The old dragon

Soon, Su Huan's mental power was able to clearly perceive that the energy intensity contained in the Guixu Stone inside the sealed box had decreased, and guessed that the reagent had already produced an effect.

For the sake of safety, Su Huan first covered his whole body with the defensive ability of the fire guard ring, and opened the small opening of the airtight box.

After seeing that the power of returning to the ruins leaked out.

Only then can you open the sealed box with confidence.

I saw that the Guixu Stone had been wrapped in a mass of gray colloid.

The power of returning to the ruins has been wrapped in it and cannot be revealed.

Su Huan hurriedly dealt with the Guixu Stone.

After two or three hours.

The main medicine of the transformation secret medicine was finally prepared successfully.

[511.502, giant crystal rock dragon]

Su Huan sealed up the main medicine, leaving only the prodrug of the secret medicine, and summoned the crystal rock dragon to let him take it.

Su Huan naturally left his temporary laboratory and came to the open area outside the building to summon the crystal rock dragon.

After all, with the shape of a small hill like the crystal rock dragon, it is bigger than the house, and summoning it in the house can easily break the house from the inside.

The Crystal Rock Dragon stood by Su Huan and lowered his body, allowing Su Huan to pour a large bottle of transformation secret medicine precursor into its mouth.

Digesting the prodrug of Crystal Rock Dragon's metamorphosis secret medicine is not something that can be done in a short time.

According to the normal speed, it may take half a year or even longer.

Su Huan naturally couldn't wait so long.

If he had to wait for so long, it would be impossible for Su Huan to prepare the secret medicine for him to take now.

Crystal Rock Dragon's transformation secret medicine received the radiation of Guixu energy in the land of Guixu, and the speed of digestion and fusion increased dramatically.

Depending on the strength of the power of returning to the ruins, it is possible to increase it by several times to dozens of times or even hundreds of times.

In this Black Ruins City, there are not many things, but the power of returning to the Ruins is everywhere, and it is inexhaustible.

Naturally, Su Huan didn't need to worry about the crystal rock dragon's digestion of the prodrug of the secret medicine.

Even in a place like the garrison, where the power of returning to the ruins is very thin, Su Huan can feel that the speed at which the crystal rock dragon digests the prodrug of the secret medicine has increased several times.

Afterwards, Su Huan took the crystal rock dragon and walked towards the area with a higher concentration of Guixu power in the depths of Heixu city.

With the deepening of one person and one pet, the crystal rock dragon's digestion of the secret medicine began to increase.

Of course, no matter how fast the climb is, digestion is still a process, and it cannot be accomplished overnight.

Therefore, from the appearance point of view, it is still difficult to see the change of the crystal rock dragon.

The concentration of Angelica's power has reached the limit that the crystal rock dragon can bear without causing much damage to the body.

Su Huan stopped the crystal rock dragon.

This concentration has already exceeded Su Huan's own tolerance limit. Even if he activated the defensive ability of the Fire Guardian Ring along the way, he still felt a little uncomfortable under the shroud of the extremely suppressed aura of returning to the ruins.

After Su Huan instructed the crystal rock dragon to digest the secret medicine in this area, he left first.

A pet driver with a strong body can stay in this area for a long time, but a driver with a relatively weak body cannot.

Next, the crystal rock dragon stayed in that area, quietly waiting for the digestion of the secret medicine.

Crystal Rock Dragon also knows that he is becoming stronger step by step, which makes his heart full of excitement and anticipation.

Watching his companions surpass him in strength one by one, but he can only stay in the dangerous stage with the energy-absorbing tree that has never been keen on fighting, which has made Crystal Rock Dragon slightly depressed for a long time.

It must not let go of this opportunity to become stronger again.

In this area, the speed of the crystal rock dragon effect secret medicine has increased by about fifty times.

In terms of transformation time, it would take about four or five days.

For four or five days, Su Huan came to this area three to four times a day to check the transformation of the crystal rock dragon.

He clearly felt that the crystal rock dragon's physical condition was undergoing tremendous changes every day.

The biggest change is the change in the shape of the crystal rock dragon.

From the original body shape of more than ten meters long, it has continued to grow, 20 meters, 30 meters.

On the last day, it even turned into a real behemoth more than ten meters high and over 30 meters long.

Even if the more than 30-meter-long crystal rock dragon is crawling there, it looks like a hill, which makes people daunting.

The strength of the breath in his body has far surpassed that of the dangerous species.

Even Su Huan, who was standing not far from the crystal rock dragon, looked at his pet controler, and felt that the crystal rock dragon's aura was even more powerful than the advanced terrifying wind and thunder dragon that had already reached the end of its growth and was approaching maturity. above the snake.

This shocked Su Huan.

The strength of the Crystal Rock Dragon after transforming into the Yanxu Dragon can already be seen from here.

"Aww~" Crystal Rock Dragon prostrated lazily on the ground, calling out to its master.

To put it bluntly, this time becoming stronger is the most comfortable and relaxing time it has ever been.

I don't want to do anything, just lie down in a place where the power of Guixu is strong, and the secret medicine in my body will be continuously digested and fused to push my power to a higher peak.

This made the crystal rock dragon very happy.

The last few days have been in a good mood.

Su Huan stroked the crystal rock dragon Qi and felt the huge claws of the crystal rock dragon that were almost as high as his chest, and said with a smile: "After today, the pre-drug of the secret medicine should be digested, and then you can recover , we will start taking the main medicine of transformation and start the dragon transformation ceremony."

"Aww~hou~" Crystal Rock Dragon became anxious when he heard that Su Huan asked him to recover first before proceeding to the next step to become stronger, and quickly said that his condition was too good and he didn't need to recover.

Su Huan couldn't help laughing, looking at the anxious behemoth, he said: "If you feel that you are in good condition, then we will start to transform immediately after you digest the secret medicine."

Su Huan could also feel that there was nothing to recover from the crystal rock dragon's state.

These days he was lying down, and as the metamorphosis progressed, after the endurance of the power of returning to the ruins increased, he moved to a place where the concentration of the returning to the ruins was higher and continued to lie down.

After accompanying the crystal rock dragon for a while, Su Huan left first.

The power of returning to the ruins cannot be easily endured by a human body of flesh and blood, even with the protection of the fire guard ring, it is still difficult to bear for a long time.
