With a roar, Qin Ning instantly pulled out the psychic sword and roared with great strength.●

A sword light flashed, and the big net was cut in two pieces!

It seems that the missing scout team has been subjected to such a plot. After being squeezed by rocks, attacks on the ox-haired fine needles and attacks on the big net, it is absolutely no problem to kill a scout team through this series of attacks.

If Qin Ning had not had the psychic sword, he would not have escaped the fate of being trapped by the big network, let alone those scouts and soldiers.

With the remaining scout soldiers, Qin Ning and his group returned to the ground in a little embarrassed manner.

After on-site observation, Qin Ning basically concluded that the missing scout team had been dealt with, and it was meaningless to organize people to save these people.

The Northern Prince's strategic intention has been fully revealed, and he used these crisscrossing tunnels excavated underground to deal with the Qin army, delaying time to win the help of the heavens and then restore the rebellion.

To pacify the Northern Prince and achieve the ultimate unification of the Blue Star Empire, we must start from the maze-like tunnel, eliminate all the vitality of the Northern Prince, and kill the Northern Prince and the Black-robed Envoy.

But the maze-like design and exquisite remote control mechanism traps in the authenticity forced Qin Ning to carefully consider the attack plan.

Like the difficulties encountered in the past, Qin Ning felt that in order to win, in a new environment, he could not copy the previous victory experience and fight. When encountering new problems, he had to innovate his tactics.

The innovation of tactics often means the innovation of equipment.

The tunnels built by the Northern Prince are complex and vast, and small troops are in danger of being eliminated, while large troops are in danger of being unable to coordinate and unite.

The twists and turns effectively blocks the signal propagation of communication equipment. When the Qin army encounters complex paths, it is necessary to divide its troops to march. If the communication is not smooth, the strategic intention of coordination cannot be achieved. This is very dangerous in underground battles.

The enemy can bury alchemy products such as sensors deeply to control the movements and quantity of the Qin army. Once the Qin army is caught by the opponent in a certain part of the weak force, the brothers' troops do not know the situation and there is no time to reinforce.

In addition, the remaining armed forces of the Northern Prince are the two-legged wolf as the absolute main force. If they fight in a vast area on the ground, the Qin army can win with their superior firepower equipment.

But when you reach the tunnel, the effect of effectively attacking two-legged wolf firepower equipment such as venomous snake-oriented sniper bullets will be greatly reduced.

All the problems fell on Qin Ning, the commander, to solve all the problems faced by the Qin army in tunnel warfare.

Qin Ning handed over the command of the army to the generals in the previous year and flew back to Xijiang City. Qin Ning summoned all the alchemists in Xijiang City to explain the problems encountered by the Qin army. He asked these alchemists to offer suggestions and see if there are corresponding alchem ​​products that can improve the Qin army's ability in tunnel warfare.

Now, everyone in the entire Blue Star Empire regards the unification of the country as their own business. This disaster-prone empire has suffered too much.

From the beginning of the melee between the several princes, the people of the Blue Star Empire were in trouble. The increasing tax burden for the sake of war was enough to be affordable. It was common for displaced in the war and even become slaves.

Finally, the Qin army came. However, the North Prince and the East Prince used their madly to kill millions of people innocently.

Everyone hopes that this empire will be peaceful quickly and live a peaceful life. When they heard that the Qin army encountered difficulties on the last territory of the Northern Prince, they expressed their willingness to contribute everything they had.

An alchemist presented Qin Ning with a family-born alchemy prescription.

This alchemist is famous for discovering rare alchemy materials. Because many rare materials are buried deep underground and have to be obtained through caves, they have refined an alchemy product that can identify any alchemy materials.

This alchemy product is called golden eyes, which is similar to wearing an eye mask. When wearing golden eyes, no matter how dark the hole is, the wearer can see everything around him, because the golden eyes itself is refined based on a night vision device.

The biggest feature of the Golden Eye is that it is sensitive to alchemy materials. Whether it is scattered alchemy materials or refined alchemy products, the Golden Eye can send an identification signal to the wearer. The Golden Eye has excellent penetration power, and even the alchemy materials or alchemy products hidden ten feet deep under the ground cannot escape the Golden Eye's scandal.

Qin Ning was overjoyed when he heard this. This thing seemed to be tailor-made for the Qin army! With this thing, the sensors and mechanisms buried by the Northern Prince can be seen in full view, so that he will not be afraid of the other party’s complex defense settings.

The alchemists were extremely enthusiastic. With the lead of the Golden Eye Alchemist, everyone was afraid of falling behind. No matter what was useful or useless, they would offer everything to Qin Ning.

The enthusiasm of the public is a bit of a suspicion of helping the people. Because the improvements that Qin Ning has to make cannot require so many alchemy prescriptions.

In desperation, Qin Ning had to bring all the alchemy prescriptions into the secret room and distinguish them one by one.

Finally, after a massive amount of elimination, Qin Ning selected several alchemy prescriptions.

One is an alchemy prescription with amplification effect. This alchemy product is called an amplification meter.

If the communication equipment is mixed with this amplification instrument, the amplification instrument can receive a signal rebounding from all directions of the communication equipment and then emit it in a direction without a rebound signal.

In this way, as long as there is space in the tunnel, the signals of the communication equipment can be repeatedly turned back and forth, and can be transmitted in a direction without major obstacles, the purpose of the Qin army conducting long-distance communication and communication underground can be achieved.

The amplification meter is not only useful for communication equipment, but also has a good amplification effect on alchemy products that are located such as two-legged wolf. This also solves the problem of fully exploring the role of reconnaissance alchemy products in this complex environment.

Qin Ning also used several alchemy prescriptions to increase armor, which can reduce the load on Qin army soldiers while increasing the strength of armor.

Another alchemy product was also used by Qin Ning. This alchemy product is a burst-type alchemy product. The biggest advantage of this thing is that it can control the intensity of the explosion and control the direction.

Qin Ning knew that in the narrow tunnel, try not to carry unnecessary things, but this directional explosion alchemy product made Qin Ning finally decide to adopt it.

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

Then you can only rely on yourself. What Qin Ning has to do is to miniaturize and melee the two most effective alchemy ordnances, namely, snake-oriented and sniper bombs.

This change took Qin Ning's countless energy, because the precision of these two alchemy weapons has reached the extreme. If you want to make any minor changes, it will affect the whole body. Sometimes, because of changes in one link, changes must be made to the corresponding links connected to it.

Golden Eyes and other alchemy products were carried out in a tense and orderly manner. After hard research, Qin Ning also achieved the results of miniaturization of venomous snake-oriented sniper bombs.

After improvement, the whole of the launcher and projectile has not only been reduced, but also improved in the launch method. The venomous snake guide was originally launched into the air and then fell freely to find the target. This time it became a straight launch, and the projectile automatically searched for the target during a straight flight.

With the close cooperation of alchemists from both the military and civilians, Qin Ning quickly obtained 100,000 sets of new equipment.

Qin Ning ordered the rear to step up the refining of 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 he chose very differently from the past. In the past, he used to select strong soldiers, but this time he chose relatively slender people. In this special environment of the tunnel battlefield, thinness has the advantage.

After the equipment was issued, Qin Ning immediately organized a simulation drill. He changed the equipment all at once, and no one could adapt to it at once.

After training to adapt to equipment, Qin Ning personally led the team to lead 100,000 Qin army soldiers into the tunnel from the entrance of the three cities.

With the golden eyes, the Qin army soldiers can not only see the objects around them in the dark, but also see all the hidden alchemy products around them at a glance.

The Northern Prince is indeed insidious. He buried sensor alchemy products in all the tunnels, and sometimes buried various mechanisms.

These things are buried very deeply, and they will not be discovered by the naked eye or body perception alone. Qin Ning and Qin army soldiers removed these sensory alchemy products and control mechanisms one by one to eliminate the threats of these things to the Qin army.

Qin Ning tried to contact other generals with a communicator and found that the amplification meter was effective. Although the quality of the call was not as clear as that on the ground, it did achieve the purpose of calling in the tunnel.

Although it can communicate with each other through communication, the 100,000 Qin troops still seem very cramped in the tunnel.

Qin Ning ordered that the micro-blasting of the alchemy products be carried out in the places where the tunnels gather, and a huge space was blown up there. 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 out. As a commander, it is excellent to think about defeat before winning. Qin Ning told the soldiers not to rush to attack, but to clear out the retreat route first.
