When Diego came to the northern exit of the Valley of the Snakes, he was surprised to find that a continuous wall appeared in front of him as if by miracle.

The wall stretched at the northern end of the canyon, forty or fifty meters wide, and the mouth of the valley was tightly blocked, and the height of the highest place was more than two meters, and about five companies of dwarves were busy on the wall, and it seemed that they were still planning to build it higher.

In the middle of the low wall was a doorway more than one person high, and Diego noticed that there was no door panel on the doorway, and the hole was open. The dwarf Brian Copperbeard is standing beneath the doorway, waiting for him to arrive.

"Man, I'm too late," Brian said apologetically, walking up and giving him a strong hug, "we've been plagued by demons since the morning, and it wasn't until near noon that we were sure they were just feints!" We ended up rushing down the polluter heights, and guess what? One charge will kill them all! ”

"It's not too late for you to come, I deliberately left two more legions of demons for you to cut down!" Diego said solemnly, as if these demons were really left by him for the dwarves.

"......" Brian was stunned for a moment, then laughed with Diego, "We're going to cut it off!" ”

They passed through the doorway and came behind the wall. More than a dozen assembled steam tanks lined up behind a low wall, and a few gnome technicians were busy adding lubricant to the tanks and making final preparations for start-up. The Baggage Company of the Moon Creek Brigade was busy replacing the damaged armor and weapons for everyone, and at the same time delivering hot food and water to everyone—people had been starving since the morning.

"Hey, Diego, there was so much commotion just now, I almost wonder if you blew up the entire canyon!" Masrae Bearskin strode over and handed him half a steaming ham in his hand, "Oh, it's yours!" ”

Diego took it casually and took a bite, well, it tasted good, but it was a little salty.

"I did blow it up!" He chewed a few bites, then swallowed, and then said lightly, "I built a canyon mausoleum that is seventy or eighty meters long, and buried at least half of the demons of the legion underneath!" ”

"Hey, well done," Masrae thought for three or four seconds before he realized what that meant, "I haven't killed as many dragoons with the Storm Whip all morning!" ”

"Wow, that's great!" Brian also shouted in surprise, but what made him happy was something else entirely, "You've bought us at least two hours, and with these two hours, we can at least raise this wall by another half a meter!" ”

They ascended the city walls along the ramp behind the walls. Despite the rush of time, the walls were crudely built, but they were still sturdy and sturdy, wide enough for four people to walk side by side, while on the side facing the valley were sleek and flat, with stones of various sizes fitting so close that there was little to climb.

"Time is running out!" Brian stomped the rocks on the soles of his feet to determine if they were strong enough, "The rocks here are solid, and the ground beneath the walls is so solid that I can clearly feel their strength with my feet when I walk over them." If we were given three months, nay, only a month, I would be able to build this wall more reassuring than the walls of the Overwatch! ”

"I'm sure you can do that," Diego nodded, picking a smooth stone and sitting down, "Dwarves are naturally excellent builders, and if anyone can build a solid wall in such a short time, I can't think of any other race except dwarves." Truth be told, I'm glad you're standing by my side with an axe, and if there's anything else I could hope for, it's to see more of your fellow citizens standing here! ”

This compliment to the dwarves made Brian very happy, and for a moment, how he longed for a whole line of demons to stand in front of him and let him cut down!

To his disappointment, however, they didn't see a single demon emerge from the canyon until it was getting dark. It seems that Diego has caused more trouble for the demons than he thought.

Time passed slowly, and it was completely dark. Today is the day when the White Lady and the Blue Child rest, and the whole canyon looks dark. In order to prevent the demons from sneaking attack, several blazing bonfires were lit on the flat ground outside the city walls, and the valley mouth was lit up as bright as day. Most of the soldiers of the Moon Creek Brigade, who had fought fiercely for almost the entire day, had sunk into their dreams, and the griffons had also fallen asleep on the cliffs on either side. The Hammer Dwarves hid themselves under the warm wings of the griffons, and they slept soundly like chicks.

Only the Copperbeard Dwarves were still working, this rock-like tough race almost never knew what exhaustion was, and only wanted to build the walls higher, and the human soldiers who were beating them down were almost foaming at the mouth, but they kept focused, and they didn't even slow down in the slightest. By now, the height of the wall was more than three meters, and they were building the breastwall, the last part of the wall, which allowed the defenders to hide from enemy arrows and spears in the back.

As the clock approached midnight, it was dark, and the hot, humid air predicted the coming storm. Suddenly, deep in the canyon in the distance, a burst of ping-pong gunfire suddenly rang out. Immediately afterward, several human cavalry rushed out of the canyon and galloped towards the side of the city wall. It was a scout team that Diego had sent into the canyon, but there were only three of them left.

"They're coming!" As they approached the wall, they shouted, "Three legions of demons, covering almost every inch of the canyon, but we've taught them a hard lesson: don't bring torches!" ”

Above the city gate, Diego, who was pretending to sleep, sat up.

"Heralds, blow the horn and get everyone ready for battle, the griffon knights take to the skies and scout the enemy's depths!" He commanded loudly, and he finally turned to look at Brian Copperbeard, who was rubbing his eyes, "Old man, let your men put down their pickaxes and hammers, put on armor and battle axes, and get ready to cut!" ”

Beneath the doorway, a steam tank rolled up and blocked the gate tightly, and the thick barrel of the cannon sticked out of the door and aimed into the canyon.
