Slowly advancing in the dense forest, because it needs to sense whether there is an elixir around him, the speed of the flight is only more than thirty kilometers per hour, and the altitude is almost close to the ground.

This time, he didn't fly with Na Lin in his arms, but let this girl follow behind to practice chasing the wind, and occasionally when he encountered any fierce beast attack, basically Zhang Tiancheng would intervene and deal with it by herself.

In other words, the number of mutated monsters in the depths of the jungle is indeed quite large, of course, these monsters are very deadly to ordinary people, but they are not a threat to Zhang Tiancheng at all, and they can't even pose a threat to Nalin.

After this girl has a few years of internal force as support, her strength, endurance, speed, etc. have been greatly improved, and she has played a very slippery wind knife technique in one hand, although it is not superb, but it can be regarded as entering the house.

Most of the mutant beasts can be easily killed, and even if they encounter difficult ones, they can also cooperate with the wind to protect themselves.

Although her combat strength has grown rapidly, this girl now regrets her rapid growth.

If you don't have strong combat power, you're completely tired of being in the arms of adults now, leisurely admiring the scenery around you, instead of running after adults in a hurry like now, and you're tired and sweating profusely, and you don't have the look of a lady at all.

"Big, big...... I really can't do it anymore...... You can fly with me for a while! After running for more than half an hour, Narin finally opened her mouth out of breath and begged for mercy.

"You can do it, hold on longer!"

"How much longer is it going to last...... I'm running out of breath. ”

"Last night's Creation Pill energy exploded, and your internal strength increased by about 1.5, so you have to hold on for at least a little more time today than yesterday."

"But those new internal forces ...... I can't call it freely...... My lord, will you just let me rest...... It's really tiring. Narin begged for mercy weakly.

In fact, seeing her sweaty appearance, Zhang Tiancheng really wanted to stop and fly with her, but this girl grew too fast because she absorbed the internal force of the Creation Pill and practiced the martial arts, so she could only continue to squeeze her limit value.

"Na Lin, when your shooting really reaches the real limit, those newly increased internal forces will automatically be called up by the body's self-protection function, and then you can take the opportunity to control it, so hold on!"

"Can't you just take a break and continue?"

"I really can't, your spiritual willpower must keep up with the growth of internal force, otherwise your spiritual will will not be able to control those rapidly growing internal forces, and it is likely to go crazy."

Zhang Tiancheng tried his best to explain and encourage, but Na Lin could only insist, running for nearly an hour, and when the shock of exhaustion passed, Zhang Tiancheng stopped, and carefully helped massage and relax his muscles.

The pale-faced girl rested for a few minutes, and finally recovered.

“…… I thought adults were ignoring me just now. Na Lin, who was leaning on Zhang Tiancheng's arms, said with some fear.

"Why, I'm doing this for your own good."

"I know, my lord, did you practice so hard before?"

"I didn't have to work as hard as you in the past, but I would go through life and death tests again and again, and as long as I made a mistake, I would be doomed, so I really envy you that as long as you work hard, you can achieve such tremendous growth."

"That's my luck, if it wasn't for the adults, I would have been eaten by the snake demon a long time ago."

After recovering a little, he went back on the road to find the elixir, but this time he didn't let Narin follow, but flew slowly with the person in his arms, and his divine sense expanded to the maximum range.

Fly slowly all the way, you can roughly detect the creatures within 120 meters on the left and right, and if there is an elixir, you can basically detect it.

Of course, there will be fish that slip through the net, which is also a matter of no choice, anyway, it is as much as you can find, in fact, there are enough things in this mission world.

Now the biggest question is whether you can bring it back, because although there are many elixirs rich in special aura energy, they have not been recognized by the system, and I don't know if it is too low-grade.

That is after the IELTS is packed separately, there are two cubic elixirs, there are dozens of kinds, if you don't bring all these spiritual herbs back, there is definitely a chance to make a lot of practical elixirs.

Although he didn't learn much alchemy, alchemy was essentially just extracting the different energies contained in the elixir and then effectively fusing them together.

Having a keen sense of consciousness can solve many problems in the study of alchemy technology, so making medicine is actually not as difficult as you imagined.

It has been nine months since I came to this world, and the chaotic energy in my body has been refined by about three percent, although the body data detected by the system has not changed, but the strength, speed, and endurance have actually increased a lot.

For example, now you can even rely on pure strength, you can run the speed of a cheetah when you sprint to the limit, and as for endurance, you can take a cheetah out of a dozen streets.

While searching for things around him, he flew slowly, and at the same time thought about some things about alchemy, when he suddenly felt a golden light in front of him and was really stunned.

When I looked at it, I was surprised to see a golden city, or more precisely, a golden castle on an island in a large lake.

It is unclear whether the castle was actually made of gold, but the buildings and even the ground were golden yellow, shining with a dazzling golden glow in the setting sun.

"My God, beautiful city, how did we get here, my lord?"

"Looks like there's a hidden barrier!" As he spoke, he turned around and flew more than ten meters, and sure enough, after passing through a shadowless and invisible barrier, the golden castle disappeared, and even the big lake disappeared.

This discovery really made Zhang Tiancheng very excited, not because that castle might have a huge amount of gold, but because this mysterious enchantment was indeed very awesome, and it should be similar to the stealth formation.

It is even more powerful, because even the divine sense perception cannot detect the situation behind the enchantment, if you master this magical formation and build it into a stealth chip, it is enough to avoid the divine sense detection of the cultivators of the Heavenly and Human Realm.

It is certain that this ruin is not the product of the existing human civilization, and the enchantment can never be created by the existing humans, so this ruin is either a mysterious ancient civilization or a very advanced alien civilization.

One thing is for sure, that awesome civilization has disappeared, otherwise they would definitely be discovered by breaking in just now.

"Sir, can't we go in?"

"You should be able to go in, but once you're in, don't mess with anything."

"Understand, I won't move anything without an adult's command."

"Okay, why don't you go in and have a long experience!"

Now that the unknown civilization has disappeared, there is no need to worry too much, and directly take Narin to fly towards the mysterious enchantment again.

Passing through a barrier barrier of almost a thickness, the Golden City reappeared, and the large lake outside covered an area of four or five square kilometers, and the small island in the center of the lake should be less than one square kilometer in size.

The distance of less than a kilometer was of course a moment, and it fell lightly on the main street of the Golden City, and the divine sense quickly spread out and carefully probed around.

It is certain that the ground is a real gold brick Pucheng road, and even when the divine consciousness extends downward, it is unexpectedly found that this small island in the middle of the lake is a gold mountain at all, although there are still many impurities, but the gold content accounts for at least more than 30%.

It seems that these few square kilometers of the big lake is a huge crater, and this golden mountain is the super-large meteorite.

However, it is a little incomprehensible that a huge meteorite of such weight can hit the opposite side, and it stands to reason that it can hit a super-large crater with a diameter range of more than dozens of kilometers.

"My lord, there's a monster crawling up in the water!" Seeing that Zhang Tiancheng was deep in thought, he couldn't help but remind.

"It's not a monster, it's just a big crocodile!"

"That thing looks like it's going to be eaten!"

"In that case, let's have roast crocodiles for dinner!" As he spoke, he threw out the flying sword directly, and cleaned up the crocodile with three strokes and five divisions, and saw that there were many crocodiles approaching this side in the distance.

Although it was easy to kill, but I didn't want to make the beautiful Golden City bloody, so I immediately took out a small infrasonic vibration generator and placed it by the lake to activate it.

Although the thing was just a small device the size of a palm, and the infrasound fluctuations were so small that humans could barely hear them, it was very conductive into the water, and it successfully shocked all the creatures nearby.

In the perception of the rapidly approaching crocodiles, there is a very powerful overlord declaring the territory here, and whoever relies on the new overlord's near territory will die.

So the group of crocodiles, who originally wanted to quietly approach and kill the unknown intruder, turned around and fled quickly.
