"No, after all, there is about a squadron of Japs below, and they have not all reached the bottom of the cliff yet. When they start to climb up to thirty meters below the cliff, let me open fire. Use the three heavy machine guns you deployed behind.

Move me here and prepare to concentrate your firepower to mow down the retreating Japanese after most of the climbing Japanese are eliminated."

Chu Yunfei said.

"Understood, Tuanzuo!"

Gu Qing nodded, then waved his hand and asked a soldier to immediately lean back and deliver the order to move the three heavy machine guns on the machine gun position not far behind to the edge of the cliff.

A minute or two later, a squadron of more than 250 Japanese soldiers, under the command of the Japanese infantry squadron leader, had arrived on the ground below the cliff behind Jiangjun Ridge.

“Swiss swish!!!”

As more than a dozen ropes were thrown up, and after being hung up, the Japanese soldiers below began to pull the ropes one by one and began to climb up the cliff.

"Everyone, take out the grenade and wait for my order. After the grenade pulls the tab, wait three seconds before throwing it down!"

Chu Yunfei whispered an order to the surrounding guard platoon soldiers.

"Yes, Tuanzuo!"

All the soldiers in the guard platoon whispered in unison. Chu Yunfei's second battalion commander Gu Qing also nodded, and then also took out a grenade and prepared to throw it.

When the Japs below began to climb halfway up the cliff, Chu Yunfei gave an order, "Pull the ring, one, two, three, throw!!!"

Following Chu Yunfei's order, a member of the security platoon pulled the handle of the grenade and waited for three seconds before throwing it away at the same time.

At this time, the Japanese soldiers who were climbing up suddenly saw black grenades falling from above their heads.

"No, grenade!"

A Japanese soldier shouted in horror, and soon he was unlucky enough to be hit by a dropped grenade on his head, which exploded in an instant.

"Boom boom boom, boom boom boom!!!"

At the critical moment behind Jiangjun Ridge, as Chu Yunfei's unique skill of air-exploding grenades appeared, he had almost climbed to a height of less than thirty meters on the edge of the cliff, and grenades exploded in mid-air.

Countless Japanese soldiers who were climbing up with ropes were blown up by air-blasted grenade fragments and fell to the ground screaming. Even if they were not killed by the grenade, they were blown down and fell to death.
