A prosperous city like Jiangling, which was close to a river and stood at a key junction connecting east, west, north, and south, would usually have a specially excavated canal leading into the city. Sometimes, the river itself or one of its tributaries would simply be rerouted through the city.
Of course, Jiangling was not like that. After all, with the current level of productivity, they still lacked the ability to divert the Yangtze River into a city.
Jiangling's water gate was extremely wide, since it had to allow ships traveling north and south to pass through. But precisely because of that, a water gate like this could not use a thousand-catty sluice gate, nor could it be blocked off. It relied on an iron-barred gate instead.
Each iron bar in the gate was as thick as a child's arm. Once lowered, even the large ships that traveled the waterway would be unable to smash through it, let alone a person.
However, too many established rules had been brutally shattered before the great age of the present day. For example, right now.
A large ship could not ram through the water gate because it only had the force of a single impact, and that force was too dispersed. But for the three of Guan Yu...
"Hah!"
With a thunderous shout, Guan Yu combined the Moonlight Three Slashes into a single strike. The originally emerald-green blade aura condensed into a ghastly green mass, almost solid as it slammed heavily into the water gate.
"Boom!"
The deafening impact made even the city wall above the entire water gate tremble. The gate itself gave off a series of cracking sounds. It was only because the water gate had been nurtured and reinforced over a long period, as well as strengthened by cloud energy,
