Although Qian Yan didn't know all the details of the ditch, she still had a rough idea that there was a main ditch under each of the four main streets, and that there was a horizontal branch connecting the main ditches in every three or four rows of streets. If you draw it on paper, it looks roughly like a spider web, becoming increasingly sparse from the inside out.
She was now sitting above a branching ditch.
No one noticed that a lot of frost had formed underneath these deep ditches.
The task Xia Fan assigned to her and Qianzhi was to turn the outer drainage channel into a huge "water storage tank." All the undischarged water was directed into the horizontal canal to the west of the palace, causing the water level here to exceed the main canal under Baihu Avenue.
Through the water holes under her feet, she could see that the still water was almost overflowing the ground. This scene that only appeared during heavy rains was obviously not the norm, but few people would notice this abnormality.
After all, even if the water overflows, it will only cause some inconvenience to the celebrating people. When the ditch is unblocked, the water will naturally disperse. Who will treat it as a big deal
In fact, even Qian Yan didn't think it was a big deal.
According to Xia Fan, the "celebration gift" he gave could concentrate all Shangyuan City's defense forces on the West Block, but it was hard for her to imagine what could be done with all the rainwater and sewage.
By the way... He seemed to have said it would explode
"Look, the palace door is open!"
"Is that the worship group that set off first?"
"Will His Highness the Crown Prince show up?"
"Fool, he is already the emperor now!"
The crowd suddenly burst into cheers.
For the people, the things that were done in the palace such as the officials urging people to enter, issuing edicts, etc. had nothing to do with them. What they could see was that King Xinqi started from Baihu Avenue and went all the way to Lingshan Ancestral Temple to worship. This process will last for most of the day, and there will be performances, music, fireworks, and firecrackers, making it very lively. Therefore, when the west gate of the palace wall was opened, the voices of the onlookers immediately reached a new high.
This is also the time for planned action.
Qian Yan took out a ball of gunwool soaked in grease from his arms, carefully lit it, and stuffed it into the hole under his feet.
The moment the collodion was about to enter the water, an ice crystal boat quietly formed and held it up just right.
After completing the preparations, Qianyan stood up, passed through the crowds, squeezed to the side of Baihu Avenue, and stamped his feet at the intersection of the canals.
A newly raised piece of solid ice suddenly pushed open the ice-blocked crossing.
The accumulated sewage immediately resumed flowing, but this time, its flow direction was from outside to inside, and poured back into the main canal.
On normal days, people standing on the street could even hear the rushing sound.
But at this moment, the hustle and bustle of the city completely covered up the sound of the water.
With the help of the water force, the ice boat also moved. It dragged the guncotton through the ditch and soon drove under the White Tiger Avenue.
At this point, Qian Yan's mission has been completed.
According to the plan, she should immediately leave the main street, head towards the west gate, and take advantage of the chaos to evacuate Shangyuan City.
However, the living dead did not move.
Because she was also curious about what Xia Fan had done after he had been busy here for nearly two hours.
In a place where Qian Yan could not see, the speed of the ice ship had slowed down significantly - the size of the main channel was much wider than the branch channels, and the amount of water accumulated before could not fill the main channel, so after the water flows merged, the water surface quickly A new balance will be formed.
Under the scorching flames, the ice ship itself began to melt, and the water droplets flowing out had accumulated at the bottom into a puddle the size of half a palm. It's just that the grease will not melt when it comes into contact with water. The oil film they form allows the guncotton to continue burning on the water.
That weak light also slightly illuminated this land that never saw light.
If someone could sneak into it, they would find anomalies in the main channel.
It was originally supposed to be a paradise for mice and insects, and with the addition of fish fry or floating-leaf plants drifting in from the landscape garden, this place can be regarded as a unique biosphere.
But now the channel is completely lifeless.
Animal carcasses can be seen everywhere. Whether they are rats, fish, poisonous insects or snakes, they are all floating motionless on the water, as if they have all died. Many animals were even burnt black and smelly, with steam rising from their bodies.
In other words, the temperature here is already very alarming. Even in the daytime, bursts of white gas come out of the weep hole next to the main road, just like a steaming spring in the mountains.
When the ice ship rounded a corner again, the brightness of the flames instantly increased.
Its outline continued to expand, and soon it surpassed the ice ship itself, so that it seemed to take off. Once such a change begins, it cannot be stopped. In almost the blink of an eye, the flames had expanded into a fireball and changed from a dull red-yellow color to a dazzling blue-white color.
The next moment, the manic flames had spread to most of the main canal, and the air above the water seemed to be ignited at the same time, heating the already warm space to hundreds of degrees in an instant! This high temperature caused the water to evaporate rapidly, and the small weep hole could no longer meet its release needs.
Then Qianyan heard a loud noise!
I saw the ground of Baihu Avenue suddenly swelled, and the solid stone pavement suddenly looked like it was made of soft mud. Such a huge deformation directly caused the ground to break and crack. Then white air waves spurted out from the ground, blowing the bricks. Shi rushed directly into the sky dozens of meters high!
And the explosion is far from over.
Like a series of firecrackers, it gradually exploded towards the palace. The roars one after another made the earth tremble. The white smoke that erupted successively formed a towering "smoke wall" on Baihu Avenue!
Qian Yan was stunned.
In her mind, only gunpowder could produce such earth-shattering effects. The problem is that sulfur and saltpeter are strictly controlled medicinal materials, and she has never seen Xia Fan hoard these things. Having said that, even if he suddenly conjured up dozens of large bags of gunpowder, there was no way he could stuff them into an underground ditch in full view of everyone!
This sudden drastic change made the people present panic. They retreated in panic and poured into the surrounding streets from both sides of Baihu Avenue. If it weren't for the series of explosions heading towards the palace, their escape would have been even more chaotic.
The most intense reaction was undoubtedly the worship team that had already walked out of the palace wall. The gorgeous palace maids were so frightened that they dropped their brocades and flower baskets, screamed and ran towards the palace with their heads in their hands. The guards who were clearing the way in front were no better. Many even dropped their flags and fled towards both sides of the White Tiger Avenue, fearing that an explosion would happen at their feet the next moment.
This "thunder on dry land" is not only a gift to the coronation ceremony, but also a signal for the curtain to rise.
Hearing the roar, Qianzhi lowered the same ice ship closer to the palace.
