How important the spark source is to the Transformers cannot be described by a quantitative criterion at all.

It can be said that the Transformers family was born by relying on the source of fire.

They are born from the source of fire, and when they die, the fire in them also returns to the source of fire.

It was supposed to be a perfect cycle, but it was artificially broken.

There was a rare period of foreign domination in the history of the Transformers, a race known as the Five-Faced Monster actually ruled the Transformers race, and they conquered the Transformers with only one purpose, that is, to control the source of the fire.

It's a pity that the Tinder Source is not a holy object that can be touched by the five-faced monsters, and when the five-faced monsters ruled the entire Transformers clan, they even directly ordered the Transformers to draw energy from the Tinder source to build an eternal empire for themselves.

At that time, the five-faced monsters were extremely powerful, using the power of fire to create their own legions, conquering one intelligent civilization after another around them, and establishing a huge interstellar kingdom spanning several light years.

But the five-faced monster's unrestrained extraction of energy from the source of the fire finally caused a bad result.

At a special moment, the spark was extinguished.

Yes, the source of the spark that was supposed to have eternal energy was extinguished.

Having lost the source of the fire, the army of the five-faced monsters immediately fell apart. And at this moment, the Transformers suddenly woke up, and they actually awakened their self-consciousness after they had been in a daze.

Unwilling to accept the slavery of the five-faced monsters, the self-aware Transformers rise up to the challenge!

During the uprising of the entire Transformers clan, the Five-Faced Monsters fled, and the interstellar kingdom they established also collapsed.

To this day, these five-faced monsters are still alive in their lair, on a planet called Kuntasha.

As the common enemy of the Transformers, whether it is the Maniac faction or the Bo faction, they will regularly encircle and suppress the forces of the five-faced monster to prevent it from becoming bigger.

However, after the Tinder Source was lost, the Transformers at that time found a fragment of the Tinder Source, and by mistake, the Transformers actually repaired the Tinder Source, making the Transformers enter the most glorious golden age.

Unfortunately, the restored spark was lost in the civil war. It was not until the end that the source of this lost spark was found on Earth.

However, because of the struggle between the two sides, this precious source of fire was also shattered.

At that time, all the Transformers thought that they had lost the source of fire forever, and the Transformers family would disappear into the long river of history sooner or later.

But they didn't expect that here, on the moon, they actually found traces of another fire source.

"This news is so important, I need to send a message to Optimus Prime right away!" Bumblebee said almost impatiently.

Seeing that the bumblebee was so urgent, Yun Qi admonished: "Bumblebee, you don't have to be in such a hurry, anyway, we have already come here, let's go and take a look first." After all, no one can tell what is hidden in this without witnessing it with their own eyes?"

Hearing Yun Qi's words, Bumblebee thought for a moment and replied, "What Your Excellency said is not wrong, I am in a hurry. Anything can happen until it's confirmed. I need to see for myself if there's really a spark here. ”

After everyone agreed, Yun Qi began to order the Infinity to sail towards the huge cavern.

Soon as the Infinity approached the massive metal wall, a rumbling sound of machinery rang out, and the entire wall rose up, revealing a large diagonal downward passage.

One by one, the lights turned on to illuminate the almost bottomless diagonal passage.

"It seems that we are welcome to enter!" Seeing this style, Yun Qi couldn't help but say.

I have already arrived at the door, so there is no reason not to go in!

Without any pause, the Infinity plunged headlong into the massive tunnel.

As soon as they entered the tunnel, Yun Qi and the others found that this was simply a huge underground base, with various buildings of unknown function scattered all over the tunnel.

It seems to be a huge underground base for Transformers. It's just that the scale of this base is a bit staggering. To build such a base on the moon would cost more than humanity could have imagined.

As the Infinity continued to fly downward, a number of strange mechanical bodies suddenly emerged from some unknown corner. These machines possess a round body, with a large number of glowing tentacles arranged in the lower part of its circular body.

They shimmered and swirled around the Infinity.

Suddenly, a warning sounded on the screen, and it turned out that Infinity had detected that these strange machines were trying to scan and physically contact Infinity.

Finding her hull swept around by an unknown presence, Iona suddenly became nervous.

Crash!

All of a sudden, a large number of anti-aircraft beam cannons suddenly appeared on the surface of the Infinity, turning the Infinity into a hedgehog!

Seeing this scene, Yun Qi hurriedly ordered Iona to stop attacking.

"Iona, don't be so nervous, just scan it!

"But, Captain, these pesky jellyfish-like things scanned my body without my permission. Iona doesn't like it!" said Iona pouting.

Hearing Iona's words, Yun Qi couldn't help but smile bitterly. The other party is scanning the Infinity number, not your body. However, for the ship's mother, the ship's body is her real body, and in a sense, it is indeed a bit rude to scan a girl's body without permission.

Thinking of this, Yun Qi had no choice but to say to Bumblebee: "Bumblebee, do you have a way to communicate with these machines, so that they don't go around us." The most important thing is not to scan my ship again, or Iona will go berserk!"

Hearing Yun Qi's words, Bumblebee was not only a little inexplicable, but he still agreed to communicate with these machines.

Sure enough, the jellyfish quickly left the area after the bumblebee signaled the mysterious machines to stay away.

Seeing that the jellyfish were far away from Infinity, Iona couldn't help but relax her tense body and stop all beam cannon firing procedures.

When the strange jellyfish machinery disappeared without a trace, the Infinity began to accelerate forward.

Soon, following that invitation signal, the Infinity came to a massive landing platform.

When everyone reached the platform, a strange wave flashed, and the surrounding air composition suddenly changed to a state suitable for human breathing.

Sensing the sudden change in the composition of the air outside, Iona said with some surprise: "It's amazing, we have just landed, and the air around us has become a component that can be breathed by humans." There's definitely a very powerful environmental control system here!"

Hearing Iona's words, Yun Qi was also a little surprised, this place seemed to be an underground base established by an ancient Transformer. But the strange thing is that this base actually prepares a suitable living environment for human beings. Could it be that in ancient times, there were human beings living here?

Things are getting weirder.

But just as everyone was about to venture to the deepest part of this mysterious ruin, a mysterious man opened his eyes on the planet Quintasa, a distant planet from Earth.

"Hmph, the time for revenge has finally arrived!"
