In the ongoing war between the two countries, it was conceivable that the arrival of this group of hostage and envoys would not receive any courtesy. The Third Prince and his party did not even have one decent person to welcome them. Li Feng's instructions to Hongqi Temple were ‘act depending on the situation’. The officer of Hongqi Temple really understood the meaning of the ruler and placed the barbarian hostage in an envoy's post and left them be. On the day of residence, the city's internal defense was renewed. The newly formed Imperial Army surrounded the post station by three layers inside and outside, changing shifts every half an hour and patrolling twelve times a day, regardless of day or night.

Everything seemed unusual in those two days. First came a strange and mysterious hostage of the barbarians, then Chang Geng became seriously ill at an unusual time, contracting a high fever with just a bit of cold wind from sitting on Wangnan tower.

Chang Geng practiced martial arts all year round and was very good at maintaining good health. He was in his twenties, logically, even if the wind was any stronger, it would not be able to affect him. But no one knew what was going on that day, his fever was fierce. When Gu Yun rushed back from the Northern Camp in the middle of the night, Chang Geng had already taken the medicine and went to rest, his cheeks burning red from the fever.

Gu Yun checked his forehead and laid down on one side still in his full clothes. Whether he returned home or not, Chang Geng always occupied only half of the bed, and even with the disturbing nightmares, his sleeping posture was very orderly and he never rolled around.

Afraid that Chang Geng’s fever would burn higher at night, Gu Yun did not dare fall into a deep sleep, he woke up immediately whenever the person on the next pillow moved, when he reached out and checked, he found that Chang Geng's body was as hot as charcoal, and his breathing was also erratic.

Chang Geng being disturbed by nightmares was a normal occurrence. Gu Yun was used to them. Most of the time, Chang Geng himself would calm down as long as he reached out and held him for a little comfort. But this evening, it was probably due to illness, Chang Geng's face suddenly appeared painful. Instinctively, he grasped Gu Yun's wrist and closed his fingers tightly. He involuntarily let out a grunt, unable to wake up no matter how he was called.

Gu Yun had to reach out and take a silver needle from the small medicine bag at the head of the bed. He pressed Chang Geng down and pinched him gently on his wrist.

Chang Geng shivered, then woke up.

Gu Yun's pupils shrank slightly — double pupils.
