why Serial Why doesn't serial communication does not work on arduino unoArduino Uno r3 and esp8266 wifiESP8266 WiFi module?

Hello I have a simple problem here. I use esp8266 WIFIan ESP8266 WiFi module and an Arduino Uno r3.

What I want is to receive a Serialserial message from Esp8266 tothe ESP8266 on the Arduino Uno.

noteNote: I set the upload speed of the ESP82666 intoESP8266 to 9600.

void setup()
  {
  Serial.begin(9600);
} 

void loop() {
    Serial.write("hello friend");
    delay(2000);
 
 }

Arduino Uno:

#include <SoftwareSerial.h> 

SoftwareSerial mySerial(10, 11); //rx, tx

void setup() {
  Serial.begin(9600);
  mySerial.begin(9600);
 
} 

String message = "";
boolean check = false; 

void loop() {
 // Serial.println(mySerial.available());
   mySerial.println("hindi nagagana");
  while (mySerial.available() > 0) {
    Serial.println(mySerial.readString());
    check = true;
  }

  if (check==true)
check == true) {
    Serial.println(message);
  } 

  delay(200);
}

orOr any idea on how to control via internet the Arduino Uno via the internet, such as a simple LED blink  ? I

I used firebaseFirebase for databases an I plan to use ReactJs for webApp/Native App (nodeJs).
