Cold ice can't break the water, and dead wood can meet spring again.

Li Huayi's gaze was not Su Qinyu herself, but indeed the 'Tianyouqin' in front of her. It turned out that what he had been looking at was the 'Tianyouqin', but before he clearly said that this qin was not a heirloom blade, but why did he always care so much, what was the reason for this?

Li Huayi used the 'Heavenly Dragon Lance' to block Gan Ning's attack, but the Afterimage Sword changed too much, and it could often change more than a dozen identical blades, saying that it was just a phantom, but it made people unable to distinguish, I looked at the Afterimage Gun in Gan Ning's hand, in fact, the principle of the Afterimage Gun is not profound, when the speed of the human eye to see the object is not as fast as the movement speed of the object itself, there will be [Note 1] afterimage. The faster the object moves, the more noticeable the afterimage becomes. In other words, the best way to stop the Remnant Gun is to be still, but it is not easy to get Gan Ning to stand still with the gun.

Gan Ning did not have the slightest intention of slowing down the attack, rushing left and right, Li Huayi gradually began to be tired of dodging, there was no possibility of counterattack, in this way, Li Huayi was very dangerous, Gan Ning was more and more courageous, the afterimage gun was unpredictable in his hands, and suddenly the 'Tianlong Gun' in Li Huayi's hand was picked off by Gan Ning, and he could only dodge with his bare hands.

Seeing this, I immediately threw the 'Tiange Sword' that Mo Qifeng had dropped aside, the 'Tiange Sword' was originally a three-foot short sword, and it was too much to deal with Gan Ning's afterimage gun.

I walked up to Su Qinyu's side and asked, "If what Li Huayi said is true, then where is the fourth heirloom blade of your master's sect now?"

But Su Qinyu's eyes have always been on Li Huayi's body, and he didn't pay attention to me at all.

"Do you know that if you can't think of any more ways to control the enemy, I'm afraid Li Huayi won't be able to resist for long." I looked at him anxiously.

As he spoke, Gan Ning took advantage of the situation and almost hit Li Huayi's face, but fortunately, he reacted in time and blocked the afterimage gun with the hilt of his sword to block the attack.

"Do you see it! What are you waiting for? If your blades can handle the Remnant Gun, maybe we can all get out of here, or none of us will be able to leave. I yelled at Su Qinyu.

She seemed to finally realize what I said, but she still didn't speak, just looked at the 'Tianyouqin' in front of her. His expression was sad and he burst into tears.

She pushed the 'Tianyouqin' in front of me and said slowly, "The answers you want to know are here, you can find them yourself." ”

Sure enough, as I thought, all the answers are in this 'Heavenly Shadow Piano', as long as I open this piano, maybe there is everything I want to know. But now a new problem has arisen, how to open this piano, I have been looking at it for a long time, and there is no place on the piano that can be opened. I'm afraid that if you want to open this qin, you can only destroy it, but the combined force of the blades in the hands of Mo Qifeng and Fang Shuran before can't break this qin, and I'm afraid it's even more impossible to do it with the 'Sun and Moon Double Chopping Knife' in my hand." But I still want to give it a try, I waved the double chopping knife in my hand to signal Su Qinyu, she didn't care, I slashed hard towards the side board of the 'Tianyouqin'. But the piano didn't move at all, there was no damage at all, this is really strange, why can't the sword penetrate the ordinary qin?

"If you want to open this qin, it is impossible with the blade in your hand, although this qin seems ordinary, but in fact it is invulnerable, if you want to open this qin, I am afraid it is difficult." Su Qinyu said disdainfully.

Su Qinyu is right, this piano seems simple, but there is another mystery, but if I don't hurry up and find a way to open this piano, Li Huayi will be very dangerous, I have to come up with a way as soon as possible.

I looked at this qin and pondered, and now all the keys are gathered on this 'celestial lyre'. All the hope of going out of the city is here, but what if even if I think of a way to open this piano, I still can't stop Gan Ning's afterimage gun? But now I really don't have the heart to think about other issues, and the top priority now is to think of a way to open this 'Heavenly Shadow Qin' first.

Watching the battle between Gan Ning and Li Huayi become more and more intense, my thoughts are getting faster and faster.

【Note 1】Chinese name: afterimage, foreign name: Persistencn of vision, visual staying phenomenon, duration of vision, alias: visual persistence phenomenon.

When the eye captures the moving thing at a speed that is not as fast as the moving thing itself, the eye cannot see the position of the object in motion, but under the influence of visual transience, the eye can see the image of the previous position of the object, and this kind of image is called an afterimage.

The phenomenon of Persistencn of vision is a phenomenon in which the vision produced by light on the retina remains for a period of time after the light has stopped.

When the object is moving rapidly, when the image seen by the human eye disappears, the human eye can still continue to retain the image of its image for about 0.1-0.4 seconds, this phenomenon is called the afterimage phenomenon, which is a limitation of the human eye, when the human eye looks at the object, the image is on the retina, and the optic nerve enters the brain, and the image of the object is felt, but when the object moves, the influence of the optic nerve on the object will not disappear instantly, but will continue for 0.1-0.4 seconds, this property of the human eye is called 'the afterimage of the eye'.

Jingzhou, it is generally believed that during the Eastern Han Dynasty, Jingzhou originally had seven counties: Nanyang County, Nan County, Jiangxia County, Lingling County, Guiyang County, Wuling County, Changsha County, after the Battle of Chibi, the seven counties of Jingzhou were divided by Liu Bei, Cao Cao, and Sun Quan, Cao Cao occupied the largest Nanyang County in the north of Jingzhou, Sun Quan got Jiangxia County and Nan County, and Liu Bei got four counties in the south of Jingzhou (Changsha, Lingling, Guiyang, and Wuling). Liu Bei's military security was not conducive to development, so he proposed to Sun Quan twice to borrow the southern county of Jingzhou, and Eastern Wu Lusu persuaded Sun Quan to temporarily lend the southern county to Liu Bei, so Liu Bei had five counties of Jingzhou (Nanjun, Changsha, Lingling, Guiyang, and Wuling).
