Wang Zhong began to push forward, only to discover the enemy's defensive line was meticulously dug, with a reserve trench behind the first trench, followed by the second trench.
All the trenches were dug in a W shape, which made it difficult for the armored train to effectively use its firepower, requiring the infantry to clear it bit by bit.
Luckily, Wang Zhong's car had plenty of Naval Infantry.
When they reached the communication trench, a platoon of infantry voluntarily went down and advanced along the trench.
The Prussians hadn't placed any soldiers in the communication trench, but the Naval Infantry still advanced cautiously and searched vigilantly.
After crossing the third trench, the enemy's regimental headquarters and the sapper brigade's headquarters were just ahead.
They were completely out of sight, clearly, the Prussians had reinforced their camouflage after yesterday's Air Force bombing.
