The cold climate of Dongyue Lake had no effect on Qin Yi and the masters of the Xuan War Department at all.

The members of the Xuanzhan Department who arrived first have already built a simple temporary camp by the lake, and some commonly used communication equipment and geological exploration equipment have been prepared.

Professor Wan is the leader of the geological exploration team, he is a leader in the field of geology in the alliance, and has a lot of academic research in geology.

Now it is a harsh winter, Dongyue Lake has been completely frozen, the thinnest part of the ice is more than 70 centimeters, and the last place even reaches 1.5 meters, the special vehicle responsible for geological exploration work can easily drive on the ice without worrying about the ice breaking.

When Qin Yi and the others arrived, the expert group had already sent the first day's research report.

"Minister Zhong, it stands to reason that the air temperature of minus 5 degrees will not make the entire surface of Dongyue Lake freeze, after all, this is living water. The ice is also completely thicker than it should be, and we suspect that there may be some other factors at the bottom of the lake that increase the temperature inside the lake, which requires professional divers to go down to the lake and provide us with some detailed data. ”

"Moreover, the proportion of organic matter in the lake water is much lower than the data recorded by the local geological department in previous years, which is even more undesirable. It's weird. ”

"Thank you for your hard work, Professor Wan, you guys should take a rest first. I'll arrange the things to go to the lake. ”

The average water depth of Dongyue Lake is 18.5 meters, and the deepest part of the lake center is 35.6 meters.

"Minister Zhong, you arrange the water manpower first, and I'll go to the lake to have a look."

Qin Yi and Minister Zhong talked for a while, and then took Ke'er and shot towards the center of the lake, with a very fast speed.

"Childe, the aura of heaven and earth here seems to be lower than normal."

Qin Yi also felt it, but he didn't care. The distance of 20 kilometers is 10 minutes, and this is still when the speed is controlled by two people.

————————

Qin Yi looked around, and the place where he stopped now should be regarded as the area in the middle of the lake.

"Give me the Qinglan sword."

Qin Yi stretched out his hand and grabbed it, and the Qinglan sword behind Ke'er happily flew out of the scabbard, and instantly appeared in Qin Yi's hand, the sword body was all blue, and the light was restrained. It's no longer as radiant as it used to be, and it's eye-catching from afar.

Qin Yi looked at the Qinglan Sword in his hand, feeling that it was becoming more and more spiritual, and he really liked it more and more.

Qin Yi volleyed his body up to 10 meters in the air, and then activated his True Qi, turning the tip of the Qinglan Sword vertically downward, and his body quickly rotated around. The ice surface, which was originally intact, immediately appeared with a large ring with a diameter of 5 meters.

The figure fell, and handed the Qinglan Sword to Ke'er with his backhand, Qin Yi put his hands flat on the round ice cube, and with a slight movement, he sucked up the huge ice cube and threw it aside, revealing the blue lake below.

"A lot of little fish, Childe."

The lake water is very clear and crystal clear, Ke'er gently picked up a little lake water and took a sip, feeling a little cold, a little sweet, very comfortable.

"Childe, let's find time to pack some and take it away, drink it."

Ke'er went out with Qin Yi, no longer as restrained as in Beijing-Shanghai B, Qin Yi looked at her and smiled slightly, maybe this is the real Ke'er.

"Well, let's get down to business first, and we'll talk about it later."

Qin Yi poked out his divine sense and probed vertically down along the broken ice.

In the shallow water, large schools of fish swim by from time to time, but as the depth increases, the number of fish becomes less and less. Qin Yi also occasionally saw some pale blue fish without scales.

When the divine consciousness went down to 20 meters, everything was still normal, and when it reached about 30 meters, Qin Yi's divine consciousness suddenly had a cold feeling, and this feeling quickly spread all over Qin Yi's body.

Qin Yi hurriedly sat down cross-legged on the ice, and the Divine Dragon True Qi quickly ran in his body, expelling the cold feeling in his body.

It's so weird, what happened just now, without warning. Is it an unknown heaven and earth aura? The bottom of the lake is really too abnormal.

"Childe, are you alright?"

"It's okay, I was careless just now."

Qin Yi adjusted his state and probed his divine sense again, because he was on guard, his divine sense was not affected by that cold breath like last time, and he went down to the bottom of the lake smoothly.

There is almost no silt at the bottom of the lake, with a thick layer of fine sand at the top and rocks of various sizes below.

Qin Yi went deeper than 10 meters below the bottom of the lake, but found nothing abnormal, so he spread his divine sense along the bottom of the lake to all sides. When his divine sense reached the limit, he still didn't find anything abnormal, so Qin Yi had no choice but to give up.

When he retracted his senses, he took a few scaleless blue fish with him that he had just discovered.

"Let's go, let's go back first."

Qin Yi threw a few fish that he had caught to Ke'er, then got up and walked back.

————————

In the temporary camp of the Xuanzhan Department by the lake, a circle of five people was chatting around a fire, on which was a large iron pot, in which a pot of milky white fish soup was boiling, and a rich aroma wafted out of the pot.

"Senior, this is a good thing, blue ice fish, it's still so big, it's rare to have one, but it's a whole five!"

Zhong Liang stirred it with a spoon, first serving Qin Yi a full bowl of fish soup, and then giving each of the others a bowl.

"Well, it's tender and smooth, there's no fishy smell, it's good, this soup is good."

Qin Yi took a sip and immediately liked this blue ice fish soup.

"This is freshly fished and stewed, and the water from Dongyue Lake is used, it is estimated that I will enjoy this time in my life, and it is comfortable to follow my predecessors, haha."

After a few people drank it, they each filled a bowl, and the rest of Zhong Liang asked the people from the Xuan War Department to take it and divide it.

"Minister Zhong, have you found any traces of those outsiders?"

"Not yet, they haven't been seen since the last time they retreated, but I think they should be nearby."

"You can send all the men out tomorrow, the camp has me and Ke'er, it should be fine."

"Okay senior."

The exploration proceeded in an orderly manner, and nothing was discovered for the first two days.

Late at night on the third day, most of the people in the camp had already slept, and the night was quiet, except for the occasional crackling sound of burning wood.

Qin Yi was sitting in the military tent, extracting the aura cultivation of the Divine Dragon Order. Cultivating to the realm of refining gods, it is too difficult to improve, every time you improve a realm, it will take decades, it is almost impossible, unless you use some heavenly treasures.

Qin Yi's soul was sucked into the Divine Dragon Space because of an accidental death last time, in that special case, time is equivalent to standing still, Qin Yi has cultivated for hundreds of years before he has reached the realm of God Refining Dacheng, and he is still far from the consummation of God Refining.

When cultivating, Qin Yi habitually released his divine consciousness to envelop Zhou Wei's space to prevent some unexpected situations from disturbing his cultivation.
