In order to achieve Xia Fan's goal of integrating the heavens and all worlds, a large part of the roots of the Tongtian Tree, which had been deeply rooted in the land of the ancestors, began to continue to grow, extended, passed through a long distance, and even the vast void, and then penetrated into one world after another.

Although the previous Babel Tree was also claimed to be rooted in the land of the ancestors and connected the heavens and all worlds, it was somewhat nominal, and it was true that it was rooted in the land of the ancestors, but there were not too many worlds connected by the roots.

Even if there were, it was a vast world like the Xuankong Realm that was relatively close to the Immortal Realm.

As for the farther things, the roots of the Babel Tree never touched.

At this time, Xia Fan changed the way of the Babel Tree in the past, and the roots spread out, like an octopus that was extremely greedy and wanted to collect everything, and began to hook up any world in the void.

Xia Fan didn't care whether these worlds were big or small, let alone rich or barren, as long as it was a world, he would stretch out the roots of the Babel Tree and then take root.

Xia Fan did this, of course, not to be hungry and eat to the point that he would pull into his arms regardless of whether it was good or bad, but he understood that there is no completely useless world in the world, as long as it is used well, even waste can be turned into treasure, and it is a world.

When the roots are rooted in the world, the Babel Tree can not only control it completely, but also gain various benefits from it, such as the power of the world and the rules of the world.

Of course, the Babel Tree is not a blind request, but will also give back benefits to the world in which it is rooted.

There are two obvious benefits, one is that no matter which world has the roots of the Babel Tree, the aura of heaven and earth will become much richer and purer than before.

This meant that there were only cultivators in that world, and the speed of cultivation would inevitably be much higher than before.

Second, the roots of the Batentree are like a passage that connects the world to the rest of the world.

For cultivators who originally lived in some small worlds, this was definitely a great benefit, because in the past, after they had cultivated to a certain level, they might not be able to break through again because they had exceeded the world's tolerance limit.

But now, after breaking through the original limit of strength, he can enter a higher world to continue his cultivation and move up step by step.

Although such a process is still difficult and dangerous, it is undeniable that for cultivators living in the Nether Realm, this is already a dream opportunity.

No matter how difficult and bumpy the road ahead is, even if it is full of hardships, it is definitely much better than no road at all.

It is precisely with such a road that can continue to go up and eventually reach the immortal realm that almost in a fairly short period of time, a group of strong people have emerged in various worlds of all sizes that have been rooted by the Tongtian Tree.

Their overall strength is actually not strong, and some of them can't even beat the Grandmaster Realm, let alone the Dao Realm.

However, they will enter a higher world to continue their cultivation, and their strength will continue to rise. Until finally ascending to the immortal realm or falling for various reasons.

Such a process is not cruel or not, but survival of the fittest.

However, for Xia Fan, it has a considerable advantage, that is, he can at least be sure that in the next four or five hundred years, there will be a large number of Dao Realm powerhouses entering the immortal realm and becoming the main force on the battlefield in the future to fight against evil cultivators.

This is also the purpose of Xia Fan using the Tongtian Tree to connect these worlds and open the way to the immortal world for them.

At first glance, Xia Fan was quite cruel and ruthless, but in fact, this was the most normal thing. If you want to win a war, it is useless to rely on your pulse and affection, and besides, this world is not his own world, if you want to protect this world, you naturally have to help everyone.

In the beginning, Xia Fan only let the roots of the Babel Tree hook up the world controlled by the cultivators. First there was the ownerless world, and then even the world with the lord was no longer spared.

Of course, the current Xia Fan doesn't look down on the worlds in the hands of others, and he won't use this way to rob other people's things, what he has to do at this time is more like requisitioning, because he needs to call on all the resources he can, just to deal with the cruel war that was blocked by the Immortal Emperor.

Later, when the worlds belonging to the cultivators had been connected by the roots of the Babel Tree, Xia Fan looked at the worlds that were controlled by the evil cultivators.

Such a process could not be gentle, and conquest and killing were indispensable.

At the beginning, Xia Fan directly controlled the roots of the Babel Tree, and when it was implanted in the world to be conquered, it would wipe out all the alien races that were loyal to the evil cultivators.

Later, Xia Fan found that this was really troublesome, and it would not be of much benefit to himself and the future war.

So Xia Fan then changed his strategy, first issuing a summoning order through the roots of the Babel Tree like the cultivators of the worlds that had been linked before, and then using the roots of the Babel Tree as a channel to transport troops, sending them to the worlds owned by the evil cultivators, and guiding the cultivators to complete the conquest of these worlds.

Such a process will inevitably lead to many cultivators being killed and injured in battle, but it will also hone them stronger. And this is precisely Xia Fan's purpose.

Of course, the evil cultivators were not willing to let the world under their control be constantly snatched away, so they would naturally try their best to fight back, but in this kind of war for the world, it was really difficult for them to become Xia Fan's opponents.

After all, even if Xia Fan was high up in the immortal realm at this time, he could use the Tongtian Tree to connect any world that was rooted, and then call all the cultivators who were willing to be used by him.

In this way, whether it is a local battle or a full-scale war, Xia Fan's side has taken advantage of it.

Especially for the ultra-long-range attack across many star fields, Xia Fan's side took advantage of it. Because no matter how fast the Void Airship is, it can't be as fast as the roots of the Babel Tree can travel through the void.

And as long as the roots of the Babel Tree can be extended to the point, then Xia Fan can throw a large number of soldiers and horses over at any time. If one batch fails, two more batches will come, and they will not give up until they form a crushing trend in terms of troops.

The consequence of this is that no matter when, where, and under what circumstances a war starts, Xia Fan's side can always have a considerable advantage in numbers.

There may be many ways to war, but in the final analysis, it is inseparable from the two warring sides, and if you want to win a war without considering logistics, the more troops you have, the more you will definitely take advantage of.

The evil cultivators of the lower world were defeated and retreated, and they suffered heavy casualties, so they naturally wanted to ask for help from the upper world.

However, in this kind of war at the bottom, too strong will become an obstacle.

The reason is very simple, for example, if a middle thousand world goes to war, not to mention the number of soldiers and horses on both sides, most of the strongest force is also the god realm, and there is not even a strong person in the early stage of the grandmaster realm, otherwise, the middle thousand world where it is not good will have collapsed directly because it can't bear it.

The world to be fought for has collapsed, and then in the end, who wins and loses in the war will naturally be meaningless.

This is just the Grandmaster Realm, and if it is replaced by the Ask Dao Realm, it is even more needless to say. Some of the worlds that are a little worse may not be able to withstand the great power of their bodies.

Because of this restriction, the upper realm has never directly participated in the wars of the lower realm, first, it can't afford to lose this person, and second, it is unnecessary.

Now that the evil cultivators of the lower world have been beaten so badly, especially the territory of the lower world has been taken away in large quantities, the evil cultivators of the upper world are naturally a little unable to sit still.

After all, without the territory, there would be no continuous transportation of soldiers and horses, and it would be impossible to win this war involving the heavens and all the worlds by relying on the powerhouses of the highest realm alone.

As a result, there were constantly evil cultivators from the upper realm who continued to descend to the lower world, even if they suppressed their own strength, they had to participate in the war, so as to reverse the current declining war situation.

If they were only facing cultivators from the bottom world, and they were bullying the weak with the big and the small, they would definitely win.

It's just that they didn't know that they were facing a powerhouse like Xia Fan. In the matter of bullying the small with the big and bullying the weak, Xia Fan did even more excessively than them.

In this way, the evil cultivators who originally wanted to suppress their own strength to secretly help were miserable.

Of course, Xia Fan would not take action personally, because he really couldn't afford to lose this person, but he could send more powerful cultivators to participate in the war in the lower world.

His goal has always been simple and clear, that is, to win a complete victory in the war of the lower worlds no matter what.

In the past, Xia Fan did not have a particularly clear understanding of the structure of this heaven and earth, and it was not until he began to use the Babel Tree to connect the heavens and all worlds that he gradually had an overall understanding, and then he had such a strategic layout.

The reason why he did this was because he found that from the highest immortal realm, to the Xuankong realm at the next level, and then to the starry world at the bottom, it was a pyramid-like structure from top to bottom.

It's just that the pyramid is only halfway, as if it has been cut by a knife.

Cultivators accounted for half of it, and the other half was naturally occupied by evil cultivators.

Not only is the territory of the two sides clearly divided, but there is even a strong void turbulence between the two, and the reason for this situation is naturally related to the war back then.

In order to keep the evil cultivators out, I don't know how many Emperor Realm cultivators have paid with their lives for this.

With the dividing line formed by this layer of void turbulence, it is not easy for the two sides to go to war.

Because there are not many places where the two sides can come into contact, only two.

One is the highest place, that is, the passage behind the door that the Immortal Emperor has sealed.

The other place is the lowest world, because the void turbulence back then did not completely tear this heaven and earth in half, and the bottom layer was still connected together.

At the same time, due to the passage of time, the Void Turbulence has gradually weakened, so it has become easy to connect between the underworlds.

It is precisely for this reason that the war between the Xuankong Realm and the Evil Heaven Realm has always been dominated by the competition of the lower world.

Xia Fan wants to snatch the bottom world of the evil cultivator, and his idea is to continuously annex the territory of the evil cultivator from the bottom up. This move is definitely a killer move from the bottom of the kettle.

Don't look at the fact that there are no strong people in the lower world, but there is an incalculable population, which can provide a steady stream of soldiers to support the endless wars of the evil cultivators.

Without these, the forces of the cult cultivators would only dwindle and dwindle until they were finally completely finished.
