Ouyang Fei listened to Yan Wangqing's question and sighed, "Commander Yan already has the answer in his heart, doesn't he?"

Speaking of this, Ouyang Fei looked up at the top of the tent and said quietly: "Bukong has saved me three times, I have returned him five times, Yebei has saved me six times, he is a madman, in order to save me can not have his own life, I still owe him two lives." ”

"Yan Shuai has saved me twelve times, but I haven't paid it back once, I have to pay off these things I owe them so that I can betray them with peace of mind, it's just ...... Can it really be...... Peace of mind?"

After saying this, Ouyang Fei looked at Yan Wangqing again and said, "Commander Yan, this is the deepest thought in the heart of this undercover agent. ”

"I know that you have suffered betrayal, so you hate betrayal, but this person has not seriously betrayed Cangyun, I hope that Commander Yan can solve this matter perfectly. ”

"What's his name?" Yan Wangqing still asked persistently, she still didn't want to believe it until she heard the name with her own ears.

Ouyang Fei sighed: "His name is Song Twelve, and later after he defected to Yanmen Pass and went undercover in Cangyun, he changed his name to ......."

Before Ouyang Fei finished speaking, a low male voice came from outside the tent, "Change your name to Song Senxue." ”

"......" Ouyang Fei was silent, it turned out that it was him who was standing outside, no wonder he couldn't control his breath and leaked his whereabouts.

Yan Wangqing's hands suddenly clenched, staring at the door of the tent, but saw Song Senxue calmly carrying the tray into the tent, slowly walked to the long table on the side, and put the tray down.

Then he turned to Yan Wangqing and said: "Yan Shuai, you have an injury on your body, and you didn't eat last night, this is the snow ginseng chicken soup I made for you, you can drink it while it's hot!"

Ouyang Fei noticed that after listening to Song Senxue's words, Yan Wangqing's fists gradually let go, and he nodded lightly.

Ouyang Fei hugged Yan Wangqing and said, "Commander Yan, take your leave first, you have a good rest." ”

Yan Wangqing didn't look at Song Senxue, nodded to Ouyang Fei, and said lightly: "Ou Daxia walks slowly, thank you for telling me the truth." ”

Ouyang Fei sighed and shook his head, turned around and walked towards the tent door, when he arrived at the tent door, Ouyang Fei said lightly: "Brother Song, your enemy has always been just the Li family, and has nothing to do with anyone else, Datang is Datang, Li family is Li family, and Cangyun no longer belongs to anyone, Cangyun ...... It's just a cloud. ”

After speaking, he walked out of the tent, and Song Senxue silently turned to face the tent door after carefully chewing Ouyang Fei's words, and shook his fists deeply.

......

Song Senxue's glance Ouyang Fei naturally didn't know, and he didn't know what Yan Wangqing and Song Senxue said, as if it hadn't happened.

Yan Wangqing didn't know anything, Song Senxue still walked around the camp as usual, and at the same time happily boiled chicken soup for Yan Wangqing.

It's just that Ouyang Fei found that Song Senxue's eyebrows seemed to be much brighter, not like before.

And when he met Ouyang Fei, he would also greet him warmly, and Ouyang Fei could see that he had a grateful look in his eyes.

It seems that he has figured it out, he should have made the right choice, right? In this way, Ouyang Fei did these things that didn't seem to be of any benefit to him, but Ouyang Fei was willing to do it.

If nothing else, just be comfortable in your heart, the so-called hard to buy is happy, no matter what you do, as long as you can make yourself feel comfortable in your heart, then it is worth doing, this is Ouyang Fei's values.

The four-wheeled carriage was in full swing, and Ouyang Fei would occasionally take Tang Wuying to the workshop to have a look and give some suggestions to the craftsmen.

Ouyang Fei came from a later life, and the mechanical engineering he knew and the mechanical skills mastered by Tang Wuying were fundamentally the same thing, so the two had a common language.

Ouyang Fei put forward the idea of rolling bearings to the craftsmen, this invention is amazing whether it is Tang Wuying or those Tang craftsmen, the appearance of this thing can be said to be epoch-making, and the scope of its use is too wide.

But at present, rolling bearings do not need to play any other role, and can be applied to horse-drawn carriages.

The inner and outer rings of the rolling bearings and the support frame are carved out of wood, the dimensions are controlled, and then they are printed into a soft clay mold, and the imprints are poured into molten iron to shape, and then the details are polished by craftsmen.

Finally, the iron beads are embedded, and they are roughly formed, but their delicacy still needs to be studied and pondered in the future, but it can be applied temporarily, because it only needs to be used for a day or two, as long as it survives this battle, it doesn't matter if it is broken.

With rolling bearings, not to mention anything else, first of all, it reduces the strength consumption of the person pushing the car, and the wooden bearing of the wheel does not need to rub against the axle seat, but rolls forward with the iron balls in the rolling bearing, and the force required to push the car is naturally much smaller.

And because the friction between the bearing and the shaft seat is reduced, the service life of the bearing will naturally be greatly improved.

However, this rolling bearing is still too complicated for the technological level of this era, and the four that need to be used at present will require craftsmen to polish for a long time, so it cannot be mass-produced for the time being, but it is not something that Ouyang Fei needs to worry about.

The four-wheeled chariot was in full swing, and the Wolf Tooth Army did not launch any large-scale attacks since the defeat in the east of Taiyuan City.

It's just that small groups of elites and military masters are constantly sent to try to infiltrate the city, break through from the city, and at the same time probe the situation of heavy machine guns.

However, Li Guangbi and Li Chengen had expected that the Wolf Tooth Army would have such a move, and sent all the masters to prevent the Wolf Tooth Army from mixing in.

After losing a large number of elites, the Wolf Tooth Army was not for nothing after all, at least Shi Siming knew that there was a big killing weapon called "Metal Storm" in the Taiyuan defenders.

But he didn't know what this metal storm was, how it was launched, and how it killed and injured the enemy more than a hundred feet away, which made Shi Siming annoyed.

Yan Wangqing's injuries have fully recovered, and Qi Jin has also woken up, but he is still a little weak due to excessive blood loss.

Gu Zhilan asked Song Senxue for a few holy herbs to replenish qi and blood, snow ginseng, and with the prescription for replenishing qi and blood, she gave Qi Jin a lot of tonic, Song Senxue was a good friend of Qi Jin, and she would not be stingy.

On the third day, Fang Qian, the owner of Xia Ke Island, finally led all the knights of the rivers and lakes to Taiyuan.

Fang Qian is one of the Nine Heavens "Cangtian Jun", the biological father of Dongfang Yuxuan, the lord of the Valley of Ten Thousand Flowers, and Qu Yun, the leader of the Five Poisons Sect, and he is also the leader of the martial arts alliance elected by the knights of the rivers and lakes.

Fang Qian's martial arts are unfathomable, he is one of the peerless masters of swordsmanship, and the only defeat in this life is when he loses half a move in the hands of the sword saint Tuoba Sinan, and there are external factors.

Fang Qian is not only proud of the world in martial arts, but also among the best in other piano, chess, calligraphy and painting, poetry and songs, secret weapons, and Qimen gossip, so he is also known as the world's first strange man.

Ouyang Fei had been curious about Fang Qian for a long time, and as soon as Fang Qian arrived, Ouyang Fei followed Li Guangbi and Li Chengen to greet him.
