Karna came to know from his non-human spies about everything that was happening on Hastinapur. But he knew that this was necessary as Duryodhana should be punished and felt pain for doing all the sins. But still, he felt bad. But in the Agyatvas a new problem arose. Dusshasshan was a good friend of Keechak and when they search everywhere and did not find the Pandavas, Shakuni suggested trying Matsya and they sent him the news to search for the Pandavas. Keechak was happy as he loved to torment the helpless.Keechak also asked for their help in killing Virat king and Prince Uttar. So e asked them to attack Matsya and kill the king and prince and make him the King in exchange for his help to find the Pandavas.

One day he was strolling in the garden and saw Draupadi. Though she was in a veil but Keechak was curious to see her face and wanted to go near her. But Queen Sudeshna was a strict person who never tolerated anyone misbehaved with her maids. She like her husband did not like her brother but she was also helpless. Keechak when got a positive signal from Shakuni and Dusshasshan became more arrogant and he openly tried to misbehave with Draupadi once. But Brihannalla aka Arjun sensing the problem reached there on time. He very cunningly brought princess Uttara there as well and seeing her Mamashri misbehaving with Sairindhri, Uttra was disgusted, 'Mamashri, don't you have any shame? She is a married woman and you are misbehaving with her. Please go away or I will complain to father.' Keechak left but in his mind, he plotted revenge. 

Draupadi ran to meet Avni. To others, it might look like she went to the doctor for treatment but actually, she asked her help to teach Keechak a lesson. Avni secretly met Karna and asked, 'Hey Vrisha (Karna's new name) the royal palace has so many mice. Especially a big rat is creating havoc. I need to make a potion to get rid of the rat. Can you bring me some herbs?'

Karna understood the code words, 'Sure Vaidji, tomorrow is my day off. I will go to the nearby village to collect the herbs. Around the banyan tree inside the forest has many herbs. But why do you need potions? Just beat it to death.'

Avni, 'It's big and fast. Very difficult to beat. If we can surround it from eight sides, then maybe we can kill it.'

Karn understood that she was trying to say that Keechak was creating havoc but it was difficult to beat him individually. So they needed to do something together. And 'herbs' means she wanted to meet everyone in the forest.

When they were talking, Nakul was also present as they were standing near the stable. To others, it seemed like the Vaid was ordering the Charioteer to bring herbs. But  Nakul also understood the code and he secretly informed Sahadev. While Avni informed Draupadi, Arjun and others.

At night, in a forest outskirts of the Matsya capital city, eight figures covered in dark clothes were gathered in a cave under a banyan tree. 

Yudhistir, 'Is everyone here?'

Draupadi, 'Yes'

Avni, 'Thank God! We came separately so that no one can notice our departure.'

Karna, 'Yes I was scared for Arjun. Her beauty can attract anyone. Thank god no one noticed her.'

Everyone laughed and Arjun pouted, 'Jyasht, you too?'

Nakul, 'Thanks to Devi Urvashi that she changed Jyasht's appearance. Otherwise, we have to save him from the women of this kingdom.'

Bheem, 'If anyone tries to cast an evil eye on our Jyasht, then we have to protect those women from our Bhabishri.'

Yudhistir, 'Enough now. Stop teasing them. Bhabishri, why did you call us?'

Avni and Draupadi narrated the entire incident. Then said, 'Keechak is Dusshasshan's friend. If we do anything then it will attract unnecessary attention.'

Draupadi, 'But Jiji if we did not do anything then he will be encouraged to do something really bad.'

Karna, 'So there is only one way. WE can wait and avoid him and if he tries to do anything bad, then we have to kill him in such a way that no one can suspect it as Pandavas work.'

Later in Matsy palace

Keechak was getting out of control. In his lust and arrogance, he terrorized the entire Matsya as he knew that within few days Dusshasshan would attack Matsya and he would be the next king. One day he was practicing in the arena and Draupadi was passing from there. Suddenly a gust a wind moved her veil for a few seconds and due to Keechak's sheer luck, he saw her face just for a while. But that few seconds were more than sufficient enough to drive him crazy.

Keechak, 'Such a beauty, she is made to be my queen. I have to get her in my bed. But who is she? Such a beauty can never be a maid. Is she really Draupadi....Hmm, the description provided by Mitra Dusshasshan matches with her. Now I can fulfill my dream.'

So next day he approached Draupadi, 'Look Sairandhri, I know who you are. You are Draupadi.'

Draupadi was scared. But she maintained calm. Then Keechak said, 'Look Sundari, I won't harm you if you do whatever I want. I want you to come to my room at night. If you can satisfy me then I will not tell Dusshasshan about you. I know your husbands are also here somewhere. So don't try to inform them. I will keep an eye on you from now on. If you don't obey me, I will imprison you all and give you to my mitra in a silver platter.'

Draupadi knew she had to act in front of Keechak to save her husband and others. So she pretended as if she was scared and meekly said, 'No no Senapati Mohodaya, please don't do this. I will come to you at night.'

Draupadi knew if she talked to any man then Keechak will be suspicious. So she went to princess Uttra's chamber and said in front of Brihannala, 'The rat is creating trouble again and tonight I think we need to do something. Otherwise, it will bite us  all.'

Brihannala understood her words. Arjun hurriedly informed that to everyone and now all the Kaunteya and their wives were enraged. 

Avni thought, 'I just cut Jayadrath's hand as he was Dusshala's husband. But my will cut this Keechak's m*****d so that he will never do anything to a girl.'

Karna asked Yudhistir to keep the King and courtiers busy in the sabha, while Arjun and Draupadi were taking care of the princess and the queen. Nakul and Sahadev forced the horses and cows to make noise so that no one could hear Keechak's scream. While Avni, Karn and Bheem reached Kechak's room. Avni wore Draupadi's dress and sat on the bed.

Here Keechak was dreaming, 'Today I will acquire one of the most beautiful women of  Aryavart. But if Draupadi is here that means the Pandavas and their elder brother and his wife are also here. Then where are they? I did not see any other girls as beautiful as Draupadi as Dusshashan described. And Karna, he has a unique radiance but I don't see anyone matches up with the appearance. But okay, that fool Draupadi believed in my words that I am going to spare her family. Once I have her, I will blackmail the Pandavas to come out and then I will imprison them and handover them to Dusshasshan.Ha...Ha what a plan, you are very intelligent Keechak.' Little did he know that soon his dream was going to shatter.

Keechak drank lots of wine and took his leave from the sava early. He went straight to his chamber and saw Draupadi was waiting for him in bed. He was overjoyed and removed her veil and was shocked to see Avni who was still in her male Avatar.

Keechak, 'You are the royal doctor, what the hell are you doing here.'

Avni responded with a tight slap. Keechak fell from the bed and then Karna and Bheem came out. Bheem started beating him badly and when he was almost going to tear him apart, Karna stopped him.

Karna, 'No Bheem, if you do that then people will be suspicious as everyone is familiar with your strength. I think we should kill him here and move his body so no one can have a clue.'

Avni, 'And King Virat himself wanted him gone. So we will send him a letter saying that Keechak was removed from his path. Now he can give any excuse to the courtiers.'

Saying that all three of them started beating him badly. As promised Ani cut his m*****d and then Karna also cut his body into pieces. He then wrapped them into a bag and stealthily took it out from the palace as Keechak already ordered the guards and servants to vacate the place so that he could enjoy his night properly. Before taking his body out Karna searched the entire room to remove any clues against them. There he found a letter from Dusshasshan that soon Hastianpur was going to attack Virat. Karna kept that letter and used the mantra and he and Avni went to the forest and bury the body in the earth using Avni's power to create a hole in the earth and then again cover it. They also sent a secret letter to king Virat saying that how Keechak planned the attack with Dusshasshan and now he was dead. Now the king was out of danger but he asked to be prepared for the upcoming war.   

Next day,

King Virat was having a headache of a lifetime. First, a letter proving Keechak's betrayal and then someone killed him and hid his body. He knew that he should be grateful to that unknown person but he was still skeptical about that person's motive. Another problem was what would he tell to his courtiers. After many thoughts, he decided to tell the partial truth.

King Virat in his court, 'Courtiers, our commander in chief Keechak was planning an attack to our country. He joined hands with Hastinapur. But I came to know about his planning and before I punished him, he flew from here. But we have to be ready for the upcoming war. Shrutsen, you are going to be the next army commander. Prepare the army and increase the border patrol. Mantriji, take care of the supplies and store enough foods. Durdant..raise the security of the royal women. Now everybody starts the preparation.'

The Pandavas were relieved that King Virat took their warning seriously but now the problem was the war. Matsya could not fight with the entire army of Hastinapur. The Pandavas needed to intervene but it would disclose their identity. So now they had a really big problem ahead.
