Everyone in the consulate knew that this battle was inevitable.

Lu Junxiang led his army to attack Dong's mansion. The musketeers took advantage of the terrain to resist and suppressed the offensive for a time.But Lu Junxiang quickly used poison gas bombs, and the poisonous fog filled the mansion.

He Jianxi found him with the help of Wesley and handed the money to him.Zhang Haiyan deciphered the code on the money and finally confirmed that the entrance to the Southern Archives was at Haili Bank.Even though Zhang Haixia was on the verge of life and death, he still kept a backup plan for him as before.Zhang Haiyan and He Jianxi went to the bank, and the hope of saving people became concrete for the first time.

The money left by Zhang Haixia became a key prop in this episode.It is no longer just a relic entrusted to He Jianxi before his death, but was designed in advance by Zhang Haixia as a code carrier, pointing to the entrance of Haili Bank and the Archives.He Jianxi was able to hand the money to Zhang Haiyan, seemingly by chance, but it actually continued Zhang Haixia's protection of his junior brother.At the Dong Mansion, Dong Shichang's sacrifice deprived Zhang Haiqi of important support and made Lu Junxiang's pursuit even more cruel.The two lines urged each other overtly and covertly: Zhang Haiqi must hold back the warlord, and Zhang Haiyan must find the medicinal materials as soon as possible.At the end of episode 13, Hailey Bank changed from an ordinary location to the entrance of the Southern Archives.
