The formation laid out by Long Kaijiang was like a cover that held Lin Yue in it, and the sound and breath inside could not be transmitted, and the spiritual power outside naturally could not come in.

The whirlpool formed by the Heavenly Dao Exercises could not absorb the spiritual power, and the suction force generated became greater and greater. Long Kaijiang, who was the closest to him, felt in his heart, could it be that Lin Yue wanted to advance to the Sitting Lighting Realm?

Give him a hand!

Thinking of this, Long Kaijiang held Lin Yue's heart with one hand and Lin Yue's chest with the other. The aura is like the Yangtze River, surging endlessly.

Long Kaijiang originally thought that Lin Yue could use how much spiritual power he could use to advance to the Sitting Lighting Realm, at first he had no reservations, but then he felt more and more that something was wrong, why was Lin Yue's body like a bottomless pit?

These spiritual powers can't be said to be a Lin Yue, even if ten advanced sitting realms can't absorb so much. No, things are still weird.

Long Kaijiang thought of this and hurriedly locked the Linghai. There was no longer spiritual power to replenish, and the whirlpool could only disperse helplessly.

However, Lin Yue looked at it again, overjoyed, and opened his eyes and emitted two essences: "Old Xie Long's generous gift." ”

Long Kaijiang looked at Lin Yue, he had lost too much spiritual power, and he was a little weak: "Stop at the Great Perfection of the Spirit Fetus Realm, what kind of exercises do you practice?"

Only then did Lin Yue realize that something was wrong, and seeing that Long Kaijiang was weak, his concern was beyond words.

Long Kaijiang waved his hand: "It's just that I lost some spiritual power, so it's no big deal." It only takes more than a month to be able to cultivate back. ”

Saying this, Lin Yue felt even more guilty, this was wartime, and spiritual cultivation was too important. But it's already happened, and there's nothing you can do about it, even guilt.

Gong Ge hurriedly came: "Brother Lin, all the mines have been prepared, two hundred, but I don't know if they can be exploded." ”

Lin Yue was overjoyed: "Let's go, go over and have a look." ”

When the group came to the outside of the city, the pit for the mine test explosion had been dug, and the gunpowder lead was ten meters long, and it could be extended indefinitely if necessary.

Mines are placed in pits, covered with tarpaulins, and iron slag is placed on them, which are then buried and trampled.

Gong Ge waited until Lin Yue nodded, and then ordered the fire to be ignited. The fuse leaks on the surface and burns quickly after ignition.

A moment later, there was a loud bang, and a large crater with a diameter of three meters and a depth of more than one meter exploded in the buried place just now.

And so it was overjoyed.

Soldiers dig pits to bury mines, and the exposed leads are a paralytic disease, because the leads are too long, and during the burning process, they only need to cut the leads, and the mines are useless.

If it is buried in the ground, it will cause the lead to go out due to moisture or lack of oxygen.

Therefore, it is not advisable to bury mines in the center of the battlefield. At least until the pressure hair mine is made, it is not advisable.

Lin Yue ordered someone to cut the gunpowder lead short, and it was available in various sizes.

Then the fire recorded the length of time it took for the mine to ignite, and he thought that if it was not buried, it would be possible to send the mine out with a trebuchet or a ballista.

The eight centimeters of the exposed lead is just right, and it ignites before the trebuchet throws the mine, and after flying three to four hundred meters, the mine explodes in the air.

Of course, the ground should also be buried, but only away from the center of the battlefield, because the longer the lead, the more likely it is that there will be an accident and it will not sound.

It reduces the lethality and increases the success rate of detonation, which is not difficult to decide, as long as it is exploded, it will deter the enemy, even if it does not kill the enemy, it is also useful.

Lin Yue experimented with the crossbow again, but after tying stones of the same weight to the arrow crossbow, it failed.

The arrows fired by the ballista are two meters long, the thickness of the wood at the mouth of the cup, and the tip is sharpened, and due to the huge power of the ballista, it is often possible to string the enemy with a single crossbow arrow.

Of course, it also has a role, which is to break through the enemy's shield array.

When a mine is tied, it increases the weight of the arrow, and it is not easy to operate, and if it is tied to the head, the arrow will lose its balance and be tied in the middle, and the mine will get in the way when firing.

Lin Yue muttered in his mouth, if it was not a crossbow arrow that was sent, but a bomb, then the effect of this crossbow cart would be great.

Come to think of it, the weapon development cycle is too long, and even if it is made, the quantity is too small, and it will not be effective.

In addition, the research and development of weapons must be left behind. Whether it is a mine or a bomb, as long as you understand the principle, it is not difficult to make, such as the Blood Clan's imitation firearm, which only took a short time.

Qingfeng City has been truces for seven days, and the next wave of the Blood Clan's offensive will not be too far away.

The loud noise outside the city alarmed Wei Zexiong, and when he went out of the city to check, he saw Lin Yue and Gong Ge discussing how to bury the mines and how far apart.

Lin Yue personally picked up the shovel and dug the pit and showed the soldiers how to bury it was the most reasonable.

The son died in the hands of Lin Yue, but Lin Yue was such a person, and in several battles in Qingfeng City, Lin Yue was there, and he had outstanding achievements.

"I, Wei Zexiong, love talents, heavy heroes, as long as I can kill the men of the dark race, I Wei Zexiong will respect them. But Lin Yue, Lin Yue, why did you kill Yuan Liang? How do you let the old man ignore this murderous revenge?"

Wei Yin said: "Family master, I have found Kong Liwu." Do you see him now?"

Wei Zexiong shook his head slightly, and then sighed. Knowing his son Mo Ruo's father, even if Wei Zexiong guesses, he can guess one or two.

Kong Liwu was still under the city and shouted: "City Lord Wei, the guard that Wei Gongzi brought that day was hit by the sword in the back. ”

After hearing this, Wei Zexiong's face was really joyless and angry, and at this moment, he seemed to be more than ten years old.

Without saying a word, he got down the city wall and slowly walked back to the city lord's mansion. In the ancestral hall, he looked at Wei Yuanliang's tablet without saying a word.

Such a night, Wei Zexiong's black hair turned white.

In the early morning of the next day, Song Yihe arrived with his troops, and the first thing he said was the rebellion of the Cao family, which Wei Zexiong had already known.

Song Yihe frowned: "What does the City Lord of Wei plan?"

"Defend Qingfeng City. ”

"Lord Wei City, the fourteen cities north of Yinshui are rebelling, they are on the verge of rebellion, and Qingfeng City is a lonely city. You can't defend it!"

Wei Zexiong said: "The Lu of the food monarch is the matter of loyalty to the monarch." When I Wei Zexiong came to Qingfeng City, there were only eight members of the family, and now the Wei family is eighty-five. ”

……

The person from the Xizhao Courtyard was called Lin Yue, Ye Jingze went out to inquire about the news for more than half a month, and finally returned; He Weidong and Ba Zhiyong also just arrived.

Lin Yue asked Gong Ge to continue to supervise the work and returned to the Xizhao Courtyard.

He Weidong, Ba Zhiyong, Lan Shuying, Jin Xiong, Mo Beichen, Lan Qingqian and others and other mercenary groups were all there.

At this time, Ye Jingze was greeting Jin Xiong and others, Lan Shuying and Lan Qingqian sisters had been separated for fifteen years, and they met again, holding hands and talking, and the sunset courtyard was very lively.

After Lin Yue came back, everyone's eyes were on him.

Lin Yue frowned and looked at Lan Shuying: "Shuying, you are not ......"

Lan Shuying suppressed her emotions, she swore that Lin Yue would not marry in this life, but there were too many people, and she couldn't spit out her heart at this time.

Lin Yue looked at He Weidong and Ba Zhiyong again, they were so embarrassed, and they came back together, there must have been a lot of twists and turns.

He Weidong said first that the Lin family and the Cao family rebelled, Lan Shuying ran away from marriage, Lan Yexiao handed Lan Shuying to himself and went to Lingnan City.

On the way to Qingfeng City, two blood clan troops and a werewolf army intercepted them, fighting all the way, and it was really not easy to come to Qingfeng City.

Lin Yue's heart sank, and Lan Ye smiled at this point in time to lead Nancheng, there was more than one luck!
