"I see!" Zhang Yang nodded lightly, expressing his understanding, the eighteen cities of Longyang have their own economic pillars and sources, some cities have strong military strength and mainly hunt star beasts, some have rich mineral vein resources, and some have strong manufacturing industries and developed economies, and Yecheng, as the smallest city in the eighteen cities of Longyang, is precisely because of the existence of Ye Xi that Yecheng has a large number of economic resources!

Among the eighteen cities of Longyang, although Yecheng's economy is not the strongest, it is not the bottom, after all, with such a rich water source, it is a safe and effective economic line for Yecheng, and this economic line cannot have any problems, otherwise it will have a huge impact on the development of Yecheng!

This task is big and big, small and small, the change of water volume in Yexi is a situation that happens every year, if it is because of some natural reasons that some of the water volume is reduced, then there is no way, Yecheng's economy will inevitably be affected, this is also a matter of no way,

But if it's for other reasons, their detectives this time will become extremely valuable, the reason why the mission level this time is only E level, the reason is probably because the number of times is too frequent, for how to perform this kind of task, everyone already has the bottom in their hearts, this time to bring them these students, it is just a matter of doing it, it can be regarded as familiarizing with the environment of the Yexi Jungle!

There was nothing to say all night, basically publicizing that they had not encountered any danger, even at night, there were very few star beasts operating within ten miles around Ye City, the steel city wall of Ye City, like a huge star beast king, stood here, no one dared to easily offend the majesty of this steel dragon!

By the next morning, when dawn had just fallen, and the morning sun of Orange Island had just risen, Zhang Yang and they had already left Yecheng for more than forty miles, this distance could already be regarded as going deep into the primeval jungle of Orange Island, and along the way, they could clearly smell the bloody smell that had not yet dispersed, which was the traces left by the star beast fighting in the middle of the night, but after a day, these bloody smells would disappear!

"Everyone hurry up, this time is the best for us, the star beasts fought all night, and they have just returned to the nest at this time, and these star beasts will come out to drink water at noon!"

Second Lieutenant Huafeng ordered to speed up, this is indeed a good opportunity for the exploration team, taking advantage of the rest time of these star beasts to rush some more distances, the length of Yexi is only more than three hundred miles, of course, the reason is that because the establishment of Ye Cheng cut off Yexi, the downstream waterway of Yexi is completely dry, so Yexi is only more than three hundred miles!

And after everyone walked out of 50 miles, the surrounding terrain has gradually undulated, mountains and forests, Yexi meanders in the valley, 30 million miles of Orange Island primeval jungle will naturally not be flat, in the middle of the mountains and forests, river valleys vertical and horizontal, the terrain is extremely complex, although 30 million miles of Orange Island is a huge pasture, but the danger contained in it can not be underestimated!

The 20 reconnaissance teams sent this time, although the total number of people reached 420, but they were also nowhere to be seen in this mountain forest, and they came out for so long, but they didn't even meet any team, and it was easy to hide their bodies in the jungle, plus they were originally cautious when they were advancing, even if the two teams encountered, not very close to each other, it was impossible to find each other at all!

The water flow of Yexi has begun to slow down after 50 miles, although the main river channel is in, but its water volume has been somewhat reduced, the water volume of Yexi is from the water vapor gathered in the surrounding mountains and forests, the water vapor forms water droplets, and then converges in the mountains and forests, through various channels, and finally converges in Yexi, so the more upstream, the smaller the water flow of its main road, it is said that the source of Yexi is a spring, the spring flows silently, which created this Yexi, and also made Yecheng!

"After entering the mountains and forests, everyone should be cautious and vigilant, the fierce beasts in the mountains and forests are rampant, and you will encounter one or two star beasts. If you are unlucky, it is not impossible to meet an eighth-level or even ninth-level star beast or even a star beast king, so you need to be vigilant, any negligence may be death for everyone!" At this moment, even Chen Song and these veterans did not dare to be careless, and even the spirit of publicizing them was highly concentrated!

The detection task is easy to say, but it is also difficult to do, it is necessary to trace the source all the way up the main road of Yexi, and conduct detailed exploration on various large tributaries to observe which waterway has any signs of drying up, so as to make a judgment, but along the way, they did not find anything abnormal!

Although the water flow of Yexi has a decreasing trend, the amount of reduction is not very much, and the amount of water in various places is only reduced, which has caused the reason for the decrease in the water volume of Yecheng downstream, but there is no other special situation, but this is just the beginning, and the inspection of the entire main road of Yexi has not been completed, so the task cannot be regarded as completed, and it is necessary to continue to travel, and it can be said that this detective mission can be truly completed when it reaches the place where Yexi Spring is located!

Although it is close to winter, the temperature of the jungle is still rising quickly, a round of bright sun hovers above everyone's heads, through the direct sunlight of the mountain forest, the leaves in the jungle are lazily pulling the leaves, many star beasts have come out of the nest at this time, go to Yexi to drink, this is no way to stop the thing, it is impossible to surround the birthplace of Yexi for nearly 300 miles for the sufficient supply of water in Yexi, which is definitely a huge economic burden for Longyang Province, and it takes manpower and material resources to surround the 300 miles of the main river！

To build a city downstream, more than 80% of the water in this leaf stream will be used by the alliance, and less than 20% of the remaining water will be used by these star beasts, so it is the best way to establish a leaf city downstream and cut off the leaf stream!

Many star beasts lazily walked out of the mountains and forests, and rushed to the Yexi River from all over the place, these star beasts were large and small, high and low, all of them were star beasts inhabited by this jungle, Zhang Yang even saw an iron-backed black bear swaggering into the distance, it turned out to be a seventh- or eighth-level star beast not far from the iron-backed black bear they hunted only two months ago!
