Champa did send troops when Jiaozhi (Vietnam) entered Song territory.

When news of Jiaozhi's crushing defeat reached his country, Jaya Indravarman heard that the Song army was extremely powerful, having defeated Jiaozhi's 100,000-strong army with only 8,000 men.

He worried day and night whether the Song emperor would send someone to question him, and he was also preparing to send someone to the Song dynasty to plead guilty.

I didn't expect the Song Dynasty's envoy to arrive so quickly.

The translator on one side translates the dialogue between the two.

Zhang Jun said, "Your Majesty, to be honest, I came here concealing my identity for my own safety."

"Your Excellency is overthinking this. Our country respects the Great Song as its suzerain state. Your Excellency's arrival is a great honor for our country. How could we dare to harm Your Excellency?"

"If that's the case, why does Your Majesty aid and abet the tyrant?"

Jaya Indravarman asked in a trembling voice, "This humble king does not know what the envoy has to say?"

"The rebels of Jiaozhi are cruel and tyrannical. Not only does Your Majesty not send troops to uphold justice, but you also send more troops to help Jiaozhi harass the southwest of the Great Song!"

At this point, Zhang Jun's tone became stern.

At this time, the Song Dynasty had just won a great victory, so Zhang Jun naturally had enough confidence to come and question them.

Jaya Indravarman stood up abruptly, his face pale: "Your Majesty, please calm your anger. This matter was also out of our country's control. Jiaozhi is cruel and forced our country to send troops. If we did not comply, they would destroy our country. I, the king, am concerned for the people and cannot bear to see them suffer. Therefore, I had no choice but to agree to Jiaozhi's request."

"Upon learning that His Majesty favored Jiaozhi, the Holy Emperor was furious and intended to send a navy of 100,000 to conquer Champa!"

Even though he knew Zhang Jun was deliberately deceiving him, King Jayaindravarman of Champa was still very afraid.

"Your Majesty, please forgive me! I, your humble servant, am willing to serve you with utmost loyalty!"

Zhang Jun then said, "I have heard that the southern kingdoms have suffered under Jiaozhi for a long time. The Holy Emperor has a heart that cannot bear it and intends to punish the traitors of Jiaozhi, uphold the Holy Way, and restore a bright and clear world to the southern kingdoms. Is Your Majesty willing to send troops to punish the rebels?"

"I, Wang, am willing to be shattered to pieces for the Holy Emperor!"
