Tian Buhui's detection equipment is extremely advanced compared to others, the detection range is wide enough, and the detection is also very careful.
However, one drawback is that it is impossible to detect items hidden under the surface, or under water like the cold pool.
Dudu controls the drone to touch the water when picking elixirs. It detects that the water temperature is abnormal and then issues a warning.
"Dudu, is there any way to investigate more carefully?"
“Need to buy an underwater detector!”
"Then buy it!"
Tian Buhui purchased an underwater detector from the system, worth a thousand low-grade spiritual stones.
The streamlined appearance is like a small torpedo. It is equipped with various equipment and has night vision capabilities. The dark underwater bottom can also be displayed with a high-definition camera.
After Dudu connected to the signal, they put the detector into the cold pool.
Tian Buhui and Yi Bing took tablets and looked at the pictures under the water.
All that could be seen was deathly silence. There was no living thing in the dark water, not even a single swimming fish.
After diving for hundreds of meters, there was still no sign of reaching the bottom, and the images transmitted back gradually began to become blurry.
"Dudu, what's going on?"
"The temperature in the water is too low and the equipment may be damaged!"
"What?"
Tian Buhui was a little helpless. The technological equipment had good functions, but the production materials were limited and could not withstand the extreme environment of the world of immortality.
There is no time now to replace the shell and engrave the formation on it. We can only hope that it can send back useful information before it is scrapped.
When the detector dived to 200 meters, it was still bottomless, the surroundings were still dark, and nothing was found.
At this time, the picture on Tian Buhui's tablet shook a few times and then disappeared, completely losing the signal of the detector.
"Nah!" He cursed secretly, this was really a waste of money.
A thousand spiritual stones, even if his automatic factory was running at full capacity, it would take him half a day to earn it.
"Otherwise, forget it, I don't know what's going on here." The tablet in Yi Bing's hand also lost its screen.
"Forget it?" Tian Buhui hesitated.
Not to mention that he had a hair-plucking personality, but he was still a little unwilling to accept that he had suffered a loss and gained nothing.
Seeing him like this, Yi Bing said, "How about I go down and have a look? I haven't done anything along the way."
"What did you say?" Tian Buhui said angrily: "You are kidding! If you, a little girl, are allowed to go down here, how do you want the majority of netizens to think of me? Don't follow me and say such things in the future!"
"I..." Yi Bing didn't think too much. She just felt that the two of them were working together and wanted to do their part.
I didn't expect Tian Buhui's reaction to be so intense, and I didn't know what to say for a moment.
"Okay, stop talking. I'll go down and take a look. If it doesn't work, we'll give up."
"Well, be careful." Yi Bing didn't dare to refute.
Although Tian Buhui said something with a bad attitude, she knew it was for her own good and felt an inexplicable warmth in her heart.
"Bang bang bang~"
Tian Buhui took more than a dozen Vajra Talismans on his body and put up layers of protective shields.
This wasn't the end yet, he squeezed the magic formula again to hold up a spiritual shield.
Since the last time he accidentally released a super fireball, he discovered that his spell seemed to be somewhat special, having the same function as inflating air.
As long as you continue to output mana inside, the ability of the spell will be enhanced.
He continued to input spiritual power into the spiritual power shield until it was almost two centimeters thick.
You know, other people's shields are only a thin layer, and his shield is almost equivalent to others' twenty or thirty layers.
Yi Bing looked at him from outside and couldn't see anyone inside at all. She could only see a glowing oval dome.
Tian Buhui took out a few pills and drank them to replenish his mana. He called out to Yi Bing to be careful on top.
Driving his dome protective shell, he slowly sank into the cold pool.
At the beginning, everything was as usual, the surroundings were pitch black, and there was no sign of life.
It wasn't until he dived to 400 meters that he suddenly felt a slight chill invading his whole body.
"Nima, what kind of cold air is this? Can it penetrate such a thick shield like mine?"
Looking at the bottom of the pool, there seemed to be a faint light.
But the cold air couldn't hurt him yet, so he gritted his teeth and continued to dive.
Nearly a hundred meters further down, the light from the bottom of the pool became more and more obvious.
He was overjoyed, there was indeed a treasure down there!
Continuing to dive down for several dozen meters, we could already see the bottom of the cold pool clearly.
I saw dozens of human bones scattered densely underneath. The skin and flesh had melted away, leaving only white bones. It was unknown how many years they had been there.
He guessed that these people, like him, discovered the specialness of Hantan and died here when they came down to investigate.
The secret realm of Huanming can only be entered during the Qi Refining Period. These people all died here, indicating that this treasure should be beyond the scope of the Qi Refining Period.
Maybe it will be a foundation-building elixir or a treasure of a higher level.
After understanding this, Tian Buhui was secretly happy. Just because he couldn't get it in other Qi Refining Periods, it didn't mean that he couldn't get it.
Not to mention anything else, just his spiritual shield, which is probably as good as that of a foundation-building master.
Find the location where the light comes from and dive slowly.
"Kaka~"
The surface of the spiritual shield made the sound of being cracked by the extreme cold.
Tian Buhui was startled and quickly stabilized his mind. He fired the magic formula in his hand, and the spiritual power was continuously input into the spiritual power shield.
Gradually, he saw the full picture of the luminous object clearly.
It is a small bronze cauldron one foot square, with a sealed lid and covered with mysterious runes. The bright light is caused by the flow of spiritual power in these runes.
The cold air around it does not seem to be emitted by the small tripod, but seems to be emitted by the items sealed within the tripod.
"Kaka~"
As he continued to get closer, the shield shattered faster.
He didn't dare to use his spiritual consciousness to detect it. The intensity of this cold air might even freeze his spiritual consciousness.
"Never mind!" He waved his hand and put Xiaoding into the system space.
His system space is very special, and the time inside seems to be frozen, so he is not afraid of the cold air corroding the things inside.
As Xiaoding disappeared, the temperature at the bottom of the pool began to rise steadily, and his spiritual shield also stopped shattering.
There was no rush to come up and they searched the pond. After dozens of corpses, they only found a dozen shabby storage bags.
I don’t know if other people’s storage bags were damaged by the cold, or if they were worn away over the years.
After carefully searching the bottom of the pool again, and finding nothing of value, he began to rise.
Yi Bing was a little anxious waiting alone above, but Tian Buhui didn't make any movement for so long.
She couldn't check the situation below, so she couldn't help but feel worried.
Strangely enough, as long as someone he cares about disappears, no matter who he is, he will not think the best, and will always think that he will encounter some kind of accident.
This is the situation Yi Bing is in now, but she hasn't realized yet that Tian Buhui has become someone she cares about.
