Ada was also shocked. "Impossible! How could an A-level monster appear in the virtual training ground? Is there a program malfunction?"

"Now is not the time to discuss this!" Ye Ling shouted, "Let's find a way to solve it first!"

"Just relying on a bunch of ragtag, weaklings like you?" The underground demon dragon spoke in human language, its tone full of disdain, "You overestimate your abilities!"

"Oh my god, this thing can talk?" a mecha warrior complained, "This program glitch is too big!"

"Shut up! Get ready for battle!" Ye Ling gave an order, and the mecha troops quickly deployed their formations, and the cultivators also used their magic weapons one after another.

"Duan Yu, let's go!" Ye Ling and Duan Yu looked at each other, and the two mechas rushed towards the underground demon dragon at the same time.

Ye Ling's mecha was like a silver lightning, nimbly dodging the attacks of the underground demon dragon, and the weapons in his hands kept bombarding its scales.

Duan Yu's mecha was like a sharp knife, accurately attacking the weaknesses of the underground demon dragon.

Other mecha warriors and cultivators also joined the battle. For a while, the training ground was filled with artillery fire and flying spells.

Under the powerful attack of the underground demon dragon, the mecha troops and cultivators suffered heavy losses.

Many mecha warriors were shot down and the cultivators were also injured.

"This won't work!" Ye Ling gritted her teeth, "We must find its weakness!"

"Its weak point is in its abdomen!" Duan Yu's voice rang out over the communication channel, "Concentrate your firepower on its abdomen!"

Ye Ling immediately passed the order down, and the mecha troops and cultivators immediately changed their tactics and concentrated their firepower on attacking the belly of the underground demon dragon.

After a fierce battle, the underground demon dragon finally let out a shrill scream and fell to the ground with a bang.

"We won!" everyone cheered.

Aida and Ling Feng walked up to Ye Ling and Duan Yu, their eyes full of admiration.

"Thanks to you this time, otherwise the consequences would be disastrous."

"We just did what we should do." Ye Ling said modestly.

"From today on, the mecha troops and the cultivators will officially cooperate!" Ada announced. "We will learn from each other, make progress together, and protect our world!"

Everyone cheered again. The gap between the mecha troops and the cultivators was completely eliminated, and they became true comrades-in-arms.

Ye Ling and Duan Yu smiled at each other. They knew that this was just the beginning.

Suddenly, Duan Yu's communicator rang, and a cold voice came: "Urgent notice, all military exercise participants return to base immediately, there is an important mission!"

Duan Yu's expression changed, and he grabbed Ye Ling's hand, "Let's go!"
