Bitter Love.

Tang Zen opened a portal that led the two of them to a forest and then she said, "You have the bottle of that spirit rejuvenation potion. Drink those, we are not heading home before you complete the training." 

Hao Ren was surprised but looking at her stoic expressions he nodded. He obediently took out the bottle of spirit rejuvenation potion and consumed two of them. He sighed and said, "This thing loses its effect as the realm gets higher." 

Tang Zen nodded but did not say anything. At this moment, Hao Ren heard a calm voice in his mind, "Ren, are you there?" 

Hao Ren smiled as he realized that Han Lingshi was contacting him. He replied, "Yes, Love, always. Are you okay?" 

Han Lingshi replied in a calm manner, "I am okay, but I am missing your cooking. How will I survive after you go to the spirit shimmer continent."
