Deng Ai personally supervised the battle at the foot of the mountain, looking at the sparks dotted all over the mountain, Deng Ai's face was very solemn.

Attacking fortified positions is always difficult to fight, and with such a dangerous terrain, even if he has dozens of times the number of troops, Deng Ai does not expect to be able to solve the battle with a single attack.

What surprised him was that the Shu army actually used a new weapon, an arrow that could be exploded, Deng Ai had been fighting with the Shu army for many years, and he had never seen or heard of the Shu army having such a weapon. Deng Ai repeatedly examined the remains of the gunpowder arrows, which were just ordinary clusters of arrows, except that the bamboo shafts below the arrows had almost been blown apart. The rocket Deng Ai knew that it was to tie a strip of cloth stained with oil on the shaft of the arrow, ignite it and launch it, but these arrows in front of him were a little different from the rocket, not only could burn, but also exploded, although it was not fatal, but it could also cause a considerable degree of damage.

The weapon research and development of Shu has always been ahead of Wei and Wu, such as the Yuan Rong crossbow, the hundred refining knife, etc., so Deng Ai was not too surprised by the appearance of novel weapons. In the eyes of most of the high-level powers of the Wei State, what determines the outcome of the war is the comprehensive national strength, and by no means one or two new weapons, so the high-level of the Wei State has been not interested in developing new weapons, although they also had the genius inventor Ma Jun, who once threatened to create weapons that were five times more powerful than the Yuan Rong crossbow, but due to various reasons, until Ma Jun's death, the research and development of weapons in the Wei State has been in a state of stagnation. The high-level Wei State put their main energy on the improvement of comprehensive national strength, until they thought that they had the advantage of crushing Shu and Wu, so they began to raise troops to destroy Shu.

Deng Ai is also the implementer of this kind of thinking, in his opinion. The Yuan Rong crossbow is no longer powerful. It's just a dead thing. If you want to win a battle on the battlefield, you have to rely on the morale of the army, the quantity and quality of the army, the soldiers of a hundred battles, and the brave army, so that you can be invincible.

"Strange and obscene skills, carving insect skills." Deng Ai threw away the half-crippled arrow cluster in his hand and said contemptuously.

Shi U was responsible for directing night raids. The first wave of attacks was blocked, and he hurriedly replied to Deng Ai: "Dudu, the Shu soldiers are powerful in rockets, and our army has suffered heavy casualties, do you want to suspend the attack." ”

"No!" Deng Ai's face sank like water, "Continue to maintain the momentum of the attack, improve the defense of the shield soldiers, strengthen the countermeasures of the archers, how many casualties in the front, and how much the reserves in the back are replenished." ”

"No!" Shi Su did not dare to disobey. Immediately turned around and went down and directed the army into a second wave of attacks.

There is no intrigue to play in the battle. It is completely real and real strength to fight, Deng Ai has fought countless battles, in terms of experience, there is no one better than him, in the case of his own strength, only with continuous attacks to create a sense of oppression for the enemy, in order to mentally crush the enemy. The battle is a war of attrition, which is the same for both the offensive and defensive sides, but the attacking side has to pay a greater price than the defending side, but Deng Ai doesn't care, with twenty or thirty times the enemy's strength, no matter how big the casualty price is, he can bear it.

The defenders on the mountain were different, there were only a few hundred people in total, and the casualties were one by one, as long as the pressure on the mountain was continuously exerted, Deng Ai believed that it would not be long before they would collapse. To put it bluntly, the battle is a contest of spirit and willpower, whoever can resist to the end will be the winner, and those who can't resist will be the first to collapse.

For Deng Ai, the biggest difficulty is not the lack of troops, but the lack of time, his grain and grass can not support a few days, if he can't take Jingjun Mountain as soon as possible and seize Jiangyou Pass, his army may starve to death on the Yinping Trail, so Deng Ai needs to open up the Yinping Road at all costs, people block killing, and God blocks killing God.

Zhao Zhuo also felt a trace of pressure, the Wei soldiers were not afraid of death, and launched wave after wave of offensives one after another, for these family soldiers, it was indeed a test, although the quality of these family soldiers was good, but they were used to being pampered, they had never experienced such a baptism of blood and fire, in the face of such a high-intensity bloody battle, the consumption of physical strength and energy was huge, and after four consecutive hours of fighting, they were almost exhausted.

Liu Yin's rotation combat plan is obviously very effective, if all the troops are put into the front-line operation, at most one day, I am afraid it will be difficult to continue, and the combat time of each group of four hours can be said to be just right, the physical strength and energy are exhausted, and the next group of people will immediately take over, so that the strong combat effectiveness can be maintained.

The attack of the Wei army reached a high tide during the day, looking from the top of Jingjun Mountain, the entire rugged mountain road was densely packed with layers of Wei troops, such as ants gathering, such as locusts, all over the mountains, mighty, banners covering the sun, war drums rumbling, shouting and killing shook the clouds.

Liu Yin couldn't help but be deeply shocked, Deng Ai's ability to govern the army is really extraordinary, even on the bumpy mountain road, the Wei army is still neat and orderly, the soldiers in front of them fall, the soldiers behind will not hesitate to make up, the whole army, just like a well-constructed war machine, is advancing in an orderly manner, like an unstoppable torrent, going against the mountain, sweeping everything.

The various branches of the Wei army skillfully cooperated with each other, braving the rain of arrows and stubbornly advancing forward.

The shield soldiers formed a dense phalanx, with shields on their heads, each shield was closely connected, and there was hardly a gap to be seen, forming a huge shield, even if one of the shield soldiers was killed by random arrows, the shield soldiers behind would rise up as if they were on the ground, and the entire giant shield always maintained its intact appearance, moving slowly but firmly towards the top of the mountain.

Auxiliaries carried sandbags on their shoulders and built temporary defensive bunkers on both sides of the path to provide shelter for archers.

The Wei army also used bed crossbows - God knows how Deng Ai brought this ultra-long-range assault weapon to Yinping Trail, probably this bed crossbow is a detachable equipment - the huge arrows made a loud noise, whistling towards the top of the mountain, and all the targets it hit were easily destroyed, and even the heavy stone wall was swaying when it was hit by the crossbow arrows.

The battle on Jingjun Mountain has reached a white-hot level, and the entire mountain road is already covered with countless corpses of Wei soldiers, and the Wei soldiers who came up in the follow-up are completely stepping on the corpses of the robes.

The casualties of the family soldiers were increasing sharply, Liu Yin was worried, and ordered: "Prepare grenades!" (To be continued......)
