Those who reincarnate must die.

The reincarnators were overjoyed to encounter fellow Shen Clan members at the altar in this unfamiliar world. After all, this was the first battlefield mission for Altar Twelve, and even with Zhang Lang in charge, everyone still felt somewhat uncertain. Now, with an additional powerful ally, they felt reassured.

"With Altar Master Diana, we're sure to win this battle!" Lu Ren chuckled. "By the way, where are the rest of you from the Thirteen Altars? Have you already been deployed to various parts of the city for vigilance?"

Speaking of this, Diana sighed: "And you're telling me! Because of my home-field advantage, this battlefield mission was originally assigned to our Thirteen Altars, but the mission was suddenly interfered with by a special item, and the participating teams were changed at the last minute."

As she spoke, Diana glanced at Zhang Lang and said, "Was this your doing?"

Zhang Lang nodded frankly and said, "There are people I want to eliminate in this mission."

"So because of you, our team's mission was canceled..." Diana shrugged. "Only I, because I'm a native, have the opportunity to stay in this world."

"I'm sorry, we didn't know..." Yue Xinyi stepped forward to apologize, "But we will do everything in our power to protect your hometown!"

"No need for apologies." Diana smiled slightly. "To be honest, when I learned that the battlefield had been chosen here, I was filled with despair. I know the capabilities of my teammates, and facing experts from higher races, I had no confidence in protecting my homeland."

"But things are different now..." Diana looked at Zhang Lang: "Your presence has given me a huge boost of confidence!"

"Don't worry. I'll do my best." Zhang Lang nodded.

"However, since we are facing an attack from three major races, we'd better be fully prepared..." Old Mo chuckled, "Sect Leader Diana, how strong is the energy shield of your Griffin City? Besides this layer of protection, what other means do you have to defend against external enemies?"

"You should have experienced this when you entered the city." With that, Diana stepped out from behind the table and into the open space in the center of the study. The floor there was covered with intricate circular patterns, which looked like some kind of magic circle.

Diana stepped on the edge of the magic circle, and a stream of magic flowed out from her toes, quickly illuminating the circle. Then, the sound of machinery running came from underground.

A moment later, the floor inlaid with magic circles cracked open, and a large number of intricate and complex mechanical parts rose from the ground. As they rose, they interlocked, operated, and deformed, and soon formed a huge metal city model standing on the ground!

"This is... Griffin City?" Ye Peng exclaimed in surprise, "It's so meticulously crafted!"

"It's a 1:5000 scale replica. You can find the corresponding major buildings and defense structures in the city on this model." Diana walked to the still-operating model and gently turned the largest cannon on the west gate wall.

"Hmm?" Zhang Lang's ears twitched, and he turned to look out the window to the west.

"Can you feel it?" Diana smiled slightly.

"What's going on?" The others were completely confused.

"The cannon in the west of the city started turning as she pulled the lever," Zhang Lang said, looking at Diana. "Isn't this just a model, or the control panel for the entire city?"

"That's right." Diana nodded with a smile. "This world was originally just a medieval world of swords and magic. Later, because I was summoned by the altar, I came into contact with all sorts of strange and wonderful worlds, and also learned many techniques and abilities that did not belong to this world."

"As the eldest daughter of the Griffin family, I used my status to promote more advanced technology in this world, hoping to make my homeland stronger... But I never expected that before I could lead a true technological revolution, four interdimensional gates would open..."

"The power of combining technology and magic is immense, but because it's not widespread enough, I only had time to defend Griffin City, and I've held out until today..."

As she spoke, Diana raised her hands, and with the pull of magic, the parts of the entire city model began to move. Along with them, the real buildings and defense facilities in the city also deformed, as if the entire city were a living steel behemoth.

"After so many years of transformation, this city has become an impregnable mechanical fortress. If it were just this one world, it would be enough to withstand any monster's attack!" Diana's tone was full of confidence.

"If it's just this world... well..." Yue Xinyi understood the implication in Diana's words.

Diana sighed, "But the situation is different now. This place has become a dimensional battlefield, and the opponents are heroes from other dimensions. I'm not confident I can hold out..."

"No need to attack," Zhang Lang suddenly said. "I'll go back and deal with the enemy when they arrive. You just need to ensure this city doesn't fall anytime soon!"

"I have no doubt about your abilities." Diana looked at Zhang Lang, her mind replaying the scene of Luo Wei's death.

"However, this dimensional war is not a one-man affair, especially in my homeland, fighting against foreign enemies. I must do my part," Diana said firmly. "Besides, this city holds a hidden, deadly weapon!"

"A Holy Giant?" Yue Xinyi thought of the side quest in the altar description.

"That's right." Diana nodded. "It was a product that combined mechanical technology with the world's most powerful magic. It's just a pity that I didn't finish it before the world was struck by tragedy."

As she spoke, Diana snapped her fingers, and a powerful figure walked in, carrying a safe, which was the very safe that Jesta and the others had fought so hard to obtain.

"Your Grace, after testing, this item has not been tainted by any evil power," the soldier explained, placing the safe on the table.

Diana nodded, took out her key, stepped forward, and opened the safe. A dazzling light shone from the safe, but it dimmed after only a moment.

Diana reached into the safe and took out a large, orange, diamond-shaped gem.

"What is this?" Yue Xinyi sensed a surge of spiritual magic emanating from the gem.

"The Eye of the Mind," Diana explained. "Legend has it that this is the magic core of the ancient orange dragon king, Kabatina, containing the most powerful spiritual magic. And I intend to use it as the... processor for the Holy Giant!"

"A magical processor?" Ye Peng, who was also skilled at manipulating giant robots, brightened up upon hearing this. "That's a novelty! With this, the giants can be activated?"

"Not yet." Diana shook her head. "According to my design, at least two more things are needed to activate the Holy Giant."
