Half a minute later, a few wisps of white smoke rose up, and a gap the size of a grain of rice appeared on the ground.

"Wodfuck!"

"Shit!"

Commons and Denver cursed at the same time.

The atmosphere was extremely tense. Veins bulged on Commons' forehead. He would never allow himself to fail in this place. "Keep hitting! Increase the force!" he shouted at Danny.

Danny gritted his teeth and stepped on the accelerator again, and the sound of the hammer hitting the target became more intense.

However, the seemingly inconspicuous ground still resisted stubbornly, seemingly indestructible.

Just when everyone was at a loss, a roar suddenly came from a distance.

Everyone looked up and saw a huge armored engineering vehicle speeding towards them.

This engineering vehicle is larger and more powerful than the previous breaker excavator. Its body is covered with thick armor, like a steel giant.

A glimmer of hope flashed in Commons' eyes, and he immediately ordered everyone to make way and let the armored engineering vehicle approach the mysterious underground building.

After the construction vehicle stopped, a technician jumped out and ran to Commons.

"Sir, this is our latest armored engineering vehicle. It is equipped with a super-powerful impact drill and high-energy explosives, and can try to attack from different angles." said the technician.

Commons nodded and said, "Let's take action immediately!"

The technicians quickly returned to the construction vehicle, adjusted the equipment, and the huge impact drill began to slowly descend.

As the drill bit rotates at high speed, a harsh friction sound is emitted the moment it comes into contact with the ground.

However, even such a powerful impact drill seemed to have a hard time dealing with the mysterious underground building.

But Commons did not give up. He stared closely at the operation of the engineering vehicle, with only one thought in his mind: he must break through this obstacle and find the enemy inside.

Otherwise, I will be so embarrassed this time!
