A large wooden warship takes at least three to four years to build, from gathering the materials to completion.
However, the three warships of Suo Lun, from the beginning of their construction to now, had taken no more than a year at most, because the materials required for these warships were purchased from other shipyards regardless of cost by Suo Lun.
Even two of the ships had already been half-built before being converted into two-tiered warships.
"How much longer until these three ships can be launched?" Suo Lun asked.
"Seven days!" replied the commander of the shipyard guard, who was also one of the trusted Samurai of the Suo family.
Without counting the cannons, these three ships alone cost Suo Lun nearly 100,000 Gold Coins, and if you add the cannons, and the cost of training for the cannons, that was beyond calculation.
Of course, there was also the construction of this secret shipyard, plus the salaries of thousands of workers and so on, totally astronomical figures.
