At first, no one knew when the water in the leak would be dripped, because according to Cao Liang's request, every time the messenger appeared, the leak would stop counting, refill with water, and start counting again.

Normally, the messenger does not come every day, most of the time, it appears once every two days, which means that before the water in the leak is dripped, the messenger will appear and let the leak start the timer again.

There was only one exception, and two days had passed since then, and the messenger had not yet appeared, so that Yanghu Deng Ai Shibud was like a great enemy, and they were all ready to go.

However, it turned out that it was just a false alarm, and the messenger who came to deliver the message encountered an unexpected situation on the way, so he was delayed for half a day and was late.

In fact, although Cao Liang sent messengers two days apart, due to the constant accidents on the road, the time of arrival of these messengers was different each time.

But in general, it takes about two days for each messenger to appear, and at first Yanghu and the others were very interested in this thing, and they didn't use these object needles again, so they were really curious.

But after a long time, the freshness of Yanghu and the others faded, and they felt that this thing was too draining of people's spirits, and no one knew when the coup d'état would take place in Luoyang, so they could only rely on this leak to calculate the time, and the time of the first day would be relatively stable, but on the second day, the mood became apprehensive, and if it did not exceed the usual normal time, everything went smoothly.

But once this point is exceeded, but the messenger has not yet appeared, everything will be different, and all the people's spirits will begin to be highly tense, and their eyes will not take off the leak for a moment, until the messenger appears, and the tense nerves are relieved, and then the next round of tension will be carried out.

And this time, on the third day, the messenger did not appear again, and all the people's spirits were highly tense, staring intently at the leaker, and all the subordinate armies had already completed their assembly, waiting for the moment when the leak was exhausted.

But no one knows if this is the last time, maybe the moment when the water in the leak is dripped, there will be a messenger coming, and then zero and restart.

It wasn't until the last drop of water fell in the leak that Yanghu and the others finally understood that Sima Yi had already launched a coup d'état, and it was time for them to attack.

According to the prior agreement, once the leakage is exhausted, the first 5,000 Yue cavalry and 5,000 tun cavalry will take the lead in attacking, and the 5,000 infantry of the infantry battalion will go to Shimen Pass under the leadership of Yanghu to respond.

In fact, it has been more than two days since the rebellion in Luoyang City broke out at this moment, and in these two days, what happened, Deng Ai and they naturally didn't know anything, only by speeding up and entering Hanoi County, and even reaching Luoyang, could they get the answer they wanted.

For the two battle-hardened armies, the Viet Cavalry Battalion and the Tun Cavalry Battalion, their sorties were orderly, and their first target was Shimen Pass, which was located at the junction of Shangdang and Hanoi.

Hu Fen is stationed in Shimen Pass, but the number is only about 100 people, his purpose is just to set up a checkpoint in Shimen Pass, block traffic, and want to block the torrent of 10,000 iron horses, which is completely a fool's dream.

These hundred or so people saw the black and suppressed Bingzhou Iron Cavalry roaring, and they suddenly became messy in the wind, and they all trembled, not to mention fighting, they didn't even have the courage to lift their weapons.

Deng Ai briefly interrogated the captives, and sure enough, it was not much different from what he expected, these soldiers were ordered by the Hanoi Taishou Hu Fen to set up a pass here to block all the journeys that passed.

As for the rest, they don't know anything.

After capturing Shimen Pass, the Yue Cavalry Battalion and the Tun Cavalry Battalion faced more targets, whether to attack Zhihuai County, the county of Hanoi, or Sima Yi's hometown Wen County, or to go directly south, cross the Yellow River and take Luoyang, all of which were issues that Deng Ai needed to consider.

However, the biggest difficulty now is to find Cao Liang's whereabouts, now that the coup has happened for two days, Luoyang is bound to be turned upside down, whether Cao Liang is still staying in Luoyang, Deng Ai is unknown, so after entering Hanoi, Deng Ai decided to get in touch with Cao Liang first to determine the next action target.

Deng Ai discussed with Shi Bao and decided to go south immediately to Xiaopingjin Ferry, if Cao Liang escaped from Luoyang, then Xiaopingjin was the only way for him to return to the state. If Cao Liang is still stranded in Luoyang at the moment, waiting for rescue, then crossing the river from Xiaopingjin to the south has become their best choice.

Therefore, Xiaopingjin became the key to this battle, so the Yuecai battalion and the tuncai battalion went directly south and rushed to Xiaopingjin for a long distance.

In the process of going south, Deng Ai also sent out a lot of scouts to expand the area of reconnaissance to the surrounding thirty miles.

According to the scout's intelligence, Deng Ai learned that most of the troops of Hanoi County were gathered in the area of Ha Duong, which couldn't help but make Deng Ai a little strange, it stands to reason that Ha Yang is just a small county, not a strategic place at a dangerous pass, why did Hu Fen deploy his troops to that place?

Unless there is something in Heyang that attracts Hu Fen's army, could it be that Cao Liang and others have already crossed the Yellow River and are trapped in Heyang?

In any case, since a large number of Hanoi soldiers were found in the area of Heyang, Deng Ai must first consider annihilating him, otherwise crossing the river to Luoyang will be a hidden danger after all.

The soldiers of the Yue cavalry battalion and the tun cavalry battalion divided into two routes, went straight to Heyang, and after approaching the target, they did not give Hu Fen any chance at all, and directly launched an attack.

At this moment, the Hanoi soldiers and the Sima soldiers were thinking about how to attack Heyang, but they never thought that the Bingzhou cavalry had come from behind, like a storm tornado that suddenly blew between the flats, sweeping and sweeping.

The Hanoi soldiers and the Sima soldiers are infantry-based troops, compared with the strong and brave Bingzhou cavalry, it is simply a in the sky, one on the ground, the combat effectiveness of the two sides is not on a horizontal line at all, in the blink of an eye, the Bingzhou cavalry has broken through the outer positions of the Hanoi soldiers, and continues to advance unscrupulously.
