Beginning in May, military newspapers from Lingnan were sent to Xianyang by expedited delivery of 400 miles.

The five-way army commanded by Wang Ben, the Marquis of Tongwu, swept through Lingnan like a broken bamboo, and countless Yue tribes surrendered or abandoned their villages and fled.

At the end of May, Ren Huan occupied Panyu, captured the king of Nanyue, and the surrendered troops reached more than 30,000 people, and the country of Nanyue was destroyed.

At the beginning of June, Zhao Tuo led the army to break through the old nest of Dongou entrenched, and the king of Dongou knelt down, and the tribes that surrendered with him reached more than 50,000 people, and the Dongou country that had been entrenched in Lingnan for hundreds of years was destroyed.

In the middle of June, Wang Ben personally commanded the two armies respectively to break through the Wang Ting garrison of Xiou and Luo Yue, and beheaded the Luo Yue Wang Ligong who swore not to surrender, the Luo Yue tribes scattered and fled, most of them retreated to the deep mountains and mountains in the southwest of Qianzhong County, because the road was rugged and precipitous and could not catch up, Wang Ben packed up his troops to occupy the Red River Valley, and set up the county government to move to the prisoners and the local Yue people to live together and garrison.

Wang Yihu Song also refused to surrender, and Wang Ben's army was defeated and retreated in several battles in succession, but because he was familiar with the terrain in the southern mountains, he drove wild beasts and tribes to constantly harass the Great Qin army, resulting in the Qin army began to have a lot of casualties, and at the same time, because of the hot and humid climate in summer, diseases and plagues began to appear in the Qin army, Wang Ben decided to temporarily withdraw his troops and wait until autumn to attack Xi'ou, but before retreating, Wang Ben specially asked Han Xin's opinion.

Although Han Xin was young, he was smart and quick-witted and familiar with the art of war, and he had extraordinary insight into marching and fighting, and he had put forward a lot of fruitful suggestions in many battles to conquer Lingnan, and he also won a lot of victories, so Wang Ben was not stingy, and after each battle, he would always write down a military merit for Han Xin, and his identity was also promoted from an ordinary retinue to the commander of the army, and he had the status and identity of really participating in making suggestions, and became a real Daqin official.

Since the general asked, Han Xin, who already had his own views on the march and fighting, put forward a different opinion, believing that although the current Great Qin army was injured and sick, and the water and soil were not adapted, the army as a whole was stable, the supply of grain and grass was sufficient, and the morale of the soldiers was very high. After driving them to a certain place, they used Taiyi Divine Thunder to carry out an unprecedented divine thunder bombardment to completely break the resistance of the Yue people.

Taiyi Divine Thunder is very powerful, but Qinghe Marquis has never allowed it to be used on the battlefield, I heard that the First Emperor also asked Qinghe Marquis whether he could use it against the enemy, but was rejected by Qinghe Marquis, saying that it was too hurtful to the heavens, and when Xianyang released the Divine Thunder Fireworks for the first time, Wang Ben also asked the emperor if he could use this terrifying immortal spell on the battlefield, but the emperor also refused.

But after seeing the power of the Taiyi Divine Thunder to open the mountain and blow up the stone, Wang Ben is naturally still ready to move, but these Taiyi Divine Thunder belong to the Academy of Sciences, and the Academy of Sciences is not subordinate to the Ministry of War, and Wang Ben has no right to command, so he has always been very regretful.

At present, Wang Ben also knows that it is not the best time to withdraw the army, it took nearly three months to finally fight here, the largest Yue tribe in Lingnan, Xi'ou, has not been conquered, and after the retreat, the Xi'ou tribe will inevitably make a comeback, and then it will take a lot of effort, and the consequences are not very predictable.

The terrain and climate of the Lingnan regions are complex and changeable, far beyond Wang Ben's expectations.

If it weren't for the fact that the spiritual canal was built and a large amount of grain, grass and medicine were continuously replenished, it is estimated that it would take at least a year more to achieve the current effect.

Therefore, Wang Ben naturally recognized Han Xin's strategy, and assigned Han Xin to contact the craftsmen of the Academy of Sciences to see if he could use the remaining Taiyi Divine Thunder.

It is Hu Kuan and Shi Lu who presided over the construction of the Ling Canal, although the main canal of the Ling Canal has been repaired, and the boats have been able to travel between Xiangshui and Lishui, but in fact, the passage is not very convenient and smooth, because the water level difference between Xiangshui and Lishui is too large, and the water flow is turbulent at the intersection and the bend is too rapid, and the boat will capsize when entering the Lingqu from Xiangshui accidentally, so even if the war to conquer Lingnan has been going on for several months, the army that repaired the canal has not all been evacuated. Instead, he continued to use 20,000 men and prisoners to build an auxiliary canal about several miles long at the intersection, so that the water level could be lowered and stabilized, so that boats could come and go.

In order to build this spiritual canal, Chen Xu asked the craftsmen of the Nanshan Courtyard to continue to make gunpowder, and every month several cars had to be transported to Lingnan to replenish, and now the canal repair has come to an end, and the explosives are naturally still left at the canal repair site, and all the ones that cannot be used up will be transported back to Xianyang and handed over to the craftsmen of the Nanshan Courtyard to be counted and sealed into the warehouse, and half of them cannot be left out.

For the control of gunpowder, Chen Xu is the most strict and careful.

Without his permission, no one can get close to the Nanshan Annex, and the guards inside are now replaced by teenagers from the musket team, and any suspicious person who approaches will be killed, and only two dumb slaves know the recipe and production method of gunpowder from beginning to end, and the other craftsmen will only use it and not make it.

Firecrackers, fireworks, grenades, guns and bullets made of bamboo pipes, etc. are all secretly developed in the Nanshan Annex, and there are more than ten craftsmen in the development of muskets and artillery, Chen Xu will occasionally go to inspect and guide, but no one in the outside world can know what the situation is inside, and they don't even know that there is such a thing as gunpowder in the Nanshan Courtyard.

The two dumb slaves make gunpowder in a separate room, and the remaining craftsmen who develop guns are in another yard, and if they successfully make gunpowder and qualified gunpowder grenades, there will be a separate person responsible for putting them in the basement and enthroned them, and the craftsmen don't know where to put them, and the young man of the musket team is only responsible for safety, and he doesn't know how many guns and bullets are stored in it, and every time he transfers gunpowder and gunpowder, he must hold Chen Xu's token and warrant, and the numbers must match completely, After several inspections and checks, the carriage was tightly covered and pulled out.

Therefore, although gunpowder is a common thing Hu Kuan and Shi Lu, all the craftsmen and craftsmen involved in the blasting know the importance of gunpowder, and they also know the principle of secrecy of Qinghe Hou for gunpowder safety, and generally never discuss any topic about Taiyi Shenlei in private.

However, this time, Hu Kuan, Shi Lu and a group of craftsmen from the Academy of Sciences were in a dilemma.

Because it was none other than Han Xin, the younger brother of the Marquis of Qinghe, who came to ask for gunpowder.

Although Han Xin's identity is only an unknown relative of the Marquis of Qinghe, Hu Kuan, who is familiar with the situation in the Marquis of Qinghe's mansion, knows that the Marquis of Qinghe is very important to the younger brother that his father picked up from outside, and he also has high hopes, otherwise he would not have sent him to the Marquis of Tongwu so early to learn to march and fight, and I heard that Han Xin was a young man who was smart and deeply valued by the Marquis of Tongwu.

Therefore, for Han Xin's request, Hu Kuan was so depressed that he almost wiped off the beard on his chin.

Promise, once Qinghe Hou knows about it, this black cauldron will have to be carried by himself.

But don't agree, this is Qinghehou's younger brother, and in the future, he can put on small shoes in front of Qinghehou with a casual word, and he still has no words.

Han Xin was also very worried.

This time with Wang Ben first suppressed the Xiang rebels, and then commanded 200,000 troops to attack Lingnan, for the young man, it is definitely a major sublimation of life experience, in just two years, he liked to follow a group of boring classmates and gentlemen in Xianyang all day long in Xianyang Quyuan Miscellaneous House drinking cockfights and bowing bad habits have been wiped out, the current Han Xin is seventeen years old, in addition to the long handsome and tall many, the immature face of the past has faintly had a kind of maturity and coldness, Speaking and acting with a degree of vigor and resoluteness, he began to have a bit of military momentum, wearing leather armor and carrying a long sword, standing quietly in front of Hu Kuan, which made Hu Kuan feel a huge pressure.

But this kind of pressure Han Xin himself can't feel.

Because Hu Kuan is not an ordinary person, he was the first to follow his brother Qinghe Marquis, although the title is not high, just a middle doctor, the official position is not high, just an ordinary position, but this guy is the vice president of the College of Engineering, the director of the experimental factory of the Academy of Sciences, the master builder, almost all the waterwheel mills in the country were built in the hands of Hu Kuan, and he is really the most important right-hand man of the Qinghe Marquis, and his status is comparable to Zhang Cang.

Moreover, Hu Kuan is also the most loyal dog leg of his brother Qinghe Hou, and he is not wrong with Qinghe Hou's orders.

For this battle to conquer Lingnan, Han Xin began to have great interest, but after being stationed in Lingnan for more than a year, he began to can't bear it anymore, Lingnan is a broken place is simply not a place for people to stay, the mountains are high, the forests are dense, the river network is dense, damp and rainy, and there are piles of mosquitoes, and every extra day feels like a torment, so he has long hoped that this war will end as soon as possible.

If Wang Ben commands the army to retreat, and when the weather is cool in August and September in the autumn, the river subsides and launches an attack again, maybe this battle will be fought until next year, and the more southwest the attack, the more complex the terrain and terrain, according to the habits and urine of the people of Xiou who are like savages all over the mountains, maybe this war will not end next year.

If that were the case, he would continue to stay in Lingnan for a long time.

Uncles can tolerate aunts, and piles of mosquitoes in Lingnan are even more unbearable.

Han Xin felt that since there was such a good thing as Taiyi Divine Thunder, why couldn't he take it out and use it, he had seen the power of firecrackers and grenades, and he could almost use his ass to think of the outcome after using Taiyi Divine Thunder, and the Yue clan such as Xiou and Luo Yue, who were stubbornly resisting at the moment, would definitely collapse in an instant in the roar of Taiyi Divine Thunder, and the barbarian chief Song would definitely be frightened and pull his pants.

Therefore, at the moment when Wang Ben had the intention of withdrawing his troops, Han Xin decided to drag this war into a decisive battle as soon as possible, completely pacify Lingnan in one go, and then ...... He will never come to the ghost place of Lingnan again in his life.

As for Han Xin's strategy, Wang Ben finally decided to adopt it after careful consideration, but the premise was that Han Xin could get Taiyi Divine Thunder.

If there is anyone else in the entire southwest military camp who can handle this matter, there is no one else but Han Xin.

Therefore, Wang Ben is also full of apprehension and expectation.

Although he is the military god of the Great Qin Empire, as one of the few marquis of Che, he has made great achievements and has also made great achievements, Wang Ben deeply remembers the repeated entrustment of his father Wang Jian after accepting the edict of the first emperor to take charge of the southern army, don't be arrogant, don't do it without orders, let alone rejoice in it, and would rather lose the battle than forcibly snatch the credit, because the three generations of the Wang family have too many merits, so much that the emperor is afraid of them.

But Wang Ben has always been a commander who never gives up, it is impossible to defeat the battle, and it is even more impossible to admit defeat, the six countries have been swept away by their father and son, and now in the face of the Xiou barbarians with only tens of thousands of people, if the conquest fails, Wang Ben feels that he is indeed a little unable to pull down.

Although the retreat is a little helpless, and it is also in line with his father's arrangement, but from the heart, Wang Ben is still a little resistant, this may be the last chance for him to serve the emperor in his life, and it is also the last time to lead the troops to fight, he hopes to draw a perfect end to his military career with a perfect ending battle, so that he will not leave a lifelong regret.

But in the face of the cruel climate and complex environment of Lingnan, if you want to have a perfect ending battle quickly, the best way is Han Xin's strategy, and use the Taiyi Divine Thunder to completely break the courage of the Lingnan Yue people, and then the Lingnan lands can be easily conquered.

However, it is difficult to use the Taiyi Divine Thunder, Wang Ben himself has thought about it countless times before, but he finally gave up his mouth, because the Taiyi Divine Thunder is not even willing to talk about it easily by the emperor, this is the immortal method of the Qinghe Marquis, without the permission of the Qinghe Marquis, once the forcible action is used to offend the Qinghe Hou, it is more disturbing than offending the emperor.

And right now, Han Xin volunteered to jump out, which was actually in line with Wang Ben's intentions.

He not only wanted to conquer Lingnan quickly, but also wanted to see the power of Taiyi Shenlei against the enemy.
