After absorbing the captives of the South Sudanese and Sudanese armies, the number of the Sandi tribe army has exceeded 100,000, reaching 110,000. Pen % fun % Pavilion www.biquge.info

However, the newly collected prisoners have not yet undergone systematic training, and even due to the rush of time, even the establishment has not been completely straightened out, and the combat effectiveness is even more ant wearing tofu, and it cannot be raised.

What really has strong combat effectiveness is the 30,000 army of the original Sandy tribe.

Wang Ning sent the newly collected team to the border to garrison, and led the original 30,000 troops of the Sandy tribe to the mountain pass in the direction of Erunmubia.

South Sudan and Sudan have been defeated by the Sandy tribe and suffered heavy losses, and they can't organize an effective attack for a while, so they send newly recruited troops to guard the border, and Wang Ning doesn't have to worry about what problems will happen.

After receiving the news of the defeat of the South Sudanese army, the commander of the Erunmubia army, Saluli, originally wanted to arrange the army under his command in echelons like the commander of the Sudanese army, Puding.

However, there was an order from the rear military headquarters to let Saluli stick to the position, and the military headquarters would immediately send reinforcements to Saluli, equipped with a large number of anti-aircraft weapons, and there was no need to be afraid of drone bombing by the Sandy tribe.

Reinforcements sent by the military arrived soon.

The reinforcements included three anti-aircraft artillery divisions, an anti-aircraft missile brigade armed with several thousand anti-aircraft guns, a large number of portable anti-aircraft missiles, and even expensive terminal missile interception systems.

These equipment are all provided to the military by the pillar of the Demon Gate, and it is quite equivalent to use anti-aircraft guns to fight UAVs, but to use portable anti-aircraft missiles to fight UAVs is a bit of a fuss and a waste.

And the use of terminal missile interception systems to deal with UAVs is unprecedented in the history of world warfare.

In order to deal with Wang Ning, the pillar of the demon gate spared no expense.

The army of the Sandy tribe defeated the South Sudanese army, and immediately turned around and pounced on the Sudanese army, and it was too late for the Pillar of the Demon Gate to support the Sudanese army.

Therefore, the pillar of the demon gate put all the bets on the army of Erlunmubia, hoping that the army of Erunmubia can complete its efforts in one battle, defeat Wang Ning's Sandy tribe army, sweep Wang Ning's base area, and then get rid of Wang Ning.

In order to get rid of Wang Ning, the Pillar of the Demon Gate is already unscrupulous, regardless of the cost, as long as the army of Erlunmu Biya can win, they will not hesitate to pay no matter what the price.

At the same time, the Pillar of the Demon Gate arranged for the Erunmubiya military headquarters to build an airstrip in the rear several hundred kilometers away from the camp of the Erlunmubia army, preparing to send a large number of advanced fighters to participate in the battle and come to support Saluli.

The two unmanned high-altitude reconnaissance planes controlled by Estein had just flown over the camp of the Elumbia army, and before they could see the situation clearly, one of them was shot down by a portable anti-aircraft missile launched from below.

The remaining high-altitude unmanned reconnaissance aircraft did not last a few seconds before it was shot down.

Fortunately, the second high-altitude unmanned reconnaissance plane, before it was shot down, transmitted back images of the ground situation, and these images were recorded by the computer in time.

After carefully studying the replayed images, Wang Ning was surprised to find that the air defense system in the camp of the Erunmubiya army was very tightly arranged, and it could even be said that it was a little too tight, which could almost be described as a metamorphosis.

Around the outermost layer of the camp, every ten meters, an anti-aircraft gun was arranged, and thousands of anti-aircraft guns surrounded the entire camp.

One level further in, there are man-portable anti-aircraft missiles, the number of which also reaches thousands.

At the core, a phased array radar has been erected, and a very advanced missile defense system has been arranged, and judging from the degree of sophistication of these missile defense systems, it is likely to be the latest high-end product developed by the United States.

It is no wonder that the high-altitude unmanned reconnaissance plane was shot down as soon as it flew over the camp of the Elunmubiya army.

Nima, with such a tight air defense system, not to mention a high-altitude reconnaissance drone, even if a fly wants to fly in, it is as difficult as climbing to the sky.

A three-meter-high fence was built around the camp of the Erunmubiya army, and at the top of the wall, a two-meter-high power grid was erected, which made it difficult for Wang Ning to sneak into the camp.

Originally, the unmanned bomber was the best weapon to crack this arrangement, but now the Erunmubia has strengthened the air defense system, and the unmanned bomber is difficult to get close to the camp and cannot play a role, which is equivalent to the unmanned bomber, which is a sharp weapon, and has been abolished.

What's next, and what steps should be taken to break down your adversary's defenses?

Wang Ning frowned and thought for a long time, but he was still puzzled, and there was no way at all.

At present, the enemy forces in the direction of South Sudan and Sudan have been completely defeated, and the Sandi tribal plain has been relieved.

But the 100,000-strong army, which is eyeing it here, is still a great threat to the Sandy Tribal Plains after all.

What's more, behind the 100,000 army of Erunmubia, the pillar of the demon gate is manipulating.

The relationship between the Pillar of the Demon Gate and Wang Ning is an endless relationship, and he will definitely not sit idly by, watching Wang Ning's Sandy tribe grow bigger, he will definitely find ways to use all means to eliminate the Sandy tribe.

Because of this, Wang Ning must pull out the nail of the Erunmubia army.

But how to pull out this nasty nail, Wang Ning felt a little clueless.

Seeing Wang Ning frowning and thinking bitterly, Ji Siting looked sad, and he also wanted to share his worries for Wang Ning, and suddenly remembered the story of the tunnel war told by the Chinese instructor.

If we can't get into the sky, we can drill into the ground.

So Gistin suggested to Wang Ning that he could enter the camp of the Erunmubia army from below by digging a tunnel.

Wang Ning's eyes lit up, and he felt that this method was good, so he ordered Ji Siting to organize people to dig tunnels and try tunnel operations to see if they could break through the defense of the Elun Mubia army from underground.

Gistine received the order to go down and organize the troops to carry out the tunnel operation.

The tunnel operation is simple to say, but in fact, the technical difficulty is still very large.

The first thing is to keep it secret, if the enemy knows that you are digging a tunnel, it is easy to prevent it, in the era of backward ancient technology, it is still so, modern science and technology are so developed, and the means of defense are more abundant.

Basically, once detected by the enemy, the tunnel operation is equivalent to failure.

Gistine was also very aware of this, and he organized his soldiers to dig inside the fortress of the mountain pass, and the remnants of the excavated soil were transported to the valley for storage, and must not be seen by the enemy.

The camp of the Erunmubia army was built dozens of kilometers away from the mountain pass fortress, and the tunnels had to be dug dozens of kilometers of tunnels to dig into the camp of the Erunmubia army.

Such a long-distance tunnel is definitely not a small project, and the time of construction, how long it will take, Gistine has no bottom in his heart.

When he encountered difficulties and found the boss, Gisting found Wang Ning and told him about his difficulties.

Wang Ning couldn't figure it out, so he decided to consult with science maniacs.
