The reason Ling Zhenfei didn't let Hoshino Yuji take action was that Hoshino Yuji had just finished treatment, and using Northern Spiritual Energy now would cause a lot of trouble.
Thus, the swiftly flying invitation headed toward the two, but Ling Zhenfei immediately condensed a strand of Northern Spiritual Energy that happened to block it in front of Hoshino Yuji.
This strand of Northern Spiritual Energy was given very skillfully. Although very subtle, it just appropriately slowed down the speed of the invitation.
After the speed slowed down, Hoshino Yuji reached out and grabbed the invitation without even looking at it and handed it to Ling Zhenfei beside him.
Ling Zhenfei took the invitation in his hand and said to Hoshino Yuji in his heart, "Tomorrow is absolutely impossible, we won't make it in time. We know our situation well enough, but we don't know what the other side is like."
