With a roar, Qin Ning instantly pulled out the Psychic Sword, roared angrily and struggled to go up.

The knife flashed, and the big net was cut in two!

It seems that the missing scout team has been subjected to such a plot, after rock squeezing, cow hair needle attacks and large net attacks, this series of attacks is absolutely not a problem to take out a scout team.

If Qin Ning didn't have the Psychic Overlord Sword, he would not be able to escape the fate of being caught in the big net, let alone those scout warriors.

With the remaining scout warriors, Qin Ning and his party returned to the ground with a slight wolf bèi.

After on-the-spot observation, Qin Ning basically concluded that those missing scout teams had been poisoned, and now there was no point in organizing people to save these people.

The strategic intention of the Northern Prince has been fully revealed, which is to rely on these criss-crossing tunnels dug underground to make a final maneuver with the Qin army, delay time, and win the help of the Heavenly Realm and then restore.

If you want to pacify the Northern Prince and realize the great cause of finally unifying the Blue Star Empire, you have to start from the labyrinthine tunnels, eliminate all the living forces of the Northern Prince, and cut off the Northern Prince and the black-robed envoy.

However, the labyrinthine design in the tunnels and the ingenious remote-controlled traps made Qin Ning have to carefully consider the attack plan.

Like the difficulties encountered in the past, Qin Ning felt that if he wanted to achieve victory, in the new environment, he could not fight by copying the experience of previous victories. When we encounter new problems, we must carry out innovations in tactics.

Innovations in tactics often mean innovations in equipment.

The tunnels built by the Northern Prince are complex and vast, and if you enter a small army, you will be in danger of being wiped out, and if you want to enter a large army, you will face the danger of not being able to coordinate and unify.

The tortuous tunnels effectively blocked the signal transmission of communication equipment, and the Qin army was bound to divide its troops when it encountered a complicated path. If communication is not smooth, the strategic intent of coordination cannot be realized. This is very dangerous in underground battles.

The enemy can bury alchemical products such as sensors deeply, and can grasp the movements and numbers of the Qin army, once the Qin army is caught by the opponent when a certain part of the force is weak, the brother troops do not know the situation, and reinforcements are too late.

In addition, the remaining armed forces of the Northern Prince, with the two-legged wolf as the absolute main force, if they fought in a vast area on the ground, the Qin army could win with superior firepower and equipment.

But when it comes to the tunnels, the effectiveness of firepower equipment such as poisonous snake guides and sniper bullets that effectively hit two-legged wolves will be greatly reduced.

All the problems fell on Qin Ning, the commander-in-chief, to solve the problems that the Qin army would face in the tunnel warfare.

Qin Ning handed over the command of the army to the former generals, and flew back to Xijiang City by himself. Qin Ning gathered all the alchemists in the Western Frontier City together, explained the problems encountered by the Qin army, and asked these alchemists to offer suggestions and suggestions to see if there were any corresponding alchemy products that could improve the Qin army's ability in the tunnel war.

Now, everyone in the entire Blue Star Empire regards the reunification of the country as their own business. This plagued empire has endured too much.

From the beginning of the division of forces between several princes and the scuffle with each other, the people of the Blue Star Empire have been unlucky, and the increasing tax burden for the sake of war is enough to bear, and it is common to be displaced in the war, and even become slaves.

Finally, the Qin army came, but the northern prince and the eastern prince frantically resorted to methods, causing millions of innocent deaths.

All the people hoped that the empire would soon be peaceful and live a peaceful life, and when they heard that the Qin army had encountered problems in the last territory of the Northern Prince, they all expressed their willingness to contribute all their qiē.

There was an alchemist who presented Qin Ning with a family heirloom alchemy recipe.

This alchemist ancestor is famous for discovering rare alchemy materials, because many rare materials are buried deep underground, and they can only be obtained by going deep underground through guò caves, so they have refined an alchemical product that can identify any alchemy material.

This alchemical product is called the Golden Eye, which is similar to wearing an eye patch. With the Golden Eye, no matter how dark the hole is, the wearer can see the surrounding area clearly, because the Golden Eye itself is refined on the basis of night vision devices.

The biggest feature of Golden Eye is that it is sensitive to alchemy materials, whether it is scattered alchemy materials or refined alchemy products, Golden Eye can send a recognition signal to the wearer. The penetration of the Golden Eye is extremely good, even if it is an alchemy material or alchemy product hidden deep in the ground, it cannot escape the scan of the Golden Eye.

Qin Ning was overjoyed when he heard this, this thing was like it was tailor-made for the Qin army! With this thing, the sensors and mechanisms buried by the Northern Prince could all be seen in full view, so that he would not be afraid of the other party's complex defense settings.

The enthusiasm of the alchemists is extremely high, and with the golden-eyed alchemist taking the lead, everyone is afraid of falling behind, no matter whether it is useful or not, all of them will be offered to Qin Ning.

The enthusiasm of the public, on the contrary, is a bit of a suspicion of helping. Because the improvements that Qin Ning had to make didn't need so many alchemy recipes.

In desperation, Qin Ning had no choice but to bring all the alchemy recipes into the secret room and screen and eliminate them one by one.

In the end, after a large number of eliminations, Qin Ning selected a few alchemy recipes.

One is an alchemy recipe that has an amplification effect. This alchemy product is called an amplifier.

If the communication equipment is mixed with this amplifier, the amplifier can receive signals that bounce back in all directions of the communication equipment, and then transmit them in the direction where there is no rebound signal.

In this way, as long as there is space in the tunnel, the signals of the communication equipment can be turned back again and again, and they can be transmitted in the direction without heavy obstacles, and the purpose of the Qin army to carry out long-distance communication and liaison underground can be realized.

The amplification meter is not only useful for communication equipment, but also has a good amplification effect on the alchemy products such as the two-legged wolf. In this way, it is also solved to give full play to the role of reconnaissance alchemy products in the complex environment of the tunnel.

Qin Ning also adopted several alchemy recipes that increased armor, which could reduce the burden of the Qin army's soldiers on the premise of increasing the strength of the armor.

There is also an alchemy product that was also adopted by Qin Ning, this alchemy product is a blasting-type alchemy product. The biggest advantage of this thing is that it can control the intensity of the explosion, and it can control the direction of the explosion.

Qin Ning knew that in the narrow tunnel, try not to carry unnecessary things, but this alchemy product of directional blasting still made Qin Ning finally make up his mind to adopt it.

Among all the recipes, Qin Ning did not find any alchemy recipes that could improve the armament. This is easy to understand, because most of these alchemists are civilian alchemists, and they have little or no contact with the alchemy products of ordnance, and it is impossible to know this aspect at all.

Then you'll have to rely on yourself. All Qin Ning had to do was to miniaturize and melee the two most effective alchemy weapons, the Viper Guiding Bullet and the Sniper Bullet.

This change took Qin Ning countless energy, because these two alchemy weapons, the precision process has reached the extreme, and if you want to make any small changes, it is a matter that affects the whole body. Sometimes because of the change of one link, the corresponding link connected to it has to be changed.

The Golden Eye and other alchemy products were all carried out in an intense and orderly manner. And Qin Ning also achieved the results of miniaturization of poisonous snake guides and sniper bullets after painstaking research.

As a result, the launcher and projectile as a whole have been reduced not only in size, but also in the way they are fired. The Viper Guides were originally launched into the air and then free-fell in search of their targets. This time it turned out to be a straight launch, and the projectile automatically looked for the target during a straight line of flight.

With the close cooperation of the alchemists of the military and the civilian side, Qin Ning quickly obtained 100,000 sets of new equipment.

Qin Ning ordered the rear to step up the refining of the alchemy products needed by the front line, and rushed back to the front line with these new equipment.

In the army, Qin Ning carefully selected 100,000 soldiers. This time, the selection was very different from the past, in the past, it was to select the best fighters, this time it was to select the relatively slender people. In the special environment of the tunnel battlefield, being thin and small has an advantage.

After the equipment was issued, Qin Ning immediately organized a simulation drill. All of a sudden, new equipment, no one can adapt to it all at once.

After the training of adapting to the equipment, Qin Ning personally led the team and led 100,000 Qin soldiers into the tunnels from the tunnel entrances of the three cities.

With the Golden Eye, the Qin soldiers were not only able to see the surrounding objects clearly in the dark, but also the alchemy products hidden around them could be seen at a glance.

The Northern Prince is really insidious, and there are sensor-type alchemy products buried in all the tunnels, and various mechanism arrangements are buried from time to time.

These things are buried so deep that they will not be discovered by the naked eye or physical perception alone. Qin Ning took the soldiers of the Qin army to dismantle these sensor alchemy products and control mechanisms one by one to eliminate the threat of these things to the Qin army.

Qin Ning tried to contact the other generals with the communicator, and found that the effect of the amplifier was good, although the quality of the call was not as clear as on the ground, but it did achieve the purpose of calling in the tunnel.

Although they were able to communicate with each other through guò, the 100,000 Qin troops still seemed very cramped in the tunnels.

Qin Ning ordered to carry out a small amount of blasting with directional blasting alchemy products at the place where the tunnels gathered, and blasted a huge space in that place. As for the floating soil that was blown up, it was used to fill the closed caves.

Soon, a huge underground marching ground was cleared. As a commander-in-chief, it is a good quality to think about defeat before you think about victory. Qin Ning told the soldiers not to rush to attack, but to clear the retreat route first.

Except for the widening of two tunnels that could accommodate 100,000 Qin soldiers to retreat calmly, all the other tunnels were blocked. R1152
