The two flew downstairs, more than 20 Guigu Daoists and the classmates who guarded the wooden box were fighting together, and the three of Beigong Yuheng were also in the battle group, and they didn't see the Baili Yaoguang team, Ashina Yunxuan team, Duanmu Ying and others, it can be seen that they are not the only ones who have been recruited.

"You go and wake everyone up, and I'll resist for a while. Yu Feng said that he raised his sword and stepped forward.

The two of them acted separately, the strength of the attacking opponent was not particularly strong, and the ability of those people in Xiaohuangqiu was about the same, not very difficult to deal with, the only powerful thing was that they were all extremely fast, and it was also not easy to knock down these guys.

Yu Feng secretly lucked, and used a small power version of "Miao Yan**", and the enemies on the line jumped away with a few swishs, and then attacked again.

It's really faster than a monkey, Yu Feng sighed secretly, and then used "Yu Feng with Nothing", trying to make it fast with speed, but he couldn't keep up with the other party's rhythm, and he was half a beat slower each time.

"Think of yourself as a feather, or something that's fluttering, moving with the wind. Beigong Yuheng told Yu Feng about his experience of enlightenment.

It's better to imagine yourself as the wind, formless, colorless, and tasteless, but it does exist, and you can feel it but you can't grasp it......

There is a saying "I don't know the wind to ride me, I don't know I ride the wind", quite a bit of "Zhuang Zhou dreams of butterflies, butterflies dream of Zhuang Zhou" meaning, the mind moves, the wind immediately put into practice, it should be the fierce power of the sky into gusts of wind whistling away, this is the wind sword new move "ride me ride the wind".

The body seemed to become weightless, and the movement of the enemy in his eyes became clearly visible, and they seemed to be repeatedly attacking the defensive circle according to a certain designed route, which was more like harassment than an attack, and often retreated within a few moves.

Most people are trapped by the "ghost press", this is the best time for them to take the mirror, why only see the false tricks but not the real chapter?

Even though the body method is fast, it is difficult to subdue them, and the other party does not fight at all, I really don't know if they have learned the idea of "sparrow warfare", and it is like a tactic in tunnel warfare to change places with one shot.

Just as this cat-and-mouse movement was in full swing, a sudden change appeared, only to hear a loud noise, the land where the wooden box was stored suddenly collapsed, and fell down with four people, and at the same time the dust was flying, the visibility was instantly zero, and the wind jumped into the smoke, but even the hole could not be found.

"I'm going! Is it really the true legend of the tunnel war?" The dust gradually fell, and Yu Feng saw four injured classmates, fortunately, they were all scratches outside the skin, and what made people even more surprising was that there was a fork in the road in this tunnel, and the scene was chaotic when the incident occurred, and no one knew which way the Guigu Dao people were going.

Tunnel warfare is really not something that only existed during the modern Anti-Japanese War, the study of tunnel tactics by the ancient Chinese can definitely be said to be at the world's leading level for a long time, and its highest peak appeared in the Northern Song Dynasty, in order to guard against Liao, Jin and other northern enemy countries, the Song army dug a lot of criss-crossing tunnels.

The Hebei region has discovered a network of tunnels that have been preserved to modern times, with a total length of hundreds of kilometers, covering an area of 1,600 square kilometers, connecting several prefectures and counties into a complex underground Great Wall, compared to the tunnels in the tunnel warfare are much more rudimentary.

"Are you alright?" Xiaoxue had just arrived, and the rest of the people had basically regained their mobility.

In this case, someone will ask you "where is the thing" or "where is the enemy", but Xiaoxue's first concern is always the safety of people, if it weren't for the occasion, Yufeng really wanted to go up and hug her.

"It's okay, a few classmates were slightly injured, and there were two forks in their tunnel, and I don't know where to go. ”

"Split up and beware of ambushes. Baili Yaoguang led people down to catch up.

Coo~ It was a three-legged golden crow, and I saw it shouting a few times to everyone, and quickly flew southwest.

"Follow it!" There seemed to be a subtle connection between the Golden Crow and the Ancient Mirror, and it could not allow the Ancient Mirror to be taken away.

Fortunately, the speed of Beigong Yuheng and Yufeng could barely keep up with Jin Wu, and they ran out for seven or eight miles in a blink of an eye, and not far ahead, you could see a few Guigu Dao people guarding outside a thatched house, which must be where their tunnel entrance is.

Half a day to dig such a long tunnel? Are these guys human? But now I can't care so much, Jin Wu brought them here only to show one thing, the other party has not come out of the tunnel, this is the best opportunity to intercept them!

No matter how much it was, Yu Feng raised his sword in both hands and used all his strength to "look down on the earth", and the strong impact blasted the house and people far away, and the tunnel entrance collapsed immediately.

"What should I do next? Arrest people along the tunnel?" Duanmu looked at the cracks on the ground due to the impact force, and could basically judge the direction of the tunnel.

Bang - the front end of the tunnel can not be supported, collapsed a hole, look inward seems to be very wet, there is water at the bottom of the road, it seems that they also dug out groundwater by the way, the water veins in the Surabaya basin are very widely distributed, there is shallow groundwater is not uncommon.

Xiaoxue arrived in time, and after learning the situation, she unequivocally "Frozen Thousand Miles" immediately came out, freezing the entire tunnel solidly.

......

"Xiaoxue, I knew you did it, thaw me quickly!" Kaori's voice could be heard through the tunnels......

The disciples who opened the door were wiped out this time, a total of sixty-three people, plus the one who was captured before was exactly sixty-four, but he still didn't see the opening rope that had been seen by the dragon all the time, so he must have escaped alone.

"Or ...... Let's find a way to send the ancient mirror to other worlds, and there will always be people who stay here and try their best to seize it. Yumi looked at the ancient mirrors in the wooden box, they were lying in the box safely, and I don't know how many fights there were in the world for this.

"How do you send it?"

"Get Jiang Gui from Qi State. Duanmu Ying and Yumi thought together.

"I have a way to make the ancient mirror play a positive role. ”

Beigong Yuheng's idea was quickly implemented, using the ancient mirror to provide energy for the academy's guardian array, and its stability was indeed improved by more than one grade.

The tunnels of the academy are also basically figured out, there are as many as four, it can't be dug by Guigu Road in half a day, they have an extra shift during the New Year's vacation of Fuyang Academy, and the tunnels are connected to the main buildings of the academy for later use, which also explains from the side why the previous defensive array has become useless.

"Actually, I don't think the tunnel needs to be landfilled, and it would be good to leave a section on campus as a tryst. "Kaori's ideas are always unbelievable.

"Kaori is the only one who is interested in going to the tunnel for a tryst, right?"

"No, don't you think it's exciting? Maybe there's something even more exciting. ”

"Forget it......"
