National Mecha: Invincibility Starts With A Million Increase!

The fighting methods of these creatures are unique and highly coordinated, as if they are attacking according to some ancient tactics. Every charge and every dodge seemed well-trained, causing Su Yang and the others a lot of trouble.

But Su Yang and his teammates were undeterred. With their tacit cooperation, they gradually figured out the attack patterns of these creatures. Tsukino used her energy shield to fend off a fierce charge from the creatures, and Jack seized the opportunity to instantly knock out several of the creatures with his beam weapon.

The battle became more and more intense, and the secret room was filled with the sounds of fierce collisions and energy fluctuations. Su Yang stared closely at the battlefield, looking for a breakthrough. He discovered that although these creatures were powerful in combat, their actions seemed to be controlled by some mysterious force.

Su Yang had an idea and decided to take advantage of this weakness. He quietly adjusted the energy frequency of the mecha and sent out an interference wave. This kind of interference wave is aimed at that mysterious power, hoping to disrupt the actions of living things.

After the interference wave is sent out, the effect is immediate. The actions of those creatures became chaotic, and their attacks were no longer so organized, giving Su Yang and the others a chance to fight back.

Su Yang seized the opportunity and led his teammates in the final decisive battle. They tried their best and finally defeated these creatures, and the door to the secret room was reopened.

They walked out of the secret room and saw a more vast underground palace. It is full of ancient ruins and technological relics, obviously the ruins of that ancient civilization.

"We need more information about this galaxy." Su Yang said, "Only in this way can we fully understand what is happening here." They decided to continue to explore the underground palace in depth, looking for more clues and secrets.

Su Yang, Yue Ye, and Jack walked slowly forward in the underground palace, their eyes scanning the surroundings in the darkness. Determination flashed in Su Yang's eyes, "We must find the source of controlling these creatures in order to completely end this battle."

"Yes," Tsukino replied, "we can't let these creatures threaten anyone again."

Suddenly they heard a low roar, followed by a tremor in the ground. A huge creature emerged from the darkness, its body covered in shining scales and its eyes like burning coals.

"Look at that! What is it?" Jack exclaimed.

Su Yang held the control stick of the mecha tightly, "That's a guardian, a creature used to protect important places in ancient civilizations. We must deal with it carefully."

The guardian let out a deafening roar and rushed towards them. Tsukino quickly activated the energy shield and resisted its first wave of attacks.

"Su Yang, we need a plan!" Jack said anxiously.

Su Yang thought for a moment, and then said: "Yueye, you are responsible for the defense. Jack, use your beam weapon to attack its eyes... I will find an opportunity to attack its abdomen."

Fighting breaks out again. Tsukino's shield blocked the Guardian's attacks again and again, while Jack's beam weapon began to damage its vision. Su Yang is looking for the right time

Suddenly, a strong light emitted from a ruin on the ground, illuminating the entire underground palace. A woman wearing ancient clothes appeared in front of them. Her name is Arya, and she is the last guardian of this ancient civilization.

Arya took a deep look at them, then turned to the huge creature: "Rest, ancient guardian, your mission is over."

The guardian lowered his head and slowly fell down, turning into a pile of smoke.

"I am the guardian of the ancient civilization on this planet, Arya. You have shown extraordinary courage and strength," she said.

Su Yang asked: "What are these creatures that are attacking us? Why are they attacking us?"

Arya sighed: "They are defense machines made by ancient civilizations, but they lost control after the collapse of civilization. I have been trying to stop them, but my power is limited

After a conversation, Arya told them that the energy core located deep in the palace must be closed to completely stop the rage of these creatures. Su Yang and his teammates agreed to help her, and together they went deep into the palace to prepare for the final challenge...
