Li Hun at this time has also found the weakness of Tongguan from the drawings of the construction of the pass two years ago, he ordered the soldiers to dig the ground and dig a well in about 300 steps outside the pass, the terrain of Tongguan is high, their terrain is low, once they open the well, then the well water in Tongguan will naturally flow into their well, there are 50,000 people in Tongguan, it is very difficult to get water, if they cut off their underground water source, the Tang army will be in chaos without a fight. Pen, fun, and www.biquge.info

After Li Shimin discovered the movements of the Sui army, he was also surprised, after the Sui army came down to the pass, the first thing was to cut off the waterway between Tongguan and the Yellow River, making it difficult for the defenders to take water, but there are still a lot of wells inside Tongguan to support, plus the Yellow River flows through here, there must be no shortage of groundwater, so although the water source is tight, it is not fatal, but Li Hun actually ordered to dig a well outside Tongguan, this is not to cut off the water source of Tongguan?

Li Shimin immediately led the troops out of the pass, wanting to destroy these wells, Li Hun had already prepared, and immediately led the army to fight, the Zhichong Army and the Guoyi Army were the most courageous troops in the empire, plus they had already prepared, Li Hun in order to deal with the cavalry of the Tang Army, specially built more than 100 bed crossbows, these large crossbow arrows can be shot into the city wall, and the face of the cavalry is as simple as chopping melons and vegetables.

Li Shimin's army just went out of the city, and before it had time to gain a firm foothold, it was attacked by the other party on both sides, coupled with the bed crossbow that shot from the front, the Tang army was suddenly defeated, Li Shimin saw that the situation was not good, and hurriedly withdrew to the city, and the Tang army scrambled to retreat into Tongguan, if it were not for the bows and arrows on the city wall were too dense, the cavalry of the Zhichong army would follow the defeated army into Tongguan in one go.

This battle lasted for a very short time, before and after only a stick of incense, the Tang army had already paid the price of nearly 3,000 casualties, if it was not for Li Shimin's timely order, when the cavalry of the Zhichong army outflanked and besieged the Tang army, I am afraid that the more than 10,000 people brought out by Li Shimin would have been folded there.

The combat effectiveness of the Sui army is so strong, this battle is not easy to fight, it seems that they can only attack after the Yuanba and their side have made progress!

After Li Shimin experienced a setback, he learned a lot, and he ordered Guannai to hurry up and fill up the water and store it so that it could support it for a few more days.

Li Hun was naturally very happy to see that his first battle greatly frustrated the spirit of the Tang army, and also killed more than 3,000 enemy troops, and he immediately sent a good report to Emperor Yang of Sui, saying that he would defeat the Tang army and defeat the army, and Tongguan City would soon be taken.

Just before Li Hun could be a little more happy, a bad news came, his rear army's baggage troops were attacked by the Tang army, and the army suffered heavy losses and asked for reinforcements.

Li Hun was taken aback, his grain and grass were all on the road, if the grain and grass were burned, then his army would definitely collapse faster than the Tang army in Guannei!

Li Hun led the army and hurriedly rushed to the rear army to prepare for support, but as soon as their side moved, the Tang army in the pass also moved.

Li Shimin learned the lesson of the previous time, and kept the army at a distance of about three hundred paces, at which the Sui army's bed crossbows were not lethal enough to pose a threat to them.

Li Hun left Guoyi's army here to resist Li Shimin, and his own commander broke the army and galloped eastward, preparing to rescue his baggage troops.

Seeing the thick black smoke coming out of the rear from a distance, Li Hun became more and more anxious in his heart, he kept urging the army to advance, and gradually he separated from a group of cavalry and infantry around him, and the cavalry was the majority of the Chong army, so Li Hun didn't care, they galloped into a valley, and saw the Sui army flags and armor scattered everywhere outside, Li Hun didn't think too much, and directly led the army into the valley, because he knew that the other party could quietly touch the back of his army, then their number must not be very large, Therefore, even if he encounters an ambush, he is not afraid.

It's just that after arriving in the valley, there was a short, thin-looking, dark-faced soldier on the road in front of them, who was wearing a pair of Tang Army armor and holding two purple gold iron hammers the size of a stone mill in his hands.

"Who are you, dare to stand in the way of the general, if you don't want to die, get out of the way!"

Li Hun saw that the other party was not good-looking, and he didn't care much about him.

Li Yuanba looked at them and said, "I heard that you are very capable of fighting, I don't know which one, you let him stand up, as long as he can beat me, I will let you go!" ”

Li Hun sneered, just such a half-sized boy, his hair has not grown, and he is still learning to fight with others, you think this is in the street market, and he is one-on-one with you, this is on the battlefield.

"The archer will give me arrows and shoot him!"

Li Hun didn't want to waste time, so he directly ordered the archers to fire arrows at Li Yuanba.

The archers of the Sui army aimed dozens of bows and arrows at Li Yuanba not far away, only to hear the buzzing sound of a bowstring, and a black rain of arrows flew straight towards Li Yuanba like lightning.

Li Hun snorted coldly in his heart, no matter how high your martial arts are, under the attack of a bow and arrow of such strength, you must be dead without a place to be buried!

It's just that the development of things doesn't seem to be as he wants, Li Yuanba waved the sledgehammer in his hand, and it didn't seem to be very fast, so it looked like a heavy sledgehammer, and he couldn't think about it quickly, but in the eyes of everyone, this slow to the extreme, actually dialed down the twenty or thirty arrows that flew over one by one, and none of the salvos hit, which made everyone extremely surprised, and looked at Li Yuanba with an incredible face.

"Why do you shoot me with arrows, my brother told me that those who shoot arrows at me are bad people, you are bad people, you deserve to die!"

Li Yuanba was obviously enraged, he urged the war horse (I didn't want to set up a war horse for Li Yuanba, because his weight plus the weight of the war hammer in his hand is more than 1000 catties, such a weight of any war horse is estimated to be crushed to death under his crotch, but if you don't set up a war horse for him, you can't ask him to run on the ground and fight with others, he is not tall, his legs are short, he can't run fast, then the fight is not good) roared, and made an earth-shattering sound to kill the Sui army.

Li Yuanba's roar echoed extremely loudly in the valley, Sui Jun was just stunned by the scene where he dialed the feather arrow, at this time seeing his roar as loud as thunder, it was comparable to Zhang Fei's shocking roar on the Changban slope, and there was an instinctive fear in his heart, and Li Yuanba's image in their hearts seemed to have changed, from the previous short image, Shun became a lot taller.
