Seeing that the second wave of dwarves had all fallen, Forging Heaven couldn't wait to rush back to the top of the highlands.

"Brother Lei, what the hell are these? Red name! Red name! This is a Commander! Do you know? Commander! ……”

Forging Tian's mouth is like a train, rumbling endlessly.

Lei Zhen knew that if he let him continue, he might not have time to do anything else today, so he hurriedly opened the attributes of the skeleton mage and let Forging Tian see it himself, which stopped Forging Tian's mouth.

"Damn, it's a commander-level creature, and its attack is even higher than that of a skeleton archer. I'll go! Top Night Blessing, the attack can be strengthened by 200% in the dark state, which is simply a shotgun change. Forging Tian roared, and the thunder shook his ears and hurt.

"Alright, the third wave of mountain dwarves is coming, hurry back to your position." Lei Zhen really couldn't stand Forging Tian's loud voice, so he found a reason to drive Forging Tian to the front.

According to the rhythm of the second wave of attacks, Lei Zhen successfully cleared the third wave of mountain dwarves. It's just that this time, because he mastered the law of up and down attacks, when the mountain dwarf entered a distance of 120 meters from Lei Zhen, he let the skeleton mage attack. By the time the third wave of mountain dwarves were all killed, there would still be more than 20 meters away from the Great Goblin Force of Forging Heaven.

At this time, Lei Zhen found that in the place where the third wave of mountain dwarf troops died last, a familiar seven-colored circle of light appeared, which was the supply array. Originally, Lei Zhen was ready to take advantage of the fact that the troops did not incur any major losses and temporarily withdraw from the dungeon, but the appearance of this supply aperture changed his mind.

Hurriedly beckoned Forging Tian to rush towards the direction of the supply aperture with the troops, Lei Zhen asked Forging Tian as he ran: "Forging Tian, since you have an S-level forging talent, you must be very familiar with the various blacksmith shops in Han Bingcheng, do you know that the blacksmith shop sells ammunition trucks?" ”

That's right, Lei Zhen was thinking about whether to temporarily withdraw from the dungeon and buy an ammunition car. In Heroic Legends, there are four types of war machines: ballistas to assist in attacks, trebuchets to attack walls or gates, medical tents to heal wounded troops, and ammunition carts to replenish ammunition.

"Brother Lei, don't you know that war machinery is only sold in cities of big cities and above, and it is said that they are strictly controlled by the official forces of each camp, and they will only be sold to people who have made outstanding contributions to their own camp, as if they need some points or something." Forging Tian glanced at Lei Zhen, and then said.

"Is it honor points?" As soon as Lei Zhen heard that he needed to contribute, he immediately thought of the honor points he had not yet received.

"I don't know much about this, I just heard the blacksmiths talk about it, and I didn't pay much attention to it at the time." Forging Tian said honestly.

Knowing that in a short period of time, the ammunition truck should not think about it anymore, Lei Zhen returned his attention to the dungeon. Now that there is a supply array, it means that the first level has passed, and Lei Zhen is now afraid that the second level will really be what he guessed, if it is really to attack the mountain after a while, it will become extremely unfavorable for them.

Sometimes it's just a good spirit, a bad spirit. After Lei Zhen and them came out of the supply array, the system really reminded them that the second level was to break through the three lines of defense on the northern mountain and reach the top of the mountain.

Just as Lei Zhen was frowning and thinking about tactics, Forging Tian on the side suddenly said: "Brother Lei, have you noticed that the speed of our troops when they go up and down the mountain seems to be different, and it is a lot worse. ”

"Huh? yes, I'll take a look. "Don't say it, Lei Zhen took a closer look at this time, and sure enough, he found that the speed of the troops when they went up the mountain and when they came down the mountain were not the same, the uphill was obviously a little slower than usual, but the downhill was a little faster than usual.

"When the mountain dwarves attacked just now, how did I remember that their speed was the same?" Lei Zhen muttered.

Suddenly, Lei Zhen clasped his hands together and said loudly: "I understand, the speed of going up and down the mountain should be the same as the attack distance of the previous ranged troops, with corresponding strengthening and weakening. This is the same as in reality, going up the hill to reduce the speed, going down the hill to increase the speed, but it should not have a big impact. Now there are Great Elves, Skeleton Mages, and Skeleton Archers in the troops, and the speed of the three classes is different, which is 5, 4, and 3. But now there is no significant increase in the spacing between the front and back, which means that the speed at which they increase or decrease is the same, and the effect of going up and down is a fixed value. ”

After a pause, Lei Zhen's confident voice sounded again, "And the reason why I haven't found this pattern in the mountain dwarves is because the mountain dwarves, who have lived in the mountains for a long time, have adapted to this law and found a way to deal with it. As a result, they are no longer affected by the law of deceleration when they go up the mountain. ”

Another pattern was discovered, which made Lei Zhen very excited, but in an instant he became frustrated again, because he found that this rule seemed to be of little use to the current situation, and made his own disadvantage even more obvious. Mountain dwarves are not affected by slowdowns on climbs, but they can't.

Just as Lei Zhen was thinking nonsense, they had already come to the foot of the mountain to the north. As the saying goes, looking at the dead horses running on the mountain, looking at the short distance, but by the time they reached the foot of the mountain, it was already completely dark.

Lei Zhen found that there was only one way up the mountain, and it was relatively narrow, and if the troops wanted to go up the mountain, they had to go up in turn. This is not good news for them. It's a completely one-man and excellent defensive terrain.

If it is in reality, Lei Zhen can also use strategies such as setting fires and besieging mountains to cut off food, but it doesn't work in the game.

"Brother Lei, will you go up the mountain now?" Seeing that Lei Zhen stood in front of the mountain road for a long time without moving, Forging Tian couldn't help but ask.

Lei Zhen saw Forging Tian open his question, so he told him his concerns: "Forging Heaven, we are all long-range troops, attacking the mountain will reduce the effective attack distance of the troops by 50%, and the mountain road is narrow, it is impossible for us to completely spread the troops, which will disperse the firepower and make it impossible to form a concentrated fire attack." The most important thing is that our travel speed will be reduced by about 1 point, but if the other party sneaks up on us, the speed will increase by 1 point, so our advantage will not be at all. ”

Forging Tian thought for a while and said to Lei Zhen: "Brother Lei, my big goblin has 5 points of speed, and even if the speed is reduced, it has 4 points, which is the same as that of the mountain dwarves after being strengthened. In this way, I will go first and attract the attention of the enemy. When I engage with the mountain dwarves, you're attacking from behind. It's night, and I believe that with the powerful attack power of the skeleton mage, even if it can't form a concentrated fire, it is not something that the mountain dwarves can withstand. ”
