When Zhang Yifan entered the light gate, after a short period of time, he came out of the light gate with a bright eye, and the light gate behind him disappeared without a trace, and no trace could be found.

Zhang Yifan didn't care about this, he was used to this kind of assessment, and then he began to look at the surrounding environment.

The first thing that caught my eye was a lake, the lake was relatively calm, and occasionally there was some unusual breath, and Zhang Yifan found that it was some demon beasts in the water after investigation.

The lake is overgrown with weeds and appears to be a swampy place. He began to explore the place, and after a stick of incense, he came to a conclusion.

It is a swampy land with seven lakes, each of which is not small, and is tens of miles in size. There seem to be all kinds of plants growing on the lake, and from time to time some monsters will emerge from the lake and swallow these plants. Nothing else, everything seems to be fine.

Zhang Yifan secretly observed, and he found that the aura of these demon beasts in the water did not seem to be large, only the level of two or three demon beasts, and those plants on the water seemed to be just some ordinary aquatic plants, occasionally mixed with some spirit grasses, which were also the lowest level, and there was nothing special.

After searching for a day or two, Zhang Yifan found nothing, he couldn't find the opportunity for the trial here, and even when he entered the lake and killed some demon beasts, he found nothing.

Those demon beasts seem to be endless, killing a batch will appear again, and there will be nothing left behind, these demon beasts are also composed of illusions.

After the previous trial, Zhang Yifan already had some conjectures in his heart, secretly thinking that the trial scene he was experiencing at present seemed to have something to do with the mutual growth and restraint in the five elements.

In the metallic environment, gold gives birth to water, so there will be a blue demon dog, which is also an opportunity to pass the trial. The environment here is obviously a water-attribute environment, and under the aquatic wood, the opportunity for the trial should be on the wood-attribute things, but what wood-attribute things are in this lake?

Zhang Yifan looked at a lake in front of him in confusion.

The first thing he paid attention to was the plants in the lake, these plants were relatively ordinary and didn't see anything special, and once they appeared, they were quickly devoured by the demon beasts in the water, and basically there was no change, and at the same time, the first plants would soon appear, and they would be endless.

Zhang Yifan was a little curious about how the plants in the water appeared, and after careful observation, he found that there didn't seem to be anything special, and finally he determined that these plants also seemed to be transformed.

It's magical, but it seems to be very ordinary, and there are no clues.

Zhang Yifan was a little unwilling, he felt that some clues should be hidden in these inconspicuous-looking plants.

With a flash of inspiration, he opened his fiery purple eyes, and his lilac eyes swept towards the lake, and then he found some clues.

There was a tiny seed-like thing that glowed with cyan brilliance that would attract some demon beasts to swallow it as soon as it appeared, and the whole process took less than ten breaths, and it was difficult to find it among so many plants.

Fortunately, Zhang Yifan's current fiery eyes and purple eyes secret method has initially had the shadow of supernatural powers, and after so many years of use and physical strengthening, he can now see twenty miles away, and the time that lasts has exceeded the time of two teas.

Zhang Yifan used his fiery eyes and purple eyes to search the entire lake, and only found that there were cyan seeds in the previous place.

So he vaguely knew some rules in his heart, and waited for about a cup of tea in the same place, and the cyan seed reappeared as he expected, and Zhang Yifan began to guard the cyan seed under joy.

At the beginning, only some two- or third-level water-attribute demon beasts came to devour the cyan seeds, but they were easily dismissed by Zhang Yifan. Then something surprised him, and after an hour, the green seed actually began to sprout and grow a seedling.

After Zhang Yifan saw the change, his expression was shocked, his conjecture was really not wrong, as long as he guarded this kind of child, there would definitely be some changes.

As the seedlings grew up, the aura of the water-attribute demon beasts attracted became stronger and stronger, and after six hours, there had been a fourth-level demon beast attack, but these were obviously not a threat to Zhang Yifan, and the seedlings had grown into half-zhang tall saplings at this time.

A day later, the last thing that came was a sixth-level Dacheng water-attribute demon beast with a value of three or four demon beasts, and when Zhang Yifan got rid of them one by one, the sapling had already grown into a one-zhang high spirit tree.

Then, after the cyan brilliance of the spirit tree flashed, a cloud silver talisman floated out from the trunk of the tree, and after Zhang Yifan took it away, he began to turn to the other lakes in the swamp.

With the effect of fiery eyes and purple eyes, Zhang Yifan easily identified the location of the cyan seed, so that he could easily obtain seven Miyun silver talismans in a row.

Those water-attribute demon beasts might cause some trouble to other ordinary foundation building period cultivators, but there was no difficulty for Zhang Yifan.

Besides, he vaguely felt that the strength of these phantom demon beasts seemed to be inferior to the strength of real demon beasts, mainly because they were more skilled in cooperating with each other and were not afraid of life and death.

When Zhang Yifan got the seventh Miyun Silver Talisman in his hand, a light gate appeared not far from the center. This was a sign that he could leave this place, but Zhang Yifan didn't leave there, he knew that every place seemed to hide special rewards, just like the one he had experienced before.

At this time, he easily noticed that the situation in the swamp was a little different from before, a pond the size of a mile appeared in the center, and there was a dark cyan seed floating on the water that exuded a strong wood attribute atmosphere, and the dark cyan seed seemed to be particularly vigorous.

Although the situation is clear at a glance, he only needs to wait and guard here to know what to do next. But inexplicably, Zhang Yifan wanted to see what was under the pool, so he turned on his fiery eyes.

There didn't seem to be anything under the pool, just exuding a faint water attribute aura, which seemed to provide special conditions for the growth of this dark cyan seed, and there was no danger.

Then he looked around to see if there was anything special, and suddenly he paused in one place, but the movement was so light that it was almost imperceptible, and then he took the secret technique and began to wait patiently.

For seven days, Zhang Yifan didn't find anything wrong, and the dark blue seed had grown into a seven-zhang tall tree.

After that, the big tree began to emit an astonishing green light, and then Zhang Yifan felt that there seemed to be something going on on the road in the direction of the seven spirit trees before.

Roar!

Seven roars began to sound in the sky, and then Zhang Yifan used his powerful divine sense to check, and found that seven powerful monsters with a powerful aura similar to tree people were running towards him quickly.

Those seven tree people seemed to have the realm of the Great Perfection in the late stage of foundation building, and when they appeared in front of Zhang Yifan, they did not hesitate to attack.

The branches in the sky turned into thousands of sharp swords and attacked Zhang Yifan overwhelmingly, this power frightened Zhang Yifan, he used the Zhenshen Tower without hesitation, and protected the three Jin Yuangang shields on three sides.

In this way, he finally dodged the first round of attacks, and then Zhang Yifan, who did not plan to sit still, put away the golden yuan gang shield and immediately sacrificed four fierce golden spears to attack these tree people.

The damage of the Burning Golden Spear to these tree people seems to be particularly high, especially now that the power of the four Burning Golden Spears in Zhang Yifan's hands is even more powerful than the inheritance weapon.

Although the tree man was strong and defensive, it was still difficult to deal with Zhang Yifan's attack of driving four top-level magic weapons at the same time.

Soon a tree man will be killed, and when the tree man dies, a flash of light will sink into the large tree in the central pond, and the tree will grow in height.

After a stick of incense, Zhang Yifan killed these tree people one by one, and at this time, the big tree was already fourteen zhang in size, and it was also a big tree.

Zhang Yifan was a little puzzled, the difficulty of the trial in this swampy land seemed to be lower than the previous trial in the metallic hilly land, although these seven tree people had a sixth-level cultivation of great success, but their attributes were single, and their strength was actually average, he didn't use his spirit pet to kill these tree people one by one with just his own magic weapon.

It's just that nothing appeared except for the change of the big tree, which made Zhang Yifan look nervous, and felt that there should be changes here.

Just as Zhang Yifan hesitated and didn't know whether to retreat, the water surface of the pond around the big tree began to roll, as if it had been boiled, and the white mist that came out rushed straight into the sky, wrapping the entire tree, and only the shadow of the big tree could be faintly seen.

Then the strange sound continued, and Zhang Yifan vaguely saw that the big tree in front of him seemed to turn into a big tree man who was only fourteen or fifteen zhang high, and the branches in the sky hung around the tree man, swaying wantonly, making people's scalp numb.

The white mist did not dissipate, but obscured the figure of the big tree man, making it difficult to see. However, the aura emitted by the big tree people has long exceeded the scope of the foundation building period, reaching the level of the early stage of Jindan.

Zhang Yifan's expression changed greatly, although he had some means to deal with the monsters of the Jindan period, he could only protect himself, and it was extremely difficult to repel or even kill them.

The aura of this mysterious big tree man was much stronger than the aura of the Jindan stage monk he had encountered before, reaching the top level of the early Jindan stage, which was not something he could deal with.

Zhang Yifan fled without hesitation and fled towards the light gate.
