The situation shows that things are far beyond their imagination, with the strength of the Qin army's control, even if they know all the control plans, the speed of the Qin army's echo with each other is enough to make the opponent unable to get out calmly.

But the cruel reality is that the enemy has completed the attack on the Qin army again and again under such circumstances.

The two of them couldn't find a clue at all, and Qin Ning was not around, so after discussing, the two brothers were ready to withdraw to Xichen Town and make plans again.

But on the night of the retreat into the western town, the enemy reappeared, this time not from the previous harassment, but directly attacked the heavy artillery battalion.

In a hurry, the heavy artillery battalion was destroyed, and the personnel suffered the greatest losses.

So, the two of them retreated again with the Qin army and retreated here.

Qin Ning understood the details of the situation and began to re-examine the whole thing. Mu Xiongtian and Lu Ling are both extremely experienced generals. The soldiers of the Qin army are also veterans of the battlefield, and if there is a problem once, or even twice, it is easy to understand, and it can be regarded as paralyzing carelessness.

It is even more strange that this situation can occur eight times in a row, and that the key of the heavy artillery battalion is destroyed for the last time.

There must be a deep-seated reason for this.

Thinking of this, Qin Ning didn't say anything more, but asked Mu Xiongtian to manage the troops, and let Lu Ling take him to check the scene.

Lu Ling took Qin Ning to the place where the accident occurred, although there were some signs of damage at the scene, but overall, it still remained the same.

The destroyed heavy artillery battalion still maintained its original appearance, and Qin Ning went to the ruined camp and carefully observed the clues. After observation and analysis, Qin Ning concluded. The enemy, which used high-explosive alchemy products, directly destroyed the entire heavy artillery battalion.

Although the scene of the destruction was chaotic, Qin Ning still separated twelve bullet explosion points. Other words. The enemy used twelve high-explosive alchemy products in a row to destroy the heavy artillery battalion.

Twelve high-explosive alchemy products, although the number is not much, can destroy the entire heavy artillery battalion, and their placement must be very precise. Judging by the power of this high-explosive alchemy product, as long as the setting is exquisite, ten of them are enough to destroy the entire heavy artillery battalion.

But the other party used twelve, on the one hand, it means that the enemy is more cautious, and on the other hand, it also shows that the enemy feels that time is tight and has to increase the release of such a high-explosive alchemy product to gain time.

In this way, the approximate time of the entire operation can be calculated. In addition, according to Lu Ling. Of the seventy soldiers lost by the Qin army, only eight died at the hands of the enemy, and all the rest died in violent explosions.

In this way, the enemy's time of action is more than thirty breaths. There is time for action, but how did the enemy get there?

If a tunnel is dug, how can the enemy determine the location of the heavy artillery battalion? You must know that the area around the heavy artillery battalion is heavily defended, as long as the position of the outcrop is slightly off. It will be discovered by the soldiers of the Qin army immediately, let alone destroy the heavy artillery battalion, and it will be a problem to protect yourself.

According to the estimated time, Qin Ning began to circle along the destroyed heavy artillery camp where the enemy was most likely to appear. Finally, an inconspicuous hole was found in the ground.

With a flick, Qin Ning found that this cave entrance was similar to what Mu Xiongtian and the others said. It is a small cave that can accommodate half a man's width.

Qin Ning took out the spider silk from the storage ring and tied a low-grade alchemy material to the end. Thrown along the entrance of the cave, under Qin Ning's constant agitation. Spider silk dozens of feet long soon extended into the depths of the cave.

It seems that it is really authentic. But how could such a narrow tunnel be made? Qin Ning thought of countless methods, but he couldn't figure out how the enemy could do it.

Qin Ning pulled the spider silk up, and was about to put it back in the storage ring, but suddenly noticed a slimy feeling on the spider silk. Qin Ning fixed his eyes and saw that on top of the spider silk, a layer of viscous liquid was attached.

"Lu Ling, quick, go, the Golden Horn Bull King called me!" Qin Ning looked very excited and ordered loudly.

Lu Ling knew that Qin Ning had made a discovery, so he didn't dare to slack off at the moment, and hurriedly ran out to call the Golden Horn Bull King.

After a while, the King of the Golden Horn arrived.

"Brother, is there anything you called me over?" The Golden Horn King seemed to be in a hurry, and he was a little out of breath when he spoke.

Qin Ning handed the spider silk to the Golden Horn Ox King and said, "Big brother, look at it, do you know the slime on this spider silk?"

The Golden Horn Ox King took the spider silk, examined it carefully for a long time, frowned and said, "Brother, where did you get this thing? This thing seems to be extinct." ”

Qin Ning was overjoyed, the Golden Horn Ox King obviously knew this thing. So Qin Ning told the Golden Horn Bull King in detail about the process before and after discovering this mucus.

Finally, Qin Ning asked, "Big brother, it seems that you know this thing, can you tell me the origin of this thing?"

The Golden Horn King frowned and said, "This is the mucus secreted by the Bone Devouring King Ant, it will never be wrong!" However, the Bone Devouring King Ant has disappeared in the Xiuzhen Continent for nearly a hundred years, how could it appear here? I was fortunate enough to see this thing when I was a child, under the leadership of my elders, and in the hundred years since, I have never heard of this thing appearing." ”

Qin Ning also frowned fiercely, the Golden Horn Bull King is a living encyclopedia of the demon clan, there is a thing about demon beasts, there is nothing that the Golden Horn Bull King does not know.

Since the Golden Horn King believes that this is the mucus secreted by the Bone Eater King Ant, it must not be wrong.

According to the description of the Golden Horn Bull King, the Bone Eater King Ant was originally one of the members of the Demon Clan's big family, and compared to their peers, they were huge, the size of rabbits.

The Bone Eater King Ant lives underground all year round, and digging holes in the ground is their specialty. Originally, the range of the Bone Devouring King Ant's activity was not in conflict with other demon beast groups, and it should be able to coexist in harmony with other demon beasts.

But what they eat is a big taboo, and the bone eater king ants like to eat the bones of dead high-level demon beasts the most. And these high-level demon beasts are a symbol of remembrance and worship for a demon beast race.

In this way, the Bone Devouring King Ant was despised and excluded by various demon beast groups.

Later, because of this problem, the various demon beast groups even joined forces to suppress the Bone Eater King Ant, and now they were frantically retaliated by the Bone Eater King Ant, which led to a big war.

The end result was that the Bone Eater Ant had disappeared, and the corpse of the last Bone Eater King had seen by the Golden Horn King had survived the Great War.

After listening to the explanation of the Golden Horn Bull King, Qin Ning was a little puzzled, even if the Bone Devouring King Ants could get close to the Qin army camp, their level was very low, and they would not do such a thing as blowing up the heavy artillery battalion.

Moreover, Qin Ning also looked at the corpses of the Qin soldiers who were killed, it was obviously injured by ordnance, and the Bone Devouring King Ant would never use human ordnance.

With questions, Qin Ning asked the Golden Horn Ox King to look at the hole found nearby.

The Golden Horn Bull King carefully looked at the size of the cave entrance, probed it with his hand again, turned his head and said to Qin Ning: "There is absolutely nothing wrong, what is sticky on the wall of the cave is the slime on the surface of the body of the Bone Eater King Ant, but there is one point, the Bone Eater King Ant will definitely not have such a large body, this should be the trace of a human body." ”

Qin Ning thought for a moment and said, "Big brother, is there such a possibility, that is, to peel off the skin of the Bone Eater King Ant, make something similar to armor, and then let people wear it, so that people can have some of the functions of the Bone Eater King Ant?"

The Golden Horn King thought for a moment and shook his head and said, "Impossible, I've seen the Bone Eater King Ant, its skin is very soft, and it can't be processed at all." Otherwise, it wouldn't have secreted that mucus when it was underground. ”

Qin Ning pondered for a long time and said, "Big brother, what method did the demon clan use when they dealt with the Bone Devouring King Ants back then?"

"This is a bit troublesome, and the demon clan also suffered a lot when they dealt with the Bone Devouring King Ants. Because this thing burrows so fast, there is no trace of it. Later, the power of the demon clan discovered that if the Bone Eater King Ant wanted to secrete the mucus on its body, it had to eat the bones of high-level demon beasts. According to this clue, it was determined that the Bone Eater King Ant had to return to the nest every once in a while to replenish its own food, and it was only by following this clue that the Demon Clan broke the Bone Eater King Ant. ”

This clue is very important to Qin Ning, and there is no other way of thinking at the moment, so he can only try it according to the method provided by the Golden Horn Bull King.

If there is such a group of people who have the physical skills of the Bone Eater King Ant, then they will also need to replenish the high-level demon beast bones of the excavation passage just like the Bone Eater King Ant.

There is only one enemy now, and that is the people in the City of Celestial Glory. The source of replenishment will also be in the direction of Tianyao City, and digging a passage is not an easy task, that is, there should be a replenishment transfer station in the middle. This transit station may be the place where this special group of people gathers.

Extrapolating from the time when the Qin army suffered several night attacks, the range of the most likely activities of the incoming enemy was roughly delineated. In these places that may be transit stations, Qin Ning marked them one by one.

After making the marking, Qin Ning ordered people to quietly approach these places, and instructed the Qin soldiers on the mission not to startle the snakes, just quietly probe around the marked points, and don't make their own decisions when they find the situation, and report it immediately.

The soldiers sent out conducted a large-scale search according to Qin Ning's orders, and soon, a clue was reflected to Qin Ning, and signs of unknown people's activities were found fifty miles southwest of Xichen Town.

Qin Ning asked the soldiers who discovered the situation to be careful, don't alarm the other party, and he hurriedly flew to the place where he reported.

When he arrived at the place, Qin Ning found the soldier who reported the situation, and under the guidance of the Qin soldiers, Qin Ning quietly approached the place where the abnormal situation occurred. (To be continued......) R1292
