It was only half an hour after Xu Yu disappeared from the exit passage that the local torrential rain gradually subsided. 【】

Then, after dozens of breaths, the eroded space-time gate that had been eroded and riddled with holes gradually returned to leveling, and a figure escaped from the outside.

After stepping on the void full of corrosive power inside the Holy Land, the figure laughed dumbly, "I didn't expect that at my age, I would have to act as a bodyguard for a little guy in secret." ”

This figure is the previous Ji Ying, with his status on Mie Island, he is naturally qualified to know the meaning of the three ancestors, although Sanxian Island values Xu Yu very much, but he will not do everything for him, even if he is a genius, he needs to be sharpened to truly grow into a towering tree.

However, in the grinding, he is not afraid of 10,000, just in case, in case Xu Yu encounters a force majeure accident, it will be a great loss, and this time he received the order to secretly follow Xu Yu to the Holy Land.

This kind of covert protection must not let Xu Yu know, but it must also be guaranteed that once the other party encounters a force majeure accident, he can arrive in the shortest possible time.

This point is really not a big problem for Ji Ying, because the three ancestors of Sanxian Island have already placed secret techniques in Xu Yu's body, according to some special methods, as long as Xu Yu is not more than half a light year away from Ji Ying, he can clearly perceive the strength and direction of his life breath.

And as a Four Tribulations Scattered Immortal, Ji Ying's speed is also extremely terrifying, once he casts the strongest escape technique, he almost reaches fifty times the speed of light, with such a monk's tail line protection, even if he is extremely far away from Xu Yu, far beyond the range that his cultivation can perceive, but as long as he relies on the secret treasure in his hand to sense the strength of Xu Yu's life breath, it is enough.

After all, this is a holy place, far more dangerous and complicated than the alien beast space.

The next moment, Ji Ying took out a green jade plate from the storage ring, and this green jade plate exuded vitality.

That is the treasure that can sense the strength and direction of Xu Yu's vitality.

After a little induction, Ji Yingcai put away the jade card again, and chased after Xu Yu in the direction where he left, he didn't want to protect Xu Yu closely, he kept watching the other party's every move, in this regard, he was really afraid that Xu Yu would find him, after all, that guy is a super genius who has not been met in ten thousand years, who knows if there is a special induction method?

If the other party finds out that he is secretly investigating and protecting, then after the other party has no worries, the meaning of tempering will become weak, so this kind of tracking, Ji Ying will not find out what Xu Yu is doing, as long as he can know that the other party's vitality has always existed, and can guarantee that in case of an accident, he will rush over in the shortest possible time.

In fact, it was not only the Mie Island that would exert such strict protection on Xu Yu, but also some particularly important monks in the other three major forces would also have similar treatment.

........................

Two days later.

In the depths of the holy land, as a streamer of light swept by, Xu Yu's figure appeared directly in a low mountain forest.

During the two days of escape, most of the time was traveling at the speed of light, and Xu Yu at this time was really far away from the entrance.

In the past two days, according to the route shown on the fifth-level map, he picked a relatively remote road, and Xu Yu encountered a torrential rain and two hurricanes along the way, but he didn't even encounter a wandering dark beast, which was really very lucky.

However, this is also thanks to the huge functionality of the level 5 map.

This fifth-level map explored by the Seven Tribulation Scattered Immortals is not only huge in scope, but also the most important special surname is exhaustive.

Starting from the entrance and exploring in all directions, among the countless roads, where is the area where dark beasts often haunt, where is the route that dark beasts are least likely to infest, where is prone to wind tides, where is prone to rainfall, etc., are clearly marked.

As for those murderous places that are more dangerous than dark beasts or wind, rain, thunder and lightning, etc., they are also very clearly marked, and among these fierce places, there are even more clear grade markings, plus the details inside.

The first-level murderous land is enough to destroy the Void in the early stage of the eightfold tribulation, or the area where the immortals are scattered in one calamity.

The second-level murderous land is the area that is enough to destroy the Void Void Stage, the Eightfold Tribulation, or the Second Tribulation Scattered Immortals.

......

And so on, this fifth-level map is really too helpful to Xu Yu, and what he got from Triple Island is not only this fifth-level map, but also a kind of treasure that can sense the Heavenly Cultivation Stone, the Dark Repair Disk.

The appearance of the dark repair disk is only the size of a palm, but it can change in the air, and its shape is similar to that of a compass.

This kind of treasure of induction cultivation stones, almost all the monks who enter and leave the holy land have one copy, but each person has a different power of the treasure.

Taking the dark cultivation disk in Xu Yu's hand as an example, up and down in his vicinity, left and right, within an hour of the speed of light, as long as there is a Heaven Cultivation Stone, it can be clearly sensed.

This kind of range is definitely one of the top induction magic weapons, and its preciousness is not inferior to the level 5 map in his hand.

However, in the past two days, in the past two days, in the escape along the safe route, the dark repair disk in Xu Yu's hand has never moved in the slightest.

"This route is also hidden in the fifth-level map, but there is still no existence of the slightest Heavenly Cultivation Stone, it seems that it is definitely not easy to gain something in the Holy Land. ”

Stopping in the mountains and forests, Xu Yu's face breathed a sigh of relief, the route he was traveling on now was definitely an extremely hidden place, during which he had to pass through three or four fierce places, and he had to pass by the edge of a third-level fierce land, and it was impossible for ordinary monks to find out.

Only when he confirmed that it was safe did he dare to try to fuse the corrosive gases around him.

The next moment, Xu Yu summoned out the fifth-rank aura and tentatively fused to the left and right.

This matter can't be delayed any longer, you must know that there are only 22 Dark Cloud Pills on his body, and now he has wasted two.

After the surging fifth-rank aura quickly invaded to the left and right, the corrosive air around it, which was originally silent and waveless, instantly changed as if it had no shortage of qi and no qi before.

Can be fused!

As soon as he realized that he could fuse, Xu Yu's face showed a hint of ecstasy.

Even if he had long thought that according to his previous experience, the chance that this corrosive gas could be fused by him was extremely high, but when this really happened, it still made him very happy.

Because this not only allowed him to find a way to replace the Dark Cloud Pill, but also meant that from now on, he had one more means of attack, and after this corrosive surname gas was concentrated to a thousand times, or even thousands of times, its attack and killing strength was also terrifying.

Next, Xu Yu began to merge without hesitation.

Although he didn't plan to fuse the Dark Cloud Pill Qi on his body all the time here, even if it was only fused for three or four days, the corrosive gas he could store was enough to make people fearful.

Time passed gradually in silence, and three or four days passed in a flash, and the corrosive gas that was fused in Xu Yu's hands was also so thick that it was outrageous.

However, it was also in this fusion that he discovered another problem, that is, with his current potency, he could also concentrate these gases to a thousand times at most.

This compression of corrosive gases is more difficult than not running out of gas and not retaining gas.

There was no shortage of gas at the beginning, and it could be compressed to four or five thousand times as large under his compression, and four or five thousand parts of gas were compressed into one part, and its instantaneous burst of attack power was definitely jaw-dropping.

But this corrosive gas, even if he tried his best, could only compress it to a thousand times.

However, even if it is a thousand-fold attack, it can definitely support the horror, Xu Yu even took out an experiment of a low-grade immortal weapon refined by four-colored stones, and the result of this experiment was that the lower-grade immortal weapon was instantly turned into ashes under the attack of a thousand-fold concentrated corrosive gas.

Even if it is a medium-grade immortal weapon, it can't withstand a few breaths, and it is corroded into nothingness.

As for the high-grade immortal weapon, he didn't have many of his own, so Xu Yu stopped the experiment, but even if it was a high-grade immortal weapon, I am afraid it would be difficult to resist the invasion of this thing, and I am afraid that it would be corroded into slag in a moment.

In particular, although he can only compress this thing to a thousand times, it is better than the quantity.

After being refined, the corrosive gas can not only be used as a sword or armor, but can also change at will according to his mind, even if it is a net, mist, or a small-scale and overwhelming range attack.

Of course, its use also needs to be supported by Xu Yu's cultivation, with his current ability, if he casts a thousand-fold attack at the same time, and it is a range attack, then he can attack ten targets a thousandfold at most.

But even if you can only attack ten targets at the same time a thousandfold, it is an extremely terrifying thing.

If you turn these ten targets into one, it is almost ten thousand-fold attacks that fall at the same time, although there is still a gap between that and 10,000-fold attacks.

The real 10,000-fold attack is a 10,000-fold attack that falls on one point at the same time, and the 1000-fold attack is to fall on the same target at ten different landing points, such as scattered in the hands, feet, limbs, etc., the power will seem to be much dispersed, but it is also much stronger than a single thousand-fold attack.

If he used ten thousand-fold attacks at the same time, Xu Yu was confident that even a medium-grade immortal weapon could be corroded instantly.

"This thing doesn't have a name yet, it comes from the Holy Land, and the biggest special surname is Corrosion, so it's better to call it Holy Rot. Waving his hand to put away the holy rotten qi in his hand, Xu Yu escaped from the spot with a chuckle.

This time he came to the Holy Land, just the harvest of this Holy Rotten Qi was enough to satisfy him.

This thing is not weaker than the high-grade golden thunder to some extent, maybe in terms of individual lethality, the holy rot qi is not as good as the high-grade golden thunder, but on the whole it is more practical than the golden thunder, because the golden thunder needs to be conceived, and the consumption of him is even greater, but the holy rot qi is inexhaustible for him, and it can be used for a long time with a reserve, although there is also an upper limit of attack when it is cast, at most it is a thousand-fold attack, but the consumption of his own power is not large!!

"With the Holy Rotten Qi, it's time to look for the Lower Cultivation Heavenly Stone. Next, Xu Yu suddenly took out the dark repair disk and went straight into the sky.

With his current strength, he can almost compete with the Three Tribulation Scattered Immortals, and with the help of the fifth-level map and the Heaven Cultivation Stone, it is not impossible to find the Heaven Cultivation Stone for the rest of the time.
