Sure enough, dense shells fell down.

With a series of loud bangs, he was immediately shattered by the explosion.

Fortunately it doesn't matter.

Resurrected in full state.

You can come back.

Ready to continue squatting...

"There are rewards for survival training!" Lao Hei said lightly.

"Don't say it earlier!" Yang Yue immediately became vigorous.

I really need a reward now!

Hurry up and give me a team B. Maybe it’s okay to give me a few old A’s.

I will never fight with a bunch of rookies again...

Take out the engineer shovel and dig out the individual bunker for yourself desperately.

He is now very strong and moves very quickly, and a single bunker is completed quickly.

However, it's useless...

When the 155mm shell fell, it hung up again gorgeously.

The anti-aircraft ability of this individual bunker is very poor. Especially in the face of large-scale bombardment, the effect is infinitely close to zero.

what to do?

Is there any reinforced concrete?

No.

Then it's over.

Without reinforced concrete, how can we prevent heavy artillery bombardment?

This survival training requirement is too high...

It is simply impossible to complete!

"You should try the back-slanting fortifications." Lao Hei's voice came indifferently.

"Reverse inclined fortifications?" Yang Yue was shocked.

Oh my, it’s saved!

How could I forget?

To avoid the enemy's heavy artillery shooting, the back-sloping fortifications is the greatest magic weapon.

Look around.

The island where you are located is actually a mountain.

The relative height is about three or four hundred meters. The top of the mountain in the middle is the highest. The edges of the mountain are very obvious.

Understood.

This special training of the system is to master the reverse slope fortifications by yourself.

If he had made such a big noise in southeastern Shanxi, the Eighth Route Army had become stronger, so the Japanese would certainly not be willing to do so. They would definitely transfer those independent heavy artillery corps.

The Japanese independent heavy artillery corps are organized separately and are not under the jurisdiction of the division. Only at the military level have the right to use it.

The most powerful weapon of the Independent Heavy Artillery Regiment is the 150mm howitzer.

Well, on land, 150mm is already a very, very large caliber.

Basically, without reinforced concrete, no fortifications can withstand the bombardment of 150mm howitzer.

What?

wood?

Sorry. Too optimistic.

After one shot, all five layers of thick wood must be blown up unless there is at least five meters of soil piled on it.

However, even so, it will be destroyed after repeated bombings.

What should I do?

Only avoid it.

Build the fortifications to the other side of the mountain.

The howitzer's ballistics are straight and can only attack head-only. It can only bombard the hillside on the front. It cannot hit the back of the mountain.

Without thinking, Yang Yue took action immediately.

Hurry up the edge of the mountain and go down from behind.

"boom!"

"boom!"

The Yamato began bombing again.

Huge shells fell around the edges of the mountain peaks and exploded into huge craters.

Yang Yue lay behind the mountain, feeling the vibration from the explosion.

Good guy, the secondary gun is so awesome. If it is the main gun...

"boom!"

"boom!"

"boom!"

Suddenly, a low roar came.

It feels like the air is being shaken.

Grass!

This is the 460mm winner's gun fired!

When this shot comes, at least one of the slopes will be knocked out.

This was the largest naval gun in the world at that time!

None of them.
Chapter completed!
