Now everyone has left the underground world and entered the crown of the World Tree.

The world tree here is completely different from their world tree. This world tree is just a very normal world tree, and its internal space is much smaller than their world tree.

And now, they are in a room of this world tree.

"The alien invaders... have sent out another force," Old Yang exclaimed in astonishment. "They've actually sent out reinforcements. According to my intelligence, after this deployment, the military strength stationed at the alien invaders' headquarters is probably less than 10% of its usual strength."

Less than one percent?

Xu Xin and the others immediately showed expressions of surprise and confusion.

"Oh my god, what did Brother Chaoyang and the others do?" Wang Lei exclaimed. "It's only been over two hours, right? And they've already increased their numbers? Did they kill all those guys who came over?"

"But isn't this directly beneficial to us?" Zhao Xiaochuan clapped his hands, his face lit up with excitement. "Their headquarters' military strength is weak. Isn't this our opportunity? We can deal with them more easily!"

"Don't be too optimistic," Xu Xin warned. "Even if they have less than 10% of the army, it's impossible for a few of us to defeat them. Our mission is to infiltrate. Of course, at least it will be much easier for us."

"But Ji Chaoyang and the others..." Li Wenxi frowned slightly, "Why on earth would they do this... I'm a little worried that they won't be able to hold on for much longer..."

"It shouldn't be that bad. We're very well prepared," Wen Guixin said. "Even if things don't work out, we've left a way out."

The retreat is Shi Wanyun's World Tree.

"In short, our mission here is to complete our mission quickly. The faster we move, the safer they will be." Xu Xin looked at Lao Huang and asked, "When did the enemy send out their second wave of troops?"

"Just now," Old Yang said. "The order was issued half an hour ago. We've just assembled and are preparing to... well, we've already set off. I'm afraid your companions are in real trouble."

Xu Xin pursed his lips. He really wanted to contact them, but unfortunately, on the other side of the world, they didn't have the ability to send messages back.

Communication across half the planet requires satellites, but now the satellites on Earth are all equipment of alien invaders, and they cannot use them.

"How about..." Xu Ying, who had been silent all this time, suddenly spoke up, "I can go back and take a look. I can teleport back directly. I've already been here, so I can teleport back directly."

"No." Xu Xin stopped her immediately. "There's probably a war going on over there, and the World Tree over there is isolated from the outside world. You can't teleport directly into it. You can only teleport to Crystal City, which is too dangerous."

"That's right, we should not go back." Li Wenxi also said, "No matter what happens over there, we must complete our mission as quickly as possible!"

Xu Ying nodded gently: "You are right, then..."

She took a deep breath, patted her cheeks, and looked at everyone: "It's time for us to set off. From now on, let's follow the plan! From now on, the truly dangerous action will begin!"
