Although the Zhao army of the Jingcheng battalion attacked, it did greatly limit the attention of the Qin army, but Wang Jian did not weaken the Qin army's investment in the relief line, and the ten Qin army patrol teams were still patrolling back and forth on the relief line, of course, the Qin army also had enough troops to protect its own relief line, and the transportation team also stepped up the distance, after all, in the first two months of the attack, the Qin army also lost a lot of supplies. Therefore, it is also necessary to seize the time to replenish.

Of course, during this period of time, Wang Jian did not think that such a passive response to the attack of the Zhao army was very unfavorable to the Qin army, and the Qin army must find an opportunity to take the initiative in order to regain the initiative on the battlefield, at least not let the Zhao army fully grasp the initiative on the battlefield.

However, the Zhao army can attack the Qin army's relief line, but the Qin army cannot be brewed in the same way, the reason is that the Zhao army occupies an absolute geographical advantage, and the rolling Taihang Mountains block the Qin army's circuitous route, so that the Qin army cannot go around the rear of the Zhao army to destroy the Zhao army's supply line on a large scale like the Zhao army's cavalry, which is also the innate advantage of the Zhao army.

Of course, the Qin army is not completely without opportunities, but another important factor is the concept of the Qin army, because in ancient China, until the period of Emperor Wu of the Han Dynasty, in the war between the Han Dynasty and the Xiongnu, the cavalry officially stepped on the stage of China's war as the main force of the army, and the concept of large-scale and large-distance cavalry mobile combat appeared. If the commander of the Qin army was Bai Qi back then, or Li Mu now, he might dare to make a bold attempt, but Wang Jian is not the kind of famous general who can create new tactics, and has always been known for his prudence in the use of troops, so it is indeed difficult for him to take the risk of adopting the tactics of the Zhao army without enough certainty.

In this case, it was difficult for Wang Jian to find a way for Qin Jun to get rid of passivity and master the initiative, so Wang Jian could only respond to Zhao Jun's actions step by step. However, under every blow of the Zhao army, the Qin army was able to find a way to deal with it, on the one hand, it was Wang Jian's ability, and on the other hand, it was also the support of Qin's strong national strength.

However, the fourth attack of the Zhao army presented a new problem to the Qin army.

The fourth sortie of the Zhao army, the strength of the army was quadrupled, theoretically speaking, it was possible to attack the transport teams of the four Qin armies at the same time, although the Qin army had ten patrol cavalry troops, but it was also impossible to prevent it, sometimes in order to rescue a transport team, several Qin troops would arrive, but sometimes a transport team would be attacked by two Zhao armies.

Moreover, this time Zhao Jun also changed his strategy, not for the purpose of urging the destruction of an entire grain transportation team, as long as it can urge the destruction of a part of it, although tactically speaking, it is better to cut off the enemy's fingers than to hurt the enemy's ten fingers, but for the attack on logistics, it is far stronger to be able to attack ten logistics teams than to only destroy one logistics team. Later, the Zhao army even invented a new tactic, that is, first attack a transport team, attract the surrounding Qin army patrols to rush to the rescue, and then quickly evacuate, immediately look for the next target, and hit a time difference, during the fourth attack of the Zhao army, this trick was also tried and tested, and later became the main tactic of the Zhao army.

And the most important point is that the Zhao army has attacked three times before, each time there is a certain time limit, because the Zhao army is lightly armed and can't carry too much dry food, so the Zhao army's sortie time is generally between seven days and ten days, after the end of a sortie, there will be a period of about five days of stable area, plus two or three days before and after, the activities of the Zhao army will not be too much, and the Qin army can often take advantage of this time to step up the transportation of a batch of materials. Because it was during the third attack of the Zhao army, the Qin army stopped the departure and transportation team for a while.

But this time it was different, because the Zhao army was divided into two batches, taking turns to attack, at least two cavalry armies were on the battlefield at every moment, and the time was basically unlimited, which caused a lot of trouble to the Qin army, at first the Qin army also stopped setting off to transport the team, but after waiting for a few days, it was found that the Zhao army did not stop, ten days later, the Zhao army was still there, and after twenty days, the Zhao army did not leave, at this time the Qin army finally determined that this time the Zhao army was indeed different.

As a result, this attack lasted for more than a month, and the Qin army's transport team to the front line battalion was reduced by nearly forty percent, and eighty percent of the transport team was attacked by the Zhao army, and more or less suffered some material losses.

In addition, during this time, the Zhao army continued to attack the Qin army on the frontal battlefield, so the Qin army also consumed a large amount of ordnance and materials, and the three Qin army battalions stationed in Jingcheng were not enough to support a month's time.

If the previous attacks of the Zhao army were only possible and possible to threaten the Qin army, then this time the threat to the Qin army is real, if the Qin army does not take new countermeasures, then at most the Qin army can only hold out for another month, and then the Qin army will have to take the initiative to withdraw without the Zhao army coming.

But now the Qin army really has no good way to deal with it, and Wang Jian also has to increase the number of troops, first of all, to expand the size of the patrol team, the number of patrol teams to twenty, and along the way from Qiu You to Jingcheng, set up twenty-seven camps, and camp on the spot. Of course, in this way, the Qin army's troops invested in protecting the relief line also rose sharply, and finally a total of 150,000 troops were invested, and the supply line was finally opened through the new, and at this time, the Qin army's supplies were less than five days. A lot of supplies have been used up.

Fortunately, the Qin army in each battalion had stored a large amount of food, so that the Qin army would not go hungry, but at this time, the Qin army's food was less than half a month, and if the supply line was not restored, the soldiers of the Qin army would use measures to reduce rations.

However, in this way, it also caused a large reduction in the strength of the Qin army in the frontal battlefield, only more than 200,000 troops, and it also dealt a considerable blow to the morale of the Qin army.

At this time, the Zhao army completed a rotation of troops, Li Mu dispatched 100,000 troops, with the 60,000 fresh troops who had just arrived at the camp in Jingcheng as the main force, and launched a fierce attack on the camp of the Qin army, which was also the first time that the Zhao army officially launched an attack on the Qin army in a decisive battle with the Qin army since the two sides began more than four months.

Although the generals of the Qin army all believed that it was not appropriate to enter a decisive battle with the Zhao army at this time, after all, it was not the best state of the Qin army, and the Zhao army still had two cavalry armies and infantry armies with strong combat effectiveness, so they should stick to it without fighting, relying on the stable camp established some time ago to resist the attack of the Zhao army, Bi Hao Zhao army can only dispatch more than 100,000 troops now, and the Qin army can completely defend it. But at this time, Wang Jian was strong against public opinion, and firmly believed that at this time, the Qin army must go out of the camp to meet the Zhao army.

Because in the previous stage, the Zhao army's attack on the Qin army's replenishment line deeply affected the morale of the Qin army, if at this time, the Qin army closed its doors and did not fight, it will further hit the morale of the Qin army, although the Zhao army can only dispatch more than 100,000 troops in the Jingcheng battalion, but at most three days, the Zhao army can mobilize more than 100,000 troops from Quyang and Fanwu to participate in the battle, so that the strength of the army will be more than doubled in a short period of time, and after a period of recuperation, morale is high, and at that time, Will the Qin army still be able to withstand the attack of the Zhao army?

Therefore, at this time, the Qin army must go out of the camp to meet the Zhao army and fight a fierce battle with the Zhao army, so that the Zhao army also makes Li Mu clear that the Qin army still has the strength to fight, and it is not possible to be defeated lightly. And although the Zhao army does have two cavalry and infantry armies with extremely strong combat effectiveness, judging from the current situation, the number of these two armies is not large, and they may be able to play a great role in the battle of 350,000 troops. But in a battle at the level of a hundred thousand troops, the role it can play is much smaller.

Moreover, in the several advances of the Zhao army attacking the Qin army's replenishment line, the cavalry army was used to fight the main force, although good results were achieved, but this cavalry army would definitely suffer certain losses, and at the same time it was very tired, and in this battle, it may not play much of a role, and there is no need to be afraid.

After listening to Wang Jian's analysis, all the generals were also very convinced, and of course they agreed with Wang Jian's decision to face the Zhao army, and at the same time, they all asked Wang Jian to fight, and wanted to fight with the Zhao army, so that Zhao Jun knew that the Qin army was by no means easy to mess with.

So Wang Jian also mobilized 150,000 Qin troops and went out of the camp to meet the Zhao army, and as a result, the two sides conducted three large-scale engagements in a row in seven days. Li Xin, Xin Sheng, Qiang Kui and other main generals of the Qin army all personally hung their armor and went into battle to boost the morale of the Qin army, so although the Qin army was slightly inferior in the scene, and the number of soldiers killed in battle was also more than that of the Zhao army, they were never defeated by the Zhao army. Of course, the superiority of the Qin army in soldiers was also an important factor.

As a result, after these three battles, the Qin army lost more than 30,000 casualties, nearly 20,000 soldiers were wounded, and more than 500 chariots were destroyed. The Zhao army was no better, with more than 17,000 soldiers killed, nearly 15,000 soldiers wounded, and nearly 400 chariots destroyed.

In this case, Li Mu did not dare to consume the Qin army like this, so he had to collect his troops and return to the camp to stop this battle. At the same time, I have to sigh that the Qin army is indeed difficult to deal with, and Wang Jian is indeed worthy of being the first general of the Qin State and a strong opponent.
