"Hang this head in front of the camp gate." Lu Yu said loudly.
Immediately some soldiers responded and went out holding the old man's head.
Lu Yu looked at the people in the distance and said, "Come here, separate these people and check their identities one by one."
A group of soldiers surrounded these people and trapped them in an open space.
There are specialized people to examine them. After several changes just now, everyone has become very careful and rigorous, for fear that spies from the Tang Army will sneak in.
Fu Zhixue glanced at the scene and said in a deep voice: "Li Mi wants us to be tired of dealing with it. I'm afraid that attacks like this will never stop."
Lu Yu nodded, he also knew Li Mi's purpose very well.
The Tang army was unable to win a field battle against Dayu's army outside, but they did not intend to stop. Instead, they planned to use some means from the beginning to find Dayu's army's flaws.
"Of course we can't sit still and wait for death! Send me an order to pile up all the spirit stone cannons so that Hulao Pass can hear the sound tonight." Lu Yu said loudly.
Song Qinhu chuckled: "Tonight, Tang Jun has suffered a lot."
As Lu Yu's order was conveyed, countless spirit stone cannons were pushed up.
The Qianlong Army marched this time without bringing anything else, but they brought a lot of offensive ordnance, and almost most of the items they carried were offensive equipment.
The spiritual stone cannons were loaded quickly, and in the dark muzzles, surging spiritual energy was gathering.
Boom! Boom! Boom!
There was a shocking sound on the ground!
Tens of thousands of spirit stone cannons fired at the same time, and the dense cannon light spread across the starry sky, illuminating the Hulao area like daylight.
At Wanli Hulao Pass, a huge and magnificent barrier appears. This is the city defense formation of Hulao Pass, and it is extremely strong.
The light of each spiritual stone cannon can destroy a high mountain in an instant, but it is blocked by the formation in front of it.
The golden light of the formation is formed by the convergence of light pillars rushing out of hundreds of formation pavilions, and the mysterious text of the formation flashes from time to time, which is unpredictable.
This is what was left by the strong men who originally built this formation. After countless years of brilliance, the strong men of all generations will leave a trace of mana and cast it into this formation, making the entire formation indestructible.
The powerful spirit stone cannon's light was blocked by the formation and could not break through the city.
But even so, the Tang army still felt as if they were facing a formidable enemy. They woke up from their sleep one by one and came to the city wall with weapons in hand.
"Hahaha, Tang Jun is out. It seems they won't have a good night's sleep today!" Everyone clapped and cheered.
The spirit stone cannon was raging in the air. This power, even with the protection of the formation, still made everyone in Hulao Pass feel in danger.
Lu Yu said: "Our army must ensure rest and maintain peak condition at all times. The spirit stone cannon will continue to fire, and the rest of the people will go down to rest."
The next moment, Lu Yu's pure voice echoed throughout the entire battlefield.
This sound even overshadowed the sound of the artillery outside. Many soldiers of the Dayu Army were already exhausted after running for a long time. They lay down and fell asleep directly.
After all, monks are also human beings. Anyone who is in a high-intensity battle for a long time will feel tired.
With the help of Qingxin Daoyin, everyone immediately fell into a peaceful sleep.
For people's spiritual practice, rest is particularly important. If you don't get enough rest, you will be in low spirits and will not be able to do well no matter what you do.
Some children of wealthy families often hire specialized masters to nurse them back to sleep to ensure they are at their peak energetic state at all times.
