Xiong Tingbi looked through the telescope for a moment, then gave the order in a deep voice, "Order the artillery to prepare for the bombardment, and when I give the order, bombard the enemy fiercely."

The messenger bowed in response, trotted down the platform, and went to deliver the order.

At this distance, the Red Cannon, which fires solid shells by ricocheting and injuring the enemy, can still fire, but its effective range is no longer there and its power is greatly reduced.

But the Jiannu obviously did not know the exact data of the rockets and the Ming Dynasty's heavy bombs. Xiong Tingbi was not in a hurry. When the Jiannu came to attack, he would cover the entire area with firepower from muskets to artillery, from a hundred meters to two miles.

Nurhaci ordered the horn to be blown, but he did not rush to attack. This was to let the defenders in the city know that reinforcements were outside the city, so as to stabilize the morale of the army and make them fight to defend the city.

Moreover, the Jiannu army had made sufficient preparations for this mobilization, bringing with them a large number of shield carts and dozens of trench bridges.

In the cold wind, the Jiannu army lined up and waited. In front of the formation were countless shield carts pushed by baoyi. They were just cheap cannon fodder.

Not attacking? Xiong Tingbi put down the telescope and squinted his eyes.

He could probably guess what the old slave was thinking. He wanted to wait and let the Ming army suffer losses in the siege and their morale be frustrated.

In my opinion, Haicheng is very strong and cannot be breached in a short time.

Since that’s the case—Xiong Tingbi curled his lips and sneered, then let you watch the city fall with your own eyes, and watch the heads of the Jiannu soldiers defending the city being hung on high poles!

"Stop the shelling," Xiong Tingbi ordered, "Order the engineers to load gunpowder and start blasting."

During this period, the Ming army not only dug trenches and built camps, but also dug two tunnels leading to the city from the south. In order to prevent the gunpowder from becoming ineffective due to moisture, the gunpowder was not loaded in advance.

But this final process doesn't take long, two hours is enough.

Since Nurhaci was not fooled by the feint, he immediately launched an attack. Xiong Tingbi did not need to make another feint and waste ammunition, and directly broke through the city, letting the Jiannu watch helplessly.

The engineering corps, having received the order, immediately took action, transporting boxes of gunpowder packed in iron boxes into the tunnels and loading them under the city foundations...
