The clean-up work after the war was basically completed within two days, which really made Concubine Xiaoya tired enough, looking at the mountains of corpses being burned by the fire, the heart of the castle lord was full of sourness, and it was not until this moment that she suddenly felt that the burden on her shoulders was a little heavy.

She thought of the problem that she could ignore before, that is, she represented more than just one person, there was Oolong Fort behind her, and there were thousands of disciples, as the castle master, any decision, any slight mistake, could lead to the death of countless people under her command. This time, if he had been able to gain insight into Xie Xuechen's intentions and tricks earlier, Oolong Fort would not have suffered such a big loss, and when he thought of this, the heart of the castle lord was full of chagrin.

However, the rebellion of the three envoys of the Oolong is something that no one can imagine.

All that's left is to rebuild the houses that have been destroyed by the fighting.

Tang Feng couldn't help much with these things, except for comforting Concubine Xiaoya's frustrated mood, for several days in a row, he was recuperating his body, after his strength and physical body became stronger, this time the recovery period was also much shorter than before, just three days of effort, Tang Feng had already recovered, although he was not at his peak, but he also had the power to fight.

In addition to recuperating his body, Tang Feng will also go to see Qiu Qianbian and He Xiangning when he is free, the injuries of the two of them are not healed in a day or two, but they are finally in a state of improvement. Qiu Qianbian had already woken up from his coma, and when he recalled the battle with Feng, he was really palpitating.

At that time, he was slapped in the chest by Feng Jingsheng, and he passed out directly, and he didn't know what happened later, and it was only from Tie Tu and Qiu Jueyin's description that "I learned that Feng Jingsheng was dead." Qiu Qianbian almost shocked Tang Feng into a celestial!

Several people privately discussed the reason for Tang Feng's sudden increase in strength, but they still came to the conclusion that they used a secret technique with huge sequelae, because Tang Feng's languishing appearance in the past few days is the best proof.

This is just a private discussion, and everyone holds this matter in their hearts, "I won't ask, let alone tell others." Everyone has something to be busy with, and Tang Feng is no exception, taking advantage of his health to improve, he has been obsessed with studying Xie Xuechen's iron fan in the past few days, and he has already achieved some results.

It is said that it is not made of fine iron, and from the outside, the fan bone has some metal characteristics, but it seems that some other things were added to it during smelting.

On the first day of the iron fan, Tang Feng dismantled the fan, the iron fan is composed of a total of ten fan bones that show a dark red metallic color, and a piece of smooth and even some cool and silky touch of the fan, this fan seems to be a piece of silk brocade with a good texture, it is not an exaggeration to say that it is a good silk, but in fact, "this fan is not a fabric, let alone ordinary silk, because its defense is quite outstanding."

Tang Feng was just curious, and used his black short sword to test the strength and toughness of this fan, and the result was unexpectedly, the black short sword of the Gangbing level "couldn't leave any traces on this fan, even if Tang Feng had three successful powers, it was still intact."

Tang Feng's insight is not short, but he still can't see what kind of material it is made of from the fan that looks like brocade, and can only infer from the fine traces of the fan that it is completely woven by skillful hands.

After asking Uncle Xiao and Uncle Duan, the two of them didn't even know what the material was in this fan, and finally got an answer from Aunt Ye.

"This fan is cool and strange" is finely made, and if my guess is correct, it should be made of ice silk. The Snow Maiden took the fan and looked at it for a moment before she spoke.

"Ice silk?" Tang Feng was puzzled, "Silk can also be so tough?"

Not only tough, but also extremely elastic "Tang Feng If he uses force, he can pull a fan that is only one foot long into about three feet, and it will return to its original shape after letting go."

"It's Ice Silk. The Snow Maiden repeated, The spirit beast unique to the extremely cold land, ordinary ice silk will naturally not be so tough, but if it is an ice silkworm that has survived for hundreds of years, the silk thread spit out is an excellent material, and if it is used to make clothes, it can have a strong defense, but this kind of thing is rare, the ice silkworm that has survived for a hundred years is rare, not to mention that the ice silkworm will not spin silk under normal circumstances, and will only use silk to protect itself when it encounters danger, and the silk thread spit out by an ice silkworm in its life is also very rare, and if you want to weave such a fan, you have to have at least hundreds of ice silkworms。 ”

Tang Feng heard two tricks and lit up: "This thing is very valuable, right?"

"What's more valuable?" the Snow Maiden gave him a disgusted look, "It's a priceless treasure, but whether it's ice silk or not, you have to try it to find out." ”

"How to try?" Tang Feng couldn't wait to know the answer.

The test is very simple, the snow girl directly threw this fan into the burning fire, and the result was that under the stunned gaze of a vote of people, this snow-white fan was not damaged in the slightest, not only that, but the area where the fan was pressed was not there a flame at all, as if the flame also had spirituality, and it dared to emerge only after bypassing the fan.

"It is extremely tough, and it is extremely elastic, it is not invaded by water and fire, and it is not broken by knives and guns, this is undoubtedly ice silk. Snow Girl affirmed.

Tang Feng hurriedly took the fan out of the fire, looked left and right, and still didn't find any damage to it. I found a treasure, Tang Feng thought to himself.

"No wonder it's so cool when the wind blows. Uncle Xiao sighed with emotion on the side, rolled his eyes and said, "The wind is less, return this fan to me." ”

"Dreaming. Tang Feng refused, "This was originally the young master's trophy, but then again, what do you want to do with a delicate fan? ”

Uncle Xiao touched his arm, which was thicker than other people's thighs, and he was sad for a while.

Uncle Xiao didn't particularly want this fan, but when he picked it up, it was not only cool, but also had a feeling of pure spirit, and he didn't particularly check the texture of this fan at the time, and after using it for a long time, he casually threw it to Tang Feng.

"Not only is the material of this folding fan valuable, but the fan bone is not an ordinary thing, it seems to be forged by the fusion of thousand-year-old cold iron and some other materials. The Snow Girl frowned slightly, "It's strange, such a folding fan that is enough to be called a heavenly soldier level, why haven't you heard of it before?"
