Lan Waihu was a bit scared.
Gu Xijiu looked at her and said, "We might die if we don't put up a good fight against them. Therefore we must give our best effort! The brave can always win. You just need to listen to my command later!"
Qian Lingyu was not afraid, "Don't have to be scared! The worst thing is only death. Xijiu said before; we have to live and die with pride! After 20 years, we will be reborn and be a good person again. We just need to do our best now!"
Lan Waihu took a deep breath, "Alright! Lets do our best!"
Most of the audiences had arrived by now, and it was almost time for the match. Yan Chen stood up to explain the rules, but there were some significant changes. Both parties could use any skills and tricks except for poisons and venom.
After he finished reading the rules, he waved, "You can start now!"
Six of them were standing still. When Gu Xijiu wanted to start an attack, Le Qingxing asked, "Gu Xijiu, why did you stare at us just now?"
Gu Xijiu never expected that the twins would start their battle with this question. She looked at them and answered, "I was trying to see if you guys are monozygotic twins or fraternal twins."
The twins remained silent. The crowd did not understand Gu Xijiu's reply, but Long Siye choked on his tea. He could not help but look at Gu Xijiu and shake his head. However, he was secretly laughing too.
Gu Xijiu was out of her mind when she replied, and just realized that she had used a modern word that was not in their vocabulary. She laughed too and tried to change her sentence, "I heard that twins always act the same so I could not help to see if that was the case. I have no other intention, please dont mind it."
"What are monozygotic twins and fraternal twins?" Le Qingxing insisted on asking.
Gu Xijiu knew that they did not understand so she just casually answered, "It is your level of understanding. If the level of understanding is high, then you are monozygotic twins. Otherwise, you are the fraternal twins"
Everyone thought that it was the right explanation and were relieved, but Long Siye choked another time. He looked at Gu Xijiu and shook his head. Gu Xijiu stared at him to warn him not to reveal the secret.
Long Siye smiled at her and talked to her through Directed Audio, "Liar! You can try to lie some more. I guess your biology teacher will come out from the coffin to scold you!"
Gu Xijiu laughed and replied, "Its okay. Even if my biology teacher could come out from his coffin, he cant pass through time and come to this world."
"It is hard to tell. Perhaps your teacher could do it as he is too angry with your statement."
"Well, he is too weak to fight against me as long as you dont help him."
"To be honest, I felt like punching you too when you explained to the twins in this way. I was your instructor too, remember?"
"Well, do you think they are monozygotic or dizygotic?"
"Of course they are monozygotic. The twins are very alike. Obviously, they came from the same egg and sperm"
"I remember that if twins came from the same egg and sperm, they should be of the same sex but they are not."
"It is relatively rare but still possible. You can observe the twins. There is a mark on the left ear of the brother while the mark is on the right ear of the sister. Besides, you can see that the shapes of their palms are the same. The left arm of the brother is stronger, so apparently, he uses his left hand in combat. The opposite was true for the sister." Long Siye was indeed a physician and was very familiar with all these types of things. He could analyze someone based on the posture of that person.
