Before Liu Yuan entered the secret stronghold of this human race, he erased all traces of his activities around him, and after hiding it, he entered it.

Before, Liu Yuan had already exhausted the cultivation time of today's sentient beings and martial arts cultivation centers in the "Qingyuan Tribe", so now Liu Yuan could not enter the martial arts training center to conduct experiments in this area.

Liu Yuan first looked at the environment of this secret stronghold, and found that this place was exactly the same material as the stone crevice space that Liu Yuan had found around the lake before.

This kind of stone can isolate the perception from the outside, and hide the breath and energy body in the space.

Although this kind of material can be quickly manufactured by the Human Federation on the Dragon Star, this kind of thing can be said to be chicken ribs on the Dragon Star.

Because, the reason why this material can isolate perception from the outside is only for the creatures in the Strange Rainforest, which is nothing at all for Liu Yuan.

Because the creatures in the entire Strange Rainforest have very weak soul power, which directly leads to their very weak perception power, and some spies can only meet the requirements of intelligence detection through some special equipment.

These special materials that can isolate the perception of most creatures in the Rainforest, coupled with the fact that Liu Yuan has not entered the system sentient beings realm or the martial arts cultivation center to cultivate, can consciously hide the aura and energy fluctuations emanating from his body.

Therefore, this secret stronghold can basically meet Liu Yuan's needs to hide himself, and officially became a temporary stronghold for Liu Yuan's cultivation.

The soul martial art Huangquan Ferry: Volcanic Hell was instantly displayed by Liu Yuan, but this time the soul martial art was limited by Liu Yuan, and the Flame River and the Volcanic Hell Ferryman and so on were infinitely reduced.

After reducing a large amount of energy consumption, Liu Yuan gradually adapted to the state of using the soul martial art Huangquan Ferry: Volcanic Hell, and immediately began to prepare to try a general slash.

Liu Yuan slowly pulled out the soul blade Ming Hong in the sword mound on his waist, and slashed out a knife in front of him, the power of this knife was probably barely reaching the level of the junior title god of war.

But it was such a very simple slash, and the moment it was unleashed by Liu Yuan, it almost interrupted Liu Yuan's soul martial art, Huangquan Ferry, Volcano Hell.

Liu Yuan had never used the Soul Martial Technique Huangquan Ferry: Volcano Hell in the middle of the process, and there would be such a feeling of wanting to interrupt.

Because of Liu Yuan's soul martial art Huangquan Ferry, Volcano Hell, since Liu Yuan exchanged it in the system mall, one of them was used as a means for Liu Yuan to press the bottom of the box.

Moreover, although Liu Yuan has not believed in the system all along, the martial arts or evolution techniques obtained from the system, Liu Yuan has tried his best to cultivate through his own efforts.

However, whether it was exchanged by Liu Yuan through the system mall, or smelted through the Wanfa Furnace, or drawn through the lottery, there was no major problem in the system.

And today, all of a sudden, this kind of problem occurred in the Soul Martial Technique Huangquan Ferry, Volcano Hell, which still made Liu Yuan understand that in fact, the system is not omnipotent.

However, at least the slash that Liu Yuan slashed out just now was successful, and the same soul martial art Huangquan Ferry: Volcanic Hell was also controlled by Liu Yuan without interruption.

This is also a very good start, if Liu Yuan was interrupted at the beginning before he could slash out that soul martial art, Huangquan Ferry, Volcano Hell, then it proved that Liu Yuan's idea was not feasible.

And Liu Yuan slashed out this knife, and the soul martial art Huangquan Ferry, Volcano Hell was not interrupted, which shows that Liu Yuan can actually carry out this offensive technique through training.

As long as the time and amount of training were reached, Liu Yuan believed that he would definitely be able to use the soul martial art Huangquan Ferry: Volcanic Hell while engaging in melee confrontation with other enemies at the same time.

Immediately, Liu Yuan was directly immersed in this training, and only in this training and cultivation that could improve his strength could Liu Yuan really sink his mind into it.

Just when Liu Yuan was cultivating, within the ten major cities of the Terran Race, the top powerhouse of the Terran had already brought the "Green Dragon" and "Xuanwu" and the remaining Terran soldiers back to the Terran territory.

Among the ten major cities, "Chishan City" was surrounded by the remaining nine Terran cities, and all the Terran combat power was transferred to these nine big cities around "Chishan City".

Except for the entire human race, which appeared at this level of alertness in the war with the Zerg a long time ago, only today has appeared.

Basically, ninety percent of the Terran tribes that could rush to the ten major cities of the Terran tribe arrived, and the non-combat units were concentrated in the "Red Mountain City".

Although the population density of the entire "Red Mountain City" is very large now, there is no way to do it, but fortunately, the materials stored here can support the human race for a period of time.

And it is unlikely that the invading tribes of the Terrans will besiege the Terrans for a long time, not to mention whether the base camps of these races will be attacked by surprise.

It is impossible for Liu Yuan to let the various races encircle the human race for such a long time, once Liu Yuan has mastered the soul martial art Huangquan Ferry, Volcano Hell, and at the same time to carry out the battle at the same time.

The first race to be destroyed is the Zerg, and when the time comes, there is no need for the Terrans to launch a counteroffensive, and the tribes of the Terrans who come to besiege the Terrans in the Rainforest will withdraw their troops.

At that time, Liu Yuan's threatening power was already the largest in the entire Strange Rainforest, and almost all creatures had no way to threaten Liu Yuan.

One after another war equipment was transported by the Terran from the major fronts to the surroundings of the Ten Cities of the Terrans, and the soldiers of the Terran almost destroyed the entire Ten Cities of the Terrans.

One of the reasons why the entire human race was able to survive in the space of the Rainforest for such a long time was because the cultivation talent of the human race was very high, and there were many strong people born, who could confront all races in terms of high-level combat power.

The reason for the second song is because the Terrans have something that other races in the Rainforest do not have, that is, the extremely high ability to make tools through wisdom.

Just like Hao in the "Qingyuan Tribe" a long time ago, the poisoned arrow used to knock down the third prince of the Centaur clan is a very vivid embodiment.

At that time, the "Qingyuan Tribe" was just a very ordinary small human tribe, and the strongest person was only Hao, who had cultivated to the level of a sixth-layer hunter.

Not to mention the ten major cities of the Terran that represent the highest level of development of the entire human race, and the power of each of the war instruments made here, some of the war equipment, is comparable to the war machines made by the Human Federation on the Dragon Star.

At this time, the Terrans were almost always in a state of full alert, although these people had already adapted to the environment of the Terran Rainforest, which was full of literature, before migrating from all over the Terran territory to the Ten Great Cities of the Terrans.

However, this time the battle was too big, and basically some Terran powerhouses who had cultivated to the seventh level of hunters that they had never seen in their lifetime could be seen at any time in the Ten Great Cities.

Only Song, the oldest Terran top powerhouse, has experienced two of the largest wars of the Terran, and both of them are against most of the races in the entire Terranic Rainforest.

Standing on the walls of the "Lava City" among the ten major cities, Song actually showed a faint smile on the corner of his mouth, looking at the Terran soldiers around him who were busy and couldn't find their heads, and gradually began to recall the war a long time ago.

Looking at the Terran soldiers holding a box of supplies beside him, Song seemed to think of the old guy who grew up with him a long time ago, and became a powerful Terran soldier together, and finally became one of the top powerhouses of the Terran Race.

It's just that in that battle, in order to cover Song's retreat, this old guy was buried in the hands of a top powerhouse of the Zerg.

If you talk about the entire human race, who has the strongest hatred for the Zerg, it still depends on Song, the top powerhouse of the human race.

Because Songke personally experienced the war that brought down the Terrans, and watched his relatives and friends die in front of him, and the current Terrans have hatred through repeated conflicts between the Terrans and the Zerg.

The content of that war was passed down from generation to generation and conveyed to them in the form of stories, so the hatred of the other Terrans towards the Zerg was the same as the same as the races in the Rainforest that were also directed against the Terrans.

In fact, Liu Yuan's plan to directly select the target to attack as quickly as possible was not very agreed, but Song agreed and persuaded his apprentice very easily, coupled with Yuan's militant on the side, he agreed to cooperate with Liu Yuan.

In fact, there is still Song's selfishness in this, when Liu Yuan proposed that he would quickly attack a peak race, in fact, Song's heart has always hoped that Liu Yuan would choose the Zerg.

Moreover, Song's intention to hand over the "Tianyan Documentary" to Liu Yuan was also very simple, because Song guessed that Liu Yuan should not be a native of the space of the Rainforest.

Otherwise, Liu Yuan, a super strong person of the human race, would have been discovered a long time ago and secretly protected, and when the human race developed to the right time, Liu Yuan would appear and exert the greatest effect.

Therefore, Liu Yuan is very likely not to understand the history of the entire Strange Rainforest, and Liu Yuan revealed his identity as a human race to Song, so Song immediately thought of this method.

handed over the paper book "Tianyan Documentary" to Liu Yuan, just to let Liu Yuan understand the history of the human race a long time ago, and then vaguely guide Liu Yuan's attention to the Zerg.

Moreover, Song is not worried at all that Liu Yuan will not be able to read this "Tianyan Documentary", if you want to say Liu Yuan's "Taoism" language, it is even more fluent than Song's speaking, and there are some more obscure words that Liu Yuan can recognize.

Sure enough, in the end, Liu Yuan's chosen target was the Zerg, and Song just wanted to arouse Liu Yuan's common sense of honor as a human race, and wanted and supported the emotions of the human race.

This is not groundless, when Song and Yuan rushed to the "Qingyuan Tribe" with a team of human races, only the human race was qualified to enter in advance, and from this incident, Song knew that Liu Yuan actually had feelings for the human race.

In fact, these things that Song did had already been understood from the time Liu Yuan knew that Song was the oldest Terran top powerhouse, even if Song didn't do these things, Liu Yuan would also choose the Zerg as the first target.

One reason is that the Zerg can be said to be among the top three in the threat level in the entire Terrified Rainforest, and has a large number of low-level and middle-level Zerg warriors, and the Zerg's powerful violent ability is very unfavorable to Liu Yuan's plan in the later stage.

The second reason is because Liu Yuan looked at this Zerg in the Strange Rainforest, just like he was watching the Fog Realm Mist Beast fighting against the Human Federation on the Dragon Planet.

It can be said that in the entire Strange Rainforest, the things that Liu Yuan hates, in addition to the totemic power that represents the power of the evil gods, are the Zerg that are very similar to the fog beasts of the fog realm.

Song stood on top of the city wall and watched as an ordinary Terran soldier who had not rested because he had been carrying heavy loads for a long time, and he was about to lose his bearing.

Now in the entire ten major cities of the human race, there are countless people who have no strength, but still contribute to the human race, and just as he was about to press the book, he was pulled up by the powerful energy emitted from Song's body.

Song directly took the box in the hand of the Terran warrior, and said to him with a smile:

"Kid, you're tired, go get some rest and come back later."

This ordinary warrior of the Terran race, who almost fell to the ground, didn't know that it came from that remote small tribe of the Terran race, and the top powerhouses of the eighth layer hunter level such as Song were god-like existences in their eyes.

After Song sent him away, he put the box in his hand where it should be, and as soon as he put it down, Song received a message from his apprentice Cang.

"Master, which thing Shura gave me is indeed very effective for Yi, and Yi's injuries are almost healed."

Looking at this information, even if he is old and steady, he can't control the smile on his face, one good thing happens in the Terran, and the cohesion of the Terran regardless of its strength, which is a sign of the imminent revival of the Terran.

Before, Liu Yuan heard the news about the disappearance and injury of Yi, the top powerhouse of the human race, from the old man of the "Qingyuan Tribe", and when Liu Yuan handed it to Song and Cang to concentrate the flame crystals, he also gave Cang a bottle of high-grade energy liquid.

Moreover, he deliberately told Cang that this was for Yi to heal his wounds, because Liu Yuan was not like the human race lacked the combat power of Yi, a top powerhouse, and Yi's combat power was only second only to Cang in the entire human race.

Originally, Liu Yuan had been using high-grade energy liquid for cultivation before, which was a kind of material for Liu Yuan's regular replenishment of energy and cultivation.

And when Liu Yuan entered the Strange Realm Rainforest, he found that in fact, these powerful creatures in the entire Strange Realm Rainforest were very, very slow to heal, and they were not as strong as the Human Federation on the Dragon Planet.

Soon, Liu Yuan understood the reason, that is, because all the creatures in the Strange Rainforest contained too little energy, and the reason why they had such a strong strength was because their control of energy was very terrifying.

The environment of the Rainforest is filled with an extremely high concentration of "Yin and Yang" energy, although the level of this energy is very high, but even Liu Yuan's strength will take a certain amount of time and energy to digest and absorb it.

Therefore, it is also not a very efficient way to let them recover their injuries by absorbing "yin and yang" energy, and Liu Yuan found that they want to heal their injuries quickly, all of which are facilitated by some special evolutionary plants.

And those evolutionary plants were not as good as the high concentration of "yin and yang" energy that filled him around him, and the reason why these evolved plants were able to help them heal quickly.

The essential reason is that because they can quickly replenish the energy consumed in their bodies, with the support of energy, the speed of natural recovery from injuries is much faster.

Therefore, Liu Yuan directly chose the high-grade energy liquid and handed it to Cang, and let Cang use it directly to Yi, which was definitely much better than most of the healing evolution plants in the Mysterious Rainforest.

The entire human race has made all the preparations for war, just waiting for the various races to come and attack, and Liu Ya on the side is still immersed in training.

Time passed very, very quickly, and the Zerg Empress Taj needed time to cultivate secret weapons, so she slightly delayed the time for the races to attack the Terrans.

And today, the cultivation time of Liu Yuan's system sentient beings realm and martial arts cultivation center has also been reset, Liu Yuan looked at the communication equipment that Cang handed over to him before, and there was no information coming over.

Liu Yuan prepared that as soon as the battle on the side of the ten major cities of the Terran started, he would directly kill the Zerg base camp, so as to ensure the feasibility of the plan to the greatest extent.

However, this time, Liu Yuan did not choose to enter the realm of sentient beings to cultivate first, but plunged directly into the martial arts training center, because Liu Yuan faintly felt that he could find a breakthrough point in the martial arts training center.

Before entering the martial arts training center, Liu Yuan added martial arts points to various martial arts, and looked at the information interface of the system by the way.
