Fengyun is in a dilemma, whether to stay and observe, or leave now, to join Shi Shan and the others, and go together to attack the cannibal barbarian army. Ｘ

If you choose the former, you can indeed understand the movements of some enemies, and at the same time, you can also have a grasp of the situation of the "time bomb" you have planted, and if you choose the latter, you can increase the chance of success in sneaking up on the cannibal barbarians, in addition to increasing his own combat power, he can also command the Rock Worm King to assist everyone.

Fengyun didn't dwell on it for too long, and quickly made a choice, and he chose the latter.

Now the cannibal barbarians are focusing all their attention on attacking Rock City, and from the current situation, there will be no new changes for a while, and it is not worth continuing to observe.

As for the time bombs he planted, they were already like that anyway, and they were not even under his control anymore, so there was little point in staying.

Now it is very necessary to go to join up with Shi Shan and the others, in addition to the fact that the Rock Worm King can provide them with the opportunity to get close to the enemy at a critical moment, and surprise the enemy, but also because of the time bomb he planted, it is necessary for him to inform them.

Although he couldn't confirm how big the stones were that had built the underground route map of the Twin Cold Springs inside, he couldn't confirm how big they were, but judging by his intuition, it shouldn't be too small.

Although he hadn't made a special calculation before, in order to study the road map of the underground of the Shuangcold Spring, he once used a porcelain tube to do an experiment, and finally because the porcelain tube could not withstand it, it collapsed, and the destructive power that erupted scared him.

If he hadn't made a quick decision to send it into the sky, the consequences might have been unimaginable.

Compared with the porcelain tube used that time, the material used this time is undoubtedly much greater.

First of all, the stone is one, and the bearing capacity is much greater than that of the assembled porcelain tube, and secondly, the material of the stone is carefully selected by him, and it is quite excellent in terms of hardness and other aspects.

According to his estimates, even the smallest moment of stone explosion should not be less destructive than the time he experimented with porcelain tubes.

What's more, there are eight of them this time, and if it breaks out at once, the destructive power will not be as simple as one plus one, and it should increase exponentially.

As for the reason, it's very simple, the damage they cause is not only the shockwave generated when it erupts, but also the terrifying low temperatures that will occur in the area affected by the explosion.

Even if they become totem warriors, their body's resistance will be greatly improved, but this does not mean that they are no longer afraid of the cold.

Ordinary cold, such as the low temperature in winter, does not affect them much, and even some high-level totem warriors are not likely to be frostbitten if they are only wearing single clothes, but there is still a limit to their endurance.

Once they exceed their tolerance limit, they will be frostbitten or even frozen to death just like ordinary people.

If he hadn't been able to inform Stone Mountain in time, they would have found out that the defenders of Rock City were in a difficult situation and couldn't help but attack the enemy, and it was likely that they would be within range of the time bomb he had made.

By then, it will be too late.

Even if he rushed past the notification to them, it would be difficult to get them out of danger, because once he fought with the cannibal barbarians, he would fall into a stalemate, and wherever he wanted to get out, he could get out.

Besides, he wanted to let Shishan and everyone know about the danger, and he had to make a very loud noise so that the enemy would know about it.

Don't look at the cannibal barbarians and the Terrans as two different races, but since the two sides often fight each other, there is no lack of existence in which both sides know each other's language.

In other words, even if Fengyun used the language of the Terran to inform Shi Shan of them, someone from the cannibal barbarians would definitely know what he meant.

So, he had to stop them before they could do anything about the rocky mountain.

As for Rock City, he didn't need to worry too much, after all, he had already sent some reinforcements into the city through the passage dug by the Rock Worm King, and at the critical moment, they could completely go up to it.

Although the number of reinforcements entering Rock City is not too large to ensure that they can be inflicted heavy damage in the event of a sneak attack on the enemy, it should not be forgotten that they are a fresh force and are in very good shape.

This time, the cannibal barbarians attacked Rock City, although they adopted a wheel war, divided the people into several groups, and launched attacks in turn, striving for as much rest time as possible, but after all, they have been attacking for so many days, and their state has long been much worse than before, at least much worse than the group of Terran reinforcements who entered the city.

As long as the reinforcements can go up in time, it shouldn't be a big problem to resist the attack of the cannibal barbarians.

Besides, he didn't need the Rock City side to hold out for too long.

In order to avoid being discovered by the enemy, Fengyun dissolved the power of the totem that had banned the spinel power source by inputting the power of the totem when casting those time bombs, and it dissipated quite quickly.

If nothing else, they will be completely unsealed in the near future, and after they are unsealed, they should have reached the limit of those stones in a very short time.

You must know that in order to speed up the impact of the stone's bearing limit, he has already charged the inside of the stone before, which greatly shortens the time of the explosion.

After thinking about the benefits and losses, Fengyun was also a person of action, and immediately turned his choice into action, and rushed to the location of Shi Shan and the others.

"What's the situation?"

When Fengyun came to the place where Shi Shan and the others stayed, he couldn't help but be a little dumbfounded, there was no one left.

This is not to say that they have not stayed there in Stone Mountain, and what has been left from the ground is very urgent, and there are indeed a large number of people who have stayed there.

"Are they already ......?"

Fengyun's gaze moved on the traces left on the ground, trying to confirm where Shi Shan had gone, but before he could figure out a clue, a thought suddenly popped into his mind, which startled him.

Without thinking much about it, he raised his gaze, glanced around, and quickly locked on to a big tree and immediately rushed over.

In order to conceal their whereabouts, the hiding place chosen by Shi Shan and the others was a rather dense forest.

Without waiting to get close to the chosen tree, Fengyun jumped up and jumped directly to the height close to the canopy, and then grabbed a branch with his probe arm, swung it, flung it, and flipped it, and stood firmly on the branch.

The moment he stood firm, his eyes had turned into two golden vertical pupils, shooting out a sharp light, piercing through the gaps between the branches and leaves, and scanning in the direction of Rock City.

"It's fine. ”

After a moment, he breathed a sigh of relief,
