After hearing the whole process, the old man's face gradually turned cold and angry. If they really follow the blue-robed man's approach, perhaps their army will be severely damaged, and perhaps the Netherworld will be able to annihilate them in one fell swoop, rushing out of the underground world and scourging the common people on the ground.

"Bastard, take him down to this seat for interrogation, if this person is a spy, then the law will be brought to justice. The old man ordered.

"Yes. The blue-robed young man answered, then took the blue-robed man from Fang Yuan's hand and pressed it down for interrogation, his eyes reflecting a strange essence.

"Looks like there's something wrong with this person. Yang Yi glanced at the blue-robed man and the blue-robed man, then looked at the old man with a smile on his face.

"Commander Yang, frightened, come in quickly. The old man apologized, and then got out of the way, letting Yang Yi and the others enter the big array.

"Zhou Wu, order everyone to set up camp, familiarize themselves with the underground world as soon as possible, increase vigilance, and prepare for battle. Yang Yi felt a little surprised by the rich attribute energy and the negligible netherworld power in the large array, but then ordered everyone to camp on the spot.

Yang Yi saw that the compatriots in the big array were injured of different degrees of severity, and the energy in their bodies was exhausted, and they could only rely on themselves to recover their injuries and physical strength, and his heart ached, and he instantly guessed that the materials here had been exhausted. So he immediately opened his mouth and ordered: "Fang Yuan, order the brothers in the group to contribute some of the pills and spars they carry, distribute them, and assist them in healing their wounds. ”

"Yes, Commander. Fang Yuan also saw the picture in front of him, and responded without hesitation, ordering everyone to contribute some of the pills, spars and other materials he carried.

Yang Yi's actions and the actions of the Free Mercenary Group moved the old man and everyone present, after all, in the underground world, pills, spars and other materials were all things to sign up for. If there are more materials, there will be more chances to survive, but the free mercenary group has given out the righteous and awe-inspiring materials, how can it not make everyone moved.

"Commander Yang, thank you very much, thank you. The old man suddenly bowed deeply towards Yang Yi to show his gratitude. Everyone present also bowed and thanked them.

"Senior, you don't have to be like this, this is what we should do. Yang Yi hurriedly helped the old man up, a little flattered.

The old man got up and smiled slightly, then looked at Sun Zhang and the others, and ordered: "Sun Zhang, the people who arranged for you to temporarily merge into Commander Yang's army, from today onwards, obey the arrangement." ”

"Yes. Sun Zhang respectfully responded, and then ordered his subordinates to merge into the Free Mercenary Regiment and temporarily include them in Zhou Wu's team.

"Come, Commander Yang, let's please, this seat guesses, at this time, what you want to know most about the situation here should be. The old man invited.

"Hahaha, it's still the seniors who understand the juniors, please. Yang Yi laughed and followed the old man into the tent.

The old man deserves to be stationed for a long time

In the underground world, the commander of the side that monitored the Netherworld, his understanding of the war and the analysis of the battle situation and his place were far beyond the ability of Yang Yi, a stunned young man. The reason why the current battle situation is urgent and very unoptimistic is not because of him, but because of the poor handling of his subordinates and the super strength of the Netherworld.

After all, only the old man in the underground world has a far-sighted strategy and mind, his subordinates have a shallow vision, and the strength of the army is weak, and it is indeed difficult to resist the Netherworld with his strength, not to mention that it is a miracle that the army in the underground world can hold on until now.

At present, the arrival of Yang Yi has given the old man hope. Although he hadn't met Yang Yi before, the moment Yang Yi assumed the position of commander of the Star Clan, the Mercenary Guild had already passed his information to him. Especially when he saw himself, saw the mental outlook of all the people of the Free Mercenary Regiment, and heard what the blue-robed man had just said, he concluded that this Yang Yi would definitely shine in the underground world and lead the human army with him to repel the Netherworld's invasion plan.

During the whole exchange, the two first introduced themselves briefly and got to know each other briefly. Among them, the old man had known Yang Yi's basic information for a long time, just to cooperate with Yang Yi to understand him.

According to Yang Yi's understanding, the old man's name is Shang Zhou, who used to be the previous city lord of the Northern Wilderness City, and after being promoted to the Zun Realm, he stepped down from the position of city lord and went to the underground world to take over the position of commander, and he has not left, which can be said to have made great contributions to the human beings of the Tianxing Continent. It was also his actions that moved Yang Yi, and he even secretly decided to help him completely repel this Netherworld's invasion plan.

The next thing to exchange was all kinds of information about the Netherworld, and Shang Zhou also explained it in great detail, which made Yang Yi suddenly open his mouth, and he had a deeper understanding of the Netherworld, and even had a way to deal with the Netherworld in his heart. At the same time, it also made him realize the power of the Netherworld, and rang the bell in his heart.

First of all, he thought of a way to extremely limit the strength of the Netherworld, and the method was to take advantage of the Nether's long-term habit of living in the underground world. Due to the gray darkness of the underground world, there is no night and day, and the light is dim, and the eyes of the Netherworld are infinitely dilated in order to be able to see farther and catch the slightest bright spot, which is completely different from the black and white pupils of normal humans.

It was the influence of this environment and the body's adaptation to the environment that allowed Yang Yi to discover a fatal flaw of the Netherworld, that is, the intense light. Because the human pupil is black and white, it can be adjusted to a strong degree, and only a short adjustment is required to adapt to it in bright light. The Netherworld's pupils are infinitely dilated, and their acceptance of strong light is extremely weak, and the degree of adjustment is also extremely weak, which can almost be seen as the extent that there is no adjustment at all.

When the light reaches a certain level, the eyes of the Netherworld will be greatly stimulated, and the pain will be excesitive, ranging from temporary blindness to lifelong blindness. Just the timing

If used correctly, the human army can take this opportunity to severely damage the eyes of the Netherworld army and damage it, so that the defect of the human race's obstructed vision in the underground world can be fully exploited and inflict heavy damage on the Netherworld army.

It is conceivable that the two opposing sides are evenly matched, one side is temporarily or permanently blind, and the other side has a complete line of sight, and the two sides are at war, and the victory must be the side with a complete line of sight. Even if the side that loses sight is strong, the weaker side with complete sight can take advantage of this advantage to equalize the defeat, or even win more with less, and finally win.

As soon as Yang Yi's method was spoken, Shang Zhou's face was overjoyed and extremely excited, because he saw the hope of victory. If this method can really be implemented and popularized, not to mention a complete victory, their human army of less than 20,000 people will still be able to delay the Netherworld army in the underground world, waiting for reinforcements to arrive.

In the end, the two of them talked about the current battle situation, and after Shang Zhou's truthful confession, Yang Yi thoroughly understood how bad the current battle situation was.

First, in terms of the number of people. Including the Free Mercenary Group and others, there are less than 20,000 people. However, there are more than 100,000 people in the Netherworld, and they are only the advance army of the Netherworld, commonly known as the most rubbish motley army, and there are hundreds of thousands, or even millions, of elite troops behind them. In terms of numbers alone, the human army that was struggling to support in the underground world was about ten times different.

Second, in terms of combat power. Humanity is hindered everywhere in the underground world, and its combat power is greatly reduced. After careful calculation, an ordinary Emperor Realm can only exert the strength of the Peak King Realm at most, and those who are not in good condition can not even exert the strength of the Seven Star King Realm. This is also the reason why the strength of the advance army of the Netherworld is uneven, its main force is the King Realm, and the human elite army with the Emperor Realm as the main force can be defeated one after another, or even almost wiped out.

Third, in terms of strategic layout. The Netherworld also has excellent commanders, who know how to deploy troops and strategic deployment. At present, the human army in the underworld has been surrounded by the advance army of the Netherworld, and it has launched surprise attacks from all directions from time to time, leaving Shang Zhou completely confused. Even the advance army of the Netherworld launched a feint, allowing the human army to drill out of the large array to pursue many times, but returned in vain, consuming a large amount of the materials they carried. If the Netherworld set a trap on the way to pursue, they would lose a lot of money if they pursued it rashly. It can be said that Shang Zhou, the commander, broke his brain.

After understanding the current battle situation, Yang Yi fell into deep thought, and repeatedly thought of a solution to the current situation in his mind. And Shang Zhou also quieted down with interest, and planted an enchantment around him, so as not to be affected by the noise outside. After a quarter of an hour of hard thinking, Yang Yi thought that if he wanted to change the status quo of the crisis, he could only start with the method he had just thought of.

"Senior, I don't know if you can take out the detailed map you have drawn now and let the juniors advise you. Yang Yi suddenly asked.

"Absolutely. "Shang Zhou will be decisive in the closest

The detailed map drawn was taken out, and Yang Yi described in detail all the knowledge, directions, and so on on on the map.

Yang Yi was extremely focused, and under Shang Zhou's narration, he gradually understood this netherworld map, which was very different from the map of the Tianxing Continent.

"Seniors, juniors have a plan in their hearts, they should be able to hold out until our reinforcements arrive, I don't know if we can talk about it?" Yang Yi asked.

"Commander Yang, but it doesn't matter, you are here to command the battle this time. Shang Zhou smiled slightly.

"Seniors, juniors think like this..."Yang Yi began to point around on the netherworld map, and carefully explained the strategy in his heart, and when there were incomprehensible questions, Yang Yi also deliberately gave detailed answers.
