Liang Jian: I have a canteen

Chapter 975 Bomb Drop
After two mortar shells, the Japanese camp returned to peace again. Apart from the occasional strange cries from the Japanese, there were few other sounds.

Moreover, the Japs were already in a state of full alert and concentration, making it more difficult to attack than before.

Shen Chunliang moved to the window again, tilted his head slightly to observe the situation inside, and found that the four Japanese soldiers had almost no blind spots. Even if he could catch them off guard, it would be difficult to eliminate all four of them at once.

The drone in control seemed to notice Shen Chunliang's hesitation, so Xu San asked, "Do you need me to create an opportunity?"

Shen Chunliang pressed the switch on the headset a few times. Although no sound came out, it told Xu San, "I need it."

After confirming Shen Chunliang's answer, Xu San immediately replied, "In about twenty seconds, I will drop another defensive grenade at the door of the tent. If this plan is feasible, please answer yes!"

Shen Chunliang immediately confirmed that it would be great if he could give the enemy a chance to distract him.

The drone now carries two defensive grenades, which are usually used to create explosions on the battlefield to stop or slow down enemy attacks. They can cause physical damage and also create noise and flash effects to confuse the enemy's sight and hearing.

In addition, there are two smoke bombs and four high-explosive grenades.

These are Dong Jinbao’s stock. If it wasn’t for saving people, he would really be reluctant to take them out, because these special grenades are difficult to manufacture after leaving the Ji family.

The drone slowly flew over the tent, Xu San adjusted the angle and prepared to drop the bomb.

Although he had thrown missiles before, they were thrown directly at the Japanese positions. Even if there was a deviation, it didn't matter because it wouldn't hurt his own people anyway.

But this time it was different. If the distance was a few meters different, it was very likely that several people who needed rescue would be killed together.

The killing radius of a defensive grenade is usually between 15 and 30 meters, and the specific value may vary depending on the model and design. What is currently mounted under the fuselage is Dong Jinbao's handmade grenade, and even the manufacturer himself does not know the true explosive power. What makes Xu San speechless is that Dong Jinbao has not even done an explosion test.

There is no other way, I have to force it now.

The grenade made by Dong Jinbao weighs about 600 grams and takes about four seconds to detonate. According to the free fall calculation formula plus air resistance, Xu San needs to climb to a height of more than 100 meters before it can explode in mid-air.

However, Xu San thought it was impossible to use an agricultural drone to accurately drop bombs at a distance of more than 100 meters.

However, there seemed to be almost no wind now, and the grenade was equipped with a copycat stability tail wing made by Li Si, so Xu San thought it was worth a try.

The LCD screen on the controller shows that the drone is 122 meters high.

This distance should be about right.

After confirming the time again, Xu San decisively pressed the throwing button.

Then, the buckle under the belly of the aircraft opened, releasing the grenade's safety device.

Then Xu San saw the scene that he often saw in videos in later generations.

A grenade fell from the sky in an indescribable trajectory, and then exploded in the air about ten minutes away from the tent.

The grenade exploded and produced a strong flash and loud noise, which is the unique flash and shock effect of offensive grenades, designed to instantly disrupt the enemy's sight and hearing and give our side a chance to launch an attack.
