Chapter 259: Initiate Phase 1 Cleanup Plan

The main reason is that Zhang Yanhang felt that he might encounter some special circumstances on the way, such as the one that was only separated by a wall, but gathered dozens of red iron ants that were constantly moving to the distance. If this is the case, Zhang Yanhang He will activate the death wave skill because he is afraid that they will have escaped when he arrives.

In this way, Zhang Yanhang's physical exertion will naturally be increased, and his battery life will be correspondingly reduced.

Nothing can be completely smooth sailing. Therefore, it is precisely because of the occurrence of certain unexpected factors that Zhang Yanhang deliberately estimated his battery life by a few miles. Otherwise, he would have estimated the duration of seven hours Battery life is actually pretty normal.

While Zhang Yanhang was thinking about the battery life, a red iron worker ant jumped down from the top of the cave. While hanging in mid-air, Zhang Yanhang stretched out his right hand and pinched its neck.

Click!

Accompanied by a crisp sound of the exoskeleton shattering, the red iron worker ant's neck joint broke, and the head fell directly to the ground, while the body part was thrown aside by Zhang Yanhang.

[Successfully kill the first-order one-star monster 'Red Iron Worker Ant (Normal)' x 1, soul point +3. 】

After killing the red iron worker ants who just wanted to make a sneak attack, Zhang Yanhang stood there and waited silently for a few seconds.

Although the movement speed has been greatly increased due to the promotion to the second level, the refresh time of the treasure chest is still the same, which continues to trouble Zhang Yanhang.

Just like now, obviously only one monster has been killed, but he still has to stand obediently and wait for the treasure chest to be refreshed. This kind of behavior is quite a waste of time, but he can't do it, because the most important thing to him is is the income of the treasure chest.

If you can get a treasure box every time you wait, then Zhang Yanhang has absolutely no complaints about the time spent waiting for the treasure box to be refreshed, but unfortunately, most of the waiting will not be exchanged for any rewards, it is just a waste of time That's all.

In the past, only one red iron ant would drop a treasure chest, but now it has become twenty red iron ants that would drop a treasure chest. This caused Zhang Yanhang to waste more time waiting for the treasure chest to be refreshed. , if the treasure chest can be refreshed immediately after the monster dies, then Zhang Yanhang's hunting efficiency will definitely be greatly improved.

After waiting for a few seconds, the corpses of the red iron worker ants on the ground still showed no sign of refreshing the treasure chest, so Zhang Yanhang could only sigh silently, and then ran to the distance again.

…………

ten minutes later,

Just as Zhang Yanhang expected, he successfully cleared the area closest to the C-shaped passage. Currently, there is an area of ​​39 square kilometers short of clearing the entire red iron ant nest.

By the way, after Zhang Yanhang cleaned up the area just now, he started a self-selection, and re-explored the road to the cave where the refined red iron was piled up by pausing time.

Don't get me wrong, it doesn't mean that Zhang Yanhang got lost, that's impossible, he just divided the area that needs to be cleaned up this time.

Counting the area that has been cleared, Zhang Yanhang divided the next first phase of the clean-up plan into eight areas in total, and the average area of ​​each area is about one square kilometer.

Therefore, if Zhang Yanhang wants to complete the first stage of the red iron ant nest cleaning plan and go to the red iron cave to upgrade the Four Great Jiekong Jingshiquan, he must continue to clean up an area of ​​seven square kilometers.

"For an area of ​​seven square kilometers, if calculated based on 40 minutes per square kilometer, it will take about 280 minutes, which is about five hours." Zhang Yanhang remembered that the transmission channel seemed to only last for a total of six half an hour.

And when Zhang Yanhang was in the main world, he had already wasted half an hour in running the Qiankun Wuji Kungfu to restore energy value, so when he first entered the red iron ant nest, there were actually only six hours left in the transmission channel. The duration is over.

Then these six hours were consumed by half an hour to deal with the more than 2,000 red iron ants that besieged him because Zhang Yanhang was besieged by red iron ants just after he entered the red iron ant nest.

Afterwards, Zhang Yanhang spent another half an hour digesting the harvest brought by killing more than 2,000 red iron ants, and by the way, he recovered his energy value by running the Qiankun Wuji Kung Fu.

"Based on this, before I officially started cleaning up the red iron ant nest, the duration of the teleportation channel was only five hours.

In addition, I spent 40 minutes of cleaning time for cleaning the first area just now, so the current teleportation channel actually only has a duration of four hours and 20 minutes, but I cleaned the remaining seven pieces. The area needs to consume at least four hours and forty minutes.

Fortunately, I asked the school for leave before, otherwise, if I can only clean the red iron ant nest during the time when the teleportation channel is open, I can't even complete the red iron ant nest cleaning plan in six hours the first stage. "

Zhang Yanhang felt that his request for leave before entering the red iron ant nest was quite prescient. Otherwise, it would be too troublesome if he could only hunt for a few hours each time and had to wait another five days. Moreover, Under normal circumstances, this would seriously slow down his promotion to Tier 3.

Of course, in some extreme cases, it is also possible that Zhang Yanhang has already been promoted to the third rank, but this small red iron ant nest Dalagu has not been cleaned up. This is very possible.

Zhang Yanhang estimated the promotion time for himself to be three weeks or one month, but the transmission channel leading to the red iron ant nest can only last for six and a half hours each time.

Even if it can increase the duration by half an hour every time it is opened, Zhang Yanhang still needs to wait at least three opening cycles, that is, fifteen days to get together the twenty-seven hours needed to completely empty the entire red iron ant nest. .

Fifteen days is already equivalent to two weeks. If Zhang Yanhang's promotion to the third rank is faster than he expected, for example, a week earlier, and it took only half a month to advance to the third rank. It may happen that he has been promoted to the third rank, but the red iron ant nest is still not empty by love.

It was precisely because this aspect was considered from the very beginning that Zhang Yanhang was already prepared to stay here for five consecutive days.
