Su Yang did not tell Xue Nu and the others about his worries.
Although Lv Donglin is still in a coma, Xue Nu and the others are incredibly loyal to Beigong War God. They were able to stay with Su Yang because they believed Beigong War God wouldn't be in danger; they were only here to take care of Lv Donglin.
If they were to find out Beigong War God might be in danger, they would definitely be unsettled. They might leave Lv Donglin here to go back and help Beigong War God, which would only make things more troublesome and chaotic.
Su Yang walked out of the World Melting Furnace alone and, holding Beigong War God's contact details obtained from Xue Nu, immediately made a call to the War God.
Although Su Yang had been in the World Melting Furnace for some time, in reality, less than an hour had passed outside. At this moment, Beigong War God had yet to leave the Capital City's area.
