According to Lin Yi's suggestion, not only should the city walls be constructed with this material, but the ground within the city needs to be hardened with it as well.
Never mind whether we can build a modern city quickly.
The ground hardening project alone is indispensable. Otherwise, if it rains and the whole Capital City turns into a muddy swamp, it will be very inconvenient for the merchants and unsightly as well.
At this time, Lin Yi truly agreed with the saying that wealth comes after roads are built.
The next day, just as dawn broke, all the workers hurried to the city walls to start their new day's work.
This continued for two days straight.
However, their confidence in the cement dwindled.
The reason was that today, when they were building the wall, part of it collapsed.
This made them even less confident in the cement; they were now genuinely fearful. Could this material really hold up?
