some time."

"How about this?" Cheng Jun thought of something and looked at Su Mu, "After an hour, let An Xin and the others use pistols to kill those monsters first."

"Then I'll take you out to collect some of those strange origins."

"That way you can recover quickly."

"But if we do that," Su Mu frowned. This method was indeed feasible, but Cheng Jun would have to endure tremendous harm again. "You would be in great danger."

"It's alright." Cheng Jun waved his hand. "If you have no objections, then it's settled."

In the blink of an eye, an hour had passed.

Su Mu's mechanical heart had also recovered some of its energy. Ling Hao found some steel materials such as car bumpers, and without saying a word, he raised his hand and transformed them into seven or eight magazines and five or six arrow magazines.

After installing the equipment, Su Mu led An Xin to the window and began shooting at the wandering monsters outside.

Bang bang bang! As arrows and bullets flew out, some of the slower-reacting monsters were quickly engulfed by the blue flames. Those that reacted quickly disappeared into places unseen by the monsters.

Seeing this, Su Mu glanced at An Xin and said, "You stay here and keep watch, I'll go over there."

"Okay." An Xin replied and continued to stand guard at the window, ready to pull the trigger as soon as she had the chance.

Su Mu moved to the other side, quickly opened a mesh window, and continued shooting at the eerie creature outside.

Several minutes passed quickly. Su Mu opened four windows in the protective shield, and he and An Xin took turns going to those windows to shoot down the monsters. With the protection of the shield, they easily killed dozens of small, wandering monsters.

Those strange creatures, some six or seven meters tall, or even ten meters tall, dared not approach the protective shield. They could only stand deep within the gray fog, their eyes filled with chilling light as they stared at Su Mu and his group, letting out angry roars.

Just then, the eerie creature, several meters tall, deepest within, suddenly roared, and the surrounding gray mist surged rapidly, rushing towards Su Mu and the others' windows.
