I attacked him first with my swords.
I stage this duel because I already knew about his fighting style.
Zatril fighting style was the complete opposite of Guram style.
His used a sword style that focus on defense and counter attack, but he didn't know yet that his fighting style will be his main reason for his downfall.
With the ability of the dreadnought armor, I have 30% chance to invoke the dread slash skill for every 5 consecutive attack that hit him.
It doesn't matter whether the attack was blocked by him, the only thing matter was that I hit him and did that 5 times in a row without stop.
So that's what I did after the duel start, I started to attack him continuously without stopping while Zatril blocked all of my attacks.
When I hit him for the 25th times, the skill got triggered and made my attack ignored 50% of his defense while in the same time enhancing my attack damage to 200%.
Zatril was still getting used to my fighting pattern and got very shocked when he felt that my attack managed to damaged him a lot even though he blocked my attack.
He staggered backwards and cough some black blood out from his mouth and it created a chance for me to start another attack so start to attacked him once more.
I didn't gave him any time to think and analyze my skill and forced him to block my attack again.
And then I repeat to attack him again.
because Zatril got injured internally, he didn't have any strength to make a counter attack.
He can only hopelessly blocked my attacks that never end.
And not long after that, the skill got triggered again and made Zatril dropped to his knees while coughing out a lot of black blood from his mouth.
"Yo-you lied to me!"(Zatril)
he said grudgingly with his hoarse voice while clutching his chest with his right hand.
"I never lied to you, you are the one who made all those assumption and believe it yourself. Now try to remember, did I ever confirmed what you have said to me?"(Vestia)
"*Cough!* Des-picable...!"(Zatril)
And that was his last word before he fainted.
Since he lose the duel, his guardians also didn't made any struggle to follow us back to our camp as prisoners.
We chained all of the monster with A-rank above with the sealing chains and took them back with us to the camp.
As for the B-rank and bellow monsters, they didn't even dare to attack us and follow us on their own accord as they also know about the duel content and knowing that their own lord had lost, they already surrendered to their fate.
I also made sure to leave some of my subordinates to guard Zatril dungeon heart and make a line between my camp and both of Zatril and guram dungeon so that when the time to destroy their dungeon heart come, I will only need to realy the message using the monster line.
After we had reached our camp, Rowan told me that since he was the fastest among the ten guardians, he will relay our victory to Valakh himself.
As for the rest of us, I made my troops rest for a bit first before starting our march once again and this time our mission is to attack the enemy from behind.
But before that, I made sure that all of the captives here are already chained to the point they cannot move and for another line of safety, I also poisoned them with paralyze poison.
I also decided to brought one guardian of each captured demon lord with me.
It was then that I heard the system sound again in my head.

I look at the new mission and rewards and found that the minimum rewards is a D-rank summon pool again.
I already got 4 summon pool from the first and second main quest.
Those were the B-rank Blood Earl Summon Pool , C-rank Blood Viscount Summon Pool , C-rank Universal Summon Pool, and D-rank Giant Blood Bat Summon Pool.
Just this gains was already more than what I had expected at the beginning.
The inheritance trial really a trove of treasures but only to those who can clear the trials.
I also got many experience with how to lead my troops in a war and how to fight against fellow demon lords.
I let my troops to rest for 15 minutes first before we continue our march toward the enemy fourth camp.
The [Orc] demon lord Ogar, and the [Water] demon lord, Zafina.
They are the remaining enemy demon lords that haven't been defeated yet.
The information that I got from Garock said that Ogar is a warrior type demon lord while Zefina is a mage type demon lord.
Their plan was actually to make the mixed troops that will be led by Ogar to attack Valakh in surprise while actually it was a front for Zefina to cast her wide area scale that can wipe out monsters bellow C-rank.
The enemy fourth camp was adjacent with Ogar dungeon so for Zefina to come at the fourth camp that means she left her dungeon unguarded.
Their plan was after Zefina finished casting her spell and wipe out all of Valakh monsters bellow the C-rank, they will start their attack together.
They were expecting Valakh to relocate most of his troops from the other camp to the fourth camp as reinforcements.
After the other camps defense dropped, using that opportunity, Zatril and Guram will join together and attack the second camp to breached Valakh dungeon.
The downside of this plan was that Zefina needed a lot of time to cast this spell of her without any interference at all or the spell will fail.
For Zefina safety, she brought 10 of her guardians here to protect her.
The time to cast the spell was 10 hours, and now I roughly still have 4 hours before she finish casting her spell.
Unfortunately, they are still in the dark about their friends defeat and were actually the one fallen on a trap now.
It didn't take that much time for my troops to reach the enemy fourth camp.
The camp was mostly empty since all of the troops there were brought with Ogar to fight Valakh and I guess only Zefina and her guardians remained here.
Since that was the case, I stopped my troops and only brought all the A-rank and S-rank monsters with me to ambush them.
We went inside the camp and immediately noticed the magic in the air were focused on one place and that place must be where Zefina is right now.
We head there silently so they won't get alerted and have time to call back their army.
Not long after that, I found Zefina, stood in the middle of a large glowing magic circle while being guarded by her guardians on every side of hers.
I then divided my team into 10 groups and each group will responsible to handle one of Zefina guardians while I will confront Zefina herself.
After counting on three, I gave the signal to all my subordinates to start their attack.
I also ran toward Zefina who was currently have a shocked expression planted on her face.
Zefina guardians was caught off guard and most of them got injured from the sneak attack, while for me, I unexpectedly took down Zefina with my first attack.
It seems she got some kind of backlash after having her spell interrupted which injured her internally and that caused her can't dodge my attack.
With Zefina down, all of her guardians also followed to surrender.
I didn't expected for it to end this fast and was dumbfounded myself, but I can't keep wasting any more times as there is still one big battle left to come.
I chained Zefina and her guardians with the sealing chains and left some of the A-rank monsters to guard them there.
I don't have time to bring them back to my camp first so I can only leave them there and took them back after the battle is over.
With Zefina down, there is only Ogar left, so I took all of my troops that amount more than 300.000 monsters and led them to attack Ogar from behind.
Of course with so many monsters moving fast like that, it will make a lot of noise and also got detected by the enemy at the front.
But I didn't care whether they found out or not as right now it was already to late and Ogar troops were sandwiched between my troops and Valakh troops.
They didn't expected to be attacked from behind, because of that they didn't have enough time to counter my troops attack.
With my troops here, blocking their path, they won't be able to retreat.
I also shouted to them that except for Ogar, all the other demon lords has already been captured to make them surrender.
Even if some of them won't believe my words, at least it will wither some of their morals and spirit.
Seeing that they still fighting back, I called Aridnia to come beside me and join me with attacking them.
Since I have broke Aridnia, she didn't hesitate and complied to my order.
Even though none of Garock troops were here, some of the other enemy troops that has seen her before were able to recognize her identity as one of Garock guardians.
After that, I also show the other captured guardians to the enemy troops and their appearance made them stop fighting.
The guardians appearance made all the monsters except Ogar troops believed my previous words and choose to surrender.
As for Ogar, he couldn't believed the fact that all of the demon lords beside him has been captured and defeated.
He gawked when he recognized all of the captured guardians bellow me and even more so when he noticed that Aridnia which was one of Garock guardian also joined the attack.
Aridnia presents here made him think about Garock betrayal and their downfall and made him paled.
Valakh then shouted toward Ogar to surrender and he also promised to not kill him if he do so.
With almost all of his allied army surrendered, he got no choice but to admit his defeat as well.
At least there were still a chance for him to live if as Valakh vassal if he surrendered.
As long as he can still stay alive and not killed, then he would gladly choose to survive.
With that, the war is over and my side has obtained victory.
