Guarding a reservoir? I am guarding the river of time!

The black wooden boat was at a river crossing, and when it turned around, it hit a dam.

Because Su Mu's attention was all on controlling the water flow and the speed of the boat, and the vision at the corner was limited, he did not notice that there was a stone dam in front of him, and he just hit it.

Fortunately, this boat is relatively strong, otherwise, with this speed and this impact, the general boat would fall apart on the spot.

At this time, the skinny old man came forward, and without saying a word, he slapped the "little ghost" who was pointing the way: "How did you point the way!"

This sudden slap also stunned the little ghost, and he felt so wronged!

He clearly pointed according to the previous route, who knew that there was a dam here, but he did not dare to refute, so he could only bear it silently.

"Okay, you have nothing to do."

As he said, the old man threw the little ghost back to the power cabin.

"Senior, it's my fault."

"I remember that when I came here before, there was no dam here. Who knows how there was an extra dam?"

"It's okay. I have a new route."

"It's just that there's a little detour."

After hearing the keyword "detour", Su Mu frowned.

Any situation can be accepted, but Su Mu can't accept detours. How much time will be wasted.

"You step back a few steps."

Su Mu said to the skinny old man.

Hearing this, the skinny old man's heart also trembled. He had a bad premonition in his heart. His eyelids kept twitching, and he subconsciously stepped back a few steps.

The next second, Su Mu took the big hammer in his hand, jumped into the air, and all his spiritual power gathered on the hammer.

Dong——

He hit the stone dam seriously!

Boom!

The dam collapsed instantly, and the river was opened abruptly!

Seeing this scene, the old man opened his mouth and his mind was blank.

At this time, Xiao Niu Ma and Ma were just holding tea and walking out of the cabin. They just happened to see this scene and almost dropped the cups in their hands.

The old man looked at the broken dam in front of him. When he saw the water from two different tributaries converge together, he was completely numb.

This stone dam is a "boundary wall".

The "boundary wall" is very important to the heavens and the worlds, and plays an important role in maintaining order.

This stone dam separates two unrelated tributary river areas, that is, it separates all the worlds in the two tributary river areas, and achieves a state of mutual peace.

Once the "boundary wall" is broken, it means that the passages of all the worlds in the two tributary river areas are all opened.

Then there will be a result, that is, all the worlds in the two tributaries will engage in an endless "world war", either annexing each other or being annexed by each other, there is no third result.

Because once the "chain of suspicion" is formed, it cannot be broken. The other party is afraid that the other party will attack them, so fighting will be inevitable.

"Boundary wall" to a certain extent protects some extremely weak worlds, so that those extremely advanced worlds cannot find them.

Just like the three-body civilization in the universe, once the three-body civilization discovers the blue star, it will be an unstoppable disaster of star destruction for the blue star.

Therefore, Su Mu's move scared the old man silly.

This is a huge cause and effect, which will provoke a war between countless worlds of the two tributaries. I don't know how many years it will last, and I don't know how many lives will die.

Don't worry about other things first. First of all, their workload will definitely double again.

Because a large number of lives died, the workload for them will also double. The old man said it several times, but he didn't say it.

Think about it carefully, I can't control this matter. The long river of time is guarded by the predecessor. He can do whatever he wants. No matter what he does, he must have his reasons.

The senior himself must have known that breaking the boundary wall would bring war to many worlds.

So, the senior must have his own reasons.

Thinking of this, he also shut his mouth honestly.

"How far is it?" Su Mu asked after breaking the stone dam and entering the new tributary.

"We'll be there soon." The old man replied.

In fact, for Su Mu, it is also his own standard, and he has his own pros and cons.

Logically speaking, he would definitely not take the initiative to destroy the dam of the river, but... Instead of taking a detour, it is better to destroy the dam first, repair the stone bridge as soon as possible, and then come back to repair the dam again, so as to maximize efficiency and benefits.

[Congratulations to the host, maintaining the stability and stability of the river, favor points +20,000]

Half an hour later, the new stone bridge was repaired, and another 20,000 favor points were credited!

When returning by the original route, Su Mu was also preparing to repair the dam he had just broken.

But after thinking about it carefully, there is no favor point to be gained by repairing it, and it will waste time.

Because the system has learned to be smart, in order to prevent bugs, if you repair something that you have destroyed yourself, you will not get any favor point reward.

Moreover, in fact, it does not matter if this dam is gone, because these two tributaries are adjacent to each other and are of similar size. After opening it, it will not cause any flooding.

It is getting dark.

Su Mu repaired ten stone bridges in total, and it took only one day to complete all the workload of the old man's maintenance task!

The old man was so happy. If it weren't for the huge gap in status, he would have wanted to recognize Su Mu as his adoptive father.

He didn't know how to repay this huge favor.

What the old man didn't know was that Su Mu himself was the happiest. He earned 200,000 favor points in one day, and his mouth couldn't be suppressed.

Seeing that it was getting dark, the old man also asked tentatively: "Senior, it will be dark soon, why don't you go to my place to rest for a night?"

Hearing this, Su Mu was stunned and asked: "Is your home nearby?"

"Yes, what a coincidence, one of my mansions is just nearby, more than ten minutes away." The old man replied with a smile.

Su Mu thought about it, nodded and said: "Okay."

Because Su Mu's current location is very far away from his stone house, even if he rushes back, it will be dawn.

After all, Nannan is not alone at home now.

Before leaving, he asked the little fox to go home. With the little fox, the old blue cow, and the willow tree at home, Nannan's safety is guaranteed and nothing will go wrong.

After hearing Su Mu's answer, the old man's mouth was about to burst from laughing.

"Xiao Niu, Xiao Ma, you two take the helm and go home."

"Okay!"

"Senior, please sit down and take a rest. It's time for a cup of tea."

The old man picked up a pot of tea on the table and refilled Su Mu's cup.
