The army that was going to enter the city was already in the crisis of war at the moment, although the news of the battle on the front line had been blocked by his order, but such a construction of defense had made many people guess the result, and now their morale is low.

There is only one passage in the mine, and there is no other way to do it except to drive the war eagle through the mountains, and the tribe has no second way to capture the mine, even if Shi Xuan and their war eagles successfully parachute into the mine, they will be surrounded by hundreds of thousands of troops because of the lone army, and it will be difficult to escape when the time comes.

Shi Xuan and the others carried out a complete reconnaissance around the camp around the mine on the top of the mountain, and the Imperial patrol found their war eagles, and on the tower, many heavy ballistas fired at them fiercely, and they had to fly out of the reconnaissance range, but the overall reconnaissance results were still obtained.

The mountains of Beicang are vast and boundless, and it is difficult to cross the mountains, and in the deep mountains in the distance, there seems to be a more powerful fierce bird skimming the sky, which is full of dangers.

"Senior brother, let's go, the Shadow Tiger Legion can be said to be at the top of their game now, and they still have a lot of spirit masters, which poses a huge threat to our reconnaissance," Lin Zixu said.

"The overall military deployment has been almost scouted, let's go, and leave the rest to Hulan Ruoyu to deal with", Jiang Yuheng led everyone to cross the mountains and leap over the jungle and return to the camp again, and some of their disciples handed over the complete reconnaissance map to the commander of the tribe, Hulan Ruoyu.

"High Priest, this is the result of our investigation, you can see for yourself," Jiang Yuheng said.

"I will have a good discussion with my subordinates, and you will need a lot of cooperation in this battle," Hulan Ruoyu said.

"I have something I want to ask the High Priest, next, if our allied military operations go well, we will help you recover the land of Beicang, how do you deal with this mine that is related to the situation in the world?" Jiang Yuheng asked the questions they were concerned about in front of all the people.

As soon as these words came out, everyone tensed their nerves, and the existence of the mine was related to the safety of the entire continent, which was a matter of concern to both sides.

"You have also seen the location of this mine, it is on the land of our northern cang, naturally it will not fall into the hands of the south, as for how to distribute it among our tribesmen, it is not up to you to interfere?" said a shaman, and many people immediately responded.

"Of course, your spirit master forces are crucial to this operation, and we will also give you a sum of ore to your satisfaction, but the mine must be in our hands," said another man.

"Grand Priest Hulan, is this what you mean?" Li Dufeng stood up at this time.

"Although my subordinates have mixed opinions, one thing is certain, and that is that the mine must be in the hands of our six royal families," Hulan Ruoyu said firmly.

"Without the assistance of our Tianhua Sect, Divine Sword Valley, and Ranger, are you confident that you can take the Imperial Shadow Tiger Legion garrisoned by a hundred thousand troops?" Li Dufeng said.

"Do you want to tear up the covenant now?" said Hulan Ruoyu.

"We have an old saying called ugly saying in front of us, and I can tell you with certainty that you six royal families don't want to monopolize this mine, and we must occupy half of the mining rights, otherwise, the situation that the empire is facing today will also be faced by your tribes", Li Dufeng said strongly.

"Your appetite is too great, although your spirit master is powerful, but our shaman is not afraid, without you we will take down his Shadow Tiger Legion", someone said.

"Oh, then you can give it a try, and when the time comes to throw away your armor, don't blame us for not helping," Li Dufeng said.

"Okay, the war is not over yet, it's too early to say this, maybe we can wait until after repelling Yao Jingcheng?"

"No, this matter is very important, and our head of this matter personally ordered us to negotiate, otherwise this alliance will be dissolved, and we will find another way to deal with the empire," Li Dufeng said.

"I can't decide this matter alone, we six royal families need to discuss it before we can give you an answer, give us three days?" Hulan Ruoyu said.

"You'd better hurry up and decide, but I heard that reinforcements from within the empire have begun to be dispatched, and there will be no chance to be attacked by the enemy at that time", Li Dufeng led the disciples of Tianhua Sect to leave the military tent.

"It's too much of a bully, and without them, I don't believe that a mere 100,000 troops can stop our attack?" Kunhe said angrily.

"There is no need to quibble in this matter, let's send a message to our king, and it is up to them to decide," said Hulan Ruoyu.

They were chosen to return to their camp, and everyone began to be on guard, at this time the tribe was no longer trustworthy, and they had to remain vigilant.

"Shi Xuan, what do you think they will do with this matter?" Zhao Zhuo asked.

"I don't think they should give up half of the mining rights, who is willing to give up the fat in their mouths?" Shi Xuan said.

"So our covenant has expired?" Zhao Zhuo said.

"Don't worry, sooner or later they will come to the door to beg us, with their undisciplined attack, they can't help the imperial army, and when the imperial reinforcements arrive, they will be attacked by the enemy and collapse sooner or later," Shi Xuan said.

Sure enough, three days later, Hulan Ruoyu received a reply from the kings of the six royal families, and they could break the covenant and never give up the right to occupy the mine, such a result had long been expected by Li Dufeng.

With the pact shattered, Li Dufeng led all the spirit masters back to their own station, away from the tribe's camp, and the two sides lost the basis for cooperation and no longer trusted each other.

"Senior brother, is their tribe so confident?" Dai Mengli asked Jiang Yuheng.

"Since the alliance, the victory in many major battles has given them great confidence, and the many arcane ** they have captured before have made them even more proud, let them feel the power of the Shadow Tiger Legion, and we can rest and recuperate," Jiang Yuheng said.

"It's really a wave of unsettled waves, when will the chaos in Beicang be calmed down?" Dai Mengli also complained.

"Why are you homesick?" Jiang Yuheng asked.

"Hmm", Dai Mengli nodded.

"Wait a minute, there are many good things, the empire has developed over the years, and its strength far exceeds that of other countries, if you want to deal with them, you can't do it without a little patience," Jiang Yuheng said.

The situation in Beicang was confusing at one point, and they lost the support of the Spirit Master's troops, and the troops decided to carry out a military operation on their own, and they even sent a large number of war eagles to search Shi Xuan's camp, they didn't want to be destroyed by the Spirit Master at a critical moment.

After Li Junxian died on the battlefield, the empire was not reconciled to the defeat of Beicang, Yao Jingcheng's 100,000 army still held its position, although the tribe won a big victory, but the number of troops was still lost more than half, Jiang Bingkun once again launched a large army to support, as long as Yao Jingcheng held the position for enough time, the tribe's army was attacked by the enemy and would face the danger of annihilation.

In the imperial city, Jiang Bingkun is a lot older at this moment, the war in Beicang once collapsed, almost shattering his dream, this time he almost exhausted the core strength of his central garrison army, so far he can no longer mobilize any garrison to reinforce other fronts, once the other fronts are defeated, his empire will face a crisis.

"Wuji, do you think Yao Jingcheng can stop the siege of Beicang's army this time?" Jiang Bingkun looked at the minister who was following him with some amazement.

"Yes, surely, General Yao has been favored by His Majesty since he was a child, and his strength is strong, and he will definitely swear allegiance to the empire," Wei Wou-Ki said.

"You've said that every time before, but every time your words haven't come true," Jiang Bingkun said.

Wei Wou-Ki bowed his head in shame, not daring to talk.

"In the middle of the court, although Li Jiye, the head of the household department, has always been against me, but as a veteran of the three dynasties, he has played his role, and you have dealt a blow to his power over the years, but you have disappointed me at the critical moment," Jiang Bingkun said.

"Your Majesty is angry, it's the incompetence of the ministers", Wei Wuji was terrified.

"However, for me, dominating the world is my lifelong obsession, I can't tolerate anyone who is against me in my eyes, he chooses to disobey me, that is, the person who hinders my progress, I will not keep him by my side, but I also hope that you will not live up to my expectations, otherwise I will not let you go", Jiang Bingkun said angrily.

The ministers followed him tremblingly, and they didn't dare to speak anymore, since Li Jiye's forces were cleared by them, there was no one in the court who dared to speak, and Jiang Bingkun became a real loner at this moment.

The Beicang Mine was thousands of miles away, and it would take a long time for his reinforcements to support him, even if he marched at full strength, which gave the Beicang tribe the opportunity to attack.

Hulan Ruoyu finally lost his patience, he didn't want to wait until the imperial reinforcements arrived to be attacked on his back, and he began to fully deploy an attack.

However, the narrow mountain roads were easy to defend and difficult to attack, and the empire easily held several attacks with the help of excellent war fortifications, and their offensive teams had a very long battle line, which was very easy to be broken by the empire one by one, and they lacked effective training, so their attacks were disorderly, and they lost a lot of their subordinates in a few days.

In the military tent, Hulan Ruoyu was obviously very dissatisfied with the war situation, and he loudly reprimanded these subordinates for not doing things well.

"High Priest, their defenses are impregnable, our warriors are suitable for the steppe charge, this unique terrain is very unfavorable to our warriors, they rely on powerful weapons of war to suppress us, we are very passive", the general responded.

"What about our war eagles, we have captured so many arcane **s, haven't we used them?" Hulan Ruoyu said.

"They have too many towers, many of their warhawks have been shot down by them, and they have obviously trained us in war deployment," the general said.

"This is not an excuse, the mines must be in our hands, even if at all costs, clear the way into the mines, order our shamans to attack at night, their ballistas are difficult to aim, and our odds are very good", Hulan Ruoyu continued to launch an attack on the Empire.

Taking advantage of the night, the shaman of the tribe drove many war eagles out and launched many surprise attacks on the imperial army, but under the dark night, it was also difficult for the shaman in the high altitude to find the target of the enemy's tower, and the other party extinguished the lights of the tower in response to their night raid, and the effect of their raid was not obvious.

Although Jiang Yuheng and the covenant between them and the tribe were broken, they did not give up the reconnaissance of the empire, the outcome of this war is related to the future, and they dispatched personnel every day to closely monitor the movements of the warring parties.

"Senior brother, their attack obviously didn't have much effect, such a narrow road, easy to defend and difficult to attack, every time they capture a pass, it will cost a lot of tribal soldiers, if this continues, when they reach the base camp, the people of the tribe will almost die," Zhao Tianhu said.

"Actually, in the face of such a strong defense, it is not difficult to deal with them, now Yao Jingcheng is most worried not about a head-to-head confrontation, but about grain and grass, they have been besieged for many days, and the supply of food and grass has reached an extremely tight point, if their shaman chooses to take a detour and directly attack the granary of the base camp, this is much better than attacking the tower," Lin Zixu said.

"It's better to let these arrogant tribes try to fail, otherwise if they successfully capture the mine, what else will happen to us?" Jiang Yuheng said.

"Yes, it's best to wait and see what happens at this time, and we'd better divide our troops into three routes, one way to monitor the movements of the tribe, one way to monitor the movements of the mines, and the last one to closely monitor the reinforcements from the Empire," Han Yunyi said.

"Once the tribal soldiers are defeated, we must step up and take over the battle, and we must not let the empire breathe, even if the jade is burned and the mines are blown up," Yin said.

"It's up to us rangers to go south, drag down the imperial army that came to support, and delay their support, and you are here to wait for the opportunity to act," Han Yunyi said.

"Then please Brother Han," Jiang Yuheng said.

"We have organized all the powerhouses who have reached the Tianmai Realm to reconnoiter the battle situation, and once the tribe fails, our people will immediately go to stop Yao Jingcheng's army," Jiang Yuheng said.

This time, due to the breakdown of the alliance, they also lost the support of the tribe's war eagles, and if they wanted to carry out reconnaissance, they could only rely on the powerhouses of the Heavenly Vein Realm to dispatch.

In Yao Jingcheng's mine, there was a rebellion of hard workers at this moment, these hard laborers these days, their rations were forcibly deducted by Yao Jingcheng, they had to carry out heavy labor every day, but they couldn't eat, everyone was hungry, even the soldiers at the bottom understood the current situation, there was no outside supply of grain and grass, or it wouldn't be long before they themselves didn't need the enemy to attack, and they would be in chaos, and now these hard laborers have been used up, and they have become a burden to the empire, Yao Jingcheng doesn't care about their life or death.

These laborers started a riot, but they were soon brutally suppressed by Yao Jingcheng, and many people died, and they were directly abandoned into the wilderness.

"General, when will our reinforcements arrive, the Horde attacks are threatening us every day, and now we don't have much food and grass?" the general reported.

"Looking for an opportunity, kill all those hard laborers, gather all their grain and grass, we must hold on, the daily food supply is gradually reduced, try to delay time, the tribe's attack has not been smooth in the past few days, there are many dead and wounded people, our solid defense, it is not easy for them to break through", Yao Jingcheng said.

"Yes", the ministry will walk out of the military tent.

The next day, Yao Jingcheng's generals came to the mine with countless soldiers, they gathered all the hard laborers, surrounded them, and used the arcane ** to blow them all up, now these people are just useless waste to them to consume grain and grass, and their rations can buy them a lot of time.

On this day, Shi Xuan and several of the spirit masters who came to investigate witnessed the bloodiest and most violent massacre, the empire blocked the mine, detonated countless arcane **, and countless laborers died on the spot, without even wailing.

Shi Xuan and the others stood on the top of several towering mountains, watching the tragic massacre, they had no choice, the empire was already willing to do anything for the sake of victory.

"Let's go, the only thing we can do is to avenge them, Yao Jingcheng will pay for the blood debt he committed", Jiang Yuheng led Shi Xuan and a few people to quickly disappear on the top of the mountain, and after a while, Yao Jingcheng's spirit master appeared here, and they specially lurked to ambush them.

The tribe's attack did not stop for the heavy sacrifice, they dragged a long front to launch a new round of attack on the empire, both sides left countless corpses in the canyon, such a battle situation can only be described as tragic, these days, there are different voices within the tribe, they are dissatisfied with Harlan Ruoyu's decision-making, the high price is difficult for them to accept, such a fight, even if they win, they will not be able to hold the mine in the future.

Shi Xuan watched the bloody defensive battle on the high mountains on both sides, the long battle line blocked the canyon, the two sides have been fighting along the canyon for many days, although the battle line of the tribe has been advancing, it will also break a lot of towers, and douse a lot of imperial soldiers, but their casualties are not less than theirs.

In some canyon areas, their arcane ** even blew up many valleys, and the fallen landslides buried many people, fighting in these places is simply a nightmare for the steppe warriors, and their wolf cavalry is difficult to play to the advantage.

Without the support of the temporary troops, the tribal shamans were too weakened in their combat ability, and the effect of their actions was extremely weak, and the scale was too small to even destroy the enemy's roots, so that the tribal attack was still attacked by many powerful firepower.

"It seems that if Hulan is determined to attack forcibly, he has no intention of suing for peace?" Zhao Tianhu said as he looked at the tragic battlefield.

This result was beyond Shi Xuan's surprise, he had always thought that the tribe would definitely seek alliance support from them again because the attack was blocked, but he didn't expect them to be so determined.

"It seems that we only have one last way to choose", Lin Zixu looked at Jiang Yuheng.

"Blowing up the mine is the worst option, unless it is absolutely necessary, the head of the sect will not make this decision, and wait, if there is really no turning point, you can only make a decision for the first time," Jiang Yuheng said.

The stubborn resistance of the Shadow Tiger Legion exceeded the tribe's expectations and made them pay a heavy price, but Hulan Ruoyu was unwilling to give up the mining field together, and the tribe's warriors had no choice but to send arrows, and in the past few days, they had advanced the battle line to the vicinity of the minerals, all the way piled up with mountains of corpses and a sea of blood.

Hulan Ruoyu and the leaders of many tribes have already seen the huge mine in the distance, "The decisive battle is coming, warriors, the mountain you see is full of spirit saltpeter mines, as long as you work hard, these are ours, for the glory of Mengtian Khan, even the greatest sacrifice is worth it, without the help of their southern spirit master, we have also come here, what is the great thing about the Shadow Tiger Legion, in front of our tribal warriors, don't want to stop our footsteps", Hulan Ruoyu said.

At this moment, the Shadow Tiger Legion, the morale of the army is still weak, the enemy has come to the door, all the ways out have been blocked, their daily rations are now continuing to decrease, some thin soldiers can't even wave their weapons, and the shortage of food and grass has caused panic.

In the southern part of the Beicang Grassland, the Imperial Army had already been dispatched, but as soon as they arrived in the grassland, they were raided by the rangers led by Han Yunyi, and their food, grass and ordnance were instantly lost a lot, and they were powerless in the face of the shadowless spirit masters who came and went.

The speed of the march was much fuller, and they were creating favorable conditions for the situation in Beicang.

The tribe has not sought support from them, they want to take the initiative at the moment, and the plan to blow up the mine is gradually being raised, but it is extremely difficult to blow up the mine in full view, and it takes a long time to complete the arrangement and many arcane **, which brings them problems.

"It's so hard to blow up such a big mountain, it's not difficult to destroy it simply, but if you want to close the mine permanently, you have to do it on a huge scale, whether it's the empire or the tribe controlling it, they will do everything they can to stop us from carrying out the operation," Lin Zixu said.

"It's really too difficult to rely on the arcane ** alone, and the number of powerhouses in our Heavenly Vein Realm is not enough to carry so many arcane ** to arrange, but maybe Shi Xuan's big map can allow us to complete the task", Jiang Yuheng looked at Shi Xuan.

"Do you want to induce an earthquake in the mountain and collapse it directly?" asked Yin Qianxi.

"Not bad," Jiang Yuheng said.

"If you want to collapse such a big mountain, you have to let the big map exert all its strength to do it, isn't it too difficult?"

"You can't help but underestimate the role of our Spirit Array Master, there is an extremely powerful formation within the sect, as long as we can gather all the spiritual materials, once we are fully urged, it is enough to send the totem Cui to the extreme, maybe let the master give it a try", Chen Tingyu, the first disciple of the Spirit Array Hall, said.

"This matter is up to your Spirit Array Hall to do, what spiritual materials are needed, you tell us, I will let many disciples assist you in carrying out the operation, this time you must close the mine forever", Jiang Yuheng said.

Their action was agreed by Li Dufeng, and He Yizhu also said that he would personally preside over the operation of this spirit array, and Chen Tingyu and many spirit array masters were busy collecting the spiritual materials of this spirit array.
