After confirming that the first step of the plan was successful, Lin Ziming did not rush into the underground mine, but asked the Dark Shadow to clean up the kobold corpses on the ground, and eliminate the traces of the battle as much as possible, and then looked at the third wooden house.

"This should come out." Lin Ziming calculated the time in his heart, and according to his previous observation below, the entrance and exit of the third wooden house at this time should be the time to dispose of the slag.

As soon as he finished thinking about it, the door of the wooden house was pushed open from the inside out, and four kobold miners pushed four tattered mine carts full of rubble out of it, and they were going to carry the slag outside and dump it, every forty minutes, more than twenty times a day, and before they could find that there was no one outside, they were easily killed by Lin Ziming, who was waiting on the side.

Lin Ziming simply hid the corpse, he didn't need to hide it very carefully, because the angle relationship between the wooden houses was not easy to observe each other, he only needed to let the kobolds who came out of each wooden house not notice the abnormality at the first time, and it would be too late for them to find out something wrong after they walked out of the wooden house.

Lin Ziming waited outside for half an hour to kill the kobold miners who were responsible for carrying the gravel in the remaining three entrances and exits, his real purpose was not all for these porters who would make a regular trip to the surface, his main purpose was these rectangular iron carts, which would have an impact on his second step plan.

Feeling that the Dark Shadow sent out earlier had arrived at the preset location, Lin Ziming was about to start his second step plan.

After four hours of observation, Lin Ziming made a detailed attack plan and prepared several contingency plans.

Of course, he will not be stiff to carry out the plan, the best way is to improvise according to the development of the situation, the plan is only to better achieve the goal, fortunately, so far, the offensive plan is going very smoothly.

The plan for this attack on the kobold camp was divided into three steps.

The first step is to get rid of all the patrols and guards on the ground without the kobolds in the mine noticing, and to clear out the four kobolds who are responsible for carrying the rubble, and to do it when they come out to clean the stones, so that the minecarts carrying the stones will also be left outside, and the current first step plan has been successfully completed.

Before talking about the second step plan, I must first explain the details of Lin Ziming's observation of the mine through the dark shadow in the past 4 hours, the area inside this mine is very large, and the passages are intricate, and there are only four entrances and exits in the mine, corresponding to the four wooden houses above.

There is a relatively large mining point under each entrance, there are a total of four mining points, these four entrances and exits may be built according to these four mining points, most of the kobold miners in the periphery are working in these four mining points, and the more than 100 kobold miners he observed are only the number of one of the mining points, that is to say, there are more than 400 kobold people in these four mining points alone, which is not counting the number of kobold people inside the pit.

There are many dead ends and forks in the tunnels, but eventually all of them converge into a tunnel that leads to the inside of the mine, which is so long that the Dark Shadow can float through it for more than a minute.

The area inside the pit is not large, and there are more than 40 kobold miners in it who are mining, compared to the mining methods of those kobolds outside, these kobolds inside are much more cautious and professional.

They carefully excavated the stones from the walls with small shovels, and from time to time used brushes to clean the dust from the walls, saying that mining looked more like excavating cultural relics, and if it weren't for the piles of debris under them, and the thumb-sized black crystal that a kobold miner mined from time to time from the stone wall, Lin Ziming really thought they were mining some ruins.

Behind these miners, there is a blue-gray stone gate that is very inconsistent with the surrounding environment, and it is not known why this stone door appeared in a mine, this stone door was forced open by an external force, which can be seen from the impact crack in the center of the stone door.

There are two kobolds guarding on both sides of this stone gate, looking at their physique and equipment are very similar to the kobold leader, but they are a little shorter, and the weapon is not the mace of the kobold leader, but a double-edged battle axe in his right hand and a shield in his left hand.

The violent impact sound came from inside the stone door from time to time, but it was very strange that there was such a powerful impact sound, but until now it was very close to the place where the sound was generated, and I didn't feel a trace of tremor on the ground.

Although very curious about the situation inside, the Dark Shadow has not yet been able to sneak in from under the noses of the two professionals, and it has almost been spotted a few times when it has penetrated here, but fortunately it has avoided it without danger.

Although there are two more kobold professionals, as long as the plan goes well, Lin Zimingjue's own win rate is still very high.

The second step of the plan is to let the dark shadow sneak into the tunnel connected to the outside of the mine, and the dark shadow only needs to pinch the last intersection point between the outer passage and this tunnel, so that all the kobolds on the periphery of the mine must pass through here if they want to enter the inside, and the entire inside and outside of the mine is the noise of mining, and the tunnel is relatively long, and the sound of fighting and fighting at the beginning is difficult to reach the inside of the mine for a while, and when the kobold inside notices that something is wrong, his second step plan will also succeed.

With the advantage of the small terrain, the level 15 Dark Shadow can completely do it in one fell swoop, and the Dark Shadow also carries a few compressed poison mist grenades filled with poisonous mist to deal with possible emergencies and ensure that all kobolds who want to pass through here are blocked.

And he only needs to seal the four entrances and exits with a poisonous mist, and then kill the kobolds inside as much as he can, and drive them as much as possible to the interior if he can't kill them, and then as long as the dark shadow can hold on, he has his own way to deal with them.

Since the four entrances and exits are sealed, and then the dumpling making tactics are carried out with the Dark Shadow, then why do you need to wait until the four teams of kobold porters are killed, and it is not enough to directly block them with poisonous mist, and kobolds below level 10 can't withstand the corrosion of poisonous mist at all.
