Although the black powder in William's hand was less than 1,200 pounds, including 300 pounds of refined granular black powder, and another 900 pounds were deployed by William's craftsmen on the spot.

Thousands of Norman archers led the crowd out, and in Andrew. Dalton's leadership suppressed the defenders of Castel Sant'Angelo.

The dense rain of arrows rained down, and in each wave thousands of arrows were shot down, and in just one minute, the Norman archers had fired tens of thousands of arrows, sweeping away the defenders at the head of the city.

Although more than 800 defenders had survived, they no longer dared to stay above the city, and they all hid in the towers of the fortress, huddled and shivering.

At this time, there were no defenders in sight on the head of the castle of Sant'Angelo, and Andrew, as the commander of the archers, immediately ordered the Norman archers under his command to be divided into two hundred men and a total of five groups to shoot alternately, so as to maintain the continuity of vitality and continue to suppress the city.

William looked up at the sky, and saw that a red sun was about to sink into the sky, and knew that his chances to attack the city today were running out, and he had to break through the Castel Sant'Angelo in one fell swoop.

"Fale, you quickly lead a hundred heavy infantry of the personal guards to come forward with the 'giant thunder', and you must split this city wall!" William turned his head to face Faller. Osborne ordered.

"Yes!" Faller led the way, leading hundreds of Norman hoplites dressed in full-body armor and carrying huge tower shields, and slowly marched through the Sant'Angelo Bridge under the cover of a rain of arrows from the Norman archers.

To the surprise of everyone present, these heavily armed heavy infantry did not carry any siege equipment, not even a ladder, but carried six coffins all the way towards Castel Sant'Angelo.

The coffins they carried were not for the funeral of the defenders of the castle, nor for any ceremony, but to use them to blast open the castle walls.

First of all, we must know that black powder does not explode after ignition, but only deflagration, and if you want to make black powder into a powerful bomb, you must put black powder into a sealed container, and the coffin that William scavenged is the ideal airtight container in his mind.

More than 800 years later, a famous general named Yang Xiuqing during the Taiping Heavenly Kingdom often used gunpowder coffins to conquer many fortified cities garrisoned by the Qing army at that time, so that the Taiping army could sweep from the remote corner of Guizhou to Hunan, Hubei, all the way to Nanjing, and capture Jinling City as the capital.

This method is so effective that during the Anti-Japanese War, the soldiers of the Eighth Route Army often buried a coffin filled with black powder under the little devil's bunker, and they could easily blow up the little devil's bunker with a bang.

The method of bombing the city with black powder coffin has many advantages, one is that it is convenient to obtain materials, whether it is black powder or coffin mounds, it is easy to obtain in the east and west; Second, it is easy to operate, this weapon only requires the operator to dig a big pit under the city, stuff the coffin filled with gunpowder into it, and then light the fire rope fuse to detonate it; The third is that the power is huge, a huge coffin can be filled with at least more than 200 pounds of black powder, think about what kind of effect 200 pounds of black powder explodes in a closed coffin, which is equivalent to the bombardment of a battleship's main gun, which can easily blow up the city wall and let the defenders take a plane to the sky.

The defenders hiding in the castle towers pointed at the hundred heavy infantry who were burrowing with six coffins and shovels under the city walls, and laughed at the gopher gophers, who were digging their own graves, and even the coffins were prepared for themselves.

As the laughter rang out, the morale of the defenders in the castle began to gradually recover, and they all pretended to have the courage to look out.

Although they still did not dare to leave the protection of the tower, bravely facing the rain of arrows, their attempts were considered brave enough in the eyes of their commanders.

The defenders of Castel Sant'Angelo, cowering in turtle shells, did not know that their death was near, and they saw the ridiculous gopher behavior of the Norman hoplites as messengers of death.

Although it was almost dark, Fale and a hundred heavy guards were still in full swing under the city walls, and he didn't even bother to wipe his sweat and bruises with his hands to shovel out the dirt, masonry and stone under the walls of Castel Sant'Angelo.

The hard work paid off, and an hour later, Faller and the others finally dug a large pit under the city wall that was four meters long and four meters wide and three meters deep.

Six coffins filled with black powder were stuffed into a large pit in front of the city wall, and there were no gaps in the tightness.

After pulling the wire and sprinkling the primer, Faller and the others slowly withdrew from the place one after another, and did not stop until they were thirty meters away by the Tiber River.

Faller took the torch from under his hand, and with a sinister smile on his face lit and primer on the ground.

Hiss... Hiss...

In the dim darkness of the night, a little bit of fire was very bright, and I saw it rush towards Castel Sant'Angelo like an arrow from the string, and let out a terrible scream like a viper.

Both the defenders of Castel Sant'Angelo and the Norman army waiting on the other side of the Tiber looked unaware of this, unaware of the earth-shattering scene that was about to take place.

"Norman warriors, we have just prayed to the Almighty and All-Knowing Lord to send down a great thunderbolt to split the Castel Sant'Angelo that stands in our way.

Now that God has answered my prayers, a thunderbolt of heavenly punishment is about to fall on the heads of these shameful betrayals, and no one will be spared.

Gentlemen, please join me in watching this thunder of God's punishment punish betrayal! William rode out of the crowd at the right time, raising his clenched right fist in front of them and shouting loudly.

Airplanes...

The Norman warriors present exchanged heads and began to discuss, and although they did not care about William's words, they still stood on tiptoe and stared forward with wide eyes, curious about the legendary heavenly punishment.

It wasn't long before a dazzling huge ball of light erupted from under the walls of Castel Sant'Angelo on the other side of the Tiber River, followed by a deafening roar.

The dazzling light made everyone barely open their eyes, and a huge roar echoed through the city of Rome, so that the Normans couldn't help but cover their ears with their hands, and the shaking ground almost caused everyone present to fall to the ground in a swaying manner.

"Is this really the legendary Heavenly Punishment Thunder?" Caesar, who was standing in the front row, clearly saw this shocking scene, looking at the thick black smoke of the city wall appeared a gap dozens of meters wide, countless bricks and stones splashed out, Rao is always bold and careful Caesar couldn't help but show a dumbfounded expression.
