Qin Ning had the experience of breaking through the bottleneck last time, and his thinking this time was very clear.

If there can be extremely powerful hand cannons, which can kill one of the opponent's firepower points with a few shots, or even one firepower point with one shot, then there is no need for a squad of fifty people to destroy the air defense system.

It is possible to achieve the goal of a battle in small groups of ten or even smaller.

But in this way, the security of these groups must be taken into account.

Equipped with ultra-small aircraft, you can solve the problem!

As long as the fight is over, you can quickly get out of the battlefield with an ultra-small aircraft, and your safety will be greatly guaranteed!

With this idea, Qin Ning came to the ordnance department again.

This time, in the ammunition of the hand cannon, a great improvement has been made. The improved Hand Cannon not only doubles the explosion power, but also adds an incendiary effect.

After several tests, Qin Ning was very satisfied with the new hand cannon equipment.

But the armament has gone up, and the corresponding tactics must also be improved.

This time, Qin Ning decided to conduct a live-fire drill.

Because the improved equipment is extremely powerful, once some members of the Rescue Slave Regiment are scared stupid by their own equipment when they are about to fight, it will be a joke.

As soon as this plan came out, Qiu Wenhe was sad. Because of a live-fire exercise, the money spent is absolutely heartbreaking.

Facts have proved that Qin Ning's decision is very wise.

During the exercise, many of the members of the Slave Rescue Regiment were stupefied by the powerful equipment. Even Wu Zhong drank on the spot, but he didn't wake up from the shock for a long time.

Qin Ning was afraid for a while, in case he felt sorry for this large amount of money. If this is really going into battle, something big will happen.

See such a situation. Ignoring Qiu Wenhe's protests, Qin Ning held another live-fire drill. If you want to train a commando team with excellent qualifications, you can't do it without taking money to smash it.

In the second live-fire exercise, the situation was good, and the members of the rescue slave group who were mentally prepared could cooperate with each other in the use of powerful ordnance. Because the noise was too loud to be heard, the Slave Liberators introduced the military sign language of the Earth for liaison and command.

At the same time, Qin Ning was also looking for a suitable target on the map of the Abyss Empire.

Wait to see the Heavenly City under the name of the second prince. Qin Ning laughed, and focused on the name of the Turning Heaven City: "Turning the Heaven Turning City? Okay, that's it, I'm going to use this slave to turn the entire Abyss Empire upside down. ”

From Lingtu City to Turning Heaven City, the straight-line distance is about eight hundred miles, which is outside the center of the Second Prince's power.

The latest information is that there are 90,000 regular troops stationed in the city, and 30,000 local armed forces. There are four large slave hubs in the city. The largest slave distribution center was a large distribution square near the center of the city, which housed more than 10,000 slaves.

Right now. The number of members of the Slave Rescue Regiment has risen to five hundred. Qin Ning took all the members of the Rescue Slave Regiment with him, rode a large flying machine, and dismounted the flying machine at a distance of a hundred miles from the Heavenly Turning City, and then ordered the Rescue Slave Regiment to take the shape of a caravan. Enter the City of Heavens.

Qin Ning specially explained that he must not be stingy with money, as long as he gives enough bribes to the troops defending the city. Then no one will seriously check it.

In this way, five hundred freed the members of the slave regiment. Divided into five caravans, they entered the Heavenly City under various business names. Money opens the way to great effect. After receiving a considerable amount of bribes, the garrison not only did not check the members of the rescued slave group who pretended to be caravans, but also showed them where to go and who to go to, so that they could avoid the inspection of the city patrols.

Qin Ning asked the members of the Rescue Slave Regiment not to act rashly, and took Wu Zhong to various large slave distribution centers to observe the situation.

Sure enough, it was a big city, and the garrison was much more formal and tighter than a small place like Ying Tiancheng.

The slave traders here should not be called traffickers, they are the real big bosses of the slave trade, and they have done a more meticulous job of guarding against slaves.

Because of the sheer number of slaves here, if they are not well cared for, there will be violence. And in this regard, the requirements of the managers of the Heavenly City are quite strict.

If there is a riot among the slaves, the slave owner will be cut down and the entire property will be confiscated.

Under such a high-pressure policy, the slave owners took care of their slaves almost to the point of perverted meticulousness.

Obviously, the battle mode like the one that took place in Yingtian City last time no longer works here.

Back at the hotel, Qin Ning and Wu Zhong conducted several oral simulation exercises, and found that they were not satisfactory.

The rainstorm pear bullets carried by the members of the Rescue Slave Regiment this time are extremely powerful, and although they can deal with the manpower of the brigade, they also have their limitations.

Because the cages in the slave colonies were cramped together, each cage was guarded by two or three mercenaries.

This is not Ying Tiancheng, the number of mercenaries can be solved. As a rough estimate, the number of mercenaries guarding the prison was a staggering 600 due to the large number of cages in the slave distribution center.

If these people were to gather together, there would not be enough for ten members of the Rescue Slave Regiment to shoot a round of rain pear flower bombs.

However, these mercenaries are scattered around the various cages and must be dealt with one by one. If you use the Rainstorm Pear Bullet, you will be able to injure more slaves than mercenaries.

Qin Ning thought of an idea and asked Wu Zhong to implement it.

Wu Zhong disguised himself as a slave trader, gave some bribes to the mercenaries guarding the cage, and then said that he wanted to pick some better slaves and ask these people to help, and then he could take the opportunity to get some wine and food, and invite these mercenaries to get together, so that it would be much easier to deal with.

According to Qin Ning's orders, Wu Zhong successfully caught up with the mercenaries in the slave distribution center. In less than two days, Wu Zhong was connected with all the mercenaries in a slave distribution center. After making some efforts to choose a decent one, Wu Zhong proposed to get together with these friends who are enough buddies.

These mercenaries were a little embarrassed. Because his duty is to take care of slaves, I am afraid that he will not be able to accept Wu Zhong's kind invitation.

Wu Zhong told these mercenaries. I also know the difficulties of the mercenary brothers, so. He will take people to buy a large amount of wine and meat, and go to the slave distribution square.

Hearing Wu Zhong say this, the mercenaries are overjoyed, it is not possible to leave their posts, but this can be had.

After receiving Wu Zhong's report, Qin Ning felt that the opportunity had come.

Immediately, Qin Ning asked Wu Zhong to notify all the members of the Rescue Slave Regiment to act tonight!

The specific plan of action was this, Wu Zhong led a hundred people to free the members of the slave group. Take the wine and meat mixed with drugs to the slave distribution center and ask the mercenaries to drink and eat meat, and after letting go of these mercenaries, immediately free the slaves, and at the same time, release some unmanned flying machines to fly in the direction of the north of the city.

In this way, the various anti-aircraft fire points of the Overturned City will open fire.

The artillery team lurking around the fire stronghold was responsible for destroying these strongholds, and after destroying the stronghold, the artillery team immediately evacuated in the north direction of the city in an ultra-small aircraft. Go straight to Lingtu City.

And the brigade of the rescue slave regiment was in the north of the city, where the air defense gap was opened, and it was also necessary to evacuate quickly.

All the members of the Slave Regiment who received the order to free them urgently acted according to the plan.

Night falls. Wu Zhong led a hundred members of the rescue slave group, carrying the wine and meat mixed with drugs, and swaggered to the slave distribution square in the picture.

The mercenaries saw Wu Zhong. They all came over to say hello to Wu Zhong. Wu Zhong asked people to put down the wine and meat, and instructed his subordinates to toast the mercenaries.

See the food. The mercenaries all poured out, enjoying the wine and fat. But. In less than a quarter of an hour, the mercenaries fell to the ground, unconscious.

Qin Ning saw the gesture from Wu Zhong in the dark, and rushed to the slave distribution square with the rest of the more than three hundred people.

Send a hundred people to clear the field to see if there are any mercenaries who have escaped the net, and the rest are thrown into the operation of smashing the cages and freeing the slaves.

Because there was an accident of a slave screaming in the process of rescuing the slave for the first time, after research, the best way to stop the slave from making a noise is not to say to the slave that we are here to save you, but to kill whoever dares to make a disturbance is the most effective.

The members of the freed slave group who cleared the field soon returned and told Qin Ning that there was no longer any obstacle. These people also threw themselves into the operation of smashing the cages.

During the whole process, no slaves screamed.

However, there are so many slaves here that there are close to fifteen thousand. There were only about 400 members of the freed slave group, and after the slaves were stunned, they had to manually move the slaves to large flying machines.

In this way, the handling time is longer.

The Heavenly City is different from the Ying Heavenly City, and the number of guards is not only large, but also very high. After a long time, I noticed that there was something strange on this side of the slave distribution square.

Immediately, a patrol of 100 people came over to check on the situation.

Qin Ning saw that he couldn't be good, and immediately ordered the members of the Rescue Slave Regiment to open fire.

It only took half a round of strafing, and more than a hundred Sky Turning City patrols were blown up to the ground and died on the spot!

But such a movement immediately woke up the city defense troops, and the alarm bell sounded like a fateful sound, and the various city defense troops stationed in the city immediately gathered urgently and immediately moved closer to the sound.

Qin Ning asked Wu Zhong to release the unmanned aircraft at the right time and float towards the north of the city. Soon, the north direction of the city opened fire on the air fire net.

More than a dozen unmanned aerial vehicles were released, all of which were shot down.

However, the exposed anti-aircraft fire network was lifted into the sky by the earth-shattering words of super-powerful ordnance and ammunition.

On Qin Ning's side, the work of transporting slaves was also nearing completion. Countless, densely packed Heaven Turning City defenders approached.

Wu Zhong took out two hundred people, lined up in an array, and with an order, the rainstorm pear blossom bullets rained down on the defenders of the approaching Heaven Turning City.

A terrifying explosion, accompanied by a sea of fire that rose into the sky, instantly killed thousands of defenders.

The rainstorm pear flower bomb, when it was tested, had a strong shock to the operators, not to mention these beaten defenders. For a time, no one dared to approach the slave distribution square.

After the fifteen thousand slaves were loaded, Qin Ning ordered everyone to evacuate quickly.

The huge aircraft took off into the air, and the ground troops could only watch the aircraft go away.

At this time, the anti-aircraft artillery fire in the north direction of the city had been destroyed, and the huge flying machine flew away from the city without encountering any obstacles.

This rescue mission was even easier than that of Ying Tiancheng.

This time, Qiu Wenhe was even more happy, after all, this was a big event to increase the source of more than 10,000 soldiers. (To be continued......)
